Knowledge map and intelligent rapid screening technology of harmful factors in food supply chain of Winter Olympics

Abstract

ObjectiveA “multi-integration， effective control， and intelligent guarantee” solution was built for the application scenarios of food safety emergency support for the Winter Olympics.MethodsWith emergency risk assessment method， the intelligent quick screening device and method for harmful factors in the food supply chain were integrated based on the knowledge map， and big data， artificial intelligence and mobile internet technologies were used to construct an intelligent management and control system for risk early warning of the food supply chain in the Olympics to realize that the emergency plan for different links and different harmful factors in the food supply chain was intelligently generated，which were precisely pushed to users at different levels of the system.ResultsUsing intelligent rapid screening technology and prediction and early warning technology， it has been practical application in the food safety emergency drills for food safety emergencies in the Beijing Winter Olympics and Winter Paralympics （Zhangjiakou Area） 2022， and guarantee of food safety for Olympic food companies in the Winter Olympics test competitions， and the official competitions.ConclusionTaking food safety risk analysis and data governance as the main line， intelligent integration of quick screening technology as a means， and intelligent risk prediction and intelligent early warning interaction as a link， the systematic perception， targeted identification， and accurate verification of harmful factors are promoted in the food supply chain to improve the food safety emergency support capability for major events.
