System and method for reverse car search and parking control based on wireless positioning technology

Abstract

The invention relates to a reverse vehicle locating and parking control achieving system based on the wireless positioning technology. The reverse vehicle locating and parking control achieving system comprises a plurality of wireless terminals, a plurality of wireless signal acquiring units and a central positioning control module. Vehicle wireless terminal information sent by each wireless signal acquiring unit is received to form an action track of a vehicle in a park, and the parking position is estimated so as to achieve reverse vehicle locating control. The invention further relates to a reverse vehicle locating and parking control achieving method based on the wireless positioning technology and the system. The reverse vehicle locating and parking control achieving system and method on the basis of the wireless positioning technology combines wireless signal propagation models and a positioning algorithm to promote reverse vehicle locating accuracy, is suitable for informatization organizational management service of various parks, and can ensure maximum reduction of evaluation error under the condition of less system overhead. The structure is simple and practical, treating process is rapid and convenient, working performance is stable and reliable, and application range is wide.

Description

technical field [0001] The present invention relates to the field of traffic management, in particular to the technical field of static traffic organization management, and specifically refers to a system and method for realizing reverse car search and parking control functions in a parking lot based on wireless positioning technology. Background technique [0002] Large-scale parking lots are an important field of static traffic research. Large-scale parking lots are mostly distributed in major traffic source areas (such as airports, railway stations, bus stations, commercial centers, exhibition centers, stadiums, hospitals, etc.), and their road network traffic It is characterized by large traffic volume, mixed nature of traffic flow, long-term / occasional congestion points, and its parking nature is mainly active travel, with obvious arrival, and the duration of parking in the parking lot is short. Large-scale parking lots often have more than 3 parking floors, and each fl...

AI Technical Summary

Problems solved by technology

[0004] (1) On the driving path of the vehicle entering the parking lot, it is necessary to take pictures at multiple locations for multiple image recognition. The accuracy of the system for multiple recognition of different locations of the same license plate is not high. At the same time, the underground parking environment needs supplementary light, which will hinder Driving safety, strong driver aversion;

[0005] (2) Limited by the distribution density of camera terminals, the vehicle positioning area is relatively large, making it difficult to find accurately, and the system construction cost is high;

[0006] (3) The system is highly sensitive to optical components, and the reliability of the system will deteriorate with time

[0008] This kind of wireless sensor positioning technology is not aimed at the parking lot and vehicle use environment. So far, there is no mature and reliable parking lot reverse car positioning technology system that is easy to promote at home and abroad, and there is no information system of any large parking lot in China. Practical and convenient reverse car search service function
