Determination of an alarm-issuing time of an alarm device
First Claim
1. A method for determining a triggering time for issuing an alarm of an alarm device, the method which comprises:
- detecting a measured value at a measuring time, the measured value being indicative of a hazard potential within a monitoring range;
establishing a waiting time by way of a function based on a given standard, the function;
specifying an assigned waiting time in each case for a plurality of different measured values, the waiting time reducing as the measured value rises and increasing as the measured value falls, for a slight increase in the measured value, the corresponding waiting time also only changes slightly; and
having a continuous profile, the continuous profile not exhibiting jumps or discontinuities;
determining the triggering time based on the measuring time and the waiting time thus established; and
the waiting time being the time necessary to wait after the occurrence of the measured value before an alarm may be issued; and
covering extended alarm issuing ranges, the extended alarm issuing ranges resulting in the alarm being issued more quickly than if the alarm issuing conditions predetermined by the standard are used for issuing the alarm.

Abstract
A method for determining a triggering time for the issuance of an alarm by an alarm device. A measured value is sensed at a measuring time, and the measured value is indicative of a hazard potential within a monitoring range. A waiting time is identified by way of a function which respectively indicates an assigned waiting time for a plurality of different measured values and which has a continuous profile. The triggering time is determined on the basis of the measuring time and the identified waiting time. In addition, an alarm device having a detection device for sensing a measured value and having an evaluation device which is configured to carry out said method is described. In addition, a program element for determining a triggering time for the issuance of an alarm by an alarm device is described, wherein the program element can be loaded into an evaluation unit of the alarm device and can cause the abovementioned method to be carried out.

15. A method for determining a triggering time for issuing an alarm of an alarm device, the method which comprises:
-
detecting a measured value at a measuring time, the measured value being indicative of a hazard potential within a monitoring range; establishing a waiting time by way of a function, the function; specifying an assigned waiting time in each case for a plurality of different measured values, the waiting time reducing as the measured value rises and increasing as the measured value falls, for a slight increase in the measured value, the corresponding waiting time also only changes slightly; and having a continuous profile, the continuous profile not exhibiting jumps or discontinuities; determining the triggering time based on the measuring time and the waiting time thus established; the waiting time being the time necessary to wait after the occurrence of the measured value before an alarm may be issued; and defining the function so as not to fall below a waiting-time-independent minimum threshold for the measured value, the waiting time-independent minimum threshold value represents an absolute lower boundary for the measured value below which the alarm may not be issued.
