摘　　要：介绍了一起典型的由于民航气象数据库通信分系统的配置文件格式错误而导致的气象数据库资料传输故障案例,采用排除法对通信系统资料传输故障进行详细分析,逐个排除,最终确定故障点为.netrc配置文件格式错误,并给出详细的处理过程。探讨了此次故障原因以及暴露出的问题,从熟练掌握通信系统的系统配置文件的内容及用途、升级改造气象数据库系统、增加日常维护经验等三个方面提出了防范整改措施,以帮助气象数据库运行维护人员对此类故障的准确排查。A case of data transformation interruptioncaused by an error modifying configuration file has been introduced. The elimination methodis used in the detailed analysis of data transmission trouble caused by communication system. The analysis has been carried on by removing method, thefault point is determined and eliminated. The exposed problems have been discussed.The measures of prevention have been proposed frommasking configuration file of communication subsystem,upgrading the civil aviation meteorological database systemand increasingdaily maintenance experience. It can provide the directive function to operation and maintenance staffs.
