Reverse vehicle searching positioning system and method

Abstract

The invention relates to a reverse vehicle searching positioning system and method. The system comprises a reference station, a mobile station, a server and an intelligent terminal, wherein a satellite signal is processed by the reference station to acquire a satellite orbit and a clock error correction number, through carrier wave phase smooth pseudo range, a difference correction number and a correction number change rate are generated and transmitted to the server for storage, the satellite signal is processed through the mobile station to generate a first positioning data which is transmitted to the server or is combined with first positioning data for carrying out vehicle positioning, preliminary positioning data is generated, final positioning data is transmitted to the intelligent terminal, the positioning data is pre-stored by the server, the first positioning data or the preliminary positioning data is corrected to generate the final positioning data, and the final positioning data is displayed through the intelligent terminal. The system is advantaged in that positioning of the mobile station can be corrected in real time, high precision positioning of the vehicle can be realized in real time, the positioning signal is transmitted to the intelligent terminal, and a user is facilitated to realize reverse vehicle searching.

Description

technical field [0001] The invention relates to the technical field of navigation, in particular to a system and method for reverse car search and positioning. Background technique [0002] With the development of human beings and the progress of society, people's social activities are increasing, and people's travel is increasingly inseparable from means of transportation, and more and more people have their own cars. Car owners tend to get lost in large parking lots and forget where they parked, so they can't find their vehicles quickly. This just brings very big inconvenience to people's life. [0003] There are several intelligent systems that can realize reverse car search in the current parking lot. Some systems bind the RFID card with the vehicle, install sensors on the parking space, and realize the reverse direction by identifying the parking space information and combining the facilities of the parking lot. Car search; part of the system uses a large number of si...

AI Technical Summary

Problems solved by technology

The disadvantages of these systems are: 1. A lot of equipment has been invested in the parking lot, such as wireless positioning equipment and RFID cards. These equipment need regular maintenance, and some equipment are large in size, high in power consumption, and high in cost. 2. The positioning accuracy of the vehicle is low, and the owner cannot realize the fast reverse search of the car through these methods, which wastes a certain amount of time; 3. It mainly relies on the parking lot equipment to realize the positioning of the vehicle, and cannot realize autonomous Positioning, the system may lose the function of positioning and finding cars in emergencies

[0007] The above three technical solutions all require the parking lot to invest a large number of parking cards and establish its own control system, and also need to invest manpower and material resources for maintenance in the later stage, which causes a certain economic burden on the parking lot
