[0060] as attached figure 1 and 2 S1 shown: collect the industrial parameter characteristic data of cement rotary kiln at time interval T such as (feeding amount of medicine, coal feeding amount, temperature of raw materials entering the kiln, secondary air temperature, rotary kiln speed, etc.), and collect the previous sampling time at the same time The fire watching video of the rotary kiln corresponding to the time span T up to the current sampling moment. And the strength of the cement at the corresponding time point after 3 days was obtained through the later laboratory test as the clinker quality index, which is also the monitoring index of this soft sensor model.
[0061] S2: Perform dual-channel concurrent extraction of time-series feature data on the fire watching video and industrial parameter data. Among them, the fire-watching video data adopts the cross-frame fusion convolutional neural network (DilatedConvolution fusion neural network, DCFNN) proposed by the pr...
