Automated Device Addressing via Indoor Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual installation and commissioning of building automation devices, such as HVAC and security systems, often result in errors due to the lack of easy methods to verify correct physical device address matching with intended designs, leading to complex troubleshooting processes.
Innovation Solution
A leveraged indoor positioning system that uses a mobile device with a position indicator and a building information model to automatically generate and assign unique physical addresses to devices based on their locations, eliminating manual steps and enabling automated configuration by correlating physical locations with network MAC addresses and storing this information for later use during commissioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual installation and commissioning methods are used, then installers can physically install devices using wiring diagrams, but errors occur in matching physical device addresses with logical device addresses leading to complex troubleshooting
Solution Approach 1:
The patent replaces manual mechanical address assignment methods with an automated optical scanning system. The installer uses a mobile device with a camera to scan QR codes on devices, automatically capturing and storing the correspondence between physical device locations and logical device addresses in a database, thereby eliminating manual errors and simplifying troubleshooting
Solution Approach 2:
The system enables self-service by allowing the mobile device to automatically capture device information through QR code scanning and autonomously store the mapping data in the database without requiring manual intervention for address assignment and recording
2Productivity
If manual address assignment is used, then installers can configure devices, but the process is time-consuming and error-prone
Solution Approach 1:
The patent replaces manual address assignment and data entry processes with automated optical scanning and digital database storage. The mobile device captures QR codes containing device information and automatically stores the mapping data, eliminating manual errors and significantly improving installation speed and configuration accuracy
Solution Approach 2:
The system uses QR codes as digital copies of device identification information. Instead of manually reading and transcribing device addresses, the mobile device scans the QR code to automatically capture and store the device's logical address and physical location mapping, ensuring accuracy and improving efficiency

AI summary
A leveraged positioning system for installation of devices within campuses and buildings. A mobile device may have a position indicator associated with it. A campus or building information model may be available for reference relative to a location of the mobile device as noted by the position indicator. A location name may be derived from the model and used for an installed device since the mobile device is at the position of the installed device during placement of the installed device. A physical address may be assigned to the installed device. The physical address and the location name may be stored as a pair in memory for the device. Additional devices for installation may be treated similarly.
