Ethernet Frame Control for Multiple Serially Connected Nodes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Ethernet communication systems require multiple one-to-one communications with each node device, leading to increased communication time and complexity when controlling multiple target devices.
Innovation Solution
An electronic apparatus generates an Ethernet frame with a data field containing multiple node areas and a control command, allowing simultaneous communication with multiple node devices, and includes a custom field for control code information and feedback frames to ensure integrity of command execution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If one-to-one communication is performed with each node device, then control commands can be transmitted to multiple target devices, but communication time increases and the control process becomes complicated
Solution Approach 1:
The patent merges multiple one-to-one communication operations into a single Ethernet frame that can simultaneously address multiple target node devices. The Ethernet frame includes a destination address field that can contain multiple node addresses, allowing the primary device to transmit control commands to multiple secondary devices in one communication action rather than requiring separate transmissions for each device.
Solution Approach 2:
The Ethernet frame structure is designed with multi-functionality to handle both single-target and multi-target communications. The destination address field can be configured to include one or multiple node addresses depending on the communication needs, making the same communication mechanism universally applicable to different scenarios without requiring separate specialized protocols.
2Productivity
If multiple Ethernet frames are transmitted to control each target node device separately, then precise control is achieved, but the number of communications increases and data transmission takes longer
Solution Approach 1:
Multiple separate Ethernet frames targeting individual node devices are merged into a single Ethernet frame that can carry control commands for multiple target devices simultaneously. This consolidation reduces the total number of communication transactions from n separate frames to one frame, directly improving data transmission efficiency and reducing the quantity of communication operations required.
