英文摘要：

Taking Tanggang raw material stockyard for example, the process flow and control method of large scale raw material stockyard were introduced. The common control modes and implementation methods were described in detail, and the system construction, hardware and software design were also discussed. The technologies of industrial field bus and industrial ethernet have been combined and applied in control system of a large scale comprehensive raw material stockyard, thus the problems concerning data and information transmission control for the complicated system with long distance, strong disturbance and large capacity have been solved.
