Abstract:Meteorological data interprovincial sharing service provides the weather prediction and meteorological service of timely data for neighboring provinces. The National Meteorological Information Center now gets statistics and publishes the transmission quality of interprovincial sharing service by month. It is not easy to find out the abnormality during data transmission timely. We design and implement a real-time monitoring system for interprovincial data sharing service using the monitoring method for data upload transmission. Firstly, the system above decodes AWS-data and then shows the receiving and sending status of the hourly national and regional automatic station data and radar data. This system provides data application department and management department of the daily, monthly and annual statistics results based on SQL Server database and it also generates interprovincial sharing log files. The application result shows that the real-time monitoring system of meteorological data interprovincial sharing service is stable and reliable.
