具体实施方式
这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本申请相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本申请的一些方面相一致的方法的例子。
图1是本申请一个实施例提供的实施环境的示意图。该实施环境可以包括:终端10、心跳采集设备20和服务器30。
在本申请实施例中,终端10是指用于采集录音数据的设备。终端10上可以安装有出行类应用程序,例如,该出行类应用程序可以包括打车类应用程序、导航类应用程序或其他应用程序等,本申请实施例对终端10上安装的出行类应用程序的类型和数量不做限定。可选地,终端10上设置有麦克风,该麦克风用于采集录音数据。出行类应用程序具有访问终端10的麦克风权限,以采集录音数据。示例性地,终端10可以是诸如手机、平板电脑、可穿戴设备等电子设备。

在本申请实施例中,服务器30可以是一台服务器,也可以是由多台服务器组成的服务器集群。可选地,服务器30是用于存储行程片段中的录音片段和行程片段各自的重要度参数的设备。
在一个示例中,如图2所示,以打车出行场景为例,出行工具为汽车,终端10可以是司机使用的手机,心跳采集设备20可以是手环。汽车内配置有手 机和手环,手机用于录音,手环由司机和乘客分别佩戴,用于分别采集司机和乘客的心跳数据。乘客上车后,司机和乘客手环佩戴就绪成功后,同步开始采集司机心跳、采集乘客心跳和录音。乘客下车后(即打车订单完成后),录音结束,停止心跳统计,获得与录音数据相同起止时间的2份心跳数据,心跳数据随录音数据一起上传服务器30。
为了便于介绍,下面将以各步骤的执行主体为计算机设备为例进行介绍说明,计算机设备是指具备计算和处理能力的电子设备,计算机设备包括终端或服务器,但不应对本申请实施例造成限定。下面,通过几个实施例对本申请技术方案进行介绍说明。
请参考图3,其示出了本申请一个实施例提供的数据存储方法的流程图。在本实施例中,主要以该方法应用于上文介绍的计算机设备中来举例说明。该方法可以包括如下几个步骤:
步骤301,获取出行期间的行程数据。
在本申请实施例中,行程数据包括录音数据和心跳数据。出行期间是指乘客上车至乘客下车之间的时间段。录音数据和心跳数据的起止时间一致,录音数据可以仅包括司机的录音数据,也可以仅包括乘客的录音数据,还可以包括司机和乘客之间的录音数据。心跳数据可以仅包括司机的心跳数据,也可以仅包括乘客的心跳数据,还可以包括司机的心跳数据和乘客的心跳数据。
示例性地,终端将录音数据发送给计算机设备,心跳采集设备将心跳数据发送给计算机设备,相应地,计算机设备接收来自于终端的录音数据,以及来自于心跳采集设备的心跳数据。
步骤302,将行程数据拆分为n个行程片段,n为正整数。
在本申请实施例中,行程片段包括录音数据对应的录音片段和心跳数据对应的心跳片段。若心跳数据包括司机的心跳数据和乘客的心跳数据,则行程片段包括录音片段、司机的心跳数据对应的司机心跳片段、乘客的心跳数据对应的乘客心跳片段;若心跳数据仅包括司机的心跳数据,则行程片段包括录音片段和司机心跳片段;若心跳数据仅包括乘客的心跳数据,则行程片段包括录音片段和乘客心跳片段。
可选地,n个行程片段各自的时长一致,也即,n个录音片段各自的时长一 致,n个心跳片段各自的时长一致,录音片段和心跳片段的时长一致。例如,行程片段的时长都为30秒。当存在拆分后的行程片段不足30秒的时候,将其补至30秒,例如,拆分后的行程片段为5秒,则将上述5秒复制5遍补足剩下的25秒,得到时长为30秒的行程片段;又例如,拆分后的行程片段为4秒,则将上述4秒复制6.5遍以补足剩下的26秒,得到时长为30秒的行程片段。
步骤303,计算n个行程片段各自的重要度参数。
在本申请实施例中,重要度参数用于表征行程片段在出行期间的重要程度。重要度参数越大,表示该行程片段在出行期间越重要;重要度参数越小,表示该行程片段在出行期间越不重要。出行期间的不同时间段的重要度参数可能不同。可选地,重要度参数可以表示为权重。
行程片段的重要度参数可以根据录音片段的重要度参数和心跳片段的重要度参数确定。
步骤304,将n个行程片段中的录音片段和n个行程片段各自的重要度参数对应存储。
例如,存在5个行程片段,每个行程片段的重要度参数分别为5、2、4、3、4,则计算机设备可以将第一个行程片段中的录音片段与5对应存储,将第二个行程片段中的录音片段与2对应存储,将第三个行程片段中的录音片段与4对应存储,将第四个行程片段中的录音片段与3对应存储,将第五个行程片段中的录音片段与4对应存储。上述录音片段按照出行期间的时间顺序进行存储。
