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 and resource wastage, as they lack dynamic priority adjustment mechanisms to differentiate between genuine and false alarms.
Innovation Solution
A dynamic alarm priority system that includes alarm devices, image capture devices, an interface device, and an object detection device, which captures images upon alarm triggers, assigns initial priorities based on time, and dynamically modifies these priorities based on object detection results using machine learning or deep learning techniques to prioritize true alarms over false ones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If alarm signals are processed in order of time receipt, then the system is simple to implement, but true alarms may be missed when false alarms are frequent
Solution Approach 1:
The patent implements dynamic priority adjustment where the assignment device continuously modifies alarm signal priorities based on real-time object detection results. When an object is detected in an alarm image, the priority of that alarm signal is dynamically increased to be processed first, while other alarm signals have their priorities adjusted accordingly. This dynamic mechanism resolves the contradiction by enabling reliable true alarm processing without requiring complex static priority rules.
Solution Approach 2:
The system establishes a feedback loop where object detection results are fed back to the assignment device, which then adjusts alarm signal priorities accordingly. The detection device provides feedback information about detected objects to the assignment device, creating a closed-loop system that continuously optimizes alarm processing based on actual detection conditions, thereby improving reliability while maintaining manageable complexity.
2Measurement precision
If the trigger threshold is set low to detect all alarms, then detection sensitivity is improved, but false alarms increase and waste resources
Solution Approach 1:
The patent applies local quality by differentiating the handling of different alarm signals based on their specific characteristics. Instead of uniformly processing all alarms with the same priority, the system assigns different processing priorities to different alarm signals based on object detection results. Alarm signals associated with detected objects receive higher priority, while those without detected objects are deferred, thereby reducing resource wastage on false alarms while maintaining high detection sensitivity.
Solution Approach 2:
The system dynamically changes the priority parameter of alarm signals based on object detection results. When an object is detected in an alarm image, the priority parameter of that alarm signal is changed to indicate it should be processed first. This parameter change mechanism allows the system to maintain low trigger thresholds for high sensitivity while avoiding resource wastage by prioritizing only those alarms that appear to be true based on object detection.
3Speed
If multiple alarm signals are processed simultaneously, then response time is reduced, but processing accuracy decreases due to false alarms
Solution Approach 1:
The patent segments the alarm signal processing into distinct priority levels based on object detection results. Alarm signals are segmented into high-priority queue (for alarms with detected objects) and low-priority queue (for alarms without detected objects). This segmentation allows the system to process true alarms quickly while deferring false alarms, thereby maintaining both processing speed and accuracy by handling different alarm types through separate processing paths.

AI summary
A dynamic alarm priority system includes plural kinds of alarm devices (11A, 11B, 11C), an alarm signal being generated when the alarm device is triggered; a plurality of image capture devices (12), 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 (13) that receives the alarm signal; an assignment device (14) 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 (15) 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.
