Fire Alarm Detector with Webserver Email Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire alarm systems often struggle to accurately detect and report small or deep-seated fires within structures, as central monitoring stations may not receive timely or reliable information, leading to potential delays in response.
Innovation Solution
A fire alarm system with interconnected environmental condition detectors and a local alarm panel, where each detector includes a sensor element and reporting processor that sends independent alarm messages to users via the Internet or cellular networks when predefined threshold values are exceeded, allowing for real-time monitoring and flexible reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a central monitoring station is used to monitor fire alarms, then centralized control and coordination are improved, but response time to small or deep-seated fires deteriorates due to communication delays and contact verification requirements
Solution Approach 1:
The system divides the monitoring function into two independent paths: centralized monitoring through the control panel and direct notification to occupants via the web server and email system. This segmentation allows the centralized control to maintain coordination while the direct notification path eliminates communication delays for immediate alerting.
Solution Approach 2:
The web server acts as an intermediary between the sensor detector and the occupant, providing a direct communication channel that bypasses the traditional centralized monitoring station contact verification process. This intermediary enables immediate notification while the control panel continues its centralized coordination function.
2Reliability
If central monitoring stations attempt to contact occupants to confirm fire presence, then verification accuracy is improved, but time loss due to contact attempts and potential dispatch of security personnel increases
Solution Approach 1:
The system performs preliminary notification by directly alerting occupants through email and web server before any verification contact is attempted. This preliminary action ensures occupants are immediately aware of the alarm condition, eliminating the time lost in back-and-forth verification attempts while maintaining reliability through the control panel's continued verification process.
3Ease of manufacture
If standalone sensor detectors are used, then simplicity and ease of installation are improved, but monitoring coverage and coordinated response capability deteriorate
Solution Approach 1:
The sensor detector is designed with multi-functionality, serving both as a standalone unit with direct web server and email notification capabilities and as an integrated component of the centralized control panel system. This universality allows the detector to provide comprehensive monitoring coverage when installed with the control panel while maintaining ease of installation as a standalone unit.
Data Source
AI summary
A detector is described. The detector includes one or more environmental sensors that measures a predetermined environmental parameter, a processor that compares the measured parameter with a plurality of threshold values and detects that the measured parameter exceeds one of the plurality of threshold values and constructs a message to a person associated with the exceeded threshold value and an Internet protocol network interface that forwards the constructed message to the person.
