ABSTRACT
CALCULATING THE METER READING BY MANPOWER
Inefficient system of billing and collection
Less efficient, error prone and costly
CALACULATING THE METER READING USING GSM
Provides billing details on merely giving a miss call
Project comprises of GSM module SIM-300
Works on three predefined frequencies
Microcontroller AT89S52 with energy meter to read the units
introduction
Present power usage reading is done manually
Reguires large no of labour operators
Long working hours to accomplish the work
Printed billing may get lost
Delayed due to bad weather
Prone to error
Through GSM
Electricity used is calculated by energy meter
Passed to microcontroller(8051)
Then to GSM modem
Whole process is error free
COMPONENT USED
Microcontroller AT89S52 (8051 family)
GSM module SIM 300
Crystal Oscillator 11.0592MHz
Capacitors
MAX2332
RS232
Electric meter
Power supply
Electric Bulb
Resistors
SOFTWARE USED
Keil
Proteus
GSM TECHNOLOGY
Handles voice efficiently
Support for data and Internet applications is limited
Digital nature of GSM
Most GSM systems operate in the 900 MHz and 1.8 GHz frequency bands
In North America they operate in the 1.9 GHz band
GSM divides up the radio spectrum bandwidth by using a combination of (TDMA/FDMA) schemes
Fundamental unit of time in this TDMA scheme is called a “burst period”
A unique feature of GSM is the Short Message Service (SMS)
SIM 300
SIMCOM SIM300 is a module that connects to the specific application
SIM300 can be integrated with a wide range of applications
It is a Tri-band GSM/GPRS engine that works on frequencies
EGSM 900 MHz,
DCS 1800 MHz and
PCS1900 MHz
Provides GPRS multi-slot class 10 capabilities
Support the GPRS coding schemes CS-1, CS-2, CS-3 and CS-4
Tiny configuration of 40mm x 33mm x 2.85 mm
Can fit almost all the space requirement in our application, such as Smart phone, PDA phone and other mobile device
CONCLUSION
Proposed methodology is used to generate prepaid card for usage of electricity
Generates the message to the consumers either by day basis or weekly basis as per consumer requirements
Will minimize the wastage of electricity and saves the power for future generation
GSM network provides
Efficient wireless automatic meter reading distribution control and
Making fast billing system, accurate, effective and
Reduction of labor cost of operation
