Abstract
The single chip microcomputer is required extensively in measurement and control systems, The design of single-chip’s temperature control system is introduced from hardware and software, and simply explains how to actualize the temperature control. The hardware principle and software case fig are described. Some important techniques in a design scheme of the hardware and the software of the temperature control by single-chip microcomputer are introduced.
The system mostly takes AT89S52 single-chip microcomputer as core, it is structured by sensor circuit, V/F conversion circuit, show and control circuit, feedback circuit and so on.
Design of the system will not only compact, reliable performance, but an effective control system to improve the real-time control and precision, thus greatly improving the temperature control of the degree of automation; applies not only to control temperature, but also applies to the industrial temperature monitoring and control.
