Abstract

The invention relates to a moisture content detecting, controlling and monitoring system. The moisture content detecting system comprises a moisture meter system assembly, a lens assembly and a signal analysis assembly, wherein the moisture meter system assembly comprises a light source assembly, a terahertz radiator, a first terahertz detector and a second terahertz detector; the signal analysis assembly comprises a bias signal generator and a signal processing device; the light source assembly is used for generating a laser beat-frequency light beam and splitting the beam to the terahertz radiator, the first terahertz detector and the second terahertz detector; one part of a terahertz signal radiated by the terahertz radiator is returned to the first terahertz detector through the lens assembly, the other part of the terahertz signal is returned to the second terahertz detector through the lens assembly and a to-be-detected sample; and a reference electric signal obtained by the first terahertz detector and a sample electric signal obtained by the second terahertz detector are input into a signal processing device to carry out moisture content on the to-be-detected sample. With the adoption of the scheme, the moisture content detecting system can be used for carrying out moisture content detection accurately in real time, is relatively high in signal to noise ratio and is relatively high in stability.

Description

technical field [0001] The invention relates to the technical field of terahertz detection, in particular to a water content detection, control and monitoring system. Background technique [0002] In industrial production, moisture content is a key factor determining product quality. It not only affects the physical and chemical properties of the product, such as weight, density, viscosity, refractive index, water activity, electrical conductivity, etc., but also affects the processing performance of the product. Commercialization requirements, legality, etc. The moisture content detection system can not only control and analyze in industrial production, but also measure product quality. With the development of increasingly strict quality inspection, the detection of moisture content has become an important indicator to measure product quality, and has been widely used in medicine, Food, tobacco, paper, plastic, textile and other industries. [0003] The moisture content d...
