The system consists of user interface, server in remote diagnostic center, and experts client. C/S mode was used between expert and server, B/S mode was used between user and server. The flow chart of equipment remote fault diagnosis help system was framed. Function of signal analysis and fault feature extraction was implemented with virtual instrument technology based on LabVIEW. Function of remote data transmission was implemented by http and ftp. Real-time communication was implemented using commercial communication tools. Oracle database was selected as tools of database management. PHP was selected as implementation language of dynamic interaction. Function of security authentication was implemented by password and token. The system has mature technology base, with rich functions, easy to operate, and with friendly and comprehensive interactive system. It provides a new way of remote fault diagnosis. © 2011 Published by Elsevier Ltd.
