Method and system for measuring and warning social distance based on mobile phone embedded with uwb module

Abstract

The invention provides a method and a system for measuring and giving early warning on a social distance by using a mobile phone embedded with a UWB module, and belongs to the technical field of distance measurement positioning and communication of an ultra wide band UWB technology. The system comprises a plurality of smart phones embedded with UWB modules and a server. In the method, two smart phones embedded with the UWB modules establish a communication connection relationship through searching; if the distance between the two mobile phones is less than or equal to a safe social distance, the two mobile phones respectively transmit prompt early warning to respective users and exchange social IDs of the users with each other, and then upload the information of the social IDs, the currentmoment, the geographic positions and the contact time of the users of the opposite side to the server to complete social registration; and the server can send out early warning to the related socialIDs according to social registration when necessary. According to the method and the system, a positioning base station is not needed, the social distance information of the crowd can be obtained andearly warning can be performed only through the intelligent equipment embedded with the UWB module and the mobile communication network, and the method is simple and easy to implement.

Description

technical field [0001] The invention belongs to the field of ultra-wideband UWB technology ranging positioning and communication technology, and particularly proposes a method and system for measuring and warning social distance based on a mobile phone embedded with a UWB module. Background technique [0002] Measuring and recording the social distance between people, and giving early warning when the social distance is within a safe range, has gradually become a new demand for people's social activities. The population flow in social life is complex, and people may have close contact with a large number of strangers through public spaces or places such as buses, subways, airplanes, ships, supermarkets, shopping malls, and entertainment venues. When a large-scale infectious disease outbreak occurs, close contact between people may become the main way of disease transmission. If the social contact distance information between people can be obtained, it can give an early warn...

AI Technical Summary

Problems solved by technology

[0011] 1) The above systems and methods need to use multiple positioning base stations, and can only obtain the positioning information of people in the fixed space covered by the positioning base stations

However, the actual space for social activities is very wide. It may be indoors, outdoors or even in public spaces for sports. It is expensive to deploy and locate base stations in all social spaces;

[0012] 2) Users need to wear additional customized positioning tags, which increases the carrying equipment of travelers and does not meet the travel habits of most people;

[0013] 3) The location information of the person wearing the positioning tag can only be obtained by the information management module connected to the positioning base station. The positioning tag itself cannot obtain the specific information of other tags (personnel) within a safe social distance in real time, and cannot give real-time warning;

[0014] 4) It is not compatible with the existing mobile communication network, and it is difficult to popularize the solution. It is only suitable for small fixed social space occasions
