Cable type sensor for pose monitoring of coal mining machinery

Abstract

The invention relates to a pose monitoring control system for coal mining machinery of a fully mechanized coal mining face, and discloses a cable type sensor for pose monitoring of coal mining machinery. The cable type sensor comprises a carrier in the form of a cable and a plurality of optical fibers fixed on the carrier, the optical fibers are arranged parallel to the axial direction of the carrier, and at least two optical fibers are located on the same vertical plane and / or at least two optical fibers are located on the same horizontal plane. During use, all parts within the full-length range of the sensor are fixedly mounted relative to a rail on which the coal mining machine runs; when the rail deforms at a certain position, the optical fibers in the inner arc are extruded, the optical fibers in the outer arc are stretched, so that the scattering spectral line of the laser is changed, the bending angle is calculated through change of the scattering spectral line, and the offset is finally calculated. Online real-time monitoring on the three-dimensional pose and moving track of the coal mining machine, the straightness of the working surface and the like is realized, the structure is simplified, the processing cost is reduced, and the processing efficiency is improved.

Description

technical field [0001] The present invention relates to a coal mining machine attitude monitoring and control system in a fully mechanized mining face, in particular to a cable-type sensor for online real-time monitoring of the coal mining machine's three-dimensional attitude, running track, straightness of the working face, etc. . Background technique [0002] Coal mines are my country's main energy consumption and raw materials. my country's coal mines are rich in resources. In the current and future period, coal mines will always occupy the main energy position in our country. With the development of coal mine automation and intelligent technology, the fully mechanized mining face has basically realized the automatic production mode of the working face equipment, which is mainly based on the memory cutting of coal shearers and automatically controlled by hydraulic supports and machines. In this production mode, the automatic control of the straightness of the working fac...

Problems solved by technology

When in use, all places within the full length of the cable sensor are fixedly installed relative to the track on which the shearer runs, that is, all parts of the full length of the cable sensor and the track cannot move relative to each other. The cable sensor disclosed in the above patent application The sensor can be used to monitor the deformation at any position on the track, but in this structure, each group of distributed optical fiber sensors is arranged in a spiral shape. On the one hand, the form is relatively simple and the structure is relatively complicated. On the other hand, the spirally arranged optical fiber sensors The processing technology when connecting with the carrier is time-consuming and laborious, so the production efficiency is relatively low
