The AC variable frequency technology has been in a new state. It’s application is becoming more and more widely .But the elevator as an important traffic in skyscraper, it also has developed quickly with the improving requirement of the people. It’s dragging technology has developed from DC timing to AC variable frequency timing and it’s logic control-relay control also has been replaced by PLC. The research topic of this design is Design of elevator automatic control system, mainly uses PLC and its software to realize elevator signal control, and its control core is PLC. Research of the main tasks and contents are: familiar with the requirements of main components, the working process of elevator and elevator performance indicators; establish single elevator control scheme of the system, drawing the general block diagram of the control system; the design and selection of the system principle driven elevator Yi; PLC control system design, hardware design and program I/O distribution; debugging and simulation program; the design of three-dimensional model of car system. For the design of the two core issues, o
