Traditional and perspective systems of maintenance and repair of traction rolling stock

Various systems of maintenance and repair of traction rolling stock have been studied using the example of multiple unit rolling stock, and their comparison has been made. The analysis of existing, historically formed systems of preventive maintenance, and perspective maintenance and repair systems based on technical diagnostics data is carried out.As an example, the COMPACS® system is considered, which is a universal system for complex monitoring of the technical condition of equipment, which has a flexible distributed parallel-serial architecture that provides high speed and accuracy of information processing. The main advantage of COMPACS® is the availability of an automatic expert decision support system. The expert system is designed for automatic diagnostics and prediction of the technical condition of the equipment. The task of the expert system is to assist the personnel in making the necessary informed decisions on the management of the operating mode and the state of the equipment. The system of work is described, as well as the scope and principle of operation of this complex monitoring system.The author comes to the conclusion that it is necessary to create an integrated repair system with a scientifically substantiated regulatory effect on equipment, taking into account the actual technical condition of the units and assemblies of the electric locomotive.
