Energy operations across domains
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Energy operations across domains face challenges due to differences in communication protocols between devices, such as Common Industrial Protocol (CIP) and non-CIP protocols, which hinder seamless data exchange and management.
Innovation Solution
A method is introduced that creates a native node with a proxy data structure using a native protocol and a foreign node with a foreign data structure, linked by a translation function that converts information between them, enabling communication across domains through a Common Industrial Protocol (CIP) and non-CIP protocols using a communication stack and message middleware for publish/subscribe instances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If devices use different communication protocols (CIP and non-CIP), then device functionality and protocol-specific optimization are improved, but data exchange and management between devices are hindered
Solution Approach 1:
The patent introduces a gateway device as an intermediary between CIP and non-CIP protocol domains. The gateway includes a CIP protocol processing module and a non-CIP protocol processing module that work together to translate and forward messages between different protocol domains, enabling seamless data exchange while maintaining protocol-specific optimizations.
Solution Approach 2:
The gateway device is designed with multi-functional capabilities to handle both CIP and non-CIP protocols simultaneously. It can process energy management messages in both protocol formats, act as both client and server depending on the communication direction, and provide universal energy management functions across heterogeneous device domains.
2Ease of operation
If protocol translation is implemented between CIP and non-CIP devices, then seamless data exchange is enabled, but system complexity increases
Solution Approach 1:
The gateway device segments the protocol translation function into distinct modules: a CIP protocol processing module for handling CIP messages and a non-CIP protocol processing module for handling non-CIP messages. This segmentation isolates protocol-specific complexity within dedicated modules while maintaining a unified energy management interface.
Solution Approach 2:
The gateway acts as an intermediary that abstracts the translation complexity from end devices. By centralizing the protocol conversion logic in the gateway, individual devices can remain simple while still achieving seamless communication through the gateway's intelligent message routing and translation capabilities.
3Adaptability or versatility
If energy management operations are performed across protocol domains, then comprehensive power management is achieved, but communication overhead increases
Solution Approach 1:
The patent merges multiple protocol-specific communication operations into unified energy management operations at the gateway level. By consolidating message routing, translation, and forwarding functions in the gateway, the system reduces redundant communication overhead while achieving comprehensive cross-domain power management.
Solution Approach 2:
The gateway implements feedback mechanisms where message routing and translation decisions are optimized based on communication patterns and energy management requirements. The system learns from communication overhead and adjusts its message handling strategies to minimize energy consumption while maintaining effective cross-domain management.
Data Source
AI summary
For energy operations across domains, a method generates a native node and a foreign node that includes a foreign data structure that is defined with a foreign protocol and that represents information of a foreign device in a foreign namespace. The method links the native node and the foreign node in a native namespace and the foreign namespace by a translation function that automatically converts information between the foreign data structure and the proxy data structure using protocol specific structure converting functions. The method further establishes a first publish/subscription instance with message middleware for the foreign device as publisher of the first publish/subscription instance. The method translates a message from the foreign device using the communication stack.
