電梯控制系統(tǒng)設(shè)計
摘要：電梯是一種特殊的起重設(shè)備，在運行中不但具有動能，而且具有勢能。電梯驅(qū)動電動機經(jīng)常處在正轉(zhuǎn)和反轉(zhuǎn)、起動和制動過程中。電梯由轎廂及配重、拖動電動機及減速傳動機械、井道及井道設(shè)備、召喚系統(tǒng)及安全裝置構(gòu)成。轎廂是載人或裝貨的部位，配重是為了改變電梯電動機負載的特性以提高電梯安全性而設(shè)置的。電梯的運行要求穩(wěn)定、可靠、安全，用PLC完成對電梯系統(tǒng)的控制是十分合適的。

Elevator Control System
ABSTRACT: Elevator is a special lifting equipment. Not only has the kinetic energy in operation, but also potential. Elevator drive motor are transferred and often is reverse,the process of starting and btaking. Elevator car and counterweight, drag the motor and the gear reducer transmission machinery, wells road and wells road equipment, call systems and safety devices comstitute. Car is the site of a manned or loading. Weight is to change the lift characteristics of the load motor to improve security and set the lift. Elevator operation for stability, reliability and security. Complete with PLC control of the elevator system is very suitable.
