Sensor Alarm Communication with Swinger Count Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensor communication systems experience increased network traffic and reduced battery life due to repeated transmission of alarm messages for the same event, leading to delayed message delivery and inefficient resource utilization.
Innovation Solution
Implementing a controller in sensors that counts alarm messages and stops transmission after reaching a predefined swinger count, reducing redundant messages and optimizing communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sensor repeatedly transmits alarm messages for the same event, then the alarm detection reliability is improved, but the network traffic increases and battery life decreases
Solution Approach 1:
The system performs preliminary action by sending an alarm message immediately when an event is detected, ensuring reliable alarm detection. The swinger count mechanism then prevents redundant transmissions by monitoring how many times the same alarm has already been sent, stopping further transmissions once the threshold is reached. This resolves the contradiction by ensuring the alarm is detected reliably while preventing excessive energy consumption from repeated messages.
2Reliability
If the sensor repeatedly transmits alarm messages for the same event, then the alarm detection reliability is improved, but the network traffic increases
Solution Approach 1:
The alarm message is sent immediately when the event is detected, ensuring reliable detection. The control panel then monitors the swinger count to determine if additional alarm messages should be suppressed, preventing excessive network traffic while maintaining alarm reliability.
3Speed
If the sensor transmits alarm messages for every sensed event, then the response time is improved, but the message delivery efficiency decreases
Solution Approach 1:
Alarm messages are transmitted immediately upon detecting sensed events, ensuring fast response time. The swinger count mechanism then prevents network congestion by suppressing redundant alarm messages for the same event, maintaining message delivery efficiency. This resolves the contradiction by ensuring urgent alarms are delivered quickly while preventing network overload from excessive transmissions.

AI summary
A method for and system for controlling a building monitoring system including a sensor assembly. The sensor assembly includes a sense element for detecting sensed events in a space, a communication port, and a controller operatively coupled to the sense element and the communication port. The controller is configured to receive from the sense element an indication of a sensed event occurring in the space, transmit an alarm message pertaining to the detected sensed event via the communication port, and after transmitting the alarm message pertaining to the detected sensed event, receive from the sense element an indication of a plurality of subsequent sensed events occurring in the space until a number of transmitted alarm messages reaches a swinger count. When the number of transmitted alarm messages reaches the swinger count, stop transmitting an alarm message for each of the plurality of subsequent sensed events.
