The Development And Research Of Compactpci-bus Daq Card's Driver In Vxworks

With the development of Process Control Technology, the real-time control system is widely utilized in various fields of automation controlling. In the true senses of 'real-time control system', not only does it require the high accuracy and logics of program calculation results, also requires timeliness of calculation result caused. Thus, in order to realize both of functions by real-time control system, computers do need a powerful and mature embedded operation system as a supporting element. So far as it is concerned, currently, Vx Works is the real-time operation system in business sector which majority software engineers give more preferences. Vx Works has already broadly been applied in the area of National Defense, Aeronautics and Astronautics, Communications, Consumed Electronics, Industrial Control and Automobile Electronics etc. It mainly attributes to its two characters of high timeliness and easy R&D. Furthermore, with the rapid pace of automation industry developing, a higher requirement based on computer system platform has been pointed out, which may as well be demonstrated in 3 aspects namely lower cost, strong stability and simple maintenance. Now, Compact PCI computer launched by PICMG organization has highly adopted the new requirement of industrial demand.The research project I was involved, based on the real-time operation system of plasma crystal etching instrument, analyze the reasons why choosing Vx Works as its real-time operation system, why choosing a Compact PCI computer; and how to develop cPCI-9112 core data acquire module under the Vx Works driving program. In this thesis, I will introduce as following:·The current situation of plasma crystal etching instrument;·The reason why to select Vx Works and Compact PCI;·The thorough analysis of the characters and advantages of Vx Works and Compact PCI;·The structure of cPCI-9112 and its primary controlling chip AMCC-S5935 register;·The method of developing PCI equipment under Vx Works;·How to develop driving program for cPCI-9112 under Vx Works;...
