Optical Sensor LED Status Indication in Fire Suppression Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire suppression systems lack effective mechanisms for visually indicating the status of optical sensors and interface modules, particularly in the event of faults or fire detection, which complicates troubleshooting and maintenance.
Innovation Solution
The system incorporates light-emitting devices (LEDs) to display different colors based on the status of optical sensors and interface modules, allowing for easy identification of normal operation, faults, and fire detection, with features like latching amber/yellow colors for intermittent faults and a reset button for troubleshooting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fire suppression systems use optical sensors to detect fire conditions, then fire detection capability is improved, but the system lacks visual indication mechanisms for sensor status and faults, making troubleshooting difficult
Solution Approach 1:
The patent applies color-changing LEDs to indicate different operational states of the fire suppression system. Green LEDs indicate normal operation, yellow LEDs indicate fault conditions, and red LEDs indicate fire detection. This visual color-coding system allows maintenance personnel to quickly identify system status and troubleshoot issues without complex diagnostic equipment, directly resolving the contradiction between reliable fire detection and ease of repair.
2Reliability
If the system continuously monitors sensor status for reliable operation, then system reliability is improved, but the complexity of the indication system increases
Solution Approach 1:
The patent segments the indication system into separate LED indicators for different operational aspects: power status, sensor status, fault conditions, and fire detection. Each aspect has its own dedicated LED, allowing continuous monitoring of multiple parameters simultaneously. This segmentation approach maintains high system reliability through comprehensive monitoring while keeping the indication system simple and intuitive through clear visual separation of different status types.
3Ease of repair
If the system provides detailed fault indication for each sensor, then ease of repair is improved, but the device complexity increases
Solution Approach 1:
The patent implements universal LED indicator modules that can indicate multiple types of status conditions using the same hardware components. The same LED indicators serve multiple functions: showing power status, sensor operational status, fault conditions, and fire detection. This multi-functionality approach provides detailed fault indication for each sensor, improving ease of repair, while avoiding increased device complexity by reusing the same indication hardware for multiple purposes.
