摘要
文章介绍了基于CAN总线技术的烟温复合火灾探测器,主要论述了系统的硬件组成、烟温复合探测原理和实现、软件的设计流程。该探测器可以实现分布式火灾报警控制系统,系统中节点负责数据的采集和初步的处理,上位机对采集的数据进行运算,节点和上位机之间采用CAN总线进行通信。该系统在火灾报警的实时性和准确性方面有了较大的提高。
A multi-sensor fire detector for smoke and temperature based on MCU and CAN bus technology is introduced.Hardware components,detection principles and performance,and software design are discussed.The distributed fire alarm control system can be built up by using this detector,in which nodes are responsible for data acquisition and preliminary processing,and host computer for data processing.CAN bus is used for the communication between nodes and host computer.The proposed system has a better real-time property and higher accuracy in fire alarm.
