Problems solved by technology

[0002] In thermal power plants, the belt conveyor is the main equipment for conveying coal. However, during the use of the belt conveyor, due to the unsmooth feeding of the belt conveyor head, the chute of the belt conveyor head will be blocked. If it is not found in time , will cause a large area of ​​silt on the belt machine head, affecting the operation of the entire belt transport device, and in serious cases, it will burn out the belt motor

Abstract

The invention discloses a belt material blockage detection method and system based on laser scanning. The method comprises the following steps of: S1, arranging a first laser scanning device and a second laser scanning device above a belt; S2, establishing a first rectangular plane coordinate system and a second rectangular plane coordinate system by taking the first laser scanning device and the second laser scanning device as original points respectively; S3, intercepting a first cross section and a second cross section of a material on the belt, calculating the volume Vin of the material passing through the first cross section within the time of delta t, and calculating the volume Vout of the material passing through the second cross section within the time of delta t; and S4, presetting an alarm threshold value Vc; and when Vin-Vout is larger than Vc, judging that material blockage occurs on the belt. The invention provides the belt material blockage detection method and system based on laser scanning, and aims to measure the volumes of coal piles entering and exiting from a chute in unit time and sample the distribution condition of the coal piles at the position of the belt so as to judge whether the chute is blocked or not.

Description

technical field [0001] The invention relates to the field of belt blocking detection. More specifically, the present invention relates to a method and system for detecting belt blockage based on laser scanning. Background technique [0002] In thermal power plants, the belt conveyor is the main equipment for conveying coal. However, during the use of the belt conveyor, due to the unsmooth feeding of the belt conveyor head, the chute of the belt conveyor head will be blocked. If it is not found in time , It will cause a large area of ​​silt on the belt machine head, which will affect the operation of the entire belt transport device, and in severe cases, the belt motor will be burned. Therefore, in order to ensure the normal operation of the belt conveyor, it is imperative to detect the occurrence of material blocking in time. Contents of the invention [0003] The object of the present invention is to provide a method and system for detecting material blocking in a belt ...
