2、月 10 日AbstractThe design for the status quo of China's elevator industry will be a programmable logic controller (PLC) used for four-storey elevator control logic, through the rational selection and design, not only

3、to improve the reliability of the elevator, maintainability, and flexibility, while extending the of life and shorten the development cycle of the elevator and the elevator control to raise the level of the elevator oper

4、ation to improve the comfort, so that the lift to reach a more satisfactory control effect. In this paper, the design of the elevator by the elevator when compared with the traditional, in the run with good comfort, in l

5、ife can save energy, and achieved good economic and social benefits to achieve the desired purpose. The elevator control system has a mean layer, the Office of calls to the layer selected, manual and automatic functions

6、with a set of features to control the election. In introducing the basic structure of the lift on the basis of the depth analysis of the working principle of the elevator, on the merits and characteristics of PLC, the fo

7、cus of an analysis of the lift hardware design and software design, research and PLC based control system designed to lift the achievement of the program, Finally, the study of this thesis are summarized and prospects. K
