Embodiment Construction

[0016] A preferred embodiment of the present invention is described as follows in conjunction with accompanying drawing:

[0017] Referring to Fig. 1, the steering gear control device of the small unmanned aerial vehicle is connected in series between the receiver 5 and the steering gear 6, and the six-way steering gear control signal 13 input from the receiver 5 is input into the CPLD 8, and the CPLD 8 is based on the obtained six-way steering gear The control signal 13 outputs the servo control signal 12 to the signal sampling port of the single chip microcomputer 1 . The three-way switching control mode signal 14 input from the receiver 5 is input into the CPLD 8, and the CPLD 8 outputs the mode switching signal 11 to the signal sampling port of the single-chip microcomputer 1 according to the obtained three-way switching control mode signal 14. The single-chip microcomputer 1 communicates with the host computer through the serial port 2, and sends the information of the ob...

Abstract

The present invention provides a steering engine control device of small-type unmanned vehicle. The circuit mechanism is the connection of a singlechip and a complex programable logic device, the singlechip connects a host link unit via a Serial Peripheral Interface or a Universal Asynchronous Receiver Transmitter, the CPLD is connected with a receiver, steering engine control signal output by CPLD is connected to the steering engine via a low pass filter. The invention reduces the design complexity of the system, and enhances the late modify signal performance of the system. The aim of the modifying system only needs modifying softer of the system, but not modifies hardware of the system. The invention adopts a modularization design, high credibility, simple testing and lower cost.

Description

technical field [0001] The invention relates to a steering gear control device for a small unmanned aerial vehicle, in particular to a steering gear control device for an ultra-small unmanned helicopter, belonging to the technical field of ultra-small unmanned aerial vehicles. Background technique [0002] The steering gear control system is an important device in the UAV. It is the interface between the flight control computer and the steering gear, and is used to directly operate the steering gear to control the operating state of the aircraft. Due to the small size and light weight of small unmanned aerial vehicles, they are very vulnerable to environmental interference during flight and destroy their autonomous flight. At the same time, small unmanned aerial vehicles often have complex electromagnetic environments, which can easily cause the control system to lose control, and there is often a risk of crashing. In order to avoid flight accidents, it is required that the ...
