Unable to realize the temperature measurement and control of data. This system needle some economical field temperature control but required for the problem design, AT89C51 single chip microcomputer as the core to realize the automatic temperature control, using digital temperature sensor DS18B20 collecting temperature information, System USES two LED digital tube to display the real-time temperature monitor, through temperature display switch button can also display the user setting temperature value. In order to simplify the hardware structure of the keyboard, the system adopts hand dial button. Temperature control system, and adopted with zero passage trigger bidirectional thyristor trigger circuit, his design based on single chip microcomputer complete design of the platform. This design through simulation to design the index in this paper, the design scheme of temperature class design has reference value.
