Laser ranging type dynamic detection belt deviation system

Abstract

The invention discloses a laser ranging type dynamic belt deviation detection system, which comprises a belt conveyor, a laser scanner, a serial port processor, a speed measurement sensor, a single chip microcomputer and an upper computer, wherein the laser scanner is fixedly installed on the side edge of the edge of a conveying belt, the installation distance meets the error range of belt deviation, the scanning face of laser scanning distance measuring equipment is perpendicular to the horizontal plane of the belt and the ground, the laser scanning data is sent to the Ethernet by the serialport processor to realize remote transmission, the speed measurement sensor is fixed on the central shaft of the ascending carrier roller of the belt conveyor and coaxially rotates with the carrier roller, belt speed data are collected by the single chip microcomputer and transmitted to the remote upper computer through a GSM / GPRS module, and the upper computer carries out real-time calculation according to measurement data of the detection system. According to the invention, belt deviation can be dynamically detected, the initial position of belt deviation can be conveniently found, and the system is simple in structure, high in automation degree and high in real-time performance and is not affected by the external environment on material distribution measurement.

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.
