Research And Development Of The Crop Tracebalility System Based On Gis

Food safety is important for human survival and development, disease prevention, improve human health guarantee. With the economic development and people’s living standards improve, the quality of the food safety proposed higher requirements, traceability of crop products, more and more attention. With the rapid development of computer science and geographic information science, geographic information system shows its powerful spatial analysis functions. GIS technology is used to establish the crop traceability system, visually display the crops from the production, processing, packaging and selling process all the information on the map, and consumers to improve the quality and safety of the crop products, crop products consumer confidence have far-reaching social significance. Crop traceability technology, has recently become a hot research in the field of quality and safety of agricultural products and focus on crop traceability system has been widely used in foreign countries. Traceability system and technical studies of crop products in China has just started in the research and implementation process, and gradually developed a number of related standards and guidelines establish a food traceability system is a key link of the food safety mechanism. In recent years, China’s endless stream of food safety issues in the community caused widespread concern, so as soon as possible to establish and improve the traceability system of agricultural products has a greater significance.The main function of the crop traceability system is to start from the growth of crops and management, including its growth process, the process of processing, packaging and storage processes and logistics, and sales process:the production process Log Origin soil conditions, crop fertilizers and pesticides usage; process record crop processing, product name, type, origin, the number of processing, packaging specifications and type, product code and other information; stored procedure to establish product storage warehouse and the environment, you can query system inventory information; logistics the process of GIS technology to achieve real-time tracking of the logistics process. Finally, enter the sales cycle, consumers can rely on the bar code on the outer packaging of agricultural products, by querying the terminal to check all the information in the crop products from the production, processing, packaging to the sales process. Crop traceability system can be recorded and stored crop products in the process of production, processing, packaging, distribution, sales and other related information on the terminal, and finally through the traceability code to query the crop product, retrospectively in the production, processing, packaging, circulation and marketing of all aspects related information.To now and finishing at home and abroad traceability system status, and summarizes the characteristics of the crop traceability system, combined with EAN.UCC coding system design suitable for crop characteristics Lot Code, and extracted through a proprietary encryption algorithm, Origin encoding and date of production, and finally the formation of traceability code, and then use the crop traceability bar code identification technology, data encryption technology, database technology, all aspects of crop distribution chain all the information for the entire record, and finally, the use of software engineering for crops the traceability data features, design crop traceability information database. Consumers or regulatory authorities through the Web terminal query, you can query to crop production, processing, distribution and transportation, and sales information. On the page output in the form of text the crop sales process through the city and related information, at the same time a rough itinerary and other relevant information can be displayed on the map.
