摘要
温度是日常生活中无时不在的物理量,温度的控制在各个领域都有积极的意义。很多行业中都有大量的用电加热设备,如用于热处理的加热炉,用于融化金属的坩锅电阻炉及各种不同用途的温度箱等,采用单片机对它们进行控制不仅具有控制方便、简单、灵活性大等特点,而且还可以大幅度提高被控温度的技术指标,从而能够大大提高产品的质量。因此,智能化温度控制技术正被广泛地采用。
本温度设计采用现在流行的AT89S51单片机,配以AD590温度传感器,是一个利用温度来实现简单智能控制的例子。它完成了从温度的采集、转换、显示以及控制的一系列任务。由于时间关系,本文并未深入探讨温度的具体实例。例如根据温度来控制热水器、电风扇等与温度有关的设备。但是它提供了一个通过温度来控制设备的基本思想和原理。相信能在实际应用中为我们的生活带来更大的便利。

Abstract
Temperature is the ever-present in daily life physical quantities, temperature control in various fields have positive significance. A lot of businesses have a lot of electric heating equipment, such as for heat treatment furnace for melting the metal crucible resistance furnace and a variety of different uses of the temperature boxes, using SCM to control them is not only easy to control, Simple, flexibility and other characteristics, but also can greatly improve the temperature was charged with technical indicators, which can greatly improve product quality. Therefore, intelligent temperature control technology is being widely adopted.
The temperature of the design with the now popular AT89S51 microcontroller, together with the AD590 temperature sensor, is a smart use of simple temperature control example. pleted the acquisition of temperature, conversion, display and control a series of tasks. Because of the time, this article does not explore in depth the temperature of the concrete examples. For example, under temperature control, water heaters, electric fans and other equipment related to temperature. But it provides a temperature control device through the basic ideas and principles. I believe in practical application to ou
