The invention belongs to the technical field of
trajectory planning, and provides an electric
shovel unmanned mining method and
system based on digital twinning in order to solve the problem that the design of an electric
shovel unmanned mining trajectory is difficult to deal with a complex heap surface, and the method comprises the following steps: obtaining
sensing data, a historical mining trajectory and historical heap
surface point cloud data; an electric
shovel unmanned mining digital twin
system is constructed based on the
sensing data; uploading the historical mining trajectory and the historical heap
surface point cloud data to a
central database, and training by using generative
artificial intelligence to obtain prediction trajectories suitable for different mine fields; constructing an agent model by using a neural network, calculating to obtain a predicted fullness rate, and performing simulated excavation according to the predicted fullness rate and the predicted trajectory to obtain electric shovel excavation
control data; according to the method, deep
reinforcement learning is utilized, the electric shovel unmanned excavation track is generated based on the electric shovel excavation
control data, the electric shovel is controlled to conduct unmanned excavation in real time, the safety of the excavation process is guaranteed, and the track control precision of the electric shovel is also improved.
