Bi-directional Communication Path Switching for Remote Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems for remote control of apparatuses over long distances struggle with bi-directional communication switching based on cost considerations, leading to inefficiencies in delay and transmission capacity.
Innovation Solution
A communication system that employs a first terminal apparatus transmitting a signal via a direct communication path and receiving a second signal via a different communication path, with the first terminal apparatus adjusting its transmission based on features of the second signal, and allocating frequency resources accordingly to optimize delay and capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If direct communication is used for remote control, then transmission delay is reduced, but communication capacity is limited
Solution Approach 1:
The patent segments bi-directional communication into two independent unidirectional channels: a direct communication path for control signals (prioritizing low delay) and a relay communication path for data transmission (prioritizing capacity). This allows each path to be optimized for its specific function without compromise.
Solution Approach 2:
The patent introduces a relay station as an intermediary for the data transmission path. The relay station receives data from the first terminal apparatus and forwards it to the second terminal apparatus, enabling high-capacity communication over long distances while maintaining the direct path for immediate control responses.
2Quantity of substance
If relay communication is used for remote control, then communication capacity is improved, but transmission delay increases
Solution Approach 1:
The patent segments bi-directional communication into two independent unidirectional channels: a direct communication path for control signals (prioritizing low delay) and a relay communication path for data transmission (prioritizing capacity). This allows each path to be optimized for its specific function without compromise.
3Productivity
If communication path is switched based on cost, then resource efficiency is improved, but communication reliability deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where each terminal apparatus monitors the quality of its communication path and adjusts its behavior accordingly. The first terminal apparatus transmits control signals directly when channel conditions permit, but can switch to relay communication when direct path quality deteriorates, ensuring reliable operation.
Solution Approach 2:
The patent makes the communication path selection dynamic by allowing terminal apparatuses to switch between direct and relay communication modes based on real-time channel conditions. This dynamic adaptation ensures both resource efficiency and communication reliability by utilizing the best available path at any given moment.

AI summary
A bi-directional communication method needs to be switched on the basis of cost of bi-directional communication. Provided is a communication system including a first terminal apparatus and a second terminal apparatus, in which the first terminal apparatus includes a radio unit that transmits a first signal by using a first communication path that is a direct communication path to the second terminal apparatus, the second terminal apparatus includes a radio unit that transmits a second signal by using a second communication path that is a communication path different from the first communication path, and the first terminal apparatus transmits the first signal on the basis of a feature amount of the second signal transmitted by the second terminal apparatus.
