Description

Technology Field

[0001] The present invention relates to information linkage technology between an intelligence and reconnaissance sensor system and an external system, and more specifically, to an integrated linkage device for constructing an intelligence, reconnaissance, and surveillance (ISR) sensor network that links data acquired from a plurality of intelligence and reconnaissance sensor systems, such as radar, electro-optical cameras, infrared cameras, radio wave receiving equipment, and seismic vibration sensors, and transmits said data to a command and control system or weapon system through a plurality of communication networks.

[0002] Furthermore, the present invention relates to a technology for evaluating the reliability of target information collected from the surveillance and reconnaissance sensor system in conjunction with external environmental conditions, and for performing data processing, communication control, and device protection control by reflecting together the internal thermal state of the housing of the integrated interlocking device, the electromagnetic leakage state, the communication power state, and the mechanical deterioration state of the connector part. Background Technology

[0003] In the field of surveillance and reconnaissance, the importance of technology that links multiple sensor systems to collect various forms of target and environmental information and transmits the collected data to command and control systems or weapon systems is steadily increasing. For example, radar can provide detection information such as distance, speed, and bearing; electro-optical and infrared cameras can provide image-based visual information; and auxiliary sensors, such as radio receivers or seismic sensors, can provide additional information regarding specific environmental changes or physical vibrations. Since these sensor systems often have different interfaces and data formats, integration technology may be required to accommodate these sensor systems within a single device and transmit them to necessary external systems.

[0004] However, conventional sensor interlocking devices often focus primarily on data format conversion or message relay functions, which may limit their ability to account for hardware and environmental constraints encountered in actual operating environments. For example, in structures where multiple interlocking and communication devices are densely packed within a housing or additional interlocking modules are repeatedly combined, electromagnetic interference or communication instability may occur due to heat accumulation, degraded shielding performance, grounding discontinuities, and the formation of micro-air gaps. Yet, conventional technology often performs protection operations based solely on internal temperature or simple device status, which may fail to adequately reflect the combined effects of thermal and electromagnetic factors.

[0005] Furthermore, while target information acquired from multiple sensors is often evaluated based primarily on simple signal strength, data presence, or format compatibility, external conditions in actual field environments—such as fog, sea fog, rain, condensation, sensor axis alignment errors, and polarization mismatches—can affect the possibility of target identification. Nevertheless, conventional technology fails to accurately reflect the influence of such physical environments, raising the possibility that information with a signal present but low actual identification reliability may be transmitted to higher-level systems without modification.

[0006] Furthermore, regarding the transmission control of communication devices, conventional methods may involve adjusting the transmission output based on the remaining battery level or simple distance conditions; however, in actual operating environments, factors such as increased internal battery resistance, voltage drop at the start of transmission, shielding of the first Fresnel zone, polarization mismatch, and platform attitude shaking may interact. Therefore, relying solely on transmission control based on a simple remaining level may make it difficult to adequately reflect actual power margins or radio wave propagation efficiency.

[0007] Meanwhile, in the structure of a modular integrated interlocking device, the connector portion may be continuously exposed to repetitive fastening and unfastening, vibration, shock, and thermal stress. In such cases, relying solely on the cumulative number of fastenings may not adequately reflect the actual degree of degradation; factors such as changes in insertion and release forces, contact wear, minute slip displacement, and reduced latch engagement strength must be considered together to more appropriately assess the actual state of lifespan degradation. However, conventional management has often been limited to simple usage counts or the presence of minor defects, which may fail to sufficiently reflect lifespan variations resulting from actual operational harshness. The problem to be solved

[0008] One objective of the present invention is to provide an integrated interlocking device capable of accommodating multiple surveillance and reconnaissance sensor systems having different interfaces and data formats in a single integrated interlocking device, and transmitting data acquired from the sensor systems to a command and control system or a weapon system through multiple communication networks.

[0009] Another objective of the present invention is to provide a control structure capable of performing protection operations, such as data throughput limiting, heat dissipation, or module selection control, in stages by reflecting together the heat accumulation state, shielding opening state, ground discontinuity state, micro-air gap state, and electromagnetic energy residual state inside the housing that may occur during the process in which an additional interlocking module is coupled to the integrated interlocking device and a plurality of interlocking units and communication units are operated together.

[0010] Another objective of the present invention is to provide a structure capable of evaluating detection reliability in stages according to actual operating environments by reflecting not only positive factors such as thermal contrast and motion matching, but also attenuation or deduction factors such as condensation margin deficiency, scattering attenuation, polarization mismatch, and sensor axis alignment error, together with respect to target information acquired from heterogeneous sensors such as radar, electro-optical cameras, infrared cameras, and seismic motion sensors.

[0011] Another objective of the present invention is to provide a structure capable of performing transmission output adjustment, survival communication mode switching, or alternative communication path switching by reflecting residual battery energy, survival threshold energy, battery internal resistance, voltage drop rate, first Fresnel zone shielding rate, polarization mismatch loss, and attitude oscillation of the platform together in the transmission control of a communication device.

[0012] Another objective of the present invention is to provide a structure that reflects the cumulative number of times the connector part is fastened, changes in insertion and separation forces, contact wear, cumulative micro-sliding displacement, thermal stress, and residual coupling force of the latch together, thereby more precisely tracking the mechanical fatigue and lifespan degradation state of the connector part and utilizing it for maintenance warnings or power protection control.

[0013] The problems of the present invention are not limited to those mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the description below. means of solving the problem

[0014] In an integrated interlocking device for constructing an intelligence, reconnaissance, and surveillance (ISR) sensor network according to an embodiment of the present invention for solving the above problem,

[0017] A data processing unit connected to the above-mentioned interlocking unit and the above-mentioned communication unit, configured to determine data processing priority, communication priority, and device protection operation by reflecting together surveillance and reconnaissance data received through the above-mentioned interlocking unit and physical state data of the above-mentioned integrated interlocking device;

[0018] A connector part to which the above interlocking unit and the above communication unit are combined; and

[0019] It includes a housing that accommodates the data processing unit, the interlocking unit, the communication unit, and the connector unit.

[0020] The above data processing unit is,

[0021] By combining the coupling state of the additional interlocking module connected through the connector part, the internal thermal state of the housing, the state related to electromagnetic leakage of the housing, and the state related to the detection reliability of the surveillance and reconnaissance data,

[0022] The method is characterized by determining whether the surveillance and reconnaissance data is a transmission target or a transmission priority, and controlling the communication unit and the interlocking unit to perform at least one of limiting the data throughput, heat dissipation operation, or selective module control for the integrated interlocking device.

[0023] The above-mentioned interlocking unit is,

[0024] An Ethernet interlocking unit for receiving detection messages from radar or network-based surveillance and reconnaissance equipment, and

[0025] It includes a serial linkage unit for receiving surveillance and reconnaissance data from an electro-optical camera, an infrared camera, a seismic sensor, or serial interface-based surveillance and reconnaissance equipment, and

[0026] The above data processing unit is,

[0027] The number of additional interlocking modules connected to the connector portion, the shielding opening ratio which is the ratio of the effective opening area with reduced shielding continuity to the total shielding area of ​​the housing, the duration of the temperature rise inside the housing, the thermal return delay time to return to a reference temperature range, the discontinuity of the ground path impedance, the micro-pore ratio of the junction, and the electromagnetic energy residual time of the cavity inside the housing are configured to be obtained as physical state data.

[0028] The above data processing unit is,

[0029] A reference stress value is set based on the number of the additional interlocking modules and the shielding opening ratio, and

[0030] Calculate the degree of heat accumulation from the above temperature rise duration and the above heat return delay time and add it to the above reference stress value, and

[0031] When at least one of the above micro-pore ratio, the above ground path impedance discontinuity, and the above electromagnetic energy residual time exceeds a preset leakage criterion, a thermal-electromagnetic stress index is calculated by applying a non-linear additional weight to the cumulative score reflecting the above reference stress value and the above heat accumulation degree.

[0032] If the above thermal-electromagnetic stress index exceeds the first threshold, the data packet throughput or message processing allocation for the above additional interlocking module or the above interlocking unit is limited, and

[0033] If the above thermal-electromagnetic stress index exceeds the second threshold, the rotational speed of the cooling fan is increased or an auxiliary heat dissipation operation is performed, and

[0034] When the above thermal-electromagnetic stress index exceeds a third threshold, the power supply or functional operation to the recently connected additional interlocking module or the module with a lower priority is sequentially restricted, characterized by

[0035] The above data processing unit is,

[0036] The above shielding opening ratio is calculated by dividing the sum of the effective opening areas of the connection parts where the shielding cover has been removed or the shielding performance has been degraded by the total shielding area, rather than by the ratio of the number of ports.

[0037] The above micro-pore ratio is calculated as the ratio of the incomplete contact area to the total joint length or total joint area using the contact resistance distribution or leakage current distribution measured along the shielding gasket or joint, and

[0038] The above ground path impedance discontinuity rate is calculated using the reflection characteristics, impedance deviation rate, or degree of ground continuity degradation on the connector pin joint or ground path, and

[0039] In the case where only the sensor value of any one of the multiple temperature sensors rises abnormally, if an abnormal state is not simultaneously confirmed in at least one of the micro-air gap ratio, the ground path impedance discontinuity, and the physical coupling state of the additional interlocking module, the weighted reflection and step control of the thermal-electromagnetic stress index are suspended for a certain hold time and the multiple sensor values ​​are cross-verified, the configuration is characterized by.

[0040] The above data processing unit is,

[0041] Tropical contrast corresponding to the average temperature difference between the target area and the background area in a thermal or infrared image, and

[0042] Initial detection reliability is formed based on motion matching corresponding to the correlation or agreement between the Doppler change pattern, velocity change pattern, or distance change pattern acquired from the radar and the time-sequence response pattern of the seismic sensor or auxiliary sensor, and

[0043] Condensation margin deficit corresponding to the difference between the dew point temperature and the lens surface temperature calculated based on ambient temperature and relative humidity,

[0044] A scattering attenuation coefficient corresponding to the amount of optical attenuation or reduction in visibility caused by fog, rain, sea fog, snow, or atmospheric moisture particles,

[0045] and subtracts and corrects the initial detection reliability by reflecting the polarization mismatch loss corresponding to the difference between the transmission polarization direction and the reception polarization direction or the reflected wave polarization direction of the radar-type sensor, and

[0046] The final detection reliability is calculated by expanding the above subtraction correction amount as the sensor axis alignment error corresponding to the angular difference between the radar center axis and the optical sensor center axis increases, and

[0047] It is characterized by classifying surveillance and reconnaissance data into one of a high-reliability class, a medium-reliability class, and a low-reliability candidate group according to the above-mentioned final detection reliability, and

[0048] The above data processing unit is,

[0049] The allowable range of the above sensor axis alignment error is set based on the minimum overlap margin at which the radar beam width and the optical sensor's field of view can maintain a common detection area, and

[0050] If the above sensor axis alignment error exceeds the above allowable range, the corresponding surveillance and reconnaissance data is not immediately discarded but is converted into a low-reliability candidate group or a re-verification target group, and

[0051] If the above final detection reliability is of the high reliability grade, the corresponding surveillance and reconnaissance data is classified as priority transmission target data and transmitted first to the command and control system or weapon system through the above communication unit, and

[0052] If the above final detection reliability is at an intermediate reliability level, it is classified as auxiliary data for requesting reconfirmation of adjacent surveillance and reconnaissance assets or other sensor systems, and

[0053] If the above final detection reliability is in the low-reliability candidate group, the immediate provision of strike parameters is withheld and the target is displayed as a low-priority target on the operator screen, or it is maintained in a logical standby state until subsequent data regarding the same target is determined to have normal reliability for a number of consecutive times exceeding a preset number.

[0054] Even if the scattering attenuation coefficient or the condensation margin deficit increases rapidly at a single point in time, if the humidity change, visibility change of adjacent environment sensors, or the change trend over consecutive points in time do not support this, it may be determined as a temporary disturbance and configured to withhold immediate reduction of the final detection reliability. Effects of the invention

[0055] According to the present invention, a plurality of surveillance and reconnaissance sensor systems are accommodated in a single integrated interlocking device, and data acquired from the sensor systems can be transmitted to an external system through a plurality of communication networks, thereby contributing to the integrated performance of sensor interlocking and information propagation.

[0056] In addition, according to the present invention, a thermal-electromagnetic stress index is formed by reflecting the combined state of an additional interlocking module, the heat accumulation state inside the housing, and the electromagnetic leakage state together, and since data throughput limiting, heat dissipation control, or module selection control can be performed according to the index, it is possible to respond at an earlier stage to complex internal state changes that are difficult to reflect based on simple temperature criteria alone.

[0057] In addition, according to the present invention, since the final detection reliability can be determined by progressively reflecting thermal contrast, motion consistency, condensation margin deficiency, scattering attenuation, polarization mismatch, and alignment error with respect to target information acquired from heterogeneous sensors, it can be utilized to adjust the level of utilization of target information in a more finely detailed manner in situations where the influence of the external physical environment is significant.

[0058] In addition, according to the present invention, since the transmission output, viable communication mode, and alternative communication path can be controlled by considering not only the remaining battery level but also internal resistance, voltage drop rate, shielding status of the propagation path, polarization loss, and attitude fluctuation, it can contribute to maintaining core communication functions while adjusting the balance between power consumption and communication stability.

