Description: Oven as an important production tool widely used in industrial production and food processing and other fields. Oven temperature is an important indicator of the production process, for the temperature control performance to a large extent determine the product quality and production efficiency.
System P89V51RD2 microcontroller as its core achieved a temperature acquisition, PID control, human-machine dialogue, and timing functions. Due to noise interference and the actual existence of which occur in the sampling process sampling signal and the actual signal biased phenomenon, caused in this regard in order to reduce measurement error, the system uses 16 sub-samples averaging method of sampling values smoothing filter, then the value of the filter look-up table to get the actual temperature. In the control using PID control, temperature control with a lag, inertia and other characteristics, PID operation in the integral term steady-state error can be eliminated, while the differentia
