[0002] As a key component of the monitoring system, surveillance cameras are usually installed at high places or in places that are difficult to observe directly to ensure full coverage of the monitoring area and to capture and transmit real-time video data. However, in actual use, these surveillance cameras and other edge devices may encounter accidental drops, especially in extreme cases such as severe weather conditions, earthquakes or human interference, causing the equipment to lose power or completely lose its normal working ability, interrupting the monitoring video stream, and seriously affecting the overall performance of the monitoring system.

[0003] Traditional monitoring systems cannot obtain the status information of the equipment in time after the equipment falls, resulting in delays in fault detection and difficulties in maintenance. In addition, although the method of relying on manual inspection can perform equipment inspection to a certain extent, it is difficult to detect and respond to equipment falls in real time due to its low efficiency and reliance on regular inspections. Therefore, how to detect the falling status of the equipment in real time is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In order to more clearly illustrate the embodiments of the present invention, the following briefly introduces the drawings required for use in the embodiments. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0043] With the widespread application of modern surveillance systems, higher requirements are placed on the stability and reliability of video surveillance equipment. As a key component of this system, surveillance cameras are usually installed at high places or in places that are difficult to directly observe to ensure full coverage of the surveillance area and to achieve real-time video data capture and transmission. The main task of these cameras is to ensure the safety of the surveillance area and provide clear video surveillance data for real-time monitoring and later viewing.

[0044] However, in actual use, these surveillance cameras and other edge devices face many potential risks and challenges. For example, the device may fall, especially in extreme cases such as severe weather conditions (such as storms, ice and snow), earthquakes, or human interference. Once the device falls, the monitoring video stream will be interrupted and the status of the device cannot be monitored, which seriously affects the overall performance of the monitoring system. In this case, the monitoring system cannot know in real time whether the device has fallen, resulting in a blind spot in the detection of device failures. Traditional monitoring systems may not be able to obtain device status information in time after the device falls, resulting in delays in fault detection and difficulties in maintenance. Equipment maintenance and inspection often rely on manual inspections. Although this method can detect the status of the device to a certain extent, it is inefficient and relies on regular inspections, and cannot detect and respond to device falls in real time. Manual inspections may not cover all device locations, resulting in potential problems being ignored.

[0045] In order to solve the above technical problems, the present invention provides a device for detecting the state of an equipment, which can realize real-time monitoring of the falling state of the equipment and improve the detection efficiency.

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. The device state detection device provided in the embodiment of the present invention may include:

[0048] A wireless radio frequency identification tag is located in the metal enclosure and mounted on the target device, and is used to generate a radio frequency signal corresponding to the target device; the metal enclosure is used to shield the radio frequency signal; when the target device falls, the wireless radio frequency identification tag is exposed from the metal enclosure;

[0049] The wireless radio frequency detection terminal is located in the working area of ​​the target device and is used to read and analyze the radio frequency signal when the wireless radio frequency identification tag is exposed to obtain the drop location and information of the target device.

[0050] It should be noted that Radio Frequency Identification (RFID) technology is a non-contact two-way data communication through radio frequency, which uses radio frequency to read and write recording media (electronic tags or radio frequency cards) to achieve the purpose of identifying targets and exchanging data. Radio frequency tags can be selected for metal surfaces and closed environments. Each tag can contain a unique identification code and basic device information. Among them, the identification code corresponds to the device one by one. Basic device information can include the serial number, manufacturer, model, location, person in charge, person in charge contact information and other information of the target device.

[0051] Figure 1 The structure diagram of the wireless radio frequency identification tag in the device state detection device provided by the embodiment of the present invention. Figure 1 As shown, the target device is a surveillance camera as an example, and the wireless radio frequency identification tag 1 is located in the metal enclosure structure and installed on the target device, and can generate a radio frequency signal corresponding to the target device. When the target device is not dropped, the metal enclosure structure can maintain the state of shielding the radio frequency signal. When the target device is dropped, the wireless radio frequency identification tag 1 can be exposed from the metal enclosure structure.

