AUTOMATIC POWER METER
READING USING GSM NETWORK
The main aim of this project is to monitor and record the power meter reading and send the information to
the mobile by using GSM technology about the power meter reading .
Now-a-days technology has developed to a large extend. At
the same time the need for systems with automation and high security are
preferred. So, by using one of the best technologies available i.e. GSM we are
designing an automatic power meter reading system for commercial and domestic
purposes. Traditional meter reading for electricity consumption and billing
done by human operator from houses to houses and building to building. This
requires huge number of labor operators and long working hour to achieve
complete area reading and billing. Human operator billing are prone to reading errors as sometime the houses electricity power meter
is placed in location where it is not easily accessible . Labor billing job is
sometime also restricted and is slowed down by bad weather conditions. By using
this project we can avoid such problems.
This project is aimed to develop a system to provide
security by intimating the condition in the form of SMS by making use of GSM
technology. In this project we have two sections.
In section 1 For measuring energy consumed by the user we
are going to use one digital energy meter, at the same time as it uses 1unit
the count will be displayed in LCD And that particular data is stored in the
eeprom. When ever the request sms received. Then, it will send the consumed
number of units (meter reading) information to another section. The main
objective of this project is to design a prepaid energy meter system with the
help of GSM technology. In this project we are using bulbs as a load. On LCD we
are going display No of units consumed in this hour.
Section 1:
In section 2
(electricity board section) this section is placed in electricity board. Here
we are using the lpc2148 controller so internally rtc is there in this
controller. By using this rtc hourly once we are sending the request sms to the
section 1 to get the information about power meter reading. Then it will
calculate the amount and sends that information to the consumer mobile (sms)
through gsm modem. Here we are maintaining the last month details in a data
base (in eeprom).
Section 2:
Every system is automated in order to face
new challenges in the present day situation. Automated systems have less manual
operations, so that the flexibility, reliabilities are high and accurate. Hence
every field prefers automated control systems. Especially in the field of
electronics automated systems are doing better performance.
Probably the most useful thing to know about the global system for
mobile communication is that it is an international standard. If you travel in
parts of world, GSM is only type of cellular service available. Instead of
analog services, GSM was developed as a digital system using TDMA technology.
