(畢業(yè)論文)溫控加熱器電路的設(shè)計(jì)與制作


摘 要
隨著科技的發(fā)展，工業(yè)自動(dòng)化已經(jīng)是各個(gè)廠家所要追求的方向。自動(dòng)控制這里定義為：利用各種測(cè)試方式，測(cè)得操作程序內(nèi)變量的狀況，然后自動(dòng)加以適當(dāng)?shù)恼{(diào)整，使操作符合原定的程序。
其中溫度控制器就是自動(dòng)控制的一個(gè)應(yīng)用。生活中到處可以看到溫度控制器的實(shí)物。比如電飯煲、熱水器等等的生活用品。本文主要是通過對(duì)溫控加熱器的研究了解到溫控加熱器中的各個(gè)部分有著怎樣的用途。懂得溫控加熱器的原理，并用單結(jié)晶體管和可控硅為主要器件設(shè)計(jì)出一個(gè)溫控加熱器。
關(guān)鍵詞：溫度控制器、單結(jié)晶體管、可控硅、溫度傳感器、熱敏電阻
 
 
Abstract
With the development of science and technology, industrial automation manufacturers are the direction to be pursued. Automation here is defined as: use of the test variables measured in the state of operational procedures, and then be appropriately adjusted automatically, so that the operators comply with the original procedure.
Temperature controller which is an application of automatic control. We can see the kind of temperature controller everywhere in the life. Such as rice cookers, water heaters, daily necessities and so on. In this paper, mainly through the study of temperature-controlled heater temperature-controlled heater that's how the various parts of a purpose. Understand the principle of temperature-controlled heater and a single bipolar transistor and THYRISTOR devices as the main design of a temperature-controlled heater.
Keywords: temperature controller, a single bipolar transistor, SCR, temperature sensor, THERMISTOR