[0059] In addition, according to the present invention, since the fatigue score and lifespan degradation status can be determined by reflecting the cumulative usage history of the connector part and accelerated degradation factors due to harsh environments together, the degradation trend according to actual operating conditions can be reflected more precisely compared to a maintenance judgment method based on the number of simple connections.

[0060] In addition, according to the present invention, since the internal housing state determination, detection reliability determination, transmission control, and connector life prediction can be performed in conjunction under the control of the same data processing unit, sensor data processing, hardware protection, and communication control can be utilized to manage them as a single continuous operating system rather than as separate functions.

[0061] The effects according to the present invention are not limited to those exemplified above, and a wider variety of effects are included within the present invention. Brief explanation of the drawing

[0068] In addition, the operation embodiments and configurations described in a general manner without being explained in detail below follow the prior art and are omitted in order to focus on describing the purpose of the present invention and the resulting effects.

[0069] Furthermore, in describing the present invention, if it is determined that a detailed description of related known functions or configurations may unnecessarily obscure the essence of the invention, such detailed description is abbreviated or omitted.

[0070] An integrated interlocking device according to one embodiment of the present invention may be configured to be positioned between one or more surveillance and reconnaissance sensor systems (10) and one or more communication networks (20) to interlock data collected from the surveillance and reconnaissance sensor systems (10) and to transmit the data to a command and control / weapon system (30). The surveillance and reconnaissance sensor systems (10) may include radar, electro-optical / infrared cameras, radio wave receiving equipment, seismic vibration sensors, infrared sensors, etc., and the communication networks (20) may include at least one of a satellite communication network, a mobile communication network, a wireless communication network, and a wired communication network. The integrated interlocking device may be provided to accommodate differences in the interface of the surveillance and reconnaissance sensor systems (10) and differences in the connection method of the communication networks (20), and to this end, it may include a housing (110), a data processing unit (120), an interlocking unit (130), a communication unit (140), and a connector part (150).

[0071] The data processing unit (120) may be provided in the form of a central processing unit board equipped with software that controls the linkage unit (130) and the communication unit (140). The linkage unit (130) may perform protocol and signal processing with the surveillance and reconnaissance sensor system (10), and the communication unit (140) may perform protocol processing and transmission control for connection with the communication network (20). The connector part (150) may provide physical connection between each unit and connection with an external device or an additional linkage module (200), and the housing (110) may be configured to accommodate each unit internally.

[0072] According to one embodiment of the present invention, the basic configuration of the integrated interlocking device may be configured to handle one surveillance and reconnaissance sensor system (10) and one communication network (20). For example, the integrated interlocking device may be implemented in a structure that is connected to one radar and transmits target detection information received from the radar to a command and control / weapon system (30) through one wired communication network. In this case, at least one data processing unit (120), one interlocking unit (130), one communication unit (140), and a connector part (150) may be arranged inside the housing (110).

[0073] In the above basic configuration, the linkage unit (130) may be implemented as an Ethernet linkage unit (131) or a serial linkage unit (132) depending on the interface method of the surveillance and reconnaissance sensor system (10). For example, when the radar transmits an Ethernet-based detection message, the Ethernet linkage unit (131) can receive the detection message by performing TCP or UDP communication. On the other hand, when the surveillance and reconnaissance sensor system (10) uses a serial interface, the serial linkage unit (132) can receive data according to at least one of RS-232, RS-422, RS-485, USB, SPI, or I2C methods. The data processing unit (120) can organize the received data into an internal processing format and then transmit it to the communication unit (140) to enable external transmission.

[0074] According to one embodiment of the present invention, the integrated interlocking device may be interlocked with a plurality of types of surveillance and reconnaissance sensor systems (10). For example, the integrated interlocking device may be connected to at least two of a radar, an electro-optical / infrared camera, a radio wave receiving device, a seismic motion sensor, and an infrared sensor. In this case, the data processing unit (120) may separate processing paths by reflecting different data formats and reception cycles for each sensor system.

[0075] For example, the data received from the radar may be a detection message regarding the distance, bearing, speed, detection time, etc. of a target, the data received from the electro-optical / infrared camera may be an image frame or image metadata, and the data received from the radio wave receiving equipment may be signal detection information by frequency band. In addition, the data received from the seismic sensor or infrared sensor may include information on whether an event has occurred, detection intensity, or state change. Instead of simply processing data of different formats as described above using the same transmission procedure, the data processing unit (120) may organize the data by applying a pre-set classification rule or message rule according to the type of sensor.

[0076] The above-mentioned interlocking unit (130) may be arranged in one or more ways to accommodate physical and logical connections with multiple sensor systems. For example, the radar may be connected via the Ethernet interlocking unit (131), and the seismic vibration sensor and infrared sensor may be connected via the serial interlocking unit (132). Accordingly, the integrated interlocking device may accommodate different port structures and signal formats depending on the type of sensor.

[0077] According to one embodiment of the present invention, the integrated interlocking device can transmit information collected from the surveillance and reconnaissance sensor system (10) to a command and control / weapon system (30) through at least one of a plurality of communication networks (20). The communication network (20) may include a satellite communication network, a mobile communication network, a wireless communication network, and a wired communication network, and the communication unit (140) may be provided to support connection with each communication network.

[0078] For example, the satellite communication network may be used through a connection with a separate satellite communication service terminal device. In this case, the integrated interlocking device may be connected to the satellite communication service terminal device via Ethernet or serial. Additionally, the mobile communication network may be connected through a mobile communication function built into the integrated interlocking device, the wireless communication network may be connected via a wireless radio in the VHF, UHF, or HF bands, and the wired communication network may be connected via a network line such as a dedicated line. The data processing unit (120) may determine a transmission path by reflecting the type of data to be transmitted and the currently available communication means.

[0079] For example, target detection information can be transmitted using the wired communication network under normal conditions, and when the operation of the wired communication network is difficult, the same information can be transmitted by switching to the mobile communication network or the satellite communication network. Additionally, the satellite communication network can be used in a long-distance monitoring environment, while the wireless communication network or the mobile communication network can be used in a short-distance or mobile operation environment. Accordingly, the integrated interlocking device can transmit the same sensor information to an external system using different communication methods depending on the operating environment.

[0080] According to another embodiment of the present invention, the integrated interlocking device may be implemented in a shape in which a plurality of interlocking units (130) and a plurality of communication units (140) are housed together inside a single housing (110). The shape may be applied in an environment intended to simultaneously accommodate a plurality of surveillance and reconnaissance sensor systems (10) and a plurality of communication networks (20).

[0081] For example, a first linkage unit, a second linkage unit, a third linkage unit, a first communication unit, and a second communication unit may be arranged together inside the housing (110). In this case, the first linkage unit may be connected to a radar, the second linkage unit may be connected to an electro-optical / infrared camera, and the third linkage unit may be connected to a seismic sensor. Additionally, the first communication unit may be connected to a wired communication network, and the second communication unit may be connected to a mobile communication network or a satellite communication network. The data processing unit (120) may classify data input from each linkage unit and then distribute it to different communication units according to the target system or transmission priority.

[0082] According to this multi-embedded configuration, the integrated interlocking device can handle a multiple sensor-multiple network structure within a single enclosure, going beyond a single sensor-single network structure. Therefore, instead of deploying multiple separate independent devices depending on the field environment, the operator can manage multiple sensor inputs and multiple communication paths together within a single integrated interlocking device.

[0083] According to another embodiment of the present invention, the integrated interlocking device may be expanded by connecting a separate additional interlocking module (200) in addition to the basic shape. The additional interlocking module (200) may be connected to the integrated interlocking device through the connector part (150) and may further include one or more interlocking units (130) and / or one or more communication units (140).

[0084] For example, if the integrated linkage device of the basic shape is configured to handle one type of radar and one type of wired communication network, the additional linkage module (200) can be connected to add a serial linkage unit (132) for an electro-optical / infrared camera and a communication unit (140) for satellite communication. In this case, the data processing unit (120) may refer to a configuration file or device identification information again to reflect whether the additional linkage module (200) is connected, and may include the newly added linkage path and communication path in the operation configuration.

[0085] In addition, in a specific site, it can be operated with only the basic configuration, but if an additional surveillance and reconnaissance sensor system (10) is introduced, it can respond through the additional linkage module (200). Accordingly, the integrated linkage device can be structured to expand functions as needed, rather than excessively embedding all sensors and all communication functions from the beginning.

[0086] According to one embodiment of the present invention, software installed in the data processing unit (120) may be implemented to operate in accordance with the configuration file and the status of the actually installed linkage unit (130) and communication unit (140). The software may be provided to support variable sensor linkage and variable communication network connection, and may be configured to process different sensor and message specifications without large-scale program modifications.

[0087] For example, the data processing unit (120) may load a configuration file upon system startup and refer to the type, quantity, port arrangement, and connection priority of the currently installed linkage unit (130) and communication unit (140). Subsequently, the data processing unit (120) may configure the first sensor data to be input through the Ethernet linkage unit (131) and the second sensor data to be input through the serial linkage unit (132). Additionally, the data processing unit (120) may configure the first communication path to be a wired communication network and the second communication path to be a mobile communication network or a satellite communication network.

[0088] The above software may apply a multi-tactical data link message processing method using a markup language to process various linkage and communication messages. Accordingly, the data processing unit (120) may organize data received from the sensor into an internal representation format and then convert it into a message structure corresponding to a receiving target system or a selected communication path. For example, radar detection information may be converted into a transmission message centered on location information and target identification information, and metadata from an electro-optical / infrared camera may be converted into a message centered on image identification information and time information. The conversion may be adjusted through changes to a configuration file or message description rules.

[0089] According to one embodiment of the present invention, the integrated interlocking device basically transmits data using one communication network (20), but if a change in the state of the communication network in use occurs, another communication network may be used as a bypass path. The bypass operation may be performed based on the state information received by the data processing unit (120) from the communication unit (140) and the priority defined in the configuration file.

[0090] For example, the data processing unit (120) may be configured to use a wired communication network as the primary path during normal operation. Subsequently, if transmission through the wired communication network is not performed for a certain period of time or if the connection status information falls outside the set value range, the data processing unit (120) may select a mobile communication network as an alternative path. Additionally, if the use of the mobile communication network is also restricted, a satellite communication network or a wireless communication network may be selected as a subsequent path. During this switching process, the data processing unit (120) may retransmit the same sensor data by adding a different communication format or different transmission path information.

[0091] The above bypass operation is not limited to a single specific method. For example, switching from a wired network to a mobile network and switching from a mobile network to a satellite network may be performed under different operating conditions. Furthermore, the above bypass criteria may be set based on whether the line responds, whether transmission is successful, or device status information, in addition to whether there is a simple disconnection. However, the specific criteria values ​​may be adjusted according to the operating environment.

[0092] According to one integrated embodiment of the present invention, the integrated linkage device may be configured to simultaneously accommodate a radar, an electro-optical / infrared camera, and a seismic vibration sensor. In this case, the radar may be connected via an Ethernet linkage unit (131), the electro-optical / infrared camera may be connected via a serial linkage unit (132), and the seismic vibration sensor may be connected via a separate serial linkage unit (132) included in an additional linkage module (200). The data processing unit (120) may classify data received from each sensor by sensor type and convert it into data for transmission according to message processing rules defined in a configuration file.

[0093] The communication unit (140) may be configured to be simultaneously connected to a wired communication network and a mobile communication network, and a satellite communication function may be added through an additional linkage module (200). The data processing unit (120) normally transmits sensor information to the command and control / weapon system (30) via a wired communication network, but can be controlled to use a mobile communication network when the wired communication path is difficult to use, and to use a satellite communication network when the use of the mobile communication network is also restricted. Accordingly, the integrated linkage device can implement the input of multiple sensors, the selection of multiple communication networks, and a module expansion structure together within a single device system.

[0094] According to one embodiment of the present invention, the data processing unit (120) loads a configuration file when the system starts and can determine the operational configuration of the linkage unit (130) and the communication unit (140) by referring to items defined in the configuration file. The configuration file may include at least one of a sensor system identification item, an interface type item, a port or channel designation item, a message processing rule item, a transmission target system item, a communication network priority item, and an alternative path item in case of failure. Accordingly, the data processing unit (120) can operate to correspond to different surveillance and reconnaissance sensor systems (10) and different communication networks (20) according to the contents of the configuration file, even if the same hardware configuration is used.

[0095] For example, the sensor system identification item may specify which sensor among radar, electro-optical / infrared camera, radio wave receiving equipment, seismic vibration sensor, or infrared sensor is connected to which linkage unit (130). Additionally, the interface type item may specify whether the sensor is connected via an Ethernet linkage unit (131) or via a serial linkage unit (132). The port or channel designation item may include the actual port number, communication channel, or address information to which the sensor data is input, and the message processing rule item may specify a procedure for converting the received data into an internal processing format or a procedure for reconstructing it into a message format for external transmission.

[0096] Additionally, the communication network priority item can specify which communication network to use as the priority path and which to use as the auxiliary path when the integrated interlocking device can use multiple communication networks (20). The alternative path item can specify the order of the communication networks to be used next when it is difficult to use a specific communication network. For example, the configuration file can define a wired communication network as the first path, a mobile communication network as the second path, and a satellite communication network as the third path. Accordingly, the data processing unit (120) can reconstruct the transmission path by referring to the order defined in the configuration file when a change in the communication status occurs during actual operation.

