Automatic monitoring system for automobile overspeed

Abstract

The invention discloses an automatic motor vehicle over-speed monitoring system. In terms of the technical proposal, the system comprises a microwave detection module which is used for projecting a detection area on a detected road, detecting vehicles passing the detection area, and sending the obtained detection data; a video snapping module which is used for identifying and snapping vehicle license plates of the vehicles in a video stream detection manner when the microwave detection module detects the vehicles passing the detection area and sending the snapped images; an information processing module which is used for receiving the detection data sent by the microwave detection module and the snapped images sent by the video snapping module, matching the detection data and the images, and then comparing with the set standard speed value to obtain information of the over-speed vehicle. The system has high detection efficiency, high snapping precision and low manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of microwave communication, in particular to an automatic overspeed monitoring system for motor vehicles. Background technique [0002] Speeding of motor vehicles is one of the main causes of traffic accidents. Due to the excessive speed, the driver's reaction time to traffic conditions is relatively shortened, and in the event of an emergency, the braking distance is long and the vehicle is difficult to control, which will lead to "rear-end collision" and damage to the vehicle in the mild case; serious casualties , Bringing huge losses to society and families. According to statistics, about 30% of traffic violations in cities are speeding, and in the statistics of expressway traffic violations, the proportion of speeding cases is even higher. Therefore, effective measures must be taken to seriously control the phenomenon of illegal speeding, so that drivers can strictly follow the road speed limit regulat...

Problems solved by technology

[0003] At present, in the motor vehicle overspeed automatic monitoring system, there are mainly the following methods, one is to use the loop coil sensor as the overspeed measurement method, plus the camera evidence collection system, this method needs to break the road, especially on the highway Broken roads are very inconvenient, and the measurement accuracy is low, making maintenance extremely difficult; the other is to use speed radar level detection as a means of overspeed measurement, coupled with a camera evidence collection system, this method sometimes causes adjacent lanes. The third is to use the "three-in-one" speed radar vertical detection as a means of overspeed measurement, coupled with the camera forensics system, this method has high capture accuracy, but is expensive, especially when it is applied to multiple lanes, the cost is very high, and There is a certain distance between the speed measurement point and the capture point, and the video capture needs to be delayed, and sometimes there will be mistakes or missed shots
