Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measurement or protective devices in electrical protective technology require intermediate 'merging units' and switches for connecting to measurement transducers, leading to complex and costly system implementations.
Innovation Solution
A measurement or protective device with a communication unit that directly connects to both measurement transducers and a superordinate data bus, processing phase-conductor-related samples to form sampling-time-related messages, thereby eliminating the need for separate merging units and switches, and utilizing 3-port network connections for full-duplex operation and data reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If intermediate merging units and switches are used to connect measurement transducers, then connection reliability is improved, but device complexity and system cost increase
Solution Approach 1:
The patent integrates the functions of merging units and switches directly into the measurement or protective device. The communication unit combines data from multiple measurement transducers and interfaces with the data bus internally, eliminating the need for separate merging units and switches while maintaining connection reliability and reducing system complexity.
2Productivity
If intermediate merging units and switches are used, then data processing capability is improved, but manufacturing cost increases
Solution Approach 1:
The communication unit within the measurement or protective device performs data processing functions that previously required separate merging units. By integrating these capabilities, the system maintains data processing capability while reducing the number of components that need to be manufactured and assembled, thereby lowering manufacturing costs.
Solution Approach 2:
The measurement or protective device is designed with universal interfaces and a communication unit that can handle multiple data sources and formats. This multi-functionality allows the device to process data from various measurement transducers directly, eliminating the need for specialized merging units for different device types and reducing overall system cost.
3Device complexity
If direct connection to measurement transducers is implemented, then device complexity is reduced, but connection reliability may worsen
Solution Approach 1:
The communication unit acts as an intermediary between the measurement transducers and the data bus. It receives data directly from measurement transducers through interfaces, processes and formats the data internally, then transmits it to the data bus. This internal mediation maintains connection reliability while keeping the overall system simple by eliminating external merging units and switches.

AI summary
A measurement or protective device has an interface for establishing a connection to at least one measurement transducer and a further interface for connecting to a superordinate data bus. In order to allow the measurement or protective device to be used in a particularly universal manner and to make it possible for complex protective systems to be constructed in a particularly cost-effective manner, a communication unit is provided in the measurement or protective device. The communication unit is connected to both interfaces, can be directly connected to the measurement transducer via the interface, can be connected to the superordinate data bus via the further interface, forms messages and transmits them to the superordinate data bus.