示例性地,录音片段和重要度参数对应存储在服务器中,上述重要度参数由终端确定,当终端确定好n个行程片段各自的重要度参数之后,将n个行程片段中的录音片段和n个行程片段各自的重要度参数发送给服务器,以使得服务器将上述n个行程片段中的录音片段和n个行程片段各自的重要度参数对应存储。
示例性地,上述重要度参数由服务器确定,当服务器确定好n个行程片段各自的重要度参数之后,将n个行程片段中的录音片段和n个行程片段各自的重要度参数对应存储在服务器本地。
综上所述,本申请实施例提供的技术方案中,通过获取出行期间的行程数据,行程数据包括录音数据和心跳数据,将行程数据拆分为n个行程片段,并计算n个行程片段各自的重要度参数,将行程片段中的录音片段和行程片段的 重要度参数对应存储。本申请实施例从心跳和声音两个维度来评估打车录音片段,区分了不同片段的重要程度。且将录音片段和重要度参数对应存储,可以方便用户获悉录音片段的重要程度。
另外,本申请实施例可以根据不同片段的重要程度制定不同的储存策略,从而优化了储存方案。
在可能的实现方式中,计算机设备通过如下方式计算n个行程片段各自的重要度参数:
第一、计算录音片段的重要度参数。
第二、计算心跳片段的重要度参数。
需要说明的是,上述录音片段的重要度参数和心跳片段的重要度参数可以一起计算;也可以先计算录音片段的重要度参数,再计算心跳片段的重要度参数;还可以先计算心跳片段的重要度参数,再计算录音片段的重要度参数,本申请实施例对这两个步骤的执行顺序不作限定。
有关录音片段的重要度参数和心跳片段的重要度参数的计算流程参见下文实施例。
第三、根据录音片段的重要度参数和心跳片段的重要度参数,确定行程片段的重要度参数。
可选地,此步骤包括如下几个子步骤:
1、响应于录音片段的重要度参数是第四参数,将第四参数确定为行程片段的重要度参数。
若录音片段的重要度参数是第四参数,则表明该录音片段是沉默片段,不需要叠加心跳片段的重要度参数。
2、响应于录音片段的重要度参数不是第四参数,将录音片段的重要度参数和心跳片段的重要度参数之和,确定为行程片段的重要度参数。
若录音片段的重要度参数不是第四参数,则表明该录音片段不是沉默片段,需要考虑心跳片段的重要度参数,将录音片段的重要度参数和心跳片段的重要度参数之和,确定为行程片段的重要度参数。每个行程片段对应有各自的录音片段和心跳片段,而每个录音片段和心跳片段的重要度参数可能不同,因此,每个行程片段的重要度参数可能也不同,即,每个行程片段在出行期间的重要 程度不同。
在可能的实现方式中,录音数据包括第一用户和第二用户在出行期间的录音数据,心跳数据包括第一用户对应的第一心跳数据以及第二用户对应的第二心跳数据。
此时,计算机设备可以将录音片段、第一心跳数据对应的第一心跳片段以及第二心跳数据对应的第二心跳片段各自的重要度参数之和,确定为行程片段的重要度参数。
可选地,计算机设备将n个行程片段中的录音片段和n个行程片段各自的重要度参数对应存储之后,还可以执行以下步骤:
第一、每隔预设时间间隔检测行程片段的重要度参数。
例如,每天检测行程片段的重要度参数。
第二、响应于行程片段的重要度参数满足删除条件,删除行程片段中的录音片段以及行程片段的重要度参数。
可选地,删除条件为行程片段的重要度参数为0。当行程片段的重要度参数为0时,删除行程片段中的录音片段以及行程片段的重要度参数,释放空间。
第三、响应于行程片段的重要度参数不满足删除条件,更新行程片段的重要度参数。
可选地,当行程片段的重要度参数不为0时,将行程片段的重要度参数与1的差值确定为行程片段更新后的重要度参数。
在可能的实现方式中,当行程片段更新后的重要度参数满足删除条件时,删除行程片段中的录音片段以及行程片段的重要度参数,因而不需要在下次检测时再进行删除,提高了删除效率。
在示意性实施例中,以心跳数据包括乘客和司机各自的心跳数据、重要度参数为权重为例进行说明。如图4所示,将录音片段权重、司机心跳片段权重、乘客心跳片段权重按照时间顺序对应。检测录音片段是否是沉默片段;若录音片段不是沉默片段,则将上述3个权重进行叠加,得到最终的权重;若录音片段是沉默片段,则不叠加心跳片段权重。将录音片段以及最终的权重对应存储。每天检查行程片段的权重;若行程片段的权重为0,则删除录音片段,释放空间;若行程片段的权重不为0,则将权重-1,再次执行每天检查行程片段的权重。
综上所述,本申请实施例提供的技术方案中,对不同重要度参数的录音片 段按照不同策略进行储存,能够优化储存空间,同时缩短了不重要录音片段占用储存空间的时间,延长了重要录音片段的保存时间。

