With the improvement of people's living standard, household appliances replacement, function more and more, at the same time is followed for" electric" demand. While the ordinary family, metering electricity device, is the general electric meter. Scientific and technological level at the same time, electricity metering system also will be development. From the earliest meter reading charge ( induction type mechanical watt-hour meter, a month will have full-time personnel door, manual meter reading charge ). Because of its complicated operation, waste of labor also may copy the wrong, wrong, such as omission of many problems. Born is the smart meter, smart meter development is the use of multiple environmental (computer technology, communication technology, to create intelligent chip as the core, with electric power calculation and management function of the meter. )
As the meter charges, the most important one is the charging system and electronic device connection between. How simple, convenient for the public to enjoy the service, is the main purpose of the meter replacement. Now the mainstream of the charging system are the following: IC card electric meter collect fees system, electric power carrier remote automatic meter reading system. But no matter which kind of charging method corresponding there will be unavoidable accidents, such as interference and other issues.
Therefore, the smart meter charge is still a need for the development of the subject for a long time, how to make it popular in the community, at the same time, convenient and safe and accurate work, is that we need to study the work of
