A kind of method that detects the reversing automobile behavior of high speed fork in the road includes following steps:
Step 1, open speed measuring device 1 and car plate recognition device 2, make it be in the Information Monitoring state, registration of vehicle through out-of-date speed, license plate number and time and be stored in the storer 4, the speed of a motor vehicle determination range that microprocessor 3 is set is initialized as 30km/h～120km/h;
Step 2,3 pairs of above-mentioned information of processor judge, and have judged whether that same vehicle secondary in 5 minutes if having then enter step 3, otherwise returns step 1 through the monitoring crossing;
Step 3, processor 3 judge whether the speed difference of passing through for twice surpasses the scope 30km/h～120km/h that sets, if surpass then enter step 4, otherwise return step 1;
Step 4 records the license plate number of this car and is sent to the vehicle management system of traffic control department and returns step 1.
The method that utilization of the present invention is tested the speed, when vehicle process highway fork in the road, vehicle is normally bigger by the velocity contrast of passing through with reversing, if finding in the short time (being set to 5 minutes) that twice on same vehicle differs through out-of-date speed has exceeded the scope 30km/h～120km/h that sets, can be judged to be the reversing behavior.
The present invention realizes testing the speed by the speed measuring device on the highway, identifies to realize twice elapsed time measurement of same vehicle by car plate.By microprocessor the data that collection collects are handled, and then the reversing behavior is judged, records and uploaded.
The detected velocity information of speed measuring device reaches microprocessor, and microprocessor carries out record during less than this velocity constraint after treatment to vehicle.The present invention is simple in structure, and the reversing behavior by testing the speed to judge vehicle is also carried out store recording automatically.
This device comprises speed measuring device, car plate recognition device and processor, speed measuring device is responsible for measuring the travel speed through vehicle, the car plate recognition device is responsible for judging twice elapsed time of vehicle, after processor is responsible for the data that car plate recognition device and speed measuring device collect are handled, according to go forward side by side line item and be uploaded to the vehicle management system of traffic control department of certain rule judgment reversing behavior.
Advantage of the present invention:
The present invention by the method that tests the speed realize to the reversing behavior identification, at present highway speed measuring device and car plate recognition device are arranged, by linking to each other with microprocessor, in conjunction with two kinds of information acquisition equipment that test the speed and car plate is identified, by the speed of a motor vehicle being compared to judge the reversing behavior, automatically detect vehicle in violation of rules and regulations in conjunction with microprocessor, and in violation of rules and regulations the information of vehicle transfers to the vehicle management system of traffic control department, realizes the automatic detection management function to reversing behavior on the highway.This device can detect the reversing behavior on the expressway effectively, and it installs simple, and control is convenient, saves material, reduce cost, and high efficiency, it is convenient to realize, can realize later function expansion by programming.The automatic record of highway fork in the road reversing behavior and the problem of rule-breaking vehicle reversing evidence obtaining have been solved.
