Software design for the system of bathing temperature
Abstract: The temperature is a very widespread and in common use diagraph parameter in the each realm of the work agriculture and modern science research development. For example:In metallurgy industry, chemical engineering produce, electric power engineering, deckle profession, the machine many realms such as manufacturing and food processing etc., the people all need to carry on the controls and examination to the each kind of heating stove, the hot processing stove, reactor and temperature in the boiler.
This time designs to examination the core with a machine of STC89C52 conduct and actions,through the hardware electric circuit manufacture and the software procedure establishment, realizes a temperature observation and examination system.The system spread the feeling machine to come to indirectly to measure the water temperature through a hot electric resistance, make use of to give or get an electric shock the bridge electric circuit to make it from the temperature change but causable electric resistance of variety change becomes the variety of the electric voltage, then pass the ICL7650 to carry on enlarge to the electric voltage signal that the sample come in, use a pair of integral calculuseses type ADC0804 to enlarge of electric voltage signal carry on the conversion of AD,then put them in the unit of STC89C52 to deal with it.
This system according to a design thought for turn of mold, completed the design of the system hardware part, give the design thought and block diagrams of the each system mold piece. This temperature regulating system can steer the sample switching of the figure accurately, the stability steers to heat, the examination process of the constant temperature, and can compare goodly request of satisfaction to accuracy of system.
