Abstract

The invention discloses a communication device for a rail transportation vehicle and a method. The device comprises a wire-to-board (WTB) card, a DEVICENET card and a central processing unit (CPU) card; the WTB card is used for receiving the WTB communication data sent by external WTB device and sending the WTB communication data to the CPU card, and receiving the WTB processing data sent by the CPU card and sending the WTB processing data to the external WTB device; the DEVICENET card is used for receiving the DEVICENET communication data sent by external DEVICENET device and sending the DEVICENET communication data to the CPU card, and receiving the DEVICENET processing data sent by the CPU card and sending the DEVICENET processing data to the external DEVICENET device; and the CPU card is used for identifying the type of the received data, and correspondingly transforms the data. According to the communication device and the method for the rail transportation vehicle, the communication between the WTB device and the DEVICENET can be realized.

Description

technical field [0001] The invention relates to rail transit vehicle communication technology, in particular to a communication device and method for rail transit vehicles. Background technique [0002] In recent years, with the rapid development of the railway industry, fieldbus has become more and more widely used due to its advantages of high reliability, low cost and low failure rate. [0003] In the prior art, rail transit vehicles usually use two buses for communication, one of which is based on a wire train bus (WTB) for communication, and the other is based on a device network (DEVICENET). [0004] However, each rail transit vehicle only uses one of the communication methods. In this way, in some cases, the same rail transit vehicle may use more than one communication method, sometimes it uses WTB-based communication, and sometimes it uses DEVICENET-based communication. Like this, just need to constantly change the required equipment of communication to this rail t...
