Description

移动终端及其自动关机方法、 装置和计算机存储介庸 技术领域
本发明涉及通信技术领域, 尤其涉及一种移动终端及其自动关机方法、 装置和计算机存储介质。 背景技术
随着信息技术的迅速发展, 多媒体产品和人们的生活联系越来越紧密, 多媒体产品已经成为日常生活中必不可少的一部分。 随着多媒体产品应用 率的提高, 多媒体产品在各个环境中的突发事件也越来越多, 其中以产品 跌落而产生故障的事件最为常见。
目前对传统多媒体产品,如动态影像专家压缩标准音频层面 3 ( Moving Picture Experts Group Audio Layer III, 简称 MP3 )播放器、 动态影像专家压 缩标准音频层面 4( Moving Picture Experts Group Audio Layer IV ,简称 MP4 ) 播放器等进行跌落保护的方法, 现有保护方案主要从原材料的选用以及工 程力学结构设计上等方面进行考虑以保护完善。 比如在多媒体产品跌落时, 通过将多媒体产品的外壳解体以分散多媒体产品受力, 从而降低多媒体产 品受到的外力冲击破坏影响。 另外, 有的从硬件材料的材质选用上考虑, 对多媒体产品跌落后的关键受力部位, 采用合适的软性受力緩冲材料以减 緩跌落时的冲击力。 但是, 这些方法都有一个主要缺点: 多媒体产品在跌 落过程中, 如果处于开机运行状态, 那么多媒体产品的软件和硬件都会一 直处于运行状态, 软件程序运行时会对只读存储器 (ROM-Read Only Memory, ROM ) /随机存者器 ( Random Access Memory, RAM ) 的输入输 出 ( Input/Output, I/O )端口进行访问控制。 当多媒体产品跌落发生受到严 重外力冲击碰撞时, 可能会对正在访问的输入输出控制设备及程序产生错 误, 导致硬件芯片损坏或者软件死机, 甚至因启动 (Boot ) 固化引导程序 的执行被破坏后, 而导致系统软件即使重启后也不可恢复。 另外, 电子元 器件在带电运行时发生严重摔落碰撞后, 可能会使电子元器件直接被损坏, 而无法再继续工作。 发明内容
有鉴于此, 本发明实施例期望提供一种移动终端及其自动关机方法、 装置和计算机存储介质, 旨在通过重力加速度的测量, 从而在移动终端跌 落时自动切断电源达到保护移动终端的目的。
为了达到上述目的, 本发明实施例的技术方案是这样实现的: 本发明实施例提供了一种移动终端自动关机方法, 所述方法包括以下 步骤:
接收重力传感器实时侦测到的移动终端在竖直方向上的瞬时加速度 值;
判断接收到的所述瞬间加速度值是否大于或等于预设加速度阈值; 若所述瞬间加速度值大于或等于所述预设加速度阈值, 则向硬关机电 路模块发送关机指令以切断所述移动终端的电源。

下面结合附图及具体实施例就本发明的技术方案做进一步的说明。 应 当理解, 此处所描述的具体实施例仅仅用以解释本发明, 并不用于限定本 发明。
本发明提出一种移动终端自动关机方法。
参照图 1,图 1为本发明移动终端自动关机方法的第一实施例的流程示 意图。
本发明提出移动终端自动关机方法的第一实施例。 本实施例中, 移动 终端自动关机方法包括以下步骤:
步骤 S10,接收重力传感器实时侦测到的移动终端在竖直方向上的瞬时 力口速度值;
本发明所提到的移动终端可以为手机、 MP3、 MP4、 遥控器、 电脑等, 本发明对此不作限定。 为了更好说明本移动终端自动关机方法的原理, 本 实施例以手机为例进行具体说明。
步骤 S20,判断接收到的所述瞬间加速度值是否大于或等于预设加速度 阈值; 若所述瞬间加速度值大于或等于所述预设加速度阈值, 则执行步骤 S30; 若所述瞬间加速度值小于所述预设加速度阈值, 则执行步骤 S40。
