Expressway tunnel abnormal event alarm method and system based on multiple information channels

Abstract

The invention discloses an expressway tunnel abnormal event alarm method and system based on multiple information channels, and the method comprises the steps: collecting a video image signal in an expressway tunnel; processing the video image signal by adopting a background splitting algorithm to obtain information of each vehicle; tracking each piece of vehicle information to calculate corresponding vehicle data information, comparing the vehicle data information with preset vehicle threshold data information to judge whether abnormal event data exist or not, and the vehicle data information comprising existence data information, speed data information and parking data information. Under the condition of judging that abnormal event data exist, the method overcomes the defects that in the prior art, highway tunnel monitoring is single and not comprehensive, accuracy of automatic abnormal event recognition is low, early warning and monitoring cannot be conducted timely and accurately after abnormal events occur, accident processing is not timely, and more serious secondary accidents are caused.

Description

technical field [0001] The invention relates to the technical field of expressway monitoring and alarming, in particular to a method and system for expressway tunnel abnormal event alarming based on multiple information channels. Background technique [0002] Expressway, referred to as expressway, refers to a highway specially designed for cars to travel at high speed. Expressways have different regulations in different countries and regions, in different eras, and in different research and academic fields. According to China's "Technical Standards for Highway Engineering" (JTG B01-2014), expressways are multi-lane highways that are designed for vehicles to travel in separate directions and in separate lanes, and all access and exit are controlled. Mountains encountered on the expressway are handled by opening tunnels. [0003] The monitoring of expressway tunnels in the prior art is not comprehensive enough, and the accuracy of automatic identification of abnormal events ...

AI Technical Summary

Problems solved by technology

[0005] In view of the above-mentioned technical problems, the purpose of the present invention is to overcome the lack of comprehensiveness of the expressway tunnel monitoring in the prior art, and the accuracy of automatic identification of abnormal events is low, so that it cannot be timely and accurately warned and monitored after the occurrence of abnormal events, thereby Accidents are not handled in time, resulting in more serious secondary accidents, so as to provide a way to obtain the internal conditions of expressway tunnels from multiple information channels during use, so as to timely and accurately warn and monitor internal abnormalities The multi-information channel-based expressway tunnel abnormal event alarm method and system to ensure traffic safety, and effectively send out alarm signals to deal with the accident in time and warn the rear vehicles to ensure traffic safety
