Unmanned aerial vehicle control system

Abstract

The invention discloses an unmanned aerial vehicle control system. The system comprises a main processor powered by a power supply module arranged in an unmanned aerial vehicle. The main processor is connected with a posture and heading system, a barometric altitude sensor, a GPS module, an ultrasonic sensor, an airborne remote sensing device, an information storage module, an ultrasonic ranging module and an electronic speed governor. The barometric altitude sensor and the GPS module are connected with the main processor after being compared. The information storage module stores no-fly zone information. The posture and heading system is directly connected with the information storage module through an instruction calling program. The ultrasonic ranging module is directly connected with the posture and heading system through the instruction calling program. The main processor is connected with a shooting device through a shooting control system. The main processor is connected with the information processing system of a ground station through digital microwave transmission. According to the structure, hovering and positioning data are accurate; the communication speed is very fast; the communication stability is improved; and the problem that the unmanned aerial vehicle cannot be controlled is avoided reliably.

Description

technical field [0001] The invention relates to a control technology of an unmanned aerial vehicle, in particular to an unmanned aerial vehicle control system. Background technique [0002] With the development of society, UAVs are gradually popularized in people's daily life and widely used in various fields (such as disaster prevention and early warning, geographic mapping, meteorological observation, road navigation), but the existing UAV control system is due to The control method is unreasonable, and there are still the following defects. On the one hand, the positioning accuracy is not high, the hovering reliability is poor, and there is a greater risk. On the other hand, the signal is easy to lose, resulting in uncontrollable control. On the other hand, it is easy to enter to no-fly areas and collision obstacles. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a UAV control system with accurate positionin...
