Claim 9:
10. The system according to claim 8, wherein,
in step S61, by establishing a connection between the mobile terminal and the BLUETOOTH master device, the BLUETOOTH master device sends connection channel frequency hopping route information to the at least one BLUETOOTH device scanning terminal; the at least one BLUETOOTH device scanning terminal realizes an autonomous frequency hopping according to the channel frequency hopping route information;
and after the autonomous frequency hopping to a corresponding channel is performed, a current channel connecting condition is monitored in real time;
in step S62, after the BLUETOOTH master device is connected to the mobile terminal, the channel frequency hopping route information is sent to the at least one BLUETOOTH device scanning terminal, and the at least one BLUETOOTH device scanning terminal deploys a first frequency hopping path according to the channel frequency hopping route information to obtain connected channel frequency hopping route information;
in step S63, after acquiring the connected channel frequency hopping route information, the BLUETOOTH master device sends the connected channel frequency hopping route information to the at least one BLUETOOTH device scanning terminal, and the at least one BLUETOOTH device scanning terminal deploys to a second frequency hopping path in real time according to the connected channel frequency hopping route information, tracks interaction data, and transmits back the packet information to the BLUETOOTH master device;
in step S64, interaction information between the BLUETOOTH master device and the mobile terminal, and physical position information about the at least one BLUETOOTH device scanning terminal are parsed according to the packet information; the RSSI signal strength is extracted according to the interaction information; the relative position and distance information between the BLUETOOTH master device and the mobile terminal is ascertained according to the physical position information about the at least one BLUETOOTH device scanning terminal and the RSSI signal strength.
