Vehicle guiding terminal device for electric automobile charging and switching station

Abstract

The invention relates to a vehicle guiding terminal device for an electric automobile charging and switching station, comprising a central control processing unit, wherein the central control processing unit 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, a power supply module and a storage module. The central control processing unit adopts an ARM9 as an embedded processor; the central control processing unit is respectively connected with the RFID module and the GPS module by virtue of an RS232 interface and is connected with the wireless communication module by virtue of a serial port or a USB (Universal Serial Bus) interface; and the wireless communication module is a GPRS (General Packet Radio Service) or 3G (3rd-generation) mobile communication module. The terminal device provided by the invention realizes rapid and accurate parking of an electric vehicle on a charging position or a switching position by adopting an image identification navigation mode and an RFID identification location mode and provides guarantee for stable operation of an electric automobile charging and switching station.

Description

technical field [0001] The invention relates to a vehicle guidance terminal device, in particular to a vehicle guidance terminal device 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 battery swap station and how...

AI Technical Summary

Problems solved by technology

[0006] 1) The use of electronic signs not only increases the production cost, but also cannot provide instructions for the driving of each vehicle individually, and cannot make the vehicle drive correctly to the specified charging and swapping potential

[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
