In view of the universal problems that the material management of the biomass power plants is loose, and they lack standardization and real-time interaction, this paper proposes a system based on the method of intensive management to control the whole process of power plant material. By analyzing the whole process of power plant material management and applying the Internet of Things, the method can simplify the management process. By making use of the resources to maximize and data mining, material utilization, the circulation rate and quality control management can be improved. This system has been applied in Shandong Gaotang power plant, which raised the level of materials management and economic effectiveness greatly. It is of great significance for safe, cost-effective and highly efficient operation of the plant.
