Logistics Information System For Agricultural Products Based RFID And PPC

According to the logistics chain of agricultural products, the establishment of agricultural products from produce to sales information backward,and the realization the logistics chain for agricultural products tracking of all aspects of the logistics system of agricultural products is the main problem to be resolved. This design of agricultural logistics information management system related to agricultural produces link, process link, circulate link and market links, Gathering each link's characteristic information, and compiling to the data central. Agricultural logistics chain reaction of feature information besides the general character, also need to highlight the special nature. Through the agricultural logistics information management system, and make every step of the process of agricultural products to coordinate, effectively improve the efficiency of the logistics of agricultural products.The handset hardware uses RFID reader SDiD1020 by SDIO, designed software runs on Windows Mobile phones, so mobile devices have good portability .The label uses ISO14443 standard S50 chip tags. As the S50 chip capacity constrains, and need to store different information in various stages, therefore the software has limited the character integer of the label write information. The software designs the Chinese interactive interface, use Chinese formatted record information. The label support Chinese characters reading and writing. The help information assists to instruct the operation of software. Chinese interactive interface and handwrite input interface are suitable for all stages of logistics.Mobile terminal save the data of reading. Through the wireless communications and wired data transmission combination, operators can any choose means of transmission by indoor or outdoor environment, so operators can operate in scene or long-distance transmission. Software support Bluetooth transfer date in LAN, also supports remote data transmission via GPRS, and can use the smart phone's data cable and ActiveSync synchronization software upload information text to the server.Logistics information in a timely manner all updates and releases, the monitoring center to collect all kinds of agricultural products of the time, place and other details to manage, deploy, track and trace on agricultural products. The site operators send the data instantly to the server, the remote operator update data and manage the database through by the agricultural products logistics information system software. This selects relationship database ACCESS and background data management system ASP.NET to realize the agricultural products logistics information system data management on server-side. The system sends data to the server by data transmission module, and integrated manage. The server-side software receive date from the mobile devices, and add, delete, insert, update data , add notes, publish web and support users query and search through a web. After login system page, users can retrieve the product number of agricultural products for more information.
