Abstract

The invention discloses a wind speed and direction detection device, and particularly relates to a wind speed and direction detection device based on the piezoelectric effect. The wind speed and direction detection device comprises an induction system and a measuring system. The induction system comprises a vertical rod made of rubber materials, sixteen piezoelectric ceramic pieces, a rotating device and a wind receiving device. The piezoelectric ceramic piles are symmetrically attached to the portion, between the top end and the bottom end, of the outer wall of the rubber vertical rod on the same horizontal height. The rotating device is located at the top end of the rubber vertical rod. The wind receiving device is connected with the rotating device through a nylon rope. The two ends of each piezoelectric ceramic pile are connected with the measuring system. The wind speed and direction detection device is installed on the top of a building, the wind receiving device swings along with wind, the piezoelectric ceramic tiles on the vertical rod are driven to generate output voltage, the output voltage is input to a display circuit to be displayed out, the wind direction and speed can be detected at the same time, and the higher precision is achieved.

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...
