the elevator by the elevator pared with the traditional, in the run with fort, in life 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 with a set of features to control the election. РIn 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 focus 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.РKeywords elevator Fuzzy algorithm PLC control Simulation
