This is a low power battery operated BLE device that is fixed the place of quarantine person. This device creates a wireless radial fence. The fence has a radius of around 15 feet, which can be adjusted with the transmitting power of zone device. This zone device transmits beacon at a regular interval of 15 secs. Each device has a unique ID.
Pendant unit is like zone device. It is a low power BLE pendant. It is worn by quarantine person. This unit transmits beacon at regular interval, with a default as 15 sec. This is an IP67 device and hence, can sustain water spray, shower, sweat, etc. Also, the chain used can be sealed after wearing so that the quarantine person cannot remove the same. Also, an electrical feedback can be enabled with design of pendant device. This feedback can alert the system if someone tries to break the chain.
A mobile application is installed on both quarantine person and one of the guardians. This application uses GPS and BT of mobile to track the information about quarantine person.
While the devices are installed in quarantine zone and quarantine person, all information about quarantine person, devices and location information is captured in mobile application. This data is registered on cloud portal.
The application runs in background and keeps on scanning for nearby BLE tags. This data is periodically transferred to cloud. The signals / beacons from both zone device and pendant are captured in mobile application. The algorithm built in mobile application alerts the quarantine person if he moves out of quarantine zone. Same information is also transferred to cloud.
Cloud application is hosted on IoT servers. This application captures data from all mobile applications and displays the location of all quarantine persons on map. It also, shows the active alerts, whenever a person moves out of quarantine zone.
Additional intelligence can be embedded in cloud application, to automatically place a call via IVR to any police station or concerned government authority.
We can also enable the pendant device with additional functionalities with the help of addition of sensors and AI as below,
The mobile application can be integrated with Arogya setu application, so that same application be utilized to gather the information from these devices. Further to this, Arogya setu application can also alert the people in vicinity, if any quarantine person is roaming around. Also, tracking of such quarantine person can be easily enabled, with the help of Arogya setu application.
