摘要
Abstract
At present,the locomotive automatic driving device has been applied to multiple lines and has achieved certain phased results.Due to factors such as complex application scenarios,strong non-linearity and discreteness of control objects,some problems and challenges have arisen during the operation assessment,including impulsive and surging phenomena during train interval operation,non-compliance with station benchmark parking accuracy requirements,failure to start on steep slopes,and difficulty in evaluating air braking performance.These problems seriously affect the smoothness of operation and driving safety.The article studies the automatic driving control technology for key scenarios.Through in-depth analysis of operating procedures and historical operating data,optimization of train dynamics model parameters,establishment of accurate basic resistance models and air braking models,design of expert knowledge base for smooth operation strategy,intelligent parking control strategy,air braking terminal predictive control method,model and data-driven safety evaluation method,the problems encountered in on-site operation are ultimately solved.By the proposed strategies,it achieves the goal of 100% fully automatic control for the main line operation of 20 000 ton combined trains,providing a technical foundation for the normalized application of locomotive automatic driving.关键词