[0097] According to one embodiment of the present invention, the data processing unit (120) may determine a processing path by reflecting the current status of the currently installed linkage unit (130) and communication unit (140) together with the contents of the configuration file, rather than unilaterally referencing only the configuration file. For example, when the system starts or when an additional linkage module (200) is connected, the data processing unit (120) may identify the type, quantity, port placement status, or activation status of the currently installed unit, and generate a valid processing configuration by comparing the identification result with the information defined in the configuration file.

[0098] For example, the above configuration file defines that a radar is connected to the first Ethernet linkage unit (131), but in the actual installation status, the first Ethernet linkage unit (131) may not exist or may be in a deactivated state. In this case, instead of applying the contents of the above configuration file as is, the data processing unit (120) may search for another linkage unit (130) that is currently available, or may reconfigure the operation configuration by temporarily excluding the input path corresponding to the sensor system. Conversely, if the additional linkage module (200) is newly connected and the second serial linkage unit (132) or the second communication unit (140) is added, the data processing unit (120) may reconfigure the input path and transmission path to include the added unit. Accordingly, the integrated linkage device may have a variable processing configuration that corresponds to changes in the actual installation status.

[0099] According to one embodiment of the present invention, the data processing unit (120) may apply message processing rules by reflecting the message structure for each sensor and the required format of the transmission target system, instead of transmitting data received from different surveillance and reconnaissance sensor systems (10) in batches. The message processing rules may be defined according to a multi-tactical data link message processing method using a markup language, and the rules may include at least one of an input field identification rule, an internal common field mapping rule, an output message configuration rule, and a message selection rule for each transmission target system.

[0100] The above message processing rules may include at least an input field identification rule, an internal common field mapping rule, an output message combination rule, and a message selection rule per transmission target system. For example, the input field identification rule may be defined to identify target identifier, distance, bearing, speed, and detection time fields in a detection message input from a radar, and the internal common field mapping rule may be defined to correspond the identified fields to target identification items, location items, motion items, and time items of an internal common structure. Additionally, the output message combination rule may be defined to selectively generate output messages for a command and control system or transmission message structures per communication network based on the internal common structure. Accordingly, the data processing unit (120) can respond to different sensor messages and different output message structures by updating some items of the message processing rules, instead of modifying individual program logic for each type of sensor.

[0101] For example, the radar data may include target identification information, distance information, bearing information, and detection time information, and the electro-optical / infrared camera data may include image identification information, shooting time information, and image status information. The data processing unit (120) may extract necessary fields from each sensor data, rearrange the fields into internal common items, and then convert them into an output message structure suitable for a command and control / weapon system (30) or a selected communication network (20). In this case, the conversion process may be performed by updating the message processing rules or the rule items of the configuration file, rather than by writing new separate program code for each type of sensor. Accordingly, the integrated interlocking device can adjust the processing structure even when sensor types are added or some message formats are changed.

[0102] According to one embodiment of the present invention, the data processing unit (120) can determine whether to bypass transmission by reflecting the status of the communication network (20) in use. The determination can be performed based on at least one of the following: whether transmission is successful, whether a response is received, the number of retries, whether a status signal is received, or whether a connection is maintained for a certain period of time.

[0103] When determining whether a bypass transmission is necessary, the data processing unit (120) first checks whether transmission is successful for the communication network currently in use, then checks whether a response is received within a set time interval, and subsequently checks whether link status information or wireless quality status values ​​are included in the normal range. If at least one of the above criteria falls outside a preset allowable range, the data processing unit (120) determines the current path as a degraded path, searches for a next-priority communication network defined in a configuration file, and then activates a communication unit (140) corresponding to the next-priority communication network to retransmit the same data or reconstructed data.

[0104] For example, the data processing unit (120) may be configured to use a wired communication network as the primary path. In this case, the data processing unit (120) may determine, as a first criterion, whether transmission retries have occurred more than a certain number of times, as a second criterion, whether a response message has been received within a set time interval, and as a third criterion, whether the link status information received from the communication unit (140) falls within the normal range. If at least one of the criteria does not satisfy a predetermined condition, the data processing unit (120) may determine that the status of the wired communication network currently in use has deteriorated and select the mobile communication network or the satellite communication network as an alternative path.

[0105] In addition, similar criteria may be applied even when the above mobile communication network is in use. For example, the data processing unit (120) may switch to using a satellite communication network or a wireless communication network instead of the mobile communication network if data transmission is not completed for a certain period of time or longer during transmission via the mobile communication network, if connection resetting occurs more than a preset number of times, or if a status value corresponding to wireless signal quality deviates from the standard range. Accordingly, the integrated interlocking device may have a structure that goes beyond merely listing communication network types and adjusts the actual operating path according to changes in communication status.

[0106] According to one embodiment of the present invention, the data processing unit (120) can reconfigure the transmission procedure after determining a bypass transmission. For example, when the data processing unit (120) detects a transmission failure using the first communication network, it checks the status of the communication unit (140) corresponding to the first communication network, searches for the next-priority communication network defined in the configuration file, and then activates the communication unit (140) corresponding to the next-priority communication network to transmit the same data or reconfigured data. In this process, the data processing unit (120) may reuse the already generated message as is, or readjust the message structure to match the protocol format of the next-priority communication network.

[0107] For example, if detection information that needs to be transmitted to the command and control / weapon system (30) is not transmitted through the first wired communication network, the data processing unit (120) may re-add a transmission header for a mobile communication network or a transmission field for a satellite communication network to the detection information and then re-transmit it through the mobile communication network or the satellite communication network. Additionally, the data processing unit (120) may record the fact that a bypass transmission occurred as an internal log or status message, or maintain the state of using the bypass path during subsequent transmission. Accordingly, the bypass transmission can be implemented not only as a temporary path change but also in the form of operating an alternative path for a certain period.

[0108] According to one embodiment of the present invention, when the additional linkage module (200) is connected through the connector part (150), the data processing unit (120) can reset the operation configuration by reflecting the linkage unit (130) or communication unit (140) included in the additional linkage module (200). For example, when the additional linkage module (200) is connected, the data processing unit (120) can read the identification information, type of included unit, port information, or activation status of the additional linkage module (200), and generate a new input path and a new transmission path by comparing them with the extension rule items defined in the configuration file.

[0109] The identification information of the additional linkage module (200) can be read based on at least one of a module identification signal transmitted through the connector part (150), stored device technical information, or an activation response message. For example, the data processing unit (120) can transmit a preset identification request signal after the additional linkage module (200) is connected, and receive, in response, the type of linkage unit included in the additional linkage module (200), the type of communication unit, available port information, and activation status information. The data processing unit (120) can generate a new input path and a new transmission path by comparing the received identification information with the extension rule item of the configuration file.

[0110] For example, the additional linkage module (200) may be connected to the integrated linkage device, which in the basic configuration only processed radar and wired communication networks, so that a serial linkage unit (132) for EO / IR sensors and a communication unit (140) for satellite communication may be added. In this case, the data processing unit (120) manages radar data as a first processing group and EO / IR data as a second processing group, and can select which communication network to use between the wired communication network and the satellite communication network depending on the type of data or the operating status. Accordingly, the connection of the additional linkage module (200) may not be limited to a simple port expansion, but may function as a structure that reflects both the expansion of input targets and the expansion of transmission paths.

[0111] A data processing unit (120) according to one embodiment of the present invention may be configured to perform protection operations based not only on internal temperature in an operating environment where a plurality of interlocking units (130), communication units (140), and additional interlocking modules (200) are combined inside a housing (110) or through a connector part (150), but also to calculate a thermal-electromagnetic stress index that reflects the module coupling state, heat accumulation state, and electromagnetic leakage state together, and to perform stepwise hardware protection control according to the calculated index.

[0112] The data processing unit (120) can first obtain a first determination factor that reflects the module coupling state. The first determination factor may include the number of additional interlocking modules (200) connected to the connector part (150) and a shielding opening ratio, which is the ratio of the effective opening area with reduced shielding continuity to the total shielding area of ​​the housing (110). Here, the shielding opening ratio is not calculated simply based on the number of ports, but can be calculated based on the actual area of ​​ports with removed shielding covers, connection parts with reduced shielding performance, or connector areas open to the outside. Accordingly, the data processing unit (120) can determine the basic load state of the housing (110) by reflecting both the number of modules coupled and the actual degree of reduced shielding continuity.

[0113] The data processing unit (120) may then obtain a second judgment factor that reflects the heat accumulation state. The second judgment factor may include at least one of the following: the duration of the temperature rise inside the housing (110), the heat recovery delay time required for the temperature inside the housing (110) to return to a preset normal range after reaching a reference maximum temperature, and the slope of the temperature drop curve. The heat recovery delay time may be calculated as the time required to return to a reference temperature range corresponding to the normal operating range from the point in time when the heat load is reduced, and the slope of the temperature drop curve may be calculated by comparing temperature values ​​at multiple points in time that are continuously measured. Accordingly, the data processing unit (120) can determine the heat accumulation state by reflecting not only the instantaneous temperature inside the housing (110) but also the degree of heat accumulation and the degree of heat discharge delay.

[0114] The data processing unit (120) may also obtain a third judgment factor reflecting the state of electromagnetic leakage. The third judgment factor may include the discontinuity of the ground path impedance before and after module coupling, the ratio of fine gaps in the connector part (150) or the housing (110) shielding gasket joint, and the residual time of electromagnetic energy in the internal cavity of the housing (110). The discontinuity of the ground path impedance may be obtained by measuring the reflection characteristics, impedance deviation rate, or degree of ground continuity degradation on the connector pin joint or the ground path. The ratio of fine gaps may be calculated as the ratio of an incomplete contact area exceeding a certain standard relative to the total joint length or total joint area, using the contact resistance distribution or leakage current distribution measured along the shielding gasket or joint. The residual time of electromagnetic energy may be calculated by measuring the attenuation curve after applying a reference pulse or an internal transmission signal through an electromagnetic sensing sensor placed inside the housing (110). For example, if the time required to attenuate below a reference electromagnetic field strength becomes longer than in a normal operating state, the data processing unit (120) may determine this as a sign of electromagnetic leakage or deterioration of shielding performance.

[0115] The data processing unit (120) may not simply evaluate the first judgment factor, the second judgment factor, and the third judgment factor independently, but may combine them stepwise based on physical causal relationships. Specifically, the data processing unit (120) may first set a reference stress value based on the number of additional linkage modules (200) and the shielding opening ratio. At this time, the reference stress value may increase as the number of modules and the shielding opening ratio increase; however, since there is a spatial saturation state and placement limit inside the housing (110), the increase may be set to gradually become gentle after a certain period. Subsequently, the data processing unit (120) may calculate the heat accumulation degree from the temperature rise duration and the heat return delay time, and add the heat accumulation degree to the reference stress value. At this time, the heat accumulation degree may be set as a value that reflects the number of heat sources inside the housing (110), the heat generation duration, and the degree of heat discharge delay.

[0116] Next, the data processing unit (120) can evaluate the ground path impedance discontinuity, the micro-air gap ratio, and the electromagnetic energy residual time as electromagnetic leakage factors. Since the electromagnetic leakage factors may cause a relatively large level of noise interference or deterioration of electromagnetic coupling at the moment they exceed a certain range, rather than a simple linear increase during the operation of the equipment, the data processing unit (120) may be configured to apply a non-linear additional weight to the cumulative score reflecting the reference stress value and the heat accumulation as the electromagnetic leakage factors increase. For example, if the micro-air gap ratio is less than the first leakage reference value, only a low level of correction weight may be applied, but if the micro-air gap ratio increases above the first leakage reference value and the ground path impedance discontinuity is also detected, a relatively high level of weight may be applied to the entire cumulative score. In addition, if the above electromagnetic energy residual time exceeds the reference decay time, it is determined that the electromagnetic energy remains for a long time in the cavity inside the housing (110), and the electromagnetic leakage-related weighting can be further increased.

[0117] The data processing unit (120) can perform stepwise protection operations by comparing the thermal-electromagnetic stress index calculated as above with a plurality of control thresholds. The plurality of control thresholds may include a first threshold, a second threshold, and a third threshold, and each threshold may be set based on a prior environment test, a module coupling test, a shielding performance test, and a history of communication anomalies. For example, if the thermal-electromagnetic stress index exceeds the first threshold, the data processing unit (120) may perform a throttling operation as a first step measure to limit the data packet throughput allocated to the additional linkage module (200) or the selected linkage unit (130). Here, the throttling operation is not limited to a reduction in the operating frequency of the processor, but may include operations to reduce the message processing allocation per unit time passing through the bus data communication line or to extend the packet transmission interval for a specific module.

[0118] Additionally, if the thermal-electromagnetic stress index exceeds a second threshold, the data processing unit (120) may, as a second-stage measure, control the rotational speed of the cooling fan upward and activate an auxiliary heat dissipation circuit or a heat exhaust auxiliary unit. Along with this, the data processing unit (120) may continuously re-evaluate whether the electromagnetic leakage factor continues to increase to determine whether simple thermal control alone is sufficient. Furthermore, if the thermal-electromagnetic stress index exceeds a third threshold, the data processing unit (120) may, as a third-stage measure, sequentially cut off the power supply to the most recently connected additional interlocking module (200) or a predefined lower priority module, or stop its function. Accordingly, the integrated interlocking device can protect higher priority modules from increased electromagnetic interference or excessive heat accumulation without stopping the entire system at once.

