In this paper, the computer vision(structured linght) is applied to the automation and control system of the bucket wheel stacker and reclaimer. When the bucket wheel stacker and reclaimer is starting or working, it can find the coal and stack or reclaim automatically. This paper emphasizes on the research on the structure and principle of the automation and control system of the bucket wheel stacker and reclaimer. I have a test of the structured light, the result is satisfaction.The communication way between the bucket wheel stacker and reclaimer and the central control room is studied. Comparing many ways, i use the power line carrier communication. solving the hard nut which the bucket wheel stacker and reclaimer working have not bring into the whole automatically controlling system of transporting coal for long time. Comparing with the former artificial operation, it increases the work efficiency and reduces ineluctable waste of resources because of the artificial factor ,and availably makes use of the current resources.
