.Antenna sensor-based liquids identification and wireless monitoring system

摘要

Antenna sensor based liquid identification and wireless monitoring systems are introduced. To this end, the present invention provides a radio communication system including a radio wave generator for generating radio waves having a predetermined frequency range; A sensor unit for irradiating the measurement object with the radio wave generated by the radio wave generator and detecting a radio wave reflected by the measurement object; An analysis unit for measuring a resonance frequency of a radio wave detected by the sensor unit; And a control unit for controlling the radio wave generating unit to determine the frequency of the radio wave and collecting and transmitting data analyzed by the analyzing unit. Wherein the sensor unit is an antenna sensor including a pair of measurement objects sandwiched therebetween, wherein the sensor unit comprises: a resonator forming a mode of the wave generated by the wave generator; An antenna for radiating a mode of a radio wave formed by the antenna to the measurement object and receiving a radio wave reflected from the measurement object, and an antenna for irradiating the radio wave radiated through the antenna with the measurement object and collecting a radio wave reflected from the measurement object Wherein the analyzing unit measures the resonance frequency of the radio wave detected by the sensor unit and the analyzing unit measures the change amount of the reflectance in addition to the resonance frequency of the radio wave detected by the sensor unit , The measured resonance frequency of the radio wave and the change amount of the reflectance measured from the measurement object The degree of contamination of the water when the liquid is water or the degree of the salt content of the seawater when the liquid is seawater is measured based on the change amount of the resonance frequency and the reflectance of the measured radio wave .
