"To eat for days, food safety first", human survival, economic growth, social progress, always without food, is inseparable from security, health, nutrition and the food. Recent years, with the residents'living standard are continuously improved and the issue of food security becomes more and more obvious. "Lean" and "water injection pork" when heard, bring to people's health was seriously affected. Now for the meat in the series of problems occurred during production, circulation, date back quite troublesome, even some which will never investigate recalls, establishing security and traceability in meat consumption of goods, guarantee people's consumer safety management level of the people's livelihood has become considered industry works. As per present situation, after getting relative information of pig cultivation, slaughter and circulator, using some relative research of this area as a source of reference, design and achieve one set of information retroactive system for quality safety of meat. Back chain meat products in using information technology to solve the complexity of implementation for meat traceability and tracking control system strictly adhere to the "source of controlled production, processing and quality control of retail, wholesale flow control, access" overall thought, building an information reliable, operation efficiency, responsibility clear, easy to operate, sharing information with the public information platform.At first, this article researched the information actuality of meat management industry, analyzed the demand of meat regulation, and made demand of the whole systematic development. Taking database plat as center, seven systems collect software technology, mechanics of communication, barcode technology, RFID technology, IC card, handheld terminal technology, data encryption technology and so on, and integrate, deal and save in data center to form whole information backward through collecting business data of pig butcher, wholesale, retail and consumption. All products used for information transfer follow network protocol and request of transmission standards (Such as IC card ISO 14443 A standard, electronic scale of communication follows the RS232, TCP/IP communications), achieve communication and sharing in network systems. Then it designs architecture of whole system, describes contents of system, system modeling, logic sketch map and database design, related technology for system achievement, it does system selection for some of system hardware and software. Finally tells the system to achieve, from uniqueness, data delivery, regulatory functions, and meats date back to illustrate, detailing the implementation of all parts of the system function.Because of this design dates back platform to manage summary data not only, to complete information management and data among multiple data acquisition subsystem of the upload, so on the feature set we must consider various different requirement. The system contains one city-level data center and seven data acquisition subsystems, each trace subsystem also contains a number of different modules, used to implement different features. After the completion of the system can not only complete the basic information management, business data is summarized, can also trace code to trace and recall. Meat slaughtered in the system to achieve a regional collection and aggregation of data, circulation, consumption, to question quick location lock and timely processing of meat, for pig source recognition, product flow can be verified, quality responsibility can be traced back. Enables comprehensive monitoring business process manage time, increase the purposefulness and effectiveness of the regulatory work, effectively improve the efficiency of law enforcement, and rapid response capability, Real-time monitoring can be implemented in the market monitoring, in this way we don't need a lot of manpower, material and financial resources to collect information and the government departments can get the information of the market monitoring at any time. And the information can be reported to the Provincial Government leaders, to provide the scientific data for the making of the Contingency plans for market.
