The implementation mechanism of ensuring the safety of drone flights through the self-repair function of the flight control system

Drones, as the perfect combination of artificial intelligence technology and flight technology, are gradually penetrating into various industries, such as agriculture, surveying and mapping, rescue, and logistics. However, due to various reasons, malfunctions or damages during the actual flight of drones seriously affect the efficiency of their use, and even lead to personal injuries or property losses. Therefore, ensuring the safety of drone flights and improving their reliability and safety have become urgent issues to be solved in the field of drone applications. The self-repair function of the flight control system has become an effective way to solve this problem.

One, Definition of Self-repair Function in Flight Control System

The self-repair function of the flight control system refers to a technology that allows drones' flight control systems to diagnose, locate, isolate, and repair failures or damages through their own mechanisms, thereby restoring the flight function of drones. The implementation of self-repair functions requires the flight control system to have strong fault diagnosis capabilities, accurate fault location capabilities, rapid fault isolation capabilities, and effective fault repair capabilities.

Two, Implementation Mechanism of Self-repair Function in Flight Control System

1. Fault Diagnosis and Location: The flight control system performs fault diagnosis and location through built-in hardware devices such as sensors, actuators, and controllers, as well as real-time monitoring data streams. For example, when drones exhibit abnormal phenomena such as vibration and tilt during the flight, the flight control system will detect abnormal signals through sensors, and then judge that a certain component inside the flight control system may have failed, and then locate the fault through fault diagnosis algorithms.

2. Fault Isolation and Repair: The flight control system achieves fault isolation and repair through hardware redundancy, software redundancy, fault isolation, and other technologies. For example, when the flight control system detects a failure in a certain component, it can transfer the control authority of the component to other normal working components through hardware redundancy technology, thereby achieving fault isolation; at the same time, through software redundancy technology, transfer the control authority of the failed component to other normal working components, thereby achieving fault repair.

3. Self-learning and Adaptation: The flight control system achieves self-repair through self-learning and adaptation technology. For example, when the flight control system encounters a failure that has never been encountered during the flight, it can learn and master the diagnostic and repair methods of the failure through self-learning technology, thereby achieving self-repair; at the same time, through adaptive technology, adjust the parameters of the flight control system according to the changes in the flight environment of the drone, improve the adaptability and reliability of the flight control system.

Three, Application of Self-repair Function in Flight Control System

The application of self-repair functions in flight control systems can significantly improve the flight safety and reliability of drones. For example, in the agricultural field, the self-repair function of the flight control system can effectively prevent failures during the flight of drones, thereby ensuring the normal sowing and harvesting of crops; in the surveying and mapping field, the self-repair function of the flight control system can effectively prevent failures during the flight of drones, thereby ensuring the accuracy of surveying and mapping data; in the rescue field, the self-repair function of the flight control system can effectively prevent failures during the flight of drones, thereby ensuring the safety of rescue personnel.

Four, Conclusion

The implementation of the self-repair function of the flight control system is an important means to ensure the flight safety of drones, improve the reliability and safety of drones. In the future, with the continuous development of flight control system technology, the application of self-repair functions in flight control systems will become more extensive, bringing more possibilities to the application fields of drones.
