Abstract

The invention discloses a portable high-precision three-dimensional anemoscope, which consists of a compass positioning device, a three-path micro-electromechanical system (MEMS) gas flow chip, a constant flow source circuit, a multi-channel analog/digital (A/D) acquisition circuit, a temperature and humidity measuring module, a singlechip, a liquid crystal display module and a standard communication module, wherein the compass positioning device is arranged on the surface of the anemoscope and is used for indicating a direction in which an instrument is positioned; the three-path MEMS gas flow chip has a three-dimensional vertical structure and is fixed on the surface of the anemoscope; the constant flow source circuit is connected with the three-path MEMS gas flow chip and is used for providing accurate and stable current for the chip; output of the three-path MEMS gas flow chip is transmitted to the multi-channel A/D acquisition circuit; output of the multi-channel A/D acquisition circuit is transmitted to the singlechip; output of the temperature and humidity measuring module is transmitted to the singlechip; and output of the singlechip is connected to the liquid crystal display module and the standard communication module. The anemoscope has small volume and light weight, wide-range high-precision wind speed measurement is realized, and the manufacturing cost is greatly saved.

Description

technical field [0001] The invention relates to a portable high-precision three-dimensional wind measuring instrument, belonging to the technical field of automatic measuring instruments, which can be used to measure wind speed and wind direction data under various weather conditions and environments. Background technique [0002] (1) Background technology of anemometer [0003] The measurement of wind speed and wind direction is of great significance in various aspects such as meteorology, sports, and civil aviation safety. From this, various wind measuring instruments are derived, which are widely used in different occasions. [0004] At present, the common low-altitude wind instruments mainly include the following types: [0005] (1) Mechanical anemometers, such as wind cup anemometers, wind vane anemometers, etc. mechanical wind measurement [0006] The instrument rotates with the force of the natural wind through the movable blades, and measures the rotation speed to...
