The invention relates to the field of
coal yard management, in particular to a digital
coal yard automatic
data acquisition system which comprises a bucket wheel
machine attitude acquisition module, a bucket wheel
machine position acquisition module, a
granularity data acquisition module, a
data transmission module, a digital map module and an
inventory analysis module. The bucket wheel
machine attitude acquisition module is used for acquiring bucket wheel machine attitude information in real time, and the information comprises
cantilever rotation angle and pitching angle information and synchronous
coal unloading belt weigher flow data, records the stacking position and quantity, and transmits the recorded data to the
data transmission module. According to the invention, the data in the coal
yard is collected in real time, and the data collected in real time is presented in real time through the three-dimensional map, so that workers can visually understand the equipment working parameters and the coal quantity
inventory data in the coal yard, accurately carry out inventory checking, analyze the inventory change trend and formulate a reasonable purchase plan and a reasonable sales strategy; the situation of inaccurate data caused by human errors is avoided, and the
management efficiency is improved.
