基于CAN总线技术的智能火灾自动报警系统

介绍了以CAN总线技术为基础，以单片机为多机系统构成的通用智能火灾自动报警系统。CAN是一种快速的串行总线，它为传感器和传动机构之间提供了高效、可靠和经济的连接。CAN采用双绞线连接时，可以实现最多40个设备间的高达1Mbit／s的数据传输。本系统采用了先进的CAN总线技术，并利用诸多的智能特性为解决火灾自动报警系统存在的漏报和误报两大难题提供了新的方法和手段，提高了系统的可靠性和 准确性，并为工程设计施工提供了极大的方便。

Intelligent fire alarm system based on technology of CAN fieldbus

Thisp paper proposes an intelligent fire alarm and control system based on CAN fieldbus technology and multi single chip computer communication system. controller area network(CAN) is a fast serial bus that is designed to provide an efficient, reliable and economical link between sensors and actuator. CAN uses a twisted pair cable to communicate at speeds up to 1Mbit/s with up to 40 devices. Miss alarm and error alarm are two difficult problems in fire alarm system. By use of the new technology of CAN fieldbus and single chip computer technology, the system proposed in this paper provides some new intelligent method to solve these problems. The alarm veracity and system reliability are improved by the use of these new methd and technology. This system also provides great convenience to the design of engineering and construction.
