Dynamic Alarm Priority System Using Object Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional alarm systems face inefficiencies due to high false alarm rates, which can lead to missed true alarms as they prioritize and process signals based solely on time, wasting resources and delaying critical responses.
Innovation Solution
A dynamic alarm priority system that includes image capture devices, an interface device, an assignment device, and an object detection device, which captures images upon alarm triggers, determines the presence of objects, and dynamically adjusts signal priorities to ensure true alarms are processed first and false alarms are deferred.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If alarm signals are processed in order of time received, then the processing order is simple and systematic, but true alarms may be delayed due to false alarms occupying processing resources
Solution Approach 1:
The system performs preliminary object detection on alarm images before final processing. Image capture devices capture images when alarms are triggered, and object detection devices analyze these images in advance to determine if they represent true alarms. This preliminary detection allows the system to identify true alarms before the main processing queue, ensuring they are not delayed by false alarms while maintaining systematic processing for other signals.
2Reliability
If the trigger threshold is low, then the alarm system is sensitive to all potential threats, but false alarms increase and waste processing resources
Solution Approach 1:
The system introduces image capture devices and object detection devices as intermediaries between the alarm trigger and the processing queue. When an alarm is triggered, the associated image capture device captures an image, and the object detection device analyzes it to verify if a true threat exists. This intermediary verification process filters out false alarms before they enter the main processing queue, allowing the system to maintain low trigger thresholds for sensitivity while preventing false alarms from consuming processing resources.
3Measurement precision
If image capture and object detection are performed for all alarm signals, then true alarm accuracy is improved, but system complexity and processing time increase
Solution Approach 1:
The system applies image capture and object detection selectively rather than uniformly to all alarm signals. Each alarm device has an associated image capture device, but the object detection processing is prioritized based on the alarm queue position and preliminary assessments. True alarms detected through object detection are processed immediately with high priority, while other alarms follow the standard queue. This local application of verification resources improves accuracy for critical cases without unnecessarily increasing system complexity for all signals.

AI summary
A dynamic alarm priority system includes plural kinds of alarm devices, an alarm signal being generated when the alarm device is triggered; a plurality of image capture devices, correspondingly coupled to the alarm devices respectively, the triggered alarm device activating the corresponding image capture device to capture an alarm image; an interface device that receives the alarm signal; an assignment device coupled to receive the alarm signals, which are assigned priorities in order of time, thereby generating an initial alarm signal sequence; and an object detection device that performs object detection on the alarm image to determine whether an associated object is detected in the alarm image. The assignment device dynamically modifies the initial alarm signal sequence according to an object detection result from the object detection device, thereby generating an updated alarm signal sequence.