[0119] The data processing unit (120) may perform an exception handling procedure prior to performing the protection operation. For example, even if one of the multiple temperature sensors momentarily outputs an abnormally high temperature value, if the output value does not match the measurement values ​​of other temperature sensors, the ground path impedance state, the micro-air gap ratio, and the module coupling state, the data processing unit (120) may determine this as temporary sensor noise or disturbance and defer the step action for a certain hold time. During the hold time, the data processing unit (120) may be configured to cross-verify whether there is a change in adjacent sensor values, history values ​​from a previous point in time, and other judgment factors, and to perform the first to third step actions only when an abnormal state is simultaneously reconfirmed in multiple factors. Accordingly, the situation in which unnecessary module blocking occurs due to a false detection by a single sensor can be reduced.

[0120] As an embodiment of the present invention, a situation may be assumed in which two additional linkage modules (200) for an electro-optical camera are newly connected to a basic integrated linkage device. The data processing unit (120) can set a reference stress value by detecting an increase in the number of connections of the additional linkage modules (200) and an increase in the shielding opening ratio. Subsequently, as the modules are continuously operated for a certain period of time, the internal temperature of the housing (110) rises, and if the thermal recovery delay time to return to a normal range becomes longer than usual, the data processing unit (120) can increase the accumulated stress level by adding the thermal accumulation degree to the reference stress value. Subsequently, if the connection state of any one module becomes loose due to field vibration or repeated impact, the micro-air gap ratio increases, and the ground path impedance discontinuity can be detected together. Furthermore, if it is confirmed that the electromagnetic energy residual time in the internal cavity of the housing (110) is longer than the normal operating state, the data processing unit (120) determines this as a state where electromagnetic leakage is expanding and may assign a high additional weight to the accumulated stress level. If the calculated result exceeds a third threshold, the data processing unit (120) may prioritize cutting off the power supply to the additional interlocking module (200) where connection instability was detected in order to reduce the spread of communication instability in the entire system, and may send a warning message to the command and control system (30) or the administrator terminal.

[0121] In another embodiment, even if the number of modules is not large and the internal temperature is relatively low, if the fine air gap ratio and the ground path impedance discontinuity rate increase simultaneously while the shielding opening ratio increases, the data processing unit (120) can identify an increase in electromagnetic leakage that is difficult to detect by a simple temperature criterion alone at an early stage. In this case, the data processing unit (120) can perform a first or second stage measure first by reflecting a weight based on the electromagnetic leakage factor, even though the temperature has not reached the second thermal criterion. Accordingly, a situation where response may only begin after communication data distortion or sensor interference has fully developed in a single temperature criterion method can be controlled at an earlier point in time.

[0122] Each reference value, threshold value, and weight used in the above process 1 is not limited to fixed values. These values ​​may be set or updated based on the no-load state test, step-by-step module coupling test, shielding performance test, thermal recovery characteristic test performed during the initial setup of the device, and the history of abnormal occurrences accumulated during operation. For example, the reference value for the thermal recovery delay time may be set to the temperature recovery characteristic of the no-load normal state measured during system initialization as the initial value, and the judgment reference value for the fine air gap ratio or ground path impedance discontinuity may be set by referring to the reference profile obtained from repeated coupling tests and shielding performance degradation tests. Accordingly, the above process 1 may be implemented as an adaptive protection logic that reflects both the structural state inside the housing (110) and the operational history, rather than a simple single threshold response method.

[0123] As such, Process 1 of the present invention evaluates a plurality of independent physical factors in stages and performs hardware protection control using a thermal-electromagnetic stress index that combines the heat accumulation state and the electromagnetic leakage state, thereby enabling a more proactive response to situations such as coupling failure, shielding performance degradation, and increased electromagnetic interference that are difficult to detect in control methods that rely solely on simple internal temperature criteria. Accordingly, the integrated interlocking device can be controlled to maintain communication stability and device availability even under conditions where vibration, shock, temperature changes, and module expansion occur repeatedly, such as in a field environment.

[0124] According to one embodiment of the present invention, the thermal-electromagnetic stress index used in Process 1 can be calculated by combining the coupling state of the additional interlocking module, the shielding opening ratio, the heat accumulation state, and the electromagnetic leakage state in stages. The first, second, and third thresholds of the index are not set as arbitrary fixed values, but can be set based on test results reflecting the thermal behavior of the housing material, the section where shielding performance deteriorates, the section where ground continuity deteriorates, and the section where actual communication abnormalities occur. For example, through thermal flow analysis, structural vibration environment simulation, and electromagnetic leakage verification, the section where the internal housing temperature rise and electromagnetic leakage begin to affect communication stability and the section where actual protection control is required can be derived in stages.

[0125] In an exemplary simulation to verify the appropriate range of the above reference values, the first simulation assumes a normal state where the basic opening ratio score is 15 points, the heat accumulation score is 10 points, and no weighting related to electromagnetic leakage is applied. In this case, the final stress index can be calculated at a level of 25 points, and the hardware condition can be judged as a normal range with temperature stability and almost no electromagnetic leakage. In the second simulation, it assumes a state where the basic opening ratio score increases to 25 points and the heat accumulation score increases to 20 points; in this case, the final index rises to a level of 45 points, but it can still be evaluated as a state where operation is possible within an acceptable range. In the third simulation, it assumes a state where the basic opening ratio score increases to 35 points and the heat accumulation score increases to 30 points; the final index reaches a level of 65 points, which can be interpreted as a state just before sustained heat generation and communication packet delay occur.

[0126] In the fourth simulation, a state combining a basic opening rate score of 35 points and a heat accumulation score of 38 points can be assumed. In this case, the final index can be calculated at a level of 73 points, which can be used as an example of a section where throttling control can be initiated around the first threshold of 70 points. In the fifth simulation, a combination of a basic opening rate score of 45 points and a heat accumulation score of 45 points can be assumed, and the final index can be calculated at a level of 90 points. The above section can be understood as an example of a second threshold section where an increase in the rotational speed of the cooling fan and auxiliary heat dissipation operation are required.

[0127] Meanwhile, situations where the electromagnetic leakage factor is amplified can also be examined separately. In the 6th simulation, a case can be assumed where the load is relatively low with a basic aperture score of 15 points and a heat accumulation score of 15 points, but an additional weighting of level 1.5 is reflected due to the occurrence of micro-air gaps. In this case, the final index can be calculated at the level of 45 points, and it can be interpreted as a state where minor electromagnetic noise is detected despite not generating much heat. In the 7th simulation, a case can be assumed where the basic aperture score of 25 points, a heat accumulation score of 30 points, and the same weighting of level 1.5 act together, and the final index reaches approximately 82 points, which can serve as an example of a section where interference between adjacent modules begins. In the 8th simulation, a case can be assumed where a weighting of level 1.8 is applied by reflecting both impedance anomalies and an increase in electromagnetic residual time in a state with a basic aperture score of 35 points and a heat accumulation score of 35 points. In this case, the final index can rise to about 126 points, which can be seen as an example of a state requiring higher-level protection control due to exceeding the third threshold.

[0128] Additionally, in the 9th simulation, a weighting level of 2.0 can be applied by assuming a composite failure state in which a basic aperture score of 45 points, a heat accumulation score of 45 points, and air gap expansion and impedance abnormalities are simultaneously superimposed. In this case, the final index can be calculated at a level of 180 points, which may indicate a state requiring active protective measures such as module power cutoff. In the 10th simulation, even though the thermal load is not relatively high with a basic aperture score of 25 points and a heat accumulation score of 20 points, the final index can reach a level of 90 points when a composite failure weighting level of 2.0 is applied. The above examples can be used to demonstrate that immediate action may be required due to electromagnetic leakage alone, even if the heat generation level is relatively low.

[0129] Verification simulations may also be performed to compare the effects of the first, second, and third thresholds set as described above. For example, when multiple modules are combined at the initial stage of operation but the external environment is stable, both the simple temperature-based control method of the comparative example and the composite index-based control method of the present invention can maintain a normal operating state. However, in the mid-stage, where micro-air gaps occur due to vibration accumulation as operation time progresses, the simple temperature-based control method fails to detect this and thus cannot take separate measures, whereas the method of the present invention can proactively perform first-stage throttling by reflecting electromagnetic leakage weights. Subsequently, in the late stage, when impedance discontinuities overlap, the simple temperature-based control method reaches a communication shutdown only after high heat is generated, whereas the method of the present invention can increase the possibility of maintaining the entire communication network by selectively blocking abnormal modules in the third stage. Accordingly, the above-mentioned process 1 can be utilized to confirm that it is possible to respond at an earlier stage to situations where electromagnetic leakage expands, which are difficult to detect with a single temperature criterion alone.

[0130] A data processing unit (120) according to one embodiment of the present invention may be configured to perform a detection reliability evaluation process that reflects physical conditions favorable for target detection and external environmental attenuation conditions that hinder target detection, rather than relying solely on a simple data format error rate or a single signal strength, in order to determine the reliability level of target detection data collected from a plurality of heterogeneous sensors, such as radar, electro-optical camera, infrared camera, and seismic motion sensor. The process 2 may be configured to form an initial reliability based on the degree of thermal separation between the target and the background and the possibility of verifying motion between sensors, and then determine a final reliability by correcting the initial reliability by reflecting environmental and structural factors such as condensation, scattering, polarization mismatch, and sensor axis alignment error.

[0131] The data processing unit (120) can first obtain a first judgment factor for forming initial reliability. The first judgment factor may include thermal contrast between the target and the background and the degree of motion agreement between heterogeneous sensors. The thermal contrast can be calculated as the difference between the average temperature of a group of pixels in the target area and the average temperature of a group of pixels in the background area within an image frame acquired from a thermal imaging camera or an infrared camera. For example, the thermal contrast may increase as the degree to which the average temperature of the target area is higher or lower than that of the background area becomes clearer. The degree of motion agreement can be calculated as the correlation or agreement between a Doppler change pattern, velocity change pattern, or distance change pattern acquired from a radar and a time-dependent response pattern acquired from a seismic motion sensor or other auxiliary sensors. In this case, the degree of motion agreement can be calculated after removing the background vibration baseline or excluding reference waveforms corresponding to environmental factors other than the target, such as waves, wind tunnels, or vehicle vibrations. Accordingly, the data processing unit (120) can determine in an initial stage whether different sensors are detecting the movement of the same target in a consistent manner.

[0132] The data processing unit (120) may then obtain a second judgment factor reflecting environmental attenuation. The second judgment factor may include a condensation margin deficit based on the difference between the lens temperature and the dew point temperature, a scattering attenuation coefficient due to rain, fog, sea fog, snow, or moisture particles in the atmosphere, and a loss of transmission / reception polarization mismatch of a radar-type sensor. The condensation margin deficit may be calculated by comparing the dew point temperature, calculated based on the ambient temperature and relative humidity, with the temperature measured by a temperature sensor installed on the lens surface or adjacent to the lens. For example, it may be determined that the condensation margin deficit increases in the range where the lens surface temperature approaches or is lower than the dew point temperature. The scattering attenuation coefficient may be calculated based on moisture density, visibility reduction, or optical attenuation obtained from a forward moisture detection sensor, a visibility measuring device, a humidity sensor, or an optical attenuation measuring unit. The above polarization mismatch loss can be calculated as a loss value corresponding to the difference between the polarization direction of the transmitted wave and the polarization direction of the reflected wave or received wave. Accordingly, the data processing unit (120) can quantitatively reflect the attenuation effect that the actual external environment in which the sensor is placed has on the detection performance. Since fog and rain can limit the infrared signal transmission distance and polarization mismatch can reduce the reception strength, the above variables can function as environmental attenuation factors.

[0133] The data processing unit (120) may also obtain a third judgment factor that reflects the structural alignment state. The third judgment factor may include a sensor axis alignment error between the radar center axis and the optical sensor center axis. The sensor axis alignment error may be obtained through a zeroing procedure performed during the initial installation of the system, a periodic correction procedure, or an alignment verification procedure using a reference target. For example, the alignment error can be calculated by measuring the spatial angle difference between the direction the radar center axis points and the direction the optical lens center axis points. As the alignment error increases, the common detection area between the radar detection direction and the optical imaging direction decreases, and the possibility of mutual verification for the same target may also decrease. Therefore, the data processing unit (120) may reflect the alignment error as a separate deduction factor.

[0134] The data processing unit (120) can combine the first judgment factor, the second judgment factor, and the third judgment factor stepwise according to physical causal relationships. First, the data processing unit (120) can calculate an initial reliability using thermal contrast and motion matching. At this time, the initial reliability may increase as the thermal contrast increases, but the rate of increase in the initial reliability may be set to gradually become gentler after a certain interval. This is because while conditions favorable for detection may be formed as the thermal distinction between the target and the background becomes clearer, an increase in thermal contrast exceeding a certain level may not always lead to a reliability increase at the same rate. Additionally, the higher the motion matching, the more the data processing unit (120) determines that multiple sensors are detecting the same physical target movement, thereby further increasing the initial reliability.

[0135] Subsequently, the data processing unit (120) may perform an environmental attenuation correction step for the initial reliability. Specifically, if the condensation margin deficit increases, the scattering attenuation coefficient increases, or the polarization mismatch loss increases, the data processing unit (120) may correct the initial reliability by subtracting it. For example, if the condensation margin deficit is within a reference range and the scattering attenuation coefficient is low, the initial reliability may be maintained or reduced only slightly; however, if the condensation margin deficit enters a condensation risk zone and the scattering attenuation coefficient increases simultaneously, a relatively large reduction correction may be applied to the initial reliability as a whole. Since the polarization mismatch loss can act as a separate attenuation term reflecting the decrease in reception reliability of the radar-type sensor, the data processing unit (120) may apply additional deductions if the polarization mismatch loss exceeds a reference loss value. Accordingly, the data processing unit (120) can lower the final reliability by reflecting the deterioration of the external environment or propagation conditions, even if the target signal is strongly observed.

