Abstract


Automatic Meter Reading is a new technology which applies data acquisition, transmission and processing to water, power, and gas’ supply and management. With AMR, the traditional manual meter reading shortcomings can be overcomed and new hope is brought. The AMR systems are developed late in our country but progressing fast. With management revolution in the water, power and gas management, the AMR research is becoming a trend.Embedded system industry is continuously developing swiftly and violently in these years, which has been widely applied to many fields, such as mobile computing device; network device, industrial device, information appliances, automobile electronic, amusement establishment, apparatus and instruments, etc. As a communicating method, GPRS is a new technology, it has good effects, lower price than SMS and can be improved smoothly. Meanwhile, GPRS supports TCP/IP protocol and can make wireless data transmission convenient.In this background, we integrated embedded system and embedded Linux technology together and architected embedded uClinux system based on ARM7TDMI core microprocessor S3C44B0X. A software and hardware platform has been established.This paper introduces some familiar AMR systems home and abroad, analyzes their characteristics at first. Then analyzes the frame of common AMR systems and describes the way of upward/downward communications in detail. Chapter 3 introduces the Ethernet AMR system specially, pointing out it’s a promising AMR technology. After that, describes the design of the controller in detail, both hardware and software. The MCU used and embedded system established are also introduced in detail. As a part of an embedded system, bootloader, some device driver programs and application programs are amended and designed. Finally, the summary and some problems of the design are given, in order that with further study, the system can be made better.
