Title Based on SCM security device design Abstract Along with the people the great improvement of living standard, people's awareness of protection increases ceaselessly, anti-theft alarm system, fully reflects the value of its application. Anti-theft alarm system design is the family electronic anti-theft system designed to meet the needs of the Hyundai Residence security. This system uses the pyroelectric infrared sensor, its manufacture is simple, low cost, convenient installation, and the anti-theft performance is relatively stable, strong anti-interference ability, high sensitivity, safe and reliable. This kind of security installmenthiding, not easy to be the thief found, at the same time it signals through the SCM system after processing convenience and PC communication, to facilitate unified user management. The design includes two parts of hardware and software design. The hardware part consists of the single-chip control circuit, infrared sensor circuit, the alarm circuit, and LCD12864 display circuit. The processor uses 51 series single chip AT89C52, the software design mainly includes the use of Proteus simulation software can realize the function of alarm and display.
