Research And Development On Device Driver Of Measurement & Control System Based On Windows

The system of computer's measure and control is the basis of advanced manufacture technology and it has been attached great importance widely by all over the world and so it develops fastly. Nowadays,the PC has strong function such as abundant resources of software and handware and opening system structure. Therefore , the measure and control's system based on PC is an important developing trend of the system of computer's measure and control.In the paper, firstly, the tache of position's check has been discussed, then the measuring theory and transition of signal for encoder, which is a high precision measurement are described and the interpolator circuitry is also put forward.Secondly , the characters of PCI and USB bus as well as their material interface application are introduced. Besides, for servo control tache , an simple and credible 1C is applied to little power DC servo control system in order to realize a closed-loop position control system.^ ^Finally, the latest WDM device driver's theory in Windows98/2000 operation systems are discussed on the basis of analyzing the system structure of these platforms. A concrete realizing method of WDM about how to manage bottom hardware and real-time control by for PCI and USB bus are given in detail,which resolves the timing gathering data and communication in Win32 environment for the system of computer's measure and control. t?03In a word , some new ideas for the system of computer's measure and control based on PC has been provided and brought into effect.
