Three-dimensional probe and intelligent sandstorm electric field measuring system based thereon

Abstract

The invention discloses a three-dimensional probe and an intelligent sandstorm electric field measuring system based thereon. The system comprises the three-dimensional probe, a front-end processing unit and a rear-end processing unit. The three-dimensional probe contacts with a sandstorm electric field and is used for acquiring an X-directional field signal, a Y-directional field signal and a Z-directional field signal in the electric field. The front-end processing unit is connected with an X-directional signal acquisition end, a Y-directional signal acquisition end and a Z-directional signal acquisition end respectively and is used for performing primary processing to the field signals in the corresponding directions, which come from the three-dimensional probe. The rear-end processing unit is connected with the front-end processing unit and is used for selecting and comprehensively processing primary processing results respectively. The defects of poor sandstorm resistance, no ability to interference resistance, low intelligence degree and the like in the prior art can be overcome, so that the three-dimensional probe and the intelligent sandstorm electric field measuring system based on the three-dimensional probe have the advantages that sandstorm resistance is high, a lateral electric field can be shielded, measuring range is wide, and intelligence degree is high.

Description

technical field [0001] The invention relates to the technical field of wind-sand electric field measurement equipment, in particular to an intelligent wind-sand electric field measurement system based on a three-dimensional probe and a three-dimensional probe. Background technique [0002] The wind-sand electric field refers to an electric field that is 2-3 orders of magnitude higher than the atmospheric electric field in sunny days due to the movement of sand particles (dust) with a certain amount of charge in the wind-sand environment, which directly affects the formation and development of the wind-sand flow process, changes in sand transport intensity, and normal transmission and reception of communication radar signals. How to accurately and real-time measure the wind-sand electric field in different wind-sand environments (sand flow, sandstorm and dust volume) has become a hot issue in the field of environmental mechanics research. [0003] At present, there are two m...

AI Technical Summary

Problems solved by technology

[0004] (1) Sand particles of different particle sizes and shapes mixed in the sandstorm environment will impact the vibration and rotation sensing parts at the front end of the electric field measuring equipment probe during the measurement process. As a result, the sensing parts of the probe cannot work stably and affect the experimental results. correctness and precision;

[0005] (2) The linearity of the existing atmospheric electric field measurement equipment is good, and the working range of the more sensitive response is mainly within 100kV / m. In the windy and sandy environment, especially in the sandstorm, the electric field of 200kV / m-300kV / m has been found. Therefore, the existing atmospheric electric field measurement equipment cannot meet the measurement of the electric field in the wind and sand environment from the perspective of range;

[0006] (3) Due to the complex environment and conditions of the sandstorm electric field, the direction of the electric field is not certain, and its direction and size in the three-dimensional space are constantly changing, and the existing atmospheric electric field measurement equipment does not have the ability to measure the three-dimensional electric field. Therefore, the three-dimensional distribution results of the wind-sand electric field cannot be completely given

In the process of realizing the present invention, the inventor found that there are at least some defects in the prior art, such as poor anti-wind and sand ability, lack of anti-interference ability and low degree of intelligence.
