Building Sensor Aperture Adjustment for Precise Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The commissioning and configuration of building service systems, such as lighting systems, are time-consuming and lack precision in sensor-based control, often resulting in unnecessary illumination or uncovered spaces due to inadequate sensor positioning and coverage area management.
Innovation Solution
A method and system that automatically adjust the sensor aperture or opening angle of building service sensors based on their position relative to other sensors, allowing for precise control of sensor coverage areas to ensure mutual exclusivity or predetermined overlap, thereby improving precision and reducing uncovered spaces.

Engineering Contradiction Analysis
1Productivity
If manual commissioning and configuration of building service systems is performed, then system setup can be completed, but the process is time-consuming and requires specialized services
Solution Approach 1:
The system enables sensors to automatically determine their spatial positions through wireless communication and triangulation with reference nodes, and automatically adjusts sensor aperture angles based on relative positions, eliminating the need for manual commissioning by specialists
Solution Approach 2:
Reference nodes are pre-installed in the building space to establish a coordinate system beforehand, enabling sensors to automatically determine their positions and configure themselves without requiring manual setup during commissioning
2Measurement precision
If sensor coverage areas are not adjusted, then installation is simpler, but precision of sensor-based control deteriorates resulting in unnecessary illumination or uncovered spaces
Solution Approach 1:
The sensor aperture angle is made dynamically adjustable based on the sensor's spatial position relative to other sensors, allowing the coverage area to adapt automatically to achieve optimal precision while maintaining simple installation procedures
Solution Approach 2:
The system uses wireless communication between sensors to exchange position information and automatically adjusts aperture angles based on feedback from relative position data, achieving precise sensor control without manual configuration

AI summary
The invention relates to adjusting at least one of installed building service sensors (10) of a building service system. A sensor coverage area of at least one sensor (10) is adjusted based on information on a position of the installed sensor (10) relative to at least one other sensor (10). For example, to determine the position of the sensor (10) relative to said at least one other sensor (10), each sensor (10) establishes a wireless communication between said sensor (10) and at least one other sensor (10) via a wireless communication means (34) of the sensor (10). For example, information on the positions of the installed sensors (10) is used to assign to each sensor (10) at least one of installed building service supply devices (12) of the system.