[0052] Figure 2 The schematic diagram of the framework of the device state detection device provided by the embodiment of the present invention. Figure 2 As shown, the wireless radio frequency detection terminal 2 is located in the working area of ​​the target device, and can read and analyze the radio frequency signal of the wireless radio frequency identification tag 1 when the wireless radio frequency identification tag 1 is exposed to obtain the falling position and information of the target device. The detection range of the wireless radio frequency detection terminal 2 can fully cover the area where the target device is located, and has wireless communication capabilities. Taking the surveillance camera as an example, the present invention can select a suitable location in the monitoring area to install the wireless radio frequency detection terminal 2 to ensure that it covers the areas where all surveillance cameras that need to be monitored are located; when the surveillance camera falls, the wireless radio frequency identification tag 1 will be exposed, and the wireless radio frequency detection terminal 2 can read the tag information. It should be supplemented that the location information of the target device can be pre-built-in, and the falling position of the target device is the pre-built-in location information of the target device.

[0053] In the above-mentioned device status detection device provided by the embodiment of the present invention, the wireless radio frequency identification tag is installed on the target device and arranged in the metal closed structure, and the wireless radio frequency identification technology is used to realize real-time monitoring of the falling state of the target device. When the target device falls, the wireless radio frequency identification tag will be exposed from the metal closed structure, and the wireless radio frequency detection terminal can read the radio frequency signal in real time. This instant feedback mechanism can significantly improve the detection efficiency of the target device falling, improve the reliability and maintenance efficiency of the target device, and can solve the problem of the monitoring blind area caused by the inability of the fallen device to provide status feedback, thereby reducing the impact of equipment failure on system security.

[0054] Furthermore, in a specific implementation, in the above-mentioned device state detection device provided in the embodiment of the present invention, if Figure 2 As shown, the system may further include: a management terminal 3, which is used to receive the drop position and information of the target device transmitted by the wireless radio frequency detection terminal 2, and generate an alarm signal.

[0055] In implementation, the wireless radio frequency detection terminal 2 can communicate data with the management terminal 3. The data transmission format may include binary, JSON (JavaScript Object Notation), Extensible Markup Language (XML), etc. The data transmission protocol may include Hypertext Transfer Protocol Secure (HTTPS), Hypertext Transfer Protocol (HTTP), Message Queuing Telemetry Transport (MQTT), etc.

[0056] When the target device falls, the RFID tag 1 will be exposed, and the RFID detection terminal 2 can read the RF signal immediately, and report the analyzed drop position and information of the target device to the management terminal 3 through the network. The management terminal 3 can receive the drop position and information of the target device reported by the RFID detection terminal 2, and provide target device status monitoring, data analysis and alarm functions, generate alarm notifications, such as notifying relevant maintenance personnel to handle by email, SMS, push notifications, etc. This can ensure effective real-time response, reduce the time of equipment downtime due to failure, and reduce maintenance costs and equipment replacement costs. In addition, the real-time alarm mechanism and data analysis function provide a comprehensive grasp of the device status, provide a strong guarantee for system security, help discover potential problems, carry out preventive maintenance in advance, and further optimize the configuration of maintenance resources.

[0057] Furthermore, in a specific implementation, in the above-mentioned device state detection apparatus provided in an embodiment of the present invention, the RFID tag 1 can be installed on the base of the target device; or, the RFID tag 1 can be installed on a fixed contact connected to the base of the target device.

[0058] In implementation, the RFID tag 1 can be fixedly mounted on the base of the target device or a fixed contact to ensure that the RFID tag 1 is enclosed in normal working conditions and does not affect the normal use of the device. It should be noted that the fixed contact is any immovable object or structure connected to the base of the target device. The fixed contact may include a metal bracket or other infrastructure that can provide stable support. Installing the RFID tag 1 in these fixed contacts ensures that the RFID tag 1 will not be disturbed during normal operation and can be exposed for detection after the device falls.

[0059] In the present invention, the installation position of the wireless radio frequency identification tag 1 is carefully selected and designed so that it can work effectively in various working conditions and can operate stably even in complex environments, avoiding the blind spot problem caused by the hidden location of the device.

[0060] Furthermore, in a specific implementation, in the above-mentioned device state detection device provided in the embodiment of the present invention, if Figure 1 As shown, the metal enclosed structure may include: an uncovered metal shell box 11, an electromagnetic cover plate 12 and at least one spring 13; the electromagnetic cover plate 12 is located on the top of the uncovered metal shell box 11; the spring 13 and the wireless radio frequency tag are located inside the uncovered metal shell box 11, and one end of the spring 13 is installed at the bottom of the metal shell box.

