WIRELESS COMMUNICATION

MATERIAL AND METHODS

CONCLUSION

RESULTS AND DISCUSSION

ACKNOWLEDGEMENTS

The model proposed in this work, it communicates through

the internet WI-FI connection languages, in order to achieve

real-time monitoring, power consumption, voltage levels

provided and identification of gaps in distribution. The

proposed system held a connection with a satisfactory way on

the internet encountered difficulties, allowing having quick

answers when requested an update of the page used to access

the information.

INTRODUCTION

The structure of the tests is illustrated in Figure 2, where the

prototype is collecting, processing and sending the

information to the router that that performs the function of

concentrator and sends the data to the server. The information

sent to the server must be accessed through the laptop or

smartphone from anywhere

This research focuses on one of the aspects of the concept of

Smart grids, the Smart Meter. The majority of electrical

energy meters used in Brazil today are electromechanical, that

kind of measuring system not only provides the energy

consumption in a given period of Scouting. Only once a

month an employee of the dealership goes until the consumer

measures the consumption and delivers the Bill to consumers.

This research aims to propose the creation of a smart

electricity meter using the Arduino platform with a Wireless

communication system that allows it to communicate bi-

directionally. This will provide the realization of intelligent

management of energy, allowing the concessionaire to have

more data about their customers and meet their consumer

consumption profile, and act more efficiently.

The communication of smart meters is one of the most

important features; it will be the determining factor for change

in the provision of energy services. Due to the size of Brazil,

the technology to be adopted should take into account, price,

availability, scope and viability (MME, 2010).

Among the technologies available, we decided to give

emphasis to the PLC and ZigBee for the similarity in its

concept of operation, adapting the idea applied on the

research. Leaving this concept, this paper proposes a smart

meter with a Wireless communication system, which will act

as the collector of information by sending the data to the

adopted hub as the topology of the deployment location.

The developed prototype used as foundation the Arduino

platform, in Figure 1 are shown the components used in the

Assembly and connections made.

The results obtained through the connection of the prototype

with the network created by the router, as can be seen in

Figure 3, proved that communication is possible using the

proposed system.
