Communication Device Time-Slot Scheduling for Periodic Slave Sub-Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication devices face difficulties in enabling slaves to periodically transmit, receive, or transmit and receive sub-data due to the lack of efficient scheduling for secondary communication bands.
Innovation Solution
A communication device with a processing part that executes communication and setting processing, allowing for the transmission of main frames in a first period and allocating a shorter second period with time slots to slaves for sub-data transmission and reception in a second period.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a communication device uses a first communication band for main data transmission in a first period, then main data can be transmitted reliably, but it becomes difficult for slaves to periodically transmit, receive, or transmit and receive sub-data
Solution Approach 1:
The communication band is segmented into a first communication band for main data transmission and a second communication band for sub-data transmission. This segmentation allows slaves to periodically communicate sub-data in the second band without interfering with the main data transmission in the first band, thus resolving the contradiction between reliable main data transmission and slave periodic sub-data communication capability
Solution Approach 2:
The patent introduces a time dimension by defining a first period for main data transmission and a second period (shorter than the first) for sub-data transmission. This temporal dimensionality change enables slaves to periodically transmit, receive, or exchange sub-data in the second communication band during specific time slots, while maintaining reliable main data transmission in the first band during the first period
2Adaptability or versatility
If a communication device allocates a second communication band for sub-data transmission, then sub-data can be transmitted, but the device complexity increases due to need for dual band management
Solution Approach 1:
The communication device is designed with multi-functionality to handle both first and second communication bands. The device can transmit main data in the first band and sub-data in the second band using the same hardware resources, thus providing sub-data transmission capability without proportionally increasing device complexity
Solution Approach 2:
The patent implements periodic action by transmitting main data in the first period and sub-data in the second period (which is shorter than the first period). This periodic structure simplifies band management by creating predictable transmission patterns, reducing the complexity of dual band management while maintaining versatile sub-data transmission capability

AI summary
A communication device includes a processing part and a communication part that communicates with one or more slaves. The processing part has a function of executing communication processing and setting processing. The communication processing is processing for transmitting a main frame including main data from the communication part to one or more slaves in a first period. The setting processing is processing for setting a second period shorter than the first period and a time slot allocated to at least one slave among the one or more slaves in every second period.
