It uses the present newly technology, to solve the problems that the storage locations of bearings are not accurate and the matching accuracy is not high. When implemented, it uses CQM1H Serial of OMRON PLC to be the control center, combines with the frequency conversion technologies, the IPCS and highly integrates with the HMIS. This paper introduces system structure, function and the major part of the subsystem design and implementation, and talks about the data collection, storage and matching algorithms in detail. Finally, PLC simulator simulates the control part. The practical application shows that the system has high control precision and performance and it will make great importance on improving the management efficiency of train bearing management.
