In emergency situations, when officers need to retrieve their equipment, they may not be able to immediately activate their body cameras to record the proceedings. Furthermore, police equipment may be lost during duty. Utility Model Content

[0003] The main objective of this utility model is to overcome the defects existing in the above-mentioned background technology and provide a police belt, a police belt front end system, and a police belt management system.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A police belt, comprising:

[0006] The belt itself has multiple fixing points for police equipment;

[0007] A metal sensing module is installed in the fixed position of each police equipment to detect the pulling action of the corresponding police equipment. The metal sensing module includes an inductor coil and a signal conversion unit. It senses the displacement of the metal equipment through electromagnetic coupling effect and generates a signal that the equipment has been pulled out, so as to realize real-time monitoring of the equipment pulling action.

[0008] A near-field communication module, connected to the metal sensing module, is used to send a notification to the law enforcement recorder via wireless communication when a pulling action is detected.

[0009] Furthermore, the belt body is equipped with multiple equipment protective sleeves, which form the fixing positions for the police equipment.

[0010] Furthermore, the metal sensing module is attached and fixed to the equipment protective cover by adhesive or sewing.

[0011] Furthermore, the multiple police equipment fixing positions include various types such as handcuff fixing positions, tear gas spray fixing positions, baton fixing positions, high-intensity flashlight fixing positions, and pistol fixing positions.

[0012] Furthermore, the metal sensing module includes a PCB frequency detection component, an inductor signal digital converter, a main control module, and a communication and protocol module connected in sequence. The PCB frequency detection component includes an LC oscillation circuit, with its inductor coil positioned close to a fixed position on the police equipment to sense the displacement of the metal parts of the equipment and trigger a frequency change in the LC oscillation circuit based on the change in inductance value. The inductor signal digital converter converts the frequency change into a digital signal and transmits it to the main control module. The main control module sends a signal indicating that the equipment has been pulled out to an external device via Bluetooth communication through the communication and protocol module.

[0013] Furthermore, the near-field communication module adopts a Bluetooth communication module.

[0021] This utility model has the following beneficial effects:

[0022] This invention provides a police belt that integrates metal sensing modules at multiple police equipment mounting points to monitor the removal of equipment in real time. Utilizing electromagnetic coupling, it detects the displacement of the metal equipment and triggers a signal. In conjunction with a near-field communication module, this signal is sent to the law enforcement recorder, enabling immediate feedback on the equipment's usage status and providing early warning of loss, thus improving the security of equipment management during law enforcement. The multiple equipment mounting points can coordinate with a single law enforcement recorder in a multi-to-one manner.

[0023] This utility model also provides a police belt front-end system and a police belt management system, which link a police belt with real-time monitoring capabilities with a law enforcement recorder.

Therefore, they should not be construed as limitations on this utility model.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] See Figure 1 This utility model provides a police belt, comprising: a belt body 5, integrating multiple police equipment fixing positions; a metal sensing module 4, disposed within each police equipment fixing position, with each fixing position equipped with an independent metal sensing module 4 for detecting the pulling action of the corresponding police equipment; the metal sensing module 4 includes an inductor coil and a signal conversion unit, sensing the displacement of the metal equipment through electromagnetic coupling effect and generating a signal indicating that the equipment has been pulled out, thereby achieving real-time monitoring of the equipment pulling action; and a near-field communication module, connected to the metal sensing module, for wirelessly notifying a law enforcement recorder (an external device) when a pulling action is detected. The belt body 5, through the metal sensing module 4 disposed within each police equipment fixing position and the near-field communication module, achieves real-time monitoring and signal transmission of the equipment pulling action.

[0033] In a preferred embodiment, the belt body 5 is provided with a plurality of equipment protective covers, which form the fixing position of the police equipment.

[0034] In a preferred embodiment, the metal sensing module is attached and fixed to the equipment protective cover by adhesive or sewing.

[0035] In some embodiments, the plurality of police equipment fixing positions include multiple types selected from handcuff fixing position 1, baton fixing position 2, tear gas spray fixing position 3, high-intensity flashlight fixing position, and pistol fixing position. Each fixing position is independently equipped with a metal sensing module 4 for detecting the withdrawal action of the corresponding equipment and transmitting signals in real time via a near-field communication module.

