CC天气雷达数据流传输业务台站级监控报警系统的设计与实现

Design and Implementation of Monitoring and Alarm System for Data Stream Transmission of CC Weather Radar

利用UDP组播通信、进程监控、文件监控、网络监控等技术,研发了CC天气雷达数据流传输业务台站级监控报警系统,较早、较好地实现了雷达扫描状态、数据流上行传输、标准格式基数据本地存储、基数据补传、软件运行和网络运行状态的实时监控和短信报警。实践表明,软件运行较稳定,能对数据流传输业务进行有效监控,短信报警准确及时,报警阈值从6min缩短到40s,提升了故障的发现和处理效率,提高了天气雷达业务可用性和数据传输质量,减轻了雷达台站业务人员的值守压力。

Using the UDP multicast communication,process monitoring,file monitoring,network monitoring and other technologies,the station-level monitoring and alarm system for CC weather radar data stream transmission service is developed.The real-time monitoring and short message alarm of radar scanning status,data stream upstream transmission,standard format base data local storage,base data replenishment,software operation and network operation status are implemented.Practice shows that the software runs stably,can effectively monitor the data flow transmission,and the short message alarm is accurate and timely.The alarm threshold is reduced from 6 minutes to 40 seconds,which improves the efficiency of fault detection and processing,the operational availability of weather radar,and the quality of data transmission,and reduced the duty pressure of radar station operators.
