Embodiment 1
[0037] figure 1 Shown is a schematic flow chart of the identification method of the abnormal working condition of tobacco leaf threshing and redrying according to an embodiment of the present invention, and the concrete steps include:
[0038] Step S11: Acquire various online working condition data in a preset period during the process of threshing and redrying tobacco leaves. In a preferred embodiment of the present embodiment, the tobacco leaf threshing and redrying process includes a plurality of processing steps. The plurality of processing procedures include a primary leaf moistening process, a secondary leaf moistening process, a stalk separation process and a redrying process. Preferably, the online working condition data includes: flow rate, drum frequency, tobacco leaf moisture, rotational speed of threshing and threshing, image area of tobacco leaves, frequency of the main mesh belt motor frequency for redrying, and the like. The flow includes the instantaneous f...
Embodiment 2
[0049] The embodiment of the present invention is a data link application method based on the identification of abnormal working conditions of tobacco leaf threshing and redrying, comprising the following steps:
[0050] Step S21: Based on the normal working condition data set, establish the first correspondence relationship pedigree between the data chain of the tobacco leaf threshing and redrying processing process and the working condition data. Preferably, the first corresponding relationship pedigree is established by a time axis method, and the time axis method forms a relatively complete first corresponding relationship pedigree according to the time sequence, which has the advantages of systematization, completeness and precision. It should be understood that the normal working condition data set involved in this embodiment refers to the normal working condition data set obtained by the method for identifying abnormal working conditions of threshing and redrying tobacco...
