Parking lot management system and management method

Abstract

The invention relates to a parking lot management system and management method. The parking lot management system comprises a server, a number of UWB positioning parking cards and at least three UWB positioning base stations. The server comprises a storage unit which is used for storing a virtualized parking lot digital model which models all parking spaces in a parking lot to coordinate the parking spaces. The UWB positioning base stations are connected with the server through cables. The precise coordinates of the UWB positioning base stations are measured in advance and stored in the server as known parameters. The real-time position coordinates of the UWB positioning parking cards are calculated through a three-point positioning method. The server further comprises a comparing calculation unit which is used for comparing parking space coordinates in the parking lot digital model according to the real-time position coordinates of the UWB positioning parking cards to determine whether a car is parked in a parking space.

Description

technical field [0001] The invention relates to a parking lot management system, in particular to a parking lot management system and a management method using UWB technology to locate coordinates. Background technique [0002] The existing simple parking lot management system is to time and count the vehicles entering the parking lot through the parking card at the entrance and exit, to count the total number of vehicles in the parking lot, and to charge and manage the parking time. This system does not pay attention to the status of each parking space inside the parking lot, so it cannot realize the parking induction inside the garage. An intelligent parking management system obtains the real-time status of the parking space by installing a parking space detector on each parking space, thereby realizing parking guidance. The parking space detectors used in this type of system generally include ultrasonic, geomagnetic, and infrared parking space detection equipment. Howev...

AI Technical Summary

Problems solved by technology

However, ultrasonic detectors generally use wired working methods, and wiring and construction are time-consuming, laborious, and expensive.

In order to solve the problem of troublesome construction, a wireless geomagnetic sensor appeared later, which saved the trouble of construction and wiring, but its detection accuracy was reduced

Then there is a composite wireless parking space detector with integrated infrared detection, which improves the detection accuracy, but the cost is also high

However, these parking space detection methods cannot bind the parking space number with the vehicle plate information parked on it, so it is impossible to achieve accurate reverse car search and precise guidance and other parking services. a detector, the system cost also increases

In recent years, a parking space detection technology based on video image processing has also emerged, which recognizes the license plate number through the image and corresponds to the parking space, but the system accuracy is easily affected by ambient light and other surrounding factors.

In the parking management system of the prior art, the parking card is only used as the timing and quantity statistics of vehicles entering and exiting the parking lot, and additional systems are required to realize the parking space information and guidance information
