Design of the Remote Monitoring and Fault Diagnosis System for Power Electronic Equipment

To meet the requirement of highly real-time,tremendous data transferring and complicated diagnosticcauses of remote momtoring and fault diagnosis with power electronic equipment,a novel idea of distributed systemwith industrial PC(IPC)and PLC controlling field terminal is proposed in this paper.Based on the techniques ofpower electronics,fault diagnosis and network,a remote monitoring and fault diagnosis system with combination ofa three-layer C/S structure and Internet is presented,which achieves with high compatibility between differentequipment.Furthermore,the paper focuses on the discussion about the structure of compatible systems,thecompatibility design of remote monitoring and the realization of field control equipment,such as the data collectionsub-system,the real-time monitoring sub-system,the fault diagnosis sub-system and the data disposal andmanagement sub-system,and the design of the data transferring sub-system and the communication protocol format.
