Energy Meter Per Hour Average Max and Min Load Display On LCD
Now
days there is rapid increase in the power consumption, which has given rise
to
the scarcity in the power generation. There should be an immediate change in
this
situation
are else the results cannot be even imagined. This not only results in scarcity
but
also
imposes burden on the common man. This problem can be solved by monitoring the
average
power consumption with max and min load which can help the user to monitor
the
health status of his load devices as well as to have a control over the power
being
consumed
daily. This system also helps Transco department to impose tax if the average
power
consumption per hour is more than the prescribed level by which we can control
the
consumer from wasting the power.
So
our aim in designing this device is to fulfill the multiple purposes of the
consumer
and finally impart a control over the power consumption so that there will not
be
any hazardous results in the near future due to the power scarcity. The device
input
and
output modules are controlled with help of a micro controller, which can be
termed
as
a control unit for the entire system. The energy meter is interfaced to the
microcontroller
with the help of an interfacing circuit. This interfacing circuit is
something
similar to a counter, which is capable of counting the pulses with respect to
the
power
consumed by the user. The microcontroller takes the responsibility to count
these
pulses
and derive the equivalent average, Min and Max loads for that hour duration.
The
amount
of power consumed is displayed on this LCD. In addition to this the controller
is
also
interfaced with few LED indicators.
The
design of this system is very much sensitive and should be handled with
utmost
care because the micro-controller is a 5 volts device and it is employed to
monitor
the
household power consumption per hour where it should be interfaced with a 240
volts
energy
meter. So every small parameter should be given high importance while designing
the interfacing circuit
between the controller and the energy meter. The major advantage
of
this system is its reliability to operate and a user-friendly output.
