Entrance/exit management system and method of single-channel parking lot

Abstract

The invention discloses an entrance / exit management system and method of a single-channel parking lot and belongs to the technical field of entrance / exit management of parking lots. The system comprises a traffic light intelligent guide system, a license plate automatic identification system and an in-channel vehicle opposite-direction barrier gate opening system, wherein the traffic light intelligent guide system comprises a controller, a traffic light and a vehicle detector; the controller is connected with the vehicle detector and the traffic light; the license plate automatic identification system comprises a server, a license plate identification camera and a barrier gate; the license plate identification camera is connected with the server and the barrier gate; the controller is connected with the license plate identification camera; the in-channel vehicle opposite-direction barrier gate opening system comprises an opposite-direction vehicle detector arranged in a single channel;the opposite-direction vehicle detector is connected with the barrier gate. According to the entrance / exit management system and method disclosed by the invention, the license plate automatic identification system can be combined with the traffic light intelligent guide system, and mutual locking linkage control is realized; the problems that the license plate identification camera still identifies a license plate under a red light state and the barrier gate is opened to let a vehicle pass after the license plate is determined to be effective are solved.

Description

technical field [0001] The invention relates to the technical field of management of entrances and exits of parking lots, in particular to a system and method for managing entrances and exits of single-channel parking lots. Background technique [0002] With the development of license plate recognition technology and the continuous upgrading of parking lot system technology, the application of automatic license plate recognition system has become more and more extensive, and has gradually replaced the previous management mode of IC card swiping or ticket inspection. The single-channel traffic light control system is mainly used in the occasions where the entry and exit share a channel, and the width of the channel can only allow one vehicle to pass, and the vehicles in the channel cannot run parallel or meet each other. [0003] At present, when the license plate recognition system and the single-channel traffic light control system operate independently, they have been appl...

Problems solved by technology

However, when the above two system control technologies are running at the same time: automatic license plate recognition systems are installed at both ends to control barrier gates and single-channel two-way traffic lanes, if the two systems are not controlled by electrical interlocking and software logic. As an organic combination, the system cannot achieve the expected effect, and even become a dangerous hidden danger for entering and exiting the vehicle.

[0004] When the license plate recognition system is independently applied to the occasion of single-channel two-way traffic, the biggest disadvantage is: no matter the red light or the green light state, as long as a vehicle enters the recognition area, the license plate recognition system can automatically open the barrier after recognizing the valid license plate; When the channel traffic light control system is used alone, the biggest disadvantage is: the traffic light system only correctly guides the vehicles at both ends of the single channel to enter the channel under the green light state, and must wait outside the channel under the red light state. However, the direction of the red light should be Waiting vehicles forcibly enter the channel lack of enforcement means of mandatory interception

[0005] Although the traffic light control system is used for guidance in the single-lane two-way traffic, and the underground parking lot cannot meet cars, the gates controlled by the license plate recognition system are installed at both ends of the passage, and it is stipulated that priority can be given to passing in the green light state, and in the red light state. In the state, you must wait in the meeting area outside the passage, but there will always be vehicles in the direction of the red light. When the red light is prohibited, you should wait outside the passage. stop the line and enter the license plate recognition area, the license plate recognition system will also automatically open the gate after recognizing the license plate number in the direction of the red light when the red light is prohibited, and the result will cause vehicles in the direction of the red light to see After your own license plate is effectively recognized and the gate is opened, you cannot consciously abide by the rules of waiting at red lights, and drive into the single lane where you cannot pass other cars without authorization, causing the vehicles that have priority to pass through the green light and are already driving in the lane to face each other in the middle of the lane. Finally, two vehicles traveling in opposite directions converge in the middle of the single lane. Because the vehicles on both sides of the single lane cannot meet and turn around, in order to keep the passage clear, only one side of the vehicle can only go back and forth, which not only seriously affects driving safety, but also Cause channel congestion, but also affect the efficiency of the channel
