Belt conveyor muck volume flow real-time detection method and system

Abstract

The invention discloses a belt conveyor muck volume flow real-time detection method and system. The detection method comprises the steps of: emitting line laser to a belt in a no-load state, and obtaining a first contour intersection line of the line laser and the belt and a first area defined by the first contour intersection line and the belt; emitting line laser to the belt under the state that the belt is provided with muck, and obtaining a second contour intersection line of the line laser and the belt and a second area defined by the second contour intersection line and the belt through the visual technology; and obtaining the moving speed of the belt, and obtaining the deslagging flow of the belt according to the first area, the second area and the moving speed. According to the method, the detection precision of the deslagging flow of the belt can be improved, rapid and accurate operation is achieved through visual nondestructive detection, the detection timeliness can be improved, and inconvenience caused by traditional contact type belt flow volume measurement to material conveying and loss of detection equipment are avoided.

Description

technical field [0001] The invention relates to the technical field of belt conveyor design, and more specifically relates to a real-time detection method and detection system for the volume flow rate of muck in a belt conveyor. Background technique [0002] With the continuous improvement of the requirements for the intelligent development of underground engineering equipment, it is necessary to monitor the working status of the equipment during the construction of underground equipment. The slag volume and flow rate of the belt conveyor are one of the important indicators reflecting the equipment operation status information during the shield tunneling process, and a set of targeted and effective equipment is required for detection. [0003] At present, during the construction process, the detection methods for the slag discharge volume of the belt conveyor include estimation based on the belt speed, rough estimation based on the transport hopper, etc., or setting a scrape...
