Fire Safety Device Commissioning Across Wired and Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of individually commissioning multiple fire safety devices via wireless communication networks is cumbersome and time-consuming, especially in large structures.
Innovation Solution
A method and system that utilize a controller to facilitate simultaneous commissioning of safety devices through a combination of hardwired and wireless communication networks, enabling the transmission of commissioning data packets to multiple devices via a hardwired network, and logging operational data for storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If safety devices are commissioned individually via wireless communication networks, then each device can be communicably coupled to the network, but the commissioning process becomes long and cumbersome
Solution Approach 1:
The patent combines multiple commissioning operations into a single unified process. A controller receives commissioning data at one safety device and automatically distributes it to all other safety devices through the communication network, merging individual commissioning tasks into one collective action that significantly reduces total commissioning time
Solution Approach 2:
The system performs preliminary actions by pre-configuring commissioning data at a single device before network distribution. The controller prepares and validates commissioning information in advance, then propagates it across the network, eliminating the need for repeated configuration steps at each device
2Reliability
If safety devices are commissioned individually, then each device can be authenticated and configured, but the overall commissioning process becomes complex and cumbersome
Solution Approach 1:
The controller serves as an intermediary between the commissioning source and all safety devices. It receives commissioning data, performs authentication and validation, then automatically distributes configured data to all devices, simplifying the process by centralizing complex authentication and configuration tasks in one intermediary component
Solution Approach 2:
The controller performs multiple functions: receiving commissioning data, authenticating devices, validating configuration, and distributing data across the network. This multi-functional approach consolidates what would otherwise require separate operations at each device into a single universal commissioning process
Data Source
AI summary
A system and method for commissioning safety devices is disclosed. The method includes providing one or more safety devices configured to generate a signal responsive to detection of a hazard. The one or more safety devices are communicably coupled to each other via first and second communication networks. The method further includes receiving, by a controller, at any one of the one or more safety devices, a first data packet including attributes pertaining to commissioning of the one safety device. The method further includes transmitting, by the controller, the first data packet to the remaining safety devices of the one or more safety devices through the first communication network. The method further includes receiving, by the remaining safety devices of the one or more safety devices, the first data packet to enable respective commissioning of the remaining safety devices.
