Abstract

The invention discloses a locomotive semi-physical simulation device, system and method. The device comprises a real-time simulation unit, a computer and an electrical signal conversion unit. The computer converts a control instruction for simulating an upper-layer network control system into a bus communication protocol, and then sends the bus communication protocol to a communication conversion unit of the electrical signal conversion unit. The communication conversion unit sends the control instruction to an external physical controller, the physical controller outputs a control signal to a controlled object model according to the control instruction, the control signal is sent to a real-time simulation unit via the electrical signal conversion unit, the real-time simulation unit calculates a output result of a state signal of the controlled object model according to the control signal, the output result is sent to the physical controller via the electrical signal conversion unit, and the physical controller sends the state signal of the controlled object model back to the computer via the communication conversion unit. The technical problems that simulation integrity and precision of an existing system are not high, function verification cannot be accurately performed, the modification period is long, and efficiency and performability are low are solved.

Description

technical field [0001] The present invention relates to electrical system simulation technology, in particular to a semi-physical simulation device, system and method applied to locomotives, especially locomotive traction systems. The present invention can also be applied to semi-physical simulations of other similar electrical systems. Background technique [0002] As an important branch of electronic technology, power electronics technology can realize the transformation and control of electric energy, and has been widely used in various fields of national economy such as industry, transportation, and national defense.
