| 摘 要： | 终端根据用户权限，切换硬盘并与物理隔离控制器交互网络请求信息，从而将用户机接入相应的网络．终端采用C8051F226单片机作为控制器，读SLE4442数据实现身份认证，控制EPM7064切换硬盘，并通过RTL8019AS与物理隔离控制器交互网络请求．测试表明：方案可行，运行稳定。

| Abstract: | According to user's purview,the terminal switches the hard disk and communicates network request with the physical isolation controller,then the controller links the PC to the corresponding network.The terminal uses C8051F226 as the MCU,reads SLE4442's data for identity authentication,controls EPM7064 to switch the hard disk,and communicates network request with the physical isolation controller via RTL8019AS.Tests suggestes that the scheme is feasible and its operation is steady. |