具体地, 预设加速度阈值可以通过提前预置, 也可通用用户手动输入。 预设加速度阈值理论上优选手机所处的当地的重力加速度值。 因各地区的 重力加速度值略有差别, 可以在手机内设置内置模块, 用户输入手机所在 地区然后在预置数据库中查询地区所对应的重力加速度值。 或者手机通过 GPRS定位然后网络获取到地区所对应的重力加速度值。当接收到的瞬间加 速度值是否大于或等于预设加速度阈值, 说明此时手机处于跌落状态。
另外, 需要说明的是, 当手机处于跌落状态时, 测得手机的瞬间加速 度值理论上应等于当地的重力加速度值, 但因测量误差或手机处于不同地 方重力加速度值的细微差异性, 因此, 将瞬间加速度值大于或等于重力加 速度值作为判定是否跌落的条件。 也可经过重力传感器的多次测量后, 更 新预设加速度阈值, 从而使判定手机是否处于跌落状态过程更加准确。 步骤 S30, 向硬关机电路模块发送关机指令以切断移动终端的电源。 步骤 S40, 控制移动终端正常运行。
在瞬间加速度值小于所述预设加速度阈值时, 也可通过手机的显示装 置显示手机从刚跌落瞬间到接触地面之间的时间, 即手机进行自由落体运 动的时间。
硬关机电路模块可以实现手机的瞬间硬掉电关机, 达到与拔掉手机电 池一样的效果。 本实施例中, 硬关机电路模块与手机的电源模块电连接, 达到直接控制切断电源的目的。 硬掉电关机不同于按下手机电源键的软关 机, 软关机耗费的时间长, 当发出软关机指令后, 可能手机还未完全关机 而手机已经跌落到地面, 这样, 就无法达到保护手机的目的。
本实施例提出的移动终端自动关机方法, 通过接收重力传感器实时侦 测到的移动终端在竖直方向上的瞬时加速度值, 然后判断接收到的瞬间加 速度值是否大于或等于预设加速度阈值, 当判断出瞬间加速度值大于或等 于预设加速度阈值时, 说明手机处于跌落状态, 此时, 本实施例设置专用 的硬关机电路模块, 向硬关机电路模块发送关机指令以切断移动终端的电 源, 达到在关机时机点的瞬间 (毫秒 /微妙级别时间内)切断移动终端电源 的目的, 通过切断电源, 保护了手机的硬件以及软件。 另外, 当手机开机 运行时, 如果手机跌落进水时, 开机运行加速元器件损坏速度, 而本移动 终端自动关机方法, 在手机跌落进水之前已切断电源, 从而将手机可能因 进水而产生的破坏降到最低。
参照图 2,图 2为本发明移动终端自动关机方法的第二实施例的流程示 意图。
本发明提出移动终端自动关机方法的第二实施例。 本实施例中与上述 第一实施例不同的是, 在步骤 S20之后, 当判断瞬间加速度值大于或等于 所述预设加速度阈值, 则执行步骤 S50; 执行步骤 S50后, 继续执行步骤 S60。
步骤 S50,接收速度传感器实时侦测到的移动终端在竖直方向上的瞬时 速度值;
步骤 S60, 当接收到的所述瞬间速度值大于或等于预设速度阈值时, 向 所述硬关机电路模块发送关机指令以切断移动终端的电源。
当判断出瞬间加速度值 大于或等于预设加速度阈值时, 说明手机处于 跌落状态, 此时, 实时检测移动终端在竖直方向上的瞬时速度值, 如果瞬 间速度值大于或等于预设速度阈值时, 则向硬关机电路模块发送关机指令 以切断移动终端的电源。 如可设置当 v=4.5m/s 时, 说明手机已跌落一定距 离, 此时, 向硬关机电路模块发送关机指令以切断移动终端的电源。
本实施例中, 预设速度阈值可手机提前预置, 也可用户根据自己的使 用习惯合理地设置预设速度阈值。
本实施例提出的移动终端自动关机方法, 通过设置预设速度阈值, 只 有在速度传感器实时侦测到的移动终端在竖直方向上的瞬时速度值大于或 等于预设速度阈值时, 才会向硬关机电路模块发送关机指令以切断移动终 端的电源, 从而避免了一些场景下的误判而引起的不必要的关机。 如用户 往桌上或床上轻放手机, 这个距离是比较短的, 因此, 手机不会产生一个 很大的瞬间速度值。 即本移动终端自动关机方法设置预设速度阈值是一个 关机的条件, 只有达到这个关机条件时, 才会控制移动终端的电源切断。
