RFID Tag and Transceiver Wireless Fire Device Diagnostics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fire detection systems require time-consuming and costly periodic testing, diagnostic evaluations, and maintenance due to inaccessible connection ports and communication wires, necessitating physical removal of devices for diagnostic tool connection.
Innovation Solution
Incorporating a radio frequency identification (RFID) tag affixed to the base portion of each fire device, which uniquely identifies its location, and a transceiver at the device portion to enable wireless communication with a diagnostic tool for configuration, maintenance, and testing functions, allowing communication without powering the transceiver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connection is used to connect diagnostic tool to fire device, then reliable data transfer is achieved, but device must be removed from base making process time-consuming and costly
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system. The fire device includes a wireless transceiver that communicates with the diagnostic tool via wireless signals, eliminating the need for physical connection ports and wires. This allows the device to remain installed on the base while enabling data transfer and diagnostic functions.
Solution Approach 2:
The patent introduces an RFID tag as an intermediary component between the fire device and the diagnostic tool. The RFID tag is affixed to the base portion and contains identification information, allowing the diagnostic tool to wirelessly identify and communicate with the specific fire device without requiring physical access to connection ports.
2Ease of repair
If connection port is made accessible for diagnostic tool connection, then ease of maintenance is improved, but device security and protection from tampering worsens
Solution Approach 1:
The patent replaces the physical connection port with a wireless communication interface. The transceiver communicates with the diagnostic tool through wireless signals, eliminating exposed connection ports that could be accessed or tampered with. This maintains device security while enabling maintenance functions.
Solution Approach 2:
The patent extracts the communication function from the physical device body by using a separate RFID tag and wireless transceiver system. The RFID tag is affixed to the base portion while the transceiver is in the device portion, separating identification and communication functions from the main device structure, reducing tampering risks.
3Adaptability or versatility
If RFID tag is affixed to base portion instead of device portion, then device replacement flexibility is improved, but communication reliability during replacement worsens
Solution Approach 1:
The patent divides the fire device into two segments: a replaceable device portion containing the transceiver and a fixed base portion containing the RFID tag. This segmentation allows the device portion to be easily replaced while the base portion with the identification tag remains in place, maintaining system continuity.
Solution Approach 2:
The RFID tag is pre-affixed to the base portion before device replacement occurs. This preliminary placement ensures that when a new device portion is installed, the communication between the transceiver and RFID tag is immediately established without requiring reconfiguration or reattachment of identification components.

AI summary
A method of operating a fire detection system includes arranging one or more fire devices. Each fire device includes a base portion fixed in a location and a replaceable device portion installed to the base portion. The device portion is configured to detect fire and/or smoke or to perform other fire detection system functions. A radio frequency identification (RFID) tag is affixed to the base portion or to the replaceable device portion. The RFID tag uniquely identifies a location of the fire device. A transceiver is located at the device portion to receive a signal from the RFID tag. A diagnostic tool wirelessly communicates with the fire device through the transceiver.
