Embodiment

[0023] During specific implementation, the present invention is implemented according to the following steps:

[0024] a. Selection of sensors: use a three-axis gyroscope to sense the angular velocity signal of the UAV installed with the recording device in three dimensions in three-dimensional space, and send it to the main control chip 1; use a three-axis acceleration sensor to sense the UAV with the recording device installed The three-dimensional acceleration signal of the drone in the three-dimensional space is sent to the main control chip; the three-axis geomagnetic sensor is used to sense the three-dimensional geomagnetic signal of the drone installed with the recording device in the three-dimensional space, and sent to the main control chip; The air pressure temperature sensor 3 senses the atmospheric pressure signal and temperature signal of the UAV installed with the recording equipment in the three-dimensional space, and sends it to the main control chip; uses t...

Abstract

The invention discloses a flight data recording method and device for small / medium-size unmanned planes. According to the method, components with low power consumption constitute an independent and complete flight data recording device, an independent rechargeable power supply is utilized to supply power to the flight data recording device, thereby achieving the goal of not occupying the resources of the existing unmanned plane autopilot system; and the independent and complete flight data recording device is provided with a sensor, a main control chip and a storage and transmission device, thereby achieving the goal of not influencing the data output interface protocol of the inherent sensor data bus of the unmanned plane. The method and device can not influence the structure of the existing unmanned plane autopilot system, and thus, can not influence the flight control performance. The system has the advantages of low cost of hardware circuits and small size; and a complete unmanned plane black box system is formed after installing a protective casing, and thus, the system is convenient for installation and operation and has favorable applicability and higher use value.

Description

technical field [0001] The invention relates to a method and device suitable for recording flight data of small and medium-sized drones, and belongs to the technical field of flight data recording. Background technique [0002] A standard recording device on modern aircraft is called a black box. Through the black box, people can analyze the flight data of the aircraft during the entire flight process. According to the flight data recorded in the black box, the hidden dangers of the aircraft can be eliminated in advance to avoid accidents. Once an accident occurs, the cause of the accident can also be analyzed through the flight data recorded in the black box. [0003] Most of the existing black boxes are used for manned aircraft. Although some can be used for unmanned aerial vehicles, they are not suitable for small and medium-sized unmanned aerial vehicles due to their large size and weight and occupying the resources of the aircraft's autopilot system.
