Description

数码卡的处理方法及终端 技术领域
本发明涉及通信领域，具体而言，涉及一种数码卡的处理方法及终端。
背景技术
随着人们对手机存储容量的要求不断提高，安全数码卡(Secure Digital Memory Card，简称为SD)卡已经成为智能手机的标配。用户使用SD卡时，有时需要把SD卡中的数据往计算机里转移或更换SD卡，一般都要先取出SD卡。现在的智能手机大都支持对SD卡的热插拔，但是对于SD卡的正确使用而言，仅有热插拔是不够的。为了数据安全和设备安全考虑，在取出SD卡前，最好对SD卡进行卸载。否则在有数据读写时，直接取出SD卡，有可能对设备造成损害或者造成数据的丢失或错误。
安卓手机一般在设置应用中，在“存储”选项里可以进行SD卡的卸载，不过绝大多数用户要么不了解或是嫌这一步烦琐，一般都是直接取出SD卡。由于从android2.2之后，安卓系统支持apptosd，支持应用安装到SD卡。这样的话，很多时候即使用户没有对SD卡进行主动的读写操作，但是很多应用仍然在和SD卡进行数据交互。此时取出SD卡，就会造成数据的缺失或错误，对SD卡或SD卡中的文件造成损害。
针对相关技术中，通过热插拔取出SD卡会对SD卡或SD卡中的文件造成损害的问题，还未提出有效的解决方案。

在本实施例中提供了一种数码卡的处理方法，图7是根据本发明实施例的数码卡的处理方法的流程图，如图7所示，该流程包括如下步骤：
步骤S702，检测用于指示欲取出安全数码SD卡的指示信号；
步骤S704，在指示信号触发下，卸载SD卡。
通过上述步骤，在检测到想要取出SD卡时，首先卸载SD卡，相比于相关技术中，直接通过热插拔取下SD卡导致SD卡容易损坏和数据容易丢失，解决了相关技术中通过热插拔去处SD卡会对SD卡或SD卡中的文件造成损害的问题。进而实现了可以自动卸载SD卡并自动弹出，既保护了SD卡及其中的数据，也使用户的操作方便简捷的效果。
在一个可选实施例中，卸载SD卡之后，弹出SD卡。
在确定该SD卡正在进行读写操作时，在一个可选实施例中，首先停止SD卡的读写操作，并保存当前数据。在对SD卡进行卸载。
针对相关技术中存在的上述问题，下面结合具体的可选实施例进行说明，在下述可选实施例中结合了上述可选实施例及其可选实施方式。
图8是根据本发明实施例的数码卡的处理方法的流程图(一)，如图8所示，该流程包括如下步骤：
步骤S802，判断是否检测到用户取卡动作，在判断结果为是的情况下，执行步骤S804；
步骤S804，卸载SD卡；
步骤S806，弹出SD卡。
本可选实施例的目的是提供一种SD卡自动卸载自动弹出的方法和装置，当检测到用户准备取出SD卡时，可以实现SD卡自动卸载，然后自动弹出，从而有效地保护了SD卡及其中的数据。
相应地，本可选实施例还提供了一种电子装置，包括：
1)检测模块(相当于上述检测模块22)，设置为检测用户是否有取出SD卡的动作，并输出指示信号给控制模块；
2)控制模块(相当于上述控制模块24)，设置为收到检测模块的指示信号后，执行SD卡的自动卸载操作，并在卸载完成后使能电源模块；
3)电源模块(相当于上述电源模块262)，设置为给弹出模块提供电能；
4)弹出模块(相当于上述弹出模块26)，设置为将电能转换为机械能，自动弹出SD卡，并在SD卡弹出后输出第二指示信号给控制模块。
图9是根据本发明实施例的系统框图，如图9所示，该系统由检测模块，控制模块，电源模块和弹出模块组成。
本可选实施例中检测模块设置为检测用户是否有取卡的动作。具体实现中，检测模块通过按键或者触屏等方式感知用户的动作来判断用户是否取卡。图10是根据本发明实施例的一种实现装置检测模块的结构示意图，如图10所示，1、按键，2、取卡针，3、卡托。当用户通过卡托的小孔用取卡针按压薄膜按键，就会产生一个高电平转化为低电平的中断信号给控制器。
可选地，按键不仅可以如图10放在手机内部通过取卡针操作，也可以如同电源键一样放在手机外表面由用户直接操作。按键不仅可以是实体按键，也可以是虚拟按键。
本可选实施例中控制模块可以是手机内部集成的应用处理器。控制模块设置为卸载SD卡，并使能电源模块给弹出模块供电或断电。当控制模块收到检测模块发过来的用户取SD卡信号后，首先执行卸载SD卡操作，当卸载完成后，就发出控制信号给电源，使其给弹出模块供电；当控制模块收到弹出模块发过来的SD卡已弹出信号，就发出控制信号给电源，使其停止给弹出模块供电。
