This results in complex deployment and difficult maintenance of onboard equipment. Furthermore, data transmission typically relies on a single network module, leading to insufficient network stability and poor real-time data transmission. In addition, existing onboard equipment often fails to continuously upload location information after the vehicle is turned off, resulting in a lack of vehicle status monitoring.

[0019] The present invention will be further described below with reference to the accompanying drawings. It should be noted that this embodiment is based on the present technical solution and provides detailed implementation methods and specific operation processes, but the protection scope of the present invention is not limited to this embodiment.

[0020] This embodiment provides a police intelligent vehicle-mounted device, such as... Figure 1-2 As shown, it includes a main control unit, a wireless communication module, a positioning module, an extended storage unit, an interface unit, and a power management module;

[0021] The main control unit is communicatively connected to the wireless communication module, positioning module, extended storage unit, and interface unit, respectively, and is used to manage and control the wireless communication module, positioning module, extended storage unit, and interface unit.

[0022] The power management module is electrically connected to the main control unit and is used to input power to the main control unit and to supply power to the wireless communication module, positioning module, extended storage unit and interface unit through the main control unit.

[0023] The wireless communication module includes at least two independent 5G communication modules that use different operator networks to enable remote wireless connection between the main control unit and the back-end platform for real-time transmission of information such as video image data, vehicle location information, and back-end platform commands.

[0024] The positioning module is specifically a single Beidou positioning module, used to realize the real-time collection of vehicle location information.

[0025] Extended storage units are used for data storage. For example... Figure 2As shown, the main control unit itself has a storage unit, which is the storage capacity of the main control unit itself. The storage capacity is fixed and is mainly used to store data information generated by the main control unit itself. The expansion storage unit is an accessible and replaceable storage unit used to expand the fixed memory capacity to meet the data storage needs of a large number of external devices.

[0026] The interface unit is used to connect with external devices (such as cameras, police lights, microphones, display devices, etc.) on police vehicles, and is used for inputting information from external devices to the main control unit and for the main control unit to output information or instructions to external devices.

[0027] The power management module has a built-in backup battery, which is electrically connected to the main control unit. The power management module is powered by the vehicle's power supply, and the backup battery allows the police intelligent vehicle-mounted equipment to continue operating even after the vehicle is turned off, enabling continuous uploading of vehicle location information.

[0028] Specifically, in this embodiment, the main control unit consists of an RK3588 chip and peripheral circuitry. It connects to the interface unit via HDMI, GRMII, etc.; to the 5G communication module via a USB 3.0 interface; to the single BeiDou positioning module via an RS232 interface; and to the extended storage unit via a USB 2.0 interface. The main control unit has a computing power of 6 TOPS and can process data from information received from external devices.

[0029] Specifically, this embodiment sets up two 5G communication modules, and the main control unit controls the switching between the two 5G communication modules to ensure the stability of data transmission.

[0030] The positioning module transmits the acquired positioning information to the wireless communication module via the main control unit, and then sends it to the backend platform.

[0031] The main control unit periodically stores various data acquired by external devices connected to the interface unit, such as video, images, and device status information, in the extended storage unit. Once data expires, the extended storage unit automatically overwrites the information, sorting it by storage time. The main control unit can retrieve and view the information in the extended storage unit in real time.

[0032] The interface unit has multiple interfaces such as network port, HDMI, USB 2.0 / USB 3.0 / Type-C interface, RS232 serial port, and UART serial port to adapt to external devices with different interfaces.

[0033] The power management module is connected to the vehicle's power supply via a 24-pin interface. During vehicle startup, the vehicle's power supply provides power to the power management module. The power management module is connected to the main control unit via an RS765-5 interface, using a voltage regulator chip to convert the input vehicle power voltage to achieve a wide voltage output, thereby powering all modules. The power management module has a built-in backup battery, which can continuously power the police intelligent vehicle-mounted equipment and upload vehicle location information when the vehicle is off.

[0034] In use, the aforementioned police intelligent vehicle-mounted equipment is installed on the police vehicle and connected to the vehicle's power supply. It is then connected to external devices such as the pan-tilt unit, police lights, and display screen on the police vehicle via an interface unit.

[0035] After the vehicle starts, the vehicle's power supply powers the equipment, and the wireless communication module automatically connects to the operator's network. The interface unit receives input data from external devices and sends it to the main control unit, which then stores the data in the extended storage unit. The main control unit processes the input data, stores the processing results in the extended storage unit, and dynamically switches between two 5G communication modules based on the strength of the operator's network signal to synchronously send the processed data to the backend platform. Alternatively, it can send the data to an external display device, allowing operators on the vehicle to view relevant video data and other information in real time.

[0036] After the vehicle is turned off, the main control unit switches to backup battery power. The positioning module collects location data (including latitude, longitude, speed, and direction) every 10 minutes. After obtaining the positioning information, the main control unit transmits it to the wireless communication module and uploads it to the backend platform via the 5G network. If the network is interrupted, the data is temporarily stored in the extended storage unit and will be retransmitted after the network is restored.

[0037] For those skilled in the art, various corresponding changes and modifications can be made based on the above technical solutions and concepts, and all such changes and modifications should be included within the protection scope of the claims of this utility model.
