Boat Network Connection Device Protocol Auto-Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection devices for networks on boats face challenges with long waiting times and erroneous protocol determination when connecting, leading to reliability issues and compatibility problems, especially when connecting to unauthenticated protocols, and require multiple communication lines, making them costly and impractical.
Innovation Solution
A connection device that identifies the network protocol autonomously by receiving a certain message with an identification field, storing this information in nonvolatile memory for future connections, and resetting the protocol information upon changes, allowing for prompt and stable communication without the need for multiple communication lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the connection device determines protocol type every time it is connected, then protocol identification can be performed, but waiting time becomes long and reliability decreases
Solution Approach 1:
The connection device performs protocol type determination in advance during the connection phase, before actual data communication begins. The determined protocol type is then stored and reused for subsequent communications, eliminating the need to redetermine the protocol type each time, thus reducing waiting time while maintaining reliable protocol identification.
Solution Approach 2:
The connection device creates a copy of the determined protocol type information and stores it in memory. This copied information is then reused for multiple communication sessions, avoiding repeated determination processes and reducing the time loss associated with redundant protocol identification.
2Adaptability or versatility
If the authentication conforming device connects to unauthenticated protocol network, then connection is possible, but authentication failure occurs and upward compatibility cannot be ensured
Solution Approach 1:
The connection device dynamically adjusts its authentication behavior based on the detected protocol type. When an unauthenticated protocol is detected, the device automatically disables authentication requirements, allowing seamless connection to both authenticated and unauthenticated networks while maintaining authentication reliability when needed.
Solution Approach 2:
The connection device changes the authentication parameter state based on the protocol type. For unauthenticated protocols, the authentication parameter is set to disabled or bypassed mode, while for authenticated protocols, normal authentication procedures are applied, ensuring compatibility across different network types without compromising security where required.
3Reliability
If multiple communication lines are provided for multiple failure diagnosis circuits, then diagnosis capability is improved, but device cost increases
Solution Approach 1:
A single communication line is designed to serve multiple failure diagnosis circuits by time-division multiplexing or protocol-based routing. The same physical communication infrastructure is used for different diagnosis functions, eliminating the need for separate dedicated communication lines for each circuit while maintaining comprehensive diagnosis capability.
Solution Approach 2:
Multiple failure diagnosis circuits are merged into a unified communication framework where a single communication line handles multiple diagnosis tasks. The system combines several diagnosis functions into one integrated communication channel, reducing the total number of communication lines required while preserving the ability to diagnose all circuits.
