A Wireless Surveillance and Safety System for Mine Workers based on Zigbee

Abstract: This paper addresses a cost-effective, flexible solution
of underground mine workers’ safety. A module of MEMS
based sensors are used for underground environment
monitoring and automating progression of measurement data
through digital wireless communication technique is proposed
with high accuracy, smooth control and reliability. A
microcontroller is used for collecting data and making
decision, based on which the mine worker is informed through
alarm as well as voice system. The voice system with both
microphone and speaker, transforms into digital signal and
effectively communicate wirelessly with the ground control
centre computer. ZigBee, based on IEEE 802.15.4 standard is
used for this short distance transmission between the hardware
fitted with the mine worker and the ground control centre.
