Security System Communication Loss Detection via Redundant Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current home security and automation systems require separate programming and control, limiting flexibility and versatility, and are prone to failure as a single point of vulnerability, with no effective mechanism for reporting communication loss or zone fault events to users and central stations.
Innovation Solution
A server-based system that monitors and reports status changes, including loss of communication with a security, monitoring, and automation (SMA) controller, sending notifications to users and central stations in case of communication failure or zone fault events, utilizing multiple network connections and timers to ensure reliable alarm reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single centralized controller is used for security, monitoring and automation, then device complexity is reduced, but reliability deteriorates due to single point of failure
Solution Approach 1:
The patent divides the centralized controller into multiple distributed controllers (first controller and second controller). Each controller can independently monitor and control security, monitoring, and automation functions. This segmentation eliminates the single point of failure while maintaining system functionality through distributed architecture.
Solution Approach 2:
The patent assigns different communication interfaces to different controllers (first controller with first interface, second controller with second interface). This allows local optimization of communication paths and enables independent operation of each controller through its own communication channel, improving overall system reliability.
2Ease of manufacture
If wireless protocols are used for security sensors, then ease of installation is improved, but loss of information increases due to communication failures
Solution Approach 1:
The patent implements a feedback mechanism where controllers continuously monitor communication status with wireless sensors. When communication failure is detected, the system generates notifications to alert users and central stations, ensuring that information loss is detected and communicated rather than silently occurring.
Solution Approach 2:
The patent establishes communication monitoring and failure detection mechanisms in advance. Delay timers and notification systems are pre-configured to detect and report communication failures before they result in complete information loss, allowing proactive response to potential issues.
3Reliability
If delay timers are used for alarm reporting, then reliability is improved by preventing false alarms, but loss of time increases due to delayed notification
Solution Approach 1:
The patent uses delay timers selectively rather than for all alarm conditions. The delay mechanism is applied only when communication failures are detected, while other alarm conditions trigger immediate notifications. This partial application of delay timing prevents false alarms from communication issues while maintaining rapid response for genuine threats.
Data Source
AI summary
Methods and systems for monitoring a premises are described. A server external to the premises may be in communication with a system at the premises. The server may receive status data from the system from one or more interfaces. If a loss of communication occurs on one interface, then the status data may be received via a second interface. The server may determine timing information for status data received via the first interface and for status data received via the second interface. The server may send, based on the timing information, a message to a computing device indicating the loss of communication.
