Description

technical field [0001] The invention relates to the technical field of underground communication in coal mines, in particular to a mining mobile device communication system based on an optical fiber automatic retractable device. Background technique [0002] With the advancement of science and technology, the degree of mechanization and automation of coal mines continues to increase, and the status of communication technology in coal mine production is becoming more and more important. necessary means. Coal mine communication system is developing towards a comprehensive information network integrating video, image and data transmission "three in one". However, due to the constraints of communication equipment technology and special environmental conditions, underground communication in coal mines still has many problems. Due to the poor underground environment, severe humidity and dust, and metal components such as railways, pipes, brackets, and cables are arranged in the ...

AI Technical Summary

Problems solved by technology

Because mining mobile equipment needs to meet the necessary explosion-proof requirements, its mass is too large, and long-distance optical fibers also have considerable weight. Especially small mining mobile equipment, it is difficult to have enough power to drag the optical fiber

Even if the mining mobile equipment has enough power to pull the optical fiber, during the pulling process, the optical fiber will bear a huge pulling force and the friction generated by contact with the ground, which will easily cause fiber breakage and damage, affecting the normal communication of the equipment

The general optical fiber release device can only release the optical fiber autonomously, and the optical fiber needs to be recovered artificially, which not only wastes manpower, but also when the mining mobile equipment is backed up, if the optical fiber cannot be manually lifted or recovered in time, the mining mobile equipment is easy to crush on fiber optics, causing fiber optic damage
