Abstract
To effectively guarantee the grain drying temperature to keep in safe range, a downstream type corn drying tower temperature control system was designed combining the multi-sensor detection and the even putting fuzzy control technology. With AT89C51 as the development platform, and the programmable temperature sensor DS18B20 was used via a serial port communication and transport to the LabVIEW system. Moreover, according to the upper machine, the temperature was detected as the data for feedback system adjustment, and anti-saturation PID control algorithm, the size of single chip microcomputer output duty cycle was adjusted. Thus the drive circuit heat fan speed was controlled finally. Compared with the traditional device, this improved temperature control system contained a simple host interface, a flexible structure, a convenient debugging, an efficient and precious temperature detection and transformation.
