Relay Device Dynamic Period Adjustment for Transmission Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems lack the capability to determine the entire period from when an instruction to transmit data is given to the data determination time, which limits the flexibility and efficiency of data transmission.
Innovation Solution
A relay device and communication system that alternately set first and second periods, changing the total number of these periods in each predetermined period, and determine whether communication data is stored, specifying the period to which the communication determination time belongs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the relay device uses fixed permitted and prohibited periods for priority data transmission, then the transmission control is simple, but the system cannot determine the entire period from instruction to determination time, reducing flexibility and efficiency
Solution Approach 1:
The patent applies dynamics by making the period structure adjustable rather than fixed. The relay device dynamically determines the total number of first periods and second periods in each predetermined period based on actual transmission needs. This allows the system to adapt the period configuration to match the entire transmission period from instruction to determination, improving flexibility while maintaining manageable complexity through structured dynamic adjustment.
Solution Approach 2:
The patent changes the parameter of period quantity by allowing the total number of first periods and second periods to vary. Instead of using a fixed periodic structure, the system adjusts the number of periods within each predetermined period based on the actual transmission requirements. This parameter change enables the system to cover the entire transmission period accurately while maintaining systematic control.
2Productivity
If the relay device determines transmission timing based on alternating permitted and prohibited periods, then transmission control is simplified, but data transmission efficiency is reduced due to inability to optimize timing
Solution Approach 1:
The patent applies preliminary action by determining the total number of first periods and second periods in advance for each predetermined period. This preliminary configuration allows the relay device to know the complete period structure before transmission begins, enabling accurate calculation of the entire transmission period from instruction to determination. This eliminates time loss due to uncertain period boundaries while maintaining the simplified alternating period control structure.
Solution Approach 2:
The patent uses feedback by having the relay device determine whether communication data is stored in the storage unit at the communication determination time. This feedback mechanism allows the system to verify that the determined period structure actually covers the complete transmission period from instruction to determination. The feedback ensures accuracy while maintaining efficient transmission control through the alternating permitted and prohibited period structure.

AI summary
A relay device relays communication. The relay device includes: a receiving unit that receives communication data from a communication device; a storage unit that stores the communication data received by the receiving unit; and a processing unit that performs processing. A first period and a second period are alternately set. The processing unit changes the total number of the first periods and the second periods included in a next predetermined period each time a predetermined period including the first periods and the second periods passes. The processing unit determines whether or not the communication data is stored in the storage unit. When it is determined that the communication data is stored in the storage unit, the processing unit specifies a period to which a communication determination time at which the determination has been performed belongs, from the first period and the second period.
