Bridge monitoring system based on wireless sensor network

The bridge monitoring system based on the wireless sensor network comprises a frame, a controller, a signal receiver, a data storage module, a camera and a direction adjusting mechanism, a protection frame is installed at the top end of a placing frame, and the frame is connected with an installation frame through a connecting plate. By arranging the direction adjusting mechanism, the shooting angle of the camera can be adjusted, so that different positions of a bridge can be monitored conveniently, the monitoring range of the device is widened, the camera can be protected by arranging the protection frame, rainwater can be collected and stored in rainy days by arranging the water tank, and the water tank is convenient to use. The camera can be cooled in high-temperature weather, the filter plate can filter impurities doped in rainwater, water in the water tank is evaporated quickly in a high-temperature state, and the filter plate is U-shaped, so that water vapor in the water tank is diffused to the top end
