Abstract

The invention discloses gateway equipment for a train. The gateway equipment for the train comprises an IRDA (Infrared Data Association) signal transceiving chip, an IRDA signal transmission control chip and a MVB (Multifunction Vehicle Bus)-IRDA signal conversion control chip; the IRDA signal transmission control chip is connected with the IRDA signal transceiving chip and the MVB-IRDA signal conversion control chip; the IRDA signal transceiving chip is used for sending received IRDA signals to the IRDA signal transmission control chip and receiving the IRDA signals sent by the IRDA signal transmission control chip; the IRDA signal transmission control chip is used for demodulating the IRDA signals sent by the IRDA signal transceiving chip and modulating the IRDA signals sent by the MVB-IRDA signal conversion control chip; and the MVB-IRDA signal conversion control chip is used for converting the IRDA signals into MVB signals and converting the MVB signals into the IRDA signals. According to the gateway equipment for the train disclosed by the invention, wireless communication between the gateway equipment and an analog quantity I/O module is realized through the IRDA signal transceiving chip; therefore, the technological problem of low communication reliability due to the fact that a connection point goes wrong easily can be solved; and the communication reliability is improved.

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 advantages such as low cost. Among them, the Multifunction Vehicle Bus (Multifunction Vehicle Bus, referred to as MBV bus) is the most important one. [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 tech...
