To solve the problems occur in coal yard management

such as bad real time capabilities

low precision

and low efficient management of coal-yard volume

a novel multifunctional control system is designed in this paper. Based on the LiDAR technology

this system can scan the coal in the yard automatically to obtain field point cloud data and reconstruct three dimensional model through Delaunay algorithm according to the field point cloud data. Then

it calculates the coal volume automatically. Meanwhile

according to all the point-cloud data

it determines the strategy of stocking and reclaiming

and can control the machine to work following the orders. The proposed system can meet the demand of fuel management in coal yard and achieve the purpose of reducing cost and increasing efficiency.
