AI Technical Summary
Technical Problem
When recording vehicle passing information, the existing gate system is easily captured by vehicles that reverse or turn around, resulting in a large number of useless capture information.
Method used
The radar or ground-sensitive coil is used to detect the passing of the vehicle, and the detection signal is transmitted to the upper computer through the microcontroller and the serial network interface module. The capture information of the passing of the vehicle is selected and registered with the capture camera.
Benefits of technology
Effectively screen out the captured information passing by the vehicle, reducing useless records and improving the accuracy and efficiency of records.

Abstract
The present invention belongs to the technical field of parking management, and specifically discloses a method for auxiliary judgment of vehicle passing at a gate. The designed circuit board is used in conjunction with a gate machine to detect whether a vehicle passes through. The method uses an object passing through to block a radar or a ground sensing coil, so that the open end lead of the radar or the ground sensing coil changes its level. The change signal triggers a single-chip microcomputer interrupt to enter an interrupt service program and send a business package. The business package includes a single-chip microcomputer interrupt timing signal. The difference between the two interrupt timing signals before and after is calculated and then compared with a threshold value to determine whether the last interrupt signal is an interference signal or a passing vehicle signal. In addition, a snapshot camera is used to easily filter out snapshot photos of passing vehicles and record passing vehicle information.
