Description

Technical Field

[0001] This invention relates to the field of power and environmental monitoring and control technology for communication cabinets, and more specifically, to a modular and scalable intelligent converged terminal. Background Technology

[0002] As communication networks extend to edge sites, roadsides, industrial park nodes, and remote areas, more and more communication equipment is being deployed in the form of outdoor communication cabinets. Outdoor communication cabinets are typically located in unattended environments. In addition to the main communication equipment, the cabinets also house power supplies such as switching power supplies, battery banks, fans or air conditioners, as well as environmental monitoring instruments such as temperature and humidity sensors, water level sensors, and door magnetic detection components. To ensure the long-term stable operation of the equipment within the cabinets, it is usually necessary to centrally access, comprehensively assess, and implement coordinated control measures for the operating status of the power equipment, environmental conditions, and abnormal events.

[0003] In existing technologies, environmental monitoring terminals mostly adopt fixed hardware structures, with the number of interfaces, communication methods, and data acquisition capabilities fixed at the factory. Existing patent CN204576168U proposes an IoT-based power environment monitoring device, focusing on wireless communication and environmental monitoring between the power environment remote monitoring terminal and the power environment monitor. In 2012, Zheng Xiaobo published "Research on Centralized Monitoring System for Power and Environment in Computer Rooms" in the journal *Railway Computer Applications*, focusing on centralized monitoring of power equipment, air conditioning equipment, and environmental information in computer rooms. In 2021, Zhang Yanjun published "Application of BIM Technology in Intelligent Integrated Cabinets" in the same journal, discussing the integrated design of cabinets, power distribution, and air conditioning systems, highlighting the issue of collaborative configuration of multiple systems within the integrated cabinet. While these solutions have some practical value in their respective scenarios, none address the practical problems of significant differences in outdoor communication cabinet site configurations, frequent changes in interface requirements, and numerous future expansion and upgrades, providing a terminal overall architecture with scalable functional modules for flexible combination and configuration.

[0004] On the other hand, there are significant differences in equipment configuration between different outdoor communication cabinet sites. Some sites only need to connect to a switching power supply, battery monitoring module, and temperature and humidity detection components, while others also need to connect to an electricity meter, water level detection components, access control status detection components, and fan or air conditioning controllers. Some sites also require wireless access capabilities due to the installation of auxiliary side cabinets or remote wireless detection points. If fixed-model terminals are still developed and stocked separately for each site, it will not only lead to redundant R&D, complex models, and increased inventory pressure, but also often require the replacement of all terminals when the site is upgraded or expanded, resulting in high maintenance costs.

[0005] Furthermore, the operation and management of outdoor communication cabinets includes not only data acquisition and status uploading, but also equipment linkage control based on multi-source status information. The terminal needs to comprehensively assess the operating status of the cabinet's temperature, humidity, water level, access control, power supply, battery, and temperature control equipment, and take corresponding linkage measures under conditions such as high temperature, high water level, or abnormal door opening. In existing technologies, some solutions focus on single data monitoring or single communication reporting, lacking a modular dedicated terminal overall architecture for outdoor communication cabinet scenarios that accommodates multi-source access, functional module expansion, and linkage control.

[0006] Therefore, there is a need for a solution that can address the problem of existing terminals being difficult to configure flexibly according to site differences, while also reducing the costs of production, inventory, and subsequent upgrades. Summary of the Invention

[0007] To overcome the aforementioned deficiencies of existing technologies, this invention provides a modular and scalable intelligent converged terminal. It centralizes common capabilities such as basic power supply, main control processing, and inter-module communication management onto the terminal's main hardware. Variable field functions such as multi-channel RS-485 access, Ethernet access, switch quantity acquisition, and RF wireless access are configured as selectable extended function modules. The terminal's main hardware identifies the types of these extended function modules and establishes a function configuration table. This allows the terminal to automatically form interface resource mapping relationships and linkage control resource configuration relationships matching the current site under different combinations of function modules. This enhances the terminal's configurability during deployment and reduces the cost of subsequent expansion and upgrades. When site configuration changes, only the corresponding extended function modules need to be added, removed, or replaced, without replacing the entire terminal. This enables flexible combination deployment for different outdoor communication cabinet site configurations, thus solving the problems mentioned in the background technology.

