Problems solved by technology
The measurable area of laser scanning is limited, and the measurement accuracy is affected by the installation position. If it is too high, the laser intensity will attenuate, and if it is too low, it will not be possible to obtain the 3D point cloud information of the real coal surface.

The invention relates to a coal flow velocity and coal flow measuring system and a measuring method thereof. The coal flow speed and coal flow measurement system is provided with a depth measurement module, a looped network access module and a data service module, the depth measurement module transmits signals to the looped network access module, and the looped network access module transmits signals to the data service module; and the depth measuring module is mounted above the conveyor. The measurement method comprises the following steps: collecting and uploading a coal flow point cloud picture, obtaining the point cloud picture for feature matching, and calculating the coal flow speed and the coal flow rate. The measuring system is simple in structure, the depth measuring module can measure the coal flow speed and the coal flow at the same time, and installation, use and maintenance are very convenient; the measuring method is easy and convenient to operate, the measuring error of the coal flow speed and the coal flow rate is small, and the measuring accuracy is high.
Description
technical field [0001] The invention relates to the technical field of coal measurement, in particular to a coal flow velocity and coal flow measurement system and a measurement method thereof. Background technique [0002] With the proposal of the concept of building smart mines, my country's coal industry is developing from extensive production in the past to saving and intelligent. As an important transportation tool in the coal production process, the belt conveyor runs at full speed for a long time in the actual production process, and does not realize the speed regulation according to the load, resulting in a lot of unnecessary cost consumption. In order to realize intelligent control such as automatic speed regulation of belt conveyors and early warning of blockage of closed transfer points, it is necessary to detect the speed and coal flow of belt conveyors in real time. [0003] The speed measurement of mining belt conveyors usually adopts speed sensors (rollers ar...
