The role of embedded systems in the field of industrial control and more obvious . AVR 's performance , especially in the 8 -bit embedded processor , and μC/OS- Ⅱ embedded operating system open source , perfect function , the code is simple and easy to apply , so the combination of both the applied research hotspot . With the growing popularity of networked embedded systems began to join the Ethernet interface , so that the entire system and intelligent network into one . Battery as a constant power supply , stable performance , low cost , long life time and so , it is widely used in the industrial field . Battery production process , the formation process is an important part of the impact on the quality of the battery . With the increase in battery demand , high-volume production spawned a network of intelligent battery into the birth of the monitoring system . The subject is based on the AVR μC/OS- Ⅱ platform to research and design a functional expansion with an Ethernet interface into the battery monitoring system , the main contents include : 1 . Hardware system design . Mainly discusses the AVR processor ATMEGA128 core foundation as a data acquisition interface to the watt-hour meter chip CS5460 RTL8019 network interface circuit design also includes a memory interface circuit design , D / A control circuit design . Software system design . Completed μC/OS- Ⅱ cuts , depending on the hardware configuration and transplantation , the completion of the various parts of the driver , such as serial port driver , CS5460 driver ; modify the network card driver ported uIP protocol stack to achieve the system network access is preliminary . Design multi-task management application , and strive to stable performance , clear structure and high portability . The prototype realization of the basic functions of the battery into monitoring . Through this issue , increase the experience for the development of practical applications , and to deepen the understanding of embedded systems applications .
