To avoid fires and reduce fire losses, we must follow the hidden dangers fire in prevention is better than disaster relief, the responsibility is extremely heavy, the concept design and improvement of automatic fire alarm system, fire nipped in the bud, the maximum reduce the loss of social wealth. This paper design a method that use single chip computer and digital voice chip ISD1420 to realize remote voice alarm, gives out the hardware structure and software of system, Based on the single-chip microcomputer 80C51, and speech chip ISD1420,temperature sensor AD590 and gas sensor TGS202 are used, and the multi-sensors information processing method is adopted . Practice the enunciation, The single-chip microcomputer technique has the extensively applied foreground in system alarm and other automatic control realm. This system can automatically to monitor the points which are acute to temperature. It can also send out alarm, show the points and record the occurring time when a fire has broke out. The system can be installed in all fire units, which is responsible for continuously monitoring the site to start the inspection signal, monitor the site of temperature, concentration, and continuous feedback to the alarm controller, the controller will rec
