Lighting Control Bus Localization via Electrical Parameter Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting control systems require manual commissioning by trained technicians to localize devices, which is inefficient and limits the ability to detect device positions without external activation.
Innovation Solution
A method for automatic localization of bus communication participants in a lighting control system using electrical parameter matching, involving determining planned and observed electrical parameters on a lighting control bus, establishing different states of power transfer, and matching these parameters to identify device positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual localization by trained technicians is used, then device position can be identified, but system setup time increases and productivity decreases
Solution Approach 1:
The system performs automatic localization without requiring trained technicians. Each bus communication participant automatically detects electrical parameters, compares them with planned parameters from the electrical layout plan, and identifies its own position. This self-service approach eliminates manual commissioning while maintaining accurate device position identification.
Solution Approach 2:
The electrical layout plan is created beforehand with planned electrical parameters for each device position. During automatic localization, the system compares currently detected electrical parameters against these pre-stored planned parameters to identify device positions, eliminating the need for real-time manual measurement and technician intervention.
2Adaptability or versatility
If devices require external activation for localization, then device complexity remains low, but adaptability decreases as devices without outside access cannot be localized
Solution Approach 1:
The electrical parameters detection mechanism serves multiple functions: it is used both for normal device operation monitoring and for automatic localization. Each bus communication participant uses its existing electrical parameter detection capability to perform localization by comparing detected parameters with planned parameters from the electrical layout plan, eliminating the need for separate localization hardware or external activation mechanisms.

AI summary
Disclosed is a method (1) for automatic localization of a number of N bus communication participants (2) of a lighting control bus (5). The method (1) comprises determining (12), for each of the number of N bus communication participants and for at least N different states of power transfer on the lighting control bus (5), respective planned electrical parameters (Vn,p―Vn,0) on the lighting control bus (5) in accordance with an electrical layout plan of the lighting control bus (5); establishing (13) the at least N different states of power transfer on the lighting control bus (5); detecting (14), by each of the number of N bus communication participants in each of the at least N different established states of power transfer on the lighting control bus (5), a respective observed electrical parameter (Vn―Vn,0) on the lighting control bus (5); and matching (15), for each of the at least N different established states of power transfer on the lighting control bus (5), the respective planned electrical parameters (Vn,p―Vn,0) on the lighting control bus (5) with the respective observed electrical parameters (Vn―Vn,0) on the lighting control bus (5). This avoids the necessity of having a trained service technician on-site during commissioning of a lighting system.
