Temperature control system used single chip computer

ABSTRACT

The temperature is constantly in the daily life of physical and temperature controls in various fields have a positive meaning. A lot of businesses have a lot of power heating equipment, such as that used for the heat treatment furnace, for melting metal crucible resistance heaters and the various uses of temperature bins, SCM using their right to control not only easy to control, simple, such as the characteristics of flexibility, but can also significantly increase the temperature was charged with the technical indicators, which can greatly enhance the quality of the products. Therefore, intelligent temperature control technology is being widely adopted.

The temperature was designed with the now popular AT89S51 SCM, and with DS18B20 digital temperature sensor, The temperature sensor can set up their own temperature collars. SCM will detect that the temperature of the input signal and temperature, the lower comparisons this judgment whether to activate the relay to open the equipment.

The design also includes commonly used digital display and control state lights commonly used circuit, making the whole design more complete, more flexible. The design has been applied to someone, to someone intelligent temperature control.

【Key word】 Temperature， AT89S51， SCM， Control， Simulation
