Parking lot vehicle searching system and method

Abstract

The invention discloses a parking lot vehicle searching system and method. The system comprises a server, a vehicle-mounted terminal and a mobile terminal. The vehicle-mounted terminal can perform near field communication with the mobile terminal, and can record vehicle tracks by acquiring data such as the travelling distance and the steering angle of a vehicle; the mobile terminal can communicatewith the server, can store the vehicle track data recorded by the vehicle-mounted terminal, and can transmit the track data to the server; the mobile terminal is used for acquiring an entrance of theparking lot and transmitting entrance data to the server; the server is used for storing parking lot map data and can communicate with the mobile terminal; the server can judge whether the vehicle enters the target parking lot or not according to the GPS positioning signal of the mobile terminal; the server is also used for comparing the map data stored in the server according to the vehicle track data when receiving the vehicle track data sent by the mobile terminal, so as to obtain an accurate parking point of the vehicle; and the server is also used for comparing the entrance data acquiredby the mobile terminal with a stored map to generate a vehicle searching route map. The vehicle searching reliability can be improved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a system and method for finding a car in a parking lot. Background technique [0002] In recent years, my country's economy and society have continued to develop at a high speed, people's living standards have gradually improved, and cars have gradually entered thousands of households. Since there are more and more cars, the scale of the parking lot is also increasing. As a result, how to quickly find your own vehicle among the many vehicles in the parking lot has become a more troublesome thing for car owners. Moreover, the parking lot has its own characteristics: the reference objects are the same, the mobility of the car is high, and it is difficult to distinguish the direction. In this context, the car-finding technology in the parking lot also emerged as the times require. [0003] The method commonly used in the prior art is to rely on GPS positioning signa...

AI Technical Summary

Problems solved by technology

However, for parking lots, especially underground parking lots, due to their location, the GPS positioning signal is often abnormal, and the network connection is also particularly unstable, resulting in inaccurate positioning or the inability to obtain the positioning position, and data interaction is very difficult, so the existing technology adopts The method is difficult to obtain the real-time position of the vehicle, and the reliability is poor
