The distribution of meteorological service data is an important part of the public meteorological service. The PMSDDS V1.0 (Public Meteorological Service Data Distribution Software Version 1.0) is a set of operational meteorological service data distribution system, which carries on the secondary application development to the open source transmission component libcurl, and transfers weather service data based on FTP. The software has the characteristics of the exactmatching and fuzzymatching file names that conforms to the public meteorological service product naming specification, multiparameter control, logs and so on, which effectively solved the problems of the distributed deployment of data transmission service, the tight coupling of other processes, the repeated development, and lack of logs, etc., as well as common data transmission problems such as leakage, congestion, waiting, etc. The application shows that the software is stable and the success rate of transmission is above 99.97%. Since the software runs online, the data transmission service has been deployed and monitored uniformly. According to the statistics of operational and maintenance departments, the annual deployment of transmission service increased by 50 times compared with the previous year, and the failure rate of operation and maintenance caused by transmission problems decreased by about one third year on year, which greatly improved the service efficiency.