[0008] To achieve the above objectives, the present invention provides the following technical solution: A modular and scalable intelligent converged terminal includes a housing, an external terminal block assembly, and further includes: The terminal hardware serves as the basic control platform for intelligent converged terminals.

[0009] The extended function module provides corresponding extended functions according to the equipment access requirements of different outdoor communication cabinet sites.

[0010] As a further aspect of the present invention, the terminal body hardware is used as the basic control platform for the intelligent fusion terminal. The terminal body hardware is located at the center of the housing and includes a power management circuit, a backup power circuit, a power sampling circuit, a main control processing circuit, an inter-module communication management circuit, an expansion module identification circuit, and a memory.

[0011] The power management circuit is used to manage the power supply, detect the status of the main power supply and the backup power supply, and be ready to switch at any time.

[0012] The backup power circuit is designed to promptly fill the gap when the main power supply fails, ensuring the normal operation of the terminal.

[0013] The power sampling circuit is used to receive external input power and to distribute power to the terminal hardware itself and its various extended functional modules. The power sampling circuit may include input protection, voltage conversion, and branch power supply control sections to ensure that the terminal hardware and extended functional modules can maintain stable operation even when there are voltage fluctuations or changes in the number of connected devices in the outdoor communication cabinet.

[0014] The main control processing circuit, as the main control unit of the terminal, is used to perform functions such as expansion module identification, function configuration generation, interface resource mapping, multi-source status data processing, and linkage control strategy execution. The main control processing circuit can adopt a structure combining a processor and a memory, wherein the memory is used to store the function configuration table, linkage rule table, status record information, and abnormal event log.

[0015] The inter-module communication management circuit is used to maintain data interaction between the terminal hardware and the extended functional modules. This circuit can adopt a unified internal bus structure. After different modules are selected and configured to a unified extended interface, the terminal hardware uniformly schedules the data transmission order and data sending / receiving process between modules, avoiding resource conflicts caused by the independent operation of each extended functional module.

[0016] The expansion module identification circuit is used to identify the type of each expansion function module during the terminal power-on initialization phase. The expansion module identification circuit can determine whether the currently selected configuration is an RS-485 module, an Ethernet module, or a wireless communication module by reading the pin status corresponding to the type of each unified expansion interface, or by reading the identification code output by the expansion module identification circuit in the expansion function module.

[0017] The terminal hardware is pre-configured with multiple unified expansion interfaces. Each unified expansion interface includes a power pin, a type identification pin, and a data bus pin. The power pin is used to provide operating power to the expansion function module located at the corresponding expansion position. The type identification pin is used to transmit the type information of the expansion function module to the terminal hardware. The data bus pin is used to realize data communication between the terminal hardware and the expansion function module.

[0018] After the terminal is powered on, the main control processing circuit, with the cooperation of the expansion module identification circuit, polls each unified expansion interface in turn, reads the type identification information of each expansion position one by one, and determines the type of expansion function module currently selected and configured in each expansion position according to the read type identification information, so as to form the current expansion module identification result of the terminal.

[0019] After obtaining the identification result of the expansion module, the main control processing circuit generates a function configuration table that matches the current function module combination state based on the expansion function module type corresponding to each expansion location. The function configuration table includes at least the module location number, module type, number of available interfaces, number of connected external terminals, and resource category undertaken by each interface channel during the linkage control process. The resource category includes at least status input resources, control output resources, and alarm reporting resources.

[0020] After generating the function configuration table, the main control processing circuit further establishes an interface resource mapping relationship between the specific terminals on the external terminal assembly and the actual functional channels of each extended function module based on the module location, module type, number of available interfaces and external terminal number recorded in the function configuration table.

[0021] After establishing the interface resource mapping relationship, the main control processing circuit reads the resource categories of each interface channel loaded in the function configuration table. Based on the resource categories of each interface channel, the main control processing circuit classifies and identifies each interface channel in the function configuration table, and associates each classified interface channel with the corresponding external wiring terminals and actual functional channels in the interface resource mapping relationship. This determines the type of linkage task that each interface channel can undertake under the current site configuration and generates a linkage control resource configuration relationship that matches the current site configuration.

