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

Abstract

A train data transmission method and a computer-readable medium for the initial operation of an adaptive stranded train bus. The method includes: a. Forming arrays A and B in the WTB node, array A is the data received on the WTB, and array B is the processed data; b. Judging whether the adaptive WTB initial operation occurs, and if it has occurred, execute c; if not Execute e if it occurs; c. Determine whether the number of WTB nodes has not changed, and execute d if there is no change; execute e if there is a change; d: if there are two or more elements in the array A that correspond to the same vehicle feature identifier Then execute f; otherwise execute e; e: use the data flow of the elements in array B to perform train communication control; f: only take one of the elements with the same vehicle feature identifier to update the corresponding element in array B, which does not exist in array A If the data of an element in array B exists in array B, the data of this element in array B remains unchanged. Otherwise, the elements in array B are updated according to the contents of elements in 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
