First, the system overview
The special meat industry in the food industry is a completely competitive industry. There are many participants, and there are basically no differences in products. Participants cannot form a monopoly on the market. “ Small scale and large groups †are typical characteristics of the main business of the meat wholesale market. The trading channels of the meat and vegetable wholesale market are mainly carried out by means of spot negotiation to determine the price. The transaction price is negotiated by the buyer and the seller according to the market conditions and settled by cash transaction. Most of the following problems exist:
1 ) The marketization of the main body of the vegetable wholesale market is low, small and scattered;
2 ) The layout of the vegetable wholesale market is unreasonable, the construction of basic supporting facilities is lagging behind, and the trading methods are backward;
3 ) The production and processing standards of vegetables are not standardized, and the pesticide residue detection system is not perfect;
4 ) The price of vegetable wholesale market changes rapidly and the stability is poor;
Second, the solution
Through the establishment of food (meat, vegetables, etc.) circulation traceability system will solve the above problems in the wholesale market of food (meat, vegetables, etc.), the system uses the industry-customized software and hardware solutions to achieve RFID high-frequency technology Based on the four-communication zigbee DTU and wireless routers, the product network is used as a quality and safety traceability information management model for food (meat, vegetables, etc.), and converts, integrates and mines many heterogeneous information. RFID is a key index information application service, and the demonstration applications of food (meat, vegetables, etc.) are all related to the cultivation (culture), distribution, logistics, product inspection, wholesale of food (meat, vegetables, etc.) supply chain. Information collection, recording and exchange in many aspects such as market sales, low-cost and high-efficiency hardware solutions and complete information sharing and exchange software technology support platform are seamlessly combined, and strict data authentication and access control design mechanisms are involved in food for different objects ( Quality and safety application services for meat, vegetables, etc. provide a solid foundation. The construction of the platform will help guide the large-scale scientific production in rural areas, optimize the information management process of traditional wholesale circulation enterprises, simplify and accelerate the exchange of information between enterprises and government regulatory departments, and fully satisfy consumers' right to know about food information.
Third, the system consists of:
The system according to the application software development project both the actual situation, the use of C / S + B / S combined mode, each of the upper-level management platform and the service subsystem using B / S model, a uniform distribution on the management platform level account, wholesale electronic settlement system using C / S mode to achieve, while the electronic retail market, said data collection also by C / S mode, the handset market inspection management platform connected to the upper level through the GPRS network, transmission network band, said ZIGBEE by networking, unified management platform and the level ROUTER connected by GPRS or directly, level platform architecture, component-oriented software architecture and services.
Based on the overall technical framework, the technical system for the circulation of meat dishes is established, which mainly includes the meat circulation traceability technical standard system, the meat circulation traceability construction norm system, the information security system, the hardware support platform, the system support platform, the application service platform, Based on the technical platform and the external interface, each subsystem is planned and designed, the overall goal is refined into the subsystem's goal, the system structure is decomposed, and the subsystem's architecture and functional model are designed. Each functional module designs a corresponding information entity to form a subsystem information model, and designs the links between the subsystems according to the main business processes and information interfaces.
Fourth, the data center platform
4.1, the main function modules are as follows:
1 ) Rapid response to emergency incidents: The traceability system for food (meat, vegetables, etc.) is based on the traceability of food (meat, vegetables, etc.). The first time is to identify the upstream and downstream links generated by the emergency, lock the source, and track the flow. However, the warning information issued to relevant business entities and consumers has not been realized, and further research and implementation of intelligent means should be used to support relevant departments to carry out emergency disposal of problem products, such as dismantling, delisting, and recall.
2 ) Summarize the traceability information of the whole region: transform the existing platform, realize the hierarchical storage and retrieval according to the origin, circulation node, business owner, traceability code, etc., and form the traceability information chain of food (meat, vegetables, etc.) in the region.
3 ) Comprehensive analysis and utilization of traceability information: According to the management needs of the national food (meat, vegetables, etc.) circulation industry, establish a statistical analysis index system and analysis model library, and set specific statistical analysis items, by day, week, month, year, etc. Cycle, sub-variety, quantity, price and other indicators, comprehensive use of year-on-year, ring ratio, trend, ranking and other methods for statistical analysis.
4 ) Monitoring and managing circulation nodes: formulate the retrospective work assessment management system and dynamic assessment indicators, regularly conduct assessment and intelligent assessment of the traceability work of each circulation node, and realize the timeliness and standardization of information transmission of each circulation node on a quarterly or monthly basis. Horizontal and vertical analysis of authenticity, continuity. Establish a problem discovery model library, form a unified method for screening, qualitative and degree evaluation of problems, effectively monitor the information reporting of each circulation node, and promptly warn of problems.
  5 ) Provide comprehensive information services: rely on the China Market Order Network sub-station to set up an information release window, and provide inquiries and report complaint services for transaction entities and consumers through channels such as the Internet, telephone hotline and SMS.
  6 ) Supervision by government departments
Business supervision: quarantine the pigs in the slaughterhouse, sample the vegetable residues in the wholesale market, and upload the quarantine results to the data center in real time through the terminal equipment.
Regulate the transaction situation of slaughterhouses and wholesale markets; issue identification cards to vegetable business entities; manage hardware devices in circulation, including handheld devices, electronic scales and other equipment.
Through the handheld machine, check the daily source information of the operators, and urge the wholesale market, farmer's market, mall promoters, and edible agricultural product sellers to fulfill their sales safety responsibilities, strengthen the supervision and management of vegetables in the circulation chain, strictly control the ticket management system, and promptly investigate and circulate the circulation. The illegal operation of the link vegetables.
Supervise the import and sales of meat and vegetable products of food processing enterprises, and at the same time do a good job in promoting the market access of meat and vegetables in the processing sector.
Supervise hospitals, schools and other units canteens and catering service operators to earnestly fulfill the responsibility for the quality and safety of meat and vegetable products, supervise the establishment of the purchase and registration system for meat and vegetables, and promptly investigate and deal with illegal activities in the catering and consumption sectors.
Market management party: The market management party is responsible for verifying the purchase vouchers of farmers' market stalls and checking the source of vegetables; ensuring that the electronic scales sold in the market must be traceable electronic scales that meet the specifications; statistical analysis of daily market sales.
