Abstract:In the manufactured products and the family electric appliance, must use the constant temperature system frequently, but these constant temperature system's performance plays the very vital role frequently to these product's overall performance, this practice design uses the Chinese nation series W77E58 monolithic integrated circuit to carry on the control to the thermostat, and 51 development software policy leaves through Keil has the interactive observation system, has solved in the constant temperature system the interaction control question
key word: The monolithic integrated circuit constant temperature observation computer hardware technology experiments the Keil51 application system
