| Abstract: | From the perspective of locomotive safe operation, it was analyzed the defects of the existing Locomotive Bearing Fault Diagnosis System, described the working principle and main components of the Locomotive Bearing Fault On-line Monitoring System, detailed the hardware and software design of the System, expatiated on the two major module design of the data collection and data-processing, the System used data fusion technology for multi-sensor data acquisition in real-time processing, transplanted la C/OS-II Real-time Operating System on the basis of the hardware device, and completed the locomotive CAN bus communication, GPRS communication, automotive display, voice alarm, and other functions by the user application software. The System was more than six months after the actual operation, the result showed that the System architecture designs reasonable, and was a strong practicality. |
