Laser ranging dynamic detection belt deviation system

Abstract

The invention discloses a laser range-measuring type dynamic belt deviation detection system, which includes a belt conveyor, a laser scanner, a serial port processor, a speed sensor, a single-chip computer, and a host computer; the laser scanner is fixedly installed on the side of the edge of the transport belt side, the installation distance meets the error range of the belt deviation, and the scanning surface of the laser scanning distance measuring device is perpendicular to the horizontal plane of the belt and the ground; the laser scanning data is sent to the Ethernet by the serial port processor for remote transmission; the speed sensor is fixed on the belt The conveyor is on the central axis of the idler roller and rotates coaxially with the idler roller; the belt speed data is collected by the single chip microcomputer and transmitted to the remote host computer through the GSM / GPRS module; the host computer calculates in real time according to the measurement data of the detection system. The invention can dynamically detect the deviation of the belt, facilitates the discovery of the initial position of the deviation of the belt, has simple system structure, high degree of automation, strong real-time performance, and is not affected by the external environment on the determination of material distribution.

Description

technical field [0001] The invention relates to a laser ranging type belt deviation detection system, which belongs to the technical fields of laser ranging and communication. Background technique [0002] Belt conveyor is an important equipment for short-distance transportation of materials, and is widely used in mining, agriculture, food, tobacco and other production industries. The conveyor belt is the key equipment of the conveying system, and its safe and stable operation directly affects the production operation. The deviation of the conveyor belt is the most common failure of the belt conveyor, and its timely and accurate treatment is the guarantee of its safe and stable operation. However, during the operation of the belt conveyor, the deviation of the conveyor belt often occurs, causing material spillage or belt edge wear, which will directly affect the service life of the conveyor belt, and even lead to the shutdown of the coal transportation line, affecting safe ...

AI Technical Summary

Problems solved by technology

The deviation detection switch is a mechanical switch, which adopts a contact detection method. When it is used in a relatively harsh production environment such as a coal mine, it is easily affected by coal dust, mud, oil sludge, etc., and it is prone to false alarms and missed alarms. Waiting for failure

Therefore, the deviation rate of the deviation detection switch is high, the degree of automation is low, and the production efficiency is low

In addition, based on laser detection of conveyor belt deviation, the method of detection is that the laser is fixed. This detection method cannot implement dynamic detection of conveyor belt deviation, and cannot detect local deviation of the conveyor belt.
