Vehicle access signal processing method and device

Abstract

The invention discloses a vehicle access signal processing method and device, and the method comprises the steps: receiving a first vehicle access signal transmitted by one of two cameras on a charging pile, and generating or perfecting a charging region parking record through a license plate number in the first vehicle access signal; and receiving a second vehicle in-out signal sent by the otherone of the two cameras, and if the license plate number in the second vehicle in-out signal is the same as the license plate number in the first vehicle in-out signal, determining that the license plate number in the charging area parking record is correct. According to the invention, the double cameras are adopted to identify the vehicle driving into or out of the charging area, so that the defect of insufficient camera identification algorithm is effectively overcome, the situations of license plate number identification errors and non-identification are obviously reduced, and the situationof license plate number embezzlement can be solved.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to a method and device for processing vehicle entry and exit signals. Background technique [0002] With the increasing sales of electric vehicles and the popularity of commercial charging stations, in order to improve the charging experience of electric vehicle users under the premise that the functions of charging stations are becoming more and more mature, a technical solution for using cameras to identify vehicle license plate numbers is proposed. Due to the shortcomings of the recognition algorithm of the camera, there are many problems in the cooperation between the charging system and the camera. [0003] The first is that the camera does not trigger recognition. When the vehicle enters or exits the charging parking space, due to network or camera reasons, the license plate number cannot be recognized, and the license plate number cannot be uploaded to the charging server. ...

AI Technical Summary

Problems solved by technology

The collection of automatic charging service and parking fee equipment occupancy fee is based on the license plate number. If the license plate number is maliciously stolen by others, it will cause losses to charging users.

[0006] Whether it is wrong recognition or non-recognition, or license plate number theft, it will affect the user's experience and even threaten the account security of charging users.