在可能的实现方式中,步骤503包括如下几个子步骤:
步骤503a,响应于能量值属于第一取值范围,将第一参数确定为录音片段的重要度参数。
第一取值范围包括高于第一预设倍数的平均能量值的范围。可选地,第一预设倍数为120%,即第一取值范围包括高于120%的平均能量值,第一参数为4。当能量值高于平均能量值的120%时,将4确定为录音片段的重要度参数。
示例性地,能量值属于第一取值范围的录音片段可以称为高能量片段。
步骤503b,响应于能量值属于第二取值范围,将第二参数确定为录音片段的重要度参数。
第二取值范围包括第二预设倍数的平均能量值至第一预设倍数的平均能量值之间的范围。可选地,第二预设倍数为80%,即第二取值范围为平均能量值的80%至平均能量值的120%,第二参数为3。当能量值属于平均能量值的80%至平均能量值的120%时,将3确定为录音片段的重要度参数。
示例性地,能量值属于第二取值范围的录音片段可以称为平均能量片段。
步骤503c,响应于能量值属于第三取值范围,将第三参数确定为录音片段 的重要度参数。
第三取值范围包括第三预设倍数的平均能量值至第二预设倍数的平均能量值之间的范围。可选地,第三预设倍数为10%,即第三取值范围为平均能量值的10%至平均能量值的80%,第三参数为2。当能量值属于平均能量值的10%至平均能量值的80%时,将2确定为录音片段的重要度参数。
示例性地,能量值属于第三取值范围的录音片段可以称为低能量片段。
步骤503d,响应于能量值属于第四取值范围,将第四参数确定为录音片段的重要度参数。
第四取值范围包括低于第三预设倍数的平均能量值的范围。可选地,第四取值范围为低于平均能量值的10%,第四参数为1。当能量值低于平均能量值的10%时,将1确定为录音片段的重要度参数。
示例性地,能量值属于第四取值范围的录音片段可以称为沉默片段。
需要说明的是,上述有关第一取值范围、第二取值范围、第三取值范围、第四取值范围的举例仅是示例性地,在可能的实现方式中,其还可以是其它取值范围,本申请实施例对此不作限定。
需要说明的是,上述有关第一参数、第二参数、第三参数和第四参数的举例仅是示例性地,在可能的实现方式中,其还可以是其它值,本申请实施例对此不作限定。
可选地,如图6所示,计算机设备通过如下几个子步骤计算心跳片段的重要度参数:
步骤601,将第m个心跳片段的真实心跳值输入心跳预测模型中,得到第m+1个心跳片段的预测心跳值,m为小于或等于n的正整数。
可选地,心跳预测模型使用线性回归算法。从第一个心跳片段开始,对心跳建模,使用线性回归算法,预测下一个心跳片段的心跳数。
步骤602,响应于第m+1个心跳片段的真实心跳值大于第四预设倍数的预测心跳值,确定第m+1个心跳片段对应心跳加快。
可选地,第四预设倍数为105%,当第m+1个心跳片段的真实心跳值大于预测心跳值的105%时,确定第m+1个心跳片段对应心跳加快。需要说明的是,在可能的实现方式中,当第m+1个心跳片段的真实心跳值上涨超过预测心跳值 的5%时,确定第m+1个心跳片段对应心跳加快。
步骤603,响应于第m+1个心跳片段的真实心跳值小于第五预设倍数的预测心跳值,确定第m+1个心跳片段对应心跳平复。
可选地,第五预设倍数为95%,当第m+1个心跳片段的真实心跳值小于预测心跳值的95%时,确定第m+1个心跳片段对应心跳平复。需要说明的是,在可能的实现方式中,当第m+1个心跳片段的真实心跳值下降超过预测心跳值的5%时,确定第m+1个心跳片段对应心跳平复。
需要说明的是,响应于第m+1个心跳片段的真实心跳值处于第五预设倍数的预测心跳值至第四预设倍数的预测心跳值之间时,确定第m+1个心跳片段对应心跳维持。心跳维持对应的重要度参数可以为0。
步骤604,计算心跳抖动的平均心跳值。
心跳抖动包括心跳加快至心跳平复之间的心跳片段,第m+1个心跳片段属于心跳抖动。可选地,计算心跳加快至心跳平复之间的心跳片段的真实心跳值的平均值,得到心跳抖动的平均心跳值。例如,假设心跳抖动包括4个心跳片段,则计算该4个心跳片段的真实心跳值的平均值,即可得到心跳抖动的平均心跳值。
步骤605,计算n个心跳片段的真实心跳值的平均值,得到整体平均心跳值。
假设存在5个心跳片段,每个心跳片段的真实心跳值分别为30、50、40、45、55,则整体平均心跳值为(30+50+40+45+55)/5=44。
步骤606,根据平均心跳值、整体平均心跳值和第二参数赋予规则,确定第m+1个心跳片段的重要度参数。
第二参数赋予规则是指用于确定心跳片段的重要度参数的规则。
