An Emergency Communication Architecture Based on Ethernet and WSN for Coal Mines

摘要

Underground coal mines are very necessary to adopt a flexible, adaptable, and reliable network communication technology to guarantee data transmission to be successful. This paper attempts to propose an emergency communication architecture based on Ethernet and WSNs to repair the cable network happening fault or be destroyed during mine disaster. By means of activating wireless sensor nodes around breakpoints of the cable network, a logic network bridge can be dynamically formed for ensuring the emergency communication to be valid.
