NC Data Collection Timing for Uninterrupted Industrial Machine Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Access to data stored or processed by numerical controllers in industrial machines is restricted during operation, making it challenging to collect the required data without disrupting the machine's operation.
Innovation Solution
A data collecting device that includes a condition determiner to check if the industrial machine is in operation and a data collector to gather data from the numerical controller only when the machine is not in operation, ensuring uninterrupted machine operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data collection is performed during industrial machine operation, then data can be collected in real-time, but access restrictions prevent complete data collection and may disrupt machine operation
Solution Approach 1:
The system determines in advance whether the industrial machine is in operation before attempting data collection. By checking the operation state beforehand and only collecting data when the machine is stopped, the system ensures complete data access without disrupting machine operation, thereby resolving the contradiction between data collection reliability and operation continuity.
2Loss of information
If data collection is performed during industrial machine operation, then real-time monitoring is achieved, but access restrictions cause incomplete data collection
Solution Approach 1:
The condition determiner checks whether the industrial machine is in operation before the data collector attempts to access data. This preliminary check ensures that data collection only occurs when the machine is stopped, guaranteeing complete data access without causing operational interruptions, thus preventing both information loss and productivity reduction.
Solution Approach 2:
The system continuously monitors the operation state of the industrial machine and uses this feedback information to control the data collection process. By adjusting data collection timing based on real-time operational feedback, the system ensures complete data acquisition while maintaining optimal machine productivity.
3Reliability
If data collection is attempted during industrial machine operation, then data acquisition is initiated, but access restrictions cause operation disruptions
Solution Approach 1:
The system performs a preliminary check of the industrial machine's operation state before initiating data collection. By determining in advance whether the machine is stopped and only proceeding with data collection under these conditions, the system ensures successful data acquisition while completely avoiding operation disruptions, thus eliminating harmful effects.
