Flight remote controller suitable for unmanned plane

Abstract

The invention discloses a flight remote controller suitable for an unmanned plane, which comprises a control chip, a switch, a rocker mechanism circuit, a signal adjustment circuit, an LCD display circuit, a keyboard control circuit, a serial port communication circuit and a high-fidelity digital speech encoding-decoding circuit. The high-fidelity digital speech encoding-decoding circuit ensures the duplex high-fidelity speech communication between an in-vehicle measuring and controlling platform and an out-vehicle measuring and controlling staff without increasing radio communications to interfere a measuring and controlling data chain of the unmanned plane; besides, the digital speech outputs are digital signals directly to provide conveniences for sending codes of the measuring and controlling platform, and the measuring and controlling information sent by the measuring and controlling platform uses high hop-speed spread spectrum measuring and controlling data chain to ensure the high anti-interference and anti-interception performance of signals so as to improve the reliability, the economical efficiency and the maneuverability of the unmanned plane.

Description

technical field [0001] The invention belongs to the technical field of drone remote control engineering, and in particular relates to a flight remote controller suitable for drones. Background technique [0002] Unmanned aerial vehicle (UAV) is a powered, controllable, capable of carrying a variety of mission equipment, performing a variety of combat missions and reusable UAV tactical aircraft. Due to its zero casualty risk and high mobility and other advantages, it has attracted great attention from the military of various countries. The flight process of the UAV is divided into three parts: takeoff, high-altitude flight and landing. The surrounding environment is relatively stable during the high-altitude flight stage, and there is no need to make too many adjustments to the flight speed and attitude of the aircraft. . However, during the take-off and landing stages, the speed of the drone changes greatly, the attitude adjustment is frequent, and the landing site is rela...

AI Technical Summary

Problems solved by technology

[0004] 1. There is no voice communication on the remote control of the model aircraft, which is not conducive to the communication between the test and control console inside the car and the controller outside the car

[0005] 2. The communication frequency band used by the remote control of the aircraft model is relatively fixed and open, so the anti-interference and anti-interception capabilities are poor and it is not suitable for military drones with high confidentiality requirements.

[0006] 3. It is necessary to install a wireless receiving module on the UAV to use the remote control of the model airplane, and the receiving module of the model airplane and the measurement and control station are bound to interfere with each other in a small space

[0010] 1. Analog voice is easy to be self-excited, and the call quality is not high

[0011] 2. The analog voice and digital measurement and control signals are on the same cable. In order to eliminate the mutual interference between digital and analog signals, the isolation layer inside the cable increases the cost of the cable, and the thicker cable is inconvenient to use.
