Industrial Machine Data Matching Using Changed Region Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current control systems for industrial machines, such as CNCs and PCs, face inefficiencies in matching and updating data, leading to prolonged processing times, reduced operability, and increased operator burden due to the difficulty in identifying and transferring only changed data regions.
Innovation Solution
A control system that utilizes a changed data identification list with type and subdivision data storage units, along with identifiers like flags or counters, to automatically distinguish and transfer only the changed data regions, thereby reducing processing time and enhancing operability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all types of data are transferred to equalize contents between devices, then data completeness is improved, but processing time increases to minutes and productivity declines
Solution Approach 1:
The patent segments the data transfer process by introducing a changed data identification list that divides data into categories (options, parameters, NC programs, macro programs, macro variables, work origin offsets, tool offsets, tool shape data, tool management data) and further into regions. This segmentation allows the system to identify and transfer only the specific changed regions rather than all data, resolving the contradiction between data completeness and processing speed.
Solution Approach 2:
The patent extracts only the changed data portions from the complete data set by using identification lists that track which regions have been modified. The extraction process pulls out specifically the changed regions (e.g., only modified parameters or specific macro programs) and transfers them, eliminating the need to transfer entire data sets and thus improving productivity while maintaining data completeness.
2Productivity
If operator selects and transfers only changed data types, then processing time is reduced, but operator burden increases due to need to remember or visually check changed data
Solution Approach 1:
The patent implements self-service by automatically generating and maintaining the changed data identification list without operator intervention. The system automatically tracks which data regions have changed and presents this information to the operator, eliminating the burden of manual tracking and selection while still enabling selective transfer of only changed data portions.
Solution Approach 2:
The patent introduces feedback mechanisms where the system provides information about which data has changed back to the operator through the identification list. This feedback loop allows the operator to see exactly what has changed without having to remember or manually check, reducing operator burden while maintaining the efficiency of selective data transfer.
3Productivity
If only changed data types are selected for transfer, then some processing time is reduced, but several tens of seconds are still required per type resulting in increased overall processing time
Solution Approach 1:
The patent further segments data within each type into multiple regions (e.g., dividing parameters into different functional groups or time periods). This fine-grained segmentation allows the system to identify and transfer only the specific changed regions within each data type, reducing the transfer time from several tens of seconds per type to a much shorter duration by targeting only the minimal necessary data portions.
Solution Approach 2:
The patent extracts only the specific changed regions within each data type using the detailed identification list. Rather than transferring entire data types that take several tens of seconds, the system extracts and transfers only the specific changed portions (e.g., only the modified parameters in a specific region), dramatically reducing the total transfer time while maintaining data completeness.
