Abstract :
The paper aimed at tobacco parching house and introduced a smart temp-humidity control system for some tobacco planted area in Guizhou province. Writer adopted fuzzy-PID error control technology and adjusted power-weight of fuzzy and PID control on-time based on variety of measurement and setup value. Writers adopted digital temperature sensor, PHILIPS LM75A and AT89C51 to construct controller of fuzzy parameter self-adjusting and PI. Then at 32degC to 67degC, the system realizes control with optimal temp-humidity curve of tobacco parching. System control the tobacco´s changing during firing. The system solves these problems that because of great heat inertia, long time transmission of measure, and lagging of current on-off control, the traditional temp-humidity control system is difficult to actualize precision testing and synchronous control. The system has low overshoot, good robustness, strong adaptability, and short time-regulation. Thus it improves quality of tobacco
