OVERVIEW:
DESIGN OF MONITORING SYSTEM FOR COAL MINES SAFETY BASED ON WIRELESS SENSOR NETWORKS
By P. RaviKiran
Roll No:08621D5506


OVERVIEW:
The main objective is to get the Environmental characteristics like temperature, humidity and methane gas of underground coal mines and send the information to surface using ZIGBEE wireless sensor nodes and also get employee info using RFID module.

Current Scenario:
The foremost critical task for coal mines is of keep tracking of miners ....etc

A ZigBee and ZigBee-to-IR Device Control Scheme for Single Media Multi Devices


Abstract

This paper has a background of SMMD (Single
Media Multi Device) control technology for causing various
actual feeling effects about one media source. SMMD technology
adds metadata controlling arbitrary multiple devices in one
MPEG-4 media. A home server produces a control command
from metadata and delivers control message to a sensory effect
device using the ZigBee comm ....etc

1.1 INTRODUCTION
Overall optimization of a coal-fired power plant is a highly complex process. One must first decide what constitutes optimal performance. Obvious answers include maximum thermal efficiency, lowest possible emissions, lowest possible cost, readily marketable by-products, and maximum system availability for power generation. In reality, these goals—and others—are interrelated. In some cases, however, these optimization goals are at odds with each other. For example, high excess air will result in b ....etc

DESIGN OF MONITORING SYSTEM FOR COAL MINE/ OPEN MINE SAFETY BASED ON WIRELESS SENSOR NETWORK
OBJECTIVE:
 The foremost critical task for coal mine is of keeping track of miners spread out across a large mining areas.
 Many mines use a radio system to track miners, but when a collapse occurs, the base stations connected by a thin wire often are rendered useless.
 In this project to overcome the demerits of radio system we used wireless tec ....etc
