多功能车辆总线设备与控制器局域网络之间的网关设备
摘要：
本发明涉及一种多功能车辆总线设备与控制器局域网络之间的网关设备，包括：总线背板、控制芯片和FPGA芯片；控制芯片分别与总线背板和FPGA芯片电连接；总线背板与FPGA芯片电连接；总线背板分别与控制器局域网络中的集中控制器和MVB设备电连接；控制芯片从总线背板接收集中控制器发送的CAN数据信号或者RS232数据信号，将CAN数据信号或者RS232数据信号发送给FPGA芯片；FPGA芯片对CAN数据信号或者RS232数据信号进行协议转换，得到MVB数据信号，将MVB数据信号通过总线背板发送给MVB设备，从而使得集中控制器能够与车辆进行通信连接，使得集中控制器能够对车辆的运行进行控制。
摘要（英）：

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.
