Monitoring Worker Exposure to COVID-19 and Other Occupational Risks Using BLE Beacons

The COVID-19 pandemic has become a public health priority during 2020. Social safety distance is one of the most effective strategies to stop spreading virus, as it reduces dose infectious particles that person can receive. Real-time location systems (RTLS) based on ultrawideband (UWB), radio frequency identification (RFID), Global Position System (GPS), or Bluetooth Low Energy (BLE) help keep workers safe at workplace. aim current paper develop dosimeter proposal monitor and control exposure time between BLE beacon technology considering viral load. Our set beacons estimation by filtering RSSI measurements with Gaussian extended Kalman filter. According estimated proximity values time, finite state machine will alarm when worker receives maximum defined authorities. proposed system be applied prevent any risk eliminated reduced controlling distances and/or exposition occupational risk. robust, inexpensive, respects privacy workers, its accuracy higher than existing smartphone applications. In future situations, easily updated particle related new agent. protect from additional incorporating extra identified such thermal, noise, radiation.
