Developed Based On Visual C + + Parallel Six Degree Of Freedom Platform Monitoring And Control System

In this thesis the Parallel 6 DOF Platform Testing and Control System is introduced, which includes hardware and software. The hardware subsystem is based on computer, data acquisition card, and the parallel 6 DOF platform. The software is based on Windows 98 and the develop tool is Visual C++6.0. The real-time problem of high-speed multi-channel data acquisition under multitask operating system is also analyzed in detail, and the solution to this problem is given then. The OOP (Object Oriented Programming), precise timing and real-time response under windows, and multithreads techniques applied in this system are also analyzed in detail.In chapter one, the structure character and development survey in the world of the parallel 6 DOF platform, the recent applied status of OOP and Microsoft Visual C++ are introduced in brief. The goal and content of this research project are also presented.In chapter two, the platform's positional solutions, including direct solution and reverse solution, and the working space are analyzed in detail, which give the theory foundation of the platform's control. Besides, the hardware utilized in this system is also presented.In chapter three, firstly, on the basis of the compare of OOP and SP (Structure Programming), a conclusion is reached that OOP is the future trend of programming. Then, a comprehensive analysis to the design process of the Parallel 6 DOF Platform Testing and Control System, which based on OOP, is givenIn chapter four, firstly, the difficulty of precise timing and real-time response under Windows is analyzed, and then two solutions to the problem are advanced. One of the solutions is to utilize multimedia timer to time and event to respond. The other is to utilize exterior timer to time and vxd to respond. Secondly, the thesis expounds multithreads applied in the system. At last, the real-time property and reliability of the system are analyzed.In chapter five, the interface of the system and part of the testing results are introduced.In chapter six, the conclusion of the thesis is given, and based on the current research, some suggestions for the system's improvement are also given.
