Building Security System False Alarm Reduction via Database Search
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Building security systems often experience false alarms due to faulty equipment, misconfiguration, or user behavior, which can be challenging to manage effectively.
Innovation Solution
A processing circuit in the security system detects false alarms and searches a database to identify past corrective actions. Based on the analysis, it generates and implements corrective actions to reduce the occurrence of false alarms by updating the operation of security equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If security systems trigger alarms when building data falls beyond valid range or indicates abnormal condition, then security monitoring capability is improved, but false alarm occurrence increases
Solution Approach 1:
The system performs preliminary actions by searching the database for past corrective actions and analyzing their effectiveness before implementing new corrective actions. This historical analysis allows the system to learn from previous experiences and make more accurate decisions, reducing false alarms while maintaining security monitoring capability.
Solution Approach 2:
The system implements feedback by using the database to store and retrieve information about past false alarms and corrective actions. The processing circuit analyzes the effectiveness of previously implemented corrective actions and uses this feedback to generate improved corrective actions, creating a closed-loop system that continuously reduces false alarm occurrence.
2Object-generated harmful factors
If corrective actions are implemented to reduce false alarms, then false alarm occurrence is reduced, but system complexity increases
Solution Approach 1:
The system performs self-service by automatically analyzing false alarm patterns, searching the database for relevant past corrective actions, and implementing corrective actions without requiring constant human intervention. The processing circuit autonomously manages the reduction of false alarms, reducing the operational complexity despite the added system components.
Solution Approach 2:
The system uses copying by retrieving and applying past corrective actions from the database that have been proven effective. Instead of developing entirely new corrective actions, the system copies and adapts proven solutions from historical data, simplifying the corrective action generation process while maintaining effectiveness.
3Measurement precision
If database search is performed to identify past corrective actions, then corrective action accuracy is improved, but processing time increases
Solution Approach 1:
The system applies partial action by searching for and implementing only the most relevant corrective actions from the database based on the specific false alarm pattern detected. Rather than analyzing all possible past corrective actions, the system focuses on the most pertinent ones, reducing processing time while maintaining high accuracy in corrective action selection.
Data Source
AI summary
A security system of a building includes a processing circuit. The processing circuit is configured to detect, based on data of security equipment of the building, that a security alarm of the building is a false alarm and search, responsive to the detection of the false alarm, a database to identify a past corrective action accepted for implementation and at least one false alarm occurring after the past corrective action was accepted and before detection of the false alarm. The processing circuits is configured to generate a corrective action to reduce an occurrence of the false alarm based on a result of the search and implement the corrective action to update operation of the security equipment to reduce the occurrence of the false alarm.
