Embodiment Construction

[0014] Describe the present invention in detail below in conjunction with accompanying drawing:

[0015] figure 1 It is a functional block diagram of the present invention. The invention is mainly composed of a switching controller module, an airborne remote control transceiver module and a ground remote control transceiver module. The switching controller receives the PWM steering gear control signal from the automatic flight control system and the information of each sensor, and also receives the PWM steering gear control signal from the airborne remote control transceiver. The switching controller performs flight mode switching according to the autopilot / manual remote control flight judging rules preset in the controller. If it is switched to the automatic pilot mode, the PWM steering gear signal of the automatic flight control system is output to the steering gear of the unmanned helicopter to realize the automatic flight of the unmanned helicopter; if it is switched to ...

Abstract

The invention discloses a method for switching the automatic flight mode and the manual remotely-controlled flight mode of a miniature unmanned helicopter, and belongs to the field of automatic control of an aircraft. A switching controller module receives the PWM (pulse-width modulation) steering gear control signal and the sensor information of the flight control system of the miniature unmanned helicopter, judges the PWM steering gear control signal and the sensor information of the automatic flight control system according to the preset judgment rule, and switches the PWM steering gear control signal to the remotely-controlled PWM steering gear control signal from the automatic control signal if the PWM steering gear signal or the sensor information of the automatic flight control system is judged to be abnormal. The switching method adopted by the invention detects the flight condition of the miniature unmanned helicopter without intermittences, switches the automatic control flight mode into the manual remotely-controlled flight mode at once if the abnormity of the flight condition is detected, and informs operating personnel on the ground to remotely control the helicopter to fly and guide the helicopter to safely land.

Description

technical field [0001] The invention relates to a method for switching between automatic driving and manual remote control flight of a miniature unmanned helicopter, belonging to the field of automatic control of aircraft. Background technique [0002] Mini unmanned helicopter is a popular technology in the world today. Due to its small size, low cost, good flight maneuverability, and low requirements for take-off and landing sites, micro unmanned helicopters are widely used in civil fields such as aerial photography, atmospheric monitoring, traffic monitoring, resource exploration, agriculture, and battlefield reconnaissance, target surveillance, direct attack, Military fields such as communication relays have been widely used. However, the micro unmanned helicopter is a typical complex control system with nonlinear, multiple input and multiple output, strong noise, and strong coupling. Although some effective control methods have been proposed today, it is difficult to en...
