C8051F单片机通用温度监控器的设计+电路图+源程序 摘要：温度监控器在人民日常生活中有着非常广泛的应用，它在冰箱、空调、电脑 等电气电子设备中占着尤为重要的地位。众所周知的，如果一个电器的某个关键 系统温度过高，一定会导致电器的烧毁，这正是需要温度监控器的原因。
随着现电子代业科技的发展，温度监控器不仅仅是在家电领域中起作用，更 是将涉及的范围扩大到了现代自动机化械生产、医疗、核研究、宇宙探测等等各 个不同范畴的领域，在诸如此类的领域中，没有准确的对仪器仪表的温度检测，可能随时会导致难以预计的严重后果。
在这个设计中，我将要设计一个有温度监控功能的电路，这个电路采用了以滑动变阻器模拟热敏电阻的形式进行温度监控， 而热敏电阻的感温形式虽然灵敏 度不及热敏二极管，不过在一般的温度控制上还是能很出色的投入实际应用的。 做这个课程设计，使我更加熟悉了二极管、稳压管、运算放大器等元器件的原理 和应用，真正做到了把专业课中学到的知识用到了实际当中。

The design of the universal temperature monitor
Abstract: The temperature monitor has a very wide range of applications in the everyday life of the people, it occupies an especially important position in refrigerators, air conditioners, computers and other electrical and electronic equipment. As we all know, if a critical system of an electrical temperature must cause electrical burning, which it is necessary for the temperature monitor.
With the current development of the electronic generation of technology, the temperature monitor function not only in the field of home appliances, is the scope of expanding to modern automatic machine firearms production, medical, nuclear research, space exploration and so on various aspects of the field, in areas such as these, there is no accurate on temperature detection instrumentation, may at any time will result in serious consequences difficult to predict.
In this design, the I will be designing a temperature monitoring function of the circuit, this circuit using a thermistor in the form of analog slide rheostat temperature monitoring, and the thermistor temperature sensing form although the sensitivity is less than the thermal diode, but in the temperature control is still very well put into practical application. Do the curriculum design, so I am more familiar with the diode, the regulator, the principles and applications of the operational amplifier and other components, specialized courses learned knowledge is used in practice, truly.
