The quality of the lift performance of the impact on peoples lives becoming more and more obvious, it must strive to improve the performance of elevator systems, and ensure the operation of the lift is safe, reliable and energy efficient. The traditional elevator control system uses logic of the relay to control circuit, this kind of controls easily to be crash, maintains inconveniently, the movement life is short, and that occupying a large area of space, it being eliminated gradually. For raising the credibility of the automatic control system and the work efficiency of the equipments, design a set of take PLC as the core controller of the elevator auto control system, using to replace former more complicated of a
