Fishing Site Recommendation Using Watercraft Function Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fishing site information systems require users to perform manual input of fishing data, leading to incomplete data and inaccurate determination of fishing activities, and struggle to differentiate between fishing and non-fishing activities based on positional information.
Innovation Solution
A system comprising a watercraft with a position detector, marine propulsion devices, and a controller that automatically determines fishing activities and transmits data to a server, which estimates and recommends fishing sites without requiring user input, using fishing-related operating functions and execution information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual input of fishing data is required, then data completeness can be improved, but user burden and time consumption increase
Solution Approach 1:
The system automatically collects fishing data through sensors and onboard equipment without requiring user input. The controller gathers information from position detectors, marine propulsion devices, and other onboard systems to automatically determine fishing activities and compile data, eliminating the need for manual entry while maintaining data completeness
Solution Approach 2:
Manual data entry is replaced with automated electronic data collection through sensors, communication devices, and controller systems. The mechanical action of user input is substituted with automated electronic sensing and data transmission processes
2Device complexity
If only positional information is used to determine fishing activities, then system complexity is reduced, but determination accuracy deteriorates
Solution Approach 1:
The system merges multiple data sources including position information, marine propulsion device operating states, watercraft operating functions, and environmental sensors to comprehensively determine fishing activities. This combination of multiple information sources improves determination accuracy without excessive complexity increase
Solution Approach 2:
The controller serves multiple functions: it controls marine propulsion devices, collects data from various sensors, determines fishing activities, and transmits information to the server. This multi-functionality allows the system to achieve accurate fishing determination using existing onboard systems
Data Source
AI summary
A fishing site information providing system includes an input operable by an operator to select a fishing-related watercraft operating function of a marine propulsion device on a watercraft. A watercraft operating controller is connected to the input and controls the marine propulsion device to execute the fishing-related watercraft operating function selected by the operator. A Data Communication Module (DCM) transmits to a cloud server the fishing-related watercraft operating function executed by the marine propulsion device and execution information including a site of execution of the fishing-related watercraft operating function. The cloud server estimates a recommended fishing site or sea route based on the fishing-related watercraft operating function and the execution information and transmits the estimated recommended fishing site or sea route to the DCM. The watercraft operating controller controls a Multi-Function Display (MFD) to display the recommended fishing site or sea route estimated by the cloud server.
