With the wide spread of intelligent terminals, a variety of location-based business applications continue to emerge. We began to think about the analysis and application of location-based information big data, using big data technology to transform the existing industry, so as to better deal with epidemic disasters and other issues. For the novel Coronavirus, if artificial influenza virus infection or infection is detected by artificial means, it is easy to cause a series of problems, such as low efficiency, potential infection, and deliberately concealing travel history and contact history, which will have certain impact on epidemic prevention and control. Therefore, with the huge amount of data and the rapid growth of service demand, it is very urgent and necessary to isolate and confirm suspected cases based on big data analysis of location information. The big data analysis platform of location information can analyse the user’s location information, form the user’s trace, and provide more comprehensive information for epidemic control.
