Industrial Machine Communication Using Segmented Periodic Regions

Solution Overview

Problem

In production systems where industrial machines periodically communicate, the non-periodic communication region is not dedicated and has a lower speed, making it impossible to guarantee the time required for transmitting data other than control data, leading to inefficient data transmission.

Innovation Solution

The introduction of a production system that utilizes periodic regions for data transmission between industrial machines, allowing for dedicated communication channels and ensuring timely data transfer by dividing data into smaller portions and transmitting them within these regions.

Core Design Contradiction:

Adaptability or versatilityVSSpeed

Solution Approach 1:

The communication region is segmented into multiple periodic regions within one period, allowing data to be divided and transmitted across multiple dedicated time slots. This segmentation enables both flexible data transmission and guaranteed time allocation for each segment.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements periodic communication regions with fixed time allocations within each period. By using periodic action instead of purely non-periodic communication, the system guarantees transmission time while maintaining the ability to handle various data types through multiple periodic regions.

Inventive Principle:

Principle #19Periodic action
