Belt material measuring system based on laser ranging

Abstract

The invention discloses a belt material measuring system based on laser ranging, and belongs to a non-contact belt scale system. The system scans the surface of material through laser scanning ranging equipment and obtains the distance value between a laser head and the surface of the material, cross-section shape and area of the material are obtained through the distance value, and combining real-time running speed of a belt obtained by belt speed measurement equipment, instant volume and weight of the material transported on the belt are obtained. The adoption of centralized type data processing method, accurate measurement and monitoring for multiple belts can be achieved at the same time. Equipment and original parts of the system are much less. The belt material measuring system based on laser ranging has the advantages of simple structure, high measurement accuracy, safe and reliable operation, low implementation cost and convenient application and popularization in various industries with the application of travelling belts.

Description

Technical field [0001] The invention relates to a belt material measurement system based on laser ranging, which relates to the fields of laser ranging and communication. Background technique [0002] Conveyor belts are important equipment for short-distance transportation of materials and are widely used in mining, agriculture, food, tobacco and other production industries. Accurately measuring the quality of belt conveyed materials has positive and important significance for automatic production control, output statistics, and control of production costs. At present, the belt measurement in actual production mainly uses electronic belt scale and nuclear belt scale. The electronic belt scale uses a pressure sensor to measure the pressure of the belt on the sensor caused by the weight of the material, so as to realize the measurement of the weight of the material. The electronic belt scale adopts contact measurement, and the mechanical structure is complicated, including roller...

AI Technical Summary

Problems solved by technology

The nuclear belt scale adopts non-contact measurement, which overcomes some shortcomings of the electronic belt scale, but there are still problems such as low precision, radioactive source safety management, and complicated calibration.

At present, there are still some methods for measuring belt materials based on the principle of image processing, but due to reasons of accuracy and practicability, most of them are in the theoretical stage and have not yet formed products.
