1.ABSTRACT:
In this work, a safe Coal Mine Monitoring system which replaces
the traditional coal mine monitoring systems which tend to be wired
network systems. This play an important role in coal mine safe production.
With continuous enlarging of exploiting areas and extension of depth in
coal mine, many laneways become monitoring blind areas, where are lots of
hidden dangers. Moreover, it is inconvenient to lay cables which are
expensive and consume time. In order to solve the problems, we designed a
coal mine safety monitoring system based on wireless sensor network,
which can improve the level of monitoring production safety and reduce
accident in the coal mine. XBee technology provides a direction for
scientists who commit to solve the safety monitoring problems of coal
mine.
2.OBJECTIVES:
Since the main intension of this projects is to design “Metal &
poisonous
gas
Detecting
and
Alerting
System
Using
XBee”.
In under ground mining to fulfill this application there are few steps that has
been performed .

4. METHODOLOGY:
A general block diagram of the proposed scheme is given in
Figure .The whole system is divided into two parts-transmitter and receiver.
In the transmitter part the Metal & poisonous gas Detector, when the metal
or & poisonous gas is detected the it gives the signal to the ARM , then the
ARM will send the information to another receiving station through XBee
which is in concern staff or security office . At the same time ARM will
generate the out put that is fed to buffer IC 4050 ,buffer stores and given to
the driver IC 2003 in driver current will amplifies and voltage will inverts
with the help of Darlington pair circuit of driver IC to drive the relay .
Then signal is
given to the output load for indication purpose .
When ARM receives the data from the XBee, it will enable the alert
through the Buzzer in receiver side .
5. ADVANTAGES & DISADVANTAGES:
 ADVANTAGES:
1.
More useful in remote areas.
2.
Firing events more help full to save.
3.
This project we can operate Easily
4.
Can be used globally.
DISADVANTAGES:
1.
Under the mine the personal safety of staff problem.
2.
Personnel positioning problem
6.APPLICATIONS:
1. This project can be implement in gas Industries .
2. It is used in mining of coal & other materials.
3. It is used in municipal gas distribution .
4. This project can be use in Military applications.
5. It is used in nuclear power station.
7.CONCLUSION:
In this work we have proposed an efficient autonomous system for
standoff explosive detection like metal & poisonous gas. While comparing
with traditional systems have lot of advantages. The main advantages are its
miniature size, low power consumption, distributed operation, and easy
implementation.
