Ship Navigation via Portable Terminals and AIS Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ship navigation systems require expensive electronic equipment installed on ships, with no mention of using inexpensive and simple portable user terminals like smartphones or tablets.
Innovation Solution
A Ship Movement-Sharing Navigation Support System that utilizes a method involving a user terminal to receive position information from a management server via a mobile network and display ship icons on a nautical chart, along with tracking their movements over time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If expensive electronic equipment is installed on ships for navigation and data transmission, then navigation support and data management capabilities are improved, but system cost and device complexity increase
Solution Approach 1:
The patent uses portable user terminals (smartphones, tablets) as simple copies or representations of complex navigation systems. Instead of requiring expensive dedicated navigation equipment on each ship, the system replicates navigation support functionality through widely available portable devices that access centralized data services via mobile networks and VHF radio.
Solution Approach 2:
The patent introduces a land-based management server as an intermediary between ships and navigation support services. The server consolidates complex data processing, storage, and distribution functions, allowing simple portable user terminals on ships to access comprehensive navigation information without requiring complex onboard equipment. The management server mediates between AIS data collection and user terminal display.
2Device complexity
If portable user terminals are used instead of expensive electronic equipment, then system cost and device simplicity are improved, but data transmission reliability and navigation accuracy may deteriorate
Solution Approach 1:
The patent merges multiple communication channels (mobile telephone network and VHF radio AIS system) into a unified data transmission architecture. The land-based management server receives and integrates position information from both channels, providing redundant data paths that enhance reliability. This combination allows the system to maintain accurate navigation data even if one communication channel experiences issues.
Solution Approach 2:
The system implements feedback mechanisms where the management server continuously receives position information from multiple sources, processes the data, and provides updated navigation information to user terminals. The server can request additional data or verify information through multiple communication channels, ensuring data accuracy and reliability while using simple portable devices.
Data Source
AI summary
A Ship Movement-Sharing Navigation Support System is provided based on IoT or AI by using inexpensive and easy-to-carry user terminals such as smartphones or tablets. A method for navigating a ship comprises receiving a position information transmitted from a user terminal used in a user terminal-equipped ship via a mobile telephone network; receiving a position information via an AIS system transmitted via a VHF radio from an AIS device-equipped ship; and displaying icons of the user terminal-equipped ship and the AIS device-equipped ship on a nautical chart or radar display of the user terminal. In addition, the method comprises calculating a predicted moving route of the user terminal-equipped ship and the AIS device-equipped ship based on the information received from the user terminal and the AIS device and preventing a collision by displaying a caution or warning alert in a case there is a possibility of collision.
