Abstract
The single-chip microcomputer is promising, because it will CPU, memory, and timer input and output interface circuit functions such as counter on a single chip integration, making it the most simple to the hardware circuit, the smallest size of all computers. Especially the instructions, rich with ability, high reliability, make it in the instrument and control has been widely used in the design of microcontroller is to control the security alarm.
Automatic fire alarm system consists of flip-flop thing, fire alarm device and other auxiliary functions of the device. With the rapid development of technology and the SCM, automatic fire alarm system structure, form more flexible. Automatic fire alarm technology tends to intelligent systems that can be combined into any form of automatic fire alarm network forms. So-called intelligent automatic fire alarm system, should be: use a fire detectors will be generated during the smoke signal light, temperature, with analog form, together with the relevant environmental parameters send alarm, together again according to the alarm data and internal storage amount of data, using the criterion to judge fire model, so whether fire system called intelligent automatic fire alarm system.
Because the system to solve the fire alarm system of two problems (misstatement, omission) provides a new method and means, it is automatic fire alarm system in technology. Discusses the design of intelligent fire alarm and fire prevention and perfect for automatic fire alarm system, automatic fire alarm system in detecting fire hazards, reduce shoulder heavy security has an important role.
