SCADA System for Detection of Explosive Atmospheres in Underground Coal Mines Through Wireless Sensor Network

This paper presents a wireless detection system for explosive atmospheres in underground coal mines based on the following methods: triangle Coward and diagram Bureau of Mines, as an alternative solution to the problem that exist in the highly explosive atmospheres in mines. Mathematical analysis and the measurement of the concentrations of the combustion gases in the atmosphere is performed by wireless data adquisition system based on ZigBee, and treated by a programming environment LabVIEW through a SCADA module.

Integration in wireless sensor networks (WSN) IEEE 802.15.4–802.11 for industrial automation

Mining activity is considered the most dangerous job in the world, due to the significant number of human life losses, therefore to mitigate the negative impact of accidents caused by the concentration of explosive atmospheres (ATEX). It is proposed the integration of wireless networks, Wi-Fi and ZigBee, with embedded systems, for the detection of combustible gases in underground coal mines. In addition, the embedded systems have different communication protocols, which share information acquired quickly and intelligently, using devices based on wireless technologies, allowing obtaining great scalability, flexibility and reliability in the handling of the information.