[0022] After the terminal hardware forms the interface resource mapping relationship and the linkage control resource configuration relationship, it enables the intelligent converged terminal to form an access structure and linkage control structure that matches the current site under the current functional module combination conditions, thereby realizing adaptive deployment for different site configurations.

[0023] When the site configuration changes, only the extended functional modules in the corresponding extended locations need to be added, removed, or replaced. The terminal hardware can then re-execute the processes of functional module type identification, functional configuration generation, interface resource mapping establishment, and linkage control resource configuration establishment, thereby forming a terminal structure that matches the new site configuration. Since the terminal hardware in the main body remains unchanged, terminal function reconstruction and site re-adaptation can be completed without replacing the entire terminal body when the site configuration changes.

[0024] As a further aspect of this invention, the extended function modules provide corresponding extended functions according to the equipment access requirements of different outdoor communication cabinet sites, including the following specific contents: the extended function modules include at least one of the following: an RS-485 module, an Ethernet module, a switch quantity acquisition module, and a wireless communication module. Each extended function module is connected to the terminal hardware through a unified extended interface, thereby establishing a power supply connection and a data communication connection. Through the above design, the variable functions required by the site are no longer fixed on the terminal hardware, but are modularly carried by different extended function modules, enabling the same terminal hardware platform to combine different extended capabilities as needed.

[0025] Furthermore, each extended function module can be equipped with an extended module identification circuit and an interface adaptation circuit. The extended module identification circuit is used to output function module type information to the terminal hardware, so that the terminal hardware can identify the type and quantity of currently connected extended function modules during the power-on initialization phase. The interface adaptation circuit is used to convert the external device interface level, acquisition signal, or wireless signal into a data format that can be uniformly processed by the terminal hardware, according to the specific function of the extended function module. Thus, the terminal hardware can automatically establish the current terminal's function configuration table and interface resource mapping relationship by reading the function module type information without changing the overall hardware architecture.

[0026] The RS-485 module is used to connect to serial port devices such as switching power supply modules, battery monitoring modules, electricity meters, fan controllers, air conditioner controllers, temperature sensors, water level sensors, or other environmental monitoring instruments that output continuously changing electrical signals. Through the RS-485 module, the terminal can be adapted to a large number of serial monitored and controlled devices in outdoor communication cabinets, and the number of RS-485 interfaces can be flexibly increased or decreased according to the specific site configuration.

[0027] The Ethernet module is used to connect the intelligent converged terminal to a remote monitoring platform, site management host, or operation and maintenance server, so that the device status information, environmental status information, abnormal alarm information, and linkage execution results processed by the terminal hardware can be uploaded through a wired network; at the same time, the Ethernet module can also be used to receive configuration management instructions issued by the remote operation and maintenance platform.

[0028] The switch quantity acquisition module is used to collect switch quantity data such as equipment operating status, equipment alarm status, and access control detection status. Through the switch quantity acquisition module, the terminal hardware can acquire alarm information or status parameters from the outdoor communication cabinet and use them in a comprehensive judgment together with the power equipment status information.

[0029] The wireless communication module is used to access wireless detection nodes in the cabinet auxiliary area, side cabinet area, or other locations where wiring is inconvenient. Through the wireless communication module, this invention can integrate remote auxiliary monitoring points into a unified monitoring and linkage control system without extending the distance of wired cabling.

[0030] As a further aspect of the present invention, the present invention does not lie in a single communication interface or a single sensing method, but rather in the hierarchical design of the terminal hardware and extended functional modules, enabling the terminal to form a unified basic platform and on-demand expansion capability in outdoor communication cabinet scenarios.

