The Design Of Control System With Touch Screen Based On The Configuration Concept

Control Engineering plays a fundamental role in modern technological systems. The benefits of improved control in industry can be immense. They include improved product quality, reduced energy consumption, minimization of waste material, increased safety levels, and reduction of pollution. Along with the development of information technology, the requirement of friendly human interface and easy operation is highly demanded. To solve such problems, the configuration concept is applied on the software design.The technical principle of the touch screen was introduced based on the control system in this paper, where the COM technology was encouraged to be used for software architecture. And the advantage of adopting the configuration concept, which was analyzed in the paper from definition and construction respects, to realize the software platform was illustrated in this paper. The controlled object modeling was realized on the MFC platform by adopting the COM technology as well as Object Oriented Concept. While in this paper, it also discussed the interface method in COM programming, COM thread model and the MFC support for COM program. As to the communication, Windows Socket was introduced, based on which network program was realized.The simple BIOS, which has serial port communication function and USB data transfer capability, for the controller has been realized. And the Linux kernel was ported to the ARM processor. Through researching the Linux kernel, the paper summarized the general method to program the device driver and completed the touch screen driver in the Linux environment.
