Locomotive reconnection gateway based on advanced data link control hdlc

Abstract

The invention provides an HDLC (High-level Data Link Control)-based locomotive re-connection gateway. The gateway comprises a first UIC (international union of railways) gateway module and a first HDLC / MVB (multifunctional vehicle bus) converting module, which are electrically connected, wherein the first UIC gateway module receives first WTB (wired train bus) data transmitted by a first locomotive through a WTB; the first WTB data is converted into first MVB data; the first MVB data is transmitted to the first HDLC / MVB converting module; the first HDLC / MVB converting module converts the received first MVB data into first HDLC data and transmits the HDLC data to a second locomotive through an HDLC bus. The problem that a WTB re-connection mechanism locomotive cannot be re-connected to an HDLC re-connection mechanism locomotive in the prior art is effectively solved.

Description

technical field [0001] The invention relates to communication technology, in particular to a locomotive reconnection gateway based on advanced data link control HDLC. Background technique [0002] With the rapid development of the railway industry, as the network communication standard of Chinese railway rolling stock, the Train Communication Network (TCN) has a large application proportion in the industrial field bus network in the field of rail transportation. TCN consists of two busses: the wired train bus (WTB) and the multifunction vehicle bus (MVB). As a train-level network, WTB can flexibly realize the cascading and decomposing of vehicles, and the MVB bus is a vehicle bus that connects the internal equipment of the vehicle and connects each vehicle equipment in a fixed train. [0003] At present, there is a big difference in the reconnection mechanism of railway rolling stock in my country. For example, there is a lack of interconnection between the locomotive based...

Problems solved by technology

[0003] At present, there is a big difference in the reconnection mechanism of railway rolling stock in my country. For example, there is a lack of interconnection between the locomotive based on the High-Level Data Link Control (HDLC) reconnection mechanism and the ordinary WTB reconnection mechanism. conditions of

However, in the prior art, there is no gateway or device to realize the interconnection and intercommunication of these two different reconnection mechanism machine workshops.
