Abstract：With the improvement of people to be resided to the home security requirements, the traditional electronic combination lock is of simple structure, safety performance is poor and the present situation of the low degree of intelligence, according to the actual situation, this paper presents the design of household anti-theft system based on RFID technology.This design will take STC89C52 as the main control chip, with radio frequency card reader system, GSM system, LCD display system and matrix keyboard system realize electronic lock lock and open. The system through the adoption of RFID radio signal to identify specific targets and to read and write the related data, from two aspects of hardware and software design to complete with mobile communications, intelligent home security. Completed a master in the design of MCU and its peripheral liquid crystal display and TC35 interface circuit design, rf, speaking, reading and writing design is given and its working principle and implementation process, and describes in detail the design of short message coding way. At last, through the system test, gives the experiment and effect analysis, shows that the system is low cost, practical function, high safety coefficient, convenient to the masses of users.
