Industrial Machine Data Snapshot Transfer Under High Communication Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems where industrial machines need to acquire state data for breakdown prediction and diagnosis, high communication loads can lead to increased data transmission demands, causing further load increases and potential data loss or inaccuracy when acquiring data at desired timings.
Innovation Solution
A communication system where a first industrial machine sends a copy instruction to a second industrial machine, allowing it to copy state data from an original storage area to a secondary storage area independently, reducing immediate data transmission during high loads and enabling data acquisition at desired times without immediate updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If state data is transmitted immediately upon request during high communication loads, then data acquisition speed is improved, but data accuracy deteriorates due to updates occurring during transmission
Solution Approach 1:
The patent applies preliminary action by copying state data from the first storage area to a second storage area before transmission occurs. This advance preparation ensures that the data to be transmitted is already captured and isolated, preventing any updates that might occur during the transmission process from affecting data accuracy. The copy is made in advance of the actual data transfer, ensuring consistency.
Solution Approach 2:
The patent uses the copying principle by creating a duplicate of the state data in a second storage area. Instead of transmitting data directly from the original storage area where it continues to be updated, a copy is made and this copy is what gets transmitted. This eliminates the risk of data changes during transmission while maintaining fast data acquisition.
2Loss of energy
If data transmission is delayed to reduce communication load, then communication load is reduced, but data timeliness deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-copying the state data to the second storage area before transmission is needed. This preparation step allows the actual transmission to occur efficiently without requiring real-time data processing during high-load periods. The copy is ready in advance, enabling timely transmission when communication conditions improve.
Solution Approach 2:
The second storage area acts as an intermediary buffer between the original data source and the transmission process. It holds a snapshot of the state data that can be transmitted independently from the ongoing data updates in the first storage area. This intermediary structure decouples the transmission timing from the data generation timing, allowing load management without sacrificing timeliness.
3Reliability
If continuous data transmission is performed to ensure data availability, then data availability is improved, but communication load increases
Solution Approach 1:
The patent uses copying to create a standalone copy of state data in the second storage area that can be transmitted without requiring continuous access to the original data source. This copy mechanism ensures data availability for transmission while reducing the communication load by eliminating the need for continuous real-time data retrieval and transmission from the primary storage area.
Solution Approach 2:
The second storage area serves as an intermediary that stores data copies for transmission purposes. This intermediary structure allows the system to provide data availability guarantees by having pre-prepared data ready for transmission, while simultaneously reducing communication load by not requiring continuous real-time data access from the primary storage area during transmission operations.

AI summary
A communication system comprising a first industrial machine and a second industrial machine, which are configured to communicate with each other, wherein the first industrial machine is configured to transmit a copy instruction to the second industrial machine, and wherein the second industrial machine is configured to: update data in a first storage area based on its own operation; copy the data in the first storage area to a second storage area when the copy instruction is received; and transmit the data in the second storage area to the first industrial machine.
