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
