摘要
　　　
本文詳細(xì)討論舞臺燈光的基本知識及發(fā)展和基于s7-200PLC的控制技術(shù)，介紹了舞臺燈光的PLC控制系統(tǒng)的設(shè)計方案及其控制原理，用多種指令實(shí)現(xiàn)對舞臺燈光中24只燈的控制，通過對時間繼電器時間控制的改變可實(shí)現(xiàn)不同的燈光效果。舞臺燈光也叫“舞臺照明”，簡稱“燈光”，舞臺美術(shù)造型手段之一。PLC簡單易學(xué),可靠性高。其不僅具有開關(guān)量和模擬量的控制功能，還具有更強(qiáng)的數(shù)字計算能力，它的通信功能和模擬量處理能力更強(qiáng)大。它比小型機(jī)的指令更豐富，適用于復(fù)雜的邏輯控制系統(tǒng)以及連續(xù)生產(chǎn)過程控制場合。

Abstract:

This paper discusses the basics of stage lighting and the development and S7-200 PLC-based control technology, introduces the lighting of the PLC control system design and control theory, using a variety of stage lighting 24 water lights, controlled by time relay time of change in different lighting effects can be realized. Lighting is also called "stage lighting", referred to as "light", stage art form one of the means. PLC is easy to learn, and high reliability. It not only has the switch and analog control functions, also has a number of more computing power, its communication functions and analog processing more powerful. It is richer than the minicomputer instruction for complex logic control system and continuous process control situations
