Non-blind area real-time monitoring and alarming system for highway sudden accidents

Abstract

The invention discloses a non-blind area real-time monitoring and alarming system for highway sudden accidents, belongs to the field of photoelectricity, and can solve the problems that the existing whole-course information monitoring of the highway is lack of all-road-section, all-weather and timeliness, is easily restricted by severe environments such as rainy, foggy and snowy days or unclear sight at night and the like. The system comprises a distributed sound wave detection optical cable, a sound wave signal demodulator, a network switch, a work station and a monitoring terminal. Through a sensing optical fiber network composed of a series of reflection nodes distributed at equal intervals, sound wave signals generated when traffic accidents happen are monitored at a high speed in real time without blind areas, the traffic accidents are accurately positioned by analyzing frequency components, and alarm information is sent in time. Real-time on-line monitoring and timely alarm without blind areas along the highway are achieved, linkage is carried out through a local area network and a video and unmanned aerial vehicle inspection system, accurate positions and types of faults are provided, and large-capacity and long-distance distributed sound wave monitoring is achieved.

Description

technical field [0001] The invention belongs to the field of optoelectronic technology, and in particular relates to a real-time monitoring and alarm system without blind spots for expressway sudden accidents. Background technique [0002] Expressway is an important infrastructure for the development of modern economy and society, and an important foundation for building transportation modernization. As the pride of modern transportation, expressway is the representative of speed and efficiency, and has also become one of the important symbols to measure the modernization of national economy. However, the continuous increase in the mileage of expressways and the rapid growth of vehicle ownership have also brought about many problems, such as frequent expressway traffic accidents, high casualties and property losses, and traffic safety issues have become increasingly prominent. Expressways have the characteristics of high speed, strong sealing, and complex types of vehicles....

AI Technical Summary

Problems solved by technology

[0004] The present invention aims at the problems that the existing expressway full-range information monitoring lacks all sections, all-weather and timeliness, is easily restricted by conditions such as rainy, foggy and snowy weather, or unclear sight in the middle of the night, as well as complex systems and high implementation costs, and provides a sudden expressway monitoring system. The real-time monitoring and alarm system without blind spots in accidents can realize the intelligent perception of vehicle impact sound waves when traffic accidents occur through wavelength and phase demodulation, and link with video and drone inspection systems through local area networks to provide accurate location and category of faults. Solve the problems of low efficiency of manual detection and inability to monitor in real time
