Description: Introduction of the topic to the AT89C51 single-chip microcomputer as the core temperature control system working principle and design method. Temperature signal from temperature chip DS18B20 acquisition and digital signal transmission to the single-chip microcomputer. In this paper, the control system hardware components, including: temperature detection circuit, temperature control circuit, temperature display circuit, alarm circuit, and some interface circuits. Single-chip signals through the corresponding treatment in order to achieve the purpose of temperature control. It also illustrated the way in order to focus on the various parts of the circuit and software design of the modular structure here, the main modules are: the main program, a digital display subroutine, keyboard scanning and treatment Subroutine button, temperature-based set subprogram, and the DS1820 procedures.
