步骤S1、在移动终端开机时，控制可控开关300闭合（参考图1），关闭暂存模块150，然后由卡初始化模块110对microSD卡200进行初始化，使microSD卡能够正常工作。
步骤S2、启动超时时间为10秒的定时器130。
等待条件产生，在图3中的一个“等待条件产生”的框，其为等待条件
“定时器130超时”或“检测到主控制器100有数据发向microSD卡200”两个条件产生。
当定时器130超时时，执行步骤S3。
步骤S3、控制开关300断开；并启动暂存模块150将主控制器100最近一次发向microSD卡的数据保存下来；关闭定时器130。
当检测到主控制器100有数据发向microSD卡200时，执行步骤S4；
步骤S4、判断开关300是否闭合，若为是则执行步骤S5，若为否则执行步骤S6。
步骤S5、复位定时器130。
步骤S6、控制开关300闭合，关闭暂存模块150，然后由卡初始化模块110对microSD卡200进行初始化，重发暂存模块150中保存的数据给microSD卡200；之后执行步骤S7；
步骤S7、启动定时器130。
由上可见，本发明提供一种移动终端microSD卡的省电控制方法，通过检测microSD卡是否处于闲置状态，并将microSD卡闲置状态下的供电断开以节省移动终端的电能，能有效地节约移动终端的电能，延长电池的使用时间，为用户提供了方便。
基于上述实施例，本发明还提供了一种移动终端microSD卡的控制系统，如图4所示，所述系统包括：
第一检测与控制模块410，用于控制移动终端检测主控制器与microSD卡之间是否连续超过一预定时间无数据通信，如果是则控制停止对microSD卡供电；具体如上所述。
第二检测与控制模块420，用于在主控制器对microSD卡停止供电时，如果检测到主控制器向microSD卡发送数据则记录该需发送的数据，并重新控制主控制器启动对microSD卡供电，初始化microSD卡，再将先前保存的所述需发送的数据再次向microSD卡发送；具体如上所述。
进一步地，所述的移动终端microSD卡的控制系统，其中，还包括：
卡初始化模块110，用于在移动终端开机时，将主控制器的供电端与microSD卡相连接，并初始化microSD卡使microSD卡能够正常工作；具体如上所述。
所述的移动终端microSD卡的控制系统，其中，第一检测与控制模块410包括：
第一检测单元，用于检测主控制器是否与microSD卡进行数据通信；
第二检测单元，用于检测主控制器没有与microSD卡进行数据通信，再次检测主控制器与microSD卡之间是否连续超过一预定时间无数据通信；
控制单元，用于如果当前microSD卡的VDD管脚与主控制器连接，且在所述预定时间内主控制器未与microSD卡发生数据通信，则控制断开microSD卡的VDD脚与主控制器的连接。
综上所述，本发明所提供的移动终端及其microSD卡的控制方法及系统，由于采用了通过检测主控制器与microSD卡之间是否连续10秒钟无数据通信，如果为是则认为microSD卡闲置，然后停止对microSD卡供电以节省电能；在主控制器对microSD卡停止供电的情况下，如果检测到主控制器向microSD卡发送数据则记录该数据，然后主控制器启动对microSD卡供电，初始化microSD卡，再将先前保存的数据再次向microSD卡发送。通过本发明方法在维持现在microSD卡的功能的基础上，通过检测microSD卡是否闲置来决定是否对microSD卡供电，以节省移动终端电池的电能，能有效地节约移动终端的电能，延长电池的使用时间，为用户提供了方便。
应当理解的是，本发明的应用不限于上述的举例，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，所有这些改进和变换都应属于本发明所附权利要求的保护范围。
