Abstract

A method and an arrangement which locates people within a region which is to be monitored and can be used in a mobile manner. At least one transmitter working in an ultra-wide band (UWB) is used, in addition to at least one transmitter/receiver device working in the ultra-wide band (UWB) and a receiver working in the ultra-wide band (UWB). The transmitter is arranged in a fixed manner when used in region which is to be monitored, the transmitter/receiver device is disposed on a person who is to be located and the receiver is arranged on a monitoring computer arranged outside the region which is to be monitored and is connected thereto.

Claims

1. A method for locating a person within a monitored area in a mobile application, in which at least one transmitter operating in an ultrawide band (UWB) spectrum, at least one transmit/receive device operating in the ultrawide band (UWB) spectrum, and a receiver operating in the ultrawide band (UWB) spectrum are used, the transmitter being arranged stationary in the monitored area during the operation, the transmit/receive device being disposed on the person to be located and the receiver being arranged on a monitoring processor located outside the monitored area and connected thereto, the transmitter and the transmit/receive device additionally operating based on a LORAN-C positioning system and position data determined by the LORAN-C system being combined using ultrawide band technology and corrected.

2. A method according to claim 1, characterized in that at least one other stationary transmitter is provided in the monitored area.

3. A method according to claim 2, characterized in that the additional transmitter is arranged outside the plane defined by the first stationary transmitter.

4. A method according to claim 1, characterized in that the monitored area is an inside of a building and the stationary transmitter is or are installed in a prominent location of the building that are is easily accessible.

9. The method of claim 2 wherein the monitored area is an inside of a building and said at least one transmitter and said at least one other stationary transmitter are installed in prominent locations of the building that are easily accessible.

10. The method of claim 3 wherein the monitored area is an inside of a building and said at least one transmitter and said at least one other stationary transmitter are installed in prominent locations of the building that are easily accessible.

5. An arrangement for locating persons within a monitored area in a mobile application, comprising at least one transmitter operating in an ultrawide band (UWB) spectrum, at least one transmit/receive device operating in the ultrawide band (UWB) spectrum, and a receiver operating in the ultrawide band (UWB) spectrum, the transmitter being arranged stationary in the monitored area during the operation, the transmit/receive device being disposed on a person to be located and the receiver being arranged on a monitoring processor located outside the monitored area and connected thereto, the transmitter and the transmit/receive device additionally operating based on a LORAN-C positioning system and the position data determined by the LORAN-C system being combined using ultrawide band technology and corrected.

6. An arrangement according to claim 5, characterized in that at least one other stationary transmitter is provided in the monitored area.

7. An arrangement according to claim 6, characterized in that the additional transmitter is arranged outside the plane defined by the first stationary transmitter.

8. An arrangement according to claim 5, characterized in that the monitored area is the inside of a building and the stationary transmitter is installed in a prominent location of the building that is easily accessible.

11. An arrangement of claim 6 wherein the monitored area is an inside of a building and said at least one transmitter and said at least one other stationary transmitter are installed in prominent locations of the building that are easily accessible.

12. An arrangement of claim 7 wherein the monitored area is an inside of a building and said at least one transmitter and said at least one other stationary transmitter are installed in prominent locations of the building that are easily accessible.
