Fault Detection System using Zigbee and Embedded base Meter Reading

The development of automatic meter reader using zigbee is presented in this paper. This system consists of zigbee digital power meter installed in every consumer unit and electricity e-billing system at the energy provider side. The zigbee digital power meter is a single phase digital kWh power meter with embedded zigbee modem which sends the power usage reading using information back to the energy provider wirelessly. The power provider side an e-billing system is used to manage all received meter reading, compute the billing cost, and update the data base and to be published billing notification to its respective consumer through wireless. The working principle, hardware and software tools are also explained in detail. A system of automatically interrogating metering without the need for site visitation has many advantages, both to the supplier and to the consumer. This paper presents a case study of the design of such a system starting from scratch. The system design begins with interfacing the metering to a communications system. The development of an interface for an automatic meter reading system is described. In this case study, the power lines in a power system are used as the communications channel. A smart meter is the source of power data and communicates with a logging PC when interrogated. What is involved in the initial design process is described. Serial communication is used to collect the instrument data and to communicate with the logging PC. Specialized circuits in this design that make use of FSK are identified and the entailed implementation problems are described. Measurements of the interface’s output are given.
