The invention relates to a rail vehicle general network controller platform and a control method. The general network controller platform includes a main data processing unit, an Ethernet communication maintenance unit and a general IO acquisition unit, and the main data processing unit includes a main processor and a coprocessor , the main processor and the coprocessor perform data interaction through the shared memory inside the coprocessor; the main processor is connected to the Ethernet communication maintenance unit, and the coprocessor is connected to the general IO acquisition unit; the general IO acquisition unit includes Multiple IO boards with the same hardware interface on the backplane, each IO board contains multiple hardware modules with the same function and the type information of the IO board, and the IO board communicates with the CAN communication node sent by the coprocessor according to its own type information communication. The invention can improve the flexibility and versatility of the network controller platform, and reduce the debugging and maintenance cost of the network controller platform.
Description
technical field [0001] The invention belongs to the technical field of network control and relates to a network control system, in particular to a general network controller platform and control method for rail vehicles. Background technique [0002] The train network control system is the control center of the high-speed train. Every action of the train is dispatched by the train network control system. Therefore, the train network control system is called the "brain of the high-speed rail" and the "nervous system". Based on the complexity of the rail train network control system, in order to control the smooth and intelligent operation of the whole vehicle, the central processing unit needs to obtain the speed information, traction status, braking status, axle temperature, air conditioner and other on-board equipment status of each car, and control There are a large number of digital switches such as pantographs, main circuit breakers, and car doors. Whether it is an EMU o...
