Autonomous Moving Body Priority Control for Route Conflict Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing management systems for autonomous moving bodies, such as drones, do not effectively consider the positional relationship between flying bodies or other autonomous moving bodies, leading to challenges in setting their behavior and avoiding interference.
Innovation Solution
A management system that includes a priority/subordination comparing section or receiving section within autonomous moving bodies, allowing them to compare or receive priority/subordination degrees with other moving bodies. This enables autonomous decision-making for route selection and other actions without the need for direct communication with other moving bodies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If autonomous moving bodies rely on direct communication with other moving bodies for route selection, then coordination between bodies can be achieved, but the system becomes vulnerable to communication failures and environmental interference
Solution Approach 1:
Each autonomous moving body independently determines its own priority/subordination degree and compares it with others to make autonomous decisions about route selection and behavior adjustment, without relying on centralized control or complex inter-body communication protocols
Solution Approach 2:
The system pre-assigns priority/subordination degrees to moving bodies based on predetermined criteria (such as vehicle type, cargo importance, or scheduled time), enabling autonomous decision-making before communication failures or environmental disruptions occur
2Adaptability or versatility
If a centralized management system controls all autonomous moving bodies, then coordination and conflict avoidance can be achieved, but the system requires continuous communication and becomes less adaptable to local conditions
Solution Approach 1:
Autonomous moving bodies independently compare their priority/subordination degrees with others and autonomously adjust their behavior and route selection based on these comparisons, eliminating the need for continuous centralized communication while maintaining adaptability to local conditions
Solution Approach 2:
The centralized control function is segmented and distributed to individual moving bodies, with each body maintaining local decision-making capability based on its assigned priority level, reducing communication dependency while preserving coordination
3Reliability
If autonomous moving bodies continuously monitor and communicate with each other to avoid interference, then collision avoidance can be achieved, but energy consumption and system complexity increase
Solution Approach 1:
Instead of continuous monitoring and communication, the system uses discrete priority/subordination degree comparisons at critical decision points (route selection, conflict situations), reducing energy consumption while maintaining adequate collision avoidance capability
Solution Approach 2:
Each moving body autonomously determines its priority level and makes independent decisions about route selection and conflict avoidance based on predetermined criteria, eliminating the need for continuous energy-consuming communication protocols

AI summary
A management system (10) comprises a movement management unit (28) that communicates via a communication device with a plurality of moving bodies (26) including an autonomous moving body (26e) provided with an autonomous control unit (130) for moving autonomously, and that manages the movement of the plurality of moving bodies. The movement management unit comprises a priority/subordination determination unit (64) that determines the degree of priority/subordination relating to the respective movements of the plurality of moving bodies on the basis of individual information of the moving bodies. The autonomous moving body comprises: a priority/subordination comparison unit (132) that compares another priority/subordination degree, which is a degree of priority/subordination determined by the priority/subordination determination unit for another moving body (26o) that is a moving body, from among the plurality of moving bodies, different from the autonomous moving body, and the host priority/subordination degree, which is a degree of priority/subordination determined by the priority/subordination determination unit for the autonomous moving body; or a priority/subordination reception unit (104) that receives the comparison results of the host priority/subordination degree and the other priority/subordination degree obtained by comparisons by the moving body management unit.
