Non-contact temperature measurement and material component detection device and method based on magnetic conductivity

Abstract

The invention discloses a non-contact temperature measurement and material component detection device and method based on magnetic conductivity and aims to realize non-contact temperature measurement and material component detection. The non-contact temperature measurement and material component detection device based on magnetic conductivity comprises an alternating current power supply, an excitation coil, a detection coil, a high-pass filtering module, a weak signal detection module and a computer. The detection method comprises the following steps of: installing equipment and setting power supply parameters; carrying out experimental calibration on the relationship between material magnetic conductivity, temperature and material components; establishing a correlation curve and deducing a correlation fitting function; and finally outputting detection data by adopting a computer so as to realize the measurement of the temperature and the components of a material. The other method is characterized in that a database and a deep learning model are constructed by using a deep learning method after experimental calibration. According to the detection device and method provided by the invention, non-contact temperature measurement and material component detection can be realized without being influenced by a complex environment in a container and without interfering the characteristics of the material.

Description

technical field [0001] The invention belongs to the field of temperature measurement and the technical field of material composition detection, and in particular relates to a non-contact temperature measurement and material composition detection device and method based on magnetic permeability. Background technique [0002] The traditional temperature measurement method is mainly contact temperature measurement, such as thermocouple and thermal resistance temperature measurement. After years of research and development, the contact temperature measurement method has developed relatively mature and has been widely used in industry. However, the contact temperature measurement is directly in close contact with the measured object. In a high-temperature working environment, the measurement device is prone to aging and damage, resulting in inaccurate temperature measurement results. [0003] The non-contact temperature measurement method does not need to be in contact with the m...

Problems solved by technology

[0006] At present, there is no relevant research on the methods and instruments for detecting the magnetic permeability of materials in the rotary kiln for direct reduction. Most of the detection of magnetic permeability is carried out on metals, the distance is relatively short, and the device is small. Although the accuracy is high, but There are few studies on non-contact temperature measurement and material composition detection using magnetic permeability.
