Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cloud-type control systems, the execution timings of data processing among multiple terminals can differ, leading to desynchronization, which is challenging to address effectively with existing technologies.
Innovation Solution
An information processing device that acquires data processing periods from target terminals, determines a shared data transmission period, and controls the execution timings of data processing to synchronize the operations across terminals.

1Ease of operation
If terminals operate independently in a cloud-type control system, then each terminal can execute data processing autonomously, but execution timings of data processing become desynchronized among terminals
Solution Approach 1:
The master station acquires information on data processing periods from each terminal and uses this feedback to determine a unified data transmission period. The control unit then controls execution timings based on this determined period, creating a closed-loop synchronization mechanism that maintains both autonomous operation and temporal coordination among terminals
Solution Approach 2:
The invention establishes a universal data transmission period that applies to all terminals in the system. This common timing framework allows different terminals to maintain their own data processing autonomy while simultaneously adhering to a shared synchronization standard, enabling multi-functional operation with coordinated timing
2Reliability
If a unified data transmission period is established for all terminals, then execution timings are synchronized, but the system requires complex coordination between master station and terminals
Solution Approach 1:
The system divides synchronization responsibilities by designating a master station that centralizes the determination of the data transmission period. Individual terminals only need to receive control instructions and adjust their execution timings accordingly, rather than each terminal independently calculating synchronization parameters. This segmentation reduces the coordination complexity at the terminal level while maintaining overall system synchronization
