In people's daily life and labor in the production process, the fire offen occurred 。 It will bring great harm, threat to people's personal safety and security.Therefore, timely detection， effective detection，control of fire, extinguishing the fire quickly ，taking effective measures to prevent and reduce the fire hazard is an important means to protect people's property and the safety of national economy .With the information age,based on sensor technology, computer technology and electronic communications technology， fire alarm control system
becomes one of the core of modern fire.
In this design, STC89C51 microcontroller is the core.With the combination of the temperature sensor DS18B20, infrared sensor ST178, ion type smoke detectors and other electronic technology,we design this small-scale fire alarm system,which can give a real-time detection, concurrent sound and light alarm .Once the system is running, SCM will tour detect whether there is abnormal with smoke, temperature, and infrared radiation . When any two or three of them are abnormal, the system will analyze which of the specific exception occurs, and then send the appropriate sound and light alarm, until abnormalities were excluded. This system is suitable for home, office, library, computer room, classrooms and other places.With high reliability and low false alarm rate,it is a simple structure, which is inexpensive and easy to use.

In people's daily life and labor in the production process, when the fire is occurring, it will bring great harm, a threat to people's personal safety and property security. Therefore, timely detection and effective detection and control of fire, extinguish the fire quickly and take effective measures to prevent and reduce the fire hazard is to protect the safety of national economy and an important means of people's property. With the information age to the sensor technology, computer technology and electronic communications technology-based fire alarm control system, as one of the core of modern fire service.
The design STC89C51 microcontroller as the core, the temperature sensor DS18B20, infrared sensor ST178, ion type smoke detectors and other electronic technology, design a real-time detection, concurrent small-scale sound and light alarm fire alarm system. Once the system is running, the microcontroller will tour detection of smoke, temperature, and whether abnormal infrared radiation. When any of them two or three are abnormal, the system will analyze which of the specific exception occurs, and then send the appropriate sound and light alarm, and to exclude abnormalities. This system is suitable for home, office, library, computer room, classrooms and other places, high reliability and low false alarm rate, is a simple structure, easy to use, inexpensive fire detection alarm.
