Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual process of matching device IDs in lighting control systems is time-consuming and prone to errors, requiring engineers to read barcodes and enter IDs manually, which is inefficient and error-prone, especially when establishing multiple reference points for automated commissioning in wireless networks.
Innovation Solution
A method that automatically establishes reference nodes in a wireless network by analyzing unique device types and range measurements between devices, eliminating the need for manual barcode reading and ID entry, using a computer program to store IDs and coordinates in a database, allowing for automated commissioning without initial manual setup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual barcode reading and ID entry is used to establish reference nodes, then device identification can be completed, but the commissioning process becomes time-consuming and error-prone
Solution Approach 1:
The system performs automatic self-identification by having devices broadcast their unique IDs and allowing the commissioning system to automatically capture and match these IDs with building plan records, eliminating the need for manual barcode reading and ID entry while maintaining accuracy
Solution Approach 2:
The manual mechanical process of reading barcodes and entering IDs is replaced with an automated electronic system that uses wireless communication to automatically detect, capture, and match device IDs, significantly reducing commissioning time and errors
2Measurement precision
If multiple reference points are established to improve positioning accuracy, then triangulation precision increases, but the complexity and time required for establishing reference points increases
Solution Approach 1:
The system automatically performs the preliminary action of selecting and establishing optimal reference nodes based on device distribution and signal characteristics, eliminating the need for manual selection and reducing the complexity of establishing multiple reference points while maintaining positioning accuracy
Solution Approach 2:
The commissioning system uses feedback from signal strength measurements and device distribution analysis to automatically determine the optimal number and locations of reference nodes, dynamically adjusting the reference point establishment process to achieve required precision without unnecessary complexity

AI summary
A method for matching an actual device in a wireless network to a corresponding device indicated in a plan (1) of such devices is provided. The method is suitable for initiating the commissioning process for a lighting control network (2) or an automated home network and it enables the program controlling the system to establish a number of reference nodes, with respect to which the coordinates of the rest of the nodes in the network are established, without the engineer having to manually enter the identification details of the reference nodes in the computer system. The method comprises identifying a device (3a-3c, 4, 5a-5b, 6a-6c, 7a-7d, 8a-8f, 9a-9f, 10, 11b, 11b) in the plan having unique characteristics compared to the other devices in the plan (1); receiving data comprising the characteristics of the actual device from the wireless network; and in response to the characteristics of the actual device including the unique characteristics, matching the physical device with the identified device. The unique characteristics may comprise a unique type or a unique range measurement to another device. The received data includes the unique ID (101-115) of the actual device and this can be stored in a record for the identified device in the computer system.
