Control method of remote control system and primary device

Abstract

The invention discloses a control method of a remote control system and a primary device. The method comprises the following steps: the primary device of the remote control system receives a first data packet sent by a slave device of the remote control system according to the first data rate, wherein the first data rate is determined through advance connection establishment of the primary device and the slave device; the primary device acquires position information of the slave device from the first data packet, and determines the straight line distance between the primary device and the slave device according to the position information of the slave device and the self position information; the primary device judges whether the straight line distance is within the straight line distance value taking interval corresponding to the preset first data rate; if the primary device judgment result is not, the slave device is notified to be adjusted as the second data rate so as to enable the primary device to communicate with the slave device according to the second data rate, thereby solving the disadvantage that the handling action is large in response delay and can be out of control since the unmanned aerial vehicle wireless remote control communication method adopts the fixed data rate to communicate at present.

Description

technical field [0001] The invention relates to the communication field, in particular to a control method and main equipment of a remote control system. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft controlled by radio remote control equipment and its own program control device. UAVs are responsible for tasks such as ground monitoring, target tracking, and military strikes. Because of their small size and strong flexibility, they play an extremely important role in the military and civilian fields. The radio frequency communication effect of the UAV directly determines the response delay of the control action and the maximum effective control distance of the UAV when performing tasks. At present, UAV radio frequency communication can be divided into uplink and downlink according to the direction of data transmission. The uplink mainly completes the transmission of remote control commands from the ground terminal to the UAV,...

AI Technical Summary

Problems solved by technology

Although the remote control radio frequency communication system with a fixed data rate will have a certain receiving sensitivity (for example: -89dbm), the fixed sensitivity will restrict the maximum effective control distance, because the receiving sensitivity and data rate are negatively correlated, so no one The maximum effective control distance of the machine is also negatively correlated with the data rate of radio frequency communication, and is limited by its fixed data rate, which also restricts the response delay of the control action, because the response delay of the control action is negatively correlated with the data rate of radio frequency communication. Related characteristics, when the remote control device is close to the aircraft, there will be a large control action response delay; when the remote control device reaches its maximum effective control distance from the aircraft, the aircraft may lose control

[0004] To sum up, the current method of wireless remote control communication for UAVs uses a fixed data rate for communication, which has the disadvantages of large delay in response to control actions and loss of control
