Industrial Machine Data Tagging for Process Traceability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information collection systems for industrial machines lack effective methods to identify and assign process identification information to collected data, leading to challenges in traceability and management of processes executed on objects.
Innovation Solution
An information collection system that communicates with industrial machines to identify processes executed on objects and assigns process identification information to collected data, using a control device to generate system-side object IDs and process IDs, ensuring traceability even when the control device does not directly control the machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If process identification information is not assigned to collected data, then communication load is reduced, but traceability and management of processes executed on objects deteriorate
Solution Approach 1:
The system segments process information management by assigning unique process identification information to each process executed on an object. This segmentation allows individual tracking of multiple processes while maintaining overall system traceability, resolving the contradiction between reliable traceability and manageable complexity.
Solution Approach 2:
The control device preliminarily assigns process identification information to collected data before data analysis or processing occurs. This preliminary tagging enables automatic traceability without adding complexity during subsequent data handling operations.
2Reliability
If process identification information is assigned to all collected data, then traceability is improved, but communication load and data processing complexity increase
Solution Approach 1:
The system extracts only essential process identification information from the data collection process, rather than transmitting all possible data attributes. This extraction approach maintains traceability while minimizing communication load by transmitting only the necessary identification markers.
Solution Approach 2:
The control device acts as an intermediary that assigns process identification information locally without requiring constant communication with industrial machines. This intermediary role reduces communication load while maintaining centralized traceability management.
3Reliability
If the control device generates system-side object IDs and process IDs, then traceability is ensured even when machines operate independently, but device complexity increases
Solution Approach 1:
The control device performs multiple functions including data collection, process identification, and generation of system-side object IDs and process IDs. This multi-functionality consolidates traceability management in a single device, ensuring reliability while distributing complexity across integrated operations rather than requiring complex inter-device coordination.

AI summary
An information collection system for industrial machines includes processing circuitry that communicates with one or more industrial machines that execute one or more predetermined processes with respect to an object, identify, based on predetermined information received from the one or more industrial machines, the one or more predetermined processes executed with respect to the object, and assigns process identification information related to the one or more predetermined processes to collected information related to the object collected from the one or more industrial machines.
