Abstract:
The use of wireless automation in almost all the
fields of power, gas and water generation, distribution and billing
has come of age. Here with the inclusion of wireless
communication with the automation may lead to paradigm
change in the current trend. The design presents a new
methodology for avoiding the high construction and maintenance
costs in the existing meter reading technology. Apart the use of
wireless meter reading with network technologies has become
need of the day. The designed system avoids the human
intervention in Power Management. The Consumer has to pay
the bill in time, if couldn’t, the power connection may be
disconnected automatically from the remote server. It displays the
corresponding billing information on LCD and data is sent to the
server through the GSM Module. The ARM7 based hardware
system consists of a processor core board and the peripheral
board. The entire programming for microcontroller operation is
based on Embedded C Language.
INTRODUCTION
With the rapid developments in the Wireless
communication technology by the use of microcontrollers,
there are many improvements in automating various
industrial aspects for reducing manual efforts. The
traditional manual Meter Reading was not suitable for
longer operating purposes as it spends much human and
material resource. It brings additional problems in
calculation of readings and billing manually. Now-a-days
the number of Electricity consumers is increasing in great
extent. It became a hard task in handling and maintaining
the power as per the growing requirements. Presently
maintenance of the power is also an important task as the
human operator goes to the consumer’s house and produces
the bill as per the meter reading. If the consumer is not
available, the billing process will be pending and human
operator again needs to revisit. Going to each and every
consumer’s house and generating the bill is a laborious task
and requires lot of time. It becomes very difficult especially
in rainy season. If any consumer did not pay the bill, the
operator needs to go to their houses to disconnect the power
supply.
SYSTEM ARCHITECTURE
The high level block diagram of the wireless meter
reading system is shown in the Figure.1.The Power Supply
section supplies all other components with required Power.
The ARM7 LPC2148 microcontroller module takes the data
from the energy meter and performs the necessary control
operations like breaking the circuit through Relay control
unit and the required information to the mobile phone via
the communication module [2] GSM
Energy meter
Energy meter module is composed of ADE7757
which is energy metering IC with integrated oscillator and
load and which produces the analog signal can be converted
into digital signal and that digital signal in the form of
pulses and ADE7757 outputs average real power
information [11] based on the load. These outputs are
interfaced with the LPC2148.One of the
feature in
ADE7757 to enhance the capability of this work is having a
power supply monitoring circuit on the VDD supply pin of
the ADE7757. Due to this, proper device operation [6] is
achieved at power up and power down modes. High degree
of immunity to false triggering from noisy supplies is
attained due to built in hysteresis and filtering operations in
power supply monitor of the ADE7757.
CONCLUSION
In the present work wireless meter reading system is
designed to continuously monitor the meter reading and to
shut down the power supply remotely whenever the
consumer fails to pay the bill. It avoids the human
intervention, provides efficient meter reading, avoid the
billing error and reduce the maintenance cost. It displays the
corresponding information on LCD for user notification.
