For making a unit price card for Rs 2. This is nothing but meter reading. It offers flexible settings for both metering and payment and user-friendly interface to both the service provider and the end consumers. For both the meters, reading is done from left to right. The distribution company has to receive huge amounts in the form of pending bills, which results in substantial revenue losses and also hurdles to modernization because of lack of funds.
For example, during peak hours, the utility company can charge a premium rate for the non-essential appliances such as electric heater, air-conditioner and washing machine using the tariff switching functionality. However, unlike , a single quota is allocated for the entire group. The benefits of these systems are; improved operationalefficiencies, reduced financial risks, better customer service. This digital prepaid energy meter does not have any rotating parts. There are clear results from many countries where a prepaid system has reduced the usage wastage by a large amount.
This paper presents a framework to restrict groundwater pumping by implementing an annual individual electricity quota without interfering with the electricity pricing policy. The microcontroller is programmed such that a counter is kept incrementing for every pulse rate, which gives the value of the energy consumed. Defining a Prepaid Energy Meter System: Basically like in a mobile phone recharging, the consumer buys a recharge card and gets some energy units in return of the balance amount. Finally, Section 4 provides conclusions and directions for future work. Performing these two tasks is getting difficult nowadays because of the rapid development in the electronics world. In addition, the information exchange between Smart Meter and the Core Network can be encrypted by the shared encryption keys received during authentication.
The proposed solution use smart cards to store keys and perform cryptographic algorithms. Present prepayment system is difficult to install and costly. 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. The balance amount will keep reducing for every unit of energy consumed and once zero, the power supply would be automatically cut off. Mobile phones have become a widespread means of communication. As shown in the , a session could be associated with multiple N services. However, the use of smart cards for utility payment systems has some major drawbacks like added cost, low availability, and risk of complete disconnection due to system failures that outweigh their benefits.
This paper features a 3-tier smart card secure solution for a novel prepaid electricity system. Prepaid Energy Meter using Smart Cards is an efficient scheme of electricity billing. For example, as shown in , peak rate is applied after 6 pm. In this project we have given the name formemory card as a 16-bit digit. Most of the time they have complaints regarding statistical errors in their monthly bills.
Normally the microcontroller gives a high signal to the input pin of the relay driver, which develops a logic low signal at its corresponding output pin and the relay coil is energized, thus connecting the load to the main supply. Insert the card into the Programmer 2. Energy meters are of two types — Electromechanical Meters and Electronic meters. The prepaid card communicates with the power utility using mobile communication infrastructure. It is a 3-tier implementation. The microcontroller stores the number of units allocated and measures the energy consumed. In addition, it performs additional pricing and load control activities in conjunction with the backend infrastructures.
The red led will blink for every key press 4. Using the proposed scheme that supports tariff switching, charging of multiple services in a single session, rating groups, utility operators can perform various demand response programs effectively and efficiently with minimum additional costs. Card reader is interfaced with the micro controller using a serial interfacing. Tata Power plans to introduce pre-paid electricity in Delhi. There is a more recent version of your browser available.
It proactively conducts many context-aware operations in the background without user's explicit requests. Go to our Resources and Help section for instructions on. Energy Meter Reading Power consumed is shown by the energy meter in form of 1 unit or 1 kilo watt hour of energy consumed. Another advantage of the prepaid. This paper studies the paradigm of pervasive commerce p-commerce and presents the design of a p-commerce system architecture which consists of e-commerce servers and store sensors.
