Design of PC Computer Temperature Control System on Pipy Resistance Furnace

This paper introduces a temperature control system on pipy resistance furnace which is composed of PC computer, and describes the structure and function of the system function, the design of hardware and software. CRT display is adopted and interface is devised in Chinese in the system. The control parameters can be displayed directly and adjusted on line. The change tendency curve of temperature and its passed curve can be showed. All modularized program of the system is devised with C|language, which is simply in structure and easy in realization.
