Abstract

The invention discloses a semi-physical simulation test device for a transmission control unit of an urban rail vehicle. The device comprises a main control computer, a switch, a data interface conversion unit and a signal conversion system, wherein the main control computer is separately connected with a communication conversion unit of the signal conversion system and a physical controller via the switch; the switch is a transfer station of network data, and is used for transmitting the network data among the main control computer, the communication conversion unit of the signal conversion system and the tested physical controller; through the data interface conversion unit, the main control computer directly controls in and out of signals of an analog output unit of the signal conversion system via a data conversion card; and the signal conversion system is connected with the physical controller via an external interface, and is used for conditioning signals and converting network signals. The device has the advantages of simplifying the operation, improving the design efficiency, comprehensively testing and verifying the traction and transmission functions of urban rail vehicles and the like.

Description

technical field [0001] The invention mainly relates to the testing field of transmission control units of urban rail vehicles, in particular to a semi-physical simulation testing device and testing method suitable for transmission control units of urban rail vehicles. Background technique [0002] Transmission control unit is one of the key equipment of rolling stock, known as the "heart" of rolling stock. Its main function is to provide stable traction drive control for urban rail vehicles, and it most directly affects the driving safety and operating efficiency of rolling stock. The transmission control unit is usually composed of single boards such as power supply board, CPU board, digital input and output board, signal conversion board, pulse conditioning board, motor control board, auxiliary processing board, and each single board is inserted into the control unit in a certain way. The backplane performs data exchange between individual boards and sends and receives co...
