 本发明的实施方式
下面结合附图及实施例对本发明所述可远程访问的网络接口移动硬盘100进行详细说明。
实施例一
本发明所述可远程访问的网络接口移动硬盘100，如图1所示，包括硬盘主体101、SoC102、存储模块、以太网PHY104、USB to SATA bridge105、高速模拟开关106、电源管理模块107、通信接口和电源接口；所述通信接口包括RJ-45接口108和USB接口109；所述硬盘主体101、高速模拟开关106、SoC102、以太网PHY104和RJ-45接口108依次电连接；所述存储模块与SoC102相电连接；所述高速模拟开关106、USB to SATA bridge105和USB接口109依次电连接；所述USB接口109、供电接口110均通过电源管理模块107与硬盘主体101相电连接。
本发明所述可远程访问的网络接口移动硬盘100，所述硬盘主体101设置一SATA从机接口；所述高速模拟开关106设置一SATA从机接口和两个SATA主机接口；所述SoC102设置一SATA主机接口和一以太网MAC层接口；所述USB to SATA bridge105设置一SATA主机接口和一USB从机接口；所述高速模拟开关106设置有两个输入接口和一个输出接口；两个所述输入接口分别与SoC102的SATA主机接口和USB to SATA bridge105的SATA主机接口相连接；所述输出接口与硬盘主体101的SATA从机接口相连接；两个输入接口二选一，同时只有一个输入接口与输出接口连接。所述以太网MAC层接口与前述以太网PHY104相连接；所述USB从机接口与前述USB接口109相连接。SB to SATA bridge105完成USB协议到SATA协议的转换。在本实施例中所述硬盘主体101为SATA接口固态硬盘。所述存储模块采用DDR SDRAM103存储模块，提供SoC102运行所必需的数据缓存。所述电源管理模块107设置有输入保护模块和电源切换模块，移动硬盘100的电源可以使用供电接口110提供的外接+5V直流电源，也可以使用USB接口109提供的+5V VBUS电源，两种电源通过电源切换芯片LTC4413进行切换。
在以太网接口模式下，如图2所示，使用网线连接该移动硬盘100的RJ-45接口108和路由器200的LAN口201。与路由器200建立连接后，移动硬盘100上的SoC102会启用存储于其中的DHCP客户端服务，动态获取本机的IP地址，此时移动硬盘100接入网络中。当各智能设备和该移动硬盘100处于同一局域网之中，在已知移动硬盘100以太网MAC地址的条件下，可以很容易得到其IP地址，各类智能设备即可通过网络（有线或无线网络）与该移动硬盘100建立连接。此时选择合适的TCP/IP应用层协议，例如FTP协议，可以方便的对移动硬盘100中各类文档进行访问和读写操作。当各智能设备和该移动硬盘100不处于同一局域网内，但均处于互联网之中，需要对路由器200中的端口转发进行简单设置。例如，使用FTP协议进行文档访问和读写操作时，需在路由器200中对端口21进行端口转发，此时互联网中的各智能设备通过FTP协议访问路由器200WAN口202的地址即可实现对该移动硬盘100的访问和读写操作。因此在以太网接口模式下，各智能设备可以不受地域限制地对该移动硬盘100进行远程访问。
实施例二
在实例一所述可远程访问的网络接口移动硬盘100结构的基础上，在USB接口109模式下，如图3所示，该移动硬盘100可直接通过USB接口109接入各类智能设备或个人计算机500中，此时作为普通移动硬盘100使用。
