摘　　要：文章针对安徽省加密自动气象观测站数据传输过程中存在的问题,完成全省加密自动气象观测站数据传输环境改造,包括4G及物联卡的应用、数据格式的统一、数据传输与报文转发流程优化以及双路通信热备机制的实现。截至2019年,全省加密气象观测站在新的数据传输环境中已稳定运行半年,相较于改造前,加密气象观测站数据报文收集平均延迟时间从40 s降低为10 s,生成及上传国家局统一格式文件的平均延迟时间从120 s降低为20 s。数据传输环境改造极大地提高了加密气象观测站数据传输效率。Aiming at the problems existing in the data transmission process of the encrypted automatic weather observation station in Anhui province,this paper reconstructs the data transmission environment of encrypted automatic weather observation station in the whole province,which includes the application of 4G and IOT cards,the unification of data format,the optimization of data transmission,message forwarding process and the realization of dual-channel communication hot standby mechanism.By 2019,the provincial encrypted meteorological observation stations have been operating stably for half a year in the new data transmission environment.Compared with the renovation before,the average delay of data message collection of the encrypted meteorological station was reduced from 40 seconds to 10 seconds,and the average delay time of generating and uploading files in the unified format of the national administration was reduced from 120 seconds to 20 seconds.The reconstruction of the data transmission environment has significantly improved the data transmission efficiency of the encrypted weather station.
