【正文】 8 顯示的是在沒(méi)有使用控制器的情況下會(huì)發(fā)生的一些結(jié)果。 這些照片是控制線(xiàn)路的電圖表 ,包括感應(yīng)器，控制鍵和電的活瓣卷。 另外的一些輔助設(shè)施也包括在這個(gè)系統(tǒng)中 ,比如自動(dòng)機(jī)械 / 手動(dòng)調(diào)控器，他們可以使系統(tǒng)不斷的循環(huán)工作；兩個(gè)開(kāi)始控制鍵 ,他們能讓操作員手動(dòng)控制系統(tǒng)的開(kāi)始和停止，這樣就減少了發(fā)生意外事件的危險(xiǎn)。 6. 使用者變更例子規(guī)劃 氣流線(xiàn)圈在前面 已經(jīng)詳細(xì)說(shuō)明過(guò)：它可以讓我們了解到控制一個(gè)系統(tǒng)所需要的條件，那就是在系統(tǒng)的實(shí)際運(yùn)行中必須提供所有的功能設(shè)施。但是 ,如前面提到的那樣 ,使用一個(gè) PLC 或特定的控制器 , 這種控制就變得比較容易的，而且系統(tǒng)的精密性也會(huì)提高。 使用傳統(tǒng)的 PLC的 ,如圖 7， 8所示，在繪制接口處的電圖表時(shí)，要注意線(xiàn)路的邏輯。使用這種可編程的控制器 ,使用者必須知道運(yùn)行方法的觀念并且規(guī)劃每個(gè)步驟的結(jié)構(gòu)。 那就是說(shuō)，使用傳統(tǒng)的 PLC ，使用者清楚各個(gè)操作之間的關(guān)系。一般情況下，使用者可以在接口上運(yùn)行一個(gè)模擬程序?qū)ふ疫壿嬌系腻e(cuò)誤同 之前所述的一樣，新的編程允許每一步驟的結(jié)構(gòu)被分割。 序列獨(dú)自被定義，但每一步驟只被輸入和輸出端描述。 7. 結(jié)論 這種控制器是專(zhuān)門(mén)為這一項(xiàng)目所設(shè)計(jì)的。顯示了一個(gè)以微控制器為基礎(chǔ)的非常有用的可編程的控制器。它不需要為了獲取微控制器里的資源而安裝外部記憶器或外部的定時(shí)器。除了微控制器之外 ,只有少量的零部件執(zhí)行一些如輸出，輸入，類(lèi)比輸入 ,顯示接口和連續(xù)運(yùn)行的情況等功能。 單獨(dú)使用內(nèi)部記憶 ,我們可以控制一個(gè)有 48個(gè)步驟的氣流系統(tǒng)，但是如果使用一個(gè)比較簡(jiǎn)單的系統(tǒng)，就會(huì)達(dá)到 60個(gè)步驟 .控制器的變成不使用 PLC 語(yǔ)言 ，而是用一個(gè)比較簡(jiǎn)單的和直覺(jué)的結(jié)構(gòu)。利用電氣系統(tǒng)，我們的項(xiàng)目應(yīng)用了相同的技術(shù)，但同時(shí)我們的設(shè)計(jì)更加直接。 一種 非常簡(jiǎn)單的機(jī)械語(yǔ)言能讓設(shè)計(jì)者用四或五個(gè)位元組定義步驟所有結(jié)構(gòu)構(gòu)成。這就要看他使用控制器的經(jīng)驗(yàn)如何了。這種控制器雖然不能和商業(yè)的 PLC 相比，但是它原本就是為特定的的目的而設(shè)計(jì)的，所以很難說(shuō)哪一個(gè)好哪一個(gè)壞?？傊覀兊倪@個(gè)系統(tǒng)是基于微控制器而設(shè)計(jì)，簡(jiǎn)單快捷。 附件 2：外文原文 Programmable Controller Designed for Electropneumatic Systems Summary this item is mainly the procedure which studies electricity system and in brief valid control current of air to launch machine to patibly flow the appearance of system. It of the fulfillment foundation include according to the control procedure of particularly have of the current of air controller, automation design, current of air system and design according to the electronics of the tiny controller. 1. Brief introduction The automation which uses an electricity technique mainly constitutes to. from 3 part: Launch machine or motor, sensor or button, the form is zero partses such as the control of flower petal. Now, greatly part of system logic the controllers of the operation drive all procedure logic controller (PLC) replace. PLC sensor and switch39。s aring an importation to carry, but launch the direct control valve of machine is an exportation to carry and have an internal procedure to operate among them all circulate essential logic, imitate other devices like calculator, in fixed time machine etc., carry on a control to the whole movement appearance of system. Can according to need numerous time to establish and imitate thus of system, so all from PLC usage, this item contains vivid advantage. Therefore can save time, the danger of decrease error, in the meantime under the sistuation that use same material, it can be getting more precise. Many pany that is on the market used the PLC of normal regulations and it can not only control with the current of air system, but also can use various electricity equipments. PLC wide range of application, can be apply in much industry to produce medium, even used for safety and automation of building in. Because of above various characteristic, the PLC provided a lot of resourceses in somely physically appliedly, even include not a resources of control the system and the electricity system was a kind of application like the engineering of automation, the PLC usage is more expensive, particularly is to those small scaled systems. Aim at this kind of circumstance39。s a kind of viable way establish a controller that can provide particular size and function. This kind of controller can create according to the tiny controller. This kind of applies scope according to the tiny controller smaller, the machine that can used for a type perhaps can use to do a be like the mon PLC is similar and can be woven a distance of controller, so it can pass variable turn of logic procedure to carry on various homework. All of these characteristic basis concrete demand of dissimilarity but dissimilarity, concrete of design of empirical of dissimilarity but dissimilarity. But the main advantage of this kind of design lie in designing a personnel to understand an own controller very much, can freely control the big baby size of controller, change it of function. This means that this item contains more special, but in the meantime the control of system also from it of design control. 2. Electricity system People can find out to speak of in three preceding contexts from an automation of basic parts, the in addition is a logic circuit which controls system. Th
