Portable intelligent distribution system for agricultural product based on PDA

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.
