互联网智能终端虚拟外设接入方法

Connection methods of virtual peripheral-based Internet intelligent terminals

阐述了嵌入式系统现有的三种互联网接入方案,并在分析和比较各种接入方式的优缺点后,重点介绍了一种新的基于IP2022虚拟外设的TCP/IP智能终端接入技术方案、设计步骤和具有以太网接口的指纹识别智能模块应用实例。实际应用表明:该方案实现可行、设计简单、成本低廉,而且应用软件设计方便。

This paper clarifies three methods of Internet connection of the existing embedded systems. After analysis and comparisons of their advantages and disadvantages, a new method for virtual TCP/IP peripheral-based Internet connection of intelligent terminals is discussed and applied to our fingerprint i-dentification module. Experimental result shows that this method is easy and feasible to design application software.
