Two-Grade Temperature Control System for Computer and Single Chip Microcomputer

Temperature is a key parameter in the practical manufacturing process,this paper introduces the control principle,hardware structure and software design of the temperature control system,which applied microcomputer and computer of single chip.The updevice is used by a microcomputer,the whole control process is observed obviously by changing curve showed on monitor,and the influence of parameter changing on the system can be demonstrated also.As a key point,the(down)device is controlled by a single chip computer.It uses serialport to realize the asynchronous communication.This system has applied in practical teaching course,the result proves a good performance.
