Embedded Network Electric Energy Measure System Based On ARM

Watthour meter is one of the instruments whose yield is the largest and it is the most comprehensive used, but now, we want multifunctional watthour meter along with changes in power supply and power consuming policy. The current electronic watthour meter designed based on 8bit MCU can not meet the needs of the constantly developing power supply and power consuming market, because of its fatal limitation on data processing speed and data bandwidth. In a word, designing network watthour meter based on high performance MCU and TCP/IP suite is the heading development trend of watthour meter.Embedded system technology is one of the most pop techonlogy in the field of ecectronic design, which is widly used in industrial control, Intellectual traffic, Infromation household appliances, public service and so on, it is having an far-reaching effect on our pervasive computing era.Samsung S3C44B0X 16/32-bit RISC microprocessor is designed to provide a cost-effective and high performance embedded SoC micro-controller solution for hand-held devices and general applications. S3C44B0X is developed using a ARM7TDMI core, 16/32-bit RISC processor designed by Advanced RISC Machines, Ltd. By providing a complete set of common system peripherals, the S3C44B0X minimizes overall system costs and eliminates the need to configure additional components.Linux comes out from 1991 to now, it has developed into powerful and perfect operating systems in a short period of shorter than ten years. Linux can compete with the traditional commercial operating system, and in new developing embedded operating system field.it is developing at full speed too,because of its advantage of open source code, extensive hardware support, rich resource, u Clinux is exactly the outstanding one of embedded Linux family, specificially designed for MMU-less MCU.Designing electric energy measure system based on ARM-u Clinux embedded platform, can solve the processing speed problem of traditional 8/16bit single-chip computer, still can design and develop the network watthour meter...
