摘   要
本文详细阐述了七层交流变频电梯自动运行程序的设计过程，内容包括电梯电力拖动方式的选择，电气控制方式的选择，以及程序的软硬件设计和说明。经过全面的比较和论证，本设计的电梯的主驱动系统采用性能优越的VVVF(变压变频调速)方式，门驱动系统采用结构简单的直流伺服调压方式，电气控制部分采用控制灵活方便、运行稳定可靠的可编程序控制器（PLC）进行自动控制。系统的硬件部分是由PLC、变频器、各种电气线路及安全保护装置组成；系统的软件部分是由方向控制、开关门、加减速、电气安全保护以及检修状态这五个主要环节组成，设计的电梯能够满足运行要求，即能符合顺向截车，最远端反向截车以及轿内优先等基本控制原则，具有较高的实用性、安全性和可靠性。

Abstract
This thesis particularly expatiate the design process of the seven-lays elevator automatic circulation. the contents includes the choice of the electric drag mode, the electric controls mode and the soft- hardware of the design procedure with explains. With the all-around Comparison and demonstration, the main drive system adopt ascendant VVVF (Variable Voltage Variable Frequency) mode, the door adopt DC servo adjust voltage mode, electric control system use PLC (Programmable Logic Controller) control mode, which has the characteristic of convenience and credit function. The hardware part of the system is composed of PLC, transducer, every kind of electricity circuit and safe protections equip. The software part of the system is composed of  direction confirmation  automatically switch door, acceleration and deceleration, electric security safeguard as well as examine and repair, which provide elevator with practicability, security and reliability. The elevator of the design can satisfy the movement requests.
