A flight control system based on mobile phone

Abstract

The invention relates to a flight control system based on a mobile phone. The control process is: load the flight control application program on the smart phone, and then install the smart phone on the drone; if the communication between the integrated flight control unit and the smart phone is normal, enter the flight control system Mode selection; when dual-flight control mode is selected, if the self-test of the mobile phone terminal in remote control mode passes, the user sends an instruction, and the drone runs; compare the calculation output results of the flight control application program with the flight control program calculation output results of the integrated flight control unit, If the data output by the flight control application program is reasonable, the power unit executes the instructions of the smart phone; various sensors perceive and collect data separately, and the smart phone fuses its own sensor data with the sensor data on the integrated flight control unit and sends them back to the integrated flight control unit. control unit. In the dual-flight control mode, the present invention uses the sensor resources of the mobile phone itself to perform flight control calculations. When the flight control at the mobile phone terminal fails, the integrated flight control unit takes over to control the landing and ensure flight safety.

Description

technical field [0001] The invention relates to a UAV flight control technology, in particular to a mobile phone-based flight control system. Background technique [0002] At present, there are various types of drones on the market, and their flight controllers are similar with minor differences. Most of them are based on weaker microcontrollers with weaker computing capabilities, and their edge computing capabilities are weaker, unable to handle some complex computing requirements in real time, such as visual computing. In recent years, some drone products have used a dedicated video processing unit (VPU, Video Processing Unit) to process visual data and assist the flight control of the drone. Today's smartphones are generally equipped with sensors such as inertial measurement units, barometers, and GPS positioning modules required for UAV flight control, and current smartphones generally have strong computing resources, which can be used for large-scale computing Task. ...

AI Technical Summary

Problems solved by technology

[0003] Therefore, it is possible to apply sensors such as inertial measurement units, barometers, and GPS positioning modules of smartphones to drones, but currently there is no flight control system that can integrate smartphones and drones into one. see the report
