Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for managing and monitoring arrays of electrochemical converters, such as accumulators, face challenges in accurately assigning measurement signals and switching signals to the correct components, especially as accumulators age unevenly, leading to potential errors in data collection and unreliable monitoring.
Innovation Solution
A method using unique identification features and a measuring arrangement with sensors attached to electrochemical converters to determine their spatial and electrical arrangement, allowing for reliable and automated assignment of measurement sensors, even after changes or maintenance, by utilizing serial numbers, data transmission times, and reception times to create a precise image of the array configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual assignment methods are used to assign measurement sensors to accumulators, then initial setup is simple, but assignment errors occur when accumulators are replaced or repositioned
Solution Approach 1:
The system automatically performs sensor-to-accumulator assignment using identification features and data transmission timing, eliminating the need for manual assignment. The measurement data collector autonomously determines which sensor corresponds to which accumulator based on unique identifiers and temporal characteristics of data transmission, ensuring reliability without manual intervention.
Solution Approach 2:
The patent replaces manual mechanical assignment processes with an automated electronic identification system. Instead of physically tracking or manually recording sensor-accumulator pairings, the system uses electronic identification features, serial numbers, and data transmission timing to automatically establish and maintain correct assignments.
2Measurement precision
If unique identification features are used for each accumulator, then sensor assignment accuracy improves, but manufacturing cost increases
Solution Approach 1:
The system uses identification features that can be copied or replicated on each accumulator, such as serial numbers or electronic identifiers. These identification copies allow the measurement data collector to distinguish between individual accumulators without requiring complex or expensive unique physical characteristics.
Solution Approach 2:
The patent utilizes可变 parameters such as data transmission time and reception time as unique identifiers for accumulators. Instead of relying solely on permanent physical identification features, the system can use temporal characteristics of data transmission that naturally vary between different accumulators in the array, providing differentiation without additional manufacturing cost.
3Reliability
If accumulators are monitored individually, then monitoring reliability improves, but system complexity increases
Solution Approach 1:
The patent combines multiple monitoring functions into a single integrated measurement data collector that handles identification, data collection, and assignment determination for all accumulators. This centralized approach maintains individual monitoring capability while reducing overall system complexity compared to distributed independent monitoring units for each accumulator.
Solution Approach 2:
The measurement data collector is designed with universal functionality to handle multiple accumulators simultaneously. It can identify, track, and monitor data from any number of accumulators using the same identification and assignment mechanisms, eliminating the need for accumulator-specific monitoring hardware and reducing system complexity.
4Measurement precision
If automated assignment determination is implemented, then assignment accuracy improves, but processing time increases
Solution Approach 1:
The system performs preliminary assignment determination during system startup or initialization phases. By establishing sensor-to-accumulator mappings before actual monitoring begins, the system avoids repeated real-time assignment calculations during operation, reducing processing time during critical monitoring periods while maintaining high assignment accuracy.
Solution Approach 2:
The patent uses rapid identification methods such as reading serial numbers or using pre-assigned identification features that can be quickly retrieved. Instead of performing complex real-time analysis to determine assignments, the system skips lengthy calculation processes by utilizing pre-stored identification data and temporal characteristics that provide immediate assignment information.

AI summary
The claimed method deals with the assignment of measuring sensors (7, 7I, 7II, 7III, 7IV) or monitoring modules of electrochemical converters, which serve, for example, to measure a voltage, a temperature, a current, a concentration and/or a resistance, or a group of these electrochemical converters, e.g., accumulators (3, 3I, 3II, 3III, 3IV), in an array of objects to be measured (3, 3I, 3II, 3III, 3IV, 12, 12I, 12II, 12III, 12IV). The method can be executed at a centralized location (1, 23, 38, 50) to establish a correspondence between an arrangement of the sensors (7, 7I, 7II, 7III, 7IV) and a spatial and/or electrical arrangement of the objects to be measured (3, 3I, 3II, 3III, 3IV, 12, 12I, 12II, 12III, 12IV). Various measurements can be performed string by string or array by array.
