Real-time synchronous measuring system for multiple factors such as wind-blown sand electric field, sand particle charging and wind speed

Abstract

A real-time synchronous measurement system for multiple factors such as a wind-blown sand electric field, sand particle electrification and wind speed, comprising: a first support, a second support, a third support, and an electric field instrument disposed vertically in parallel. A 3D ultrasonic anemometer (), a wind speed meter (), a temperature and humidity detector (), and a weather vane () are installed on and connected via data cables to the first support. A probe () of the electric field instrument is installed on the second support. A piezoelectric kinetic energy sensor () is installed on the third support. A data collector () is installed between and connected via data cables to the first support and the third support. A real-time sand particle mass-to-charge ratio instrument is further comprised. A computer () is installed between and connected via data cables to the second support and the real-time sand particle mass-to-charge ratio instrument. Through the combination of devices, comprehensive, synchronous, and frequent measurement of the wind-blown sand electric field, sand particle mass-to-charge ratio, sediment transport intensity and influences thereof such as the wind speed, wind direction, air temperature, and humidity is implemented. Therefore, the defects of the number of functions being small and poor synchronization in the prior art are overcome, so as to achieve the advantages of multiple functions and desirable synchronization.
