Разработка новых программных компонент для системы управления дизель-поездом

Abstract

Рассмотрены структуры различных систем управления поездами, показаны их достоинства и недостатки. Для усовершенствования системы управления отечественного дизель-поезда ДЭЛ-02 предложена её модификация, которая заключается в добавлении в существующую структуру дополнительных программных компонент. Это позволило повысить точность работы системы управления, оптимизировать процессы перевозки грузов и пассажиров дизель-поездом, а также сократить время боксования и уменьшить износ бандажей колёсных пар.The analysis of the structures of various train control systems was carried out, on the basis of which the control system of the domestic diesel train DEL-02 was perfected. It is noted that during the movement of the diesel train with the uncertainty of the train situation and the change in auxiliary loads, this system does not allow us to obtain the optimal traffic control law. To do this, its modification is accomplished by adding additional software components to the existing structure. In the software component of the identification of parameters of traction induction motors, an algorithm is implemented to determine their electrical parameters during the movement of the train. The software component of the identification of the moment of resistance to movement is intended to refine the mathematical model of the diesel train with the purpose of adjusting the control system to a real road situation, changing during the movement of the train. A feature of the software component of detection and protection against slippage is that it is built using fuzzy logic (the fuzzy controller performs the task of detecting slippage of wheelsets). This approach made it possible to detect both non-synchronous and synchronous slippage of wheelsets. The proposed software components made it possible to improve the accuracy of the diesel train control system, to optimize the process of transporting cargoes and passengers by diesel-train, as well as to reduce the time of slippage and reduce the abrasion of the wheelsets bandages.
