Abstract
In order to know more accurately the movement trajectory of the diagnosed person and to find the close contacts quickly,it is envisaged to develop an app software to realize the search of close contacts based on the positioning system.The GPS is used to obtain the user's high-precision three-dimensional location and the specific geographic location information such as the accurate general coordination time.Using third-party authorization to achieve real-name authentication,positioning based on GPS,recording the user's movement trajectory by building a Qt application,and identifying nearby users through Redis,which provides geolocation-related functions based on geohash and ordered sets,so as to more accurately locate people who are in close contact with the diagnosed person,send SMS reminders in time,and record their relevant information to reduce the risk of dissemination.of the risk of transmission.关键词
