Unmanned aerial vehicle flight control method, device, equipment and storage medium

By employing an architecture where the main process and hot standby process work together, the problem of data loss and loss of control in the event of a software crash in the UAV flight control system is solved. This achieves low-latency data recovery and stable flight control of the UAV, reduces the risk of performing disconnection actions, and does not increase hardware costs.

AI Technical Summary

Technical Problem

Existing drone flight control systems cannot maintain data integrity when software crashes, leading to drone loss of control. Furthermore, existing solutions increase hardware costs or pose a risk of performing actions that cause the drone to lose connection.

Method used

An architecture is adopted in which the main process and the hot standby process work together. The hot standby process periodically monitors the survival status of the main process and retrieves and migrates backup data from shared memory to the restarted main process in case of an anomaly, ensuring the continuity of UAV flight control and data integrity.

Benefits of technology

It enables low-latency recovery of drones after software crashes, maintains the continuity of flight control, reduces the risk of performing disconnection maneuvers, and does not increase hardware costs.

Abstract

The invention discloses an unmanned aerial vehicle flight control method and device, equipment and a storage medium, and relates to the field of unmanned aerial vehicles, and the method comprises the steps: periodically monitoring the survival state of a host process through a hot standby process; when determining that the survival state of the host process is abnormal, acquiring backup data from a first preset position of a pre-configured shared memory; migrating the backup data to the host process; and after the host process is controlled to be restarted, running the backup data by using the host process so as to continuously control the unmanned aerial vehicle to continuously execute the flight operation. The system ensures that the system can immediately restart the host process and recover the function of the host process through the hot standby process through a dual-process hot standby architecture, so that the unmanned aerial vehicle is prevented from being out of control, backup data is migrated to the restarted host process at the first time, the data recovery degree is improved, the normal flight control state is recovered immediately after loss of communication, and the reliability of the unmanned aerial vehicle is improved. And the risk when the unmanned aerial vehicle executes the disconnection action is reduced.
