The Study And Design Of Electric Bike Anti-Theft System Based On RFID And GSM SMS Technology

With the problem of environmental pollution has become increasingly prominent, further promote the use of green energy transport has become the people’s urgent needs, as an important means of transport for people’s daily short trips, electric bikes have been playing an important role in people’s lives, but the electric Bicycle theft problem also plaguing many users. Therefore, the design of a safe, inexpensive, easy to use electric vehicle anti-theft system becomes very valuable.This paper analyzes the advantages and disadvantages of the current electric bicycle anti-theft mode,and the RFID technology is applied to the electric bicycle anti-theft and start system,while in order to increase the convenience of users, the GSM short message technology also added to the anti-theft system, this has brought a try for the future operation of the data management of electric bicycles. the paper describes in detail the basic RFID system constitution, RFID reader and data coding and communication between electronic tags,and analyzes the methods to set password and writing the electronic tag. At the same time introduces the basic components of the GSM network as well as the basic working principle and the way to send short messages. In the hardware design to test the structure for a variety of RF antenna by HFSS frequency electromagnetic simulation software gives a better antenna design. While the anti-theft system designed RFID reader module, MCU module, battery transformer module, GSM module and serial communication module peripheral circuits and details associated pin connection diagram and schematic. In the paper also studied how to improve the EMC of the hardware PCB design.Based on the production of hardware systems, the use of C language programming throughout the anti-theft system software flow chart drawing software, write performance function to achieve control of the hardware.
