Problems solved by technology

However, the sensors carried by projection mobile phones are limited by cost and usage, and often lack one or more sensors required by the UAV flight control system; even if a certain sensor is equipped, its sensing accuracy or sampling frequency is often low , so the control effect of the flight control system based entirely on the projection phone's own sensors is poor

Abstract

The present invention discloses an unmanned aerial vehicle flight control system based on a projection mobile phone. The system comprises an unmanned aerial vehicle body, and a projection mobile phone, a sensing servo controller and a flight execution mechanism which are fixedly arranged on the unmanned aerial vehicle body and are connected to each other; the projection mobile phone is internallyprovided with a flight control program; the projection mobile phone is internally provided with a gyroscope, an accelerometer, a GPS and a magnetic field sensor; the sensing servo controller is internally provided with a microcontroller, an intelligent identification module, a GPS, a timer, an AD sampler, an infrared sensor, an air pressure sensor, an ultrasonic sensor, a light stream sensor, a magnetic field sensor, an external assistant sensor of the gyroscope; and the sensing servo controller is internally provided with a PWM generation timer connected with the flight execution mechanism. The unmanned aerial vehicle flight control system achieves saving of system resources, improvement of stability and easy control.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle flight control system based on a projection mobile phone. Background technique [0002] UAVs are widely used in aerial photography, military, agriculture and other fields, and are now gradually expanding to the field of personal consumption. For example, the Spark drone released by DJI, a leading drone company, in June 2017 is small in size and light in weight, and mainly meets the needs of ordinary people for taking selfies. For small UAVs in the personal consumption field, the control modes mainly include remote control and mobile APP control. DJI's Spark UAV supports remote control and mobile APP control, which can not only meet the needs of close-range selfies, but also realize the needs of mid-range aerial photography. The DOBBY pocket drone of Zero Degree Intelligent Control only supports mobile phone APP control, including soma...
