Security Control System with Multi-State Intrusion Detection Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security systems often generate high false alarm rates due to the lack of intelligent intrusion detection, leading to costly and disruptive responses from law enforcement.
Innovation Solution
A control system with multiple sensors that communicate sensor notifications to a processor, which compares these notifications to detection conditions to determine specific detection states and associated responses, reducing false alarms by providing a more intelligent level of intrusion detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the control panel generates an alarm when any one sensor is triggered, then intrusion detection capability is improved, but false alarm rate increases
Solution Approach 1:
The alarm system segments the detection logic into multiple detection states (e.g., potential intrusion state, confirmed intrusion state) rather than treating all sensor triggers uniformly. Each state has specific entry conditions and exit conditions, allowing the system to differentiate between genuine intrusions and false alarm sources by requiring specific patterns of sensor activations.
Solution Approach 2:
The system performs preliminary assessment by entering a potential intrusion state when sensors are triggered, rather than immediately generating an alarm. This preliminary state allows for additional verification through monitoring sensor patterns over time, and the alarm is only generated when the intrusion is confirmed through predefined criteria, thus reducing false alarms while maintaining detection capability.
2Measurement precision
If multiple detection states and responses are implemented, then false alarm reduction is improved, but system complexity increases
Solution Approach 1:
The complex detection logic is segmented into discrete, manageable detection states with clearly defined entry and exit conditions. Each state represents a specific stage in the intrusion assessment process, making the system's behavior predictable and easier to program, configure, and maintain despite the multiple states involved.
Solution Approach 2:
The system dynamically transitions between detection states based on real-time sensor inputs and predefined conditions. This dynamic state machine approach allows the system to adapt its response to different sensor patterns without requiring complex static logic, as the state transitions automatically handle the decision-making process based on current conditions.
