Dual Protocol Stack Switching for Power Network Node Migration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication networks in power supply networks require costly replacements or software updates to migrate node devices to different communication protocols, leading to reliability risks and inefficiencies in performance, throughput, and maintenance.
Innovation Solution
Node devices equipped with two protocol stacks can automatically or manually switch between communication protocols, allowing seamless migration without hardware or software changes, ensuring uninterrupted communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If node devices use a single protocol stack, then device complexity is reduced and ease of manufacture is improved, but adaptability to different communication protocols deteriorates and costly replacements are required for protocol migration
Solution Approach 1:
The node device is designed with multiple protocol stacks (first and second protocol stacks) integrated into a single device, enabling it to support multiple communication protocols simultaneously. This multi-functionality allows the device to adapt to different communication standards without requiring replacement, thereby improving adaptability while maintaining ease of manufacture through a unified hardware platform.
2Adaptability or versatility
If protocol migration is performed by replacing node devices, then adaptability to new protocols is achieved, but reliability deteriorates due to installation disruptions and costs increase
Solution Approach 1:
The node device incorporates dynamic protocol switching capability, allowing it to transition between different communication protocols during operation. The device can detect protocol compatibility issues and automatically switch from an inactive protocol stack to an active one, ensuring continuous communication without interruption. This dynamic adaptation maintains reliability during protocol migration while achieving adaptability to new protocols.
3Adaptability or versatility
If software updates are performed to change protocol stacks, then adaptability is improved, but reliability worsens due to update failures and maintenance complexity increases
Solution Approach 1:
The node device is pre-configured with both a first and second protocol stack during manufacturing, with one stack designated as active and the other as inactive. This preliminary preparation eliminates the need for complex software updates during protocol migration. The device can simply switch between pre-loaded protocol stacks, significantly reducing maintenance complexity and improving ease of repair while maintaining adaptability.

AI summary
A method is proposed for configuring a node device's current communication protocol to communicate with a hub device via a communication network implemented on a power supply network. The method is implemented by the node device, which includes electronic circuitry and stores two protocol stacks. Each protocol stack, when executed by the node device's electronic circuitry, enables the implementation of a distinct communication protocol with the hub device. The method includes: detecting (501) a predetermined event; and if the event is detected, switching (502) from one of the protocol stacks to the other, thereby changing the current communication protocol implemented by the node device. This allows migration to the use of a different communication protocol without requiring replacement of the node device or a software update.This also ensures that there is no loss of communication for the node device.
