Title    A Design of Embedded Home Security Alarm System  

Abstract

Recent years， with the rapid development of economy in town, people's living standards continue to improve, our awareness of security is gradually strengthened. As an important part of smart home, home security gets special attention. In view of the traditional anti-theft doors and windows made of aluminum are easy to be pried, not easy to maintain, with no alarm and so on shortcomings, this paper designs a embedded home security alarm system based on multi-sensor technology and GSM technology. Through the collection and analysis of the intrusion information to obtaining accurate alarm information, it improves the security of the household environment.

The system uses the microprocessor (STC89C52 single chip microcomputer) as the control core, combined with the pyroelectric sensor and photoelectric reflex sensor, to design the system hardware resources. The system uses a modular design. It is pided into the sensor module, the signal processing module and the GSM module. This paper designs the hardware of the sensor module and the single chip microcomputer, completes the production of each circuit module and uses them to build the hardware platform. The program compiles through the software design of each module, and the function of the system has been verified through the experiments.
