Vessel Diagnostic Filtering for Real-Time Remote Failure Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current remote monitoring systems for vessels face challenges in accurately diagnosing equipment failures due to incomplete information and high volumes of irrelevant data, leading to delayed or incorrect troubleshooting, and require costly infrastructure for effective communication between vessels and diagnostic centers.
Innovation Solution
A diagnostic apparatus on the vessel processes messages from nautical electronic devices using National Marine Electronics Association (NMEA) 0183 messages, filters relevant data, and transmits failure information directly to a remote diagnostic center via satellite communication, enabling efficient troubleshooting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If satellite communication links are used to transmit all device data to remote diagnostic centers, then real-time monitoring capability is improved, but data transmission volume and processing costs increase significantly
Solution Approach 1:
The patent extracts and transmits only failure-relevant data (alarm states, error codes, diagnostic information) from the complete device data set, filtering out normal operational parameters. This selective extraction reduces satellite communication bandwidth requirements while maintaining the ability to detect and diagnose equipment failures in real-time.
Solution Approach 2:
The diagnostic apparatus on the vessel performs local data processing and filtering, analyzing device data on-board to identify only those parameters indicating potential failures. This local quality enhancement ensures that only diagnostically valuable information is transmitted remotely, optimizing the balance between real-time monitoring and communication costs.
2Measurement precision
If complete device data is transmitted to remote diagnostic centers, then diagnosis accuracy is improved, but processing time and infrastructure costs increase
Solution Approach 1:
The diagnostic apparatus performs preliminary data processing, filtering, and preliminary diagnosis on the vessel before transmitting information to the remote center. This preliminary action pre-preprocesses the data, so that when data is received at the remote diagnostic center, further processing is minimized, thereby reducing total diagnosis time while maintaining accuracy.
Solution Approach 2:
The system extracts only the most diagnostically critical parameters and failure indicators from the complete device data set, removing redundant normal operational data. This extraction maintains diagnosis accuracy by focusing on failure-relevant information while significantly reducing the volume of data requiring remote processing time.
3Ease of manufacture
If crew members manually report device failures, then communication infrastructure costs are reduced, but information completeness and timeliness deteriorate
Solution Approach 1:
The diagnostic system implements self-service automated monitoring where the diagnostic apparatus continuously monitors device parameters, automatically detects failures, and generates diagnostic reports without requiring crew intervention. This self-service approach maintains information completeness and timeliness while eliminating the need for expensive dedicated communication infrastructure for manual reporting.
Solution Approach 2:
The system establishes automated feedback loops where device data is continuously collected, analyzed, and used to trigger automatic failure notifications. This feedback mechanism ensures that failure information is captured completely and transmitted timely without relying on crew members to manually observe and report issues, thereby maintaining information quality while reducing infrastructure requirements.
