摘要：随着我国经济的高速发展，微电子技术、计算机技术和自动控制技术也得到了迅速发展，交流变频调速技术已经进入一个崭新的时代，其应用越来越广。而电梯作为现代高层建筑的垂直交通工具，与人们的生活紧密相关，随着人们对其要求的提高，电梯得到了快速发展，其拖动技术己经发展到了调频调压调速，其逻辑控制也由PLC代替原来的继电器控制。
 本次设计是以电梯控制技术为背景，针对以前的拖曳电梯的一些缺点，采用现在流行的PLC控制技术、变频调速技术、现场总线技术来实现电梯的各种控制。用西门子S7-300控制电梯的常规控制，并且通过S7-400与工业以太网上的上位机进行通讯，上位机通过软件可以对电梯进行实时远程监控。而电梯的升降、起停的速度由变频器控制，楼层的位置由旋转编码器来检测。

The designed of the elevator system of frequency conversion timing based on siemens PLC

Abstract: With the development of the economy, microelectronic technology, computer technology and the automatic theory are developed rapidly, the AC variable frequency technology has been in a new state. Its 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 .Its dragging technology has developed from DC timing to AC variable frequency timing and its logic control- relay control also has been replaced by PLC.
 On this paper, it was based on by the control technology of the elevator, aim at the some weakness of the haulage elevator of the past, the popular PLC control technology and change the adjust soon total line in technique, the spot technique were adopted to every kind of control that realizes elevator. Siemens S7-300 was adopted to the programmable control in this subsystem, and was communicated through S7-400 with the computer of Industral Ethernet ,  The computer passes the software can proceed to the elevator with the on time long range supervises and control. but the rise and fall、rises to stop speed of the elevator was controlled by the transducer, The place of the floor was examined by revolution coder.
