Coal inventory system and data collection apparatus

The invention discloses a coal inventory data collection apparatus comprising an unmanned aerial vehicle, a position collection device, a scanner and a processing unit. To be specific, the unmanned aerial vehicle is used for traversing a dump above the dump according to a preset track; the position collection device arranged on the unmanned aerial vehicle is used for collecting real-time position data of the unmanned aerial vehicle; the scanner arranged on the unmanned aerial vehicle is used for collecting real-time height information between the unmanned aerial vehicle and the dump below; and the processing unit arranged on the unmanned aerial vehicle is used for controlling the unmanned aerial vehicle to fly according to the preset track, obtaining a real-time position coordinate of the unmanned aerial vehicle based on the real-time position data, and obtaining a real-time coordinate of the dump according to the real-time position coordinate and the real-time height. According to the coal inventory data collection apparatus provided by the application, occupation of a bucket-wheel stacker reclaimer can be avoided. During coal inventory each time, a re-installation phenomenon can be avoided; the apparatus can be used directly. Moreover, the operation is simple, the coal inventory efficiency and precision are high. In addition, the invention also discloses a coal inventory system.
