IoT RELAY WIRELESS REPEATER FOR WIRELESS DATA TRANSMISSION AND RECEPTION IN UNDERGROUND MINES AND CLOSED AREAS

摘要

An IoT relay wireless repeater used for smart ventilation systems in underground mines and closed areas using IoT technology is disclosed. Each of these is mounted on a mobile body and can be wirelessly connected to a terminal within a communication range among a plurality of IoT sensor network terminals while moving in the gang, and sensing data is received from each connected IoT sensor network terminal. The IoT relay wireless repeater transfers the received data to one or more gateway repeaters.