当控制模块执行SD卡卸载操作时，首先判断SD卡是否正在进行读写操作，如果正在进行读写操作的话，停止对SD卡的读写操作并保存当前数据，然后进行SD卡的 卸载流程并按时序给SD卡下电；如果没有进行读写操作，就直接进行SD卡的卸载流程并按时序给SD卡下电。
控制模块流程图可以参照图11。其中，检测模块中断信号是指检测模块已检测到用户有取SD卡动作后给控制模块发出的指示信号；弹出模块中断信号是指弹出模块已检测到SD卡已弹出给控制模块发出的第二指示信号。如图11所示，该流程包括如下步骤：
步骤S1102，判断是否有检测模块中断信号，在判断结果为是的情况下，执行步骤S1104；
步骤S1104，判断SD卡是否在读写，在判断结果是的情况下，执行步骤SS1106，在判断结果为否的情况下，执行步骤S1108；
步骤S1106，停止对SD卡的读写操作；
步骤S1108，卸载SD卡；
步骤S1110，使能电源为电磁铁供电；
步骤S1112，判断是否有弹出模块的中断信号，在判断结果为是的情况下，执行步骤S1114；
步骤S1114，使能电源停止给电磁铁供电。
本可选实施例中电源可以是手机内部集成的电源管理芯片，也可以是分立的开关电源或线性电源，其输入来自与手机的电池或上一级电源。当收到控制模块发出的信号后，输出或停止输出电流给弹出模块。
弹出模块是本可选实施例的核心，当有电流时，可以弹出SD卡；当没有电流时，停止弹出。同时，还可以检测SD卡是否弹出，当SD卡已弹出时发出中断信号给控制模块。图12是本发明一种实现装置弹出模块的结构示意图。参照图12，弹出模块由卡托、恢复弹簧、卡座、锁卡连杆、衔铁、电磁铁、释放弹簧和弹簧复位开关等组成。
其中，卡托设置为放置SD卡，其内部形状与SD卡契合；而外部形状中左侧有一内凹，可以和锁卡连杆配合，当卡托插入卡座后，被锁卡连杆锁住，使其不会掉落；而顶端右侧有一小孔，方便取卡针插入，对按键进行按压。
锁卡连杆由一个竖杆和横杆连接而成，竖杆中间凸起部分为半月形且与恢复弹簧相连，横杆与衔铁相连。
卡座固定在手机主板上，内有弹簧复位开关和控制器相连。当卡托插入后，开关被卡托压住，进入闭合状态，发送卡托插入信号给控制器；当卡托弹出后，开关被弹簧复位，进入断开状态，发送卡托弹出信号给控制器(即SD卡已弹出中断信号)。
电磁铁和衔铁配合使用，当电磁贴通电后，会产生磁场，处于磁场中的衔铁受到磁力影响，会向下运动一定的行程。
恢复弹簧一端连接锁卡连杆的竖杆，一端连接卡座。当其处于自由状态时，锁卡连杆可以锁住卡托；当其处于压缩状态时，锁卡连杆无法锁住卡托。
释放弹簧一端连接卡座，另一端与卡托接触(并未连接)。当卡托插入时，其处于压缩状态；当锁卡连杆无法锁住卡托时，弹力可将卡托弹出一定行程，此时处于自由状态。
当用户插入卡托时，用力按压卡托，卡托左侧的中间凹下部分正好被锁卡连杆竖杆的凸起部分锁住，此时释放弹簧处于压缩状态，而恢复弹簧处于自由状态，电磁铁未通电，衔铁处于水平位置。卡托压住弹簧复位开关，使其闭合，通知控制器卡托插入。此时，弹出模块各器件结构的位置可以参照图12-A。1、按键，2、取卡针，3、卡托，4、恢复弹簧，5、卡座，6、锁卡连杆，7、衔铁，8、电磁铁，9、释放弹簧，10、弹簧复位开关。
当电磁铁通电后，衔铁向下运动。锁卡连杆的横杆也被带动向下运动，竖杆受牵引向左运动。当竖杆向左运动到一定行程时，卡托便不再被锁住，释放弹簧的弹力便将卡托弹出到一定行程，那么卡托便可以用手取出。此时，恢复弹簧处于压缩状态，释放弹簧处于自动状态。此时，弹出模块各器件结构的位置可以参照图12-B。
当卡托弹出后，弹簧复位开关断开，通知控制器卡托已弹出。控制器便使能电源断开输出。电磁点断电后，磁场消失，衔铁不再受向下的磁力。此时，当用户把卡托取出后，恢复弹簧的弹力便将锁卡连杆恢复到初始位置。此时，弹出模块各器件结构的位置可以参照图12-C。
弹出模块流程图可以参照图13，如图13所示，该流程包括如下步骤：
步骤S1302，卡托插入；
步骤S1304，恢复弹簧自由状态，释放弹簧压缩状态，弹簧复位开关闭合状态；
步骤S1306，判断是否检测到按键被按下，在判断结果为是的情况下，执行步骤S1308；
步骤S1308，控制模块执行SD卡卸载流程；
步骤S1310，电源模块输出电流给电磁铁；
步骤S1312，电磁铁产生磁场磁力吸引衔铁向下移动；
步骤S1314，锁卡连杆竖杆向左移动；
步骤S1316，释放弹簧弹出卡托；
步骤S1318，弹簧复位开关输出断开信号；
步骤S1320，控制模块使能电源停止输出电流；
步骤S1322，电磁铁不产生磁场，衔铁不再受力；
步骤S1324，恢复弹簧使锁卡连杆复位。