参照图 3,图 3为本发明移动终端自动关机方法的第三实施例的流程示 意图。
本发明提出移动终端自动关机方法的第三实施例。 本实施例中与上述 第二实施例不同的是, 在步骤 S50之后, 执行步骤 S70; 执行步骤 S70后 继续执行步骤 S80。
步骤 S70,根据接收到的所述瞬时速度值计算所述移动终端在竖直方向 上的跌落距离参数或跌落时间参数;
步骤 S80, 当所述跌落距离参数大于或等于预设距离阈值,或所述跌落 时间参数大于或等于预设时间阈值时, 向所述硬关机电路模块发送关机指 令以切断移动终端的电源。
在手机跌落时做自由落体运动。 根据物理学公式:
( 1 ) h = -gt2 ;
2
( 2 ) v = 。 其中, V为手机跌落时的实时测量的瞬时速度值, g为重力加速度, t为 手机跌落时间参数, A手机距离时间参数。
将获取到的瞬时速度值代入公式(1 ) 和(2 ) 中可以得出跌落距离参 数和跌落时间参数, 用户可根据自己习惯预置预设距离阈值和预设时间阈 值。
跌落距离参数和跌落时间参数即为手机切断电源的关机条件。 如手机 从高为 2米处跌落下来, 而用户设置的跌落距离参数为 1米, 当手机跌落 至 1 米时, 速度传感器获取到实时瞬时速度值, 然后计算出对应的跌落距 离参数为 1米, 这时, 控制关机。 而如果手机从小于 1米的高度跌落下来, 因没有达到预设距离阈值, 手机保持正常运行状态。
参照图 4,图 4为本发明移动终端自动关机方法的第四实施例的流程示 意图。
本发明提出移动终端自动关机方法的第四实施例。 本实施例中与上述 第三实施例不同的是, 在步骤 S80之后, 执行步骤 S90; 执行步骤 S90后 继续执行步骤 S91 和步骤 S92。
步骤 S90, 存储所述移动终端在落地瞬间时竖直方向上的瞬间速度值; 步骤 S91,根据所述瞬间速度值,计算并存储所述移动终端在落地瞬间 时竖直方向上的跌落距离参数和跌落时间参数; 步骤 S92,根据存储的在落地瞬间时所述瞬间速度值、跌落距离参数和 跌落时间参数分别更新所述预设速度阈值、 预设距离阈值和预设时间阈值。
手机落地瞬间, 可以通过存储移动终端在落地瞬间时竖直方向上的瞬 间速度值, 并将瞬间速度值代入公式(1 )和(2 ) 中, 可以得出手机在落 地瞬间时竖直方向上的跌落距离参数和跌落时间参数。 当手机多次跌落后, 可以得到多个跌落事件时手机的瞬间速度值、 跌落距离参数和跌落时间参 数, 可根据多个瞬间速度值、 跌落距离参数和跌落时间参数分别设置预设 速度阈值、 预设距离阈值和预设时间阈值。 如可将手机存储的多个在落地 瞬间时瞬间速度值、 跌落距离参数和跌落时间参数分别取平均值, 然后, 预设速度阈值、 预设距离阈值和预设时间阈值分别小于该平均值一定范围。
本实施例提出的移动终端自动关机方法, 通过存储所述移动终端在落 地瞬间时竖直方向上的瞬间速度值, 并根据瞬间速度值, 计算并存储移动 终端在落地瞬间时竖直方向上的跌落距离参数和跌落时间参数, 再根据存 储的在落地瞬间时所述瞬间速度值、 跌落距离参数和跌落时间参数分别更 新所述预设速度阈值、 预设距离阈值和预设时间阈值, 从而使本移动终端 自动关机方法中预设速度阈值、 预设距离阈值和预设时间阈值的设定更加 符合不同用户的使用习惯, 更加人性化。
本发明进一步还提出一种移动终端自动关机装置。
参照图 5,图 5为本发明移动终端自动关机装置的第一实施例的结构示 意图。
本实施例中提出移动终端自动关机装置的第一实施例。 本实施例中, 移动终端自动关机装置包括:
接收模块 10, 配置为接收重力传感器实时侦测到的移动终端在竖直方 向上的瞬时加速度值;
判断模块 20, 配置为判断接收到的所述瞬间加速度值是否大于或等于 预设加速度阈值;
