Abstract:
The structure design, data flow frame, characteristic and founction of themeteorologywarning and commanding service system forLanzhou railway flood preventionwas inrtroduced in this paper. By using network technology, the system provided a highly effective, high quality and prompt service platform for the Lanzhou Railroad Bureau. The system provides the real-timemeteorological data, 72 hours fine prediction, three times line prediction in a day, mid-rangeweather forecast and the flood disaster information as well as jurisdictionalboundary chartalong the route. Moreover, based on statistics ofall flood disaster information provided byLanzhou Railroad Bureau andmeteorological data during the period of2002-2007, the temporal and spatial distribution of flood dasster along the railway route has been obtained, and the flood disaster features under the different type andmagnitude ofprecipitationwas also obtained and five gradeswarning ranks have been established, the railway line flood disasterwarning signal is issued for 15 routes, respectively.
Key words: railroad flood prevention, meteorologicalwarning, flood characteristic, flood disaster database
摘要:
介绍了兰州铁路防洪指挥气象预警服务系统的结构设计、数据流程、系统特点、功能研究成果。该系统利用网络技术,为兰州铁路局防洪指挥提供高效、优质、及时的服务平台。系统提供实时气象资料查询72 h站点精细化预报、每日3次线路预报、中期预报及沿线管界图、灾害库等资料信息。另外,统计分析了2002~2007年历年兰州铁路局水害的详细资料及气象资料后,分别给出了铁路沿线的水害时空分布特征及不同降水类型、量级影响下发生水害的特征,建立了5级预警等级,并以此为基础分别为15段铁路线路发布铁路水害预报预警信号。
