Embodiment Construction

[0057] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention and the accompanying drawings. Apparently, the described embodiments do not limit the present invention.

[0058] Such as figure 1 As shown, a UAV remote controller analysis signal method includes the following steps,

[0059] Step 1, signal conversion, captures the analog signal sent by the remote control, and converts the analog signal into the original digital signal;

[0060] Step 2, smoothing filter processing, adopting median filter method to carry out smooth filter processing to the original digital signal obtained in step 1;

[0061] Step 3, checking, adopting the CRC check algorithm to obtain the CRC check bit, generating a digital signal packet composed of the CRC check bit and the digital signal processed by the smoothing filter in step 2;

[0062] Step 4, data transmission, the remote controller sends ...

Abstract

The present invention belongs to the UAV control system and method. In order to solve the high requirements on the control ability of the hand-held wireless remote controller in the prior art, the control mode of the ground control station is difficult to make predictions and decisions when the UAV is affected by adverse environments. To solve the problem of quick response, a method for analyzing signals of a UAV remote control, a signal processing method and a system are provided. The processing method includes signal conversion, smoothing filter processing, verification, data transmission and verification, and the ground control station checks whether the CRC check digit and the local check digit are consistent to determine whether the data is correct. The processing system includes a ground control station, a remote control and a data processing module. The original ground control station or remote control controls the UAV, and the data processing module is introduced, which combines the real-time control of the ground control station and the remote control in emergencies. The advantage of being able to be controlled manually further ensures the control accuracy of the drone.

Description

technical field [0001] The invention belongs to an unmanned aerial vehicle control system and method, in particular to an unmanned aerial vehicle remote control analysis signal method, signal processing method and system. Background technique [0002] UAV is a kind of unmanned aircraft controlled by radio remote control equipment or autonomous program with its own power. At present, because of its wide application and cheap price, it has gradually entered the public's sight, coupled with the intelligent control algorithm Implantation, the function expansion of drones is becoming more and more abundant. At present, it is widely used in aerial photography, surveying and mapping, plant protection, micro selfie, express transportation, disaster rescue, wildlife observation, news reporting, power inspection and food photography, which greatly expands the use of UAV itself. Actively expanded industry applications and UAV technology. [0003] At present, most UAV systems use hand...
