The utility model relates to the technical field of hoisting machinery, and provides a
digital master controller which comprises an operating lever, a
crankshaft, a base frame, a combined gear, a
bevel gear, a sector, a straight gear, a vertical change-over switch mechanism and a horizontal change-over switch mechanism, a gear sector is fixed on the
crankshaft; the gear sector is meshed with a straight
tooth part in the combined gear; a bevel
tooth part in the combined gear is meshed with the
bevel gear; the
bevel gear is connected with the vertical change-over switch mechanism; the gear sector is meshed with a straight gear, and the straight gear is connected with a horizontal change-over switch mechanism; the vertical change-over switch mechanism and the horizontal change-over switch mechanism respectively comprise a
ratchet wheel, a rotating shaft, a contact head, a
cam block and an
encoder; a
ratchet wheel and a plurality of
cam blocks are mounted on the rotating shaft; a contact head is arranged on the
cam block; and the
tail end of the rotating shaft is connected with an
encoder. According to the utility model, the
encoder is arranged to accurately control the operation state of the driving equipment, so that the controller has higher response speed.
