Drone Crash Detection via Motor Status Alarm Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Crashed drones are difficult to locate rapidly due to the need for manual search, reducing the probability of recovery.
Innovation Solution
A drone control method and device that monitors the status of each power motor, determines if the drone is crashed, and activates an alarm to facilitate rapid location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If manual search is used to locate crashed drones, then no additional alarm system is needed, but the time to locate crashed drones increases and recovery probability decreases
Solution Approach 1:
The system performs preliminary monitoring of power motor running status during normal flight operations. Before the drone actually crashes, the system has already been collecting data on motor performance, which enables immediate detection of crash conditions without requiring additional post-crash search time.
Solution Approach 2:
The system establishes a feedback loop by continuously monitoring power motor status and comparing it against expected operational parameters. When abnormal conditions are detected indicating a crash, the system immediately activates the alarm function, providing real-time feedback about the drone's state to enable rapid location.
2Productivity
If alarm function is added to crashed drone, then location speed increases, but device complexity increases
Solution Approach 1:
The alarm system is designed to serve multiple functions: it can alert operators during abnormal flight conditions, indicate battery status, and specifically signal crash events. By making the alarm multi-functional, the patent avoids adding dedicated hardware solely for crash detection, thereby limiting the increase in device complexity while maintaining high productivity in locating crashed drones.
Solution Approach 2:
The drone performs self-detection of crash conditions by monitoring its own power motor status. The system automatically determines when a crash has occurred and activates the alarm without requiring external detection equipment or manual intervention, enabling the drone to service its own monitoring needs.
Data Source
AI summary
This application discloses a drone control method and device and a drone and pertains to the technical field of drone control. The method includes: monitoring a running status of each power motor in a drone; determining according to the running status of each power motor whether the drone is in a crashed state; and controlling the drone to alarm when determining that the drone is in the crashed state. The drone control method and device and the drone can rapidly locate a crashed drone, greatly increasing the probability of finding back the crashed drone.
