Parking space guiding and reverse vehicle searching system and method

Abstract

The invention discloses a parking space guiding and reverse vehicle searching system and a method. The parking space guiding and reverse vehicle searching system comprises a parking space and licence plate identifying and positioning device and an inquiry terminal, wherein the parking space and licence plate identifying and positioning device further comprises a center data server, a licence plate identifying computer, a site controller, a guiding screen, a parking space lamp and a camera, wherein the center data server is connected with a vehicle identifying computer by an Ethernet, the licence plate identifying computer is connected with the site controller by the Ethernet, the site controller is connected with the camera, the parking space lamp and the guiding screen, and the center data server is also connected with the inquiry terminal by a wired network or a wireless network. By adopting the technical scheme disclosed by the invention, a parking space guiding system and a reverse vehicle searching system can be combined into a whole; and moreover, the structure is simple, the manufacturing cost is low, and the problems of parking difficulty, vehicle searching difficulty and the like are also solved effectively.

Description

technical field [0001] The invention relates to the technical field of parking guidance, in particular to a parking space guidance and reverse car search system and method. Background technique [0002] With the continuous increase of the number of motor vehicles in our country in recent years, the construction scale of the corresponding parking lot is also increasing. Large-scale parking lots with multiple floors and multiple areas will continue to appear. Some problems of "difficult parking" and "difficult to find a car" ensues. Drivers cannot find a free parking space after entering the parking lot, and drive ineffectively in the parking lot to find an empty parking space, resulting in problems such as congestion of the parking lot passageway and poor air environment. However, when the driver returns to pick up the car, due to the complex internal conditions of the parking lot, it is difficult to quickly find a parking space for his vehicle, resulting in wasted time, imp...

Problems solved by technology

Drivers cannot find a free parking space after entering the parking lot, and drive ineffectively in the parking lot to find an empty parking space, resulting in problems such as congestion of the parking lot passageway and poor air environment

However, when the driver returns to pick up the car, due to the complex internal conditions of the parking lot, it is difficult to quickly find the parking space for his vehicle, resulting in wasted time, impatience, and reduced operating efficiency of the parking lot.

[0003] At present, the solution to the problem of "difficult parking" is mainly to use ultrasonic parking space detection technology, install ultrasonic probes and parking space lights in each parking space, detect and display the empty and full state of the parking space, and use the guide screen to display the number of empty parking spaces in the area, which can solve the problem of difficult parking problem, but it cannot solve the problem of difficulty in finding a car

The solution to the problem of "difficult to find a car" is mainly to locate the vehicle by means of swipe card location, barcode ticket location, license plate recognition location, etc. The disadvantage of swipe card location and barcode ticket location is that the driver is required to go to the positioning terminal next to him after parking the car. It is troublesome to swipe the card or get the ticket. Most drivers will put the card in the car after getting off the car, or forget to swipe it, and the vehicle positioning will not be realized.

[0004] License plate recognition and positioning is to perform license plate recognition at both ends of the passage where the vehicle passes, and continuously update the vehicle position. Due to the high cost, the general area division is large and the positioning is not accurate.

Due to the interference of following cars and pedestrians, the license plate recognition rate cannot be very high, resulting in sliding errors such as vehicle position update errors, which often lead to car finding errors, so the license plate recognition and positioning method is not widely used.

[0005] The combination of the two systems of parking space guidance and reverse car finding can solve the problems of "difficult parking" and "difficult car finding". Well realize the function of freely positioning and navigating
