说明：  传统的火灾报警系统是以单片机作为系统的中央处理器。中央控制模块的单片机将探测器采集的信号按照某种算法进行处理、判断。这种系统的缺点是很明显的。由于单片机的资源、速度有限，使得单片机的分析、处理算法不能太复杂。
(Conventional fire alarm system as a system based on single-chip CPU. Central control module will Singlechip detector signal acquisition processing according to an algorithm to determine. The shortcomings of such systems is obvious. As the single-chip resources, the speed is limited, making single-chip analysis, processing algorithms can not be too complicated.)
