The Research&Design Of Rubber Vulcanizing Autocontrol System Based On STM32

In rubber vulcanization processing，the vulcanization is an important phase.The qualityof rubber vulcanization depends on curing conditions(temperature, pressure and time).Because in the actual production process fluctuations in temperature and pressure whichoperators can’t accurate grasp makes that it’s unable to ensure accurate vulcanization time andowe vulcanization or after vulcanization. Owe vulcanization makes products has becomesoft,and after vulcanization makes products has become stiff. They both have a bad effect ontire quality and cause serious waste of raw materials. Therefore, the precise control of curingconditions in the production of rubber products is an important technology.This paper analyzes the PID control principle and fuzzy control theory according to thecontrol precision requirements of tank vulcanizing machine’s temperature, pressure and time inrubber vulcanization process and designs the fuzzy self-adaptive PID control algorithm usingthe fuzzy control to dynamically modify the PID parameters,proofs that fuzzy adaptive PIDcontrol method is very short to adjust the time and small overshoots, and has good dynamiccharacteristic, good adaptability and robustness through the simulation in matlab.This paper puts forward the analysis for tank vulcanizing machine process correspondinghardware and software design and selects STM32which is based on ARM32bits CORTEX-M3core,using AD693application-specific integrated sensor chip and STM32’s AD conversionmodule and selecting DAC902current output type analog-to-digital conversion chip for outputcontrol.The paper Chooses open-source embedded operating system μC/OS, designs the relatedtasks which are scheduled by μC/OS, guarantees the task of real-time.
