[0023] Working principle of walking monitoring device:

[0024] When the bucket wheel machine needs to move forward or backward, the travel drive device starts, the drive shaft rotates, and drives the shaft of the travel detection device to rotate synchronously, and then transmits the torque to the encoder through the coupling, finally realizing the synchronous rotation of the encoder and the drive shaft. The encoder calculates the forward or backward distance of the bucket wheel machine by the number of rotations of the drive shaft, and then obtains the travel distance and position of the bucket wheel machine.
