Description

数据采集方法及装置、 移动终端 本申请要求于 2012年 02月 24日提交中国专利局、 申请号为 201210044164. 5、发明名称 为 "数据采集方法及装置、 移动终端" 的中国专利申请的优先权, 其全部内容通过引用结合 在本申请中。 技术领域
本发明涉及通讯领域, 尤其涉及一种适用于包括多个数据采集单元的装置中的数据采集 方法及装置、 移动终端。 背景技术
在已知的移动终端中, 一个移动终端通常采用多个不同的数据采集单元, 比如传感器, 来获取外部的各种环境数据, 从而保证运行在这个移动终端上的应用程序可以利用这些环境 数据来实现某些功能。 以智能手机为例, 通常都包括用于采集重力加速度数据的重力加速度 传感器, 以便实现例如手机横竖屏切换、 来电时翻动机身静音之类的功能; 还可以包括用于 采集方向数据的电子罗盘传感器, 以便实现指南针之类的功能; 还可以包括用于感应人脸远 近信息的红外线传感器, 以便实现打电话过程中屏幕及触摸屏自动关闭之类的功能等等。
对于实现某一项功能的应用程序来说, 可能需要同时使用多个传感器采集的数据来协作 实现对应的功能。 比如, 为实现在用户打电话的时候关闭屏幕显示以及触摸屏的功能, 以防 止人脸接触触摸屏发生误触情况的应用程序, 不仅需要红外线传感器采集的人脸远近信息的 数据, 还需要使用重力加速度传感器采集的重力加速度数据。 也即只有在红外线传感器采集 的人脸远近信息的数据代表用户的脸部接近了屏幕, 同时重力加速度传感器采集的重力加速 度数据代表手机是竖立形态时, 才会触发关闭屏幕显示以及触摸屏的功能。
为了满足这类型应用程序对多个传感器采集的数据的需求, 现有技术中存在一种数据采 集方法, 该方法主要包括: 各个传感器按照各自的采集频率采集数据; 然后各个传感器判断 本次采集的数据与前次采集的数据之差是否大于预定阀值, 如果是, 则上报给中间层; 中间 层从每个传感器上报的数据中挑选属于同一时刻或者相近时刻的一组或者多组数据提供给应 用程序使用。
但是, 当一个应用程序在某一时刻需要多个传感器采集的数据时, 采用上述数据采集方 法可能就不能及时获得这一时刻每个传感器采集的实时的、 准确的数据, 而是获得了各个传 感器在这一时刻的相近时刻的数据。 这种数据不能满足一些对数据精确性要求较高的应用程 序的需求, 例如用于判断手机姿态以及运动轨迹的应用程序, 需要在同一时间获取重力加速 度传感器、 电子罗盘传感器和陀螺仪传感器的数据, 以便计算手机的姿态、 方位和运动速度 等信息, 如果三个传感器的数据采集时间点并不是精确的同一时刻, 则会导致该应用程序的 计算出现误差。 发明内容

为了更清楚地说明本发明实施例中的技术方案, 下面将对实施例描述中所需要使用的附 图作简单地介绍, 显而易见地, 下面描述中的附图仅仅是本发明的一些实施例, 对于本领域 普通技术人员来讲, 在不付出创造性劳动的前提下, 还可以根据这些附图获得其他的附图。

图 4是本发明实施例三提供的同步采集频率选取模块的结构方框图。 具体实施方式
下面将结合本发明实施例中的附图, 对本发明实施例中的技术方案进行清楚、 完整地描 述, 显然, 所描述的实施例仅仅是本发明一部分实施例, 而不是全部的实施例。 基于本发明 中的实施例, 本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例, 都属于本发明保护的范围。 实施例一
请参考图 1, 其示出了本发明实施例一提供的数据采集方法的方法流程图。 该数据采集 方法可以用于包括多个数据采集单元的装置中。 所述装置可以是诸如个人电脑、 服务器之类 的固定终端, 也可以是诸如笔记本、 平板电脑和手机之类的移动终端。 该数据采集方法具体 包括:
步骤 102, 至少两个数据采集单元根据一采集起始时刻同时以各自的采集频率采集初步 数据;
本文中的数据采集单元主要指各种传感器, 显然在其它实施例中, 数据采集单元也可以 是按照一定频率采集数据的其它模块。 本实施例中也主要以数据采集单元为传感器为例来进 行详细描述, 但不构成对其的限定。
