Problems solved by technology

At present, more foreign gateway devices are used for data conversion, which is not conducive to localization, and at the same time, the corresponding sending and receiving data cannot be visually displayed, and data debugging is inconvenient
[0003] The existing locomotive FIP network technology is mature, but the equipment operation and maintenance costs are high, the localization level is not high, and there is a lack of testing and verification platforms, and there is a lack of development of CAN-based on-board equipment and FIP network communication test platforms

Abstract

The invention discloses a locomotive FIP network test platform. An FIP bus manager is connected to a PCI-FIP network card through a PCI interface. The PCI-FIP network card is connected with a first junction box through a first joint and an FIP trunk cable. FIP slave equipment is connected to a PCI-FIP network card through a PCI interface. The PCI-FIP network card is connected to a second junctionbox through a second joint and an FIP trunk cable. A CAN master controller is connected with a PCI-CAN network card through a PCI interface. The PCI-CAN network card is connected to a FIP-CAN gatewaythrough a CAN line. The FIP-CAN gateway is connected to a third junction box through a third joint and an FIP trunk cable. An FIP protocol analyzer is connected with a PC machine. The FIP protocol analyzer is connected to a fourth junction box through a fourth joint and an FIP trunk cable. Tested equipment is connected to a fifth junction box through a fifth joint and an FIP trunk cable. The firstjunction box and the fifth junction box are provided with terminal resistors. The platform can realize FIP bus communication technology tests and FIP-CAN heterogeneous network equipment interconnection and intercommunication tests.

Description

technical field [0001] The invention relates to the technical field of railway locomotive field bus network control, in particular to the communication technology of FIP bus and CAN bus. Background technique [0002] Although the locomotive FIP bus technology at home and abroad is mature, foreign manufacturers occupy most of the FIP equipment market, making the use of domestic FIP bus very expensive; domestic research and development of vehicle equipment using the CAN bus, and considering that the research on the CAN bus is relatively mature , the cost of CAN bus equipment is much lower than that of FIP equipment. In practical applications, CAN bus equipment can be connected to locomotive FIP bus, so there is a problem of data exchange between FIP and CAN. At present, more and more foreign gateway devices are used for data conversion, which is not conducive to localization, and at the same time, the corresponding sending and receiving data cannot be visually displayed, and d...
