摘   要
本文詳細闡述了七層交流變頻電梯自動運行程序的設計過程，內容包括電梯電力拖動方式的選擇，電氣控制方式的選擇，以及程序的軟硬件設計和說明。經過全面的比較和論證，本設計的電梯的主驅動系統采用性能優越的VVVF(變壓變頻調速)方式，門驅動系統采用結構簡單的直流伺服調壓方式，電氣控制部分采用控制靈活方便、運行穩定可靠的可編程序控制器（PLC）進行自動控制。系統的硬件部分是由PLC、變頻器、各種電氣線路及安全保護裝置組成；系統的軟件部分是由方向控制、開關門、加減速、電氣安全保護以及檢修狀態這五個主要環節組成，設計的電梯能夠滿足運行要求，即能符合順向截車，最遠端反向截車以及轎內優先等基本控制原則，具有較高的實用性、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.
