Application of Data Fusion Technology in Ice Cream Control System of Pouring Model

In this paper, the variance of two temperature observations is weighted and fused with the pouring model ice cream maker. The temperature data with large variance is given smaller weight and the variance with small variance is given larger weight. This data fusion method can obtain more reliable measurement results than the arithmetic mean. With the design method of SCR sequence control chart, the strategy to control overheating is compiled, and the intelligent PID control of R404a flow is carried out. The table of main data points, real-time monitoring chart of production and historical trend curve are given, which greatly increases the authenticity and accuracy of data and achieves ideal control effect.
