摘　　要：选取了气象信息网络运行维护保障中出现频率较高,故障现象较典型的个例进行分析。针对不同的个例分别总结了具体的诊断处理流程和相应故障排查方法。在气象上行报文传输故障个例和防火墙设备故障导致数据接收异常个例诊断分析中采用"排除法",能够快速缩小故障范围定位到故障发生点;按照网络拓扑图形的路由走向采用了"分段检测方法"可以迅速追踪定位到通信网络故障造成的报文传输异常个例的故障源;在气象下行报文传输故障个例中如果根据气象数据下行广播流程采用逆向顺序反查故障原因可以快速找到异常原因。An analysis is made of some typical cases selected from the faults encountered in the operational maintenance of the meteorological information system.The corresponding countermeasures are presented.In the case of failure in uplink packet transmission and firewall equipments resulting in abnormal data reception,the exclusion method is adopted,with which the scope of failure can be narrowed quickly,so to locate failure points,and according to the routing trend of the network topological graph,the method of segmental check is used to quickly track the location of packet transmission failure caused by abnormal communication network.In the case of downlink packet transmission failure,the causes can be found quickly by means of the method of reverse direction,according to the flow of meteorological data downlink broadcast.
