The invention belongs to the technical field of bucket wheel
machine control, and discloses an unattended
automatic control system of a bucket wheel
machine, which is characterized in that a three-
dimensional modeling technology is utilized to respectively construct geometric models of a
coal yard, a bucket wheel
machine and a material
pile, and the geometric models are combined to generate a dynamic
coal yard model; positioning information of the bucket wheel machine is obtained through the
wireless positioning technology, and an automatic moving path of the bucket wheel machine is generated in combination with the dynamic
coal yard model and the material taking
work plan and sent to a bucket wheel controller to control the moving state of the bucket wheel machine; the safety stability between the bucket wheel machine and the material
pile in the material taking process is evaluated according to the automatic moving path of the bucket wheel machine and the
microwave measurement technology, and a limit protection device is driven based on the
evaluation result to conduct protection operation on the material
pile; and judging the accuracy of the automatic moving path of the bucket wheel machine according to a material taking result, and analyzing the feasibility of bucket wheel machine
automatic control based on an accuracy result to determine an
automatic control strategy of the bucket wheel machine. According to the invention, the requirements on operators are greatly reduced, and the labor cost is reduced.