根据前述内容可知, 有时一个应用程序会同时需要多个传感器在相同时刻采集的数据, 这多个传感器可能是一个终端内所有的传感器, 也可能是一个终端内所有的传感器中的一部 分, 这一部分传感器可以是两个、 三个或者更多个传感器。 为了能够采集到这至少两个传感 器在相同时刻采集的数据, 首先需要将这至少两个传感器的某个数据采集时刻都置为相同的 时刻。 通常情况下, 此处是将这至少两个传感器第一次数据采集的时刻置为相同的时刻, 也 即可以设置一个采集起始时刻, 然后这至少两个数据采集单元可以根据这个采集起始时刻同 时开始以各自的采集频率采集初步数据。
步骤 104, 根据一同步采集频率采集至少两个数据采集单元所采集的初步数据以得到同 步数据。 其中, 同步采集频率为该至少两个数据采集单元各自的采集频率的公约数频率。
在采集起始时刻之后, 可以根据一同步采集频率采集每个传感器所采集的初步数据, 此 处的同步采集频率可以为每个传感器各自的采集频率的公约数频率, 比如一个传感器的采集 频率为 100HZ, 另一个传感器的采集频率为 200HZ, 再一个传感器的采集频率为 50HZ, 则可 以采用的同步采集频率为 50HZ、 25HZ、 5HZ和 2HZ中的任意一个。 此时采集到的数据即为同 步数据, 而且每组同步数据中的各个传感器的数据都是在相同时刻的实时地、 精确地数据。 这些同步数据可以提供给应用程序使用。至于具体选取哪个公约数作为公约数频率的数值时, 本领域普通技术人员可以根据情况合理选择, 在此不再赘述。 优选的, 可以选择数值较大的 公约数作为公约数频率的数值。
综上所述, 本实施例一提供的数据采集方法通过调整至少两个数据采集单元的采集起始 时刻, 并同时按照同步采集频率从该至少两个数据采集单元采集的初步数据中抓取同步数据 的方式, 获得了各个数据采集单元的多组同步数据, 每组同步数据都是各个数据采集单元在 同一时刻的准确数据, 从而使得利用该多组同步数据的应用程序可以避免误差的产生。 实施例二
请参考图 2, 其示出了本发明实施例二提供的数据采集方法的方法流程图。 该数据采集 方法可以用于包括多个数据采集单元的装置中。 所述装置可以是诸如个人电脑、 服务器之类 的固定终端, 也可以是诸如笔记本、 平板电脑和手机之类的移动终端。 该数据采集方法具体 包括:
步骤 201, 在需要时注册多个数据采集单元中的至少两个数据采集单元作为待采集同步 数据的数据采集单元;
仍然以数据采集单元为传感器为例, 由于在一个终端中, 可能包括很多个传感器, 而应 用程序在某一时刻需要的可能只是其中一部分传感器在相同时刻的精确数据。 所以, 首先应 用程序在需要时可以注册所有传感器中的全部或者部分作为待采集同步数据的数据采集单 元。 换句话说, 被注册的待采集同步数据的数据采集单元是与获取应用程序需要的同步数据 相关的传感器, 对于终端中的其它传感器, 应用程序可以不注册。 比如, 应用程序是一个游 戏, 该游戏被用户运行时, 可以注册终端中的陀螺仪传感器、 重力加速度传感器和红外传感 器作为待采集同步数据的数据采集单元。
步骤 202, 将应用程序注册的数据采集单元的工作模式设置为第二工作模式; 由于传感器通常包括两种工作模式: 第一工作模式和第二工作模式, 其中第一工作模式 为: 传感器判断本次采集的数据与前次采集的数据之差是否大于预定阀值, 如果是, 则本次 采集的数据作为初步数据进行上报; 反之, 则不上报。 第二工作模式为: 传感器每次采集的 数据都作为初步数据进行上报。 终端中为了减少 CPU的工作量, 通常对各个传感器默认采用 第一工作模式。 而在本实施例中, 为了能够获取准确的数据, 在应用程序注册一部分传感器 之后, 需要将应用程序注册的该部分传感器的工作模式都设置为第二工作模式, 也即将被注 册的传感器的工作模式设置为每次采集的精确数据都作为初步数据上报的工作模式。
步骤 203, 根据至少两个数据采集单元的初始化时间长度获取采集起始时刻; 为了能够采集到被应用程序注册的至少两个传感器在相同时刻采集的数据, 需要先将这 至少两个传感器的某个数据采集时刻都置为相同的时刻。 通常情况下, 此处是将这至少两个 传感器第一次数据采集的时刻置为相同的时刻, 也即可以为被注册的传感器设置一个相同的 采集起始时刻, 以便这些传感器同时开始采集初步数据。 具体地讲:
