Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication systems utilizing the Time-Sensitive Networking (TSN) standard do not effectively utilize communication resources due to the inability to complete the process of determining whether a frame is permitted to be transmitted within a certain period, especially when considering the forward gate state.
Innovation Solution
A communication control device generates transmission permission information from the gate control list, allowing for efficient use of communication resources by converting the gate control list into a format suitable for hardware processing, enabling timely completion of the transmission control process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the gate control list is used to determine whether a frame is permitted to be transmitted by checking forward gate state, then transmission control accuracy is improved, but the transmission control process cannot be completed within a certain period
Solution Approach 1:
The patent pre-calculates and stores transmission permission information for each queue based on the gate control list before actual transmission occurs. This preliminary action allows the system to bypass time-consuming forward gate state checks during real-time transmission control, completing the process within required time periods while maintaining accuracy through pre-computed results.
Solution Approach 2:
The patent prepares transmission permission information in advance as a buffer or cushion for future transmission decisions. By pre-processing the gate control list and storing the results, the system eliminates the need for real-time complex calculations, ensuring both accuracy and timely completion of transmission control processes.
2Reliability
If the gate control list processing is performed in conventional manner, then transmission control is maintained, but communication resources are not utilized effectively
Solution Approach 1:
The patent pre-generates transmission permission information from the gate control list and stores it in a lookup table or memory structure. This preliminary processing transforms the conventional sequential checking method into a direct table lookup approach, maintaining reliable transmission control while dramatically improving communication resource utilization by eliminating redundant processing overhead.
Solution Approach 2:
The patent creates a copy of the gate control list processing results in the form of transmission permission information stored in memory. Instead of repeatedly processing the original gate control list for each transmission decision, the system uses this pre-computed copy, maintaining control reliability while improving productivity by reducing processing time and resource consumption.
