Solution Approach 1:

The system automatically adjusts proximity thresholds by monitoring signal strength values and detecting when they exceed predefined thresholds. The control unit autonomously updates threshold values based on received signal characteristics without requiring manual user intervention, thereby maintaining detection accuracy while eliminating the complexity of manual adjustment.

Inventive Principle:

Solution Approach 2:

The system continuously monitors received signal strength values and uses this feedback to dynamically adjust proximity thresholds. When signal strength exceeds a threshold, the system updates the threshold value based on the measured signal characteristics, creating a closed-loop control system that adapts to changing environmental conditions automatically.

Solution Approach 1:

The control unit automatically adapts to different lighting nodes by monitoring their specific signal characteristics and adjusting thresholds individually based on each node's emission properties. This self-service adaptation mechanism enables the system to handle diverse lighting nodes without requiring complex manual configuration for each device.

Inventive Principle:

Solution Approach 2:

The system applies different threshold values and update criteria specific to each lighting node based on its individual signal characteristics. By customizing threshold parameters locally for each node rather than using a universal threshold, the system achieves high adaptability while keeping the adjustment logic relatively simple and node-specific.

Solution Approach 2:

The system transitions from static, manually-configured thresholds to dynamic, automatically-adjusted thresholds that adapt in real-time based on signal conditions. This dynamic approach improves operational efficiency by enabling the system to respond automatically to changing environments, while the automation of the adjustment process prevents complexity from becoming unmanageable.

AI summary

The invention is directed to a proximity-detecting device configured to determine a signal-strength value (S) indicative of a received signal power amount of an identification signal of an originating lighting node that comprises lighting-node identification information and that is received via a signal input unit (102). It also comprises a proximity-detection unit (106) configured, upon determining that the received signal-strength value exceeds a predetermined proximity threshold value (Sth), to generate and provide a proximity-information signal (P) indicative of the proximity-detecting device being within a proximity area. It also comprises a threshold-determination unit (108) configured, upon determining fulfilment of a pre-stored threshold-updating criterion (C) comprising one or more updating-conditions associated with the lighting-node identification information, to update the proximity threshold value for the given originating lighting node, for redefining the adaptation.
