Problems solved by technology
However, due to the high operating speed, long operating mileage and complex operating environment of EMUs, the existing fixed process flow can no longer meet the needs of various advanced repair bases
At the same time, in the existing commissioning and maintenance process, it is impossible to reasonably screen out unnecessary items, resulting in a waste of maintenance resources

The invention discloses a data management-based priority optimization method for high-level maintenance and commissioning of EMUs, which includes sequentially establishing a maintenance priority model, a failure probability model, a vehicle integrity rate model, a total maintenance cost model, a total maintenance time model and finally establishing Based on the maintenance model, data optimization is performed based on the maintenance model combined with the operation data of the EMUs that need to be overhauled, and finally an optimized suggested maintenance plan is obtained. The technical solution of the invention can improve the operation efficiency of EMU commissioning and maintenance, has good applicability, and reasonably allocates maintenance time, maintenance cost and maintenance effect.
Description
technical field [0001] The invention relates to the field of EMU maintenance, in particular to a data management-based priority optimization method for high-level maintenance and debugging of EMUs. Background technique [0002] At present, with the continuous construction and development of my country's high-speed rail, the number of EMUs continues to increase, and the pressure on EMU maintenance is increasing. The maintenance of EMUs is divided into two types: operational repairs and advanced repairs. Advanced repairs are used to restore the basic performance of EMUs. The commissioning operation runs through the whole process of advanced maintenance, and is an important means to discover and eliminate performance problems of EMUs. [0003] At present, the EMU debugging operation process is mainly based on the maintenance process provided by the original factory. However, due to the high operating speed, long operating mileage, and complex operating environment of EMUs, th...
