Parking plot guiding and reverse vehicle tracking method for parking lot

Abstract

The invention provides a parking plot guiding and reverse vehicle tracking method for a parking lot. After a vehicle enters the parking plot and parks in place, a system can store the association of the parking plot and the vehicle; and after a driver returns to the parking lot, the parking plot of the vehicle can be acquired by a vehicle inquiry machine. According to the parking plot guiding and reverse vehicle tracking method disclosed by the invention, a vehicle guiding function and a reverse vehicle tracking function are integrated; and the intelligence and the efficiency of parking management are greatly improved by using a wireless parking plot detection card, a wireless vehicle identification card, a parking plot guiding screen and the vehicle inquiry machine.

Description

technical field [0001] The invention relates to the field of parking lot management, in particular to a parking space guidance and reverse car search method for a parking lot. Background technique [0002] At present, with the development of the economy and the improvement of people's living standards, there are more and more vehicles in the society, especially in densely populated urban areas. Large-scale parking lots have been established in various places, and they are generally underground parking lots or indoor parking lots, and even multi-storey and multi-regional large-scale parking lots have also emerged. Therefore, the problems of "difficult to park" and "difficult to find a car" follow. produce: [0003] 1. The driver cannot find a free parking space after entering the parking lot, but drives 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. The current...

Problems solved by technology

Most of such parking space detection devices are based on infrared detection and ultrasonic detection. In recent years, some are based on geomagnetic detection. For car search, only the parking space detection device based on image recognition can realize reverse car search. However, the parking space detection device based on image recognition needs to install a camera on each parking space, which has the disadvantages of heavy construction, complicated wiring, high power consumption, and high cost. In addition, when the background light intensity is too weak or too strong, the accuracy of image recognition is low

[0004] 2. 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.

However, the biggest disadvantage of GPS to solve vehicle positioning is high cost and complex technology, and indoor or underground parking lots cannot receive GPS positioning signals, so it is impossible to use GPS technology to realize the vehicle search function in underground parking lots
