[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1 , 5As shown in Figure 6, this utility model provides a tunnel safety monitoring device. The infrared holographic guardian includes a core functional component, a central control motherboard, a composite interface 12, and a spare interface 9. The core functional component, composite interface 12, and spare interface 9 are all connected to the central control circuit. Under the control of the central control circuit, the core functional component, in conjunction with the composite interface 12 and spare interface 9, acquires the working status of the equipment and the environmental status inside the tunnel in real time. The infrared holographic guardian is installed on the inner wall of the tunnel in a staggered arrangement along the tunnel axis, and the spacing between the staggered infrared holographic guardians changes according to the diameter of the tunnel. The infrared holographic guardian uses multiple sensing methods of the core functional component to comprehensively analyze abnormal situations in the tunnel, realizing timely and effective monitoring of tunnel defects, risks, and equipment. The infrared holographic guardian can be remotely upgraded and remotely configured.

[0025] After prolonged use, railway tunnels may experience lining leakage, cracking, spalling, and settlement, which deteriorates their service performance, reduces structural safety and stability, and seriously threatens train safety. Therefore, this application involves installing infrared holographic guards staggered vertically along the tunnel's axial direction on the inner wall surface. Under the control of a centralized control circuit, the core functional components of the infrared holographic guards, connected to external devices via composite interface 12 and backup interface 9, acquire real-time information on the equipment's operating status and the tunnel's internal environment. By utilizing multiple sensing methods to comprehensively analyze abnormal conditions within the tunnel, timely and effective monitoring of tunnel defects, risks, and equipment is achieved, replacing manual monitoring. This allows for real-time knowledge of the tunnel's structural condition, enabling immediate repair of problematic areas upon detection of anomalies, thereby preventing structural deterioration of the railway tunnel and extending its service life.

[0026] like Figure 6 As shown in the figure, in one specific embodiment of this utility model, the core functional components include a camera module 4, a supplementary light 5, and a multi-source sensor.

The axial distance between two devices on the same side is 10 meters, enabling real-time acquisition of full-coverage images within the tunnel. The response time is 0.5-5 seconds (depending on camera configuration parameters). Simultaneously, the supplementary lights 5 support manual activation, and the brightness of the 16 supplementary lights 5 can be controlled individually. Personnel can arbitrarily control the working status of the supplementary lights 5 according to the actual darkness inside the tunnel, thereby ensuring that the camera modules 4 can acquire clear image data. The camera modules 4 support RTSP and ONVIF access, manual switching between day and night modes, exposure and gain settings, strong light suppression, backlight compensation, video preview, screenshot functions, and simultaneous acquisition of two channels.

[0028] Each camera module 4 has four fill lights 5 evenly arranged around its perimeter. The fill lights 5 are infrared lights, and the divergence angle of the infrared lights is greater than the field of view of the camera module 4, which meets the requirements of full coverage fill light. In addition, they support manual or timed brightness adjustment.

[0029] The infrared holographic guardian integrates multiple sensing sensors, which can upload data to the relay terminal in real time. Temperature sensor 10 can sense tunnel temperature and equipment temperature, illuminance sensor can sense ambient visible light illuminance, and vibration sensor can sense equipment vibration and environmental vibration.

[0032] Camera module 4 uses tempered filter dustproof glass with a dustproof coating on the glass surface, which can effectively reduce dust adhesion when the product is working in tunnels and outdoors, thereby improving the recognition capability of camera module 4. After the infrared holographic guardian is installed vertically and vertically on the inner wall of the tunnel along the tunnel axis, the angle between the fixed bracket 32 ​​and the adapter bracket 31 is adjusted according to the lighting requirements to change the angle of the front of the infrared holographic guardian relative to the tunnel. Then, the bolts are inserted into the arc groove 321 to fix the relative angle of the adapter bracket 31 and the fixed bracket 32, thereby adjusting the angle of the product to adapt to installation in multiple scenarios and at multiple angles. Servo drives camera module 4, supplement light 5, temperature sensor 10 and light sensor 7 to work simultaneously, monitor the environmental data inside the tunnel in real time, and meet the needs of tunnel safety monitoring. This can replace a large number of personnel for regular inspections and can realize real-time monitoring, intelligent analysis and scientific diagnosis of tunnel status and transportation safety.

[0033] During the operation and maintenance phase of the infrared holographic guardian, the maintenance computer performs routine maintenance on the device with the network cable connected to the composite interface 12. When cleaning the dust on the surface of the device, only the dust cleaning component is needed. A combination of a rag, brush, and cleaning agent can be used, along with sealant or tape, to maintain the dust on the device.
