Coal Field The Size Of The Heap Of Coal Automatic Measurement Mapping System

Measuring the amount of stored coal in the firepower plants is one of the most important parts of production and management of the plants, but no production for such use is available at present. Thus this paper mainly works on the subject called "the automatic measuring system for the volume of coal heaps in the firepower " which is used to make it possible for firepower plants to use and manage coal scientifically.The angle-servo scanning system loaded range finder using laser is applied in this measuring system, which can meet the need of easuring the account of stored coal. The system also has functions of collecting and processing data , printing metering forms and drawing three -dimensional pictures or profiles of the coal heaps.In the paper, the author first analyses the designing idea, components of hardware, working principal, and fulfillment of the functions. Then, using Delphi as programming language to analyses, process and calculate the data, the author introduces how to realize the system software; Finally, the accuracy of measuring system is analyzed on the base of measurement error and truncation error, which proves theoretically that the accuracy of the system is satisfactory.
