Application of Time-sharing Scheduling Technology in Traction Motor PHM System
In order to improve the operation efficiency of the traction motor effectively with the urban rail transit train,ensure the safe and stable running of the train,reduce the probability of emergencies such as train outage caused by the failure of the traction motor,we develop the prognostics and health management technology by the traction motor based on the Linux operat-ing system.Aiming at the characteristic of analyze data that the amount of data and the overall algorithm computational com-plexity,the time-sharing scheduling technology is designed by the Linux multi-process shared memory of communication,which can ensure the consistency of data and improve the efficiency of data processing.The train traction motor PHM system has been applied in metro Line 2 of a city and the suitable results have been obtained.