[0031] Specifically, the terminal hardware is responsible for all stable and unchanging general capabilities, including basic power supply, main control processing, inter-module communication management, and linkage control decisions. The frequently changing access requirements at different sites, such as the number of serial port devices, whether Ethernet upload is required, whether switch signal acquisition is required, and whether wireless auxiliary access is required, are handled by the corresponding extended function modules. Thus, when deployed at different outdoor communication cabinet sites, only adding, removing, or replacing different extended function modules on the same terminal hardware platform is needed to create a dedicated terminal configuration adapted to the current site.

[0032] After the terminal is powered on, the terminal hardware first polls each expansion selection configuration location sequentially through the unified expansion interface, reads the function module type information of each expansion function module, and generates a function configuration table corresponding to the actual combination of function modules in the current terminal. This function configuration table includes at least the expansion function types, number of interfaces, function module locations, and corresponding external terminal block resources of the current terminal. Subsequently, the terminal hardware establishes an interface resource mapping relationship based on the function configuration table, so that a clear correspondence is formed between the external terminal block components and the selected configuration expansion function modules.

[0033] During operation, the terminal hardware continuously receives power equipment status information and environmental status information uploaded by various extended function modules, forming a multi-source status set for the outdoor communication cabinet. This multi-source status information includes at least one or more of the following: power supply operating status, battery monitoring status, fan operating status, air conditioning operating status, access control status, temperature status, humidity status, and water level status. The terminal hardware comprehensively judges the above multi-source status information according to a preset linkage rule table and outputs linkage control commands or abnormal alarm information.

[0034] For example, when the terminal hardware determines that the temperature inside the cabinet exceeds a set threshold, it can first output a start or speed adjustment command to the fan controller through the corresponding interface; if the temperature continues to rise and the fan does not recover after being put into operation, it can further output an operation command to the air conditioning controller; when an abnormal water level is detected, an abnormal alarm message can be output immediately and protective control can be executed; when a change in access control status and an environmental abnormality occur simultaneously, an abnormal event log can be recorded and reported to the remote monitoring platform. Therefore, this invention is not simply a data acquisition terminal or a signal transmission terminal, but a modular, scalable, and configurable intelligent control terminal in an outdoor communication cabinet environmental control system.

[0035] The technical effects and advantages of this modular and scalable intelligent converged terminal are as follows: This invention centralizes stable and unchanging general capabilities such as basic power supply, main control processing, inter-module communication management, and linkage control decision-making onto the terminal hardware itself. It also sets up selectable extended function modules for functions that vary depending on the site, such as RS-485 access, Ethernet access, switch quantity acquisition, and RF wireless access. This allows the same terminal platform to be flexibly combined and configured according to the equipment access requirements of different outdoor communication cabinet sites. Simultaneously, after power-on, the terminal hardware automatically identifies the types of extended function modules, generates a function configuration table matching the current function module combination state, and further establishes interface resource mapping relationships and linkage control resource configuration relationships. This ensures a clear correspondence between external terminals, module function channels, and external devices, and enables orderly linkage of status input, control output, and alarm reporting under the current site conditions. During operation, the terminal can also comprehensively judge the status information from multiple sources such as switching power supply, battery, fan, air conditioner, access control, temperature and humidity, and water level, and output corresponding control commands and alarm information. This invention not only improves the adaptability and scalability of deployment at different sites, but also avoids the problems of repetitive R&D, complex models, high inventory pressure and high later upgrade and maintenance costs caused by developing, stocking and replacing fixed model terminals at each site. It achieves a modular, scalable and interconnected intelligent control effect for outdoor communication cabinet scenarios. Attached Figure Description

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Example 1 This embodiment provides a modular and scalable intelligent fusion terminal for outdoor communication cabinet power environment monitoring and equipment linkage control scenarios, such as... Figure 1 As shown, the intelligent converged terminal includes a housing 1, which contains terminal body hardware. The terminal body hardware serves as the basic control platform for the intelligent converged terminal and also includes several function expansion slots 200. The function expansion slots 200 can be connected to corresponding extended function modules according to the equipment access requirements of different outdoor communication cabinet sites.

