Dual-Link Drone Communication Switching for Signal Interruptions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Logistics drones face communication reliability issues due to signal interruptions, leading to potential loss of control and safety hazards during flights, especially in rural areas with sparse base stations and uneven signal coverage.
Innovation Solution
A dual communication link system is established using a backup module, allowing data transmission to switch to a secondary network when the primary link is interrupted, ensuring continuous and stable communication between the drone and the ground station, thereby enhancing communication reliability while controlling costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single communication link is used for drone-ground communication, then the device complexity is low, but the communication reliability deteriorates due to signal interruptions
Solution Approach 1:
The communication system is segmented into multiple independent communication links (first communication link and second communication link), each capable of operating autonomously. The drone processor divides communication tasks across these segments, switching between them based on signal quality, thereby improving overall reliability without requiring complete system redesign
Solution Approach 2:
The system dynamically changes operational parameters by monitoring signal quality metrics (such as signal strength and interference levels) and switching between different communication links based on these parameter variations. This allows the system to adapt to changing environmental conditions and maintain reliable communication
2Reliability
If multiple communication links are established for backup, then the communication reliability is improved, but the device complexity increases
Solution Approach 1:
Multiple communication modules are designed with universal functionality, where each module can operate independently as a complete communication channel. The first and second communication links both具备 full capability to transmit control instructions and telemetry data, allowing any module to take over seamlessly without requiring specialized backup hardware
Solution Approach 2:
The communication system implements self-service through automatic monitoring and self-switching mechanisms. The drone processor continuously monitors signal quality and automatically switches between communication links without external intervention, reducing the need for complex manual control systems and simplifying overall system architecture
3Reliability
If active monitoring and switching between communication links is implemented, then the communication reliability is improved, but the energy consumption increases
Solution Approach 1:
Instead of continuous monitoring, the system employs periodic sampling of signal quality parameters at optimized intervals. The drone processor checks communication link status at predetermined time intervals or after specific trigger events, reducing unnecessary processing while maintaining reliable detection of signal degradation
Solution Approach 2:
The system performs preliminary actions by maintaining standby communication links with minimal active processing. Backup communication modules remain in low-power states with basic monitoring enabled, allowing rapid activation when needed without requiring full operational power consumption during normal single-link operation

AI summary
A drone communication system and method. The system includes a first communication module; a second communication module; and a drone processor electrically connected to the first communication module and the second communication module respectively; and configured to receive and send a heartbeat packet and communication data through a first communication module and a first communication network, so as to communicate with a first communication port of a server; receive and send communication data through a second communication module and a second communication network, so as to communicate with a second communication port of a server. A receiving condition of the heartbeat packet is used to determine whether to use the communication data received by the first communication network or the second communication network.
