Common faults and specific manifestations of automatic weather stations:

1. The sub station is not online: The yellow light on the customer terminal station used by the automatic weather station is a specific manifestation of this fault. The occurrence of this fault is generally caused by network or central station platform problems. Contacting the central station or conducting remote parameter testing is a common way to solve this fault.

2. Abnormal temperature value: As the temperature sensor of the automatic weather station is composed of a sensor wire and a PT100 platinum resistor, when there is an abnormal temperature value in the automatic weather station, we can solve the problem by checking whether the temperature sensor is damaged or if there is water ingress, and checking whether the circuit is virtual.

3. No rainfall or low rainfall: When there is no rainfall or low rainfall at the automatic weather station, the staff can determine the cause of this fault by checking for foreign objects in the cylinder cover, whether the rain gauge is blocked, and whether the reed switch is damaged.

4. Abnormal wind direction and speed: In order to better understand the fault of abnormal wind direction and speed in automatic weather stations, we need to measure the voltage value between the signal line and the ground wire, and determine whether the sensor is damaged based on the measurement results, in order to decide whether to damage the wind speed sensor.

5. There is a significant difference in the day and night data of the substation: For the fault of a significant difference in the day and night data of the substation, staff need to check the battery level and solar panels of the substation to ensure that the automatic weather station substation can complete its work well at night with sufficient power support.

6. Abnormal sensor data: For abnormal sensor data in automatic weather stations, staff need to check the collector motherboard and switches, and consider whether there is strong signal interference around the automatic weather station in order to solve the problem in a targeted manner.

7. Abnormal power supply system: For abnormal power supply system faults that occur in automatic weather stations, checking the battery voltage and solar panels, replacing the power control board, and replacing the acquisition board are the main solutions to this problem.
