The Research Of Double Anti-theft System Of Vehicle Base On RFID

With the society and economics development, people’s income increasing,consumer attitudes are also changing. the car is not a luxury, the number increase in ahigh speed, more and more like the people’s daily household appliances. Therefore,the car security has become a hot topic in recently. The present automobile anti-thefttechnology have been from the beginning of the mechanical anti-theft system developinto network security system based on electronic equipment. at home, because oftechnical support and the cost, most owners will still choose to use the commonmechanical lock and simple electronic automobile anti-theft device.Currently, there are many types of burglar alarm on the market, a number ofcommonly security products have some limitation, such as poor reliability, anti-theftfunction is simple, it hasn’t the monitoring and tracking function. and the majority ofnetwork type anti-theft system set up by through together high frequency CPU andoperating system, the operation is complicated and expensive. automobile dualanti-theft system based on RFID is studied and implemented in this paper, it isdesigned in the lower hardware configuration environment. the use of the RFIDtechnology, the GSM mobile platform and GPS positioning technology, theautomobile anti-theft device not only can guard against theft, it also can alarmautomatically alarm, and it can tracking after the alarm of the stolen.The system integrates the traditional anti-theft technology and RFID technologyand GSM/GPS technology, RFID is the first heavy security, mainly hold on the door,control car door switch and the ignition system of the vehicle for the opening andclosing. the method is user using the reader to identify label information, determinethe legal of user’s label, if so, the door will open, automobile ignition system willopen, if not, the door will not open, the ignition system is closed. you can operate thevehicle only by the RFID module certification. GSM/GPS is the second car anti-theft, it mainly set up a platform of interactive communication by owner, car and the controlcenter, when the car is stolen, it can make use of GSM mobile network told the ownerthat car is stolen immediate, and get the GPS positioning information report thelocation of the stolen car. in order to relevant staff to find the stolen vehicle in time.This paper introduces the system which involved some working principle, forexample, RFID recognition and GPS positioning principle, as well as the GSM twoinformation transmission format and the AT instruction. Also introduces the researchand design of hardware and software system, the design of hardware, mainlyintroduced chip selection, characteristice, frame design and the schematic design ofseveral major modules. in software, introduces the protocol and command of eachmodule, description of each module of the software design flow chart in detail, andhas some of the key code.The system is different with other market network type automobile anti-theftsystem, it is mainly based on high performance hardware platform. it can betransformed by the mature technology, reliable, low cost electronic anti-theft system,this is not only improve the generality of anti-theft system, but also upgrade the costperformance of production.
