基于以太网接口并行多通道采集器的设计

The Design of Parallel Multi-channel Collection Station Based on Ethernet Interface

基于WIN9X下IPX/SPX协议 ,提出并制订了在DOS下利用WIN9X共享文件进行信息交互的机制 ,并利用该机制 ,设计了一基于以太网接口的并行多通道采集器 ,使WIN9X主控机能通过以太网接口可靠地实现对DOS采集器的控制 ,以完成瞬态信号的采集。目前 ,利用该机制设计的采集器已成功地应用于实际中 ,它不仅避免了使用商用的TCP/IP协议栈 。

On the basis of the IPX/SPX protocol in the WIN9X, a mechanism of utilizing WIN9 X's shared files to exchange information in the DOS environment is presented. Wi th the mechanism, a parallel multi-channel collection station based on the ethe rnet interface is designed, and makes WIN9X's host computer reliably control the DOS collection station through the ethernet interface, to finish the acquisitio n of transient signal. At present, the collection station has been successfully applied in practice, it not only has the advantage of avoiding to use commercial TCP/IP protocol stacks, but also has good channel expansibility.
