Intelligent Daily Maintenance Management and Data Analysis System mainly serves for train inspection operation, which consists of four modules: train key component status monitoring module, expert diagnosis module, health management module and equipment intelligent management module. The software can realize the comprehensive management of the data of the main line, the incoming line and each detection equipment in the library. Real-time diagnosis and analysis of detection data, Realize automatic detection and early warning of axle box bearing failure, abnormal temperature of key components of running gear, vehicle running quality, wheelset dimensions, wheel roundness, tread defects, wheel internal defects, brake device wear, pantograph carbon slide plate wear, pantograph contact pressure, abnormal visual appearance components of the whole vehicle on the roof, side and bottom, etc. At the same time, based on big data analysis technology, the functions of data comprehensive analysis, trend prediction, fault diagnosis, life prediction of key components, comprehensive state analysis of bogies, and suggestion of the relationship between lines and vehicles are realized. The system reserves intelligent operation and maintenance, OA management system and EAM system management interfaces, which can realize fast data interaction and information sharing.
