Allocation Strategy for Wireless Communication Channel of Coal Mine Underground
This paper proposes an improved wireless communication channel reservation policy to address the impact on network performance cannot be analyzed under the original model with the primary and secondary users communication channel occupancy rates, and the problem that the secondary user blocking state is significantly higher than the primary user blocking probability under the original model. Si...
متن کاملA Search-and-Rescue Robot System for Remotely Sensing the Underground Coal Mine Environment
This paper introduces a search-and-rescue robot system used for remote sensing of the underground coal mine environment, which is composed of an operating control unit and two mobile robots with explosion-proof and waterproof function. This robot system is designed to observe and collect information of the coal mine environment through remote control. Thus, this system can be regarded as a mult...
متن کاملsDEVELOPMENT OF COAL MINE SAFETY SYSTEM USING WIRELESS SENSOR NETWORKS
In this work, a system is proposed for safe Coal Mine Monitoring, which plays an important role in coal mine safe production. Wi th continuous enlarging of exploiting areas and extension of depth in coal mine, many laneways become monitoring blind areas, wh ere are lots of hidden dangers. It is very difficult to lay cables which are not reliable and not effective. For to overcome this , a new s...
متن کاملA Review of Mine Rescue Ensembles for Underground Coal Mining in the United States.
The mining industry is among the top ten industries nationwide with high occupational injury and fatality rates, and mine rescue response may be considered one of the most hazardous activities in mining operations. In the aftermath of an underground mine fire, explosion or water inundation, specially equipped and trained teams have been sent underground to fight fires, rescue entrapped miners, ...
متن کاملDesign of an Adaptive Coal Mine Rescue Robot using Wireless Sensor Networks
In early decades, rescue operation in coal mine was treated as a dangerous task. After explosions occur, when rescue workers get into the tunnel without environment conditional awareness, they are facing heavy damages due to consecutive explosions [1]. This bring the necessity to detect the status of the mine environment details such as toxic gases, high temperatures through wireless sensors to...
