Transcript of GSM Based Automatic Energy Meter Reading

Major Building Blocks
Microcontroller based control system with regulated power supply.
GSM Modem for remote communication.
Digital Energy Meter.
LCD Display to display the meter readings.
Precise consumption information
Clear and accurate billing
Automatic outage information and faster recovery
Better and faster customer service
Flag potential high consumption before customer gets a high bill.
The Microcontroller based system continuously records the readings and the live meter reading can be sent to the Electricity department on request. This system also can be used to disconnect the power supply to the house in case of non-payment of electricity bills. A dedicated GSM modem with SIM card is required for each energy meter.
Automatic meter reading (AMR) system is an effective way of data collection, that allow substantial saving through the reduction of meter read, greater accuracy, improved billing, reduced tempering.
The purpose of this project is to remote monitoring and control of the Domestic Energy meter. This system enables the Electricity Department to read the meter readings regularly without the person visiting each house.
An energy meter is a device which is used to measures the consumption of energy of any residence or other industrial establishment.
Sending personnel into the field to record usage is expensive and prone to human error. Add the complexity of having to record usage during several tariff periods, and the burden becomes unacceptable. Some form of automated reading is needed.

Guided By :- Dr. Y. N. Trivedi

Major Building Blocks
Microcontroller based control system with regulated power supply.

GSM Modem for remote communication.

Digital Energy Meter.

LCD Display to display the meter readings.
Tri-band GSM/GPRS engine.
Works on Frequencies EGSM 900 MHz, DCS 1800 MHz and PCS 1900 MHz
SIM300 provides GPRS multi-slot class 10 capability and support the GPRS coding schemes CS-1, CS-2, CS-3 and CS-4.
Current Consumption - 2.5mA in SLEEP mode.
GSM Module
AT Commands
Customer Benefits
Further Extensions
GSM based energy meter is easy to installation and beneficial for both energy provider and consumer.
AMR also gives the information of total load used in a house on request at any time.
The statistical load used and profile can help customer manage their energy consumption.
This device has the capability to revolutionize the energy meter market and will become help to country revenue by stopping the current theft and punishing the dishonest customers.

VCC Digital supply voltage.
GND Ground.
Port A (PA7..PA0) , Port B (PB7..PB0) , Port C (PC7..PC0) , Port D (PD7..PD0)
Analog inputs to the A/D Converter.
8-bit bi-directional I/O port, if the A/D Converter is not used.
The Port output buffers have symmetrical drive characteristics with
both high sink and source capability.
The Port pins are tri-stated when a reset condition becomes active,
even if the clock is not running.
A low level on this pin for longer than the minimum pulse length will
generate a reset, even if the clock is not running.
XTAL1 Input to the inverting Oscillator amplifier and input to the
internal clock operating circuit.
XTAL2 Output from the inverting Oscillator amplifier.
AVCC AVCC is the supply voltage pin for Port A and the A/D
Converter. It should be externally connected to VCC,
even if, the ADC is not used. If the ADC is used, it should be
connected to VCC through a low-pass filter.
AREF AREF is the analog reference pin for the A/D Converter
