Embodiment

[0048] In this embodiment, an industrial-grade linear array CCD camera and a Gigabit Ethernet network are taken as examples for illustration. The schematic diagram of the conveyor belt online monitoring system is as follows: Figure 9 shown. The number of pixels of the industrial-grade linear array CCD camera can be selected according to actual needs.

[0049] The image information of the conveyor belt is collected in real time by an industrial-grade linear array CCD camera, and the image information of the conveyor belt is transmitted to the computer through the Gigabit Ethernet network, and the computer is used to process the running image of the conveyor belt, thereby realizing the monitoring and monitoring of the running state of the conveyor belt. Troubleshooting. For example: for an industrial-grade linear array CCD camera with 2048 pixels and a working line frequency of 19kHz, when monitoring a conveyor belt running at a speed of 6m / s, it will generate 37.1MB of image ...

Abstract

The invention discloses a conveyor belt online monitoring system based on machine vision, which is used for real-time detection of conveyor belt deviation, surface damage and longitudinal tear faults. Image information; image transmission module, used to transmit the conveyor belt image collected by the image acquisition module to the computer through Ethernet; image processing module, used for real-time processing of the conveyor belt image transmitted to the computer; fault diagnosis and alarm module, used for identification The running state of the conveyor belt, if the deviation, surface damage and longitudinal tear fault are diagnosed, the alarm will be reported in time; the bracket is used to fix the image acquisition module to the appropriate position of the conveyor belt. The monitoring system provided by the present invention can improve the monitoring level of the conveyer belt state, and achieve the purpose of reducing the manpower and increasing the efficiency of the enterprise. The invention also discloses an online monitoring method for the conveyor belt comprising the monitoring system.

Description

technical field [0001] The invention relates to a system and method for on-line monitoring of conveyor belts, in particular to a system and method for on-line monitoring of conveyor belts based on machine vision, and belongs to the field of equipment status monitoring. Background technique [0002] Conveyor belt is an important part of belt conveyor in many industries such as mines, ports, chemical industry, metallurgy, electric power, cement, etc. It has become the second largest rubber industrial product after tires. China is the world's largest producer and consumer of conveyor belts. According to reports, the compound growth rate of China's conveyor belt production in the six years from 2003 to 2008 was more than 20%, and by 2008 it had reached 230 million square meters, accounting for the world's annual conveyor belt. About one-third of the total market size with 600-700 million square meters. [0003] During the working process, the conveyor belt often has failures su...
