Embodiment Construction

[0033] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0034] Electrical tomography is a process parameter measurement technology developed in recent years, which is widely used in medical, chemical, energy and other fields. Compared with traditional measurement methods, electrical tomography technology has the ability to reconstruct the spatial distribution of substances in the measured area under the condition of non-invasion of the measured medium, so as to obtain more abundant flow information and provide information for the reaction process or flow process. complete information.

[0035] Electrical tomography sensors include electrical capacitance (Electrical Capacitance Tomography-ECT), electrical resistance (Electrical Resistance Tomography-ERT), electrical impedan...

Abstract

The invention provides a multi-mode sensor. The multi-mode sensor comprises a plurality of signal fusion acquisition assemblies, the plurality of signal fusion acquisition assemblies are used for being distributed at the same cross section height of an enclosure wall of a detected fluid area in a circumferential array mode, and the plurality of signal fusion acquisition assemblies are used for acquiring microwave signals, capacitance signals and resistance signals of the detected fluid area, carrying out fusion imaging on the microwave signal, the capacitance signal and the resistance signal to obtain a feature distribution image of the detected fluid region; wherein each signal fusion acquisition assembly comprises a microwave/capacitance signal acquisition unit used for acquiring a microwave signal and a capacitance signal of a detected fluid area in a crossed manner; and the resistance signal acquisition unit is used for acquiring a resistance signal of the detected fluid area. According to the invention, the multi-mode sensor composed of a plurality of signal fusion acquisition assemblies is utilized, so that the flow information of the detected fluid region is obtained, and complete information can be provided for a reaction process or a flow process.

Description

technical field [0001] The present disclosure relates to the field of measurement technology and sensor technology, and in particular to a multi-mode sensor. Background technique [0002] In industrial processes, effective real-time monitoring is crucial for process control and optimization of wet particle gas-solid flow or oil-gas-water multiphase mixed transportation in pipelines or reactors. Commonly used single-point measurement obtains limited flow information and destroys the flow field, which cannot provide complete information for the reaction process or flow process. Contents of the invention [0003] In view of the above technical problems, the present disclosure provides a multi-modal sensor in order to at least partly solve the above technical problems. [0004] A multimodal sensor comprising: [0005] A plurality of signal fusion acquisition components, wherein the plurality of signal fusion acquisition components are used to be distributed in a circumferent...
