AI Technical Summary

Technical Problem

Existing technologies lack effective modeling and dynamic monitoring methods in the second stage of tobacco drying, resulting in difficulty in controlling moisture stability and making it impossible to adapt to process fluctuations of different batches and grades, thus affecting the consistency of tobacco quality.

Method used

An adaptive bandwidth method based on residual distribution is adopted. By continuously collecting data from the drying machine, performing data preprocessing and filtering, an adaptive drying moisture stability control model is constructed. The model monitors and triggers the adjustment of the cylinder wall temperature in real time to achieve closed-loop optimization control.

Benefits of technology

It enables online process stability assessment and closed-loop optimization control of moisture quality in the second stage of raw material production, supports iterative updates of new batch data, and is suitable for online production monitoring in intelligent tobacco manufacturing.

Abstract

The application discloses a kind of based on residual distribution adaptive bandwidth's cut tobacco moisture stability regulation method, comprising: S1, the cut tobacco process data of the whole cut tobacco process of past period of time cut tobacco machine is continuously collected;S2, the process data collected is continuously preprocessed according to the window length set, and form sampling point sequence data set;S3, the post-drying moisture change sequence data of each qualified batch in sequence data set is screened, and the preferred data set that meets " continuously rises and tends to be stable " is formed;S4, fitting processing is carried out to preferred data set to determine the regulation range of cut tobacco moisture stability;S5, the post-drying moisture average of current one described window length of cut tobacco machine cut tobacco second stage is collected in real time, whether in regulation range is judged, if exceed upper limit appears, then trigger cut tobacco machine cylinder wall temperature regulation mechanism;If exceed lower limit appears, then prompt that there is overdrying risk, start drying regulation mechanism;Form closed loop stability regulation.