第一, 获取每个传感器的初始化时间长度和初始化时间长度中最大的初始化时间长度。 其中, 初始化时间长度是指传感器从上电初始化开始到初始化完成并进行第一次数据采集的 这段时间。 对于不同的传感器, 该初始化时间长度可以互不相同。 第二, 在获得每个传感器的初始化时间长度后, 可以将未来的某一时刻作为采集起始时 刻, 该时刻通常不小于在当前时刻基础上向后延长步骤一中获取的最大的初始化时间长度得 到的时刻。也即,该采集起始时刻可以是(当前时刻 +最大的初始化时间长度)的时刻,或者(当 前时刻 +最大的初始化时间长度)之后的时刻。 比如, 一个传感器的初始化时间长度是 190ms, 而另外一个传感器的初始化时间长度是 120ms, 可以将 (当前时刻 +190 ms ) 或者 (当前时刻 +200ms ) 的时刻作为采集起始时刻。 在一个具体的实施例中, 可以有一个预定时间长度, 该 预定时间长度为大于等于 0的固定值, 然后终端可以在获取到最大的初始化时间长度之后, 自动将(当前时亥 lj+最大的初始化时间长度 +预定时间长度)所指示的时刻作为采集起始时刻。
步骤 204, 根据至少两个数据采集单元的采集频率选取同步采集频率;
此处的至少两个数据采集单元可以是指在步骤 201中被应用程序注册的传感器。 为了选 取同步采集频率, 需要获取这些被注册的传感器的采集频率, 有时还需要获取同步数据的需 求频率。
采集频率是传感器在第二工作模式下采集初步数据时的频率。 需要说明的是, 每个传感 器的采集频率可能不止一个, 此时可以获取该传感器的所有采集频率, 此处的采集频率既可 以指传感器的实际采集频率, 也可以指传感器上报初步数据的频率。
而同步数据的需求频率是同步数据被其它模块使用时所需要的频率, 该频率可以由其它 模块在同步数据采集之前指定。为了便于描述, 本文中将这些模块称之为同步数据使用模块, 该同步数据使用模块通常为应用程序。具体地讲, 当只有一个应用程序需要使用同步数据时, 需求频率即为该应用程序使用同步数据时需要的最低频率。 而当有若干个应用程序需要使用 同步数据时, 可以先获取各个应用程序需要使用同步数据时所需要的最低频率, 然后将各个 最低频率的最小公倍数的数值作为需求频率的数值, 比如, 一个应用程序最低需要按照 5HZ 的频率使用同步数据, 另一个应用程序最低需要按照 10HZ的频率使用同步数据, 再一个应用 程序最低需要按照 50HZ的频率使用同步数据, 则可以将 50HZ作为需求频率。
在获取每个传感器的采集频率之后, 可以获取每个传感器的采集频率的数值的所有公约 数, 比如一个传感器的采集频率为 400HZ, 另一个传感器的采集频率为 200HZ, 再一个传感器 的采集频率为 100HZ, 这些传感器的采集频率的数值的公约数为 100、 50、 25、 5、 2和 1等。 然后可以选取所有公约数中的任一个作为同步采集频率的数值。
但在较优的方案中, 在选取所有公约数中的一个为同步采集频率的数值时, 可以结合参 考同步数据的需求频率来进行更好地选取。 也即选取所有公约数中不小于需求频率的数值的 最小一个公约数作为同步采集频率的数值。 具体地讲, 可以筛选所有公约数中等于或者大于 需求频率的公约数, 然后选取筛选出的公约数中的最小的一个作为同步采集频率的值。 比如 同步数据的需求频率为 50HZ, 筛选出的公约数是 100和 50, 则可以选取其中较小的一个 50 为同步采集频率的值。
步骤 205,至少两个数据采集单元根据采集起始时刻同时开始以各自的采集频率采集初步 数据;
被应用程序注册的至少两个传感器可以根据步骤 203中获取的采集起始时刻同时开始以 各自的采集频率采集初步数据。 具体地讲:
