Real-time coal flow monitoring is crucial for efficient mine transportation. Traditional vision acquisition devices generate two-dimensional images that are not accurately identified in the complex underground environment, such as dust, water mist, and low light. In this paper, we propose a conveyor belt detection method integrates laser scanning binocular to address problem. Our proposed has several advantages over traditional approaches. Firstly, calibrate camera using Zhang's calibration...

In the actual production of coal mines, transmission needs existing underground applications cannot be met due to a lack strategies and customized equipment for 5G application scenarios, which causes increased data processing delay low efficiency. To solve problem above, mobile edge computing (MEC) technology based on wireless base station is studied, communication capabilities improved by caching dynamic resource allocation according situation mines. The experimental result shows that under...

Moiré superlattices formed by graphene-covered Ru(0001) are known as excellent templates for the synthesis of monodispersed transition metal nanoclusters, but an accurate description structural evolution at atomic level is still lacking. Herein, using first-principles calculations, we systematically explore nucleation and growth Pt nanoclusters (PtNCs) on such moiré superlattices. Our calculations reveal that, PtNCs, FCC regions preferred compared with other due to stronger C-sp3...

In traditional conveyor belt edge detection methods, contact methods have a high cost. At the same time noncontact low precision, and based on convolutional neural network are limited by local operation features of convolution itself, causing problems such as insufficient perception long-distance global information. order to solve above problems, dual flow transformer (DFTNet) integrating information is proposed for detection. DFTNet could improve accuracy suppress interference image noise....

The Mine Internet of Things (MIoT), as a key technology for reconstructing post-disaster communication networks, enables user to monitor and control the safety an affected roadway. However, due challenging underground mine environment, MIoT suffers from severe signal attenuation, vulnerable nodes, limited energy, which result in low level network reliability MIoT. To improve transmission reduce energy consumption, directional-area-forwarding-based energy-efficient opportunistic routing...
