Since the signal detection unit generated signal
is similar to a sinusoidal signal which is divided into vertically
symmetrical positive and negative half-cycles, by
setting the thresholds of the two sets of comparators to
different values, it can be inferred that a waveform of the
signal detection unit generated signal is positive-then-negative
if a positive half-cycle value is detected first,
and negative-then-positive if a negative half-cycle value
is detected first. Further, according to a circuit setting of
the detection circuit, the MCU, through processing, determines
where the self-propelled equipment is located,
i.e. whether the self-propelled equipment is within its
working range delimited by the wire. Then, the control
unit controls a driving apparatus to act accordingly. The
use of the two sets of comparators can reduce the signal
processing burden of the MCU and enhance the efficiency
of the control system.
