Excavator roller control system and control method

The invention relates to the field of engineering machinery, in particular to an excavator roller control system which comprises a roller used for winding and unwinding a cable; the roller motor controller is used for controlling the roller to operate; the whole vehicle controller is used for controlling the forward and reverse rotation of the roller; the electric control handle is used for operating and monitoring the working state of the operating rod; the control method based on the excavator roller control system comprises the following steps that (1) the vehicle control unit calculates the walking speed of the excavator through the rotating speed of the motor; (2) the whole vehicle controller sends the walking speed of the excavator to a roller motor controller; 3, the roller motor controller controls the running speed of the roller according to the walking speed of the excavator, so that the take-up and pay-off speed of the cable is matched with the walking speed of the excavator.
