Embodiment Construction

[0045] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0046] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention relates to a throttle control method and device, a power system and an unmanned aerial vehicle. The method comprises the following steps: an electronic governor receives throttle signalsthrough a serial communication interface; throttle control data is extracted from the throttle signal; a motor control signal is generated for controlling the operation of the motor according to thethrottle control data; and the motor control signal is transmitted to the motor. The throttle signal received by the serial communication interface is a digital signal. In the transmission process, the interference is small, unlike the analog signal is susceptible to resistance and anti-interference, tolerance and anti-interference and other kinds of analog signal disturbance, which results in inaccurate data. Moreover, the serial communication mode can adopt higher baud rate, shorten the throttle control cycle, achieve throttle high-speed control, and increase the frequency of control.

Description

technical field [0001] The invention relates to the field of throttle control, in particular to a throttle control method, device, power system and unmanned aerial vehicle. Background technique [0002] With the development of technology and the continuous improvement of people's requirements for product performance, the upper control of more and more products requires higher control frequency, shorter control cycle, and even precise control. [0003] When the user operates the remote control, the user's operation signal of the remote control itself is sent to the flight control module, and the flight control module obtains the throttle signal of each ESC through calculation according to the user's operation signal and the attitude of the aircraft itself, and then transmits the throttle signal It is sent to the ESC through the serial interface, and the ESC calculates the throttle value, which can represent the speed of the motor controlled by the ESC. [0004] The ESC is th...
