A large UAV remote control real-time transmission processing method

Abstract

The present invention provides a large UAV remote control real-time transmission processing method, including the following steps: step S1, setting the sending end and the receiving end for communication to have the same clock cycle; step S2, sending the data according to the set clock cycle at the sending end ; Step S3, the receiving end receives the data from the sending end, puts the received data into the buffer area, waits until the clock cycle arrives, performs data processing on the data in the buffer area, and calculates the sending end and the receiving end in each clock cycle of the receiving end The clock offset position Pn at the end; step S4, according to the calculated clock offset position Pn, judge the clock cycle speed of the sending end and the receiving end, and select the number loss processing logic or delay processing logic according to the judgment result. The invention solves the problem of data loss or delay increase due to clock cycle jitter and cycle deviation in asynchronous communication.

Description

technical field [0001] The invention relates to the technical field of remote control of drones, in particular to a method for processing real-time remote control of large drones. Background technique [0002] As a real-time control system, the large-scale unmanned aerial vehicle system needs to transmit control data through multiple terminals on the ground to accurately reach the unmanned aerial vehicle. Since each transmission link is asynchronous communication and has its own communication clock, More or less, there will be clock cycle jitter and cycle deviation in asynchronous communication. When the clocks at both ends move to the critical period, the receiving end cannot receive the sending end data accurately and timely, resulting in unnecessary data loss and control time. The delay increases until the clock moves out of the critical area. During this period, drone control will seriously affect the control of the drone and bring great safety hazards.
