Real-time synchronous detection system for sandstorm flows

Abstract

The invention discloses a real-time synchronous detection system for sandstorm flows, which comprises a first support and a second support vertically arranged in parallel, a weighing sensor, a sand-gathering box and a wind direction guide plate are installed on the first support, an anemometer, a temperature and humidity detector, an anemoscope and a piezoelectric type kinetic energy sensor are installed on the second support, and a data acquisition instrument is arranged between the first support and the second support; the weighing sensor, the anemometer, the temperature and humidity detector, the anemoscope and the piezoelectric type kinetic energy sensor are respectively connected with the data acquisition instrument through data transmission lines. The real-time synchronous detection system for sandstorm flows can overcome the defects of fewer functions, poor synchronism and the like in the prior art so as to realize the advantages of more functions and good synchronism.

Description

technical field [0001] The invention relates to a wind-sand flow detection technology, in particular to a real-time and synchronous detection system of a wind-sand flow. Background technique [0002] In recent years, with the continuous deterioration of the natural environment, soil wind erosion has intensified, the expansion of desertified land has accelerated, and sandstorms have occurred frequently, which have caused serious environmental and social problems and caused huge economic losses. [0003] Wind-sand flow is the main form of wind-eroded sand movement in the near-surface layer of the atmosphere, and it is also an important reason for the formation of wind-sand disasters. In order to effectively curb the expansion of soil wind erosion and desertification, and reasonably formulate corresponding sand prevention and control projects and measures, it is necessary to use instruments and equipment to carry out quantitative and long-term positioning observations of near-s...

Problems solved by technology

[0004] At present, the instruments used for field observation of wind and sand can only realize asynchronous low-frequency measurement of a certain amount (such as sand transport) or a few quantities, and there is still a lack of wind and sand flow, especially the wind and sand flow and its influencing factors under unattended conditions in the field The all-round synchronous real-time high-frequency dynamic measurement cannot reveal the law of wind and sand movement in depth

[0005] It can be seen that in the process of realizing the present invention, the inventor has found that there are at least defects such as few functions and poor synchronization in the prior art.
