Abstract

A monitoring system ( 100 ″) is for aeronautical personnel ( 99 ), such as aircraft operators, pilots, co-pilots or passengers of airplanes or aircraft, such as aircraft or helicopters of civil or military aviation, passenger aircraft in scheduled or charter traffic, in particular also ultra-fast aircraft. The monitoring system includes a sensor system ( 60 ) for a measurement-based monitoring of the gas concentration. The operation of the monitoring system ( 100 ″) can be configured by an external input/output unit ( 450 ) or an external output unit ( 460 ).

First claim

What is claimed is:

1 . A system for monitoring breathing gas support in airplanes or aircraft, the system comprising:
a monitoring system mobile module configured to be carried in a pocket in one aviator, pilot, copilot or aircrew, or attached on clothing of the one aviator, pilot, copilot or aircrew, the mobile module comprising:
a sensor system, the sensor system comprising at least one sensor that is configured as an oxygen sensor, a carbon dioxide sensor, a carbon monoxide sensor or as at least one further gas sensor wherein the sensor system is configured to provide a qualitative and a quantitative measurement-based detection of a concentration of oxygen and/or a concentration of carbon dioxide and/or a concentration of carbon monoxide, and/or a concentration of another gas;
a control unit connected to the sensor system and configured to organize, monitor, control and/or regulate a sequence of the measurement-based detection of the gas composition of air, breathing air or breathing gases in an airplane or aircraft; and
a mobile module wireless data interface;

a breathing gas mask connected to the sensor system by a measured gas line; a memory; a pressure sensor; a shut-off valve; wherein the control unit is further configured, in cooperation with the pressure sensor, the shut-off valve, and the memory, to determine a current pressure level in the breathing gas mask; and an external input/output unit, wherein the external input/output unit is configured to display, signal or issue an alarm based on the measurement-based detection and/or based on results of the concentration of oxygen in the breathing gas detected by the sensor system, wherein the external input/output unit is configured as a wristwatch worn by the one aviator, pilot, copilot or aircrew or worn by another aviator, pilot, copilot or aircrew, wherein the external input/output unit is configured for signaling or alerting with a visual, acoustic or tactile output of information, signals, alarms and/or alerts to the one aviator, pilot, copilot or aircrew or the other aviator, pilot, copilot or aircrew, the wristwatch comprising wristwatch wireless data interface, wherein the system is configured to establish a wireless data link between the mobile module wireless data interface and the wristwatch wireless data interface, the external input/output unit being connected by the wireless data link to the control unit of the monitoring system mobile module, wherein the wireless data link enables wireless data exchange for two-way signaling or alerting from the monitoring system mobile module of the one aviator, pilot, copilot or aircrew to another aviator, pilot, copilot or aircrew and/or signaling or alerting from a monitoring system mobile module of the other aviator, pilot, copilot or aircrew to the one aviator, pilot, copilot or aircrew.

2 . A system according to claim 1 , wherein the external input/output unit is configured to enable a remote control of the monitoring system.

3 . A system according to claim 1 , wherein the external output unit is further configured as a headphone or structure-borne sound receiver or a body sound receiver arranged on the body of an aircraft pilot or co-pilot, wherein the external output unit is configured for an acoustic or tactile output of signaling or alerting to the pilot or co-pilot.

4 . A system according to claim 1 , wherein the wireless data link enables communication from the monitoring system of the pilot or copilot to at least one other subscriber in a data network.

5 . A system in accordance with claim 1 , wherein:
the control unit is configured to receive at least one environmental parameter and/or at least one situational parameter; and the system further comprises a data interface for receiving and/or providing environmental parameters and/or situational parameters and/or for interfacing between the control unit and the external system.

6 . A system in accordance with claim 1 , wherein the sensor mechanism comprises an additional sensor configured to determine and/or to measurement-based detect environmental parameters and/or to determine and/or to measurement-based detect situational parameters and wherein the sensor mechanism is configured for providing the environmental parameters and/or situational parameters.

7 . A system in accordance with claim 1 , further comprising:
a gas transport module comprising a pump with a gas port for connection with a measured gas line to deliver quantities or partial quantities of breathing gas or breathing air from a measuring point, via the measured gas line, to the sensor mechanism; and a gas inlet and/or gas outlet of the system, wherein the gas transport module is arranged at the gas inlet of the monitoring system mobile module or the gas transport module is arranged at the gas outlet of the monitoring system mobile module.

8 . A system in accordance with claim 7 , further comprising: an additional gas port; and a reversing valve or changeover valve.

9 . A system in accordance with claim 8 , further comprising an additional pump arranged at the additional gas port.

10 . A system in accordance with claim 7 , wherein the control unit is configured to control the gas transport module.

11 . A system in accordance with claim 1 , wherein the control unit is configured to determine and/or detect an alarm situation and to organize an alarm generation or an alarm output and/or provide an alarm signal.

12 . A system in accordance with claim 11 , wherein the control unit is configured to also take into consideration an environmental parameter and/or a situational parameter in the organization of the alarm generation or alarm and/or to also include the environmental parameter and/or the situational parameter in the organization of the alarm generation.

13 . A system in accordance with claim 1 , further comprising an energy storage device.

14 . A system in accordance with claim 1 , further comprising at least one operating element, for operating the system.

15 . A system in accordance with claim 1 , further comprising at least one display element for displaying events, situations, status data, current measured values, past measured values, measured variables derived from measured values, including maxima or minima, mean values, trends, statistics, events and alarm situations.

16 . A system in accordance with claim 1 , further comprising an input element configured to receive user input comprising a user initiated annotation, a triggering, a starting or an ending of defined situations, defined actions or states at the system.

17 . A system in accordance with claim 16 , wherein the input element is configured as an acceleration sensor.

18 . A system in accordance with claim 1 , further comprising a memory for storing measured values and measured variables derived from the measured values including maxima or minima, mean values, trends, statistics, events, alarm situations.

19 . A system in accordance with claim 11 , further comprising a system memory, wherein the control unit is configured to use predefined threshold values, which are storable for determined values of gas concentrations in the system memory, in the organization of the alarm generation.
