基于 PLC 的舞台灯光设计【摘要】本文详细讨论舞台灯光的基本知识及进展和基于 s7—200PLC 的控制技术，介绍了舞台灯光的 PLC 控制系统的设计方案及其控制原理，用多种指令实现对舞台灯光中 24 只灯的控制，通过对时间继电器时间控制的改变可实现不同的灯光效果。舞台灯光也叫“舞台照明",简称“灯光”,舞台美术造型手段之一。PLC 简单易学,可靠性高。其不仅具有开关量和模拟量的控制功能，还具有更强的数字计算能力，它的通信功能和模拟量处理能力更强大。它比小型机的指令更丰富,适用于复杂的逻辑控制系统以及连续生产过程控制场合。关键词:舞台灯光 PLCAbstract: 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 Key words: Stage lighting PLC 目录引言......................................................................11 可编程控制器的概论......................................................11。1 PLC 的概述..........................................................11.2 PLC 的由来...........................................................11。3 PLC 的定义..........................................................21。4 PLC 的构成..........................................................21.5 PLC 的工作原理.......................................................3...