[0136] The data processing unit (120) may perform a structural correction step for sensor axis alignment error separately from the environmental attenuation correction. As the sensor axis alignment error increases, the data processing unit (120) may expand the deduction range for the initial reliability or the intermediate reliability reflecting the environmental attenuation. Additionally, if the alignment error exceeds a preset allowable range, the data processing unit (120) may be configured to classify the detection data into a lowest grade candidate group or convert it into a separate re-verification target group, instead of immediately discarding the data. The allowable range may be set based on the minimum overlap margin at which the radar beam width and the camera field of view intersect to form a common detection area. Accordingly, the data processing unit (120) can distinguish and process alignment deviations caused by temporary installation errors or platform oscillations from structural misalignment.

[0137] The data processing unit (120) can control subsequent operations by comparing the final reliability determined as above with a plurality of reliability level intervals. The reliability level intervals may include a high reliability level, an intermediate reliability level, and a lowest reliability level candidate group, and each reliability level interval may be established based on the thermal contrast distribution, weather attenuation distribution, polarization loss distribution, alignment error distribution, and false positive occurrence history obtained in a prior test environment. For example, if the final reliability is determined to be a high reliability level, the data processing unit (120) can classify the corresponding target information as priority transmission target data and immediately transmit it to the command and control system (30) or weapon system. If the final reliability is determined to be an intermediate reliability level, the data processing unit (120) can classify the corresponding target information as auxiliary verification data and perform a request for reconfirmation to adjacent surveillance and reconnaissance assets or other sensor systems. If the above final reliability is classified as a lowest-grade candidate group, the data processing unit (120) may control the data to be immediately excluded from the target for providing strike specifications and to display a separate warning on the operator screen or as a low-priority target. Here, the lowest-grade candidate group does not mean permanent disposal of the data, but may include a logical waiting state that suspends the immediate provision of specifications for the target until subsequent identical target data is judged to have normal reliability for a preset number of consecutive times.

[0138] The data processing unit (120) can perform an exception processing procedure to distinguish between temporary disturbances and structural environmental deterioration. For example, even if the scattering attenuation coefficient rises sharply for a short period, if the humidity change, visibility change, and attenuation trend of adjacent environmental sensors do not simultaneously support this, the data processing unit (120) may determine this as temporary lens contamination, momentary disturbance, or one-time optical noise and suspend immediate reduction of the final reliability. During the suspension period, the data processing unit (120) checks whether there is a simultaneous change in the scattering attenuation coefficient, condensation margin deficit, and polarization mismatch loss remeasured at multiple points in time, and performs full reliability downward correction only if multiple factors continuously deteriorate. Accordingly, situations where target information is excessively undervalued due to temporary disturbances can be reduced.

[0139] As an embodiment of the present invention, a situation may be assumed in which an electro-optical camera and a radar simultaneously detect a small vessel target in a coastal surveillance environment. The data processing unit (120) may first set the initial reliability of the target to a high level if it detects that the tropical contrast of the small vessel is sufficiently high compared to the surrounding sea surface background, and if it determines that the degree of motion agreement between the velocity change pattern acquired from the radar and the time-dependent response pattern acquired from the seismic motion sensor or auxiliary vibration sensor is high. Subsequently, as the sea fog thickens and the moisture density increases, the scattering attenuation coefficient rises, and as the lens surface temperature approaches the dew point temperature, the condensation margin deficit may also increase. Additionally, if polarization mismatch loss increases along with sea surface reflection or changes in the surrounding medium, the data processing unit (120) may perform a plurality of attenuation corrections on the initial reliability to lower the final reliability of the target to an intermediate grade or a lowest grade candidate group. In this case, the target may be excluded from the immediate target for strike data transmission and may be converted into an auxiliary tracking target or a target for reconfirmation.

[0140] In another embodiment, even if the thermal signal of the target itself is sufficiently high and the radar reflection is also stably detected, if the sensor axis alignment error repeatedly exceeds the allowable range, the data processing unit (120) may classify the final reliability of the target as a candidate for the lowest grade. This is because the possibility of mutual verification of the target detection results may be reduced when the radar and the optical sensor cannot observe the same spatial area with sufficient overlap. In this case, the data processing unit (120) may output a warning to the operator that alignment recalibration is required and allow the target information to undergo a separate re-verification procedure.

[0141] Each reference value, allowable range, and grade interval used in Process 2 above is not limited to fixed values. These values ​​may be set or updated based on zero-point alignment tests, weather simulation tests, lens condensation tests, polarization loss tests performed during the initial setup of the device, and the history of false positives and false negatives accumulated during operation. For example, the reference value for the condensation margin deficit may be set based on the interval where the difference between the lens surface temperature and the dew point temperature significantly causes image quality degradation of the equipment, and the allowable range for sensor axis alignment error may be set based on the minimum geometric overlap condition where the common detection area of ​​the sensors is maintained. Additionally, the interval values ​​for the high-reliability grade, medium-reliability grade, and lowest-reliability grade candidate group may be corrected by comparing them with target judgment results accumulated in actual operation scenarios.

[0142] As such, Process 2 of the present invention does not evaluate target data acquired from heterogeneous sensors based on simple signal strength or a single error rate, but rather reflects condensation, scattering, polarization mismatch, and alignment error in stages on the initial reliability formed by thermal contrast and motion consistency, thereby structurally reflecting the impact of actual external environmental constraints on target detection. Accordingly, the integrated interlocking device can select information with a high probability of distortion even in field environments where fog, rain, sea fog, temperature changes, and installation errors occur repeatedly, and can more stably adjust the level of utilization of target information transmitted to the command and control system (30) or weapon system.

[0143] According to one embodiment of the present invention, the final detection reliability used in process 2 can be calculated by stepwise combining an initial positive score formed by thermal contrast and motion matching, and subtraction or deduction factors assigned by condensation margin deficit, scattering attenuation coefficient, polarization mismatch loss, and sensor axis alignment error. The reliability grade range can be set based on prior environmental tests, condensation tests, fog and sea fog condition simulation tests, alignment error tests, and actual false positive and false negative history.

[0144] In an exemplary simulation to verify the appropriate range of the above reliability grade, the first simulation assumes a normal state where the initial positive score is high at the level of 90 points, the environmental attenuation score is at the level of 5 points, and no alignment error deduction multiplier is applied. In this case, the final reliability can be calculated at the level of approximately 85 points, and this can serve as an example indicating a high identification state where image and radar information match well together. In the second simulation, a case where the initial positive score is 80 points and the environmental attenuation score is 10 points can be assumed, and the final reliability is maintained at the level of 70 points, which can be evaluated as a range where a good identification state is still possible. In the third simulation, a case where an environmental attenuation score of 30 points is reflected for the initial positive score of 90 points can be assumed, and the final reliability is lowered to the level of approximately 60 points, which can be interpreted as a state where contour identification is possible but auxiliary verification is required.

[0145] In the fourth simulation, a normal alignment state can be assumed where an initial positive score of 70 points and an environmental attenuation score of 25 points are combined. In this case, the final confidence level can be calculated at 45 points, which can be used as an example value to set a boundary interval between the middle and lowest grade candidate groups. In the fifth simulation, a case where an environmental attenuation score of 40 points is applied to an initial positive score of 60 points can be assumed, and the final confidence level is lowered to 20 points, which can serve as an example of a low-confidence state where identifiability is significantly reduced.

[0146] Cases involving alignment errors may also be examined separately. In the 6th simulation, it can be assumed that an initial positive score of 90 points, an environmental damping score of 10 points, and an alignment error deduction multiplier of 1.5 are applied. In this case, the final reliability may be lowered to approximately 53 points, which can be viewed as an example of a state where the coordinate correction margin is reduced due to a decrease in axis alignment. In the 7th simulation, it can be assumed that an initial positive score of 80 points, an environmental damping score of 20 points, and a deduction multiplier of 1.8 are applied, and the final reliability is lowered to approximately 33 points, which can be used to explain a state where the process switches to a re-verification procedure rather than providing impact specifications.

[0147] The impact of adverse weather conditions can also be examined as an example. In the 8th simulation, it can be assumed that even if an initial positive score of 90 is secured, the environmental attenuation score increases to the level of 50 due to dense fog or sea fog. In this case, the final reliability may drop to the level of approximately 40, which may serve as an example indicating a state where the reliability of optical-radar fusion identification is significantly degraded. In the 9th simulation, it can be assumed that an initial positive score of 70, an environmental attenuation score of 45, and an alignment error deduction multiplier of 1.5 are applied simultaneously, and the final reliability drops to the level of approximately 16, which may be classified as a state requiring practical re-verification or a low-priority target. In the 10th simulation, it can be assumed that an initial positive score of 60, an environmental attenuation score of 10, and a severe alignment error deduction multiplier of 2.0 are applied. In this case, the final reliability can be evaluated at a level of about 25 points, and it can be used as an example of a state where the provision of immediate specifications is withheld until sensor calibration or realignment is completed.

[0148] The effectiveness of the reliability grade intervals set as described above can be verified through comparative simulations. For example, when the thermal signal of a target is sufficiently high under clear weather and normal alignment conditions, both the simple signal-based evaluation method and the method of the present invention can classify the target as a priority transmission target. However, in situations where lens condensation begins to occur, the simple signal-based evaluation can prioritize transmission based solely on the thermal signal intensity of the target, whereas the method of the present invention can downgrade the target to an intermediate grade or a re-verification target grade by reflecting both the condensation margin deficit and scattering attenuation. Furthermore, when dense sea fog and polarization loss increase simultaneously, the simple signal-based evaluation may mistake diffusely reflected signals for actual targets, whereas the method of the present invention can evaluate the final reliability to a low level to withhold the provision of immediate strike specifications or switch the target to a re-verification target. Accordingly, Process 2 can be utilized to more stably adjust the priority of target information with a high probability of distortion compared to the simple signal-based evaluation method, which does not reflect physical environmental constraints.

[0149] A data processing unit (120) according to one embodiment of the present invention may be configured to perform a dynamic direction and output control process that reflects the power survival status of the device and the physical attenuation status of the propagation path, rather than determining the transmission output based solely on a simple network occupancy rate or battery remaining value during the process in which the communication unit (140) transmits and receives data with a command and control system (30) or a weapon system. The above process 3 is intended to reduce power consumption caused by unnecessary high-output transmission in field environments, mobile environments, and long-term operation environments, and to proactively respond to the device instability state caused by voltage drop.

[0150] The data processing unit (120) may first obtain a first determination factor that reflects the power state. The first determination factor may include remaining battery energy, survival threshold energy for maintaining minimum function of the system, battery internal resistance, and voltage drop rate at the moment of transmission initiation. The remaining battery energy may be obtained through a battery management circuit, and the survival threshold energy may be pre-set as a reference energy required to maintain minimum location reporting, status transmission, and control signal reception. Additionally, the battery internal resistance may be calculated based on voltage and current changes before and after load application, and the voltage drop rate may be calculated using a voltage decrease trend measured during a short time interval when a transmission amplifier or high-power communication circuit is activated.

[0151] The data processing unit (120) can calculate the current effective power state based on the first judgment factor. Here, the effective power state may not be a simple percentage of remaining battery capacity, but a composite state value representing a power margin usable for actual transmission, which is calculated by subtracting the survival threshold energy from the remaining battery energy and reflecting a power drop correction value derived from the battery internal resistance and the voltage drop rate. Accordingly, the data processing unit (120) can identify that even if a certain level of remaining battery capacity is left, the state is not suitable for actual high-power transmission if the battery internal resistance increases or the voltage drop rate increases.

[0152] The data processing unit (120) may then obtain a second judgment factor that reflects the attenuation and directional state of the propagation path. The second judgment factor may include the first Fresnel zone shielding rate of the communication path, the polarization mismatch loss between the transmitting and receiving antennas, the yaw direction fine oscillation dispersion of the platform, and the wavelength of the communication network in use. The first Fresnel zone shielding rate may be calculated as the ratio of the main path volume of the propagation between the two points occupied by terrain features or obstacles, based on the location of the integrated interlocking device and the location of the command and control system (30) or relay base. The polarization mismatch loss may be calculated as a loss value resulting from the difference between the transmission polarization direction and the reception polarization direction or the reflected wave polarization direction. The yaw direction fine oscillation dispersion may be calculated as the dispersion value of the angular oscillation over time obtained through an inertial measurement unit or attitude sensor. The wavelength may be converted into and reflected as a physical wavelength value corresponding to the frequency band currently in use.

[0153] The data processing unit (120) may perform a stepwise processing procedure that prioritizes securing system survivability, rather than summing the effective power state and the second judgment factor in a one-dimensional manner. Specifically, the data processing unit (120) may first compare the effective power state with the survival threshold criterion. If the effective power state sufficiently exceeds the reference range, it is determined to be in a state capable of normal transmission, and if the effective power state approaches the reference range or decreases below it, it is determined to be in a state of reduced power survivability. At this time, if the effective power state reaches or falls below the first power limit criterion, the data processing unit (120) may control the system to block high-power transmission or immediately switch to a minimum survival communication mode instead of gradually performing output attenuation. This is because if additional high-power transmission is continued while the battery internal resistance is increased, the possibility of overall power instability or restarting of the device may increase.