[0044] In this embodiment, the housing 1 adopts a standardized installation structure suitable for installation in an outdoor communication cabinet. The housing 1 internally provides a terminal hardware mounting position and multiple expansion module mounting positions. The terminal hardware mounting positions and expansion module mounting positions are connected via a unified expansion interface 2. An external terminal block assembly is located on the wiring side of the housing 1 for connecting to external devices in the outdoor communication cabinet. The external terminal block assembly can be divided into a serial port wiring area, an analog signal wiring area, a network wiring area, and a power supply wiring area according to the site's usage requirements, and each area corresponds to a specific expansion module. For example... Figure 2 The image shown is a line drawing of the actual intelligent fusion terminal.

[0045] Different outdoor communication cabinet sites can be configured with one or more modules of the same type, or a mixture of different types of modules, depending on the actual number of access objects.

[0046] The terminal hardware includes a power sampling circuit, a main control processing circuit, an inter-module communication management circuit, an expansion module identification circuit, and a memory.

[0047] The power sampling circuit is used to receive external input power and to distribute power to the terminal hardware itself and its various extended functional modules. The power sampling circuit may include input protection, voltage conversion, and branch power supply control sections to ensure that the terminal hardware and extended functional modules can maintain stable operation even when there are voltage fluctuations or changes in the number of connected devices in the outdoor communication cabinet.

[0048] The main control processing circuit, as the main control unit of the terminal, is used to perform functions such as expansion module identification, function configuration generation, interface resource mapping, multi-source status data processing, and linkage control strategy execution. The main control processing circuit can adopt a structure that combines a processor and a memory, wherein the memory is used to store the function configuration table, linkage rule table, status record information, and abnormal event log.

[0049] The inter-module communication management circuit is used to maintain data interaction between the terminal hardware and the extended functional modules. This inter-module communication management circuit can adopt a unified internal bus structure. After different modules are connected to the unified expansion interface 2, the terminal hardware uniformly schedules the data transmission order and data sending / receiving process between modules, avoiding resource conflicts caused by the independent operation of each extended functional module.

[0050] The expansion module identification circuit is used to identify the functional module type of each expansion module during the terminal power-on initialization phase. The expansion module identification circuit can determine the specific type of the currently configured module by reading the pin status corresponding to each unified expansion interface 2, or by reading the identification code output by the expansion module identification circuit in the expansion module.

[0051] In this embodiment, the terminal hardware is pre-configured with multiple unified expansion interfaces 2. Each unified expansion interface 2 includes a power pin, a type identification pin, and a data bus pin. The power pin provides power to the expansion function modules, the type identification pin transmits the type information of the expansion function modules to the terminal hardware, and the data bus pin enables data communication between the terminal hardware and the expansion function modules. Standardization through the unified expansion interfaces 2 allows different types of expansion function modules to access the same terminal hardware platform while maintaining mechanical structural compatibility.

[0052] After the terminal is powered on, the main control processing circuit, in cooperation with the expansion module identification circuit, sequentially polls each unified expansion interface 2, reads the type identification information of each expansion location one by one, and determines the type of the expansion function module currently set in each expansion location based on the read type identification information, so as to form the expansion module identification result of the current terminal. The expansion module identification result is used to reflect the actual functional module combination status of the current terminal.

[0053] After obtaining the expansion module identification results, the main control processing circuit generates a function configuration table matching the current function module combination state based on the expansion function module type corresponding to each expansion location. Specifically, this includes: pre-saving resource description templates corresponding to different expansion function module types in the memory; each resource description template at least records the interface type, number of available interfaces, function channel numbering rules for each interface, external terminal block allocation rules, and the types of linkage control resources that can participate in the linkage control; the main control processing circuit reads the expansion module identification results according to the expansion location numbering order and matches the expansion function module type identified at each expansion location with the stored... The system searches for and matches the corresponding resource description template in the device. Upon successful matching, it extracts the resource parameters from the template and combines them with the current expansion location number. Then, it writes the functional module type, the number of interfaces provided by the functional module, the logical number of each interface channel, the corresponding external terminal block number, and the linkage control resources provided by the functional module into the corresponding record in the function configuration table. If no valid expansion functional module is identified at a certain expansion location, an idle state information is written into the record corresponding to that expansion location. After completing the above matching and writing at all expansion locations, the main control processing circuit obtains a function configuration table that corresponds one-to-one with the current functional module combination state. The function configuration table includes at least the module location number, module type, number of available interfaces, number of connected external terminal blocks, and the resource category undertaken by each interface channel during linkage control. The resource category includes at least status input resources, control output resources, and alarm reporting resources. Since the function configuration table is based on the expansion module identification results, it accurately represents the actual expansion capabilities of the current terminal under the current site conditions.

