Time-Synchronized Network Control for Split Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional control systems for manufacturing devices or production facilities face challenges in efficiently transmitting control system data and information system data on the same network, leading to increased processing loads and reduced precision in predictive management due to limited data handling capacity.
Innovation Solution
The solution involves assigning separate communication bands to time-synchronized control devices for control system data and information system data, allowing for simultaneous transmission without increasing processing loads, thereby enabling high-speed and high-precision control and data collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the control device transmits both control system data and information system data on the same network, then the processing load is concentrated on the control device, but the data handling capacity is exceeded and predictive management precision is reduced
Solution Approach 1:
The patent divides the control devices into two types: first control devices that transmit only control system data, and second control devices that transmit only information system data. This segmentation distributes the data transmission responsibilities across multiple devices, preventing any single control device from being overloaded and ensuring that both control precision and predictive management quality are maintained.
2Quantity of substance
If the control device handles large amounts of information system data, then the processing load increases, but the control speed and precision are reduced
Solution Approach 1:
The patent segments the data transmission functions by designating second control devices specifically for transmitting information system data to the host device. This separates the control functions (handled by first control devices) from the data collection functions (handled by second control devices), allowing control operations to maintain high speed and precision while information system data is collected and transmitted without interfering with control performance.
3Ease of operation
If separate networks are used for control system data and information system data, then processing load is distributed, but system complexity increases
Solution Approach 1:
The patent segments the roles of control devices rather than creating separate physical networks. First control devices are assigned to transmit control system data, while second control devices are assigned to transmit information system data. Both types of devices operate on the same network infrastructure, but their functional segmentation achieves load distribution without requiring complex network architecture.

AI summary
A first control device connected to a network in which data is updated at every predetermined cycle transmits, at every predetermined cycle, first data used for controlling a manufacturing device or a production facility, using a first communication band among communication bands possessed by the network. A second control device connected to the network and time-synchronized with the first control device transmits second data used for setting and managing the manufacturing device or the production facility, using a second communication band other than the first communication band among the communication bands possessed by the network.
