Control Bus Address Assignment via Counter Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for assigning addresses to electronic devices connected to a control bus are time-consuming, especially in large buildings with numerous devices, as they require manual searching for activated components.
Innovation Solution
A control unit comprising a base device and a mobile device, each equipped with a counting device, which alternately switches on and off all devices on the bus, allowing the mobile device to store counter readings at trigger events, enabling efficient assignment of addresses by comparing readings.

Engineering Contradiction Analysis
1Measurement precision
If manual searching for switched-on lighting components is used to identify device addresses, then the assignment can be completed, but the time expenditure increases considerably with increasing number of devices and building size
Solution Approach 1:
The patent replaces the manual mechanical search process with an automated optical/electronic system. The mobile device uses a light sensor to detect which lighting component is currently switched on, automatically identifying its address without requiring manual searching. This substitutes human physical movement and visual search with automated photodetection and digital address recognition.
Solution Approach 2:
The system enables self-service address assignment where the lighting components themselves provide identification information. When a lighting component is switched on, it automatically emits light that the mobile device detects, and the system automatically records the address assignment without requiring user intervention to search or identify the component.
2Productivity
If the control unit uses automated counting devices and light detection to identify device addresses, then the address assignment time is significantly reduced, but the device complexity increases
Solution Approach 1:
The mobile device performs multiple functions: it serves as a user interface, a light detection sensor, a counting device, and a data storage unit. By combining these functions into a single handheld device, the system achieves automated address assignment without requiring separate specialized equipment for each function, thereby limiting the increase in overall system complexity.
Solution Approach 2:
The system uses changes in light parameters (presence/absence of light from switched-on components) to trigger address identification. The mobile device detects light intensity changes and automatically correlates them with address sequences, using physical parameter changes rather than complex mechanical or manual procedures to achieve rapid assignment.

AI summary
The invention relates to a control unit (101) connectable to a control bus (1). Electronic devices (G1, G2, G3, G4, G5) connected to the control bus (1) can each be controlled via the control bus using a unique address (A1, A2, ..., A4, A5, ..., A9, ...). The control unit (101) consists of a base unit (102) connectable to the control bus (1) with a base unit counter (102') and a mobile unit (103) with a mobile unit counter (103'). The counters (102', 103') begin to count at a stable, defined rate, and the base unit (102) transmits a switch-on/switch-off command to each address (A1, A2, ..., A4, A5, ... A9, ...) and subsequently a switch-off/switch-on command to each address in sequence, and assigns to each address (A1, A2, ..., A4, A5, ... A9, ...) the counter value of the base unit counter (102') at the respective switch-off/switch-on time.Upon receiving a trigger command, the mobile device (103) stores the current meter reading of the mobile device's metering device (103') at the time of the trigger command. The stored meter readings are then compared with the meter readings stored in the base unit (102) so that the addresses of the control bus (1) can be assigned to the electronic devices (G1, G2, G3, G4, G5).
