Document Type and Number:
WIPO Patent Application WO/2023/134093
Kind Code:
A1
Abstract:
Disclosed in the present invention is a virtual subway train operation big data generation method based on an interval speed limit and expert experience. Limited parameters of virtual data, such as a traction interval, a speed interval, a station spacing interval and a speed change interval, are obtained by investigating actual data of subway operation and consulting related experts, such that the generated virtual data is in a small range and has high reliability. Then, a five-section operation mode of a subway train is assumed according to dynamic knowledge, so as to generate a virtual speed-distance image of the train. Afterwards, programming implementation and data visualization are performed by using Python, so as to obtain a large amount of required virtual subway train operation data. Conditional screening is performed on a large amount of generated virtual data, so as to obtain some dotted lines required by a researcher. In addition, a selected single curve is tracked in real time, so as to obtain an operation state of the subway train on the single curve every 0.1 second, such that the real-time operation state of the subway train is learned, thereby facilitating the researcher in further researching the subway train.
