Vehicle guide system of electric vehicle charging station and guide method

Abstract

The invention relates to a guide method for a vehicle guide system of an electric vehicle charging and replacing station. The guide system comprises a monitor center, one or more vehicle terminals, and one or more ground marks, wherein the monitor center comprises a monitor server; the vehicle terminal comprises a central control processing unit, which is respectively connected with an RFID (radio frequency identification) module, an image acquisition module, a video encoding module, a vehicle data acquisition module, a vehicle control module, a display module, a GPS (global positioning system) module, a wireless communication module (II), a power supply module, and a storage module; and the ground mark comprises an image mark line and an RFID mark. The guide method comprises the following steps: (1) vehicle information reading and processing; (2) path planning, and map information returning; (3) visual navigation; (4) IRID location charging and battery replacing. By adopting image mark navigation and RFID mark location, the method can guide electric vehicle to park at charging position or replacing position rapidly and accurately, thereby providing guarantee for stable operation of the electric vehicle charging and replacing station.

Description

technical field [0001] The invention relates to a vehicle guidance system and a guidance method, in particular to a guidance method for a vehicle guidance system of an electric vehicle charging and swapping station based on RFID technology and visual recognition technology. Background technique [0002] As a new energy delivery tool that can replace traditional power vehicles, the development of electric vehicles has attracted more and more attention from the government and enterprises, and more and more manpower, material and financial resources have been invested in this field, leading the automobile industry to a new era. direction of development. [0003] In the practical application of electric vehicles, for the convenience of use, the main way is to replace the battery. After the electric vehicle enters the charging and replacing station, it needs to drive to the changing potential by itself, and the robot will replace the power battery. Automatic navigation in the ba...

Problems solved by technology

[0006] 2) The problem of precise parking of the charging car in the parking space cannot be realized. Generally, the angle between the vehicle and the battery replacement manipulator is required to be no more than 15° when the battery is replaced, and there are strict requirements on the parking position of the vehicle

[0007] 3) The camera monitoring method used in the station cannot count the real-time status of each vehicle in detail, and cannot realize the real-time positioning and monitoring of vehicles in the station
