Checkpoint Status Reporting for Inspection Route Communications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned vehicles deployed for field inspections often miss checkpoints or fail to perform tasks due to adverse conditions, and existing communication systems lack efficient means to report task status and receive instructions, especially in areas with limited data coverage.
Innovation Solution
A wireless communication system that allows unmanned vehicles to identify and report task statuses at checkpoints, with a base station receiving and processing these reports to determine the next checkpoint, enabling real-time monitoring and task re-attempts as needed, using non-orthogonal multiple access (NOMA) signature sequences for efficient data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If unmanned vehicles operate in areas with limited data coverage, then inspection coverage is improved, but communication reliability deteriorates
Solution Approach 1:
The system pre-assigns NOMA signature sequences to unmanned vehicles before they enter coverage areas with limited data connectivity. This preliminary configuration enables the vehicles to immediately report task statuses using preallocated resources, eliminating the need for real-time resource negotiation and ensuring reliable communication even when data coverage is limited.
Solution Approach 2:
NOMA signature sequences serve as an intermediary communication mechanism between unmanned vehicles and the base station. These signature sequences enable direct identification and reporting of task statuses without requiring traditional data channel establishment, thus bridging the communication gap in areas with limited data coverage.
2Productivity
If traditional communication systems are used for checkpoint reporting, then system complexity is reduced, but reporting efficiency deteriorates
Solution Approach 1:
The patent replaces traditional mechanical data transmission protocols with NOMA-based signature sequence identification. Instead of establishing complex data channels and performing lengthy handshaking procedures, the system substitutes this with a simplified process where vehicles transmit task status information modulated on pre-assigned signature sequences, enabling rapid reporting with minimal processing overhead.
3Manufacturing precision
If real-time monitoring is implemented, then task completion accuracy is improved, but data transmission requirements increase
Solution Approach 1:
The system extracts only the essential task status information (completed, pending, failed) from full inspection data and reports only this condensed status to the base station. This extraction approach enables real-time monitoring of task completion accuracy while minimizing data transmission volume, as detailed inspection data can be processed locally or transmitted later when connectivity is available.
