Particularly, in the present embodiment, industrial computer 11 can connect replicating machine 12 by bus, and also can realize with replicating machine 12 by Ethernet mutual, industrial computer 11 is also connected by bus with TCMS equipment 14.The communication interface of TCMS equipment is various, such as, MVB (MultifunctionVehicleBus, MVB) communication interface, controller local area network (ControllerAreaNetwork, CAN) communication interface, ethernet interface, RS485 communication interface etc.In the present embodiment, preferably, industrial computer 11 adopts the form of MVB (MultifunctionVehicleBus, MVB) to be connected with TCMS equipment 14.
Industrial computer 11 is according to the performance parameter of vehicle and communicating protocol parameter, the each subsystem under simulating vehicle running status is carried out by modeling software, wherein, each subsystem comprise on vehicle the vehicle such as driving position system, trailer system, brake system, backup system, accelerator control system, air-conditioning system, signal system, broadcast system, pyrotechnic system on all subsystems.The performance parameter of vehicle and communicating protocol parameter can be obtained by the technology supporting paper of the functional requirement specification of the communication protocol of each subsystem, each subsystem, each subsystem.For trailer system (TractionControlUnit, TCU), performance parameter, as the data transmission characteristics cycle, TCU logical process time delay etc. of TCU.Communicating protocol parameter, as TCU sends to net pressure signal, net stream signal, the motor speed signal etc. of TCMS.In the present embodiment, modeling software can adopt the Matlab/Simulink software with simulation and copying.Can arrange human-computer interaction interface in industrial computer 11, train operator can pass through the running status of the real-time supervision train of this human-computer interaction interface.
Industrial computer 11, after having simulated each subsystem, does not directly generate simulation code, and industrial computer 11 needs to test each subsystem of simulation, generates the test result that each subsystem is corresponding.Whether each subsystem of simulating to detect industrial computer 11 simulates each subsystem under actual vehicle running status truly, and the first expected result prestored in industrial computer 11, includes the expected result of each subsystem in this first expected result prestored.This first expected result is according to the technical protocol signed with main engine plants with by the repeatedly design liaison meeting with subsystems, and the relevant meeting summary, communication protocol, functional requirement specification etc. of signing are formulated.The test result of each subsystem compares with corresponding expected result by industrial computer 11, and when each subsystem testing result is consistent with corresponding expected result, industrial computer 11 generates the simulation code corresponding respectively with each subsystem; And when the test result of each subsystem is inconsistent with corresponding expected result, the performance parameter of adjustment and the inconsistent subsystem of desired structure and communicating protocol parameter, and again according to the performance parameter of the vehicle after adjustment and communicating protocol parameter, this subsystem is tested.Human-computer interaction interface in industrial computer 11 can be provided with the option of parameter adjustment, allows train operator or emulation personnel to adjust performance parameter and the communicating protocol parameter of vehicle by call parameters adjustment option.
In actual mechanical process, the language of modeling software when simulating in the language of the simulation software used in replicating machine 12 and industrial computer 11 is not general, that is, language in modeling software directly can not be sent in replicating machine 12, need industrial computer 11 to be the simulation code that replicating machine 12 can identify by the language compilation in this modeling software.Industrial computer 11, by when generating corresponding simulation code by each subsystem after test, compiles described each simulation code, then each simulation code after compiling is sent to replicating machine 12.When industrial computer 11 generates simulation code, control to carry out automatic error detection and error correction by automatic script, to ensure the accuracy of the simulation code generated.
