Route Control Signals With Extended Validity for Moving Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless control systems for terminal apparatuses, such as robots and vehicles, face inefficiencies when control signals are not received within predetermined timing, leading to disruptions in operation and reduced performance.
Innovation Solution
A system that generates and transmits control signals with extended validity periods and employs retransmission strategies, including changing resource blocks, network slices, modulation schemes, and antenna patterns, to ensure continuous operation of terminal apparatuses even if initial signals are not received promptly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If control signals are transmitted with predetermined timing, then the terminal apparatus can operate efficiently, but the system reliability deteriorates when signals are not received
Solution Approach 1:
The system generates route information in advance for the terminal apparatus to execute. This preliminary action ensures that even if control signals are not received at predetermined timing, the terminal apparatus can continue operating based on pre-generated route information, thus maintaining both operation efficiency and continuity
Solution Approach 2:
Route information acts as an intermediary between the control system and the terminal apparatus. Instead of relying solely on real-time control signals, the terminal apparatus receives route information that mediates the control process, allowing it to autonomously execute movements even when control signals are delayed or lost
2Reliability
If control signals are transmitted repeatedly at predetermined timing, then the terminal apparatus can maintain operation, but the system complexity increases
Solution Approach 1:
Route information is generated in advance containing complete movement instructions. This eliminates the need for repeated control signal transmissions at predetermined timing, as the terminal apparatus can execute the pre-generated route information autonomously, thereby reducing control system complexity while maintaining reliability
Solution Approach 2:
The terminal apparatus is enabled to autonomously execute route information without requiring continuous control signals. This self-service capability reduces the complexity of the control system by eliminating the need for complex signal transmission and reception protocols while ensuring reliable operation
3Reliability
If the validity period of control signals is extended, then the terminal apparatus can continue operation despite signal failures, but the responsiveness to new control instructions deteriorates
Solution Approach 1:
Route information is generated in advance with a validity period that extends beyond the expected execution time. This preliminary action ensures that the terminal apparatus can continue operation even if control signals are not received, while the system can still generate new route information to update the terminal apparatus when needed, balancing continuity and responsiveness

AI summary
A system capable of communicating with a terminal includes a processor and a transmitter. The processor is configured to generate a first control signal including a first target position to operate at least part of the terminal and generate a second control signal including a second target position to operate at least part of the terminal after an operation of the at least part of the terminal in accordance with the first target position. The transmitter is configured to transmit the first control signal to the terminal at a first timing and transmit the second control signal to the terminal at a second timing after the first timing. The first target position is farther than a position which the at least part of the terminal is to reach at the second timing.
