Alarm can sense infrared signal, ultrasonic signal, gravity signal, vibration signal and remote control signals. This paper designs a safe, practical and convenient burglar alarm on the analysis of several mon alarm functions and the actual situation. This paper describes the research and development of the alarm, the advantages and the disadvantages of several different alarms and theirs popularity. The paper also analyzes the detection principles and the physical mechanisms of the popular alarms. And this paper chooses remote control signal, infrared signal and temperature signal as the detection signals. Infrared technology is a very mature technology and human eyes can not see infrared light. It can be used under different weather conditions with good concealment, and strong antiinterference ability. This kind of antitheft alarm system is widely used in homes, offices and other occasions. This design uses infrared signal as a detection signal. Temperature signal is most monly used in daily life and used in most warning systems. Particularly, temperature signal is an essential signal in the fire alarm device. Temperature signal is one of the most intuitive parameters in the specific environment. It can be monitored to judge the spot situation in order to provide the basis for subsequent operations. Remote control technology is highly attention with the development of the intelligent alarm. Remote control technology can control and monitor remote object. Remote control technology can not only control remote alarm equipment, but also monitor the basic situation of the terminal. It is used in alarm system because of the maturity of such technology. This antitheft alarm system selects the remote control signal, the infrared signal and the temperature signal as monitoring signals. Remote control signal is used to remotely control the alarm on and off. The infrared signal and the temperature signal were monitored at the same time after the opening of the alarm. The alarm was triggered when any of these signal reach its threshold.
