Abstract Regional automatic weather station has the characteristics of modularity,composing of multiple subsystem modules.And the power supply system plays a supporting role in the daily operation of regional automatic weather station.The faults of the power supply system can lead to abnormal weather data acquisition,which directly affect the prediction accuracy.The fault phenomena of power supply system are easy to confuse with other systems.The fault identification process is closely related to the communication system and the acquisition system.This paper analyzes the structures and operating principles of power supply system and also introduces the methods of identifying the fault according to an example,achieving the purpose of improving the accuracy and troubleshooting speed.
