Embodiment approach 1

[0037] Such as figure 1 As shown, the online monitoring system for mining belt operation based on machine vision is mainly composed of industrial CCD sensor 1, laser line light source 2, dust removal device 3, optical fiber converter 4, optical fiber 5, host computer 6, video acquisition card 7, monitoring Software 8, database 9, sound and light alarm device 10 and bracket 11. Dust removal device 3 includes tempered glass roller and wiper. Industrial CCD sensor 1 and laser line light source 2 are installed in the tempered glass roller. According to the tape width of 1.2 meters, select Two industrial CCD sensors are installed side by side in the tempered glass drum, and the dust removal device 3 including the industrial CCD sensor 1 and the laser line light source 2 is installed on the large frame under the mining tape through the bracket 11. The width of the bracket 11 is adjustable. The maximum 180cm telescopic rod is used to install the dust removal device 3 containing the i...

Embodiment approach 2

[0054] The dedusting device 3 that will contain industrial CCD sensor 1, laser line light source 2 is installed on the plane with the 40cm screw rod by support 11 on the mining tape frame that is 45cm away from the mining tape lower surface. Others are the same as Embodiment 1.

Embodiment approach 3

[0056] With the 40cm screw rod, the dedusting device 3 containing the industrial CCD sensor 1 and the laser line light source 2 is installed on the mining tape frame that is positioned at a distance of 55 cm from the lower surface of the mining tape by the support 11. Others are the same as Embodiment 1.

Abstract

The invention discloses an on-line monitoring system for the mining adhesive tape operation condition based on machine vision, and belongs to the technical field of coal mining equipment on-line testing. The system is characterized in that an industrial CCD sensor is adopted to be matched with a laser line source to collect feature information of a mining adhesive tape image, the feature information of the mining adhesive tape image is positioned by a non-contact speed sensor, data of tine features in the dark is amplified by the laser line source through the effect of brightness contrast, and the feature information of abnormal points on the mining adhesive tape are effectively, accurately and quickly captured and analyzed, so that the longitudinal tearing, scratching, abrasion, deviation and the like of the mining adhesive tape can be subjected to on-line monitoring.

Description

technical field [0001] The invention provides a machine vision-based online monitoring system for the operating condition of mining belts, belonging to the technical field of online testing of coal mine equipment. It relates to a technical scheme of a machine test method for an online test system based on a CCD industrial camera, a light source, and an audible and visual alarm device. Background technique [0002] The mining belt conveyor system is the lifeblood of coal production, and it is a necessary and expensive large-scale system for coal mine production. Mining tape has strong transportation capacity and high carrying power, and is the most economical means of transporting large quantities of materials. Due to long-term high-load operation and some accidental reasons, accidents such as longitudinal tearing of mining belts and running deviations have occurred from time to time, resulting in coal spilling and blocking passages, scrapping of transport belts, damage to l...
