Abstract

The invention discloses a train gateway device. A train gateway device, comprising: IRDA signal transceiver chip, IRDA signal transmission control chip and MVB-IRDA signal conversion control chip; IRDA signal transmission control chip is connected with IRDA signal transceiver chip, MVB-IRDA signal conversion control chip; IRDA signal transmission and reception The chip is used to send the received IRDA signal to the IRDA signal transmission control chip and receive the IRDA signal sent by the IRDA signal transmission control chip; the IRDA signal transmission control chip is used to demodulate the IRDA signal sent by the IRDA signal transceiver chip and modulate the MVB ‑IRDA signal conversion control chip sends IRDA signal; MVB‑IRDA signal conversion control chip is used to convert IRDA signal to MVB signal and convert MVB signal to IRDA signal. The train gateway device of the present invention realizes the wireless communication with the analog I / O module through the IRDA signal transceiver chip, solves the technical problem of low communication reliability caused by the easy failure of the connection point, and improves the communication efficiency. reliability.

Description

technical field [0001] The embodiment of the present invention relates to communication technology, in particular to a train gateway device. Background technique [0002] In recent years, with the rapid development of the railway industry, field buses have been widely used in the field of train communication due to their low cost advantages, among which the Multifunction Vehicle Bus (MBV bus) is the most important . [0003] Existing trains usually use MVB-CAN gateways or MVB-RS485 gateways to realize the communication between the train central control unit and the analog I / O modules. [0004] However, since the train gateway and the analog I / O module need to be connected by wires, the connection point between the train gateway and the analog I / O module is prone to failure, and the communication reliability is not high. Contents of the invention [0005] The invention provides a train gateway device to overcome the technical problem of low communication reliability in th...
