摘要： A method and a device which can be used to measure the moisture content and the internal structure of material on a tobacco bale (12), or of a bulk volume of material such as loose tobacco leaves (14), by using microwave radiation. A microwave radiation source (28) is located on one side of the tobacco, such as the tobacco bale, and an antenna (30) is located on the opposite side of the bale. The radiation source beam (32) is transmitted through a portion of the bale and is received by the receiving antenna (36), which then produces a signal (38). This signal is used to determine the moisture content of that portion of the bale and the mass uniformity of the bale. In addition, the methods and devices described herein can also be used to measure the moisture content of a bulk volume of loose tobacco leaves, for example as these leaves travel through a silo. Also, in a method for analyzing the internal structure of packaged tobacco, the internal structure is analyzed to detect the presence of any foreign objects or matter in packaged tobacco, as well as to confirm the presence of tobacco material throughout the package. The structural data is collected from the received and/or reflected microwaves, which are also analyzed to determine the moisture content. The raw structural data are then analyzed with detection, classification, and/or decision algorithms for analysis of the raw data. Preferably, the data analysis is based on pairs of attenuations (42) and phase shifts (44) obtained by passing, microwaves at a plurality of frequencies through the package of tobacco which features foreign matter or objects, collectively termed "foreign components" and/or non-uniformities. This unique method enables achievement of high levels of accuracy and precision in detection and classification of the sample, in general, and of the foreign components and/or non-uniformities, in particular.
摘要翻译：一种方法和装置，可用于通过使用微波辐射来测量烟草包（12）上的材料的水分含量和内部结构，或松散烟叶（14）等体积的材料。微波辐射源（28）位于烟草的一侧，例如烟草捆，天线（30）位于捆包的相对侧。辐射源光束（32）通过部分捆包传输，并被接收天线（36）接收，然后接收天线（36）产生信号（38）。该信号用于确定捆包部分的含水量和捆包的质量均匀度。此外，本文所述的方法和装置也可以用于测量松散烟叶的体积体积的水分含量，例如当这些叶子通过筒仓时。此外，在分析包装烟草的内部结构的方法中，分析内部结构以检测包装烟草中任何异物或物质的存在，以及确认烟草材料在整个包装中的存在。从接收和/或反射的微波收集结构数据，这些微波也被分析以确定含水量。然后利用检测，分类和/或决策算法对原始结构数据进行分析，以分析原始数据。优选地，数据分析基于通过以多个频率通过包含异物或物体的烟草包裹（统称为“外来部件”）和/或多个频率的多个频率通过微波而获得的衰减对（42）和相移（44）或非均匀性。这种独特的方法能够在一般的检测和分类检测和分类方面实现高水平的准确性和精度，特别是能够实现外来成分和/或不均匀性。
