摘要

現(xiàn)代化的影劇院，需要現(xiàn)代化的舞臺(tái)設(shè)備。才能在科學(xué)技術(shù)日益更新的今天，憑借自身的實(shí)力吸引更多觀眾。而在現(xiàn)代化舞臺(tái)設(shè)備中占舉足輕重地位的設(shè)備，便是舞臺(tái)吊桿。舞臺(tái)吊桿是影劇院起吊景物、幕布、燈光等專用設(shè)備，此設(shè)備首先應(yīng)安全，同時(shí)也應(yīng)具備靈活，操作簡(jiǎn)單、外形美觀等。只有更新才適應(yīng)未來發(fā)展的需要。因此笑者設(shè)計(jì)一套舞臺(tái)吊控制系統(tǒng)。

本文分析了舞臺(tái)吊桿控制系統(tǒng)的主要信息，以模塊化設(shè)計(jì)思想，利用手動(dòng)和自動(dòng)控制電路來實(shí)現(xiàn)其功能。舞臺(tái)吊桿控制系統(tǒng)的自動(dòng)功能由控制器PLC來控制變頻器實(shí)現(xiàn)，手動(dòng)功能通過接觸器邏輯電路來實(shí)現(xiàn)。每根吊桿用手動(dòng)按鈕來控制其上升和下降。

課題的第一部分介紹了舞臺(tái)吊桿控制系統(tǒng)發(fā)展?fàn)顩r，變頻器發(fā)展?fàn)顩r，PLC發(fā)展?fàn)顩r及課題研究的意義。第二部分介紹了舞臺(tái)吊桿控制系統(tǒng)的整體設(shè)計(jì)。第三部分介紹了舞臺(tái)吊桿控制系統(tǒng)的實(shí)現(xiàn)，這是系統(tǒng)的核心部分。第四部分介紹了系統(tǒng)的結(jié)論。

The control system of the stage boom design

Abstract

Modern movie theaters need modern stage equipment. In an increasingly science and technology can update today, with their own strengths to attract more viewers. In modern stage equipment for a status of the equipment is launching stage. Stage bar is lifting features movie theaters, theater curtain, lighting, and other special equipment, the equipment should first security, but also should be flexible, simple to operate, shape aesthetic. Only updated to meet the needs of future development. So laugh design a set of control systems.

This paper has analyzed the stage bar control system main information, the modular design thought, the use manual and the automatic circuit realizes its function. The stage bar control system automatic function controls the frequency changer realization by controller PLC, the manual function realizes through the contact device logic circuit. Each bar controls its rise and the drop with the manual button.
Part I introduced stage bar control systems development, transducer development, PLC development and task research significance. Part II introduced the overall design stage bar control systems. Part III introduced stage bar control system’s achieved; this is the core of the system. Part IV introduced system’s conclusion

Key words：Stage Bar ;Control system ;Inverter ;PLC
