Abstract

The invention discloses a wind speed and direction detection device, especially a wind speed and wind direction detection device based on piezoelectric effect, which includes an induction system and a measurement system. The induction system includes a vertical rod made of rubber material, a piezoelectric ceramic sheet, rotating device and wind receiving device, the piezoelectric ceramic sheet is 16 pieces, which are symmetrically and evenly attached to the outer wall between the top and bottom of the rubber vertical rod at the same horizontal height, and the rotating device is located on the rubber vertical rod At the top of the straight rod, the wind receiving device is connected to the rotating device through a nylon rope, and the two ends of the piezoelectric ceramic sheet are connected to the measurement system. The invention is installed on the top of the building, allowing the wind receiving device to swing with the wind, driving the piezoelectric ceramic sheet on the vertical rod to generate an output voltage, and then inputting the output voltage to the display circuit for display, and can measure the wind direction and wind speed at the same time, and With higher precision.

Description

technical field [0001] The invention relates to the field of wind speed and wind direction detection, in particular to a wind speed and wind direction detection device based on piezoelectric effect. Background technique [0002] One of the indispensable items in weather forecast is the wind force level and wind direction. In recent years, many types of wind speed or wind direction measuring devices have appeared, such as thermal anemometers with high precision, but the measurers need to measure outdoors; The rotary anemometer used in the weather station has the disadvantages of low accuracy, the measurer needs to read the anemometer, and the measurement of wind speed and wind direction cannot be concentrated together, which leads to the inconvenience of measurement; there are also shortcomings based on the Doppler effect and ultrasonic Good penetrability and strong directionality Applied for the patent of ultrasonic velocity measurement, such as the invention name: ultrasoni...
