This is because the weight and density of the cotton bale M increase, and the moisture content per unit volume increases, but in fact the real moisture content of the cotton bale M is still 6%, and the weight and density of the material in the actual production cannot be kept strictly consistent , resulting in inaccurate final measured moisture content

The invention relates to a microwave moisture measurement, device and equipment and a storage medium. The method in an embodiment comprises the following steps: acquiring material type information; extracting a preset number of frequency information from a frequency interval corresponding to the material type information according to the material type information; controlling a microwave emitting antenna to sequentially emit microwave signals of the frequencies corresponding to the preset number of the frequency information; acquiring the microwave signals received by a microwave receiving antenna; determining the phase difference and damp decrement of the microwave signals of each frequency received by the microwave receiving antenna corresponding to the microwave signals of each frequency emitted by the microwave emitting antenna; with the phase difference of the microwave signals of each frequency as a first vector and the damp decrement as a second vector, overlapping the first vector with the second vector, so as to respectively obtained a microwave signal vector of the microwave signals of each frequency; and determining the water content of a to-be-tested material according to the microwave signal vector of the microwave signals of each frequency. According to the scheme of the embodiment, the accuracy of the microwave moisture measurement is increased.
Description
technical field [0001] The invention relates to the technical field of moisture measurement, in particular to a microwave moisture measurement method, device, equipment and storage medium. Background technique [0002] Microwave moisture measurement technology is more and more commonly used in various industries. It can monitor the moisture content of materials in the production process in order to improve product quality and effectively control the production process, thereby saving costs and improving production efficiency and production benefits. [0003] The basic principle of microwave moisture measurement is: the microwave emitted by the transmitting antenna penetrates the material under test and reaches the receiving antenna, and the microwave received by the receiving antenna is fed back to the evaluator, and the evaluator analyzes the moisture content of the material under test. When the microwave penetrates the material, since the water molecule in the material is ...
