Zig-Bee Based Intelligent overcoat for Coal Miners

Abstract

This project designs a monitoring and protection system for underground workers based on the wireless network of zigbee. This project addresses an economical, supple, portable continuous monitoring of underground parameter such as high pressure without air gap, collapsing of an atom, chemical reaction of molecules, dirty life cycle, waste management(chemical, nuclear and alcohol factories etc..,) under the earth makes toxic amount of minerals causing toxic gases(CO,SO2,H2S,NH3,CH4,NOXIOUS etc.,) are detected by gas sensor(MQ135,MQ7 etc., as per the requirement of noxious etc.,) and automating sequence of measuring data using microcontroller and transmit information through digital wireless communication system(zigbee network) to controller. By converting the zigbee protocol to the Ethernet protocol, the controller receives data and sends them information via LCD (PC) with the concept of M2M (Machine to machine - controller room, machine to mobile fire service, mobile to mobile workers and public). The abnormal situation can be projected with high precision, soft controller, reliability, less compatability, less power and large span of battery.
