Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing watercraft information collecting systems face challenges in timely updating information without excessively increasing communication traffic and data processing loads, especially when the onboard system is out of operation at preset transmission times.
Innovation Solution
A watercraft information collecting system that includes an onboard system with a communication terminal capable of collecting and transmitting information to a server, which performs an information collection process, a use termination detection process, and an information transmission process to ensure timely updates while managing communication traffic and data processing loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If periodic transmission interval is set to shorter period to timely update information, then information timeliness is improved, but communication traffic and data processing load are increased
Solution Approach 1:
The system implements periodic transmission of watercraft information at predetermined intervals. The communication terminal periodically transmits collected information to the server, balancing timely updates with reduced communication frequency compared to continuous transmission.
Solution Approach 2:
The communication terminal accumulates watercraft information locally in its storage unit before transmission. By preliminarily collecting and storing data during the period between transmissions, the terminal prepares information in advance for periodic sending, reducing the need for frequent communication.
2Loss of time
If periodic transmission interval is set to shorter period to timely update information, then information timeliness is improved, but data processing load on server is increased
Solution Approach 1:
The server receives and processes watercraft information at predetermined periodic intervals rather than continuously. This periodic processing rhythm reduces the instantaneous data processing load while maintaining timely information updates in the server's storage.
3Use of energy by moving object
If onboard system is out of operation at preset transmission time, then energy consumption is reduced, but information update timeliness deteriorates
Solution Approach 1:
The communication terminal accumulates watercraft information in its storage unit during the operational period before the system shuts down. By preliminarily collecting and storing data, the terminal ensures information is ready for transmission upon next activation, maintaining update timeliness without requiring continuous operation.
Solution Approach 2:
The system automatically transmits accumulated information when activated again, without requiring manual intervention. The communication terminal self-services by detecting its own activation state and automatically sending stored information to the server.

AI summary
A watercraft information collecting system includes an onboard system and a server outside a watercraft. The onboard system includes watercraft devices on the watercraft, and an onboard network on the watercraft connected to the watercraft devices. The onboard system includes a communication terminal communicable with the watercraft devices via the onboard network. The server is communicable with the communication terminal. The communication terminal is configured or programmed to perform an information collection process to collect information about the watercraft devices, a use termination detection process to detect a termination of the use of the onboard system, and an information transmission process to transmit the information collected by the information collection process to the server. The server is configured or programmed to register the information transmitted from the communication terminal in a storage.
