The invention discloses a security prewarning system of pavement visibility and ice and snow accumulation for highway tunnel exists and entrances. The system includes a data processing system, a visibility monitoring system and a snow and ice accumulation monitoring system; the data processing system is used for receiving and processing the snow and ice accumulation monitoring data of whole pavements and the visibility monitoring data of the pavements in the tunnel exist and entrance sections, and then publishing prewarning information to drivers through a prewarning publishing system; the visibility monitoring system is used for monitoring the actual conditions of the visibility of the pavements of the highway tunnel exist and entrance transition sections and feeding back the informationto the data processing system; the snow and ice accumulation monitoring system is used for monitoring the actual icing conditions of highways and tunnels and feeding back the information to the data processing system. The security prewarning system of the pavement visibility and the ice and snow accumulation for the highway tunnel exists and entrances can achieve real-time monitoring, timely feedback and timely prewarning about the visibility of the highway tunnel pavements and the actual conditions of the pavements, and ensure the driving safety of the highway tunnel exist and entrance transition sections on snowy and freezing days with low visibility.
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...
