LPC2468-based MVB-WTB gateway and working method thereof

摘要

The present invention discloses a LPC2468-based MVB-WTB gateway and associated operating methods in the field of train communications. The disclosed network gateway includes a MVB network card and a WTB network card. The WTB network card includes WTB-ARM and a WTB-FPGA module. The MVB network card includes MVB-ARM and MVB-FPGA module. The WTB-ARM module uses a LPC2468 processor to analyze data in the network layer and the data link layer based on gateway protocol. The WTB-FPGA module allows WTB to exchange data with other networks gateways, as well as between the WTB and MVB. The MVB-ARM module is responsible for executing protocols on the network cards. Via data communications on MVB, the MVB-FPGA module collects the process and message data of the MVB equipment, and exchange communication data between WTB within a network gateway. The present invention can increase speed and enhance reliability for communications between gateways.
