Vessel Warning App Auto-Start via Engine Signal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vessel operators often forget to start warning applications on information terminals when operating marine vessels, leading to missed warnings about speed limits and prohibited areas, which can result in unsafe operations.
Innovation Solution
A vessel operator warning support system that includes a marine vessel with a controller and communicator that automatically transmits a start signal to the information terminal when the engine is started, ensuring the warning application is initiated, and includes features to limit engine output if the application is not started, and uses satellite positioning to determine if the vessel is on land or water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the warning application is manually started on the information terminal, then the operator can control when the application runs, but the operator may forget to start it, leading to missed warnings
Solution Approach 1:
The system performs preliminary action by automatically starting the warning application when the engine is started, eliminating the need for the operator to manually start the application. The controller detects engine start and automatically launches the warning application on the information terminal, ensuring the application is running before needed without requiring operator intervention.
Solution Approach 2:
The system implements self-service by having the vessel's own controller automatically manage the warning application startup. The controller monitors engine status and autonomously triggers the warning application without external input from the operator, making the system self-sufficient in ensuring proper operation.
2Reliability
If the warning application is automatically started when the engine is started, then the operator will not forget to start it, but the system complexity increases due to automatic detection and transmission mechanisms
Solution Approach 1:
The system uses feedback by having the controller detect engine start status and automatically transmit a start signal to the information terminal. The controller continuously monitors engine operation state and provides feedback control by launching the warning application only when the engine is actually started, ensuring reliable automatic startup without complex manual intervention systems.
3Reliability
If the engine output is limited when the warning application is not started, then the operator is forced to start the application, but the vessel operational efficiency is reduced
Solution Approach 1:
The system applies preliminary anti-action by limiting engine output before the warning application can be properly activated. When the controller detects that the warning application is not running, it preemptively restricts engine power, preventing the vessel from operating at full capacity until the warning system is activated, thereby ensuring safety protocols are followed.

AI summary
A vessel operator warning support system includes a marine vessel including an engine, a controller, and a communicator, and an information terminal configured or programmed to communicate with the communicator and to define and function as a warning application to issue a predetermined warning based on location information of the marine vessel. The controller of the marine vessel is configured or programmed to perform a control to transmit, via the communicator to the information terminal, a start signal to start the warning application when the engine is started.
