Shovel Sound Data Association for Maintenance Diagnostics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shovel technologies do not effectively record or associate sound data during operation, making it difficult to share information between operators and maintenance personnel, which hinders diagnostic and maintenance processes.
Innovation Solution
Incorporating a data acquisition device that collects operation information and sound data from state detecting sensors, and a management system that stores and displays this information, allowing for the sharing of sound data during shovel operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If sound data is recorded during shovel operation, then information sharing between operator and service person is improved, but device complexity increases
Solution Approach 1:
The patent combines sound data recording with existing operation information storage in a single integrated system. The storage unit stores both operation information from sensors and sound data from the sound collector, associating them through timing information. This merging approach enables information sharing between operator and service person while avoiding the need for separate complex systems.
Solution Approach 2:
The controller acts as an intermediary that collects operation information from various sensors, manages timing information, and coordinates storage in the storage unit. It also handles transmission of combined operation and sound data to external devices, simplifying the overall system architecture by centralizing data management functions.
2Reliability
If operation information and sound data are stored in association, then diagnostic capability is improved, but data storage requirements increase
Solution Approach 1:
The patent segments data storage by organizing operation information and sound data as separate but associated datasets. Each dataset is structured with timing information that enables correlation without requiring redundant storage. The controller processes and structures data in manageable segments that can be efficiently stored and retrieved for diagnostic purposes.
3Ease of repair
If sound data is transmitted to management device, then remote maintenance support is improved, but communication data transmission load increases
Solution Approach 1:
The shovel system preliminarily processes and structures sound data and operation information before transmission, organizing them with timing associations and identifying key diagnostic information. This preliminary action reduces the need for extensive data transmission and enables more efficient remote analysis by the management device, thereby reducing communication energy consumption.
Data Source
AI summary
A shovel includes a data acquisition device and a storage. The data acquisition device acquires operation information indicating a status of each part of the shovel during operation of the shovel and sound data during operation of the shovel, from a state detecting sensor, and wherein the storage stores the operation information in association with the sound data.
