Abstract

A system and method for monitoring emergency personnel during an emergency incident is disclosed. The emergency personnel wear wireless communication units (CU) including a short-range radio and a long-range radio. CUs are configured to periodically transmit a unique identification from the short-range radio of the CU, receive the unique identification transmitted from the short-range radio of any other CU within range of the short-range radio, and transmit a data packet from the long-range radio, each data packet containing the unique identification of the CU and all the unique identifications recently received from any other CUs. The system can include an incident command monitoring system including a computing device to access a personnel and unique identifier database and analyze the data packets and initiate an alert if the unique identification associated with one of the emergency personnel has not been received by the communication unit of a team member.

Claims

1. A safety system to monitor a plurality of firefighting teams during an emergency incident, each firefighting team having a plurality of firefighters assigned as team members, the system comprising:

at least one communication unit of a plurality of communication units comprising a short-range radio and a long-range radio, each communication unit configured to periodically;

receive a unique identification from any other communication unit within a range of the short-range radio; and

transmit a data packet via the long-range radio, wherein the data packet contains the unique identification of the at least one communication unit and unique identifications recently received from any other communication units; and

an incident command monitoring system comprising;

a memory containing a database of the unique identifications and team assignments, in which each unique identification associated with a specific firefighter of the plurality of firefighters is assigned to identify a team member of one of the plurality of firefighting teams;

a long-range radio configured to receive data packets from the at least one communication unit; and

a central processor configured to;

analyze the data packets;

determine if each unique identification associated with each firefighter was received by the at least one communication unit based on the analysis of the data packets;

determine team affiliations based on the analysis of the data packets;

compare the team affiliations with the team assignments;

identify whether at least one firefighter of the plurality of firefighters is connected to an incorrect team based on the comparison; and

provide a notification in case the at least one firefighter disassociates from their assigned team.

2. The system of claim 1, wherein each communication unit is integrated into a wireless communication system of a self-contained breathing apparatus.

3. The system of claim 1, wherein each communication unit is integrated into a gas detector unit.

4. The system of claim 1, wherein the safety system further comprises a user display operably connected to the central processor and wherein the central processor is configured to command the user display to provide a visual representation of each firefighting team, including the firefighters in the firefighting team, and to provide a visual indicator of any firefighter whose unique indication has not been received by a communication unit of a team member of the firefighter'"'"'s assigned firefighting team.

5. The system of claim 1, wherein the central processor is configured to access the database and analyze the data packets to determine if a unique identification associated with one or more of the firefighters was received by another communication unit not associated with the assigned firefighting team of the one or more of the firefighters, and to initiate a notice if the unique identification associated with the one or more of the firefighters has been received by the other communication unit not associated with the assigned firefighting team of the one or more firefighters.

6. The system of claim 5, wherein the central processor is configured to determine which firefighting team is associated with the other communication unit not associated with the assigned firefighting team of the one or more firefighters, and wherein the notice includes both a name of the one or more firefighters and an identifier of the firefighting team associated with the other communication unit not associated with the assigned firefighting team of the one or more firefighters.

7. The system of claim 1, wherein the short-range radio is tuned to have a line of sight range of 30 feet and the long-range radio is tuned to have a line of sight range of at least 300 feet.

8. The system of claim 1, wherein the central processor is configured to initiate an alert if each unique identification associated with each firefighter is not received.

9. The system of claim 1, wherein the notification includes both a name of one of the firefighters and an identifier of the firefighting team associated with the other communication unit not associated with the assigned firefighting team of the one of the firefighters.

13. The system of claim 8, wherein the alert varies based on an identified connection of each firefighter, wherein the alert comprises at least one or more of color, text, icon and flash.

10. An incident command monitoring system comprising:

a memory containing a database of unique identifications and team assignments, in which each unique identification is associated with a specific firefighter of a plurality of firefighters and is assigned to identify a team member of one of a plurality of firefighting teams;

a long-range radio configured to receive data packets from at least one communication unit; and

a central processor configured to;

analyze the data packets;

determine if each unique identification associated with each firefighter was received by the at least one communication unit based on the analysis of the data packets;

determine team affiliations based on the analysis of the data packets;

compare the team affiliations with the team assignments;

identify whether at least one firefighter of the plurality of firefighters is connected to an incorrect team based on the comparison; and

provide a notification in case a firefighter disassociates from their assigned team or when a firefighter is not located nearby any firefighting team.

11. The system of claim 10, wherein the central processor is further configured to identify whether any firefighter is not connected to any other firefighter or any firefighter team based on the comparison.

12. The system of claim 10 further comprising a display, wherein the display is configured to provide a visual representation of each firefighter in each firefighting team.

14. The system of claim 10, wherein the central processor is configured to periodically receive signals indicative of biometric data corresponding to each firefighter of the plurality of firefighters, wherein the biometric data includes a core body temperature of the firefighter, a heart rate of the firefighter, a blood pressure of the firefighter, a rate of perspiration of the firefighter, a concentration of electrolytes in a fluid of the firefighter, a respiration rate of the firefighter, or combinations thereof.

15. The system of claim 10, wherein the central processor is configured to periodically receive one or more other signals received from one or more sensors indicative of an environmental metric, wherein the environmental metric includes a temperature of an atmosphere surrounding the one or more sensors, and a concentration of a flammable gas in the atmosphere surrounding the one or more sensors.
