Remote Operation Image Upload Control Under Line Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote information systems experience communication quality degradation due to line congestion when image data is uploaded to external servers, affecting communication delay and response degradation.
Innovation Solution
Implement designated communication control processing to suspend or reduce the transmission speed of image data when designated communication occurs, such as managing bandwidth by suspending image data transmission or lowering its priority relative to other communication tasks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image data is continuously uploaded to the external server, then the operation history information is maintained, but the communication line becomes congested and communication quality degrades
Solution Approach 1:
The system implements periodic transmission of image data to the external server instead of continuous transmission. The communication control processing suspends or reduces transmission speed during designated communication periods, and resumes normal transmission when designated communication ends. This periodic action pattern prevents line congestion while ensuring operation history information is maintained.
Solution Approach 2:
The transmission speed of image data is made dynamic rather than fixed. The communication control processing adjusts the transmission speed based on communication conditions - reducing speed during designated communication and maintaining normal speed otherwise. This dynamic adjustment resolves the contradiction between maintaining reliable operation history and preventing communication quality degradation.
2Object-affected harmful factors
If transmission speed of image data is reduced to prevent line congestion, then communication quality is maintained, but the time required to upload operation history information increases
Solution Approach 1:
The system uses periodic transmission where image data is uploaded at normal speed during non-designated communication periods and suspended or reduced during designated communication periods. This approach minimizes total upload time while maintaining communication quality, as the majority of transmission occurs at full speed when the line is available.
Solution Approach 2:
The communication control processing monitors communication conditions and dynamically adjusts transmission speed based on feedback about line congestion and designated communication status. This feedback mechanism ensures that transmission speed is optimized to prevent congestion while minimizing upload time - reducing speed only when necessary and maintaining normal speed when possible.

AI summary
An information system executes designated communication control processing of suspending transmission of image data by a designated device or reducing a transmission speed of the image data in a case where there is designated communication other than transmission of the image data acquired by the designated device between the designated device and an external server, the designated device being at least one of an operation device and an operation target operated by the operation device.
