| In recent years,the agricultural products quality and safety incidents occur frequently in our country,so that the problem of the quality and safety of agricultural products has become the focus in all kinds of industry.A new type of agriculture modernization development mode called Community Support Agriculture,CSA for short,was introduced to China as an exotic,which is considered to be a feasible method for the solution of the problem of the quality and safety of agricultural products.However,This kind of CSA model is restrcted to a certain extent for the lack of an external physical mechanism to protect its credibility which depends on the trust of the characteristics of the consumer groups and experience.Focusing on these issues,this study develops the vegetables quality safety traceability system based on CSA model combining with the actual demand of Guangzhou SanFenDi agricultural science and technology company,taking the vegetable industry as a starting point.The paper puts forward the CSA traceability system model on the basis of the design method in general CSA model,combined with the features of CSA model“from farm to consumer”.It adopts the software engineering design method and the PHP+MySQL development environment for system development to design the logical framework,system structure,function module and data model of the vegetable quality safety traceability system based on CSA model.And it uses the Object oriented programming to realize the system in the development stage.The main feature of the system includes: closely linked to the CSA operation mode,combining the actual demand of the enterprises,mobile devices to entry and retrieve the traceability data,adopting the application of two-dimensional code to enhancing the users' experience.After the realization of the system,it is applied in the platform of Guangzhou SanFenDi agricultural science and technology company,and achieves obvious social benefit and economic benefit. |
