以PDA为终端的便携式农产品智能配送系统

Portable intelligent distribution system for agricultural product based on PDA

农产品配送是整个农产品供应链的重要环节,快速获取和精准管理农产品装货、运输、卸货过程中的信息及实现配送过程的有效监控是保证农产品物流配送过程中质量安全的重要措施。该文设计了便携式农产品配送系统的框架、功能及数据库,并根据系统数据的更新频率设计了不同的数据更新机制;在此基础上,着重探讨了基于RDA的数据同步开发和条码扫描装卸货实现流程;系统采用VS.NET开发平台在模拟器上实现了功能。由于便携式农产品配送系统运行需要GPS、GPRS/GSM、条码扫描等模块的支持,因此根据各模块的不同组合,制定3种系统运行测试载体方案,通过综合比较,PDA内置GPS和条码扫描模块、通过蓝牙接口连接GPS模块的方案在目前情况下比较适合农产品配送企业使用。

Agriculture product distribution is an important part of the whole supply chain.For ensuring quality safety of agriculture product in the process of distribution,it is most important to obtaining quickly and managing precisely the loading and unloading information and supervising effectively the distribution process.The framework,function and database of portable intelligent distribution system(PIDS)were designed and the data update mechanism was planed.The data synchronization development with RDA and implement steps of loading with barcode scanning were mainly discussed,The PIDS was implemented with vs.net.The operation of the PIDS requies supports of GPS、GPRS/GSM modules.Comparison with three different running schemes of PIDS on PDA,the one with the modules of GPRS,barcode scanning and the GPS module which was connected with blue booth interface is suitable for agriculture product distribution enterprises.
