In the recent years, we have seen the emergence and the growing of the e-business via the internet. Organizations are implementing various infrastructures that allow them to have secure e-business transactions. There is a more recent version of your browser available. If the programming done sucessfully then the Green led will long Blink finally. Our policies of its distribution are also partially responsible for this because we are still not able to correctly estimate our exact requirements and still power theft is prevailing. When the amount is over, the relay will automatically shutdown the wholesystem. This study is then used to present a similar prepaid charging scheme for smart metering to be used in Smart Grid.
This system will provide reliability and increase security. This process is a time taking and risky process. Sathish on +91 8885507011 or you can email us on thank you,i am designing the prepaid water meter for my final year project. The operational procedures of the system are discussed in the subsequent paragraphs. Also the consumer can deliberately consume more amount of power than required and still refrain from paying the bill and nothing can be done to severe the electric power supply. Some tags can be read from several meters away and beyond the line of sight of the reader.
The main drawback of this system is that person has to go area by area and he has to read the meter of every house and handover the bills. Prepaid Energy Meter Using Smart Card Project. And once again please visit our domestic website and international website For more details please contact to Mr. If the available credit is exhausted then the supply of. With the advent of new Smart Grid applications like Demand Response and Plug-in Electric Vehicles, the utility operators need to profoundly change the way prepaid energy systems operate by bringing telecommunications to the core of their activities. In this project we have given the name formemory card as a 16-bit digit.
In India, the State of West Bengal has decided to introduce the smart cardoperated prepaid energy meters in remote islands of Sunderbans. Its applications include shopping malls, residential townships, commercial buildings, employee quarters etc. To put some light on the difference between smart grids and traditional utility grids, some aspects of the traditional utility grids are covered in this paper as well. Based on the usage of power we need to recharge the card by placing it in the card reader. A prototype for customer terminal is successfully constructed. Still accuracy cannot be guaranteed as there can be errors in human reading.
Even though digital meters are being replacing conventional electromechanical meters and provide much accurate readings, still the problem of deliberately making a false reading can exist political reasons. One of the applications in this particular point of view is using the smart card to buy energy. Go to our Resources and Help section for instructions on. Using a smart metering infrastructure with a centralized authentication and charging system, a utility operator can eliminate most of the above mentioned drawbacks and increase the adoption of prepaid energy meters to a large extent. Therefore, no mobile communication network is needed. A firewall is used to separate the network domains. Energy meters are of two types — Electromechanical Meters and Electronic meters.
Prepayment metering system had improved operational efficiencies, Reduced financial risks and provides better customer service. As we know that today time is important and everyone wants to be out of the long billing queues as everyone is in hurry so we bring scheme of recharging meter just as we charge our cellular mobiles. However, the security of the fingerprint data is particularly important as the possible compromise of the data will be permanent. Electricity bill can be paid using prepaid electricity billing system. Since the supply of power is limited, as a responsible citizen, there is a need to utilize electricity in a better and efficient way. The prepaid card communicates with the power utility using mobile communication infrastructure. The energy meter supplies pulses to the microcontroller for every unit of energy consumed.
Another paper features a 3-tier smart card secure solution for a novel prepaid electricity system. The benefits of these systems are; improved operationalefficiencies, reduced financial risks, better customer service. Considerable amount of revenue losses can be reduced by using Prepaid Energy Meters. The increasing computational power placed on the chip along with advances in cryptography has made the smart card a very powerful tool for identification. All the consumer has to do is to display the card in the front panel of the meter for a time of 3 seconds. Experiences and lessons learned from this formal development process are discussed. The system could be monitored online through prepaid electricity meters.
There are clear results from many countries where a prepaid system has reduced the usage wastage by a large amount. A relay system has been used which either isolates or establishes the connection between the. A compromised node may leak a master key, or may give the attacker an opportunity for injecting faulty messages. The current paper, however, demonstrates that Shieh-Wang's scheme does not provide perfect forward secrecy and is vulnerable to a privileged insider's attack. Block diagram of a simple smart metering circuit Analogue to Digital Converter.
Here, only the network entities relevant to the prepaid charging model will be discussed. Now you have got an idea about the concept of prepaid energy meter if you have any queries on this topic or on the electrical and leave the comments below. In our project we also have a provision to give an alarm sound to consumer before the whole amount is reduced. The consumers can also demand at any time to check the amount of consumed energy so that a record of their energy usage can be obtained. The people working in these boards will go on a particular day and do their.
Many organizations are extending their business transactions by using the Web. As shown in , Rating Groups are formed by a group of services from a particular user. Authorization for the prepaid session and quota replenishing occurs at the home network as well. A high percentage of electricity revenue is lost to power theft, incorrect meter reading and billing, and reluctance of consumers towards paying electricity bills on time. Many protocols and frameworks have been proposed and implemented to provide secure and trusted exchange between parties involved in the transaction. In this paper, we propose a framework based on smart card that allows partners to realize secure transactions. In addition, it performs additional pricing and load control activities in conjunction with the backend infrastructures.