第一, 在获取采集起始时刻之后, 可以根据采集起始时刻获取被应用程序注册的至少两 个传感器的初始化时刻, 获取的初始化时刻可以为在采集起始时刻基础上提前传感器各自的 初始化时间长度得到的时刻。 也即, 可以获取每个传感器的初始化时刻为 (采集起始时刻- 对应于该传感器的初始化时间长度)。 比如, 在采集起始时刻为 (当前时刻 +200ms ) 时, 可以 获取初始化时间长度是 190ms的传感器的初始化时刻为(当前时刻 +200mS-190ms ) = (当前时 亥 iJ+lOms ) ; 又可以获取初始化时间长度是 120ms 的传感器的初始化时刻为 (当前时刻 +200ms-120ms ) = (当前时刻 +80ms );
第二, 根据初始化时刻初始化被应用程序注册的至少两个传感器, 当被应用程序注册的 至少两个传感器在采集起始时刻同时完成初始化过程后, 将会自动以各自的采集频率采集初 步数据。 比如, 根据对各个传感器的初始化时刻可以启动相应的定时器, 使得在 (当前时刻 +10ms ) 时开始初始化第一个传感器, 在 (当前时刻 +80ms ) 时开始初始化第二个传感器。 最 终, 每个传感器都在采集起始时刻完成了初始化过程并开始第一次数据采集。需要说明的是, 由于传感器通常在终端开机时就已经运行, 此处的初始化一般都是将已经运行的相关传感器 进行重新初始化的一个过程。
还需要说明的是, 使每个传感器同时从该采集起始时刻开始以各自的采集频率采集初步 数据也可以采用其它方式。 比如, 有三个传感器, 第一个传感器一直保持运行, 第二个传感 器的初始化时间长度是 190ms, 而第三个传感器的初始化时间长度是 120ms。为了使这三个传 感器同时在采集起始时刻开始采集数据, 可以将第一个传感器采集数据过程中的某个数据采 集时刻 T为采集起始时刻, 然后可以启动相应的定时器提前在(T-190ms )的时刻开始初始化 第二个传感器, 并在 (T-120ms ) 的时刻开始初始化第三个传感器, 这样在 T时刻, 这三个传 感器也将同时开始以各自的采集频率采集初步数据。
步骤 206,按照同步采集频率采集至少两个数据采集单元所采集的初步数据以得到同步数 据。 在采集起始时刻之后, 可以按照步骤 204中选取的同步采集频率采集每个传感器采集的 初步数据以得到同步数据。 该同步数据可以提供给应用程序使用。 当然, 对应于步骤 201至 步骤 202, 应用程序在不需要同步数据时, 可以释放被注册的传感器; 被释放的传感器可以 从第二工作模式再变回第一工作模式等等。
综上所述, 本实施例二提供的数据采集方法通过调整至少两个数据采集单元的采集起始 时刻, 并同时按照同步采集频率从该至少两个数据采集单元采集的初步数据中抓取同步数据 的方式, 获得了各个数据采集单元的多组同步数据, 每组同步数据都是各个数据采集单元在 同一时刻的准确数据, 从而使得利用该多组同步数据的应用程序可以避免误差的产生。 实施例三
请参考图 3, 其示出了本发明实施例三提供的数据采集装置的结构方框图。 所述数据采 集装置 30可以用于包括多个数据采集单元 301的装置中, 比如个人电脑、服务器之类的固定 终端, 或者诸如笔记本、 平板电脑和手机之类的移动终端, 该移动终端通常还包括多个同步 数据使用模块 302。 所述数据采集装置 30可以包括: 采集单元注册模块 303、 工作模式设定 模块 304、 初始化时间获取模块 305、 起始时刻获取模块 306、 初始化时刻获取模块 307、 初 始化模块 308、 采集频率获取模块 309、 公约数获取模块 310、 同步采集频率选取模块 311和 同步数据采集模块 312。
数据采集单元 301用于按照一定的采集频率采集初步数据。 数据采集单元 301可以是移 动终端中的各种传感器, 此处的采集频率既可以指传感器的实际采集频率, 也可以指传感器 上报初步数据的频率。 数据采集单元 301通常包括两种工作模式: 第一工作模式, 判断本次 采集的数据与前次采集的数据之差是否大于预定阀值, 如果是, 则将本次采集的数据作为初 步数据进行上报; 第二工作模式, 每次采集的数据都作为初步数据进行上报。 并且在通常情 况下, 数据采集单元 301按照第一工作模式运行。
同步数据使用模块 302用于对各个数据采集单元 301采集的同一时刻的数据进行使用或 处理,该各个数据采集单元 301采集的同一时刻的数据即为同步数据。同步数据使用模块 302 可以是应用程序。 其中, 同步数据由同步数据采集模块 312提供。