[0154] The above-mentioned minimum survival communication mode may include an operational state reconfigured to stop the transmission of large volume video data, high-resolution radar track data, or continuous raw sensor streams, and to transmit only essential information necessary for mission continuation with a relatively small amount of transmission, such as location coordinates, device status codes, alarm flags, and short text-based target messages. When entering the minimum survival communication mode, the data processing unit (120) may control to limit the supply voltage applied to the transmission amplifier, rearrange packet priorities of the data link layer, and suspend the transmission of non-essential data channels.

[0155] On the other hand, if it is determined that normal transmission is possible because the above effective power state is stable, the data processing unit (120) may enter a radio environment attenuation evaluation step using the second judgment factor. The data processing unit (120) can determine whether the current transmission output is excessive compared to the actual arrival efficiency by evaluating the first Fresnel zone shielding rate, polarization mismatch loss, and the relative influence of yaw direction micro-fluctuations on wavelength. For example, as the first Fresnel zone shielding rate increases, it can be determined that the main radio path is partially blocked by terrain features, and as the polarization mismatch loss increases, it can be determined that the alignment state between antennas has deteriorated. In addition, if the yaw direction micro-fluctuation dispersion value increases above a certain level, the influence of directional error may be greater in communication networks with shorter wavelengths even with the same angle of shaking; therefore, the data processing unit (120) may reflect the combination of the wavelength length and the yaw direction micro-fluctuation together.

[0156] The data processing unit (120) may be configured to expand the downward range of the transmission output as the radio wave environment attenuation factors increase. However, the downward adjustment of the output is not limited to simple linear attenuation; it may be configured to be adjusted relatively sensitively at the beginning of the increase in the attenuation factor, and then gradually become gentler after exceeding a certain range. Accordingly, the data processing unit (120) can control the transmission output in a way that avoids excessive transmission suppression in the case of minor environmental deterioration and reduces wasted transmission power in the case of accumulated significant radio wave environment degradation. For example, if the first Fresnel zone shielding rate is less than the reference shielding rate and the polarization mismatch loss is also low, the transmission output may be maintained or adjusted only slightly; however, if the shielding rate and the polarization mismatch loss increase simultaneously and expand to include the yaw direction fine fluctuation, the transmission output may be down-adjusted to an intermediate or low-output level.

[0157] The data processing unit (120) can perform a communication network switching procedure according to the effective power state or the radio wave environment attenuation state. For example, if it is determined that the effective power state has deteriorated and it is difficult to continue operating the currently used high-power wireless communication network, the data processing unit (120) can control the transmission path to be switched to a mobile communication network, a wired communication network, or a communication network in an alternative frequency band capable of relatively low-power transmission. In addition, even if it is determined that the reach efficiency of the wireless radio wave path has significantly decreased due to the high shielding rate of the first Fresnel zone, the data processing unit (120) can control the path to search for an alternative path or delay the timing of data transmission instead of maintaining the current communication network. Accordingly, the integrated interlocking device can adjust the balance between power consumption and communication stability not only by increasing or decreasing output but also by switching the transmission path itself.

[0158] The data processing unit (120) can also perform an exception handling procedure for cases where specific environmental factors change rapidly in an instant. For example, when a vehicle passes over a large bump or is subjected to an external impact in an instant, the yaw direction fine fluctuation dispersion value may be measured to be very large. In this case, the data processing unit (120) may not immediately change the transmission output significantly based on the fluctuation measurement value at a single point in time, but may use the refined fluctuation value as a control input value after performing a moving average or similar filter processing on multiple fluctuation measurements collected during a recently set time interval. In addition, the first Fresnel zone shielding rate or the polarization mismatch loss may also not be determined based on a single measurement value alone, but may reflect the average value or trend value of multiple points in time. Accordingly, the data processing unit (120) can reduce situations where the transmission output fluctuates excessively due to temporary disturbances.

[0159] As an embodiment of the present invention, a situation can be assumed in which an integrated interlocking device mounted on a vehicle transmits monitoring data to a command and control system (30) while in operation. In the initial stages of operation, since flat terrain and sufficient battery conditions are maintained, the data processing unit (120) can determine the effective power condition to be at a high level and maintain a normal transmission state. Subsequently, as the vehicle enters mountainous terrain, the first Fresnel zone shielding rate increases, and if the yaw direction fine fluctuation dispersion value increases due to driving on unpaved roads, the data processing unit (120) can determine that the currently used high-frequency communication network is more sensitive to directional errors due to its short wavelength characteristics and can gradually lower the transmission output. At the same time, if the shielding rate rises above a certain level, control can be exercised to search for an alternative communication network instead of maintaining the current wireless path.

[0160] As another embodiment, it can be assumed that prolonged operation in a low-temperature environment causes the remaining battery charge to decrease and the internal resistance of the battery to increase. In this state, if a load is applied to the transmission amplifier for transmitting large-capacity video data, the voltage drop rate may increase significantly compared to normal. Even if the remaining battery charge has not been completely depleted, the data processing unit (120) may determine that the effective power state, reflecting the internal resistance and the voltage drop rate, is approaching the survival threshold. In this case, the data processing unit (120) may not continue high-output video transmission but immediately switch to the minimum survival communication mode to transmit only core coordinate information and status information. Accordingly, the possibility of the entire device entering an unstable state during high-load transmission can be reduced.

[0161] Each reference value, allowable range, and control interval used in the above process 3 is not limited to fixed values. These values ​​may be set or updated based on battery load tests, amplifier driving tests, low-temperature and high-temperature environment tests, terrain simulation propagation tests, and actual operational history performed during the initial setup of the device. For example, the survival threshold energy may be set based on the minimum energy profile required to maintain location reporting and status message transmission for a certain period of time, and the aging reference value for the battery internal resistance may be set by referring to a reference profile obtained from repeated charge-discharge tests or low-temperature load tests. In addition, the allowable range of the first Fresnel zone shielding rate and the attenuation reference value for polarization mismatch loss may be set based on the results of analyzing the correspondence between the communication success rate and the packet loss rate. The reference value for the yaw direction fine fluctuation dispersion may also be set differently depending on the wavelength and antenna beam width of the communication network in use.

[0162] As such, Process 3 of the present invention prioritizes evaluating the effective power state indicating the actual transmission capability of the battery, and subsequently controls the transmission output, transmission mode, and transmission path in stages by reflecting the attenuation and directionality of the propagation path, thereby enabling proactive response to signs of power instability and deterioration of the propagation environment that are difficult to detect in output control methods based on simple battery remaining capacity or simple distance. Accordingly, the integrated interlocking device can be controlled to maintain core communication functions even under conditions where power and propagation conditions change repeatedly, such as in mountainous terrain, mobile operation, low-temperature environments, and long-term operation environments.

[0163] According to one embodiment of the present invention, the active power state used in process 3 can be defined as a composite state value calculated by reflecting the remaining battery energy, survival threshold energy, battery internal resistance, and the voltage drop rate at the moment of transmission initiation. Additionally, the transmission output adjustment interval can be set based on test results reflecting the first Fresnel zone shielding rate, polarization mismatch loss, and the relative influence of yaw micro-fluctuations with respect to wavelength. The reference values ​​can be understood as embodiment values ​​set by synthesizing the minimum guaranteed voltage on the hardware datasheet, battery load test results, voltage collapse history under low temperature and aging conditions, and propagation path test results.

[0164] In an exemplary simulation to verify the appropriate range of the above-mentioned survival power section and output control section, the first simulation assumes a normal state where the surface area battery charge is at the 90% level and both internal resistance and voltage drop rate are low. In this case, the effective power state can be evaluated as having a sufficient margin of 85%, and the communication unit can stably perform high-speed transmission at maximum output. In the second simulation, a case can be assumed where the surface area battery charge is 50%, the internal resistance is within the normal range, and the voltage drop rate during transmission is low. In this case, the effective power state can be evaluated as approximately 40%, and it can be viewed as a general operating section where stable data transmission is possible.

[0165] In the third simulation, a case can be assumed where the surface area battery charge decreases to 20%, the internal resistance increases due to aging, and the voltage drop rate also increases. In this case, the active power state may drop to a warning range of approximately 5%, and this range can be used as an example of a boundary where output down-adjustment or data priority reallocation begins. In the fourth simulation, a case can be assumed where the surface area battery charge is 15%, the internal resistance increases significantly, and the voltage drop rate appears very high. In this case, the active power state can be evaluated as an imminent depletion range of 1%, and this can serve as an example of a state where the risk of voltage collapse significantly increases if high-capacity transmission continues. In the fifth simulation, a case can be assumed where the surface area battery charge is only 12%, and both the internal resistance and the voltage drop rate are extreme. In this case, the active power state can be evaluated as a negative range, and since a device power instability state may occur simultaneously with the initiation of high-output transmission, this can serve as an example where switching to a survival communication mode or blocking transmission is required.

[0166] Cases regarding low-temperature environments and abnormal battery conditions can also be examined as examples. In the 6th simulation, a case can be assumed where, even if the surface area of ​​the battery remains at the 30% level, the internal resistance increases due to the low temperature and the voltage drop rate appears very high. In this case, the effective power state drops to the 4% level, which can be used to explain a state where the actual discharge margin is insufficient compared to the displayed remaining capacity value. In the 7th simulation, a case can be assumed where, even though the surface area of ​​the battery remains at the 25% level, the effective power state reaches the boundary range of 0% due to the low temperature and increased internal resistance. In this case, high-power transmission is difficult, and it can serve as an example of a state where only low-capacity data transmission in the minimum survival communication mode can be maintained. In the 8th simulation, a separate exceptional case can be assumed where, even though the surface area of ​​the battery remains at the 80% level, the voltage drop rate appears abnormally large due to an internal abnormal state. In this case, the active power state can be evaluated as a negative value, and the above example can serve as an instance where the control logic proactively identifies an abnormal battery state that is difficult to identify solely by the remaining battery level display value. In the 9th simulation, a case can be assumed where the surface area battery level is 18%, the internal resistance is within the normal range, and the voltage drop rate is at an intermediate level. In this case, the active power state can be evaluated as approximately 12%, and the low-capacity data can be interpreted as being in a state where transmission is limited. In the 10th simulation, a case can be assumed where the surface area battery level is 14%, the internal resistance is in an aged state, and the voltage drop rate is high. In this case, the active power state can be evaluated as a limit range of 1% to 2%, and can be used as an example of a survival boundary state where only core text information can be continuously transmitted.

[0167] The effectiveness of the active power state criteria and survival communication mode switching criteria set as described above can be verified through comparative simulation. For example, if high-resolution video data is to be transmitted while the surface battery level is displayed as 40% and the internal resistance is high, a simple remaining capacity-based control method may accelerate remaining capacity consumption and voltage drop by continuing transmission. On the other hand, the method of the present invention can reduce the rapid deterioration of remaining energy by first evaluating the active power state and lowering the transmission output or lightweighting the data format. Furthermore, when transmitting large-capacity video data while the surface battery level is 15% and the voltage drop rate is high, a simple remaining capacity-based control method may cause the entire system to shut down due to voltage collapse during transmission, whereas the method of the present invention can proactively detect the deterioration of the active power state, stop video transmission, and switch to survival communication mode to transmit only key coordinate information. Furthermore, even in situations where only coordinate text data is transmitted in extreme low-temperature environments, a method based solely on a simple remaining capacity display value may not adequately reflect the risk of restart or shutdown, whereas the method of the present invention can be utilized to more proactively identify a section where survival communication can be maintained, albeit limitedly, by reflecting both internal resistance and voltage drop rate. Accordingly, the above process 3 can contribute to maintaining the core communication function of the integrated interlocking device by reflecting signs of power instability that are difficult to detect with only the surface battery remaining capacity.

[0168] A data processing unit (120) according to one embodiment of the present invention may be configured to perform a mechanical fatigue and lifespan prediction process that considers multiple deterioration factors together, rather than relying solely on the number of accumulated connections, in order to reflect the fact that mechanical fatigue and reduced contact reliability of the connector part (150) may accumulate due to repeated connection and disconnection, field vibration, temperature fluctuations, and long-term operation in an integrated interlocking device configured as a modular type. The above process 4 is intended to identify in advance the possibility of damage due to wear, reduced connection force, micro relative motion, and thermal expansion stress of the connector part (150), and to be utilized for determining maintenance timing and power protection control.

[0169] The data processing unit (120) can first obtain a first degradation factor that accumulates gradually. The first degradation factor may include the cumulative number of connections of the connector part (150), the historical difference between the insertion force and the separation force measured at each connection and separation, and the contact plating wear area ratio. The cumulative number of connections may be stored as an integer value by counting the contact signal, lock completion signal, or connection event log generated during connector connection. The historical difference between the insertion force and the separation force may be calculated as the difference between the maximum compressive load applied during connection and the maximum tensile load required during separation, and if the difference increases, it may be determined that the elastic restoring force of the contact is decreasing, the connection friction state is changing, or local deformation of the connection part is progressing. The contact plating wear area ratio may be calculated as the ratio of the worn or damaged area to the total plating area based on changes in contact resistance, changes in surface reflectance, results of contact surface image analysis, or a combination thereof.

