Abstract
A wireless proximity system for responders to an emergency is presented. The wireless proximity system includes a command post comprising a command post communication link configured to transmit and receive information, a responder unit attached to a responder and comprising a unique electronic identifier and a ranging radio, the responder unit configured to receive a ranging query and transmit information including a unique electronic identifier via the ranging radio, and a leader unit.
Claims21
A wireless proximity system for responders to an emergency, the wireless proximity system comprising:
- a command post comprising a command post communication link configured to transmit and receive information;
- a responder unit attached to a responder and comprising a unique electronic identifier and a ranging radio, the responder unit configured to receive a ranging query and transmit information including a unique electronic identifier via the ranging radio;
- a leader unit comprising:
- a unique electronic identifier;
- a first antenna configured to communicate with the ranging radio of the responder unit of each responder;
- a second antenna configured to communicate with the command post communication link;
- a navigation module for determining a current position of the leader unit;
- and
- a ranging processor configured to control the navigation module, to control transmission of the ranging query to the responder unit, and to decode the information received from the responder unit.
A method of determining a proximity location of a responder, the method comprising:
- receiving, at a leader unit, information including a unique electronic identifier from a responder unit attached to the responder in response to a ranging query transmitted from the leader unit;
- receiving, at a command post, a leader unit reporting message from the leader unit in response to a request transmitted from the command post for the leader unit reporting message;
- storing, at the command post, the received leader unit reporting message in a leader unit message database;
- determining, at the command post, the proximity location of the responder using information from at least one stored leader unit reporting message;
- and
- displaying the calculated proximity location of the responder on a map,
- wherein the leader unit reporting message comprises:
- the unique electronic identifier received from the responder unit;
- a location of the leader unit acquired from a navigation module attached to the leader unit;
- and
- round-trip-air-time data measured by determining a difference between a first time at which the ranging query was transmitted from the leader unit and a second time at which the unique electronic identifier was received at the leader unit.
A leader unit configured to determine a proximity location of a responder, the leader unit comprising:
- a ranging radio configured to transmit a ranging query to a responder unit attached to the responder and to receive, in response to the ranging query, a ranging response comprising a unique electronic identifier of the responder unit;
- a navigation module configured to acquire a position of the leader unit;
- a main processor configured to decode the received ranging response and to extract the unique electronic identifier;
- a ranging processor configured to determine a round-trip-air-time by subtracting a first time when the ranging query was transmitted from a second time when the ranging response was received;
- and
- a communication link configured to receive a leader unit message request from a command post and to transmit a leader unit reporting message in response to the received leader unit message request,
- wherein the leader unit reporting message comprises:
- the acquired position of the leader unit;
- the received unique electronic identifier of the responder unit;
- and
- the determine round-trip-air-time data.
