Remote Control out of control protection：From the perspective of safety, the current remote control is
still irreplaceable for plant protection drone. In order to ensure the safety of drone flight, and for the actual
demand of large area self-spraying, the more complete remote control safety protection strategy is designed. The
protection of out of control of the remote control can be set on the ground station software,the setting is designed
only for "full autonomous mode, manual mode (high/fixed mode) and ab mode are default open and cannot be
closed ；
Data link fault protection：In order to improve the ease of use, we set the ground station as a
non-synchronous necessary device, which means that during the actual flight of the drone, the state of the drone
can be observed through the ground station, or the data link can be disconnected, and the working condition can be
determined by the state of the drone and the indicator light.In order to prevent the data transmission link instability
from adversely affecting the actual operation, the data link fault protection is set to be effective only in the full
autonomous mode and the remote control signal is lost；
Low Voltage Protection：We provide voltage protection based on the modifiable voltage value, that is, the
user can correct the voltage value measured by the flight control via the ground station (if there is a difference
between the actual value and the measured value, the measurement value can be corrected by this function), the
flight control detects the single-chip voltage and implements the protection；
Area Limit Protection：In some specific cases, it is necessary to limit the flight range of the drone.our
system provides flight restrictions of two-dimensional and three-dimensional space, namely height and distance
limits, to ensure the safety of the drone flight.

Remote
Control
When the joystick is returned to the center, the drone
will maintains its attitude, and the throttle can be set to a
height, but it cannot achieve precise fixed-point hover,
so manual correction is required
