Addressable Node Unit Power Management via Switching and Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing addressable node units face challenges in receiving digital addressing signals and maintaining power supply during idle states, especially in branched lines, which complicates digital transmission and requires additional measures.
Innovation Solution
The node unit incorporates a power storage device, preferably a capacitor, and a switchover unit to reduce current consumption, ensuring the evaluating circuit is powered even when the first node unit is cut off from the power supply, allowing for efficient digital addressing and fast addressing methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the first node unit is cut off from the power supply line to enable addressing of the next node unit, then the addressing signal can be passed to the next node unit, but the evaluating circuit of the first node unit loses power supply
Solution Approach 1:
The power storage device is charged in advance during the period when the node unit is being addressed, so that it can supply power to the evaluating circuit during the idle period when the node unit is cut off from the power supply line for addressing the next node unit
Solution Approach 2:
The power storage device acts as an intermediary between the power supply line and the evaluating circuit, decoupling the power supply from the addressing signal path and ensuring continuous power availability to the evaluating circuit regardless of the addressing state
2Reliability
If additional power storage devices and switchover units are added to ensure continuous power supply, then power reliability is improved, but device complexity increases
Solution Approach 1:
The power storage function is extracted from the main power supply line and implemented as a separate, simple power storage device (capacitor or battery) that can be easily integrated into the node unit circuit
Solution Approach 2:
The power storage device automatically charges and discharges based on the operational state of the node unit, requiring no external control or complex management circuitry - the system serves itself through the natural charge/discharge cycles of the storage device

AI summary
An addressable node unit (30) has connections (15a, 15b, 16) for at least two lines (17, 18a, 18b) via which the node unit (30) can be addressed. The connections (15a, 15b, 16) are connected to a circuit (14) which evaluates an addressing signal. The node unit (30) has at least one power source (4, 22) which can be supplied with power via at least one of the lines (17, 18a, 18b). A switch (25) is provided in the path between the evaluating circuit (14) and the corresponding line connection (15a, 15b), said switch (25) has to be opened after an addressing process so that the power supply of the evaluating circuit (14) is ensured by the at least one power source (4, 22) after the addressing.
