The Design And Application Of Vegetable Quality Security Trace System Based On Things Of Internet

Food quality security traceability is an effective method to ensure the food safety,which attracting an increasingly attention at home and abroad.Henan Province is a major agricultural province in China and the vegetable production base,however,the development of vegetables quality trace technology is still in the start-up phase.Several issues are remained,e.g.,the inaccurate of history material,the problem of quick achievement of vegetables quality information,the incomprehensive management of vegetables security information etc.In this paper,we integrate the key technology of agriculture network and devices of food quality traceability,developing a system of vegetable quality security traceability which adapting to the agriculture-related enterprises and specialized cooperatives based on the technology of Things of Internet,the key technology of vegetable quality trace in our country and facilities.Firstly,we finish the demand analysis with the manager in vegetable cooperatives and design the system overview that consists of transaction flow diagram(TFD)and system structures.Then we accomplish the detail design of cases and database by considering the application of Things of Internet in the trace system.Finally,we complete the encoding based on the Visual Studio platform and SQL Server 2008 database.Our system is security and reliable by testing.The system consists of vegetable base management subsystem,transmission management subsystem,vegetable sales subsystem and vegetable trace subsystem.Through the system,we realize the accurate of history material,the quick achievement of vegetables quality information,the comprehensive management of vegetables security information and the vegetable quality supervision.Achieving the all-around and multi-angle supervision in the process of the inputs utilization,key product parts and the circulation,forming the circulation file,realizing the efficient trace of vegetable quality.
