Description

Distance monitor

Technical Field

The utility model relates to a sensor technical field specifically is a distance monitor.

Background

The RSSI of bluetooth is an indication of received signal strength, the unit of RSSI is dbm, in bluetooth, we can directly understand that the received signal strength of bluetooth is 10 × log P, P represents the received signal power, bluetooth sends broadcast, the received signal power is affected by the distance difference, and assuming that the transmission power is 1mw maximum, the RSSI is 0, that is, the RSSI obtained in an ideal state when your distance is nearest to bluetooth is 0, but in practice, this ideal state basically does not exist, so the RSSI is basically a negative number, and in bluetooth, when the distance is very close, the received RSSI has a signal value of about-50 dbm.

After the RSSI value is obtained, because in an ideal state, the RSSI value is 0 when all the transmitted power is received, then under the same environment, we can consider that the strength of the received-20 dbm signal value is greater than the strength of the received-50 dbm signal value;

and during novel epidemic situation coronavirus, do not have an effectual utensil can monitor the distance between the people, can't do the prevention well in time report to the police, for monitoring the distance between the people, for this reason, we have proposed a distance monitor to intensity data through bluetooth signal between two modules monitors the distance between two modules, thereby judges the distance between the people.
