Building Automation Device Identification via Network Response Probing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In IoT device networks, especially in building automation systems, device configuration and documentation often become incomplete or incorrect due to differing conventions among contractors and inadequate updates, leading to misconfiguration and inefficiencies in device management.
Innovation Solution
A method is introduced to discover and identify devices within a network by sending requests to obtain data values, identifying device types based on responses, and updating the device configuration in a data store, using building automation protocols to ensure accurate representation of device states and configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual configuration and documentation methods are used by multiple contractors, then device installation can be completed, but configuration accuracy and documentation completeness deteriorate due to differing conventions and inadequate updates
Solution Approach 1:
The system enables devices to self-identify and self-document by automatically transmitting identification data and configuration information to the central platform when they join the network, eliminating the need for manual configuration by contractors and ensuring accurate, standardized documentation from the outset
Solution Approach 2:
The system continuously monitors and updates device information by receiving feedback from devices about their operational status and configuration changes, automatically correcting documentation discrepancies and maintaining accurate device records without manual intervention
2Reliability
If manual configuration updates are performed when devices are replaced or reconfigured, then device information can be updated, but documentation completeness worsens due to inadequate updates and incorrect configurations
Solution Approach 1:
The system automatically detects when devices are replaced or reconfigured by monitoring network traffic and device identification data, then updates the documentation database in real-time to maintain complete and accurate device information without manual intervention
Solution Approach 2:
The system pre-configures device documentation templates and identification schemas before devices are installed, ensuring that all necessary information is captured automatically when devices join the network, preventing information gaps before they occur

AI summary
Discovering devices and device configurations. A method includes sending a request to a device to obtain a data value from the device. The method further includes, in response, receiving the data value from the device. The method further includes, based on the received data value, identifying one or more device identifications for the device. The method further includes, using the one or more identifications, sending commands for equipment potentially connected to the device. The method further includes, receiving one or more responses to the commands. The method further includes, based on the one or more responses, concretely identifying the device.
