Study On An Numerical Control System Of Laser Power Based On The Platform Of Windows

This thesis is accomplished with the studying of the control system of laser power.With The sharply development of numerical control system and laser technology, the two technology have been combined. Today WINDOWS has been the major OS, it possesses some characteristics of open architecture, easy operating and integrated exploiting environment, so it is essential to exploit the CNC system on basis of WINDOWS, the CNC system based on windows has been a major development direction .This thesis researches the PC-based CNC system under WINDOWS OS. The main object of this system is YAG Pulse Laser Power. A control card has been done to generate the required signal of laser power . The following have been done in this thesis:1. Discuss the development history, current conditions and the trend of laser system and CNC technology.2. Research the real-time character of WINDOWS, discuss and compare the real-time control technology under WINDOWS using DLL and VxD. Besides, discuss the VxD technology deeply.3. Study on the multitask character of CNC under WINDOWS OS, bring forward the way resolving the multitask management of CNC using multi-thread technology.4. Discuss the method using PC BUS technology to produce the control card of laser power.5. Perform an basic CNC system using the control card of laser under Windows98 OS.