[0054] After generating the function configuration table, the main control processing circuit further establishes an interface resource mapping relationship between the specific terminals on the external terminal block assembly and the actual functional channels of each extended function module, based on the module location, module type, number of available interfaces, and external terminal block number recorded in the function configuration table. This interface resource mapping relationship is used to clarify the module type and specific functional channel corresponding to each external terminal block under the current site configuration, enabling the terminal hardware to accurately determine the specific path through which each external device connects to the terminal. Since the interface resource mapping relationship is based on the function configuration table, its mapping result remains consistent with the current functional module combination state.

[0055] After establishing the interface resource mapping relationship, the main control processing circuit reads the resource categories of each interface channel loaded in the function configuration table. Based on the resource categories of each interface channel, the main control processing circuit classifies and identifies each interface channel in the function configuration table, and associates each classified interface channel with the corresponding external wiring terminals and actual functional channels in the interface resource mapping relationship. This determines the type of linkage task that each interface channel can undertake under the current site configuration and generates a linkage control resource configuration relationship that matches the current site configuration.

[0056] The process of generating a linkage control resource configuration relationship that matches the current site configuration includes: assigning interface channels identified as status input resource categories to a status input channel set, assigning interface channels identified as control output resource categories to a control output channel set, and assigning interface channels identified as alarm reporting resource categories to an alarm reporting channel set; then, based on the interface resource mapping relationship, determining the external device access path and function channel number corresponding to each interface channel in the status input channel set, control output channel set, and alarm reporting channel set, respectively, to form a task channel set configured for the current site.

[0057] After forming a task channel set configured for the current site, the main control processing circuit further determines each interface channel in the status input channel set as a linkage judgment input channel, each interface channel in the control output channel set as a linkage action output channel, and each interface channel in the alarm reporting channel set as a linkage alarm reporting channel, according to the processing order of status input, control output, and alarm reporting in the linkage control process. The linkage judgment input channel, the linkage action output channel, and the linkage alarm reporting channel are then written into the linkage control resource configuration relationship to form a linkage control resource configuration result that matches the current site configuration.

[0058] After establishing interface resource mapping relationships and linkage control resource configuration relationships, the terminal hardware enables the intelligent converged terminal to form an access structure and linkage control structure that matches the current site under the current functional module combination conditions, thereby achieving adaptive deployment for different site configurations. Specifically, after obtaining the interface resource mapping relationships and linkage control resource configuration relationships, the terminal hardware first retrieves the currently enabled module locations, number of interfaces, and resource category information from the functional configuration table; then, according to the interface resource mapping relationships, it binds external terminals, module function channels, and external devices one by one to form a device access table for the current site; next, based on the linkage control resource configuration relationships, it writes the status input channel, control output channel, and alarm reporting channel into the corresponding fields of the linkage rule table, so that each type of channel has a clear task division in linkage processing; after completing the binding and writing, the terminal hardware receives the status of each device according to the device access table and outputs control commands and alarm information according to the linkage rule table, thereby forming an access structure and linkage control structure consistent with the current site.

[0059] When the site configuration changes, only the extended functional modules in the corresponding extended locations need to be added, removed, or replaced. The terminal hardware can then re-execute the processes of functional module type identification, functional configuration generation, interface resource mapping establishment, and linkage control resource configuration establishment, thereby forming a terminal structure that matches the new site configuration. Since the terminal hardware in the main body remains unchanged, terminal function reconstruction and site re-adaptation can be completed without replacing the entire terminal body when the site configuration changes.

