摘要
    随着电子技术的发展，电子计算机已经用于温室控制环境。控制系统由中央控制装置、终端控制设备、传感器等组成。单片机的应用越来越广泛，我们可以把它应用在温度控制领域，有着重要的意义。
    目前有许多用电加热的设备，若是用人工去做温度的控制是十分麻烦的而且存在许多的问题。对此我们采用了单片机做控制不但制作简单而且使用非常的方便实现了智能化，这样可以大大的提高工作的效率。
    本课题是设计基于单片机的温室电炉的控制系统，采用了单片机AT89S51、温度传感器DS18B20进行温度采集并用数码管显示温度，而且该系统具有上下两度温差出现时候自动报警功能。
    这种系统具有很实用的价值，如现在我们的农业大棚可以利用此系统进行温度的智能控制。

关键字：AT89S51、电炉、温度传感器

Abstract
    Along with electronic technology's development, the electronic accounting machine already used in the greenhouse control environment. The control system by the central control installment, the terminal control equipment, the sensor and so on is composed. Monolithic integrated circuit's application is getting more and more widespread, we may apply it in the temperature control domain, has the vital significance. has at present many uses electricity the heating equipment, if with artificial makes the temperature the control is very troublesome and has many problems. Regarding this not only we used the monolithic integrated circuit to make the control to manufacture simply moreover use the unusual convenience to realize the intellectualization, like this might the big enhancement work efficiency. this topic is the design based on monolithic integrated circuit's greenhouse electric stove's control system, used monolithic integrated circuit AT89S51, temperature sensor DS18B20 to carry on temperature gathering and with the nixietube demonstration temperature, moreover time this system had the high and low twice temperature difference appeared the auto-alarm function. this kind of system has the very practical value, if our agricultural big awning may use this system now to carry on the temperature the intelligent control.

key words: AT89S51, the electric stove, the temperature sensor