[0061] In practice, the RFID tag 1 can be placed in the metal enclosure structure. When the metal enclosure structure is in a closed state, that is, the uncovered metal shell box 11 and the electromagnetic cover plate 12 are in full contact, the RFID tag 1 cannot be identified by the RFID detection terminal 2, and the RF signal will be shielded.

[0062] Furthermore, in the specific implementation, in the above-mentioned device status detection device provided in the embodiment of the present invention, the wireless radio frequency identification tag 1 can be a non-metal-resistant wireless radio frequency identification tag 1. The signal transmission of this type of tag will be shielded in a metal environment, so under normal use, the radio frequency signal may not be effectively transmitted. This choice is to cooperate with the metal shielding design of the base to ensure that the wireless radio frequency identification tag 1 can only be effectively read when the device falls.

[0063] like Figure 2As shown, the uncovered metal housing box 11, the electromagnetic cover plate 12 and the spring 13 can all be made of metal materials; the electromagnetic cover plate 12 has magnetism when powered on and loses magnetism when powered off; the electromagnetic cover plate 12 is integrated with the target device. There can be at least two springs.

[0064] When the target device has not fallen, the electromagnetic force cover 12 is powered on, the uncovered metal shell box 11 and the electromagnetic force cover 12 attract each other under the action of electromagnetic force, and the electromagnetic force is greater than the elastic force of the spring 13, forming a shield; the radio frequency signal generated by the wireless radio frequency identification tag 1 is shielded in the closed space formed by the uncovered metal shell box 11 and the electromagnetic force cover 12, and cannot penetrate the metal base; the wireless radio frequency detection terminal 2 cannot read the radio frequency signal.

[0065] When the target device falls, the electromagnetic force cover 12 is in a power-off state and loses the electromagnetic force; under the action of the spring 13, the uncovered metal shell box 11 is separated from the electromagnetic cover; when the uncovered metal shell box 11 is separated from the electromagnetic cover, a gap is generated, and the gap exposes the wireless radio frequency identification tag 1; the radio frequency signal is transmitted to the wireless radio frequency detection terminal 2.

[0066] It should be noted that the wireless RFID tag 1 can be divided into two types, one is active, which can actively transmit the tag's RFID signal; the other is passive and does not require a power source. When the wireless RFID tag 1 is exposed, the signal sent by the RFID signal recognition end is reflected by the passive wireless RFID tag 1, thereby achieving identification.

[0067] The present invention uses the above-mentioned wireless radio frequency technology to realize automatic monitoring, ensuring that the monitoring system can respond quickly when the equipment falls, avoiding the monitoring blind spot caused by the equipment falling, thereby enhancing the overall security of the system, reducing the dependence on manual inspections, and improving the intelligence level of the monitoring system. Compared with traditional manual inspections, the present invention uses a more efficient and reliable monitoring method, greatly reducing the complexity and labor costs of equipment maintenance, while improving the overall stability and response speed of the system.

[0068] Furthermore, in a specific implementation, in the above-mentioned device status detection apparatus provided in an embodiment of the present invention, the wireless radio frequency identification tag 1 can also be integrated into the circuit of the target device; the metal enclosing structure can be a metal object of the target device itself, and the wireless radio frequency identification tag 1 is located inside the metal object and enclosed by the metal object; the metal object is in a closed state when the target device has not fallen; and the metal object is in an open state when the target device has fallen.

[0069] In practice, the RFID tag 1 can be set on the base of the target device or a fixed contact object, or integrated with the internal circuit of the target device, and shielded by the target device's own protective structure to ensure that the RF signal cannot be transmitted when the target device is working normally. When the target device falls and is hit, the protective structure pops open, exposing the RF signal.

[0070] Furthermore, in a specific implementation, the above-mentioned device status detection apparatus provided in the embodiment of the present invention may also include: an acceleration sensor, installed on the target device; the acceleration sensor includes a mass block and a controller; the acceleration sensor is used to detect acceleration data generated by the displacement change of the mass block when the target device falls, and when the acceleration data exceeds the acceleration threshold, the wireless radio frequency identification tag 1 is triggered to be exposed through the controller.

[0071] In implementation, the accelerometer can be a micro-electro-mechanical system (MEMS) accelerometer, which includes a set of micro-mass blocks and spring devices, and can sense acceleration changes in different directions. The accelerometer can be fixed inside or on the base of the target device to ensure that it can accurately capture acceleration data when the target device moves.

