Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine tool monitoring systems face issues with unpredictable response order from the machine tool to parameter acquisition requests from multiple monitoring devices, leading to incomplete or skipped parameter acquisitions, which affects accurate data collection.
Innovation Solution
A machine tool data acquisition device comprising a monitoring device connection module, a command establishing module, and a machine tool connection module that processes far-end acquisition commands to establish sequenced near-end acquisition commands, ensuring all parameter acquisition requests are transmitted and received in a predictable and complete manner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple monitoring devices transmit parameter acquisition requests to the machine tool simultaneously, then the data collection coverage is improved, but the response order becomes unpredictable and parameters may be skipped
Solution Approach 1:
The patent introduces an intermediary device (the machine tool data acquisition device) that receives far-end acquisition commands from multiple monitoring devices, converts them into near-end acquisition commands with defined sequences, and transmits them to the machine tool. This intermediary resolves the conflict by providing a coordination layer that ensures complete parameter acquisition while maintaining multi-device data collection coverage.
Solution Approach 2:
The patent applies preliminary action by pre-establishing a sequence for near-end acquisition commands before transmission to the machine tool. The command establishing module assigns a specific order to parameter acquisition requests in advance, ensuring that all parameters are acquired completely without skipping, while maintaining the benefits of multiple monitoring devices transmitting simultaneously.
2Device complexity
If the machine tool responds to parameter acquisition requests one at a time, then the processing load is reduced, but some requests may be accidentally skipped
Solution Approach 1:
The patent implements feedback mechanisms where the machine tool data acquisition device monitors the responses from the machine tool and tracks which parameters have been successfully acquired. This feedback loop ensures that if any parameter requests are skipped or not responded to, the system can detect and handle the situation, maintaining complete data acquisition while keeping the machine tool's processing load manageable through sequential handling.
3Productivity
If far-end acquisition commands are transmitted from multiple monitoring devices at the same time, then the monitoring efficiency is improved, but the parameter acquisition may be incomplete
Solution Approach 1:
The patent applies segmentation by dividing the parameter acquisition process into distinct phases: receiving far-end commands from multiple monitoring devices, converting them into sequenced near-end commands, and transmitting them systematically to the machine tool. This segmentation allows multiple monitoring devices to operate simultaneously (maintaining high monitoring efficiency) while ensuring that parameter requests are processed in an organized sequence that prevents data loss.
