摘要
黑河流域生态水文WSN观测数据自动综汇系统于2012年7月正式发布。随着数据申请人数骤增,之前采用的权限管理模式、下载流程已经无法满足需求。针对黑河流域自动观测数据共享应用过程中的具体需求,将黑河计划数据管理中心下载系统与黑河流域生态水文WSN观测数据自动综汇下载系统进行对接,对下载系统的权限粒度、授权方式、数据生成及获取方式进行优化改进,极大地提高了数据共享效率,对于自动观测数据的在线共享具有重要意义。
Data automatic assembling system for a wireless sensor network in Heihe Watershed Allied Telemetry Experimental Research was released officially in July 2012.With the surge of the number of data applicants,accessing control mode and the download process adopted before which has been unable to meet users＇ demand.In response to the users＇ need in sharing application of Automatic Data in Heihe River Basin,this paper combines downloading system in Heihe plan data management center with downloading system in Automatic Assembling System for a wireless sensor network in Heihe Watershed Allied Telemetry Experimental Research to improve access granularity,authorization,data generation and acquisition mode,which greatly improves the efficiency of data sharing which is significant for automatic observation data for online sharing.