[0060] In this embodiment, corresponding extended functions are provided according to the equipment access requirements of different outdoor communication cabinet sites. The extended function module 100 includes at least one of the following: RS-485 module 4, Ethernet module 7, switch quantity acquisition module 5, and wireless communication module 6. Each extended function module 100 is connected to the terminal hardware through a unified extended interface 2, thereby establishing power supply and data communication connections. Through this design, the variable functions required by the site are no longer fixed on the terminal hardware, but are modularly carried by different extended function modules 100, enabling the same terminal hardware platform to combine different extended capabilities as needed.

[0061] Furthermore, each extended function module 100 can be equipped with an extended module identification circuit and an interface adaptation circuit. The extended module identification circuit is used to output function module type information to the terminal hardware, so that the terminal hardware can identify the type and quantity of currently selected configuration modules during the power-on initialization phase. The interface adaptation circuit is used to convert the external device interface level, acquisition signal, or wireless signal into a data format that can be uniformly processed by the terminal hardware according to the specific function of the module. Thus, the terminal hardware can automatically establish the current terminal's function configuration table and interface resource mapping relationship by reading the function module type information without changing the overall hardware architecture.

[0062] The RS-485 module 4 is equipped with an expansion module identification circuit and an interface adapter circuit, and has multiple RS-485 communication interfaces.

[0063] To further illustrate the terminal arrangement and number of interfaces of RS-485 module 4, such as Figure 3 As shown, the RS-485 module can be configured with multiple channels and can be equipped with status indicators such as operation and communication. In this embodiment, a single RS-485 module 4 is equipped with four RS-485 communication interfaces for connecting serial devices such as switching power supply modules, battery monitoring modules, electricity meters, fan controllers, and air conditioning controllers. For outdoor communication cabinet sites with a large number of serial devices, two or more RS-485 modules 4 can be configured simultaneously.

[0064] The Ethernet module 7 is equipped with an expansion module identification circuit, an interface adaptation circuit, and an Ethernet communication interface. It is used to upload site status information, abnormal alarm information, and event logs processed by the terminal hardware to the remote monitoring platform, and also to receive configuration management commands issued by the remote monitoring platform. The Ethernet module 7 and the terminal hardware exchange uploaded data, transmitted data, and status confirmation data through a unified expansion interface 2.

[0065] The switch quantity acquisition module 5 is equipped with an expansion module identification circuit, an interface adapter circuit, and multiple switch quantity acquisition channels. In this embodiment, the switch quantity acquisition module 5 can be used to access access control status, equipment alarm information, etc. After converting the acquired information, the switch quantity acquisition module 5 forms standardized acquisition data and uploads it to the terminal hardware.

[0066] The wireless communication module 6 is equipped with an expansion module identification circuit, an interface adaptation circuit, and a wireless transceiver circuit, used to connect to wireless detection nodes in the cabinet auxiliary area, side cabinet area, or locations where wiring is inconvenient. Through the wireless communication module 6, remote door magnets, remote temperature points, or other auxiliary detection nodes can be incorporated into unified monitoring without changing the overall hardware structure of the terminal itself.

[0067] In this embodiment, the linkage control logic of the terminal hardware is executed according to the processing chain of multi-source access → status aggregation → comprehensive judgment → linkage decision → control output → alarm. Specifically, as follows: Figure 4 As shown: Step 1: The terminal hardware acquires the operating status of the switching power supply module, battery monitoring module, fan controller, and air conditioner controller, as well as the temperature and humidity detection component and water level detection component through the RS-485 module 4; acquires the alarm information of each device through the switch quantity acquisition module 5; and acquires the status of the wireless detection nodes in the auxiliary area through the wireless communication module 6.

[0068] Step 2: The terminal hardware forms a multi-source status set of the rack at the current moment from the above status data, and determines the source and ownership of each status data according to a preset function configuration table. If a certain type of module is not selected for configuration, the corresponding status item will not participate in the current terminal's linkage strategy calculation.

