图 1为本发明实施例提供的一种无线 SD卡型处理装置的示意图。 如图 1 所示, 该装置设置在一个具有与标准 SD 卡外形和接口相同或兼容的卡体 内, 并且该装置具体包括接口控制器 11、 存储器 12、 存储卡 13和无线通 信模块 14。 另外, 该无线 SD卡型处理装置中还包括保证系统正常运行的各 种电路单元。
接口控制器 11用于控制无线通信模块形成自建热点,并控制存储卡的 数据下载到热点覆盖范围内 WIFI设备中或接收 WIFI设备的访问信息, 还用 于控制整个装置的正常工作并且为软件运行提供稳定的平台, 进一步还用 于自建动态主机配置协议服务或自建网站服务器服务或自建域名解析服 务;存储器 12用于提供所述接口控制器所需的程序存储空间和程序运行空 间; 存储卡 13用于存储海量的数据文件; 无线通信模块 14形成自建热点, 提供接入所述热点服务, 并为所述热点覆盖范围内无线相容性认证 (Wireless Fidelity, WIFI )设备提供数据上传或下载服务。
其中, 接口控制器 11作为该无线 SD卡型处理装置的控制中枢与数据处 理单元, 运行操作系统, 运行 WIFI以及系统中其它硬件的驱动程序, 运行各 种应用程序。
接口控制器 11分别与存储器 12、 存储卡 13和无线通信模块 14相连 接, 而且接口控制器 11 还可与外接的电源模块或外接的第三方设备相连 接。 所述连接可具体为:
接口控制器 11通过第一接口, 即 SD设备接口, 与外接的电源模块或 外接的第三方设备相连接; 通过第二接口, 即 SD主机接口及其兼容接口, 与存储卡 13相连接, 第二接口可包括 SD/MMC/CFHost及其兼容接口; 通过 第三接口, 与所述无线通信模块 14相连接, 典型的第三接口包括安全数字输 入输出( Secure Digital Input and Output, SDIO )接口、串行夕卜设接口( Serial Peripheral Interface, SPI )接口或通用串行总线 ( Universal Serial Bus, USB)接口; 通过第四接口, 夕卜 存储接口 (External Memory Interface, EMI ) ,与存储器 12相连接。
下面从两个方面详细说明该无线 SD卡型处理装置的工作原理。
第一, 当接口控制器 11通过第一接口与外接的电源模块相连接时, 该外 接的电源模块为该无线 SD卡型处理装置提供电源。
在启动系统后, 接口控制器 11控制无线通信模块 14设置为无线接入点 ( Access Point , ΑΡ ) 模式, 并启动动态主机设置协议 ( Dynamic Host Configuration Protocol, DHCP) , 网站月良务器 WEB server和域名解析系统 (Domain Name System, DNS) , 形成了一个带有网站服务功能和域名解析功能 的无线热点, 在该热点无线覆盖范围内广播热点信息, 可以为 WIFI设备提供 热点接入服务。 典型的 WIFI设备是带有 WIFI功能的智能手机, 平板电脑, 笔记本等。
该装置提供的热点接入过程具体为: 在接口控制器 11上运行 DHCP, 为接 入本装置的 WIFI设备提供动态 IP地址分配服务, 以此来保证该热点和 WIFI 设备在同一局域网内; 在接口控制器 11上运行 WEB server, 可以为接入本装 置的 WIFI设备提供网站服务, 而且接入该热点的 WIFI设备可以通过浏览器 访问 WEB server以及存储卡 13中的数据; 在接口控制器 11上运行 DNS, 可 以为 WIFI设备浏览器中输入的域名提供域名解析与 IP地址重定向服务, 当 WIFI设备通过浏览器访问该热点时, 可以将 WI F I设备浏览器上的网址解析到 WEB server上。
一个 WI F I设备检测和接入到该热点。 当热点与 WI F I设备连接后 , WIFI 设备可以通过浏览器或者客户端访问存储卡 13 内的信息, 同时接口控制器 11将存储卡 13内的信息通过无线通信模块 14下载到热点覆盖范围内的 WIFI 设备中,从而实现了将存储在存储卡 13的信息传递到热点覆盖范围内的 WIFI 设备的目的。 第二, 当接口控制器 11通过第一接口与外接的第三方设备相连接时, 该第三方设备利用行业标准接口对存储卡 1 3进行读写,并且可以为该无线 SD卡型处理装置供电。其中,该第三方设备可以为数码相机或 SD读卡设备。
接口控制器 11启动系统, 第三方设备在接口控制器 11的控制下通过第 一接口和第二接口将数据写入存储卡 13 中或从存储卡 13 中读出。 当第三 方设备的数据写入存储卡 13 中后, 接口控制器 11可以控制无线通信模块 14 形成一个无线热点并在该热点覆盖范围内广播热点信息。 当热点与 WIFI 设备连接后, WIFI设备可以通过浏览器或者客户端访问存储卡 1 3 内由第三 设备所写入的信息, 同时接口控制器 11将存储卡 1 3内由第三设备所写入的 信息通过无线通信模块 14下载到热点覆盖范围内的 WIFI设备中, 从而实现 了将第三设备的信息传递到热点覆盖范围内的 WIFI设备的目的。
因此, 本发明实施例公开的无线 SD卡型处理装置, 通过接口控制器和无 线通信模块自建热点并自主提供接入热点服务, 可以将存储卡内或第三设备 的数据与该热点覆盖范围内的 WIFI设备进行传输和交互, 同时使得该装置具 备了独立组网或独立工作的能力。
图 2为本发明实施例提供的另一种无线 SD卡型处理装置的示意图。 图 1 所示的无线 SD卡型处理装置无论结构还是工作原理, 均与图 1 中所述的无 线 SD卡型处理装置相同, 只是图 1中的存储卡 1 3由卡槽代替, 存储卡插入 卡槽 23中。 因此有关结构和工作原理不再详细说明。
因此, 本发明实施例公开的无线 SD卡型处理装置, 通过接口控制器和无 线通信模块自建热点并自主提供接入热点服务, 可以将插在卡槽的存储卡内 或第三设备的数据与该热点覆盖范围内的 WIFI设备进行传输和交互, 并且使 得该装置具备了独立组网或独立工作的能力。
综上所述, 本发明实施例公开的无线 SD卡型处理装置,通过接口控制器 和无线通信模块自建热点并自主提供接入热点服务, 不再依赖第三方的网络 资源, 而且其传输的数据均来源于或者存储于该装置的存储卡或存储设备 上, 该装置通过读写存储卡或者存储设备中的信息, 通过无线通信模块进 行传输,任何可以接收到热点信息的 WIF I设备在通过安全鉴权之后均可以 与该装置进行数据传输; 其次, 该装置的外观尺寸和接口电气性能遵循 SD 卡相关的技术规范, 可以在支持标准 SD卡的读卡设备中使用。
以上所述的具体实施方式, 对本发明的目的、 技术方案和有益效果进行 了进一步详细说明, 所应理解的是, 以上所述仅为本发明的具体实施方式而 已, 并不用于限定本发明的保护范围, 凡在本发明的精神和原则之内, 所做 的任何修改、 等同替换、 改进等, 均应包含在本发明的保护范围之内。
