具体实施方式
下面结合说明书附图对本发明实施例作详细描述。
因为心率变化和人的运动状态强相关，睡眠或者静止状态下心率很平稳，可以以第一启动周期和第一采样率周期性的对用户进行心率检测；走路时心率变化相对缓慢，可以以第二启动周期和第二采样率周期性的对用户进行心率检测；跑步时运动相对剧烈，心率变化相对较快，可以以第三启动周期和第三采样率周期性的对用户进行心率检测，检测用户心率变化提醒指导用户；其中，第一启动周期>第二启动周期>第三启动周期。同时随着运动状态的变化，每分钟心跳数也会随运动状态变化而变化，如跑步时活动较为剧烈，心跳变快，为了准确检测心率，采样率也会用户运动状态的不同，而进行适应性的调整，可以是：第三采样率>第二采样率>第一采样率。根据该实现原理以下对本发明实施例所提供的方法做进一步具体的说明：
实施例一
如图1所示，本发明实施例提供一种电子设备，该电子设备包括：处理器101、显示单元102、充电芯片103、蓝牙模块104、心率模组105、运动传感器106和时钟107；
显示单元102，实现电子设备显示输出内容个显示，在该实施例中可以是液晶显示(Liquid Crystal Display，LCD)屏；
充电芯片103，实现电子设备充电管理；
蓝牙模块104，实现该电子设备与其他电子设备的通信；
心率模组105，用于测试心率时采集用户血管随脉搏变化的数据，供心率算法计算心率值；
可选的，该心率模组105可以包括：实现心率算法的控制芯片、PPG传感器以及加速度传感器(acceleration transducer，ACC)等等；
运动传感器106，用于采集用户运动过程中三轴方向的加速度值，并根据该加速度值确定用户当前的运动状态；
在本发明实施例所提供的方案中，包括：
所述处理器101，具体用于根据预存的运动状态与启动周期和采样率的对应关系，确定所述当前运动状态所对应的启动周期和采样率；并以所述启动周期定期开启所述心率传感器以所述采样率采集心率数据；其中，所述启动周期为启动所述心率传感器对携带所述电子设备的用户的心率进行检测的周期；所述采样率为所述心率传感器采集心率数据的采样率。
可选的，该处理器101还用于根据预设的检测周期启动所述运动传感器检测所述用户的当前运动状态；其中，所述检测周期为启动所述运动传感器对所述用户进行运动状态检测的周期。
在该实施例所提供的方式中可以根据预设的检测周期周期性的开启运动传感器，从而减少运动传感器一直开启所带来的不必要能耗。该检测周期可以根据具体需要进行合理的设置。
可选的，该处理器101还用于获取存储的历史运动状态；将所述当前运动状态与所述历史运动状态进行比较，如果不相同，则根据预存的运动状态与启动周期和采样率的对应关系，确定所述当前运动状态所对应的启动周期和采样率；其中，所述历史运动状态为预存的所述用户的运动状态信息。
该实施例所提供的方式中，只有确定当前检测到的运动状态与历史的运 动状态(历史的运动状态可以是前一次运动状态检测所获取到的运动状态信息)不一样，才会进行启动周期和采样率的调整。这样可以减少对心率传感器的不必要操作，延长心率传感器的寿命。其中，如果当前检测是第一次进行运动状态检测，则直接确定当前运动状态与历史运动状态不相同。
其中，因为本发明实施例是基于运动状态的不同采用不同的启动周期和采样率进行心率数据监测，则心率与运动状态强相关的特性，在该实例中预设的运动状态与检测周期以及采样率的对应关系可以是：
运动状态所对应的运动强度与检测周期的时间间隔成反比，运动状态所对应的运动强度与采样率成正比。
本发明实施例所提供的方案中根据用户运动状态，来确定开启自动检测心率的启动时间和测试心率时心率传感器的采样率。例如：
用户睡眠或者静止时，定时一个小时检测一次心率，采样率设置为25HZ；用户走路时，定时30分钟检测一次心率,采样率设置为50HZ；用户跑步时，定时10分钟检测一次心率,采样率设置为100HZ。
