基于PLC的船舶机舱监测报警系统模拟装置设计

Design of Monitoring and Alarm System Simulator Based on PLC for Marine Engine Room

采用AC500PLC、CS31总线,信号模拟,延伸报警等,设计了一个船舶机舱监测与报警系统模拟装置。该系统有3层结构,上层为计算机;中间层为AC500PLC;下层为信号模拟采集、呼叫与延伸报警。上层和中间层之间采用TCP/IP总线,中间层和下层之间采用CS31总线。论文设计了系统的各个功能模块,实现了数据采集,主从数据通信,监测报警及与上位机的数据传送。

The AC500 PLC and CS31 bus were used to build the monitoring and alarm system simulator for marine engine room with signal simulation and alarm extension.The system has three-layers,the upper layer is a computer,the middle layer is a AC500 PLC and the lower layer is signal analog and acquisition,engineer calling and alarm extension.TCP/IP bus was used between the upper layer and the middle layer while CS31 bus was used between the middle layer and the lower layer.Each function module of the system is designed to realize data acquisition,data communication,monitoring and alarm and data transmission with the upper computer.