[0072] When the target device is dropped or violently shaken, the mass block of the acceleration sensor will be displaced due to gravity and changes in motion state, and the circuit inside the sensor will detect this change. Once the preset acceleration threshold is detected, the sensor will immediately trigger the wireless radio frequency identification tag 1 to expose or actively send a signal through the microcontroller.

[0073] Furthermore, in a specific implementation, the above-mentioned device state detection apparatus provided in the embodiment of the present invention may also include: a pressure sensor installed on the target device, for sensing whether the target device is in contact with the ground.

[0074] In implementation, the pressure sensor may be a thin film pressure sensor, which is composed of a diaphragm made of conductive material and a resistor network, and can sense changes in applied pressure. The pressure sensor can be installed at the base or contact point of the target device, and can directly sense whether the target device is in contact with the ground.

[0075] Under normal working conditions, the sensor maintains a certain pressure value. When the target device falls and contacts the ground, the pressure sensor senses the instantaneous pressure change. When the pressure reaches a threshold, such as the pressure when contacting the ground, the pressure sensor outputs a signal, triggering the wireless radio frequency identification tag 1 to be exposed or actively send a signal, notifying the management end that the target device status has changed.

[0076] Furthermore, in a specific implementation, the above-mentioned device status detection apparatus provided in the embodiment of the present invention may also include: an airbag component filled with an inert gas (such as nitrogen), which is arranged in a metal closed structure and is used to release gas and generate impact force when the target device falls.

[0077] In implementation, the airbag component filled with gas can be made of elastic material and can expand rapidly to generate sufficient force. An ignition device can be set inside the airbag component, connected to an accelerometer or other triggering device, which will be activated when the device falls. When the device falls, the accelerometer detects violent movement and triggers the airbag component, which expands rapidly, releases gas and generates impact force. This impact force can open the cover of the metal base, exposing the wireless radio frequency identification tag 1, thereby allowing the signal to be read. This further ensures effective shielding of the radio frequency signal when the target device is in a normal state, and at the same time, after the device falls, the exposure of the gap can enable the radio frequency signal to resume transmission.

[0078] In the above embodiments, the device state detection apparatus is described in detail. Based on the same inventive concept, the embodiments of the present invention also provide corresponding embodiments of the detection method and monitoring system of the device state detection apparatus.

[0079] Figure 3 Flowchart of the detection method of the device status detection device provided by the embodiment of the present invention. The detection method of the device status detection device provided by this embodiment is as follows: Figure 3 As shown, the specific steps include:

[0080] S301. When the target device has not fallen, a metal enclosed structure is used to shield a radio frequency signal corresponding to the target device generated by a radio frequency identification tag; the radio frequency identification tag is located in the metal enclosed structure and is installed on the target device.

[0081] In a possible implementation, the radio frequency identification tag has the characteristic that the signal is shielded in a metal environment. The radio frequency identification tag is arranged in a metal enclosure structure, which may include three parts. First, the first part is an electromagnetic force cover plate made of metal, which can have magnetism when powered on and lose magnetism when powered off. Secondly, the second part is an uncovered metal shell box, which is combined with the electromagnetic force cover plate to form a whole. Inside the uncovered metal shell box, there may be at least two force-storing springs. In addition, the third part is a radio frequency identification tag placed in the uncovered metal shell box. When the target device is installed normally, the electromagnetic force cover plate and the uncovered metal shell box will attract each other to form a shielding effect, so that the signal of the radio frequency identification tag cannot penetrate the metal base, and thus cannot be received by the detection terminal.

[0082] S302: When the target device falls, the radio frequency identification tag is exposed from the metal enclosure structure.

[0083] In a possible implementation, when the target device falls, the electromagnetic force is lost, and the force of the spring causes the electromagnetic cover to separate from the uncovered metal housing box, thereby exposing the wireless radio frequency identification tag so that its signal can be transmitted to the detection terminal.

[0084] S303: When the RFID tag is exposed, a RFID detection terminal is used to read and analyze the RFID signal to obtain the drop location and information of the target device.

[0085] In a possible implementation, the wireless RF detection terminal can be placed in a place that can effectively cover the monitoring area to ensure that the signal emitted from the exposed tag can be read after the target device falls. The placement of the wireless RF detection terminal should take into account the possible falling area of ​​the target device to ensure comprehensive monitoring.

