With the further development of the COVID-19, it has become very important to maintain the social distance of personnel in the workplace. Appropriate social distance can prevent the effective spread of COVID-19, which requires every person to practice. However, it is difficult to realize the problem of social distance in a timely manner during work, so Hangzhou Tengdong Information Technology Co., Ltd. urgently launched a social distance product based on the UWB principle. The product does not need to deploy a UWB base station, but directly judges whether it is beyond the normal social distance by calculating the distance between the UWB tags. If two users enter the social distance, the tags will give an alarm.
The deployed unit can also place information collection base stations at the places where employees enter and exit, to collect the current number of employees in the area and the number and time of employees entering the social distance.

The deployment method of this system is very simple. If data collection is required, only UWB collection base stations are arranged at the entrance of each area. If data collection is not required, only UWB social distance badges need to be equipped for each employee
The functions implemented by this system are as follows:

1. Social distance: Customize social distance, and the terminal will issue an alarm within the social distance.
2. Data reporting: Count the personnel in contact and report through UWB network.
3. Personnel statistics and roll call: Count the number of personnel in the current area.
4. Social statistics: Conduct statistics on other terminals that each terminal comes into contact with within social distance.
5. Distance setting: Social distance can be customized, ranging from 0.5m-25m.
6. Open API: Supports API openness and provides secondary development.
7. Terminal data entry: Enter personnel information, match it with the terminal, and manage personnel
8. Terminal idle alarm: Set working hours and alert the non moving terminal during working hours
