Highway safety distance checking system and detection method thereof

Abstract

The invention discloses a highway safety distance checking system and a detection method thereof. The system comprises wireless magnetoresistive sensors, a radar chronograph and a video image acquisition unit, wherein the wireless magnetoresistive sensors are connected with an industrial control computer through access point equipment, and both the radar chronograph and the video image acquisition unit are connected with the industrial control computer. The detection method includes: after the system is initialized, outputting vehicle detection information to the industrial control computer via the access point equipment and TCP / IP (transmission control protocol / internet protocol) through the wireless magnetoresistive sensors, recording time tn at the moment through the industrial control computer, calculating distance between two adjacent vehicles through speed recorded by the radar chronograph, judging whether the vehicles violate regulations or not according to the distance and the speed, and performing photographing and acquisition on vehicle information if so. The highway safety distance checking system can detect longitudinal vehicle distance of front and back adjacent vehicles in a fixed section of a highway automatically, judges whether the vehicles violate the regulations or not, photographing the vehicles for evidence if so, automatically recognizes plate numbers, and establishes and stores the information of the vehicles violating the regulations.

Description

technical field [0001] The invention relates to the field of expressway vehicle violation detection; in particular, it relates to an expressway safety vehicle distance inspection system and a vehicle inspection method using the system. Background technique [0002] In recent years, rear-end collision accidents caused by the lack of safe distance between vehicles on expressways have become one of the main accident forms of expressway traffic accidents in my country, and frequent multi-vehicle rear-end collisions have caused heavy loss of life and property. [0003] At present, the safe distance between vehicles mainly depends on the driver's visual inspection and experience. Often due to various factors such as disorderly vehicle lane changes and overtaking, it cannot be effectively guaranteed, and there is no feasible technical means for monitoring and management. [0004] The present invention is exactly a kind of technical scheme proposed aiming at the actual demand. Co...
