数字感温火灾探测系统的研究

The Study on Digital Temperature Fire Detecting System

针对传统的感温火灾探测器是基于简单双态的二进制探测器并且不能够编址的问题,数字温度传感器DS18B20与单片机AT89S51以及上位机构成的感温火灾探测系统,可以实时检测各检测点的温度,判断其温度变化趋势,在火灾发生的初期进行报警,并可准确判断报警的地址,从而提高火灾报警的准确度,为灭火赢得时间。

Because the conventional temperature fire detector is based on the simple binary two-state and can not be addressing, the fire detecting system which is included with digital temperature sensors DS18B20 and MCU AT89S51, as well as a upper computer can detect the real-time temperature and the temperature change trend in the early stages of the fire, and judge the alarming address accurately. The system enhances the fire alarming accuracy and gain time for fire fighting.
