[0007]The moisture meter calibration system disclosed in the above documents has hysteresis, does not have the functions of material moisture prediction and early warning, and cannot verify the accuracy of the moisture meter online and in real time. And timely discover the abnormal situation of the moisture meter
Since the online tobacco moisture meter is an infrared detection device, its key components, light source and filter, are fragile parts. If the abnormal condition of the moisture meter cannot be found in time, the equipment instability will lead to tobacco quality accidents

Abstract
The invention discloses an online moisture meter calibration method for a tobacco shred making link. The method comprises the following steps: step 1, data acquisition; 2, setting a production line moisture meter; 3, establishing a model, namely establishing a moisture meter verification model in sections according to a definition result; 4, establishing a moisture prediction module, and performing real-time segmented prediction on the moisture of the material by combining historical batch parameters according to each moisture meter verification model; and step 5, establishing an early warning module, comparing and analyzing the predicted value and the measured value, and performing early warning and display on the moisture meter with the predicted value exceeding the material moisture deviation requirement. The invention aims to provide an on-line and real-time verification means for the moisture meter on the cut tobacco production line so as to prevent quality accidents of cut tobacco caused by unstable equipment.
Description
[0001] This application is a divisional application of the application number: 202010662317.7, the name of the invention: the invention application of the online moisture meter calibration system in the process of tobacco silk making. technical field [0002] The invention relates to the tobacco industry, in particular to the field of on-line moisture meter calibration in the process of cigarette silk making, in particular to an online moisture meter calibration method in the process of cigarette silk making. Background technique [0003] In the tobacco production process, the silk production process is a very important part. It is the process of making the tobacco into qualified shredded tobacco according to the physical and chemical properties of the tobacco raw material and according to certain procedures. In the cigarette production process, the silk making process is the longest, the most complicated, and the most types of equipment. The existing silk-making workshop pr...
