摘　　要： 叙述了RS485总线通信控制原理和方法,设计了一套基于RS485总线通信系统,并实现了上位机监控系统与智能仪表之间的实时通信。试验结果表明:该系统性能稳定、传输距离远、通信速度较快、抗电磁干扰能力强,在智能型电气火灾监控报警系统应用中取得了良好的效果。 This paper described the corresponding principle and method of the RS485 bus, and designed a communications system based on the RS485 bus. The real-time communication between the monitoring system and the instrument was realized. The testing result indicates this system, which has some characteristics such as stable performance, far transmitting distance, quick correspondence speed, and anti-electromagnetic interference ability, takes good effect on the Intelligent electrical fire alarm system.
