Cut tobacco blending process electronic belt scale abnormity on-line monitoring method

Abstract

The invention discloses a cut tobacco blending process electronic belt scale abnormity on-line monitoring method comprising the following steps: using material flow collected by a cut tobacco blending process electronic belt scale as a data source, constructing a subspace model based on reconstruction constraint, and solving an initial projection matrix in combination with a target function of the model; then, optimizing the target function based on a recursive Lasso regression model, and finely adjusting the projection matrix according to new data currently collected by the electronic belt scale, the initial projection matrix and the optimized target function, so that the current sampling data obtain an optimal subspace distribution position; and finally, comparing the subspace distribution based on the current data with a subspace distribution rule obtained based on the data sample so as to judge whether the electronic belt scale is abnormal or not. The method has the advantages of being high in accuracy, convenient to operate and capable of tracking in real time, objective and reliable decision support is provided for on-line monitoring of the multiple parallel electronic belt scales in the tobacco shred blending process, and then the stable metering performance and the blending precision are guaranteed.

Description

technical field [0001] The invention relates to the field of cigarette industry, in particular to an online monitoring method for abnormalities of electronic belt scales in the shredded tobacco blending process. Background technique [0002] There will be abnormalities in the use of measuring instruments. If the abnormalities are not checked and repaired in time, the accuracy of the measuring instruments will be affected, which will bring huge hidden dangers to the subsequent industrial production process and increase The cost of administrative expenses for the business. In order to ensure the accuracy of the measurement data of the measuring instruments, it is necessary to monitor the data measured by the measuring instruments in real time during the working process of the measuring instruments. Once an abnormality occurs, such as data jumps, etc., it is necessary to judge whether the measuring instrument is faulty or the adjustment of the production conditions; if the mea...
