Abstract

This invention relates to the technical field of oven heating temperature control, specifically to a method and system for controlling the heating temperature of an industrial hot air circulating oven. The method includes the following steps: applying a detection signal to the heating component and / or airflow circulation component of the oven; acquiring temperature response information from the output of a single temperature sensor inside the oven; performing feature analysis on the temperature response information to obtain the oven's response characteristics to the detection signal; comparing the response characteristics with a preset reference mode to infer the heat distribution and airflow organization state inside the oven; adjusting the power output of the heating component and / or the operating parameters of the airflow circulation component based on the inferred heat distribution and airflow organization state; and, in continuous production mode, adjusting the initial thermal field inside the oven before material loading based on the inferred heat distribution and airflow organization state. This application can improve the uniformity of material drying and product quality.