控制模块 30, 配置为当所述瞬间加速度值大于或等于所述预设加速度 阈值时, 向硬关机电路模块发送关机指令以切断所述移动终端的电源。
本发明所提到的移动终端可以为手机、 MP3、 MP4、 遥控器、 电脑等, 本发明对此不作限定。 为了更好说明本移动终端自动关机装置的原理, 本 实施例以手机为例进行具体说明。
具体地, 预设加速度阈值可以通过提前预置, 也可通用用户手动输入。 预设加速度阈值优选为手机所处的当地的重力加速度值。 因各地区的重力 加速度值略有差别, 可以在手机内设置内置模块, 用户输入手机所在地区 然后在预置数据库中查询地区所对应的重力加速度值。或者手机通过 GPRS 定位然后网络获取到地区所对应的重力加速度值。 当接收到的瞬间加速度 值是否大于或等于预设加速度阈值, 说明此时手机处于跌落状态。
在瞬间加速度值小于所述预设加速度阈值时, 也可通过手机的显示装 置显示手机从刚跌落瞬间到接触地面之间的时间, 即手机进行自由落体运 动的时间。
硬关机电路模块可以实现手机的瞬间硬掉电关机, 达到与拔掉手机电 池一样的效果。 本实施例中, 硬关机电路模块与手机的电源模块电连接, 达到直接控制切断电源的目的。 硬掉电关机不同于按下手机电源键的软关 机, 软关机耗费的时间长, 当发出软关机指令后, 可能手机还未完全关机 而手机已经跌落到地面, 这样, 就无法达到保护手机的目的。
本实施例提出的移动终端自动关机装置, 通过接收模块 10接收重力传 感器实时侦测到的移动终端在竖直方向上的瞬时加速度值, 判断模块 20判 断接收到的瞬间加速度值是否大于或等于预设加速度阈值, 当判断出瞬间 加速度值大于或等于预设加速度阈值时, 说明移动终端处于跌落状态, 此 时控制模块 30向硬关机电路模块发送关机指令以切断移动终端的电源, 达 到在关机时机点的瞬间(毫秒 /微妙级别时间内 )切断移动终端电源的目的, 通过切断电源, 保护了手机的硬件以及软件。 另外, 当手机开机运行时, 如果手机跌落进水时, 开机运行加速元器件损坏速度, 而本移动终端自动 关机装置, 在手机跌落进水之前已切断电源, 从而将手机可能因进水而产 生的破坏降到最低。
进一步地, 接收模块 10还配置为当所述瞬间加速度值大于或等于所述 预设加速度阈值, 接收速度传感器实时侦测到的所述移动终端在竖直方向 上的瞬时速度值;
控制模块 30还配置为当接收到的所述瞬间速度值大于或等于预设速度 阈值时, 向所述硬关机电路模块发送关机指令以切断所述移动终端的电源。
当判断出瞬间加速度值 大于或等于预设加速度阈值时, 说明手机处于 跌落状态, 此时, 通过速度传感器实时检测移动终端在竖直方向上的瞬时 速度值, 如果瞬间速度值大于或等于预设速度阈值时, 控制模块 30向硬关 机电路模块发送关机指令以切断移动终端的电源。如可设置当 v=4.5m/s时, 说明手机已跌落一定距离, 此时, 向硬关机电路模块发送关机指令以切断 移动终端的电源。
本实施例中, 预设速度阈值可手机提前预置, 也可用户根据自己的使 用习惯合理地设置预设速度阈值。
本实施例提出的移动终端自动关机装置, 通过设置预设速度阈值, 只 有在速度传感器实时侦测到的移动终端在竖直方向上的瞬时速度值大于或 等于预设速度阈值时, 才会向硬关机电路模块发送关机指令以切断移动终 端的电源, 从而避免了一些场景下的误判而引起的不必要的关机。 如用户 往桌上或床上轻放手机, 这个距离是比较短的, 因此, 手机不会产生一个 很大的瞬间速度值。 即设置预设速度阈值是一个关机的条件, 只有达到这 个关机条件时, 才会控制移动终端的电源切断。 参照图 6,图 6为本发明移动终端自动关机装置的第二实施例的结构示 意图。
本实用新型提出移动终端自动关机装置的第二实施例。 本实施例中与 上述实施例不同的是, 移动终端自动关机装置还包括:
