Remote Support Terminal Selection for Moving Body Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In remote support systems using multiple mobile terminals, it is challenging to accurately determine which terminal is performing the support, leading to potential confusion and inefficiencies in control signal management.
Innovation Solution
A control device on the moving body selects a support terminal based on priority parameters such as distance or communication intensity from multiple mobile terminals, ensuring that the appropriate terminal is chosen for remote support, and includes a sub communication terminal for displaying images from the selected terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple mobile terminals transmit support signals simultaneously, then the system can receive backup support options, but it becomes difficult to determine which terminal should perform the remote support
Solution Approach 1:
The control device determines terminal selection priority by comparing communication parameters such as reception signal strength or transmission delay between the control device and multiple mobile terminals. The terminal with the optimal parameter value (strongest signal or lowest delay) is selected as the support terminal, providing an automatic, objective selection mechanism that resolves the contradiction between having multiple backup options and maintaining clear selection criteria
2Reliability
If the system accepts support signals from multiple terminals, then redundancy is improved, but control signal management becomes complex and inefficient
Solution Approach 1:
The system extracts and identifies a single primary support terminal from multiple potential terminals based on communication parameters. By selecting one terminal as the primary support terminal, the system simplifies control signal management while maintaining the ability to receive signals from multiple terminals for redundancy purposes. The control device processes and prioritizes signals from the selected terminal, reducing management complexity
3Duration of action of stationary object
If remote support switches between terminals, then continuous support is maintained, but the switching process may cause control instability
Solution Approach 1:
The control device performs preliminary determination of terminal selection priority before actual terminal switching occurs. By pre-establishing the priority order based on communication parameters and having a predetermined terminal ready to take over, the system can switch terminals smoothly without causing control instability. The next available terminal in the priority order is prepared in advance to assume control when needed

AI summary
A control device is mounted on a moving body that receives a remote support based on a support signal transmitted from any one of a plurality of mobile terminals via wireless communication. The control device includes a communication device configured to perform the wireless communication with the plurality of mobile terminals, one or more processors. The one or more processors are configured, when receiving the support signal from each of the plurality of mobile terminals, to select a support terminal in accordance with priority based on a parameter of each of the plurality of mobile terminals. The support terminal is a mobile terminal that performs the remote support.
