Application of PLC and touch-screen in the power window control system

In order to meet the requirements of intelligent windows in intelligent buildings, combined with PLC´s high reliability, advanced control technology and touch screen´s friendly interface, easy and flexible configuration programming, we designed the power window control system of intelligent machines based on the PLC and touch screen. Satisfactory results have been obtained through simulation experiments and commissioning. The working principle, hardware construction, software program and function characteristics of the designed intelligent window control system were expounded in detail. The designing of fire associated control functions, skylight communication abnormalities alarm and power down when system running overtime were unique in this paper. The intelligent windows control system has the characteristics of running smoothly, safety, high and reliability, it provides a good solution for smart windows.
