Abstract: Aiming at the problem of faulty operation in traction substation maintenance, the mechanism of automatic identification error prevention, the selection and development of equipment, communication links and management program based on ASP.Net were researched, and the methods of mal operation prevention were summarized, the traction substation mal operation preventing system based on RFID technology and Web Service technology was proposed. The automatic identification of equipment, voice prompt and process control in this system were realized by adopting RFID tags and PDA at the scene terminal. The interaction of mission data was implemented by adopting Wi Fi and Web Service at the communication link. The management of task information lifecycle was realized by adopting the Web application on the server side. The results indicate that off line operation, automatic identification, voice prompt, automatic alarm, and other functions are realized, and wrong operations are effectively prevented, and the system has been successfully applied to a certain traction substation.
