Embodiment Construction

[0035] It should be pointed out that the original data sent by WorldFIP equipment is called WorldFIP communication data, and the conversion of WorldFIP communication data into data that can be recognized by DEVICENET equipment is called DEVICENET processing data. Similarly, the original data sent by DEVICENET equipment is called DEVICENET Communication data, converting DEVICENET communication data into data that can be recognized by WorldFIP equipment is called WorldFIP processing data.

[0036] Embodiment 1 provides a communication device for rail transit vehicles. like figure 1 As shown, the communication device 100 for rail transit vehicles includes: a WorldFIP board 101 , a DEVICENET board 102 and a central processing unit (Central Processing Unit, CPU for short) board 103 .

[0037]Wherein, the WorldFIP board 101 is connected with the CPU board 103, and is used to receive the WorldFIP communication data sent by the external WorldFIP device 110 and send the WorldFIP commu...

Abstract

The invention discloses a communication device and method for rail transit vehicles. The communication device comprises a world factory instrument protocol (WorldFIP) board card, a DEVICENT board card and a central processing unit (CPU) board card. The WorldFIP board card is used for receiving WorldFIP communication data transmitted by an external WorldFIP device and transmitting the WorldFIP communication data to the CPU board card, and used for receiving WorldFIP processing data transmitted by the CPU board card and transmitting the WorldFIP processing data to the external WorldFIP device. The DEVICENT board card is used for receiving DEVICENT communication data transmitted by an external DEVICENT device and transmitting the DEVICENT communication data to the CPU board card, and used for receiving DEVICENT processing data transmitted by the CPU board card and transmitting the DEVICENT processing data to an external DEVICENT device. The CPU board card is used for recognizing the type of the received data and performing corresponding data switching. By means of the communication device and method for rail transit vehicles, communication between the WorldFIP device and the DEVICENET can be achieved.

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 WorldFIP (World Factory Instrument Protocol) for communication, and the other is based on Device Network (DEVICENET) for communication. WordFIP is a fieldbus for automation systems that provides digital connections between field devices and controllers, and between controllers. DEVICENET is a low-cost communication bus that connects devices to a network, eliminating expensive hardwiring costs. [0004] However, each rail transit vehicle only uses one of the communication meth...
