Agricultural weather station wind speed data abnormal processing way

Reasons for abnormal data: Wind speed data problems are generally the cause of the poly-carbon wind speed sensor, poly-carbon wind speed sensor using mechanical structure design, there are rotating parts, so there is a minimum wind speed before monitoring as a start condition, if the wind speed is lower than the start value will not be able to drive the propeller or wind cup for rotation, it will not be able to monitor, so in the daily wind speed is slow in the region, the wind speed may be zero.

Wind speed data anomaly handling method.

1, poly-carbon wind speed and direction sensor because of the mechanical structure will inevitably deviate, in the use of poly-carbon wind speed and direction sensor, be sure to examine whether the local wind speed is in the minimum wind speed below the time, try to apply in the windy scenes to reduce the error. In addition, regular cleaning of the poly-carbon wind speed sensor to prevent dust in to increase the friction coefficient.

2, choose to install ultrasonic type wind speed wind sensor, ultrasonic sensor advantage is: ultrasonic detection wind speed without starting wind speed, even zero wind speed conditions can work, and different from the mechanical wind speed wind direction need two devices, ultrasonic set two wind speed, wind direction two monitoring methods as one, while detecting, while output.
