The depth measurement method is to obtain the vacancy depth in the silo by manually dropping the plumb bob to the surface of the material pile in the silo, and then calculate the volume of the material pile in the silo. Due to the uneven upper surface of the material pile in the silo, the measurement data has low accuracy, large error and other problems, and the measurement results are only for reference, and cannot be used as internal statistical data.

3D laser scanning technology is a new means of data acquisition, which has the characteristics of initiative, high precision, rapidity, etc. It uses the principle of laser ranging to quickly reconstruct the line, surface, volume and other omnidirectional 3D models of the measured object by recording the 3D coordinates and texture information of a large number of dense point clouds on the surface of the measured object. Its application in silo capacity measurement can improve the traditional problems of long measurement time, high work intensity and low accuracy.

As a storage and measuring instrument, the accuracy of silo capacity measurement directly affects the economic interests of enterprises. In this project, three-dimensional Mipo Company uses A100 three-dimensional laser scanner to collect data from the silo.

When measuring the silo capacity, invert the 3D scanner through a special installation device and fix it at the silo metering port to ensure that the 3D laser scanning equipment extends into the proper position of the silo port, and level the installation device. Set the parameters of the control system such as speed and rotation angle outside the silo. The rotation speed and angle will be horizontally rotated by 0 ° - 180 ° according to the set parameters, so as to scan the surface of the material pile in the silo into a three-dimensional point cloud surface. The three-dimensional laser scanning technology can not only realize the rapid and accurate measurement of the silo, but also use the obtained spatial point cloud data to quickly establish the surface model of the tanker, providing reference data for the detection of the ash level of the silo internal surface area and other applications

In the field of power plants, steel plants and coal mines, there is often a demand for coiled materials in silos or sheds. Due to the large volume and irregular shape, it is difficult to measure.

This 3D laser scanner is a good solution to this problem. The scanner has a range of up to 100 meters. It is driven by a horizontal 360 degree rotary motor. Due to the friction braking technology and high-precision angle encoder, the equipment can rotate and scan manually and automatically. The scanning speed is fast. It only takes a few minutes to scan once. Due to the good real-time performance of the coal handling system, the automation management level of the power plant can be greatly improved, saving manpower and creating benefits.

This product can not only realize the coal yard scanning of a single instrument, but also can connect multiple laser scanners via LAN or wireless network, and automatically set the scanning frequency through the control center software without manual intervention. After scanning, the computer synthesizes and processes the data obtained by the three-dimensional laser scanner, uses the digital fitting technology to establish the digital model of the coal yard surface, calculates the volume of the coal pile according to the volume fraction principle, and draws the three-dimensional graphics of the coal yard according to the digital model. The calculated volume number multiplied by the specific gravity of coal is the coal storage in the coal yard.
