Alternative solution AS1:
The travel measurement of the incremental
encoder is evaluated via the Micoc and a speed is determined. The
reel is driven by a DC motor, which is connected to the shaft and
the reel via a beam coupling. The ascencion is realized by a
freerun, in the descent a raised platform is used for landing to
guarantee the safe line guidance. A single battery with optocoupler
is sufficient.
Alternative solution AS2:
The travel measurement obtained by means of a potentiometer is
evaluated via the Micoc and a speed is determined. The reel is
operated by a stepper motor whose step-by-step motion (possibly in
full-step mode) is transmitted to the shaft and the reel in a
vibration-damped manner by means of a double-loop coupling. The
ascencion is realized via a freerun. To guarantee safe line
guidance, a raised landing frame is used on the drone, as well as an
eyelet near the ground. Microcontroller and motor are powered by
separate batteries.
Alternative solution AS3:
The travel measurement obtained by means of
a potentiometer is evaluated via the Micoc and a speed is
determined. The reel is operated by a stepper motor whose movement
is transmitted to the shaft and the reel by a belt and two pinions.
The ascencion is realized by a freerun, and for the landing, a
raised platform is used to guarantee the safe line guidance. The
microcontroller and motor are powered by separate batteries.