采集单元注册模块 303用于在同步数据使用模块 302需要同步数据时, 注册所有数据采 集单元 301 中的全部或者部分作为待采集同步数据的数据采集单元 301。 由于在一个终端中 可能包括很多个数据采集单元 301, 而同步数据使用模块 302可能需要的是其中一部分数据 采集单元 301在同一时刻的精确数据。 所以, 同步数据使用模块 302可以通过采集单元注册 模块 303注册所有数据采集单元 301中的全部或者部分作为待采集同步数据的数据采集单元, 待采集同步数据的数据采集单元是同步数据使用模块 302需要获取同步数据相关的数据采集 单元, 对于该终端中的其它数据采集单元, 同步数据使用模块 302可以不注册。
工作模式设定模块 304用于将采集单元注册模块 303注册的每个数据采集单元 301的工 作模式设置从默认的第一工作模式设定为第二工作模式。 该第二工作模式是指数据采集单元 301将每次采集的数据都作为初步数据进行上报的工作模式。
初始化时间获取模块 305用于获取采集单元注册模块 303注册的至少两个数据采集单元 301 的初始化时间长度和初始化时间长度中最大的初始化时间长度。 其中, 初始化时间长度 是指传感器从上电初始化开始到初始化完成并进行第一次数据采集的这段时间。 对于不同的 数据采集单元 301, 该初始化时间长度可以互不相同。
起始时刻获取模块 306用于获取所述采集起始时刻, 所述采集起始时刻不小于在当前时 刻基础上向后延长所述最大的初始化时间长度得到的时刻。
初始化时刻获取模块 307, 用于获取采集单元注册模块 303注册的至少两个数据采集单 元 301的初始化时刻, 采集单元注册模块 303注册的至少两个数据采集单元 301的初始化时 刻可以为在起始时刻获取模块 306获取的采集起始时刻基础上提前数据采集单元 301各自的 初始化时间长度得到的时刻。
初始化模块 308用于根据初始化时刻获取模块 307获取的初始化时刻初始化采集单元注 册模块 303注册的至少两个数据采集单元 301。 当采集单元注册模块 303注册的至少两个数 据采集单元 301同时在起始时刻获取模块 306获取的采集起始时刻完成初始化过程后, 以各 自的采集频率采集初步数据。
采集频率获取模块 309用于获取采集单元注册模块 303注册的至少两个数据采集单元 301 的采集频率。 采集频率是数据采集单元 301在第二工作模式下采集初步数据时的频率。 需要 说明的是, 每个传感器的采集频率可能不止一个, 此时可以获取该传感器的所有采集频率, 此处的采集频率既可以指传感器的实际采集频率, 也可以指传感器上报初步数据的频率。
公约数获取模块 310用于获取采集频率获取模块 330获取的至少两个数据采集单元 301 的采集频率的数值的所有公约数。
同步采集频率选取模块 311用于选取公约数获取模块 310获取的所有公约数中的一个作 为同步采集频率的数值。 在一个具体的实施例中, 该同步采集频率选取模块 311又可以具体 包括需求频率获取单元 3112和同步采集频率确定单元 3114, 如图 4所示。 其中, 需求频率 获取单元 3112用于获取同步数据的需求频率,该需求频率为同步数据使用模块 302使用同步 数据时所需要的频率;同步采集频率确定单元 3114用于选取公约数获取模块 310获取的公约 数中不小于需求频率获取单元 3112 获取的需求频率的数值的最小一个公约数作为同步采集 频率的数值。
由于可能同时有多个同步数据使用模块 302需要使用同步数据, 所以需求频率获取单元 3112 又可以具体包括有最低频率获取子单元和需求频率选取子单元 (未具体示出)。 其中, 最低频率获取子单元用于获取各个同步数据使用模块 302 使用同步数据时所需要的最低频 率; 需求频率选取子单元用于选取最低频率获取子单元获取到的各个最低频率的数值的最小 公倍数作为需求频率的数值。
同步数据采集模块 370用于根据同步采集频率选取模块 311选取的同步采集频率采集每 个数据采集单元 301采集的初步数据以获取同步数据。
