Today elevator which is widely used in building. Elevator high-rise buildings as an important means of transport and people's work and life more closely. PLC as a new generation of industrial controllers, its high reliability and advanced technology in the elevator control has been widely used, so that the relay control the lift from the traditional way of development is an important direction of computer control, elevator control and become transformation of the hot spots. The four topics are designed to lift is controlled by programmable controller with touch screen to realize man-machine dialogue.
Firstly, the elevator works, functions and control logic requirements are briefly described, and its working principle is described in detail. Touch screen software with human-computer dialogue to achieve its function.
Finally, the elevator touch screen design, careful calculation to achieve the intended purpose. Test shows that the elevator man-machine interface system has good performance.
