The wind direction wind speed recorder is developed using the wind direction wind speed sensor. During the operation, the sensor may have some faults. The following is the analysis of the fault cause of the wind direction anemometer sensor:
(1) Wind speed sensor: the rotation is inflexible and stuck; the wind speed is 0m/s; the wind speed indication has obvious deviation from the electric wind speed indication value; the starting wind speed is obviously high; the low wind speed is normal, the wind speed is large The time is not normal or obviously low. In the case of the above situation, the analysis can be performed. The wind speed sensor is measured electrically. If there is a fault, replace the sensor; if there is a stuck phenomenon, disassemble the sensor for maintenance cleaning or replace the sensor; the wind speed is 0m/s, check the cable and There is no problem with the power supply system. Use the backup equipment to connect and turn the wind speed axis. If the shaft turns flexible and there is no obvious noise, it means that the rotating part of the wind speed sensor works normally, check whether there is data in the indication value, and if there is data, check whether other parts work normally. If there is no data, the wind speed sensor is faulty, replace the sensor; use a multimeter to detect the frequency change between the FS and the ground in the outdoor signal transfer box, if there is no sensor fault; use the wind direction wind speed calibrator to check whether the wind direction sensor works normal.
(2) Wind direction sensor: the wind direction indicator is inflexible and stuck; the wind direction is 239°; the wind direction is 0°; the wind direction indicator and the electric wind direction indicate obvious deviation; the wind direction is different. Incorrect; the wind vane turns but the wind direction does not change. Charge the wind direction sensor, if there is any fault, replace the sensor; find the stuck phenomenon, replace the sensor or disassemble the sensor for maintenance cleaning; if it is 239 °, the signal is open, check the connector and cable; the wind direction is 0 ° check Cable and power supply system; use the backup equipment to connect, turn the wind vane, if it can rotate to make the wind direction value 239°, it means the wind direction sensor works normally, check whether other parts work normally; use the backup equipment to connect, turn the wind vane, always The wind direction indication value does not appear 239°, and the other directions also often show a jump display, indicating that there are some infrared light-emitting diodes in the wind direction sensor are bad, check and repair; use the wind direction wind speed calibrator to check whether the wind direction sensor works normally.
Through the above method, the wind direction wind speed recorder is analyzed for the failure of the wind direction wind speed sensor. Through the fault analysis, the best method is adopted to solve the problem, and the wind direction anemometer can timely and accurately monitor the wind direction wind speed change during the monitoring process.
