Ship Alarm Display Device with Segmented Priority Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current alarm display devices for ships struggle to effectively present large amounts of alarm information in a way that is easily understandable, leading to the potential oversight of important alerts due to lack of sufficient study in user-friendly display methods.
Innovation Solution
An alarm display device with a configuration that includes a display unit, alarm information acquiring module, memory, transmission source classification list memory, importance list memory, display target specifying module, information selecting module, and alarm information displaying module, which allows operators to specify and display alarm information by categories and importance levels, enabling a list-based, eye-friendly presentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all alarm information is displayed at once, then complete information is provided, but operator understanding becomes difficult and important alarms may be overlooked
Solution Approach 1:
The alarm information is segmented by importance level (e.g., high, medium, low priority) and transmission source category. The display target specifying module divides the comprehensive alarm data into multiple categorized groups, allowing operators to view information in manageable segments rather than overwhelming all-at-once displays.
Solution Approach 2:
The information selecting module extracts only the relevant alarm information corresponding to the specified display target from the complete alarm dataset. This extraction process filters out unnecessary information while preserving critical alerts, presenting only the subset of data that matches operator needs.
2Ease of operation
If alarm information is filtered by categories and importance levels, then operator understanding is improved, but display complexity increases
Solution Approach 1:
The alarm display device incorporates multiple functional modules (display target specifying module, information selecting module, alarm information displaying module) that work together to provide comprehensive alarm management. This multi-functional integration handles classification, filtering, and display operations within a single unified system rather than requiring separate devices.
Solution Approach 2:
The information selecting module acts as an intermediary between the complete alarm information database and the display interface. It mediates the complex filtering and selection processes, translating operator specifications into appropriate alarm subsets without exposing the underlying system complexity to the user.
3Ease of operation
If display target specification is added, then relevant information is highlighted, but operation steps increase
Solution Approach 1:
The display target specifying module provides pre-configured categories and importance levels based on common operational needs. Operators can select from these pre-established classifications without having to create custom filtering criteria, reducing the time and cognitive effort required for specification.
Solution Approach 2:
The system allows operators to specify display targets at different levels of detail depending on immediate needs. Operators can choose broad categories for overview or drill down into specific alarm types for detailed analysis, adapting the specification complexity to the local operational context rather than requiring full specification always.
Data Source
AI summary
A ship alarm display device that displays a plurality of sets of alarm information to be easily understood is provided. An alarm information acquiring module acquires the alarm information from apparatuses installed in a ship. A transmission source classification list memory stores transmission source classification lists obtained by associating each apparatus with a transmission source category. An importance list memory stores importance lists obtained by associating the alarm information with a level of importance. A display target specifying module specifies the transmission category and the level of importance as a display target. An information selecting module selects the alarm information corresponding to the specified display target from the plurality of sets of alarm information stored in memory, based on the transmission source classification lists and the importance lists. An alarm information displaying module displays only the selected alarm information in a list, on a display unit.
