Freight train and speed tracking method and system thereof

Abstract

Disclosed are a freight train and the speed tracking method and a system thereof, switching of a simple substance point model or a multi-mass-point model is carried out according to road condition information and real-time positions, accurate control over a single carriage can be achieved by the multi-mass-point model on special road sections such as turning and uphill / downhill sections with gradient changes, and the speed of the freight train can be tracked through the multi-mass-point model. Rapid operation can be realized through a simple substance point model under most conditions of the whole operation line, operation resources are saved, and stable operation at the whole speed is realized; different operation environment information and the simple substance point model or the multi-mass point model correspond to different fuzzy control rules, in the actual operation process, the corresponding fuzzy control rules can be flexibly switched according to the operation environment and the control object, dynamic compensation is achieved, the operation control of the train is made to better meet the actual operation condition. And a better operation control effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of train operation automatic control, in particular to a freight train and its speed tracking method and system. Background technique [0002] Railway transportation has its unique advantages of large capacity, fast speed, low energy consumption, low cost, and all-weather. In recent years, the research on automatic train operation (ATO) of freight trains has attracted much attention. The research methods have changed from traditional control to Advanced Control Evolution. The automatic driving system of freight trains is also an effective way to improve the efficiency of rail transit operations and reduce the labor intensity of drivers. The tracking control of freight train speed and position is an important research content of ATO. By establishing a suitable dynamic model and adopting corresponding control strategies, the freight train can run along the desired target trajectory. [0003] The structure of...
