Abstract: The present disclosure provides an operation adjustment method for a metro train in a unidirectional jam, including: generating a train operation routing scheme in the jam according to a jam position; setting priorities for turnaround stations; determining an affected train set; predicting, according to the affected train set, arrival times of each affected train at the turnaround stations of the different priorities; determining, according to the time, planned train service to be executed by the affected train after turning around; and acquiring a planned train service canceled during the jam, and allocating, according to the planned train service canceled during the jam, a train resource for train addition or storage. The present disclosure avoid the conventional complicated operation of manually determining the affected train one by one, and reasonably adds the extra passenger train to arrive at the station on the line for passenger carrying.

Abstract: A method for trains to establish a virtual coupling (VC) operation mode, which includes: successively determining whether adjacent preceding and following trains on a same line meet initial conditions and formation conditions of the VC; and performing VC on both trains meeting the initial conditions and formation conditions, and determining the VC of all trains on the line through the above determination method to obtain an overall VC. The method further including controlling operation of a leading train in the overall VC according to driving permission of the VC, and controlling operation of each of remaining following trains based on communication with the corresponding adjacent preceding train in combination with the following train's own driving information. An establishment process of forming a VC operation mode, thereby improving efficiency of train transportation and flexibility of organization and scheduling.

Abstract: The present disclosure provides a deep learning-based stop control method and system for a high-speed train, and relates to the technical field of rail transit management and control. The method includes: obtaining a training data set; establishing a convolutional neural network (CNN); training and optimizing the CNN by using the training data set, to obtain an optimized CNN; obtaining actual running data of a to-be-controlled train; inputting the actual running data into the optimized CNN to obtain a stop position of the to-be-controlled train; determining whether the stop position of the to-be-controlled train is 0; and if the stop position of the to-be-controlled train is 0, outputting a breaking command; or if the stop position of the to-be-controlled train is not 0, performing the step of “obtaining actual running data of a to-be-controlled train”. The present disclosure can ensure accurate stop of a high-speed train without high costs.

Abstract: The disclosure provides an operation adjustment method and system for metro trains under train out of service. The method includes: acquiring basic parameters of a metro system, information of the train out of service and the online normal running trains, determining follow-up train services and current train timetables thereof, adjusting the current timetables according to predicted time to stop service of the train out of service to obtain initial adjusted train timetables, determining canceled planned train services and rolling stocks for executing remaining planned train services, and adjusting the initial adjusted train timetables according to planned train timetables of the cancelled planned train services. The disclosure can automatically adjust the train operation, and reasonably change the train timetables and the rolling stock circulation plan, thereby reducing influences of the train out of service, and improving the degree of automation of the metro system to adapt to refined management.
