A WIRELESS SURVEILLANCE AND SAFETY SYSTEM FOR MINE WORKS BASED ON ZIGBEE

 

ABSTRACT

 

                       This paper is concerned with the implementation of ZigBee based wireless sensor networks, which has been applied in our service successfully.Wireless Network (WN) used under the coalmine tunnel is an emerging area of research that promises to provide reliable and flexible communication. This paper first discussed the best working frequency about the WN in coalmine. Then, according to the actual circumstances of coal mine, the network structure should adopt cluster-tree topology. We  develop a communication wireless system using ZigBee technology, which can achieve the functions of gas monitoring, wireless communication, personnel management and wireless surveillance, etc. Practical applications showed that the multifunction communication system can satisfy the need of dispatch communication and safety monitor in the coal mine tunnel.

 

              

 

                              This paper addresses a cost-effective,flexible solution of underground mine worker’s 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 propose 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.
