摘　　要：为保证船舶的安全航行,故提高船舶电力系统的安全性和可靠性十分重要。文中设计了一套基于施耐德M340 PLC、XBTG7340触摸屏和工控机的电力系统故障诊断装置。该套故障诊断装置主要由施耐德M340 PLC、电力系统参数测量装置、XBTG7340触摸屏、工控机、NI数据采集仪、以太网等器件所组成,本诊断装置通过施耐德M340PLC、电力参数测量仪PM800、7个与互感器相连的模拟仪表和NI数据采集仪对船舶电力系统的参数进行相应的采集,将采集到的数据信息通过Modbus现场总线、工业以太网进行数据共享,实现对船舶电力系统装置的监视与检测,并将实时数据导入工控机matlab中进行故障程度与故障类别的判断。In order to ensure the safe navigation of ships, and to improve shipboard power system ＂s safety and reliability, this paper presents an industrial computer monitoring device on the basis of PLC, touch screen and M340. The set of fault diagnosis device is mainly composed of PLC, touch screen, industrial control, parameter measurement equipment for electric power system, NI data acquisition instrument and Ethernet device. The monitoring device collects electrical parameters through PLC, PM800, current transformer and NI data acquisition instrument, the information collected is shared by Modbus fieldbus and Ethernet. This device implements monitoring and detection for shipboard power system and puts the real-time data into matlab to judge the type of fault.
