Field air velocity detection system

Abstract

The invention discloses a field air velocity detection system which comprises a base, a protection cavity with an upward opening is formed in the base, an unfolding device capable of stretching and retracting an object is arranged in the protection cavity, a protection cover is arranged above the base, and a matching cavity with a downward opening and capable of being matched with the protection cavity is formed in the bottom wall of the protection cover. A detection device capable of detecting the air velocity and the ambient environment is arranged between the matching cavity and the solar panel unfolding device; the air environment measuring module can detect other useful parameters such as temperature, humidity, oxygen content and the like in the air, can also detect smoke, is provided with a camera, can monitor the outdoor environment condition at any time, and in case of extreme weather outside, through the inspection of the air environment measurement module and the analysis of the power supply, a protection action is automatically performed, so that the precise measurement instrument is prevented from being damaged.

Description

technical field [0001] The invention relates to the field of flow rate sensors, in particular to a field air flow rate detection system. Background technique [0002] The detection of conventional gas flow velocity adopts the principles of differential pressure, turbine, electromagnetic, ultrasonic, etc., and the measurement of flow velocity in the prior art generally adopts the principle that the rotatable impeller is placed in the fluid, and the rotation angle of the impeller is proportional to the velocity of the fluid. To measure the flow velocity, this measurement method essentially uses the force generated when the fluid flows to push the impeller to rotate and then measure; [0003] The current flow rate measuring instruments only have a single function of measuring wind speed, and they are all exposed to the outside. Without effective protection, they are easily damaged by the outside world. The battery life is also limited by the power supply capacity. Manual replac...

[0003] The current flow rate measuring instruments only have a single function of measuring wind speed, and they are all exposed to the outside. Without effective protection, they are easily damaged by the outside world. The battery life is also limited by the power supply capacity. Manual replacement is often required to increase the work intensity of workers.
