Problems solved by technology
The principle basically uses dual autopilots for safety precautions, which are generally only used by high-precision drones or large-scale model aircraft that cost more than 1 million yuan, and have not been applied to ordinary drones.
In addition, the price of the dual autopilot itself is very high, and the main function is only used when switching, not to add more functions in terms of safety, and the application range is narrow

Embodiment Construction
[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0017] See Figure 1-2 , The present invention provides a technical solution: a method for the safety and redundancy of the UAV autopilot, which includes setting two or more IMUs in the UAV autopilot, and when one IMU fails, the other IMU can be responsible for it. Its function, if the power of the six-axis is redundant, it can still fly when a single motor lacks power. When the aircraft is subjected to large vibrations or is not placed ...

The invention discloses a safe redundant method for an unmanned aerial vehicle automatic autopilot. The method comprises the following steps that: two or more groups of IMUs are arranged in an unmanned aerial vehicle autopilot; when one IMU fails, the other IMU can bear the function of the IMU; if six shafts are redundant in power, the unmanned aerial vehicle can still works when one motor has nopower; when the unmanned aerial vehicle suffers from large vibration or is not horizontally placed, IMU abnormity can be displayed during power-on self-test; at the moment, the IMUs need to be calibrated again. To be specific, a remote controller of an unmanned aerial vehicle is turned on, and App connection is performed; the unmanned aerial vehicle is placed on a horizontal table board; and access to App is carried out, flight control parameter setting, sensor, and IMU calibration are turned on. The invention further comprises a safety redundant device for an unmanned aerial vehicle autopilot; the unmanned aerial vehicle control redundant backup module comprises a starting module and an air pressure sensor, a computer is in wireless connection with a remote control device, and the remotecontrol device is in wireless connection with the starting module and the air pressure sensor.
Description
Technical field [0001] The invention relates to the technical field of UAV autopilots, in particular to a safety redundancy method for UAV autopilots. The invention also relates to a safety redundancy device for UAV autopilots. Background technique [0002] With the development of science and technology, drone technology has been greatly developed, and drone technology has also begun to be applied in various fields. At the same time, unmanned aerial vehicle technology is also developing rapidly, and various new technologies have emerged and gradually applied to unmanned aerial vehicles. UAVs have broad applications in disaster prevention and rescue, scientific investigations, wind power inspections, industrial-grade environmental protection and other fields. The flight control system of UAVs is an important part of UAVs. And it plays an important role in practicality. Especially in industrial drones, the manufacturing cost of industrial drones is high, especially for fixed-wing...
