Tail license plate filtering method and device for common channel mode, as well as meeting processing method and device for common channel mode

Abstract

The invention discloses a tail license plate filtering method and device for a common channel mode, as well as a meeting processing method and device for the common channel mode and aims to identify and process abnormal conditions in a common channel parking lot. The tail license plate filtering method comprises the following steps of: when a first control machine detects that a vehicle enters a first identification area, acquiring a first license plate identified by the first control machine and first identification time; controlling a barrier gate to open according to the first license plate; when a second control machine detects that the vehicle enters a second identification area, acquiring a second license plate identified by the second control machine and second identification time; comparing the first license plate with the second license plate, and determining an identification time interval according to the first identification time and the second identification time; and when the first license plate is the same as the second license plate and the identification time interval is smaller than a preset interval, determining that the second license plate is the tail license plate of the vehicle and ignoring the second license plate.

Description

technical field [0001] The present application relates to the field of parking lot management, and in particular to a tail plate filtering and meeting vehicle processing method and a related device in a common channel mode. Background technique [0002] The parking lot control system is widely used. In some parking lots, due to environmental conditions, the exit and entrance share the same lane, and two controllers are used to control the same barrier gate. This situation is called the common channel mode. [0003] In the common channel mode, if the tail plate of the exiting vehicle is recognized by the entrance camera, an entry record will be generated and the gate will be opened. The entry record will be detained and occupy the remaining parking spaces in the venue, resulting in inaccurate parking statistics. Because the tail plate of the vehicle on the field triggers the opening of the gate, the barrier will not drop, and the vehicles on the field may directly exit the fi...

Problems solved by technology

[0004] In addition, in the common channel mode, there will be a meeting of cars, that is, when the entrance and exit are coming at the same time, when the exiting vehicle is paying the toll, the entrance recognizes the license plate and opens the gate. Exit vehicles pass first, resulting in fee evasion; or vehicles entering the venue are recognized first, and exit vehicles pass directly first, resulting in fee evasion
