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

摘要

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.
