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

目的 面向冬奥会食品安全应急保障应用场景,构建“多元集成、有效控制、智慧保障”解决方案。方法 综合运用应急风险评估方法,基于知识图谱集成食品供应链有害因子智能化快筛装置与方法,采用大数据、人工智能和移动互联网技术构建奥运食品供应链风险预警智慧管控系统,智能生成食品供应链不同环节、不同有害因子应急预案,从而面向系统不同层级用户实现精准推送。结果 运用智能化快筛技术和预测预警技术,该预案在北京冬奥会及冬残奥会(张家口赛区)2022食品安全突发事件应急演练和冬奥会测试赛、正式比赛期间供奥食品企业食品安全保障工作中得到实际应用。结论 以食品安全风险分析和数据治理为主线、以快筛技术智能化集成为手段,以智慧风险预测与智能预警交互为纽带,推动了食品供应链有害因子系统感知、靶向识别、精准确证,提高了重大活动食品安全应急保障能力。

Objective A “multi-integration,effective control,and intelligent guarantee” solution was built for the application scenarios of food safety emergency support for the Winter Olympics.Methods With 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.Results Using 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.Conclusion Taking 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.