[0069] Step 3: The terminal hardware performs a comprehensive judgment on the multi-source state set according to the linkage rule table. In this embodiment, the linkage rule table includes at least a high-temperature linkage rule, a water level linkage rule, and an abnormal door opening linkage rule. The high-temperature linkage rule can specify that when the temperature inside the cabinet exceeds a first threshold, a fan start or speed adjustment command is output; when the temperature inside the cabinet exceeds a second threshold and the temperature does not recover after the fan runs, an air conditioner start command is output and a high-temperature alarm is reported simultaneously. The water level linkage rule can specify that when the water level is abnormal, a water level alarm is immediately reported and protection control is executed. The abnormal door opening linkage rule can specify that when the access control status changes and an environmental abnormality exists simultaneously, an abnormal event log is recorded and reported to the remote monitoring platform.

[0070] Step 4: The terminal hardware outputs the linkage decision results to the corresponding external devices through the corresponding extended function modules 100. For example, it outputs start or speed adjustment commands to the fan controller and puts the air conditioner into operation commands to the air conditioner controller through the RS-485 module 4; and it outputs abnormal alarm information and event logs to the remote monitoring platform through the Ethernet module 7.

[0071] Step 5: After the control output is completed, the terminal hardware continues to receive status data uploaded by each module and re-evaluates the effect of the linkage control output.

[0072] This embodiment provides the following three personalized configuration examples.

[0073] refer to Figure 6 As shown, the first type of site configuration is a basic outdoor communication cabinet suitable for a small number of devices. This site configuration includes one RS-485 module 4 and one industrial control module, which mainly connect to the switching power supply module, battery monitoring module, temperature sensor, and water level sensor.

[0074] refer to Figure 7 As shown, the second type of site configuration is suitable for standard outdoor communication cabinets that require remote wired networking. This site configuration includes an RS-485 module 4, an industrial control module, and an Ethernet module 7. In addition to basic status acquisition and linkage control, it also enables wired networking with a remote monitoring platform based on the Ethernet module 7.

[0075] refer to Figure 5 , Figure 8 As shown, the third type of site configuration is suitable for extended outdoor communication cabinets with auxiliary side cabinets or remote monitoring points. This site configuration includes a carrier communication module 3, an RS-485 module 4, a switch quantity acquisition module 5, a wireless communication module 6, and an Ethernet module 7, enabling access to multiple serial port devices, environmental quantity acquisition, wired upload, and wireless auxiliary monitoring point access.

[0076] As can be seen from the above site configuration, the intelligent converged terminal of the present invention is not a fixed-function device, but rather a combination of functional modules based on the access requirements of different sites on the basis of a unified terminal hardware platform, thereby achieving flexible deployment for truly outdoor communication cabinet-specific scenarios.

[0077] In this embodiment, in order to further illustrate the joint debugging effect of the modular and scalable intelligent fusion terminal of the present invention under different functional module combination configurations, the joint debugging and verification of the prototype's extended module identification, status acquisition, linkage control and remote reporting capabilities in a typical outdoor communication cabinet application scenario were carried out. The test results are shown in Table 1.

[0078] Table 1 Prototype Debugging and Testing Record

[0079] As shown in Table 1, the intelligent fusion terminal described in this invention can complete the tasks of identifying, collecting status data, implementing linkage control, and reporting alarms corresponding to the current site configuration under different combinations of the 100 extended function modules. In addition to the above-mentioned functional integration testing, an insulation withstand voltage test can be performed on the prototype to verify the terminal's operational stability under electrical stress and electromagnetic interference conditions. In the basic configuration, the terminal can stably and continuously collect data on the switching power supply, battery, temperature, humidity, and water level without generating false alarms during long-term operation. Under high-temperature triggering conditions, the terminal can sequentially execute actions such as fan start-up and air conditioner operation based on temperature thresholds and equipment operating status, and synchronously generate alarm information under abnormal conditions. In scenarios of abnormal water levels and abnormal remote wireless nodes, the terminal can promptly complete anomaly detection and information reporting. Under the mixed configuration of multi-functional modules, the terminal hardware can complete the identification of extended modules, generation of function configuration tables, and establishment of interface resource mapping in a short time. This demonstrates that the modular structure of the terminal hardware and extended function modules 100 enables flexible deployment and stable joint debugging according to different site configurations, thereby verifying the applicability and scalability of the invention in outdoor communication cabinet power environment monitoring and equipment linkage control scenarios.
