Intruding incident information including ID / time / duration recorded in tracking bracelet
Bluetooth gateway received the contact broadcasting of bracelet and upload its to server. The server will store and analyze data and display relative information in display port.
In the period of epidemic outbreak,
the tracking bracelet can more accurately record the
social track of user; and make a more rapid response
to the infection time in the epidemic situation.
Wearing bracelets when get out,
user can clock in just before leave home.
And the bracelet will broadcast its own ID
(including health status code).
The surrounding bracelets will receive this
information, and mark the RSSI signal strength,
and time mark. The records will temporarily
packaged locally and can be sent to the
server through AP device.
In background server, the RSSI signal will be
converted into distance parameters.
With the location parameters,
user can locate through the map.
In some public places,
detectors can be installed to detect bracelet status.
And once detected any suspicious status,
the detectors will alarm. If anyone is infected,
relevant experts can modify the bracelet status on
the server through the AP device.
When two bracelets are within a dangerous distance,
if one of them is suspected or infected,
the bracelet will alarm in advance.
1. Bluetooth gateway
The gateway has been powered on will
automatically establish a TCP connection with the
set server and start the uninterrupted BLE
searching function, which will feedback the MAC
address, device name, broadcast type, broadcast
content and real-time signal strength of the BLE
devices around to the server in time.
.Support various devices
Any devices that conform to the BLE specification,
the BLE gateway can monitor them.
.Free operating cost
Bluetooth adopt the 2.4G frequency band that is
open globally. Operating cost is free.
