Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5 This utility model provides a technical solution: including a housing 1, with an operation panel 2 and an NFC sensing unit 3 connected to the front of the housing 1, a circuit board 4 connected to one side inside the housing 1, a main control chip 5, a data acquisition chip 6, a surface-mount temperature sensor 7, a protocol adapter module 8, a communication chip 9, a local diagnostic engine 10, a protective capacitor 11, and heat dissipation fins 12 connected to the top of the circuit board 4, a multi-protocol adapter board 13 connected to one side of the housing 1, a spare battery 14 connected to the bottom of the inner wall of the housing 1, and an external sound and light alarm connected to one side of the housing 1, with the main control chip 5 being a signal connection;

[0021] The main control chip 5 has a built-in storage unit and is responsible for overall coordination, data processing, logical judgment, protocol parsing, and diagnostic engine operation.

[0022] Reference Figure 3 As shown, the backup battery 14 is electrically connected to the main control chip 5, data acquisition chip 6, surface-mount temperature sensor 7, protocol adapter module 8, communication chip 9, local diagnostic engine 10, protection capacitor 11, and heat sink fins 12. A charging port 141 is provided on one side of the housing 1 corresponding to the backup battery 14. The backup battery 14 maintains the core function for a period of time when the main power supply fails. It is used in conjunction with a DC socket, which is a DC12V / 24V dual-terminal socket with dual power redundancy, supports main and backup power input, and automatic switching.

[0023] One side of the multi-protocol adapter board 13 includes an RJ45 network port, an RS485 bus interface, a fiber optic SFP slot, a Phoenix terminal interface, and a DC socket. The protocol adapter module 8 uses an FPGA + protocol library chip to achieve automatic protocol identification. It has a built-in corresponding protocol conversion chip and software stack. Through network port data → automatic matching of ONVIF / RTSP / proprietary protocol; RS485 data → automatic switching of Modbus / custom frame format, breaking the subsystem protocol barrier, and can be connected to mainstream security equipment without additional converters. The multi-protocol adapter board 13 is electrically connected to the circuit board 4.

[0024] A digital-to-analog converter (DAC) is connected to one side of the data acquisition chip 6, connecting the external monitoring sensor to the Phoenix terminal interface. This allows the external monitoring sensor to transmit monitoring information to the data acquisition chip 6, which then converts the data and transmits it to the main control chip 5. The information is then sent to the monitoring backend via the communication chip 9. The external monitoring sensors include current, voltage, temperature, humidity, and signal strength sensors. The communication chip 9 includes wired network (main) and 4G / 5G (backup) remote communication. It also works with the NFC sensing unit 3, integrating NFC / Bluetooth and other near-field technologies for easy connection and debugging by on-site personnel. At the same time, the device sends status query commands to each monitored device at set intervals, such as 1-5 minutes, using adapted protocols such as Ping, SNMPGet, and private protocol query commands. It reads the online status, CPU / memory utilization (if supported), and critical service status returned by the device, synchronously reads data from built-in / external sensors, and receives alarm information actively reported by the device.

[0025] This allows for the monitoring of equipment status, parameter readings, and diagnostic results, thereby assessing the overall health of the security system.

[0026] When an anomaly is detected (device offline, parameter exceeding threshold, fault diagnosed):

[0027] Triggering the audible and visual alarm (buzzer sounds, red light flashes) displays specific alarm information and preliminary diagnostic results on the touch screen. Through communication chip 8, the alarm information (including device identifier, abnormal phenomenon, collected data, preliminary diagnostic conclusion, and timestamp) is pushed to the cloud-based operation and maintenance management platform or the designated operation and maintenance personnel's mobile APP / SMS / email. The operation and maintenance personnel can remotely view the status of all devices, historical data, and alarm records through the management platform or APP; they can also remotely configure device parameters, restart the device, and view detailed diagnostic reports.

[0028] The local diagnostic engine 10 has a built-in rule base and AI model. The rule definition module is used to define business rules, supporting multiple formats such as XML, DRL (Drools Rule Language), and JSON. The rule matching module is used to match input data with rule conditions, typically using the Rete algorithm to improve matching efficiency. The rule execution module is responsible for executing successfully matched rules and triggering corresponding operations. The rule storage module is used to store rule files, supporting local file system or database storage. The visual configuration module provides a graphical interface for users to configure and modify rules online, and is connected to the main control chip 5 to provide computation and storage support. The rule base includes preset fault-phenomenon association rules, such as: access controller offline, its power supply voltage = 0V => power failure, camera image stuttering, network bandwidth saturation, high NVR CPU usage => NVR performance bottleneck. Combined with a simple AI model, a small model trained based on historical data is used to identify more complex associated fault patterns, such as: intermittent disconnection of multiple cameras may be related to abnormal aggregation switch ports or excessive temperature. The cause of the fault is initially analyzed locally, specifically in the following way:

[0029] The collected raw data is sent to the local diagnostic engine.

[0030] The diagnostic engine performs matching analysis based on a preset rule base, for example:

[0031] A camera cannot be pinged => marked as "offline";

[0032] The camera is offline, its power supply voltage reading is normal, and the port status of the connected switch is down => preliminary diagnosis: "network link failure (port or network cable problem)";

[0033] Access control controller communication timeout + its power supply current is 0 => preliminary diagnosis "power failure";

[0034] If the temperature sensor reading in the computer room continuously exceeds the threshold, a "high temperature alarm" will be triggered, and the status of the equipment in that area will be checked accordingly.

[0035] Based on the analysis of multi-parameter correlations using a simple AI model, more accurate hints of potential problems are provided.

[0036] The control panel 2 is equipped with a touch screen and operation buttons such as a reset button, a mute button, a menu button, and an confirmation button, as well as three-color LED status lights.

[0037] The embodiments of this utility model are given for the purpose of illustration and description. Although the embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the utility model. Any changes, modifications, substitutions and variations made by those skilled in the art to the above embodiments within the scope of this utility model should be included within the protection scope of this utility model.
