Failure analysis and judgement of automatic weather stations

Automatic weather station is a scientific instrument to monitor changes in the meteorological environment, long-term work in the field environment, can achieve all-weather monitoring. The current meteorological monitoring system is gradually replacing the artificial monitoring in the country to promote the use of automatic weather station for its monitoring performance determines the quality of monitoring, automatic weather station operators need to maintain the normal operation of the equipment, stabilise the performance of the automatic weather station to ensure that the accuracy of the monitoring results, the automatic weather station inspection and maintenance has also become an important part of the work.

Failures of automatic weather stations are generally divided into two categories:

First, the accuracy of the monitoring results is reduced, for this type of fault checking starts from the meteorological sensors, and carry out sequential checking. This is a certain requirement for meteorological observers, requiring constant attention to meteorological monitoring in the monitoring of data changes in the meteorological elements, once abnormalities are found in a timely manner.

Secondly, the automatic weather station works abnormally. There are many reasons for this kind of failure, may be the power supply is not timely or low voltage caused by the computer serial port or collector failure or communication line failure. In the strong lightning environment may also cause the automatic weather station work abnormally. For automatic weather station managers should regularly monitor its operation to prevent the occurrence of failures and ensure the accuracy of the monitoring results.

For automatic weather station failure analysis and judgement, you can carry out the following steps:

Confirmation of fault phenomenon: Observe whether there is any abnormal phenomenon in the weather station, such as abnormal data acquisition, sensor failure, communication interruption and so on.

Check power supply: Ensure that the power supply of the weather station is normal, check whether the battery is sufficient, whether the power cord is well connected, and whether the power adapter works normally.

Check the communication connection: Check the communication connection between the weather station and the data receiving equipment, including the wireless signal strength, network connection, etc., to ensure that the communication is normal.

Check sensor status: Check the status of each sensor of the weather station one by one, including temperature, humidity, air pressure, wind speed, precipitation and other sensors, to ensure that they can collect data normally.

Check the data processing unit: If the weather station has a data processing unit, such as a computer or a microcontroller, check its operation status, including whether there is any deadlock, programme crash, etc.

Check data accuracy: Compare the data collected by the weather station with weather data from other reliable sources to judge the accuracy of the data. If the data is obviously abnormal, it may be caused by sensor failure or data processing unit failure.

Check environmental factors: Consider the impact of environmental factors on the weather station, such as bad weather, natural disasters, etc., which may lead to partial failure.

Seek professional repair: If the above steps cannot solve the fault, it is recommended to seek professional meteorological equipment repair services for further diagnosis and repair by professionals.

It should be noted that the above is only a general method of fault analysis and judgement, and the specific situation also needs to be judged according to the actual equipment and fault performance. When maintaining automatic weather stations, it is necessary to pay attention to the working status of the equipment at any time and carry out timely maintenance and repair to ensure the accuracy and reliability of meteorological data.
