As in recent years, many of the food safety problem happened frequently threatened consumer health, caused a worldwide attention, also influence the food industry’s health, sustainable and stable development. Due to the problems of cold chain interrupt, lax supervision, software and hardware equipment backward, and industry standard imperfect etc, a lot of cold chain food waste, cold chain food safety accidents occur frequently, and this seriously harm to people’s daily lives:The main research status of cold chain food industry development based on Internet of things technology in our country are analyzed, selects the pork as the research object; Analyzes the Internet of things applications research in foreign and its application development trend in the food cold chain logistics; According to the research status at home and abroad, summarizes the paper the technical route and structure framework; the key technologies are analyzed and summarized in this paper, the technical architecture and technical analysis are detailed described; At the same time, further analyzes the existing problems,constructs the static and dynamic model of the factors influencing the retrospective study; According to the software development process, complete the system demand analysis from the perspective of business process and data flow, elaborates the user requirements from government regulators, related enterprises and consumers three aspects; In detail elaborates overall design and detailed design of the cold-chain food safety traceability system, including system physical structure design, system logic structure design; In the detailed design section, designs system function module and interface; Finally, test system interface and functional security,test results show that system satisfies the requirement of system design. |
