Remote Meter Reading System Based On Ethernet

With the development of economy and the improvement of people's living standards, various meters, such as ammeter, water meter and gas meter, are used more widely. At the same time, reading the meters has become a mass and troublesome work. Traditional ways no longer adapt to the development of society any more. However, with the help of computer technology and communication technology, it's possible to read meter automatically. Many kinds of AMR (Automatic Meter Reading) systems come to existence, which not only substitute the manual work but also establish the base for better service.First, this paper introduces some familiar AMR systems, analyzes their characteristics and efficiency, and gives a remote meter reading system solution which is based on Ethernet. Then it introduces the Ethernet technology and Ethernet AMR system specially, pointing out it's a promising AMR technology. And it also describes the design of the two AMR controllers in detail, which are based on Rabbit2000 MCU and S3C4510B MCU. At the end of this paper, it depicts the difficulty in our AMR system and the future development of AMR technology.
