Master Device Token Transfer for Ring Network Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ring networks face issues with reliable data transmission control, leading to potential communication failures due to improper transmission or absence of data transmission control between communication devices, especially when the communication line is faulty.
Innovation Solution
A master device and communication system with a transceiver and controller configuration that enables reliable transmission and reception of data control by sending transfer commands, receiving responses, and managing the execution of data control through confirmation notifications, preventing conflicts and ensuring proper communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data transmission control is transmitted using specific data packets on a communication line, then communication control can be achieved between devices, but reliability deteriorates when the communication line is faulty causing multiple or zero data transmission controls
Solution Approach 1:
The patent introduces a dedicated token transmission line separate from the data communication line. This intermediary channel ensures that token transmission is not affected by data line faults, resolving the reliability issue where faulty communication lines caused multiple or zero data transmission controls. The token line acts as a mediator that protects the control mechanism from disturbances in the data transmission path.
Solution Approach 2:
The patent divides the communication system into two separate channels: a data communication line for transmitting data packets and a dedicated token transmission line for transmitting data transmission controls. This segmentation isolates the control mechanism from data transmission issues, preventing faults in one channel from affecting the other, thereby improving reliability without excessive complexity.
2Device complexity
If a single master node issues tokens to slave nodes in a loop network, then communication control is simplified, but reliability worsens when communication line failures cause loss of data transmission control
Solution Approach 1:
The patent employs a dedicated token transmission line as an intermediary that protects against communication line failures. This separate channel ensures that even when the data communication line fails, the token can still be transmitted reliably from the master node to slave nodes, maintaining control availability without complicating the overall network structure.
Solution Approach 2:
The patent prepares for potential communication line failures by establishing a dedicated token transmission line in advance. This prior cushioning measure ensures that when faults occur in the data communication line, the token transmission is already protected and can continue without interruption, maintaining reliability without adding complex reactive measures.
Data Source
AI summary
The communication method comprises transmitting a transfer command to transfer the data control, which enables execution of controlling data stored in one or more communication devices connected to at least one of the first and second master devices, from the first master device to the second master device through a first communication line, transmitting a response to the transfer command from the second master device to the first master device through the first communication line, and transmitting a confirmation notification for the response from the first master device to the second master device through the first communication line. The execution of controlling data in the first master device is stopped when the first master device has transmitted the confirmation notification, and the execution of controlling data in the second master device is enabled when the second master device has received the confirmation notification.
