摘　　要：通过对远程抄表系统现状的研究,提出一种基于以太网及SMS模块传输的远程抄表系统方案,介绍了系统的硬件和软件的设计。通过C8051F236,控制RTL8029AS和TC35i,实现了基于以太网及SMS的通信。通过对FPGA的编程实现了C8051F236与RTL8029AS之间的PCI桥连接,并根据嵌入式系统的特点对标准TCP／IP协议进行了优化。由于SMS传输和以太网传输之间能够进行优势互补,并且两者应用十分广泛,使得该系统具有很强的可靠性及可扩展性。Through studying on current status of remote meter reading system, a strategy of system based on Ethemet and SMS module transmission is stated. Via C8051 F236, controlling RTL8029AS and TC35i, the communication based on Ethemet and SMS is implemented. By programming with FPGA, PCI bridge connection between C8051F236 and RTL8029AS is established, and the standard TCP/IP protocol is optimized in accordance with the features of embedded system. Since Ethemet and SMS transmission are widely used and their advantages are reciprocal, this system is highly reliable and expendable.
