The invention relates to a gateway device between a multifunctional vehicle bus device and a controller local network. The gateway device comprises: a bus backboard, a control chip, and an FPGA chip, wherein the control chip is in electrical connection with the bus backboard and the FPGA chip; the bus backboard is in electrical connection with the FPGA chip; the bus backboard is in electrical connection with a centralized controller and an MVB device in the controller local network; the control chip collects CAN data signals or RS232 data signals sent by the centralized controller from the bus backboard, and sends the CAN data signals or the RS232 data signals to the FPGA chip; the FPGA chip carries out protocol conversion on the CAN data signals or the RS232 data signals to obtain MVB data signals, and sends the MVB data signals to the MVB device through the bus backboard, so that the centralized controller is allowed to carry out communication connection with a vehicle, and to control the operation of the vehicle.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to a gateway device between a multifunctional vehicle bus device and a controller local area network. Background technique [0002] At present, with the vigorous development of the international and domestic rail transit industry, in my country's urban light rail, subway and railway vehicles, it is usually controlled by a centralized control computer that collects all signals in the vehicle through the bus and analyzes the collected signals. The operation of vehicles such as light rail, subway and railway. [0003] However, in the prior art, each device inside the vehicle is generally connected through a multifunction vehicle bus (MultifunctionVehicleBus, MVB), and the most promising controller area network (ControllerAreaNetwork, CAN) is usually used between the vehicle and the centralized control computer. Or the asynchronous serial standard interface RS232 to connect, that ...
