The Analysis & Design Of The Control Operation Platform Soft Of Electric Traction AC Drive Experiment System

The AC drive presents the development aspect of today world traction power. The experiment technology and equipment of AC drive system are the important method of the study, development and speciality teaching of AC traction engine. The paper analyzes the technology character of the AC traction engine and the importance of the AC traction system experiment equipment, then analyzes and designs the soft of control operation platform which is a part of the electric traction and drive control experiment system which is the main equipment of lab.The paper analyzes the function of the control operation platform and compares the realization method and put forward the method of the realizing the control operation platform by soft. The paper carves up the function modules of the control operation platform. To make the soft run with the higher efficiency and steadily, confirms to design the soft of the control operation platform under the operating system of Windows 2000 and using the VC++6.0 programming language.The soft firstly sets up the application frame using the VC++ application guide and adds controls and codes in the frame to realize the soft function. The paper realizes all kinds of functions of the soft of the control operation platform by designing the controls and codes of function modules which includes the driver control instrument dialog module of implementing the function of control instruction input, character parameter setting dialog module and show output window module of the main running state and running parameter of the test platform and others. The soft uses double cushion technology in order to resolve the coruscation phenomena when dynamic parameters are drawn again. The soft realizes the module of wave shape stored and read and the module of the main running parameter stored and read by reading and writing files. The soft realizes the communication module between the control operation platform and the control cell of test platform by using multithreading serial communication. Thepaper introduces detailedly the multithreading serial communication technology because of its importance.The paper realizes the function of the control operation platform through analyzing and designing the soft of control operation platform. Lastly proves the feasibility and rationality of the soft design through simulation running.
