Unmanned aerial vehicle risk-avoid flight data recording device and method

Abstract

The invention discloses an unmanned aerial vehicle risk-avoid flight data recording device and method. The method comprises the steps that components with little power consumption are adopted to form an independent and complete flight data recording device, a power supply is provided for the flight data recording device through an independent rechargeable power supply, and then the purpose of not occupying resources of an existing unmanned aerial vehicle automatic drive system is achieved; the independent and complete flight data recording device is internally provided with an induction system, a main control chip and a storing and transmitting device, and a judging unit is included and used for judging whether an unmanned aerial vehicle body enters a no-fly zone or not according to location information, obtained by a GPS interface, of the unmanned aerial vehicle body, further calculating the distance that the unmanned aerial vehicle body enters the no-fly zone, judging whether the distance is larger than a preset distance or not and controlling the unmanned aerial vehicle body to return according to a current flight route or controlling the unmanned aerial vehicle body to land. According to the unmanned aerial vehicle risk-avoid flight data recording device and method, the purpose of not influencing a data output interface protocol of an inherent sensor data bus of an unmanned aerial vehicle is achieved.

Description

technical field [0001] The invention relates to unmanned aerial vehicle control technology, in particular to an unmanned aerial vehicle flight data recording device and method. 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. [0004] When drones are operating in ...
