Abstract
The application relates to a detection method and system applied to a blown film forming device, which comprises the following steps: collecting parameter data of film thickness, temperature and airflow pressure in a blown film process; collecting change data of temperature and airflow pressure affecting sensor performance; establishing a mathematical model between the parameter data and the change data according to historical sensor data and historical change data; calculating a compensation factor according to the established mathematical model and real-time sensor data; correcting the output data of the sensor; setting target control parameter data, calculating the deviation between the compensated parameter data and the target control parameter data, generating a control signal and feeding back to the control system of the blown film forming device; the scheme analyzes the influence of environmental changes on the performance of the sensor, and performs real-time correction through a compensation algorithm, so that the key parameter data in the blown film process is more accurate, and the quality of the film and the stability of the production process are improved.
