Train data transmission method for initial operation of self-adaptive stranded wire type train bus and computer readable medium

Abstract

The invention discloses a train data transmission method for initial operation of a self-adaptive stranded wire type train bus and a computer readable medium. The method comprises the steps: step a, forming an array A and an array B in a WTB node, the array A being data received on a WTB, and the array B being processed data; step b, judging whether self-adaptive WTB initial operation occurs or not, and if so, executing the step c; if not, executing the step e; step c, judging whether the number of the nodes of the WTB is not changed or not, and if not, executing step d; if so, executing stepe; step d, if the vehicle feature identifiers corresponding to the two or more elements in the array A are the same, executing step f; if not, executing step e; step e, performing train communicationcontrol by using the data streams of the elements in the array B; and step f, only taking one of the elements with the same vehicle feature identifier to update the corresponding element in the arrayB, and if certain element data which does not exist in the array A exists in the array B, keeping the data of the element in the array B unchanged, and besides, updating the element in the array B according to the content of the element in the array A.

Description

technical field [0001] The invention relates to the network communication control of rail transit trains, in particular to the data communication for the initial operation of the stranded train bus. Background technique [0002] WTB (Wire Train Bus), the full name of the twisted train bus. The WTB bus is mainly used for train-level communication. Its transmission rate is 1Mbps, which can realize the transmission of process data and message data. Its biggest feature is that it has the function of the initial operation of the train (the function of the initial operation of the train is when the configuration of the train vehicle changes. It can automatically address the vehicles and form a new train topology without human participation). The WTB bus is especially suitable for train vehicles that require dynamic marshalling. [0003] The initial operation of WTB refers to the initialization and reconfiguration of the WTB bus. However, during the initial operation of WTB, the ...

Problems solved by technology

[0003] The initial operation of WTB refers to the initialization and reconfiguration of the WTB bus. However, during the initial operation of WTB, the data will be abnormal or cleared for a short time, which will cause some important train control data in transmission to be unable to be maintained. Therefore, WTB The initial operation may affect the control of the train, and in serious cases, it will cause hidden dangers to the safety of the train
