In addition, a protective cover 502 is provided, which can protect the detection control terminal 1 to prevent rain, dust, etc. from damaging the equipment.

[0030] Working principle: First, the mounting frame 401 is installed and fixed to the footbridge through the mounting hole 405 on the side of the mounting plate 403. Since a vibration-damping pad 406 is provided at the connection between the mounting plate 403 and the footbridge, the vibration-damping pad 406 can be used to absorb and isolate vibrations, thereby protecting the detection control terminal 1 from the influence of bridge vibrations. At the same time, the mounting frame 401, the mounting plate 403, and the support plate 404 form a triangle. Since the triangle has stability, the mounting frame 401 can be made more stable and secure. Then, the detection control terminal 1 can be slid into the mounting frame 401. During the sliding process, the roller 402 is provided, and the roller 402 can make the detection control terminal 1 slide more smoothly. Then, the limit rod 408 is rotated through the rotating seat 407. At this time, the limit rod 408 will limit the detection control terminal 1. Then, the sensor 2 is installed at different lateral key points of the bridge.

[0031] Next, the solar panel 304 is rotated by rotating the ball 303, thereby adjusting the angle of the solar panel 304 so that it can face the sun, thereby maximizing the amount of solar radiation received. At this time, the rotating ball 303 will rotate in the fixing seat 301. When the solar panel 304 is adjusted to a suitable angle, the locking screw 302 is rotated to fix the position of the solar panel 304. A drainage groove 305 is provided on the side of the solar panel 304 to facilitate the natural flow of rainwater and snow, reducing the accumulation of snow and dirt. Finally, the real-time data of the sensor 2 is transmitted to the detection and control terminal 1. The software in the detection and control terminal 1 will automatically analyze the lateral displacement and vibration frequency of the bridge. If abnormal displacement or vibration exceeding the preset threshold is detected, the detection and control terminal 1 will automatically An alarm is issued to notify maintenance personnel so that they can take timely countermeasures. At the same time, the monitoring data can be stored in the detection and control terminal 1 for a long time to facilitate historical data analysis. By accumulating data on the long-term lateral vibration and displacement of the bridge, the service life and potential risks of the bridge can be predicted. Maintenance personnel can use mobile phones or computer terminals to remotely view the vibration displacement data and alarm status of the bridge received in the detection and control terminal 1 in real time, which is convenient for rapid response and decision-making. The detection and control terminal 1 can be protected by the protective cover 502, and the protective cover 502 can be rotated by the rotating shaft 501, and the U-shaped plate 503 is inserted into the corresponding hole on the side of the detection and control terminal 1.
