Alarm Triggering Time Determination Using Continuous Waiting Function
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas alarm systems face challenges in determining alarm triggering times for variable gas concentrations, leading to discontinuities and potential delays or false alarms, as different standards require specific waiting times based on measured values, which can result in abrupt changes in required alarm issuance times.
Innovation Solution
A method using a continuous function to determine waiting times for alarm issuance, ensuring no jumps or discontinuities, allowing for reliable triggering time calculation even with changing measured values, and adaptable to meet various legal standards by adjusting function parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different waiting times are assigned to different measured value ranges according to standards, then alarm issuance compliance with standards is improved, but discontinuities and jumps in alarm triggering time occur
Solution Approach 1:
The patent applies parameter changes by continuously adjusting the waiting time parameter as a function of the measured value, rather than using fixed discrete waiting times. This allows the system to meet standard compliance requirements while maintaining continuous variation in alarm triggering time, eliminating jumps and discontinuities through mathematical function-based parameter transformation.
Solution Approach 2:
The invention implements dynamics by making the waiting time dynamic and continuously adaptable to the current measured value through a continuous function. Instead of static waiting time assignments, the system dynamically calculates the appropriate waiting time based on real-time sensor readings, enabling smooth transitions and eliminating abrupt changes in alarm triggering behavior.
2Loss of time
If alarm triggering time is determined based on current measured value, then early alarm issuance is improved, but ambiguity and false alarms occur due to variable concentrations
Solution Approach 1:
The patent applies preliminary action by continuously calculating the alarm triggering time in advance based on the current measured value and the continuous function. This allows the system to determine the exact moment when an alarm should be issued, enabling early alarm issuance while maintaining accuracy through continuous mathematical evaluation rather than discrete threshold comparisons.
Solution Approach 2:
The invention implements feedback by continuously monitoring the measured value and using it to dynamically adjust the waiting time through the continuous function. This feedback mechanism ensures that the alarm triggering time is always optimally determined based on current conditions, preventing both premature and delayed alarms while eliminating ambiguity through continuous rather than discrete evaluation.

AI summary
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.
