Abstract:
1. A control system for a machine for digging or drilling earth, said machine for digging or drilling earth comprising: a digging head arranged to dig ground; a flexible load-bearing cable arranged to support said digging head during operation; and a first winch comprising a first drum about which at least part of the flexible load-bearing cable is wound, and a first motor arranged to actuate, in rotation, said first drum; a second winch comprising a second drum about which at least part of the flexible load-bearing cable is wound and a second motor arranged to actuate, in rotation, said second drum; an electronic control unit adapted for controlling the movement of the first winch and the second winch; a velocity sensor device arranged in each branch of the flexible load-bearing cable coming out from each of the first winch and the second winch and adapted for monitoring the movement of said flexible load-bearing cable; said electronic control unit being arranged to calculate the differential velocity with which the digging head can move, based on the detections of the velocity sensor device.
