1Productivity

If non-real-time data is transmitted before real-time data without fragmentation, then communication bandwidth is utilized efficiently, but real-time data transmission is delayed and control accuracy deteriorates

Engineering Contradiction:

Improvebandwidth utilizationVSAvoidcontrol accuracy

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The non-real-time data is divided into multiple fragments with controlled sizes. The fragmentation unit calculates appropriate fragment sizes based on real-time data characteristics and transmits non-real-time fragments in sequence before real-time data arrives, ensuring that real-time data transmission is not delayed while still utilizing communication bandwidth effectively.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The fragment size of non-real-time data is dynamically adjusted based on the characteristics of real-time data. The fragmentation unit determines optimal fragment sizes in real-time to balance bandwidth utilization with the requirement of not delaying real-time data transmission, making the system adaptive to varying communication conditions.

Solution Approach 1:

The communication control device includes a fragmentation unit that divides non-real-time data into multiple fragments. This segmentation allows the system to transmit smaller data units before real-time data without requiring complex buffering or prioritization mechanisms, thus maintaining control accuracy while adding only moderate complexity through the fragmentation function.

Solution Approach 1:

The fragmentation unit dynamically determines the fragment size of non-real-time data based on the characteristics of real-time data and communication conditions. This dynamic adjustment optimizes bandwidth utilization and communication efficiency by adapting fragment sizes to current traffic patterns, while the automation of this process prevents excessive complexity increase.

Inventive Principle:

Solution Approach 1:

The fragmentation unit divides non-real-time data into multiple smaller fragments that can be transmitted sequentially before real-time data arrives. This segmentation prevents the accumulation of large non-real-time data blocks from blocking real-time data transmission, thereby maintaining control cycle accuracy while adding only the fragmentation function to the device.
