Abstract

There is disclosed a telemetry monitoring system including a central monitoring unit configured to display data regarding one or more portable devices, each associated with the breathing apparatus of a user. The system further includes removable data storage connected to the central monitoring unit and configured to store system status data of the central monitoring unit as recovery data, the system status data defining an operational status of the central monitoring unit. In the event of a failure of the telemetry monitoring system, the telemetry monitoring system can be recovered by restoring the recovery data to the central monitoring unit or a replacement central monitoring unit from the removable data storage.

Claims

1. A method of wirelessly monitoring a plurality of users wearing breathing apparatus comprising the steps of:

wirelessly monitoring a plurality of portable devices, each comprising a personal alert safety system and each associated with a breathing apparatus of a user, using a central monitoring unit which wirelessly receives telemetry data containing information regarding the status of the breathing apparatus and/or the user from each of the portable devices;

displaying the telemetry data received by the central monitoring unit from each of the plurality of portable devices at the central monitoring unit;

storing system status data of the central monitoring unit as recovery data in removable data storage removably connected to the central monitoring unit, wherein the system status data comprises the telemetry data received by the central monitoring unit from each of the plurality of portable devices, and also comprises data generated at the central monitoring unit including information regarding the selection and/or allocation of users into groups during an emergency response, and/or information regarding which of the users are currently logged onto their respective portable device; and

restoring the recovery data from the removable data storage to the original central monitoring unit or a replacement central monitoring unit in the event of a failure of the telemetry monitoring system,

wherein said recovery data creates a snapshot of an emergency response situation which, after a failure, is used to restore the original central monitoring unit or a replacement central monitoring unit to the state it was in immediately prior to the failure, thereby allowing the users to be immediately located.

2. A telemetry monitoring system comprising:

a central monitoring unit configured to display data regarding one or more portable devices each associated with a breathing apparatus of a user; and

removable data storage removably connected to the central monitoring unit and configured to store system status data of the central monitoring unit as recovery data, the system status data comprising data generated at the central monitoring unit including information regarding the selection and/or allocation of users into groups during an emergency response, and/or information regarding which of the users are currently logged onto their respective portable device;

wherein, in the event of a failure of the telemetry monitoring system, the telemetry monitoring system can be recovered by restoring the recovery data to the central monitoring unit or a replacement central monitoring unit from the removable data storage;

wherein said recovery data creates a snapshot of an emergency response situation which, after a failure, is used to restore the original central monitoring unit or a replacement central monitoring unit to the state it was in immediately prior to the failure, thereby allowing the users to be immediately located.

3. The telemetry monitoring system as claimed in claim 2, further comprising one or more portable devices.

4. The telemetry monitoring system as claimed in claim 3, wherein each of the one or more portable devices comprises a personal alert safety system device.

5. The telemetry monitoring system as claimed in claim 2, wherein the system status data comprises telemetry data received at the central monitoring unit from the one or more portable devices and/or instruction data transmitted from the central monitoring unit to the one or more portable devices, wherein the telemetry data contains information regarding the status of the breathing apparatus and/or the user.

6. The telemetry monitoring system as claimed in claim 2, wherein the central monitoring unit comprises an integrated data storage unit which is configured to store a log file in which the system. status data is recorded periodically, the log file forming recovery data, and wherein the telemetry monitoring system can be recovered by restoring the recovery data to the central monitoring unit from the integrated data storage unit in the event of a failure of the telemetry monitoring system.

7. The telemetry monitoring system as claimed claim 2, wherein the removable data storage comprises one or more removable storage units, wherein each such removable storage unit is removably connected to the central monitoring unit.

8. The telemetry monitoring system as claimed in claim 7, wherein the central monitoring unit is configured to store at least some of the system status data on at least one of the one or more removable storage units directly removably connected to the central monitoring unit.

9. The telemetry monitoring system as claimed in claim 7, further comprising:

a wireless communication unit removably connected to the central monitoring unit and configured to perform wireless communication with each of the one or more portable devices.

10. The telemetry monitoring system as claimed in claim 9, wherein the wireless communication unit comprises one of the one or more removable storage units.

11. The telemetry monitoring system as claimed in claim 10, wherein the wireless communication unit is configured to store at least some of the system status data on at least one of the one or more removable storage units.

12. The telemetry monitoring system as claimed in claim 2, wherein the central monitoring unit is configured to identify recovery data upon start up of the central monitoring unit and, if instructed, to restore the recovery data to the central monitoring unit.

13. The telemetry monitoring system as claimed in claim 2, wherein the central monitoring unit comprises an electronic entry control board.

14. A method for data recovery in a telemetry monitoring system, wherein the telemetry monitoring system comprises a central monitoring unit configured to display data regarding one or more portable devices each associated with breathing apparatus of a user, the method comprising the steps of:

storing system status data of the central monitoring unit as recovery data in removable data storage removably connected to the central monitoring unit, the system status data comprising data generated at the central monitoring unit including information regarding the selection and/or allocation of users into groups during an emergency response, and/or information regarding which of the users are currently logged onto their respective portable devices; and

restoring the recovery data from the removable data storage to the central monitoring unit or a replacement central monitoring unit in the event of a failure of the telemetry monitoring system;

wherein said recovery data creates a snapshot of an emergency response situation which, after a failure, is used to restore the original central monitoring unit or a replacement central monitoring unit to the state it was in immediately prior to the failure, thereby allowing the users to be immediately located.

15. The method as claimed in claim 14, wherein the system status data comprises telemetry data received at the central monitoring unit from the one or more portable devices and/or instruction data transmitted from the central monitoring unit to the one or more portable devices.

16. The method as claimed in claim 14, wherein the central monitoring unit comprises an integrated data storage unit, the method further comprising:

periodically recording the system status data in a log file stored on the integrated data storage unit as recovery data; and

restoring the recovery data to the central monitoring unit from the integrated data storage unit in the event of a failure of the telemetry monitoring system.

17. The method as claimed in claim 14, wherein the removable data storage comprises one or more removable storage units, wherein each such removable storage unit is removably connected to the central monitoring unit.

18. The method as claimed in claim 17, further comprising the central monitoring unit storing at least some of the system status data on at least one of the one or more removable storage units directly removably connected to the central monitoring system.
