Device and method for extracting physical parameters of special environment based on resonant frequency test

Abstract

The invention discloses a device and a method for extracting physical parameters of a special environment on the basis of resonance frequency tests. The device comprises a transmitting unit and a receiving unit. The transmitting unit is located in the special environment, and the receiving unit is located in a conventional environment; the transmitting unit is communicated with the receiving unit via a transmitting antenna and a receiving antenna; a passive microwave resonance structure is arranged inside the transmitting unit in the special environment; the receiving unit at the normal temperature under the normal pressure is far away from the special environment. The device and the method have the advantages that the passive microwave resonance structure which is sensitive to the physical parameters is arranged in the measured environment, resonance frequencies of the resonance structure can correspondingly drift under the condition of indexes of the different physical parameters, frequency drift of the microwave resonance structure can be detected, and accordingly the physical parameters can be tested in the special environment by the aid of relations between the resonance frequencies and the physical parameters.

Description

technical field [0001] The invention relates to a special environmental physical parameter extraction device and method based on resonance frequency testing. Background technique [0002] With the rapid development of the domestic equipment manufacturing industry, the processing, preparation and testing of many special equipment or special materials need to be completed in special environments (such as high temperature, high pressure, etc.), and some key components have been in special environments for a long time, requiring real-time and accurate The physical parameter data of the special environment in which it is monitored. The acquisition of physical parameters in these special environments plays a vital role in the improvement of the equipment manufacturing process level and product technical indicators. However, due to the limitations of special environments, the acquisition methods of these physical parameters cannot be directly completed. can be obtained indirectly ...

AI Technical Summary

Problems solved by technology

[0006] Existing physical parameter extraction methods cannot be applied to physical parameter testing under certain special environments (such as high temperature, high pressure, etc.), for example, there is no effective pressure in-situ test method for over 300°C, and there is no long-term in-situ temperature parameter over 1000°C Testing methods currently mainly rely on indirect testing methods such as extrapolation and pressure induction, which have problems such as inaccurate results and insufficient dynamic response, and cannot realize real-time detection and control of physical parameters in special environments

Physical parameter testing technology in special environments has become a "bottleneck" restricting equipment performance improvement
