Work Machine Operator Correlation via Identification Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control systems for work machines struggle to accurately correlate operator information with operational data, leading to ambiguous and unlinked records when personal information protection is a concern, making it difficult for owners or administrators to grasp operator performance without compromising personal data.
Innovation Solution
A control method and system that acquire and correlate identification information with operational data, generating a clear link between operators and their operational information, including metrics like operating dates, times, and fuel consumption, while ensuring personal data protection by storing and managing this information securely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If operational information is collected and totalized by a control device, then labor management and operator performance tracking are improved, but personal information protection becomes difficult to ensure
Solution Approach 1:
The system segments personal information from operational information by using identification information (anonymized data) as an intermediary. The control device totalizes operational information correlated with identification information rather than direct personal information, separating sensitive data from operational data while maintaining traceability through the identification link.
Solution Approach 2:
The patent introduces identification information as an intermediary between personal information and operational information. This mediator allows the control device to track operator performance and totalize operational data without directly handling or storing sensitive personal information, thus resolving the contradiction between management efficiency and privacy protection.
2Reliability
If operational information is provided in an ambiguous state without operator correlation, then personal information protection is maintained, but owner and administrator cannot grasp operator-performance correlation
Solution Approach 1:
The system segments the correlation relationship into two parts: the control device stores operational information correlated with identification information, while the terminal device stores the correlation between identification information and personal information. This segmentation allows operational data to be provided with operator correlation while keeping personal information protected at the terminal device.
Solution Approach 2:
The patent adds a new dimension to information flow by introducing identification information as a separate layer. Instead of directly linking personal information to operational information, the system creates a multi-dimensional correlation structure where operational information is first correlated with identification information, which then links to personal information at the terminal device.
3Loss of information
If personal information is stored outside operator control, then operational information can be correlated with operator identity, but personal information security and operator privacy are compromised
Solution Approach 1:
The patent extracts personal information from the control device and stores it exclusively at the terminal device under operator control. The control device only handles identification information (anonymized data) for correlating operational information, while personal information is taken out and kept secure at the terminal device where operators can control access.
Data Source
AI summary
A control method for a work machine, includes: acquiring a correlation between identification information for identifying operability for the work machine and operational information of the work machine, and generating a correlation between an operator who operates the work machine and the operational information by using the correlation between the identification information and the operational information and a correlation between the operator and the identification information.