[0086] In the detection method of the above-mentioned device status detection apparatus provided by the embodiment of the present invention, by executing the above-mentioned steps S301 to S303, the wireless radio frequency identification tag can be installed on the target device and set in the metal closed structure, and the wireless radio frequency identification technology can be used to realize real-time monitoring of the falling state of the target device. When the target device falls, the wireless radio frequency identification tag will be exposed from the metal closed structure, and the wireless radio frequency detection terminal can read the radio frequency signal in real time. This instant feedback mechanism can significantly improve the detection efficiency of the target device falling, improve the reliability and maintenance efficiency of the target device, and can solve the problem of the monitoring blind area caused by the inability of the fallen device to provide status feedback, thereby reducing the impact of equipment failure on system security.

[0087] Since the embodiments of the detection method part correspond to the embodiments of the device state detection device part, the embodiments of the detection method part refer to the description of the embodiments of the device state detection device part, which will not be repeated here. And it has the same beneficial effects as the above-mentioned device state detection device.

[0088] Furthermore, in a specific implementation, the detection method of the device status detection apparatus provided in the embodiment of the present invention may further include: using a management terminal to receive the drop position and information of the target device transmitted by the wireless radio frequency detection terminal, and generating an alarm signal.

[0089] In implementation, the wireless RF detection terminal needs to have stable wireless communication capabilities and can transmit the read wireless RF identification tag information to the management end in a timely manner. The terminal's signal reception capability and data transmission rate directly affect the accuracy and response time of the detection. After receiving the drop location and information of the target device transmitted by the wireless RF detection terminal, the management end generates an alarm signal.

[0090] It should be added that the data transmission mechanism from the wireless radio frequency detection terminal to the management end may include transmission protocols, data formats, and network security measures. Among them, network security measures may include encrypting data using the Transport Layer Security (TLS) protocol. When implemented, data may be encrypted end-to-end before being sent to ensure that only the recipient can decrypt and access the data content.

[0091] The management end may have the function of processing and analyzing the drop event data, including counting drop events, analyzing frequency, processing data, generating reports and formulating maintenance recommendations. Among them, basic statistics such as the average, standard deviation, maximum and minimum values ​​can be calculated to understand the overall trend of the device drop events; the frequency of drop events in different time periods can be counted to identify high-risk periods. It is also possible to identify abnormal events based on set thresholds, such as sudden changes in acceleration sensor data, and use the z-score method to detect abnormal values ​​and identify abnormal behavior of the device. The processed data may include device status data, drop event data, environmental data, historical maintenance record data, performance indicators, etc.; the device status data may include sensor data, operating time and first data value. Sensor data may include real-time monitoring data such as acceleration, temperature, humidity, voltage, vibration, etc.; operating time refers to the cumulative operating time and working cycle of the device; the first data value is to evaluate the use of the device, monitor the health of the sensor in real time, quickly identify potential faults, optimize maintenance plans, and reduce unexpected downtime. Drop event data may include drop records, recovery status after drop, and second data value. The drop record is the time, location, cause and equipment status of each drop event; the recovery status after the drop is to determine whether the equipment has resumed normal operation, the time required for recovery and the maintenance measures; the second data value is to track and analyze the causes and consequences of equipment drops, formulate preventive measures, improve installation and maintenance strategies, and improve equipment safety. Environmental data can include weather data, earthquake data and third data value. Weather data can include environmental conditions such as rainfall, wind speed, and temperature that affect equipment performance; earthquake data can include the time and magnitude of earthquakes and their potential impact on equipment; the third data value is to understand the impact of the environment on equipment performance, adjust operating conditions, optimize equipment layout, and improve equipment adaptability and stability. Historical maintenance record data can include maintenance and overhaul records, fault records and fourth data value. Maintenance and overhaul records are detailed maintenance, overhaul and replacement history, including when, what reasons, and what measures were taken; fault records are records of all fault events and their handling processes to analyze failure modes and frequencies; the fourth data value is to identify failure modes and frequencies, evaluate the effectiveness of maintenance strategies, and optimize resource allocation. Performance indicators can include equipment failure rate, mean repair time and fifth data value. The equipment failure rate refers to the number of failure events per unit time, which is used to evaluate the reliability of the equipment; the mean repair time refers to the average time it takes for the equipment to resume normal operation after a failure, which is used to evaluate maintenance efficiency; the fifth data value is to evaluate equipment reliability and maintenance efficiency and improve work.
