摘要
本文给出了一种基于SPI总线的医疗仪器网络接口的设计方法。网络接口由PIC单片机和W5100网络芯片等组成。单片机为网络接口的控制核心,通过SPI总线接口W5100,W5100通过RJ-45接入网络,从而实现医疗仪器与网络的信息交换与控制;实验结果表明基于SPI总线和W5100的医疗仪器网络接口的硬件结构简单、性能稳定、兼容性强。
The paper introduces a design of medical instrumentation＇s network interface based on Serial Peripheral Interface （SPI） bus. The network interface is composed of PIC MicroController Unit （MCU）, W5100 network-chip and RJ-45.while MCU is the control center of the network interface and communicates with WS100 by serial peripheral interface （SPI） and consequently achieves information exchange with medical instrumentation. The results of experiment indicate that this design has the simplicity of hardware structure, high stability and firm compatibility.
