Test platform for train network control system based on CAN (Controller Area Network) bus

Abstract

The invention provides a test platform for a train network control system based on a CAN (Controller Area Network) bus. The test platform comprises the train network control system and a test system connected with the train network control system by the CAN bus; the test system comprises a board card unit and a processing unit, wherein the board card unit is used for simulating a logical relation between nodes in a train CAN, receiving a control instruction sent from the train network control system to a target node in the train CAN through the CAN bus, and simulating operation data when the target node executes the control instruction; and the processing unit is used for judging the operating condition of the train network control system according to the control instruction and the operation data. When the tested train network control system is changed, the logical relation between the nodes in the test system is changed to match the tested train network control system, so that the flexibility of the test platform is improved, the cost is reduced, the construction period of the platform is reduced, and batch test can be realized.

Description

Technical field [0001] The invention relates to the testing field of train systems, in particular to a test platform of a train network control system based on CAN bus. Background technique [0002] The train network control system is one of the key technologies to maintain the stable and high-speed operation of the EMU. It is the nerve center of the EMU and is responsible for completing train operation control, monitoring and diagnosis. The driver completes the control of the train's traction and braking by controlling the train network control system to realize the normal operation and operation of the train. [0003] Before the train network control system is installed on the train, it is often necessary to carry out systematic tests to reduce the problems of the train network control system in actual production. Among them, the various components of the train network control system are connected through the controller area network. (ControllerAreaNetwork, abbreviated as CAN) b...
