Abstract: Aiming at the problem about the effective control of thermal oil temperature and efficiency, based on the ordinary PID control algorithm and fuzzy control algorithm based on rule table were studied, the temperature control system of temperature acquisition module, temperature display module, sound and light alarm module, the heating module were improved, the working principle of temperature control system including the fuzzy control method, pulse modulation method were analyzed. A kind of based on 89C52 and Marine paint heat conduction oil temperature control based on fuzzy control system was put forward, Proteus simulation platform was used to construct the simplified model of the temperature control system, based on the ordinary PID algorithm and fuzzy control algorithm based on rule table are simulated respectively. The results indicate that, the fuzzy control algorithm based on rule table of heat conduction oil temperature control system performance is better, more efficient, has the good effect of the temperature control, the system can occur at temperatures of abnormal sound and light alarm and command system to stop working, and can meet the needs of actual production and processing.
