(毕业论文)温控加热器电路的设计与制作
摘 要
随着科技的发展，工业自动化已经是各个厂家所要追求的方向。自动控制这里定义为：利用各种测试方式，测得操作程序内变量的状况，然后自动加以适当的调整，使操作符合原定的程序。
其中温度控制器就是自动控制的一个应用。生活中到处可以看到温度控制器的实物。比如电饭煲、热水器等等的生活用品。本文主要是通过对温控加热器的研究了解到温控加热器中的各个部分有着怎样的用途。懂得温控加热器的原理，并用单结晶体管和可控硅为主要器件设计出一个温控加热器。
关键词：温度控制器、单结晶体管、可控硅、温度传感器、热敏电阻
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
