[0002] Tunnels are engineering structures buried in the ground. They are a form of human use of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mining tunnels, etc. At present, in order to ensure the safe use of tunnels, tunnels are monitored by detection devices. After the detection is completed, the data is transmitted to the early warning device to warn vehicles passing through the tunnel, reminding the road conditions of the tunnel and ensuring safe driving of vehicles.
