Road icing detection and pre-warning system based on infrared spectrum technology and method thereof

Abstract

The invention discloses a road icing detection and pre-warning system based on an infrared spectrum technology and a method thereof. The system comprises an upper computer system, a digitized control module, a light transmission module, a light receiving module and an information publishing module. The light transmission module transmits infrared optical pulses with different wave lengths under the control of the upper computer system and the digitized control module; the light receiving module can detect reflected light of the optical pulses on the interface of an object to be detected, is in butt joint with the digitized control module through an optical transmitter and receiver or a wireless communication method, and transmits the reflected light to the upper computer system through data conversion; then current road surface condition is evaluated, the road surface condition is displayed timely through the information publishing module, and when a road surface has an icing trend, the system sends an icing alarm. According to the road icing detection and pre-warning system based on the infrared spectrum technology and the method thereof, different road surface condition including dryness, water, ice and snow cover can be effectively detected, dynamic pre-warning of the road surface condition is achieved more flexibly and precisely, and traffic accidents caused by belated road surface condition judgment or published information not in place on severe weather conditions are reduced.

Description

technical field [0001] The invention belongs to the field of traffic safety and intelligent traffic, in particular to a road icing detection and early warning system and method based on infrared spectrum technology. Background technique [0002] Every year, major traffic accidents caused by icy road surfaces on expressways frequently appear in the newspapers, bringing huge losses to the national economy. The expressway network is an important strategic resource facility that supports national economic development, serves the lives of the masses, guarantees emergency evacuation, and ensures national security. It has the characteristics of fast speed, dense traffic flow, and closure. Bridges, tunnels, viaducts, hubs and other key road sections on the expressway are easily covered with ice and snow when the temperature is low, resulting in a complex traffic environment and the potential for major traffic accidents, which can easily cause regional traffic congestion and affect s...
