Industrial Machine Data Buffering for Low-Polling Production Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing production systems face increased processing loads due to the need for regular polling between industrial machines and external devices to collect and transmit operation data, leading to inefficiencies and potential control accuracy issues.
Innovation Solution
A production system is introduced that segregates data storage into synchronous and asynchronous areas within the industrial machine, allowing data to be written into the asynchronous area and transmitted externally, thereby eliminating the need for continuous polling and reducing processing loads by utilizing a separate control circuit for data transmission.

Engineering Contradiction Analysis
1Reliability
If regular polling is used to collect and transmit operation data between industrial machines and external devices, then data can be collected and transmitted, but the processing load on both the industrial machine and external devices increases
Solution Approach 1:
The storage area in the industrial machine is divided into a synchronous area and an asynchronous area. The synchronous area is regularly synchronized with external devices, while the asynchronous area allows data to be written without immediate synchronization. This segmentation enables data to be stored in the asynchronous area and only synchronized when necessary, reducing the frequency of polling operations and lowering the processing load on both the industrial machine and external devices.
2Loss of information
If regular polling is performed to collect operation data, then data can be transmitted to external devices, but control accuracy may be compromised due to increased processing loads
Solution Approach 1:
Data is pre-written into the asynchronous area of the industrial machine before synchronization occurs. This preliminary action ensures that data is captured and stored locally without requiring immediate communication with external devices. The synchronous area is then updated from this pre-captured data, ensuring complete data transmission while reducing the frequency of polling operations, thereby maintaining control accuracy.
