嵌入式网络仪器的设计和实现

以一种嵌入式图像采集系统为例，从硬件组成和软件设计两方面介绍了嵌入式网络仪器的设计和实现。系统利用微控制器SX52作为控制芯片，控制整个系统的运行；以图像采集模块DB200完成对图像信号的采集；用以太网控制器RTL8019作为网络接口芯片，实现网络传输的底层功能。软件方面进行了传送协议实现、仪器远程控制和系统软件的设计，接入以太网，组成嵌入式网络仪器。该系统实现了远程数据网络共享的方法，完成图像的远程实时传送，为广泛应用的嵌入式系统的Internet化提供了一个解决方案。

Study and Implementation of Embedded Network Instrument

Took a kind of embedded picture gather system as the example, had introduced the design of the embedded network instrument and realized from the hardware and soft program design. Utilized a SX52 as the Micro Control Unit to control the running of the network instrument system, utilized a module DB200 to finish the gathering of the picture, utilized a network controller RTLS019 as the device to connect Intemet to achieve the basement function of the network transmission. The software carried on the transmission protocol realization, the instrument remote control and the system software design, so connected the ethernet to made up the embedded network instrument. The immanent realized the sharing data based on intemet and transmitted the picture long-distance real time. It is a good solution method for the widely-used embedded system connected to Internet.
