Problems solved by technology

Although positioning and straightening alone can achieve the purpose of positioning under normal circumstances, in special cases, such as problems in the connection between the scraper conveyor and the hydraulic support, it is difficult to accurately judge the relative positional relationship of each equipment
Once the above situation occurs, there may be major safety problems, which will affect the normal production of the working face and even endanger personal safety.

Embodiment Construction

[0018] See attached figure 1 , which describes a preferred embodiment of the system for executing the image measurement-based working face equipment positioning method according to the present invention. The working face equipment positioning system based on image measurement is used for positioning control of working face equipment, wherein the working face equipment mainly includes coal shearers, hydraulic support groups and scraper conveyors, and of course may also include other equipment. The working surface hydraulic support group consists of a plurality of hydraulic supports. In this embodiment, the number of hydraulic supports is 6, and a video camera is arranged on the hydraulic support. The conveyor is composed of multiple chutes, each of which is pasted with identification tapes, and each identification tape forms the first video identification belt, the second video identification belt is set on the ground in front of the hydraulic support group, and the third video...

Abstract

The invention relates to a working face equipment positioning method based on image measurement, which comprises the following steps: arranging a camera on a hydraulic support, arranging a first video identification zone on a scraper plate transporter, arranging a second video identification zone at the front of a hydraulic support set, arranging a third video identification zone on a coal cutter, connecting the camera with a working face electro-hydraulic control system; performing real-time monitoring on the first video identification zone, the second video identification zone and the third video identification zone by the camera, transmitting the monitored image to the working face electro-hydraulic control system; determining and analyzing the relative position relation of the first video identification zone, the second video identification zone and the third video identification zone in the monitoring image by the working face electro-hydraulic control system, and then regulating the working face equipment. According to the invention, the positioning is rapid and accurate, the precision is high, the influence due to environment is little, the motion adjustment is directly carried out according to the equipment position, what you see is what you get, the intermediate link is less, and the unfavorable influence of data transmission error to positioning by a traditional sensor employment mode is avoided.

Description

technical field [0001] The invention relates to a positioning method for working face equipment, in particular to a comprehensive positioning method for positioning working face equipment with image measurement. Background technique [0002] The fully mechanized mining face is composed of shearer, scraper conveyor and hydraulic support. The scraper conveyor is composed of butt joint chute sections. The sub-fixed connection, through the telescopic action of the hydraulic support to push the jack, promotes the migration of the scraper conveyor, and the coal shearer moves along the scraper conveyor to cut the coal seam. In actual production, according to the requirements of the regulations, the shearer, the scraper conveyor and the hydraulic support must reach a certain positional relationship, that is, the positioning of the three machines. [0003] At present, the existing positioning systems are only positioning and straightening systems for scraper conveyors or hydraulic s...
