Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automation systems face challenges in ensuring timely, reliable, and complete data transmission between control devices and cloud systems due to varying data transfer rates, which can lead to incomplete or delayed data transfer, affecting the reliability and safety of automation processes.
Innovation Solution
A method that determines data transmission characteristics and selects measures to adapt data or transmission paths, using alternative paths or reducing data volume, to ensure timely, reliable, and complete data transfer between control devices and cloud systems, with components on both the control device and cloud system sides working together to implement these measures.

Engineering Contradiction Analysis
1Speed
If data is transmitted at high speed to ensure timely transfer, then transmission time is reduced, but data completeness and reliability deteriorate due to potential blockages and connection failures
Solution Approach 1:
The system performs preliminary actions by determining data transmission characteristics before actual data transmission occurs. This allows the system to assess the transmission path's capacity and reliability in advance, and take preventive measures such as selecting alternative paths or adjusting transmission parameters before blockages or connection failures occur, thereby maintaining both high speed and reliability
Solution Approach 2:
The system continuously monitors data transmission characteristics and uses this feedback to dynamically adjust transmission parameters. By analyzing transmission quality in real-time and making adjustments based on this feedback, the system can maintain optimal transmission speed while ensuring data completeness and reliability, preventing blockages and connection failures
2Quantity of substance
If large amounts of data are transmitted to ensure complete information transfer, then data completeness is improved, but transmission time increases and may cause blockages
Solution Approach 1:
The system segments large data volumes into smaller transmission units and transmits them through optimized paths. By dividing the data transmission task into manageable segments and determining the characteristics of each transmission path, the system can transmit large amounts of data efficiently without causing blockages or excessive delays, thus maintaining both data completeness and transmission speed
3Reliability
If multiple transmission paths are used to ensure reliable data transfer, then transmission reliability is improved, but system complexity increases
Solution Approach 1:
The system introduces a determination component as an intermediary that automatically assesses transmission path characteristics and makes intelligent routing decisions. This intermediary manages the complexity of multiple transmission paths by providing centralized control and automated decision-making, thereby improving transmission reliability without significantly increasing overall system complexity

AI summary
The present invention relates to a method for optimising data transmission in an automation system between a control device and at least one cloud system. The invention also relates to a corresponding control device, a corresponding cloud system, and a control system. The method comprises at least the following steps: determining (11) a data transmission characteristic at least of one transmission path which is available for data transmission by means of a first and/or a second determining component; analysing (12), on the basis of the determined data transmission characteristic, whether the data to be transmitted can be transmitted; selecting (13) at least one measure from a set of measures to adapt the data to be transmitted and/or the transmission path if the data to be transmitted cannot be transmitted, in order to allow the data transmission; and carrying out (14) the at least one selected measure.