[0170] The data processing unit (120) may subsequently obtain a second degradation factor capable of causing accelerated degradation. The second degradation factor may include accumulated micro-sliding displacement due to a vibration environment, thermal stress based on the difference in linear expansion coefficients between dissimilar materials and the temperature fluctuation range, and the residual coupling force of the latch. The accumulated micro-sliding displacement may be calculated as the total sum of repeated accumulation of relative movement in micrometer units occurring between the pin and the socket due to external vibration or shock while the connector is connected. The thermal stress may be calculated by combining the difference in linear expansion coefficients existing between the metal housing and the plastic connector, or between the connecting parts of different materials, and the temperature fluctuation range repeated during operation. The residual coupling force of the latch refers to the current holding force of the locking structure that maintains the connected state after the connector is connected, and may be measured as the ratio of the currently maintainable coupling force to the initial design standard or as an absolute load value.

[0171] The data processing unit (120) may perform a stepwise processing procedure that reflects mechanical fatigue accumulation characteristics, rather than simply summing the first degradation factor and the second degradation factor. First, the data processing unit (120) may form a basic fatigue score based on the cumulative number of fastenings, the historical difference between insertion force and separation force, and the contact plating wear area ratio. At this time, the first degradation factors may increase relatively sensitively in the initial fastening section, but after fastening and wear have progressed beyond a certain level, the rate of increase may be processed to gradually become gradual. Accordingly, the data processing unit (120) may be configured to add the first degradation factors to the total fatigue accumulation score gradually.

[0172] Subsequently, the data processing unit (120) can determine whether accelerated deterioration occurs based on accumulated micro-sliding displacement, thermal stress, and residual coupling force of the latch. If the accumulated micro-sliding displacement increases, the likelihood of fretting wear or micro-contact instability on the contact surface may increase, and if the thermal stress increases, the accumulation of deformation in the joint may occur due to repeated deformation between dissimilar materials. Additionally, if the residual coupling force of the latch decreases, the likelihood of connector detachment or contact failure may increase even under the same external force conditions. Accordingly, the data processing unit (120) may be configured to apply additional weight to the basic fatigue score if at least one of the second deterioration factors exceeds a preset allowable range or if multiple second deterioration factors deteriorate simultaneously.

[0173] The residual coupling force of the above latch is not limited to a simple final comparison criterion but can also be reflected in the fatigue calculation step. For example, as the residual coupling force of the above latch decreases below a reference level, it can be configured so that a larger level of additional weighting is applied for the same cumulative micro-slipping displacement or the same thermal stress. This is because, when the coupling retention capacity is low, the likelihood of contact instability or detachment occurring even with relatively small vibrations or shocks increases. Accordingly, the data processing unit (120) can utilize the residual coupling force of the above latch as both a weighting adjustment factor and a final determination factor for the second deterioration factor.

[0174] The data processing unit (120) can perform maintenance warning and protection operations based on the final fatigue score calculated as above. For example, if the final fatigue score exceeds the first maintenance standard, the data processing unit (120) can send an inspection recommendation message to the administrator terminal or the command and control system (30). If the final fatigue score exceeds the second maintenance standard, the data processing unit (120) can identify the connector part (150) or the corresponding additional interlocking module (200) that requires maintenance first and send a replacement recommendation message. In addition, if the final fatigue score exceeds the detachment risk standard set in correspondence with the residual coupling force of the latch, the data processing unit (120) can control the high voltage or high current power applied to the module connected to the connector part (150) by preemptively cutting off or limiting it to reduce secondary damage caused by short circuits, sparks, or module detachment.

[0175] The data processing unit (120) may also perform an exception handling procedure to remove temporary physical noise during the fatigue calculation process. For example, if a worker inserts a connector at an angle and then immediately separates it, the historical difference between the insertion force and the separation force may be measured as abnormally large. In this case, if the maintenance time of the corresponding connection event is less than the preset minimum connection maintenance time, the data processing unit (120) may not regard it as a connection event that occurred during normal operation, but rather determine it as a temporary disturbance during the connection attempt process and exclude it from the fatigue accumulation calculation. Additionally, if the accumulated micro-slipping displacement or residual connection force value measured at a single point in time does not match the changes in other factors, the data processing unit (120) may be configured to determine whether to finally reflect the re-measurement value or adjacent sensor value from multiple points in time after cross-verification. Accordingly, the situation in which the fatigue score rises excessively due to temporary measurement errors can be reduced.

[0176] As an embodiment of the present invention, a situation may be assumed in which a plurality of sensor modules are repeatedly attached to and detached from an integrated interlocking device deployed in a field unit. The data processing unit (120) may form a basic fatigue score based on the number of times the device is fastened over a certain period, the historical difference between the insertion force and the separation force, and the contact plating wear area ratio. Since the first deterioration factors are mainly reflected in this stage, the fatigue score may increase gradually. Subsequently, when the integrated interlocking device is mounted on a tracked vehicle or a high-vibration platform and travels for a long period, if the accumulated micro-sliding displacement between the connector pin and the socket increases, and at the same time the thermal stress exceeds the allowable range due to large temperature fluctuations between day and night, the data processing unit (120) may determine this as an accelerated deterioration state and apply an additional weight to the basic fatigue score. If it is confirmed that the residual coupling force of the latch has also significantly decreased compared to the initial standard during the above process, the data processing unit (120) may apply a higher level of weight to the same deterioration state to adjust the final fatigue score upward. As a result, if the above final fatigue score exceeds the priority maintenance standard or the detachment risk standard, the data processing unit (120) can send a replacement recommendation message to the manager for the corresponding connector part (150) and, if necessary, control the power of the corresponding module to be limited.

[0177] As another embodiment, it may be assumed that even if the cumulative number of fastenings itself is not large, repetitive shocks and large temperature fluctuations are concentrated during a specific operating period. In this case, the basic fatigue score based on the first degradation factor may not be high; however, if the cumulative micro-sliding displacement and the thermal stress increase simultaneously and the residual coupling force of the latch also decreases, the data processing unit (120) may determine that the risk of actual lifespan degradation has increased rapidly and significantly increase the final fatigue score. Accordingly, the impact of a harsh operating environment, which is difficult to capture when based solely on the number of fastenings, can be reflected at an earlier stage.

[0178] Each reference value, allowable range, and weight used in the above process 4 is not limited to fixed values. These values ​​may be set or updated based on the history of contact failures accumulated during operation and the repetitive fastening test, vibration test, temperature cycling test, and contact wear test performed during the initial setup of the device. For example, the reference value for the historical difference between the insertion force and the separation force may be set based on the result of comparing the fastening force distribution in the initial design state with the fastening force distribution after long-term use, and the allowable range for the accumulated micro-slipping displacement may be set by referring to the section where contact failures begin to increase significantly during the repetitive vibration test. Additionally, the reference value for the residual coupling force of the latch may be set by reflecting the module's self-weight, maximum acceleration impact, and the dynamic load conditions of the operating platform.

[0179] As such, Process 4 of the present invention evaluates the cumulative number of fastenings, changes in fastening force, contact wear, cumulative micro-sliding displacement, thermal stress, and residual coupling force of the latch in stages, and calculates a final fatigue score by distinguishing between gradual cumulative deterioration and accelerated deterioration, thereby allowing for a more detailed reflection of the actual operational severity and the state of deterioration of the coupling structure, which are difficult to reflect in a replacement judgment method based on the number of simple uses. Accordingly, the integrated interlocking device can identify signs of lifespan degradation of the connector part (150) at an earlier stage even under conditions where field vibration, repeated attachment and detachment, rapid temperature changes, and long-term operation overlap, and can be utilized for establishing maintenance plans and device protection control.

[0180] According to one embodiment of the present invention, the final fatigue score used in process 4 can be calculated by stepwise reflecting a basic cumulative score formed by the cumulative number of fastenings, the hysteresis difference between insertion force and separation force, and the contact plating wear area ratio, and an accelerated degradation weighting factor assigned by cumulative micro-sliding displacement and thermal stress. In addition, even if the residual bonding force of the latch compared with the final fatigue score is measured as a direct force value, it can be converted into a standardized residual bonding force index for comparison judgment and compared on the same scale as the fatigue score. The reference value and weighting interval can be set based on a reference profile that combines the history of repeated fastening tests, vibration tests, thermal shock tests, and contact failures.

[0181] In an exemplary simulation to verify the appropriate range of the above fatigue threshold, the first simulation assumes a state where the base cumulative score is at the level of 10 points and the accelerated degradation factor is almost non-existent. In this case, the final fatigue score can be maintained at the level of 10 points, and the standardized residual latch coupling strength index is evaluated at the level of 95 points, serving as an example of a very stable coupling state. In the second simulation, it assumes a case where the base cumulative score is at the level of 30 points and the accelerated degradation factor appears mildly. In this case, the final fatigue score may increase to the level of 35 points, but the standardized residual coupling strength index is maintained at the level of 88 points, so it can still be evaluated as a stable coupling state. In the third simulation, it assumes a state where the base cumulative score is at the level of 50 points and the accelerated degradation factor occurs intermittently. In this case, the final fatigue score may rise to the level of approximately 60 points, and the standardized residual coupling strength index is maintained at the level of 80 points, serving as an example where aging proceeds but remains within the normal operating range.

[0182] In the fourth simulation, a state in which a basic cumulative score of 65 points is combined with a continuous accelerated degradation factor can be assumed. In this case, the final fatigue score may rise to approximately 82 points, and the standardized residual coupling strength index may drop to 75 points, serving as an example of a warning zone where early signs of micro-sparks or coupling instability may be observed. In the fifth simulation, a case in which a basic cumulative score of 70 points is superimposed with an extreme accelerated degradation factor can be assumed. In this case, the final fatigue score may be evaluated to approximately 98 points, and the standardized residual coupling strength index may drop to 65 points, serving as an example of a replacement recommendation zone where the likelihood of communication packet loss during vibration increases.

[0183] The impact of harsh environments can be reviewed separately even in cases of low usage frequency. In the 6th simulation, a state can be assumed where the base cumulative score is not high at the level of 20 points, but vibration and thermal stress act very significantly. In this case, the final fatigue score can rise sharply to the level of approximately 85 points, and the standardized residual bonding strength index is evaluated at the level of 70 points, serving as an example demonstrating that even with low usage frequency, a harsh environment alone can approach a state of imminent failure. In the 7th simulation, a state can be assumed where the base cumulative score is high at the level of 80 points and the accelerated degradation factor is minor, but the standardized residual bonding strength index drops to the level of 82 points. In this case, the final fatigue score and the residual bonding strength index can be evaluated as being in a borderline state where they are close to each other, and the connector part can be classified as a priority inspection target. In the 8th simulation, a case can be assumed where an extreme accelerated degradation factor is added to the base cumulative score of 40 points, causing the final fatigue score to reach the level of 95 points and the standardized residual bonding strength index to drop to the level of 60 points. In this case, it can serve as an example representing a condition where reduced latch tension and connector shaking can lead to a substantial risk of detachment. In the 9th simulation, it can be assumed that a combination of a base cumulative score of 90 points and a continuous accelerated degradation factor causes the final fatigue score to rise to 120 points, while the standardized residual coupling strength index decreases to 50 points. In this case, it can be interpreted as a state where there is a very high probability that the connector will detach due to external vibration or self-weight. In the 10th simulation, it can be assumed that even with a base cumulative score of 30 points, a very severe accelerated degradation environment acts to cause the final fatigue score to rise to 105 points, while the standardized residual coupling strength index decreases to 55 points. In this case, it can be used as an example of a state where internal pin wear and contact failures accumulate, significantly increasing data communication instability.

[0184] The effectiveness of the fatigue threshold and residual bonding strength comparison rules set as described above can be verified through comparative simulations. For example, in an environment where vibration and thermal stress are severe, even though the number of fastening cycles is not high (approximately 20 cycles), a management method based on the number of fastening cycles may not be able to take special measures on the grounds that the guaranteed number of cycles has not been reached. On the other hand, the method of the present invention can generate a replacement warning at an earlier stage by reflecting accumulated micro-slipping displacement and thermal stress as accelerated deterioration factors. Furthermore, even if the number of fastening cycles is at the level of 80 cycles, if vibration and thermal stress are good and the residual bonding strength of the latch maintains a reference range, a management method based on the number of cycles may order a batch replacement; however, the method of the present invention can determine that the risk criterion has not yet been reached by comparing the final fatigue score with the standardized residual bonding strength index. Furthermore, when the number of fastening cycles, vibration, and thermal stress all increase and the residual coupling force of the latch is significantly reduced, a simple fastening cycle-based management method may not adequately reflect the risk of connector detachment, short circuit, or fire during operation in advance, whereas the method of the present invention can detect the section where the residual coupling force is reversed and proactively perform power cutoff and maintenance warnings. Accordingly, the above process 4 can be utilized to reflect the actual operational severity and structural deterioration state more precisely than a simple cycle-based maintenance method.

[0185] An integrated interlocking device according to one embodiment of the present invention may be configured to be positioned between one or more surveillance and reconnaissance sensor systems (10) and one or more communication networks (20), and to transmit surveillance and reconnaissance data acquired from the surveillance and reconnaissance sensor systems (10) to a command and control / weapon system (30). The integrated interlocking device may include a housing (110), a data processing unit (120), an interlocking unit (130), a communication unit (140), a connector part (150), and, if necessary, an additional interlocking module (200). The interlocking unit (130) may include an Ethernet interlocking unit (131) and a serial interlocking unit (132), and the data processing unit (120) may be configured to comprehensively control the operating status of the interlocking unit (130), the communication unit (140), and the additional interlocking module (200).

