Introduction
PLC-Programmable Logic Controllers are widely used in recent years the field of industrial control Such as metallurgy, steel, production lines, etc Its main feature is its stable performance, high control precision and easy maintenance. With PC connection, compiled in the production process according to the corresponding program will convert digital signals into analog signal input commands output instructions to control the implementation of components to achieve automatic control purposes. Currently, the main aspects of the music program-controlled fountain imported lighting console and its matching control decoder, once the failure is not easy to repair, the price is more expensive. Using PLC technology, you can use an ordinary PC to replace imported lighting control, easy maintenance, low cost PLC article on how to use music technology to analyze the problem of program-controlled fountain.


引言
PLC-Programmable Logic Controllers(可編程邏輯控制器)近年來被廣泛應(yīng)用于工業(yè)控制領(lǐng)域,如冶金、鋼鐵、生產(chǎn)線等等,其主要特點(diǎn)就是其性能穩(wěn)定、控制精度高、維護(hù)方便。通過與PC連接,根據(jù)生產(chǎn)流程情況編制相應(yīng)的程序,將數(shù)字信號(hào)的輸入指令轉(zhuǎn)換成為模擬信號(hào)的輸出指令,進(jìn)行控制執(zhí)行元器件實(shí)現(xiàn)自動(dòng)化控制的目的。目前,在音樂程控噴泉方面主要采用進(jìn)口的燈光控制臺(tái)及其相配套的解碼器進(jìn)行控制,一旦出現(xiàn)故障,不便于維修,代價(jià)比較昂貴。利用PLC技術(shù),就可以用普通PC將進(jìn)口的燈光控制臺(tái)進(jìn)行替換,維護(hù)簡(jiǎn)便,成本較低,本文就如何利用PLC技術(shù)實(shí)現(xiàn)音樂程控噴泉的問題進(jìn)行剖析。
