基于CAN总线的三级智能火灾报警系统

Third Class Intelligent Fire Alarm Systems Based on CAN bus

针对大、中型智能小区的火灾防范的要求,利用CAN总线,设计和开发了一种基于CAN总线的三级智能火灾报警系统。系统由用户端自动报警器、区域控制器、中央控制器和主控计算机四个部分组成,采用三级控制的方案,即采用两极CAN总线和一级RS-232总线作为通信网络。通过在虚拟住宅环境下测试,系统通信能力强,实时性好,高可靠性。同时该系统还具有便于联网以及便于扩展等优点。

For large and medium-sized Intelligent Community of fire prevention requirements, third class intelligent fire alarm sys- tems based on CAN bus is designed and developed in this paper. Third class community structure is adapted in this system, namely： two CAN bus and one RS-232 bus. This system is composed by automatic alarm, local controller ,centraller controller and control computer. By testing, it has many advantages, such as better communication ability, real-time ,high reliability, easy to espend , and easy to access to the network.
