【摘要】 新冠肺炎疫情下,作为人员密集场所的高校校园应具有应急防控机制来控制疫情的扩散。该机制中的一项重要手段是通过用户终端无线数据来分析和追踪疫情相关人员的活动轨迹。为了保证用户终端数据的连续性与完整性,基于Syslog数据接收的方式整合数据是最优的。结合校园网关Syslog数据信息的特点,定位完整的用户无线轨迹信息,有效地提高了定位用户活动场所的准确性。更多还原

【Abstract】 Under the COVID-19 epidemic,college campuses,which are crowded places,should have emergency prevention and control mechanisms to control the spread of the epidemic.An important means of this mechanism is to analyze and track the movement trajectories of epidemic-related personnel through wireless data from user terminals.In order to ensure the continuity and integrity of user terminal data,it is optimal to integrate data based on Syslog data reception.Combined with the characteristics of the Syslog data information of the campus gateway,the complete wireless trajectory information of the user can be located,which effectively improves the accuracy of locating the user’s activity place.更多还原
