Abstract

The invention discloses a suspended three-dimensional wind speed and direction sensor structure. A central wind induction device is adopted, and a bottom elastic structure is driven to be correspondingly strained with wind speed and direction, so that a strain sensor fitting the elastic structure is deformed to generate an output. The suspended three-dimensional wind speed and direction sensor structure provided by the invention is simple in principle, can be used for monitoring three-dimensional wind speed and direction, and is convenient to mount, low in cost, low in temperature drift and suitable for the needs of portable and mobile measurement.

Description

technical field [0001] The invention relates to a wind speed and direction detection device, in particular to a pendant type three-dimensional wind speed and direction sensor structure. Background technique [0002] Wind speed and wind direction are very important parameters to reflect meteorological conditions, and have an important impact on environmental monitoring, air conditioning, and industrial and agricultural production. Therefore, it is of great practical significance to quickly and accurately measure wind speed and wind direction. Traditional wind cups and wind vanes are still widely used detection devices, but these mechanical devices are easy to wear due to moving parts, and at the same time have the disadvantages of large size, high price, and frequent maintenance. A typical ultrasonic wind speed sensor has a fixed position of the transmitting and detecting receiving heads, so the relative structure is also relatively large. The miniature thermal velocity sens...
