POWER AWARE CLOUD METERING

AIM

Updating of power consumption data In domestic/industrial sectors using GPRS/ GSM

INTRODUCTION

• Now a day’s Many real time applications connected to web (internet).

• This is very useful and helpful for customers to see application (requirements) from anywhere in the world.

• These web connected applications belong to server client model.

• Data transfer to web server is done through GPRS (General packet radio services) communication.

EXISTING SYSTEM

• Electricity is a commodity required to run most home appliances.

• Electricity cannot be seen hence a consumer has no idea about the amount of energy consumed until he/she receives a monthly/yearly electricity bill.

• Even monthly bills do not breakdown the consumption to an appliance level therefore users have insufficient information to identify the energy guzzlers in their homes.

PROPOSED SYSTEM• In this project we can get updating of domestic electrical

power consumption. • Here we connect energy meter to microcontroller.

Microcontroller gets pulses from meter according to power consumption.

• For every ten units microcontroller generates one TCP stack with standard data format.

• Other end of microcontroller GSM/GPRS modem is connected. This modem updates TCP stack information to web server and same data updates can also be sent to any mobile.

• This is very useful to monitor power consumption remotely from anywhere in the world.

BLOCK DIAGRAM EXPLANATION

• POWER SUPPLY : 230v ac input supply converted into +5v dc using various converters.

• GSM/GPRS: SIM900 GSM modem used which has band width of 900/1800/1900mhz. GSM modem requires “at” commands o initialize.

• MAX232: It is a intermediate device which convert CMOS logic level to RS232 logic level bi-directionally. In this project it is used as external device o reconvert.

• 16F877A: It is a microchip 8 bit microcontroller called as PIC (Peripheral Interface Controller) versions. It has 8KB flash ROM, 368 bytes of SRAM, 256 bytes of EEPROM with in built 10-bit ADC, USART, MSSP, PSP communications. IT is 40 – pin PDIP IC with 33 I/O bits (5 ports).

• 16X2 LCD: It support alphanumeric characters (0-9, A-Z, a-z), punctuations(.,?@#%). It has 2 lines and 16 characters for every line with font size of 5x7 matrix.

APPLICAIONS

1. Domestic applications such as energy meter reading.2. Commercial applications 3. Industrial applications 4. Smart grid applications5. Water meter reading applications.6. Industrial & domestic gas consumption readings.

ADVANATAGES

• The system designed reduces the efforts of manual data collection of energy meter. Also, data which is received at service provider side is easy to manipulate for bill generation and other such tasks.

• With this system we can collect the reading as well as control the supply to the user.

• With addition of software at service provider side, the customer can be informed of current meter reading, bill for current cycle, status of the line and other parameters to the customer with either message or a phone call
