Preflight sound control equipment checking method and system for unmanned aerial vehicle

The invention provides a preflight sound control device checking method and system for an unmanned aerial vehicle. The method comprises the following steps: a sound control device is plugged into an autopilot of the unmanned aerial vehicle through serial ports; whether the unmanned aerial vehicle starts the sound control mode or not is judged, if unmanned aerial vehicle starts the sound control mode, the preflight checking is carried out by adopting the sound control manner, otherwise, the preflight checking is carried out by adopting a manual manner; the autopilot receives preflight checking voice instructions sent by checking personnel through the sound control device, performs analog-digital conversion on the preflight checking voice instructions to generate corresponding control instructions, starts the flight check according to the control instructions, automatically checks multiple built-in check items in sequence until all the check items are checked, and plays a check completion voice prompt for the checking personnel through the sound control device. According to the invention, the sound control is adopted, and the preflight checking can be completed by one person, so that the working efficiency and checking accuracy are improved.
