Abstract
The invention relates to a method and device for dynamically adjusting the pressure intensity of an actual boiling point distillation instrument device, and the method comprises the following steps: fitting a linear equation according to a plurality of historical pressure intensity values and a plurality of historical toluene boiling point values corresponding to the historical pressure intensity values by adopting a least square method to obtain the linear equation; substituting at least part of the historical pressure values in all the historical pressure values into a linear square; constructing an input sequence by using the plurality of fitted toluene boiling point values, performing causal convolution processing on the input sequence to obtain a causal convolution value at a prediction moment t, and taking the causal convolution value at the prediction moment t as a y value of a linear equation to calculate a pressure value corresponding to the causal convolution value at the prediction moment t; and when the prediction time t is reached, if the pressure intensity value corresponding to the causal convolution value at the prediction time t is determined to be out of the toluene boiling point standard range, adjusting the pressure intensity of the true boiling point distillation instrument device to the pressure intensity value corresponding to the causal convolution value at the prediction time t, thereby solving the technical problem of hysteresis caused by manual adjustment.
