Unmanned aerial vehicle communication method based on TCP and UDP

Abstract

The invention discloses an unmanned aerial vehicle communication method based on a TCP and a UDP. The method comprises the steps that S1, a client establishes a TCP connection with a server, wherein the client is an unmanned aerial vehicle or a ground control station; S2, encrypted TCP authentication login is carried out between the client and the server through the TCP connection, a TCP session is established, and first data is exchanged on the TCP session, wherein the first data includes parameter setting data of the unmanned aerial vehicle; and S3, encrypted UDP authentication login is carried out between the client and the server through the TCP connection, a UDP session is established, and second data is exchanged on the UDP session, wherein the second data includes one or more of control data, position data, real-time audio data and real-time video data of the unmanned aerial vehicle. According to the communication method disclosed by the invention, the advantages and disadvantages of the TCP and the UDP are well considered; the problem of low efficiency or data loss caused by single use of one communication protocol in the past is avoided; and the reliability and efficiencyof communication are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of communication, and mainly relates to a communication method for an unmanned aerial vehicle based on TCP and UDP. Background technique [0002] Almost all of the current UAV communication technologies are based on the TCP / IP protocol, which mainly uses the UDP protocol and the TCP protocol. The UDP protocol is a connectionless transport layer protocol that provides simple and unreliable transmission information transmission services. Based on UDP The communication speed of the protocol is fast, but the reliability is low, and the TCP protocol is a connection-oriented, reliable, byte stream-based transport layer communication protocol, but the efficiency is low, so either of the two is used alone It is difficult to balance transmission efficiency and data security and reliability. Contents of the invention [0003] The purpose of the present invention is to provide a UAV communication method based on TCP...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a UAV communication method based on TCP and UDP to address the defects of the existing methods, which takes into account the advantages and disadvantages of TCP and UDP, and avoids the disadvantages of using one of the communication protocols alone in the past. Inefficiency or data loss problems, greatly improving the reliability and efficiency of communication
