Smart power meter using zigbee technology

摘要

Present invention provides specially a wireless smart power meter using Zigbee is proposed for automatic meter data collection, give intimation through messages displayed on LCD and energy auditing. It is the ARM7 Processor based system which continuously records the readings and automatically takes the responsibility of calculating the bill. In this invention Zigbee has major role in monitoring and for efficient power utilization. Zigbee technology is used to convey the electricity bill through message or internet to the consumer automatically. It covers enough area needed for communication and it works on low data rate of 20Kbps to 250Kbps with minimum power consumption. This will enable two- way and real-time communication between the consumers and the provider. The RFID card reader is used for payment of the bill. The theft detection technique is used to detect the illegal use of electricity. It will help to minimize the cost of electricity bill. ARM Processor is used for the theft detection.Following invention is described in detail with the help of Figure 1 of sheet 1 shows Block Diagram of Smart Power Meter using Zigbee Technology, Figure 2 of sheet 2 shows Zigbee Communication Network and Figure 3 of sheet 2 shows Block Diagram of RFID.
