Vehicle overload and limit detection method, device and system based on automobile electronic identification

Abstract

The present invention provides a vehicle overload detection method based on automobile electronic identification, comprising: obtaining the radio frequency signal sent by the electronic identification of the vehicle through a plurality of electronic identification reading and writing devices of the vehicle, and analyzing the radio frequency signal to obtain the vehicle size information and the position information of the electronic identification; according to the position information of the electronic identification and the size information of the vehicle, it is judged whether the vehicle enters the weighing area; if the vehicle enters the weighing area, obtain the Video information of the weighing area; according to the position information of the electronic sign and the size information of the vehicle, determine the sensor in contact with the vehicle, and obtain the weight of the vehicle according to the pressure change of the sensor. The invention utilizes the advantages of the electronic license plate technology in license plate recognition rate, license plate matching and position positioning, greatly improves the law enforcement credibility of the off-site law enforcement system, and ensures evidence-based law enforcement.

Description

technical field [0001] The invention relates to the technical field of monitoring of intelligent traffic management, in particular to a method, a device and a system for detecting vehicle overload and overrun based on vehicle electronic identification. Background technique [0002] Vehicle overloading, overrunning and speeding seriously damage highway bridges and culverts, and bring great safety hazards to transportation. At present, the relevant departments adopt the mode of vehicle overload off-site law enforcement to manage the vehicles. Through the vehicle overload off-site law enforcement system, the combination of video and weighing can completely monitor the status of all passing vehicles on roads and bridges. , protection, monitoring required timely and accurate detection data. [0003] However, in the current mode of vehicle overloading off-site law enforcement, the vehicle identification uses the license plate recognition camera to recognize the license plate, but...
