Shipboard Navigation Simulation Module for Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems for ships are inadequate in providing timely and reliable decision-making support to operators to avoid collisions, especially in complex conditions such as narrow channels, poor visibility, or near coastlines, due to limitations in data collection and processing speed, and presentation of information.
Innovation Solution
A navigation support system that integrates multiple sources of information, including sensors and cameras, with a navigation simulation module to determine simulated anti-collision routes and suggest evasive maneuvers, utilizing a communication architecture like MQTT for real-time data exchange between shipboard and ground-based operators, ensuring effective and reliable decision-making support.

Engineering Contradiction Analysis
1Speed
If traditional navigation systems collect and process information using conventional hardware and software, then the system structure is relatively simple, but the processing speed is insufficient and the decision-making support is not timely
Solution Approach 1:
The system divides navigation information processing into multiple independent modules: data collection module, data processing module, simulation module, and display module. Each module handles specific tasks independently, enabling parallel processing and improving overall processing speed without requiring a complete system overhaul.
Solution Approach 2:
The system introduces a virtual dimension by creating simulated navigation scenarios that parallel the real-world situation. This allows the system to process and analyze multiple potential outcomes simultaneously, significantly accelerating decision-making support while maintaining manageable system complexity through software-based simulation.
2Reliability
If the system integrates multiple information sources including sensors and cameras, then the reliability of navigation support is improved, but the device complexity increases
Solution Approach 1:
The system merges data from diverse sources (sensors, cameras, navigation systems) into a unified simulation environment. By integrating these sources through a common processing framework rather than handling them separately, the system achieves high reliability in decision-making support while controlling complexity through standardized data integration protocols.
Solution Approach 2:
The simulation module acts as an intermediary layer between raw data from multiple sensors and the operator. This intermediary processes, validates, and synthesizes information from various sources, ensuring reliable decision-making support while shielding the operator from the underlying system complexity through a simplified interface.
3Area of stationary object
If the system processes information remotely through satellite connection, then the coverage area is expanded, but the time required for information collection and processing increases
Solution Approach 1:
The system performs preliminary processing of navigation data locally before satellite transmission is required. By pre-processing and filtering information on-board, the system reduces the amount of data needing remote transmission and can provide immediate decision support without waiting for satellite confirmation, thus expanding coverage while minimizing time loss.
Solution Approach 2:
The system maintains continuous local processing and simulation capabilities that operate independently of satellite connection status. This ensures uninterrupted navigation support and decision-making capability, allowing the system to expand coverage area through satellite when available while maintaining timely response through continuous local operation.
