Description

Technical Field

[0001] This invention relates to the field of tunnel management technology, specifically a real-time monitoring and feedback system and device for long-term operation and maintenance of tunnels. Background Technology

[0002] Tunnel management aims to reduce the chances and severity of disasters within tunnels through tunnel safety facilities, designated regulations, and management methods. It ensures timely alarms and self-rescue in the event of a catastrophic accident, minimizing losses. Maintenance can be categorized into hardware maintenance and software maintenance based on the hardware and software involved. Hardware maintenance primarily targets the maintenance of hardware equipment inside and outside the tunnel, while software maintenance focuses on the maintenance of software systems that support tunnel operation. Based on the tunnel maintenance environment, maintenance can be divided into tunnel maintenance and management center maintenance. Tunnel maintenance can also be further divided into internal tunnel maintenance and external tunnel maintenance.

[0003] Currently, existing communication equipment testing devices have the following shortcomings: 1. During the operation and maintenance of existing tunnels, the detection equipment is mostly scattered, making it difficult for managers to collect tunnel operation data and hindering efficient management. 2. During the operation and maintenance of existing tunnels, there is a lack of detection for foreign objects on the ground, which makes it impossible for high-speed vehicles to be alerted to road conditions, thereby increasing the accident rate.

[0004] Therefore, those skilled in the art have provided a real-time monitoring and feedback system and device for long-term operation and maintenance of tunnels to solve the problems mentioned in the background art. Summary of the Invention

[0020] Example 1: The top protective plate 3 and the side protective plate 2 are both fixed to the tunnel foundation 1 with screws. The bottom of the first sensor group 7 is connected to the side protective plate 2 with screws, and the top of the first sensor group 7 is embedded in the tunnel foundation 1.

The exhaust gas remote sensing detection system 10 and the vehicle speed detection module 8 are both embedded in the side protective plate 2. The system is a new type of exhaust emission detection method that uses the principle of spectral analysis to measure the exhaust emission factors of motor vehicles, combines license plate recognition technology to perform one-to-one vehicle inspection, and determines the working condition of the motor vehicle by using information such as speed, acceleration and slope, and combines the environmental meteorological information at the time to determine the validity of the exhaust emission information of motor vehicles. The cable tray 9 is welded to the bottom of the top guard plate 3. The cable tray 9 is hollow. The hanger 6 is hollow. The hanger 6 is connected to the cable tray 9 by hook. The top of the equipment frame 5 is welded to the hanger 6. The cable tray 9 is used to provide power to the electrical equipment in the equipment frame 5 at various positions and to transmit data.

[0021] Example 2: The system control circuit board 13 is embedded in the equipment frame 5. The memory 15 is connected to the system control circuit board 13 by wires. The monitoring unit 11 and the second sensor group 7 are fixed on both sides of the bottom of the equipment frame 5.

By taking pictures of the road surface, it can identify whether there is an abnormality on the road surface by recognizing the image.

[0023] A method for using a real-time monitoring and feedback system and device for long-term operation and maintenance of a tunnel: In practical use, a top plate is installed on the top of the tunnel, and side protection plates 2 are installed on the side walls of the tunnel. The top plate and side protection plates 2 are evenly distributed within the tunnel at a set distance, allowing the detection devices on the top plate and side protection plates 2 to evenly detect the operating status of various areas within the tunnel. Specifically, the displacement sensor 23 in the first sensor group 7 is used to detect displacement deformation at the tunnel top, the humidity sensor 24 is used to detect water seepage in the tunnel foundation, the vibration sensor 25 is used to detect the state of the tunnel rock strata to prevent excessive vibration that could cause tunnel collapse, and the pressure sensor 26 is used to detect the pressure of the foundation soil borne by the tunnel top support. If the pressure is too high, the support is maintained promptly. The data from the first sensor group 7 is transmitted to the system control circuit board 13, and then transmitted to the main server by the wireless transceiver 16. The monitoring unit 11 uses a high-speed camera 21 and an infrared camera 22 to perform safety monitoring of vehicles traveling within the tunnel. The monitoring image is displayed on the first screen. The system displays information on screen 4 and the second display screen 14, showing violations to other vehicles and warning them. The vehicle speed detection module 8 constantly monitors vehicle speed, and the exhaust gas remote sensing detects whether vehicle exhaust emissions meet standards. The wind speed sensor 27 and fire sensor 28 in the second sensor group 7 detect the air quality inside the tunnel. The system control circuit board 13 collects and organizes all detection data and transmits it remotely, achieving complete detection of all areas of the tunnel. The tunnel area detection data is uniformly transmitted to the server via cable tray 9 and wireless transceiver 16, enabling unified adjustment and management, which improves the management efficiency of staff. Compared to the scattered distribution of traditional tunnel operation and maintenance equipment, this saves manpower. Furthermore, when vehicles travel at high speed on the tunnel roadbed 18, the road surface scanner 19 continuously captures real-time images of the tunnel road surface using a CCD-coupled optical sensor camera, analyzes whether there are obstacles, collapses, or protrusions on the road surface, and displays the current road surface status through the road surface alarm 20, alerting vehicles and preventing major accidents.
