The utility model discloses a three-wire
mooring cable for an unmanned aerial vehicle, which comprises an
anode high-
voltage cable, a
cathode high-
voltage cable, a low-
voltage cable and a
signal transmission module, and is characterized in that one end of the
anode high-voltage cable, one end of the
cathode high-voltage cable and one end of the low-voltage cable are all connected to the ground end; the other end of the positive high-voltage cable, the other end of the negative high-voltage cable and the other end of the low-voltage cable are all connected to the
sky end, the low-voltage cable is further connected with the
signal transmission module, the positive high-voltage cable and the negative high-voltage cable are used for transmitting high-voltage power, the low-voltage cable is used for transmitting low-voltage signals, and the
signal transmission module is connected with the signal transmission module. The signal transmission module includes a plurality of discrete components. According to the utility model, a wired cable is adopted for transmission, external
wireless interference signals can be well resisted, the application of chips in the signal transmission module is reduced, a plurality of discrete components are adopted, the circuit board can be simplified, the
failure rate can be reduced, the computing power can be reduced, and the signal transmission module can be widely applied to the technical field of signal transmission.
