Entrance/exit vehicle passing method, device and system

Abstract

The invention provides an entrance / exit vehicle passing method, device and system. The method comprises the following steps: obtaining and recognizing number plate and RFID card information; if the number plate recognition result and RFID card recognition results are obtained within a preset period, judging whether the number plate recognition result is unmatched with all RIFD card recognition results or not, if the result is negative, controlling the gateway to be in an open state, if the result is positive, recording a first abnormal event, saving the image of the number plate, controlling the gateway to be in an open state at the same time; if only the number plate recognition result is obtained within a preset period, judging the vehicle is a temporary vehicle, controlling the gateway to be in an open state; if no number plate recognition result is obtained within a preset period, detecting the vehicle, if a vehicle is detected, recording a second abnormal event, controlling the gateway to be in an open state at the same time, and if no vehicle is detected, controlling the gateway to be in a closed state. The provided method, device and system increase the passing speed of vehicles in the entrance / exit. The flat-rate vehicles and temporary vehicles can pass the same entrance / exit, the resource waste is reduced, and the traffic safety in the entrance / exit is guaranteed.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a method, device and system for passing vehicles at an entrance and exit. Background technique [0002] At present, entrances and exits usually use a combination of RFID (Radio Frequency Identification, radio frequency identification) card and license plate recognition to pass month trucks, and because temporary vehicles do not have RFID cards, temporary vehicles are identified with license plate recognition. [0003] For monthly card vehicles, if the recognized RFID card recognition results match the license plate recognition results, the vehicle will be released. Under normal circumstances, the RFID card information of the previous car will be read first, and then the RFID card information of the next car will be read. However, in actual use, due to differences in vehicles, such as whether the vehicle has windows open, the thickness of the explosion-proof film, etc., affe...

AI Technical Summary

Problems solved by technology

[0005] In view of this, the embodiments of the present invention provide a vehicle passage method, device and system at the entrance and exit to solve the situation in the prior art that the RFID card information of the rear vehicle is read before the front vehicle, resulting in the failure of the front vehicle to pass through the entrance, or After the vehicle in front passes through the entrance of the vehicle, the RFID card information of the vehicle behind is marked as having entered the venue, making it impossible for the vehicle behind to pass through the entrance and exit, resulting in further congestion at the entrance and exit, reducing the communication rate of vehicles at the entrance and exit. At the same time, the entrance and exit Monthly trucks and temporary vehicles will pass in separate lanes, resulting in a certain waste of resources
