[0006] (1) Use the remote control to calibrate each ESC one by one, so that the strokes of each ESC are consistent and compatible with the stroke of the remote control; however, the operation process of this method is cumbersome, the calibration time is long, and the calibration effect is not good;
[0007] (2) The unified calibration of each ESC is realized by using the hub. Specifically, each ESC is connected to the hub, the ESC output signal line of the hub is combined into one and connected to the receiver, and the receiver establishes a wireless connection with the remote control One-time calibration of each ESC through the remote control; although this method simplifies the calibration steps, it needs to purchase an additional hub, and there are many connecting wires between each ESC and the hub, which is not easy for users to operate

Embodiment 1
[0062] This embodiment provides an ESC calibration method, refer to figure 1 , including the following steps:
[0063] S1: After the UAV is assembled and powered on, first calibrate the remote controller to obtain the standard stroke of the remote controller;
[0064] Since the stroke in the flight control module of the UAV is certain, if the remote controller is used together with the flight control module of the UAV, the stroke of the remote controller must be calibrated to the stroke of the flight control module of the UAV. The stroke of the aircraft flight control module is 1000us-2000us, therefore, it is necessary to standardize the stroke of the remote control to 1000us-2000us. It should be noted that the wireless signal includes a PWM signal, a PPM signal, etc. In this embodiment, the wireless signal mentioned is a PWM signal, and the range of the pulse width is 1000us-2000us.
[0065] see also figure 2 , where the remote control calibration method is as follows:

Embodiment 2
[0085] On the basis of Embodiment 1, this embodiment provides an ESC calibration system, refer to Figure 4 , including a remote controller, a drone and a ground station, the drone is equipped with a drone flight control module and a receiver wirelessly connected to the remote controller, the receiver is connected to the drone flight control module, without The man-machine flight control module is connected with the ground station;
[0086] Wherein, the remote controller is used to send the ESC calibration request signal and the wireless signal corresponding to the throttle of the remote controller to the receiver; the receiver is used to receive the wireless signal from the remote controller and transmit the wireless signal to UAV flight control module;
[0087] The UAV flight control module is used to generate the ESC calibration command, read the ESC calibration command and determine to enter the ESC calibration mode, so as to complete the throttle stroke calibration of ea...

Abstract
The present invention relates to the unmanned aerial vehicle technology field, especially to an electronic speed control calibration method. The method comprises the following steps: after an unmanned aerial vehicle complete assembling and is electrified, a remote controller is calibrated to obtain the standard stroke of the remote controller; an unmanned aerial vehicle flight control module obtains electronic speed control calibration request signals transmitted by the remote controller and generates an electronic speed control calibration instruction according the electronic speed control calibration request signals; after outage is performed and then power-on is started, the unmanned aerial vehicle flight control module reads the electronic speed control calibration instruction and determine that an electronic speed control calibration mode is accessed; and the unmanned aerial vehicle flight control module enters the electronic speed control calibration mode and takes each electronic speed control throttle stroke as the standard stroke of the remote controller. The electronic speed control calibration method and system simplify the operation process and complete calibration of each electronic speed control at one time so as to save the calibration time, overcome the problem of the complex operation caused by electronic speed control calibration step by step in the current operation method and simplify the operation with no need for extra calibration devices.
Description
technical field [0001] The present invention relates to the technical field of unmanned aerial vehicles, in particular to an electrical adjustment calibration method and system. Background technique [0002] Multi-rotor drones, also known as multi-axis aircraft, are controlled by three or more independent power systems, each power system includes a motor, an electric regulator, and a propeller. [0003] ESC, that is, an electronic governor, is used to convert the control signal of the flight controller (flight controller) into a current signal, thereby controlling the speed of the motor so that the motor runs at the rotation speed requested by the flight controller. [0004] As the ESCs leave the factory, the travels of the ESCs are inconsistent. If the ESCs are directly assembled in the power systems of the multi-rotor UAV, it is easy to affect the flight status of the aircraft. In addition, the ESCs need to be suitable for the travel of the remote control; In order to mak...