[0036] See Figure 2In a preferred embodiment, the metal sensing module includes a PCB frequency detection component, an inductor signal digital converter, a main control module, and a communication and protocol module connected in sequence. The PCB frequency detection component includes an LC oscillation circuit, with the inductor coil of the LC oscillation circuit positioned close to a fixed position on the police equipment to sense the displacement of the metal parts of the police equipment and trigger a frequency change in the LC oscillation circuit based on the change in inductance value. The inductor signal digital converter converts the frequency change into a digital signal and transmits it to the main control module. The main control module sends a signal indicating that the equipment has been pulled out to the law enforcement recorder via Bluetooth communication through the communication and protocol module.

[0037] See Figure 3 In application, the metal sensor modules at the fixed positions of each piece of equipment are bound to the law enforcement recorder in a many-to-one binding mode. Multiple metal sensor modules are associated with the same law enforcement recorder, enabling centralized monitoring and signal transmission of multiple equipment withdrawal actions.

[0038] In a preferred embodiment, the near-field communication module is a Bluetooth communication module.

[0039] This utility model embodiment also provides a police belt front end system, including: the police belt; a law enforcement recorder, which is communicatively connected to the near-field communication module of the police belt and connected via a wireless network.

[0040] The law enforcement recorder has a built-in positioning module, communication module, and audio / video acquisition unit. During operation, upon receiving a signal from the metal detector indicating that the equipment has been removed, the recorder automatically triggers the audio / video recording function and uploads the marked event data in real time via a wireless network.

[0041] This police belt integrates metal sensing modules at multiple fixed points on police equipment to monitor the removal of equipment in real time. It uses electromagnetic coupling to detect the displacement of metal equipment and trigger a signal. In conjunction with a near-field communication module, it sends a signal to notify the law enforcement recorder to start, enabling real-time feedback on the usage status of police equipment and early warning of loss on the management platform. This achieves the effect of equipment management and behavior tracing during law enforcement.

[0042] This utility model embodiment also provides a police belt management system, including: the aforementioned police belt front-end system; and a law enforcement recorder connected to the police belt front-end system via a wireless network (such as WIFI, 4G or 5G network) for receiving information reported by the law enforcement recorder to perform management operations.

[0043] In some applications, the management platform can display real-time video and audio footage and police officer location information, and simultaneously trigger coordinated response commands from surrounding devices to achieve automated scheduling and data traceability of the law enforcement process.

[0044] The application of this utility model is further described below.

[0045] Police belts include mounting points for commonly used police equipment such as handcuffs, tear gas spray, batons, high-intensity flashlights, and pistols, preferably using equipment protective sleeves. Metal detection modules are attached to the equipment protective sleeves via adhesive or sewing to detect whether equipment has been removed and to facilitate near-field communication with the body camera. Each equipment protective sleeve is equipped with one metal detection module.

[0046] The police belt front-end system includes a police belt and at least one body camera. The body camera receives a draw signal from a metal detector module, automatically activates audio and video recording, and can establish a communication connection with a management platform. Multiple metal detector modules on the police belt work collaboratively with the body camera in a multi-to-one manner.

[0047] The metal sensing module specifically includes a PCB frequency detection component, an inductor signal-to-digital converter, a main control module, and a communication and protocol module. The PCB frequency detection component is positioned close to the police equipment and contains an inductor coil. When the metal part of the police equipment approaches or moves away, the electromagnetic coupling effect between the metal and the inductor coil causes a change in the inductance value, which in turn causes a change in the oscillation frequency of the LC oscillation circuit included in the inductor signal-to-digital converter. The inductor signal-to-digital converter converts the inductance change into a digital signal and communicates with the main control module. The main control module controls the communication and protocol module to achieve Bluetooth communication with the law enforcement recorder, thereby detecting the removal of police equipment. In this case, the metal sensing module sends a signal indicating that the police equipment has been removed to the law enforcement recorder via Bluetooth.

[0048] When the body camera receives a signal from the metal detector indicating that police equipment has been retrieved, it automatically starts recording. Simultaneously, the body camera can report the incident to the management platform via Wi-Fi / 4G / 5G networks.

[0049] The police belt management system includes the police belt front-end system and management platform.

[0050] As an application, after receiving a report from the body camera, the management platform can receive and play back the live video footage from the body camera, displaying the real-time location of the police officer. As another application, the management platform can work with the body camera to collect evidence, using the video footage as a record for future reference. The management platform can also dispatch resources based on events reported by the body camera, for example, by issuing recording commands to nearby video devices connected to the management platform.

[0051] The above description, in conjunction with specific / preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various substitutions or modifications can be made to these described embodiments without departing from the concept of the present invention, and all such substitutions or modifications should be considered within the protection scope of the present invention.
