The invention discloses a highway tunnel entrance and exit road surface visibility and icing and snow safety early warning system, including a data processing system for receiving and processing the entire road area snow icing monitoring data and the road surface visibility monitoring data of the tunnel entrance and exit sections; visibility The monitoring system is used to detect the actual situation of road surface visibility at the transition section of the entrance and exit of the highway tunnel and feeds back information to the data processing system; the snow and icing monitoring system is used to monitor the actual situation of icing on the tunnel road and feeds back information to the data processing system; data processing The system is used to receive and process the snow and icing monitoring data of the entire road area and the road surface visibility detection data of the transition section of the tunnel entrance and exit, and issue early warning information to the driver through the early warning release system. The invention can carry out real-time monitoring, real-time feedback and timely early warning on the road surface visibility and actual road surface conditions of the road tunnel, and ensures the driving safety of the road tunnel entrance and exit transition section in low visibility and ice and snow weather.
Description
technical field [0001] The invention relates to a road surface visibility and icing and snow safety early warning system at the entrance and exit of a highway tunnel. Background technique [0002] With the rapid development of highway traffic in our country, higher requirements are put forward for the convenience, comfort, speed and safety of highways, and the mileage and number of tunnels are increasing year by year. The construction of the tunnel provides convenience for the rapid passage of the highway, but at the same time it brings many safety hazards to the highway traffic. Traffic accidents at the entrance and exit of the tunnel occur frequently due to frosting, icing, snow accumulation and insufficient visibility on the road surface. Vehicles bring risks and affect the safety of people's lives and property. First, due to the difference in ambient temperature inside and outside the tunnel, coupled with the structure of the tunnel itself and the continuous flow of hot...
