A road vehicle detection device and detection method

Abstract

The invention discloses a road vehicle detection device, which includes an ETC module, an infrared directing module, a ground sensing coil and a processing module; the infrared directing module is used to determine whether there is an obstruction in a preset area. , sending a occlusion signal to the processing module; the ground induction coil is used to determine whether there is a metal product greater than the first preset quality in the preset area, and when it is determined that there is a metal product greater than the first preset quality, send The processing module sends a metal signal; the processing module is used to determine the vehicle to be detected in the preset area when receiving the occlusion signal and the metal signal, and activate the ETC module; the ETC module uses To identify the vehicle information of the vehicle to be detected and to charge. This application eliminates the interference of non-metallic obstacles and small metal products, greatly improving the accuracy and efficiency of vehicle judgment. The present application also provides a road vehicle detection method with the above beneficial effects.

Description

technical field [0001] The invention relates to the field of vehicle detection, in particular to a road vehicle detection device and detection method. Background technique [0002] At present, the national expressway ETC lanes have been covered. While the rapid passage of vehicles facilitates the passage of vehicles and the convenience of people's travel, it also greatly improves energy saving, emission reduction and environmental protection. The requirements for the accurate, fast, efficient, and intelligent traffic of ETC lanes are even higher, and there are high requirements for the speed and accuracy of ETC lane facilities and systems on expressways. It is relatively complicated, and the performance and characteristics of some equipment itself limit the efficient and intelligent operation of the ETC lane system. [0003] The existing ETC lane can only sense an object entering the detection area, but cannot identify whether the object is a vehicle or other objects to tri...

Problems solved by technology

[0004] The purpose of the present invention is to provide a road vehicle detection device and detection method, which is used to solve the problem that the detection device of the ETC lane in the prior art cannot normally identify the ETC module due to non-vehicle obstacles entering the lane, and then generate error messages, so that the lane cannot be normal. work problem
