Problems solved by technology

The microwave resonator method usually only reflects the moisture content of the material near the resonator, and cannot reflect the average moisture content of the material as a whole. In addition, it is necessary to ensure that the material and the resonator have a specific relative positional relationship to ensure the accuracy of the test. For example, during the test process, the material surface and The test surface of the resonant cavity needs to be kept in close contact at all times, which has high requirements on the shape of the material, the size of the sample, the state of motion and the installation position of the equipment, and is subject to more restrictions in practical applications

Abstract

The invention discloses a testing method of a radar type microwave water measuring instrument, comprising the following components: a frame base: used for placing a material sample to be measured; a microwave radar host: used to transmit a continuous single-frequency microwave signal to transmit the material sample to be measured; And receive the beacon signal emitted by the beacon, and send the output data to the data processing terminal; signal, and transmit the beacon signal to the microwave radar host; data processing terminal: the data processing terminal outputs a frequency selection signal to the microwave radar host, and the microwave radar host outputs a continuous single-frequency microwave signal of the corresponding frequency according to the frequency selection signal, and the data processing terminal also It is used to receive the output data of the microwave radar host and calculate the moisture content of the material to be tested.

Description

technical field [0001] The invention relates to a water measuring device, which is a radar-type microwave water measuring instrument widely used in industries such as industry, agriculture, and medical treatment, and is used to measure the moisture content of materials (the percentage of water weight in materials and the total weight of materials) Fast, non-contact, accurate online measurement. Background technique [0002] In industries such as industry, agriculture, and medical care, the moisture content of materials such as building materials, crops, grains, textiles, and medical raw materials needs to be accurately measured and controlled in order to better control product quality. At present, the commonly used methods for measuring the moisture content of materials include heating and drying weighing method, infrared reflectance water measurement method, microwave resonant cavity method, microwave transmission method and so on. The heating and drying weighing method is...