第一计算模块 40, 配置为根据接收到的所述瞬时速度值计算所述移动 终端在竖直方向上的跌落距离参数或跌落时间参数;
控制模块 30,还配置为当所述跌落距离参数大于或等于预设距离阈值, 或所述跌落时间参数大于或等于预设时间阈值时, 向所述硬关机电路模块 发送关机指令以切断所述移动终端的电源。
在手机跌落时做自由落体运动。 根据物理学公式:
( 1 ) h = -gt2
2
( 2 ) v = gt。
V为手机跌落时的实时测量的瞬时速度值, g为重力加速度, t为手机 跌落时间参数, A手机距离时间参数。
通过获取到的瞬时速度值代入公式 (1 )和(2 ) 中可以得出跌落距离 参数和跌落时间参数, 用户可根据自己习惯预置预设距离阈值和预设时间 阈值。
跌落距离参数和跌落时间参数即为手机切断电源的关机条件。 如手机 从高为 2米处跌落下来, 而用户设置的跌落距离参数为 1米, 当手机跌落 至 1 米时, 速度传感器获取到实时瞬时速度值, 然后计算出对应的跌落距 离参数为 1米, 这时, 控制关机。 而如果手机从小于 1米的高度跌落下来, 因没有达到预设距离阈值, 手机保持正常运行状态。
参照图 7,图 7为本发明移动终端自动关机装置的第三实施例的结构示 意图。
本实用新型提出移动终端自动关机装置的第三实施例。 本实施例中与 上述实施例不同的是, 移动终端自动关机装置还包括:
存储模块 50, 配置为存储所述移动终端在落地瞬间时竖直方向上的瞬 间速度值;
第二计算模块 60, 配置为根据所述瞬间速度值, 计算并存储所述移动 终端在落地瞬间时竖直方向上的跌落距离参数和跌落时间参数;
更新模块 70, 配置为根据存储的在落地瞬间时所述瞬间速度值、 跌落 距离参数和跌落时间参数分别更新所述预设速度阈值、 预设距离阈值和预 设时间阈值。
需要说明的是, 此时, 需设置单独的电源模块对移动终端自动关机装 置以及重力传感器、 速度传感器进行供电。 此电源模块独立于与前面所述 的手机的电源。
手机落地瞬间, 可以通过获取并存储移动终端在落地瞬间时竖直方向 上的瞬间速度值, 并将瞬间速度值代入公式(1 )和(2 ) 中, 可以得出手 机在落地瞬间时竖直方向上的跌落距离参数和跌落时间参数。 当手机多次 跌落后, 可以得到多个跌落事件时手机的瞬间速度值、 跌落距离参数和跌 落时间参数, 可根据多个瞬间速度值、 跌落距离参数和跌落时间参数分别 设置预设速度阈值、 预设距离阈值和预设时间阈值。 如可将手机存储的多 个在落地瞬间时瞬间速度值、 跌落距离参数和跌落时间参数分别取平均值, 然后, 预设速度阈值、 预设距离阈值和预设时间阈值分别小于该平均值一 定范围。
本实施例提出的移动终端自动关机装置, 通过存储模块 50接收并存储 所述移动终端在落地瞬间时竖直方向上的瞬间速度值, 第二计算模块 60根 据瞬间速度值, 计算并存储移动终端在落地瞬间时竖直方向上的跌落距离 参数和跌落时间参数, 更新模块 70根据存储的在落地瞬间时所述瞬间速度 值、 跌落距离参数和跌落时间参数分别更新所述预设速度阈值、 预设距离 阈值和预设时间阈值, 从而使本移动终端自动关机装置中预设速度阈值、 预设距离阈值和预设时间阈值的设定更加符合不同用户的使用习惯, 更加 人性化。
实际应用中, 所述自动关机装置可设置于移动终端中; 上述接收模块
10、 判断模块 20、 控制模块 30、 第一计算模块 40、 第二计算模块 60、 更 新模块 70均可由移动终端的中央处理器 ( CPU, Central Processing Unit )、 数字信号处理器( DSP, Digital Signal Processor )或可编程门阵列 ( FPGA, Field Programmable Gate Array ) 实现; 存储模块 50可由移动终端中的存储 介质实现, 比如: 各种类型的存储器。
