Vehicle guidance system of electric vehicle charging and battery replacement station

Abstract

The invention relates to a vehicle guidance system of an electric vehicle charging and battery replacement station. The system comprises a monitoring center, one or more vehicle-mounted terminals and one or more ground logos; the monitoring center comprises a monitoring server respectively connected with a wireless communication module I, a path planning module, an electronic map module and a license plate reading module; each vehicle-mounted terminal comprises a central control processing unit and is respectively connected with an RFID (Radio Frequency Identification) module, an image acquisition module, a video coding 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 each ground logo comprises an image logo wire and an RFID logo. The system realizes quick and accurate parking of the electric vehicle at a charging position or a battery replacement position based on the navigation mode of the image logo and the location mode of the RFID logo, thereby providing a guarantee to steady operation of the electric vehicle charging and battery replacement station.

Description

technical field [0001] The invention relates to a vehicle guidance system, in particular to a vehicle guidance system for 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 battery swap station and how to accurately pa...

Problems solved by technology

[0007] 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

[0008] 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
