Process, system and alarm management system for analyzing data of a mobile gas measuring device

A system for measuring a concentration of a gas in a monitored area, the system comprising:

• mobile gas measuring devices generating measured data;
• a central data processing unit;
• and
• transmission means for a unidirectional or bidirectional data transmission between the mobile gas measuring devices and the central data processing unit, the transmission means transmitting measured data from one of the mobile gas measuring devices to the other of the mobile gas measuring devices or to the central data processing unit or to the other of the mobile gas measuring devices and to the central data processing unit, wherein the system is configured to:
• compare the measured data with a limit value, stored in any of the mobile gas measuring devices and the central data processing unit, to determine if there is a limit value violation comprising an inadmissible overshooting or undershooting of the limit value;
• generate an alarm control signal suitable for taking an action by any of the mobile gas measuring device, the additional gas measuring device and the central data processing unit, for the limit value violation;
• determine a hazard potential in any of the mobile gas measuring device, the additional gas measuring device and the central data processing unit in case of a determined limit value violation, taking into consideration weighted influencing variables;
• assign the hazard potential determined to the limit value violation;
• upon a first limit value violation and a second limit value violation being determined during a common time period or overlapping time periods, compare hazard potentials of the first limit value violation and of the second limit value violation to one another to determine a prioritization of limit value violations based on comparing hazard potentials;
• wherein the generation of the alarm control signals for the first limit value violation and for the second limit value violation are carried out based on the determined prioritization of limit value violations.

An alarm management system for managing alarms, the alarm management system comprising:

• mobile gas measuring devices carrying out gas concentration measurements in a monitored area;
• alarm triggering means for triggering alarms based on a determination of limit value violations caused by overshooting or undershooting of a limit value during the measurement of gas concentrations in the monitored area;
• and
• a central data processing unit configured to:
• determine a hazard potential for the limit value violations determined, wherein the hazard potential is based on the measurement and an analysis, taking into consideration weighted influencing variables;
• assign the determined hazard potential to the limit value violations;
• upon the limit value violations, including a first limit value violation and a second limit value violation, being determined during a common time period or overlapping time periods, comparing the hazard potential assigned to the first limit value violation and the hazard potential assigned to the second limit value violation to one another and determining a prioritization of the first limit value violation and the second limit value violation based on the comparison;
• and
• generate an alarm control signal, suitable for taking an action, for the first limit value violation and for the second limit value violation, wherein the alarm control signals are generated taking into consideration the determined prioritization.
