Ring Network Nodes with Autonomous Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ring network communication systems face delays and obstruction in data transmission as the number of nodes increases, particularly in systems with multiple sensors, where continuous data transmission requires longer control periods and increased request commands.
Innovation Solution
The proposed ring network communication system introduces heteronomous and autonomous modes in nodes, allowing data transmission without a transmission request and enabling nodes to switch between modes based on operation states, reducing data transmission processes and shortening control periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple nodes transmit data continuously in a ring network, then data transmission capacity increases, but transmission delays and obstructions increase
Solution Approach 1:
The patent applies dynamics by allowing nodes to switch between heteronomous mode (transmitting only when requested) and autonomous mode (transmitting proactively when holding useful data). This dynamic mode switching enables the network to adapt transmission behavior to current conditions, allowing multiple nodes to transmit simultaneously when appropriate while avoiding conflicts, thereby increasing data transmission capacity without proportionally increasing delays
Solution Approach 2:
The patent changes the parameter of transmission control from binary (request-based or not) to multi-state (heteronomous/autonomous modes). By introducing autonomous mode as a parameter change, nodes can proactively transmit data without waiting for requests, enabling parallel transmissions and improving overall network productivity while managing delay through intelligent timing
2Adaptability or versatility
If the number of nodes increases, then network coverage and functionality improve, but data transmission obstructions and control period length increase
Solution Approach 1:
The patent applies self-service by enabling autonomous nodes to independently determine when to transmit data based on their own state (holding useful data) without requiring external requests. This self-service capability reduces the coordination overhead and control period complexity that would otherwise increase with more nodes, as each autonomous node makes independent transmission decisions rather than requiring centralized scheduling
Solution Approach 2:
The patent applies preliminary action by having autonomous nodes transmit data proactively before being requested, when they already hold useful data. This preliminary transmission approach prevents future request-response cycles, reducing the overall control period and making the network more scalable as node count increases

AI summary
Multiple nodes (2) of a ring network communication system (1) include a heteronomous node (22) and an autonomous node (23). The heteronomous node (22) operates in a heteronomous mode in which data generated by a data generation part (8) of an own node is transmitted as transmitted data Dt only when received data Dir received by a data reception part (13) includes a data transmission request. The autonomous node (23) operates in an autonomous mode in which the data generated by the data generation part (8) of the own node is transmitted as the transmitted data Dt regardless of reception of the received data Dir including the data transmission request. Data including the data transmission request is not required for the autonomous node, and the control period is shortened.
