Automatic Inventory Of Coal Stacks And Management System

Coal planning is an important work in production managements of power plant as it influences directly the running of the economy of the plant. It is a key problem, and also a difficult problem that puzzles coal plant all the time how to measure the coal inventory automatically and accurately. It is necessary to measure the volume of various calorific coal stacks quickly and accurately in order to gain the inventory of coal stacks, which is a main basis for the plant to do cost accounting, economic benefits evaluation and scientific management.Recent years, with the continuous development of computer hardware, especially the appearance and development of GPU, graphical processing technique based on GPU has been widely used in commercial high-end computing, generation of medical image and land surveying, etc.Aiming at the automatic inventory of coal stacks and management system, research work carried out in the paper can be stated as follows: Data from surface of coal stacks can be gathered, and 3D coordinate data can also be generated by means of the hardware system which is composed of 3D laser range-finders, stroke sensor and step-motor. 3D coordinate data is used to draw 3D images by Visual Studio 2005 Sp1 and DirectX SDK 2009.3. By using 3D image reconstruction algorithm based on GPU, and high-speed capacity of GPU consist of the floating-point operation ability and the geometric operation ability to generate 3D image, through the processing of dispose image by sampling the new 3D model, homogenization, border demarcation, 3D model based on arithmetic of Delaunay'triangulation dividing can be established. With the 3D model, the volume of subsidiary pile can be calculated. Afterward, by adding to the volume of subsidiary pile the total volume can be obtained. The development and design of coal management system by Visual C++6.0 can provide more fast and effective management to the power plant.Research work indicates that instantaneity and accuracy of the system of automatic measuring coal have been improved greatly, and satisfactory results also have been obtained.
