摘　　要：针对传统的火灾自动报警控制系统中通信部分出现的问题,提出了利用CANBUS现场总线技术来解决RS485串行口通信方式的传输距离短、节点容量问题的方案。CANBUS控制器局域网总线技术具有极强的抗干扰和纠错能力,较好地满足了大中型火灾自动报警控制系统的网络化的要求。在原有的系统中增设CANBUS总线通信口,来解决火灾自动报警控制系统之间的通信问题。实践表明,经过改造后的火灾自动报警控制系统完全满足通信距离和节点容量的要求,大大提高了系统的可靠性、容量的扩展及与其他系统和设备的连接功能。According to the problems of the conventional automatic fire alarm controlling system communications part, this paper proposesd solving the transmission distance and the node capacity of serial port communication by the way of CANBUS field bus technology. CANBUS controller areanetwork-BUS technology possess strong anti-interference and error correction capability to meet the medium-sized fire alarm control system network requirements. By the way of adding CANBUS communication port in old automatic fire alarm controlling system,it solves the communication question among traditional automatic fire alarm controlling systems. Practice shows that the rebuilt automatic fire alarm controlling system fully satisfies the communication distance and node capacity requirements and improves system reliability, capacity expansion and with other systems and equipments connectivity.
