Abstract

The invention discloses a semi-physical test platform for a train vehicle control network. The platform includes: a train control unit VCU, a human-computer interaction interface HMI, a vehicle network relay device, a vehicle IO module, a driver control device, a virtual control device, and a physical object. Control equipment, semi-physical simulation equipment, simulated scene, train vehicle communication network, train line, physical control equipment and semi-physical simulation equipment signal conversion device, virtual control equipment communication network, power supply and protection device; solve the problem of existing train vehicle The control network hardware-in-the-loop test method has the technical problems of poor flexibility, high cost, and poor versatility of using real objects. It has realized the technical effect of low cost of the test platform, good flexibility and versatility, and various test functions.

Description

technical field [0001] The invention relates to the technical field of train vehicle control network, in particular to a semi-physical test platform of train vehicle control network. Background technique [0002] The on-board control network of the train is the "central nerve" of the whole train, which realizes the unified coordination of the control equipment of the whole vehicle, monitors the working status of each subsystem, and completes the operation monitoring and fault diagnosis functions of each subsystem of the whole vehicle. An important function of the train on-board control network is the realization of the vehicle control logic. If the verification test of this function is required, the physical train control equipment and its corresponding actuators must be available. [0003] However, in the actual development process, it is unrealistic to equip all the mounting equipment of the vehicle network and the corresponding actuators. On the one hand, there are differ...
