Abstract

The invention provides a train operation control method under special external environments. The method comprises the steps that learning is performed according to historical operation data of a trainunder various external environments, and a train operation environment solution space database under various external environments is generated; in the operation process of the train, an ATO system acquires current train operation data through various sensors, the train operation environment solution space database is inquired according to the current train operation data, the special external environment where the train is currently located is determined, train operation data recommended to be used under the current external environment are obtained, and a train operation controller operatesby tracking the recommended speed curve in the train operation data recommended to be used. The method can enable the train to recognize the levels of special external environments online and to learn control online based on historical data and real-time train conditions in rain, snow, frost and other special external environment conditions so that the train can operate more safely and efficiently in special external environments.

Description

technical field [0001] The invention relates to the technical field of train operation control, in particular to a train operation control method under a special external environment. Background technique [0002] Rain, snow, frost and other special weather will affect the adhesion coefficient, cause the train to idling and slip, affect the control effect of the automatic train operation (Automatic Train Operation, ATO) system, and then affect the parking accuracy and operating efficiency, and even endanger the safety of the train. Especially in high-speed railways, the trains run at high speeds, the distance between stations is large, and the running time between stations is long. The impact of changes in the operating environment on the ATO system will gradually accumulate, which will seriously affect the punctuality and parking accuracy of trains, making it difficult to guarantee the safety of trains. Operational efficiency and operational safety. Research on train opera...
