Abstract

By incorporating automatic location and identity sensor equipment in an emergency or rescue scenario to facilitate a centralized tracking operation, fire fighters, rescuers, urban combat, etc. operations can be coordinated with greater safety by enabling the tracking of individuals. Passive and active RFID devices incorporated into helmets, badges, or PDA'"'"'s and cell phones can be used in conjunction with transceivers disposed about the rescue environment to generate real-time tracking and alarm status alerts for the rescuers. External database information, such as the layout of the building, as well as pre-existing communication and security controls in the building can be incorporated into the tracking system to provide increased synergy and effectiveness in rescue or tracking operations. The system is sufficiently modular to enable rapid and scalable deployment to rescue locations.

Claims

1. An emergency personnel tracking system, comprising:

a personal, mobile short range, passive RFID device;

a personal, mobile long range, active RFID device;

a fixed location transceiver, capable of initiating a communication from the passive RFID device, located within a rescue environment; and

a signal fusion console receiving communications from the transceiver, wherein the passive and active RFID devices are in communication with the transceiver to provide an information of the passive and active RFID devices, and the transceiver is in communication with the signal fusion console, wherein the signal fusion console relays a location information of the passive and active RFID devices for tracking of emergency personnel about the rescue environment, wherein the signal fusion console performs a check of the passive and active RFID devices and transceivers prior to distributing the transceivers, and wherein the check comprises determining a signal strength of the passive and active RFID devices and the transceivers, testing the passive and active RFID devices and the transceivers to determine whether functioning properly, and initial location testing.

2. The system of claim 1, wherein the passive RFID device is at least one or more of a device from a group consisting of a badge, mobile phone, Personal Digital Assistant (PDA), and communication-equipped helmet.

3. The system of claim 1, wherein the transceiver is in communication with the signal fusion console via a wireless link.

4. The system of claim 3, wherein there are a plurality of transceivers in communication with the signal fusion console.

5. The system of claim 4, wherein the plurality of transceivers are in communication with each other.

6. The system of claim 1, wherein the transceiver is in communication with the signal fusion console via a wired network.

7. The system of claim 1, wherein there are a plurality of signal fusion consoles.

8. The system of claim 7, wherein the plurality of signal fusion consoles are controlled in a master-slave configuration.

9. The system of claim 1, wherein the signal fusion console is coupled to an external database.

10. The system of claim 1, wherein the signal fusion console contains a status indicator, a user interface, and an external communication link.

11. The system of claim 1, wherein active RFID device is configured with an ID of the passive RFID device.

12. The system of claim 1, wherein the emergency personnel are rescued personnel.

13. A method for tracking emergency personnel in a rescue environment, comprising the steps of:

configuring personal, mobile passive RFID devices for emergency rescue operation;

configuring personal, mobile active RFID devices for emergency rescue operation;

configuring transceivers for communication with the passive and active RFID devices;

distributing at least one of the configured transceivers within the rescue environment;

tracking the passive and active RFID devices within the rescue environment via communications received from the at least one of the configured transceivers to a signal fusion console; and

performing a check of the passive and active RFID devices and transceivers prior to distributing the transceivers, wherein the check comprises determining a signal strength of the passive and active RFID devices and the transceivers, testing the passive and active RFID devices and the transceivers to determine whether functioning properly, and initial location testing.

14. The method according to claim 13,

wherein the step of performing comprises registration confirmation.

15. The method according to claim 13, further comprising the step of:

integrating layout information of the rescue environment into the signal fusion console.

16. The method according to claim 13, wherein the steps of configuring the RFID devices includes assigning an individual rescue personnel identifier to the RFID device.

17. The method according to claim 13, further comprising the step of:

locating the fusion control console at least one of an egress or ingress of the rescue environment.

18. The method according to claim 13, further comprising the step of:

initiating an alarm signal via the RFID device to the fusion console.

19. The method according to claim 13, further comprising the step of:

communicating information to an external center from the fusion control console, in response to a condition indicated by the fusion control console.

20. The method according to claim 13, further comprising assigning a rescued person an RFID device.

21. The method according to claim 13, further comprising assigning the transceivers to respective rescue teams.