实施例二
如图2所示，结合具体的使用环境，本发明实施例提供的一种心率实时检测方法的具体实现方式，可以通过以下具体步骤实现：
步骤201，电子设备开启后，电子设备首先检测心率检测机制是否已开启，如果开启，可以设置定时器1定时10分钟，其中心率传感器(可以是PPG)的采样率为100HZ；
在该实施例中，因为电子设备开启心率检测机制之后，电子设备不能明确当前进行心率检测的具体周期是多长时间，如果固定的心率检测周期时间间隔很长，则会导致电子设备需要等待给很长的时间周期才能进行下一次心率检测。所以为了使得心率检测的周期更合理，可以预先设置一个定时器1， 电子设备可以根据该定时器直接进行一次心率检测，并开启对应的运动检测机制。
步骤202，定时器1到后，检测运动状态是否有变化(如果是第一次触发心率检测，则直接确定运动状态有变化)，有变化则开启检测心率一次，并转入步骤203；
在该实施例中，定时器是与电子设备开启心率传感器的启动周期相关的，以下提供两种最优化的设置定时器的方式，具体可以是：
A，电子设备根据运动状态的不同实时调整定时器1的参数值；例如：如果用户当前运动强度大，则定时器定时时长小；如果运动强度小，则定时时长大。
B，电子设备设置两个定时器，定时器1和定时器2；其中定时器1为固定的定时时长，例如10分钟。定时器2则与用户的运动状态一一对应，定时器2的设置可以参照表1所示的实例(表1中所提供的数值只是为了举例说明该实施例的方案，并不限定本发明实施例中的定时时长只能为表1所示的数值)：
用户的运动状态 定时器2的时长 采样率
睡眠/静止 1小时 25HZ
走路 30分钟 50HZ
跑步/骑行 10分钟 100HZ
表1
在该实施例中，可以采用PPG Sensor和加速度传感器(acceleration transducer，ACC)组合使用采集与用户运动相关的参数，利用采集到的参数根据预设的心率算法和状态识别算法确定用户的运动状态。
步骤203，心率检测后，获取运动状态，根据检测到的运动状态设置定时 器的定时时长和心率传感器采样率；
在该实施例中，基于具体实例中定时器的个数，在设置定时器的定时时长时，对应设置定时器1或定时器2的定时时长。
步骤204，然后继续等待定时器1是否到时，当定时器1触发后转入步骤202；否则继续等待；如果检测到关闭心率检测机制的命令，则退出检测。
实施例三
如图3所示，为了实现实施例一所提供的方法，本发明实施例还提供一种心率实时检测装置，该装置包括：
检测单元301，用于用于检测携带该装置的用户的当前运动状态；
可选的，该检测单元301具体用于根据预设的检测周期启动该装置中设置的运动传感器检测所述用户的当前运动状态；其中，所述检测周期为启动所述运动传感器对所述用户进行运动状态检测的周期。
确定单元302，用于用于根据预存的运动状态与启动周期和采样率的对应关系，确定所述当前运动状态所对应的启动周期和采样率；其中，所述启动周期为启动该装置中的心率传感器对携带该装置的用户的心率进行检测的周期；所述采样率为所述心率传感器采集心率数据的采样率；
可选的，该确定单元302具体用于获取存储的历史运动状态；其中，所述历史运动状态为预存的所述用户的运动状态信息；将所述当前运动状态与所述历史运动状态进行比较，如果不相同，则根据预存的运动状态与启动周期和采样率的对应关系，确定所述当前运动状态所对应的启动周期和采样率。
调整单元303，用于以所述启动周期定期开启所述心率传感器以所述采样率采集心率数据。
上述本申请实施例中的技术方案，至少具有如下的技术效果或优点：
本发明实施例所提供的方法及装置中根据用户运动状态，来确定开启自 动检测心率的时间和测试心率时心率传感器的采样率。从而既可以保证心率检测的实时性，又可以保证采集的数据连续性，有利于算法精度，同时可以达到省电的目的。