[0186] The above surveillance and reconnaissance sensor system (10) may include a radar, an electro-optical camera, an infrared camera, a radio wave receiving device, a seismic vibration sensor, or an external surveillance and reconnaissance device similar thereto. The above surveillance and reconnaissance sensor system (10) may be connected to the integrated linkage device through the Ethernet linkage unit (131) or the serial linkage unit (132). For example, the radar may be connected to the Ethernet linkage unit (131) to transmit an Ethernet-based detection message, and the seismic vibration sensor may be connected to provide vibration response data in the form of a serial signal to the serial linkage unit (132). Additionally, the electro-optical camera or the infrared camera may be configured to transmit image frames, metadata, or target area feature values ​​to the linkage unit (130).

[0187] When the system starts, the data processing unit (120) can first check the configuration status of the currently installed linkage unit (130), communication unit (140), and additional linkage module (200). The data processing unit (120) can recognize the number of modules connected through the connector part (150), module types, port placement status, activation status, and communication capability status of each module, and can set an initial operation profile based on this. At this time, the data processing unit (120) can load a stored configuration file to refer to which sensor system is connected to which linkage unit (130), which communication network (20) is used as the priority transmission path, and what range the reference value of each process is set to.

[0188] The data processing unit (120) may be configured to continuously collect data received from the surveillance and reconnaissance sensor system (10) after system startup, but not to immediately transmit the collected data to the outside, and to evaluate the data and the device status together by applying processes 1 to 4 sequentially or in parallel. Specifically, the data processing unit (120) may perform process 1 that reflects the physical status of the housing (110) and the additional linkage module (200), perform process 2 that determines the reliability of target data obtained from the surveillance and reconnaissance sensor system (10), perform process 3 that determines the transmission output and transmission path of the communication unit (140), and perform process 4 that determines the fatigue and lifespan status of the connector part (150). Each of the processes may be configured not to operate independently of each other, but to coordinate the operation of the entire device by referencing the results of each other.

[0189] First, the data processing unit (120) can determine the internal state of the housing (110) of the integrated interlocking device through Process 1. In Process 1, the data processing unit (120) can collect the number of additional interlocking modules (200) connected to the connector part (150), the shielding opening ratio, the heat accumulation state, the ground path impedance discontinuity, the fine air gap ratio, and the electromagnetic energy residual time of the cavity inside the housing (110). Based on these values, the data processing unit (120) can calculate the thermal-electromagnetic stress index inside the housing (110) and determine whether the stress index exceeds a preset step-by-step reference value. If the stress index remains in a relatively low range, the data processing unit (120) can maintain sensor collection and communication control in a normal mode. On the other hand, if the stress index exceeds a first reference value, the load can be reduced by limiting the data processing volume for the additional linkage module (200) or the specific linkage unit (130); if it exceeds a second reference value, the cooling fan or heat dissipation auxiliary circuit can be actively operated; and if it exceeds a third reference value, the power supply to the module with a lower priority can be limited or temporarily suspended.

[0190] The result of the above process 1 may also affect the input conditions of subsequent processes 2 and 3. For example, if the internal stress of the housing (110) increases and the data throughput of a specific additional linkage module (200) is limited, the data processing unit (120) may reduce the update cycle of sensor data received from the limited module or degrade the sensor data to auxiliary information and reflect this in the subsequent detection reliability judgment. Additionally, if the stress index enters a higher stage, the data processing unit (120) may conservatively adjust the transmission output in process 3 or set it to prioritize a path with relatively low load instead of a communication path requiring high-output transmission. Accordingly, the above process 1 can operate as a higher condition for overall sensor fusion and transmission control, going beyond a simple protection function.

[0191] Subsequently, the data processing unit (120) can perform process 2 to determine the detection reliability of target information received from the surveillance and reconnaissance sensor system (10). The data processing unit (120) can refer together with the target distance, velocity, and Doppler change information obtained from the radar, and the thermal image, background contrast information, and target contour information obtained from the electro-optical camera or infrared camera. In addition, if the seismic motion sensor is present, the vibration response pattern over time can be referred together to calculate the degree of motion agreement between the radar motion information and the vibration response. After forming an initial reliability based on the thermal contrast and the degree of motion agreement, the data processing unit (120) can correct the initial reliability by reflecting the condensation margin deficit, scattering attenuation coefficient, polarization mismatch loss, and sensor axis alignment error.

[0192] The data processing unit (120) can classify the results of the process 2 into multiple reliability grades. For example, if the final reliability corresponds to a high-reliability section, the target information can be classified as high-priority data. If the intermediate section corresponds to a middle section, the target information can be classified as a reconfirmation target or an auxiliary tracking target. If the low section corresponds to a low-reliability section, the transmission of immediate strike specifications can be withheld, and the target can be displayed as a low-priority target on the operator screen, or the target can be switched to a logical waiting state until subsequent sensor data for the same target is obtained continuously for a certain number of times or more. In this way, the process 2 can be used as a criterion for determining the transmission priority and data format in the process 3.

[0193] For example, if the radar and the electro-optical camera detect the same target, the thermal contrast of the target is high, and the Doppler change pattern of the radar matches the response pattern of the seismic motion sensor to a high degree, the data processing unit (120) can form a high initial reliability. However, if the lens surface temperature approaches the dew point, the condensation margin deficit increases, the scattering attenuation coefficient rises due to fog or sea fog, and the sensor axis alignment error approaches the allowable range, the data processing unit (120) can lower the initial reliability and finally classify it as an intermediate grade or a grade requiring re-verification. In this case, the target information may be processed as auxiliary data for additional verification instead of being used as immediate firing data.

[0194] The final reliability and grade information calculated in the above process 2 can be immediately transmitted to process 3. The data processing unit (120) can determine the transmission priority by evaluating the effective power status and propagation path attenuation status in process 3, while simultaneously referring to the grade of the target information determined in the above process 2. The data processing unit (120) can calculate the effective power status based on the remaining battery energy, survival threshold energy, battery internal resistance, and the voltage drop rate at the moment of transmission initiation. If the effective power status is sufficient, the normal transmission mode may be maintained, but if the effective power status approaches or falls below the limit range, high-power transmission may be restricted and switched to survival communication mode. In the survival communication mode, the transmission of large-capacity video data or continuous raw sensor streams may be reduced, and transmission may be configured to focus on key information such as location coordinates, status codes, and short alarm messages.

[0195] The data processing unit (120) can adjust the transmission output level by evaluating the first Fresnel zone shielding rate, polarization mismatch loss, yaw direction fine fluctuation dispersion, and the wavelength of the communication network (20) currently in use while in a state where normal transmission is possible. If the first Fresnel zone shielding rate increases or the polarization mismatch loss increases, the data processing unit (120) can determine that the transmission efficiency of the propagation path has decreased and can lower the transmission output within a certain range. In addition, if the yaw direction fine fluctuation of the platform increases, the influence of directional error may appear more significantly in a communication network with a shorter wavelength even with the same fluctuation; therefore, the data processing unit (120) can adjust the output adjustment range by referring to the wavelength length together. As a result of this determination, if the efficiency of the wireless communication network currently in use is low and an alternative low-power path exists, the data processing unit (120) can perform a bypass switch to a mobile communication network, a wired communication network, or a communication path in another frequency band.

[0196] The above process 3 can be directly linked to the above process 2. For example, target data classified as high reliability in the above process 2 can be classified as priority transmission target data in the above process 3 and can be transmitted preferentially to the command and control system (30) through a relatively stable communication network. On the other hand, target data classified as medium grade can be transmitted through a low-power auxiliary transmission channel or can be transmitted after being stored in a buffer for a certain period of time. Target data classified as low grade or re-verification target grade can be immediately excluded from transmission targets in the above survival communication mode and can be included as a subsequent transmission target only after the effective power state is restored or the re-verification procedure is completed. Accordingly, the above data processing unit (120) can allocate communication resources by reflecting both power conditions and the importance of target information.

[0197] Meanwhile, the data processing unit (120) may perform process 4 in parallel to track the structural deterioration of the connector part (150) over the long term. The data processing unit (120) may collect the cumulative number of fastenings, the historical difference between insertion force and separation force, and the contact plating wear area ratio as first deterioration factors, and collect cumulative micro-sliding displacement, thermal stress based on the difference in thermal expansion coefficients between dissimilar materials, and the residual coupling force of the latch as second deterioration factors. The data processing unit (120) may form a basic fatigue score by applying a gradual accumulation method to the first deterioration factor, and may apply additional weights to the basic fatigue score by determining whether the allowable range is exceeded or whether multiple factors deteriorate simultaneously for the second deterioration factor. At this time, the residual coupling force of the latch is not used merely as a simple comparison criterion, but may be utilized as an adjustment factor so that a higher level of weight is applied to the same vibration or thermal stress as the coupling retention capacity is lower.

[0198] The result of the above process 4 can also be directly linked to the above process 1. For example, if the fatigue score of the connector part (150) increases and the residual coupling force of the latch decreases, the data processing unit (120) may determine that the micro-air gap ratio of the junction and the discontinuity of the ground path impedance are likely to increase more easily in the future. In this case, the data processing unit (120) may increase the sensitivity to the electromagnetic leakage factor in process 1 or apply a conservative stress judgment criterion to a specific additional interlocking module (200). Conversely, if micro-air gaps or impedance abnormalities are repeatedly detected in process 1, the data processing unit (120) may reflect the phenomenon in the fatigue calculation of process 4 to further increase the degradation score of the connector part (150). Accordingly, process 1 and process 4 may have a structure that interprets the internal state of the hardware in a mutually complementary manner.

[0199] The results of the above process 4 may also affect processes 2 and 3. For example, if the fatigue score for a specific channel of the connector part (150) is high and the residual coupling force is reduced, the data processing unit (120) may add a re-verification weight in process 2 to the data of the surveillance and reconnaissance sensor system (10) connected to the channel, or utilize the sensor data by downgrading it from primary data to auxiliary data. Additionally, if the fatigue score exceeds the priority maintenance standard, the data processing unit (120) may restrict high-capacity transmission or high-output transmission through the channel in process 3, and, if necessary, reduce or cut off the power supply to the channel.

[0200] An integrated embodiment applying such an interconnected structure to a specific operational situation is described as follows. For example, it can be assumed that the integrated interconnection device is installed in a vehicle or a coastal surveillance base, and that a radar, an electro-optical camera, an infrared camera, and a seismic vibration sensor are connected to the interconnection unit (130), and that an auxiliary communication channel for satellite communication is expanded through an additional interconnection module (200). In the initial stage of operation, the data processing unit (120) checks the system configuration status and can confirm through Process 1 that it is in a normal range with low internal stress of the housing (110). In this state, if the radar and the electro-optical camera detect the same small target and the thermal contrast of the infrared camera and the motion matching of the seismic vibration sensor appear good, the data processing unit (120) can classify the target into a high reliability grade through Process 2. Afterward, in the above process 3, it is determined that the effective power state is sufficient and the propagation environment is good, so the target information can be transmitted to the command and control system (30) via a wired communication network or a priority communication network as high-priority data.

[0201] It can be assumed that as operating time elapses, the number of additional linkage modules (200) increases, the duration of the internal temperature rise of the housing (110) and the heat return delay time become longer, and the ratio of fine air gaps in the connector joint increases due to vibration. In this case, the data processing unit (120) determines through process 1 that the thermal-electromagnetic stress index has increased and may limit the data processing volume of some of the additional linkage modules (200) or strengthen the heat dissipation operation. At the same time, in process 4, it may be confirmed that the fatigue score reflecting the cumulative number of connections, the insertion force-separation force history difference, and the cumulative fine slip displacement of the connector part (150) increases, and the residual coupling force of a specific latch has decreased. The data processing unit (120) may control the re-verification weight when evaluating the reliability of sensor data connected to the corresponding connector path by reflecting the above results, or exclude it from the high-load transmission path.

[0202] Additionally, it can be assumed that at the same time, the external environment deteriorates, causing sea fog to thicken, the lens condensation margin to increase, and the sensor axis alignment error approaches the allowable range. The data processing unit (120) can lower the target data, which initially had high reliability, to an intermediate grade or a grade requiring re-verification through process 2. In this case, even if the effective power state is within the normal range, process 3 may change the priority to light transmission in the form of auxiliary data or subsequent re-verification request messages, rather than maintaining high-power image transmission, on the grounds that the grade of the data has been lowered. Furthermore, if the effective power state also deteriorates simultaneously, the data processing unit (120) may stop the transmission of large-capacity data for the target and control the transmission to only coordinate information and a brief status code in a survival communication mode.

[0203] As described above, in the integrated embodiment of the present invention, each process does not exist as an individual monitoring function, but rather has a structure in which the same data processing unit (120) controls in stages while reflecting the hardware structure status, sensor detection reliability, communication availability status, and connector lifespan status together. Process 1 monitors the physical stress of the housing (110) and the additional interlocking module (200) to determine higher operating conditions, Process 2 determines the reliability and grade of the sensor fusion data, Process 3 selects the transmission mode, output, and communication network path by reflecting the grade and power status, and Process 4 tracks the long-term deterioration of the connector part (150) to provide hardware maintenance and protection standards. Accordingly, the integrated interlocking device can perform sensor data processing, hardware protection, and transmission control as a single continuous management system even in an operating environment where a plurality of surveillance and reconnaissance sensor systems (10), a plurality of communication networks (20), and module expansion structures exist together.

Various modifications are possible by those skilled in the art without departing from the essence of the invention as claimed in the claims, and such modifications should not be understood individually from the technical spirit or perspective of the present invention.
