Design And Implementation Of Agricultural Product Safety And Quality Traceability System

With the improvement of modern living standards,people's requirements for the quality of life are getting higher and higher.The issue of quality and safety of agricultural products has caused a great degree of public panic after exposure by the media.The social impact is very bad.Therefore,strengthening the construction of traceability system of agricultural products and promoting the development of traceability platform of agricultural products are the primary tasks at present.Since2002,China began to develop the traceability system of agricultural products and develop a traceability platform with perfect functions.It can not only ensure that new agricultural products can be effectively monitored and prevented from quality and safety problems when they are circulated in all links of the supply chain,but also recall the agricultural products with safety accidents in time to deal with them,so as to avoid their influx into the market affecting consumers' health and causing economic problems to production enterprises.Or loss of reputation.At present,there are two main problems in the traceability system of agricultural product quality and safety in our country.One is the imperfect business function of the system,which can not guarantee the authenticity and integrity of traceability information.The other is that the security and anti-counterfeiting of the system need to be improved.This paper combines the development status of traceability system at home and abroad and the actual situation of domestic production enterprises,designs a traceability system with complete business function modules,and isolates the console portal of each link leader to ensure that each link leader can only operate related to this link,and then adds encryption module on this basis to improve system security and anti-counterfeiting traceability.Sex.For business function modules,relevant responsible persons and data acquisition points are set up in the traceability links of production,processing,warehousing,logistics and sales respectively,and traceability codes are designed according to international coding standards at traceability nodes.The data are automatically collected by radio frequency technology and bar code technology,and the key nodes are connected in series to form a complete traceability chain,so as to achieve complete traceability.Traceability information.For the encryption module,its main purpose is to improve system security and anti-counterfeiting traceability,to ensure the authenticity of product information.The module includes two sub-modules: traceability code encryption and user password encryption.The former implements anti-counterfeiting function by encryptingtraceability code based on Rijndael algorithm,and the latter ensures user information security by encrypting user registration password based on MD5 algorithm.The main B/S structure is adopted in the development of the traceability system for agricultural product quality and safety in this paper,which combines system development technology,bar code technology and encryption technology to realize convenient and real-time data interaction and ensure the authenticity and validity of information.The system can not only let consumers know the detailed production process of products,but also let enterprises supervise and control the products better,promote the healthy development of enterprises and open up the international market.