在一个具体的实施例中, 数据采集装置可以为智能手机, 该智能手机包括陀螺仪传感器、 重力加速度传感器、 红外传感器和电子罗盘传感器, 这四个传感器可以是四个数据采集单元 301。 该智能手机中运行的一个赛车游戏可以是一个同步数据使用模块 302。 当这个赛车游戏 被用户触发运行后, 这个赛车游戏可以利用采集单元注册模块 303注册陀螺仪传感器和重力 加速度传感器作为待采集同步数据的至少两个数据采集单元 301,然后工作模式设定模块 304 将陀螺仪传感器和重力加速度传感器的工作模式从默认的第一工作模式设定为每次采集到数 据都作为初步数据上报的第二工作模式。 初始化时间获取模块 305可以获取到陀螺仪传感器 的初始化时间长度为 190ms, 而重力加速度传感器的初始化时间长度为 120ms, 这两者之间的 最大的初始化时间长度为 190ms。假设预定时间长度为 100ms, 则起始时刻获取模块 306可以 将 (当前时刻 +190mS+100ms ) 所指示的时刻作为采集起始时刻, 而初始化时刻获取模块 307 则可以将(当前时刻 +190ms+100ms-190ms ) = (当前时刻 +100ms )所指示的时刻作为陀螺仪传 感器重新初始化的初始化时刻, 同时将(当前时刻 +190mS+100mS-120ms ) = (当前时刻 +170ms ) 所指示的时刻作为重力加速度传感器重新初始化的初始化时刻。 初始化模块 308则启动相应 的定时器使得陀螺仪传感器在 (当前时刻 +100ms ) 所指示的时刻开始重新初始化, 同时使得 重力加速度传感器在 (当前时刻 +170ms ) 所指示的时刻开始重新初始化。 显然, 陀螺仪传感 器和重力加速度传感器都会在采集起始时刻同时完成初始化, 并且开始以各自的采集频率开 始采集初步数据。
另一方面, 在陀螺仪传感器和重力加速度传感器被注册以后, 采集频率获取模块 309可 以获取到陀螺仪传感器的采集频率为 100HZ, 重力加速度传感器的采集频率为 200HZ。公约数 获取模块 310获得公约数频率的数值可以为 1、 2、 4、 5、 10、 20、 25、 50和 100。 同步采集 频率选取模块 311中的需求频率获取单元 3112获取到该赛车游戏需要以最低为 25HZ的需求 频率来使用同步数据, 则同步采集频率选取模块 311 中的同步采集频率确定单元 3114选取 25HZ作为同步采集频率。 同步数据采集模块 370可以在采集起始时刻之后, 利用该同步采集 频率采集陀螺仪传感器和重力加速度传感器采集的初步数据从而获得同步数据。 最后, 该赛 车游戏可以利用该同步数据计算游戏时的各种参数。
当然, 在该赛车游戏退出运行时, 可以通过采集单元注册模块 301注销对陀螺仪传感器 和重力加速度传感器的注册, 工作模式设定模块 302可以将陀螺仪传感器和重力加速度传感 器的工作模式从第二工作模式设定为原先默认的第一工作模式。 综上所述, 本实施例三提供的数据采集装置通过调整至少两个数据采集单元的采集起始 时刻, 并同时按照同步采集频率从该至少两个数据采集单元采集的初步数据中抓取同步数据 的方式, 获得了各个数据采集单元的多组同步数据, 每组同步数据都是各个数据采集单元在 同一时刻的准确数据, 从而使得利用该多组同步数据的应用程序可以避免误差的产生。 需要说明的是: 上述实施例提供的数据采集装置在实施例三中描述时, 仅以上述各功能 模块的划分进行举例说明, 实际应用中, 可以根据需要而将上述功能分配由不同的功能模块 完成, 即将装置的内部结构划分成不同的功能模块, 以完成以上描述的全部或者部分功能。 另外, 上述实施例提供的数据采集终端与数据采集方法实施例属于同一构思, 其具体实现过 程详见方法实施例, 这里不再赘述。 本领域普通技术人员可以理解实现上述实施例的全部或部分步骤可以通过硬件来完成, 也可以通过程序来指令相关的硬件完成,所述的程序可以存储于一种计算机可读存储介质中, 上述提到的存储介质可以是只读存储器, 磁盘或光盘等。 以上所述仅为本发明的较佳实施例, 并不用以限制本发明, 凡在本发明的精神和原则之 内, 所作的任何修改、 等同替换、 改进等, 均应包含在本发明的保护范围之内。
