图2是本发明智能手表锁屏管理方法第二实施方式的流程示意图；
图3是本发明智能手表锁屏管理系统第一实施方式的结构示意图；
图4是本发明智能手表第一实施方式的结构示意图。
【具体实施方式】
请参阅图1，图1是本发明智能手表锁屏管理方法第一实施方式的流程示意图，本实施方式智能手表锁屏管理的方法基于包括心率传感器的智能手表，其包括以下步骤。
S101：心率传感器读取心率值。
智能手表佩戴在用户手上时，智能手表上的心率传感器读取用户的心率，得到心率值。
心率传感器主要有电极心率传感器和光电心率传感器两种，其中电极心率传感器检测更为精准，但必须同时检测人体的两个部位，因此不容易实现持续检测。当智能手表主要用作医疗时，需要准确数据时，则采用电极心率传感器。
当前智能手表上多数采用光电心率传感器，即通过检测器及光源，光源能够照射到皮下毛细血管，当心脏将新鲜血液压入到毛细血管时，亮度会呈现波浪状的周期性变化，通过检测器检测这一有规律的变化，即得到了心率值。
本实施方式中也采用光电心率传感器，检测心率值需要光源和检测器的配合；其中光源可以一直保持发光，而检测器定期检测，这种情况下光源发光消耗功率较多，不利于智能手表电池续航。也可以光源以一定周期发光，检测器也相应的在光源发光时进行检测，该情况一定程度上能够减少了功率的消耗。这两种情况下的周期均为得到心率值的周期T1，该检测心率值的周期T1取值范围为0.01s~0.5s，由于人体在安静状态下心率一般为60-100次/分钟，因此为了保证检测的准确率，将该检测周期T1的最大值设置为0.5s； 周期越小，所检测的值越准确，但若周期设置的过小，则容易造成功率消耗过大，因此基于节能的考虑，将检测周期T1最小值设置为0.01s。
S102：根据心率值判断智能手表是否被用户取下。
在本实施方式中心率值用于判断智能手表是否被用户取下，当佩戴时心率传感器能够检测到心率值，而取下后心率传感器无法检测到心率值。即本步骤S102中需要判断心率值是否从有变无，若是则表示智能手表被取下；若心率值还是为有，则表示智能手表未被取下。
然而智能手表并不是时刻都紧贴在手上，可能出现佩戴在手上但无法检测出心率值的情况，因此本步骤S102中判断智能手表被取下的条件为：心率值从有变无，且持续一段时间T2无法检测到心率值。对于T2的取值，若取值太小，则容易导致误锁屏，即当佩戴在手上太过松散，一段时间内无法检测到心率值时，自动锁屏，造成较差的用户体验；若取值太大，则导致不能及时进行锁屏，依旧容易造成安全问题。因此本实施方式中T2取值范围为5s~30s。
具体来说，当检测心率值的周期T1为0.5s时，若心率值从有变为无，且持续30s无法检测到心率值，即T2=30s，则判断智能手表被取下；当检测心率值的周期T1为0.01s时，若心率值从有变为无，且持续5s无法检测到心率值，即T2=5s，则判断智能手表被取下。较优的情况是检测心率值的周期T1设置为0.1s，能够保证检测准确性的同时，节省功耗，达到两者的平衡；而T2设置为10s，即心率从有变为无，且持续10s无法检测到心率值，则判断智能手表被取下，10s的设置符合大多数人的使用情况。当然，也可在智能手表中对T1和T2做个性化设置，即用户可根据自己使用智能手表的具体情况对T1、T2进行设置。
而使用本实施方式的智能手表并不仅仅具有本发明锁屏管理的功能，其还可能具有分析运动情况、睡眠质量、身体健康的功能，由于光电心率传感器检测的准确度不高，因此本实施方式中还需通过专门的电路对心率值进行调整修正。
本步骤S102中判断出智能手表是被用户取下后进入步骤S103。
S103：心率传感器停止工作且智能手表进入密码锁屏模式。
在智能手表被取下后，即心率传感器无法检测到心率值，此时心率传感器自动停止工作，以减少能耗。智能手表则进入到密码锁屏模式，即智能手表的屏幕变暗，且若需进入到主界面，则需要输入密码。
为了保证智能手表的基本功能，即用户只需要通过智能手表知道时间。在本实施方式中，智能手表进入到密码锁屏模式后，其屏幕仅显示时间，若想进行其他操作，则应输入密码。
请参阅图2，图2是本发明智能手表管理方法第二实施方式的流程示意图，该实施方式中智能手表包括心率传感器，而锁屏管理的方法包括以下步骤。
S201：心率传感器读取心率值。
S202：根据心率值判断智能手表是否被用户取下。
若是，则进入步骤S203，若否，则进入步骤S204。
S203：心率传感器停止工作且智能手表进入密码锁屏模式。
本实施方式中的步骤S201-S203与第一实施方式中的步骤S101-S103类似，具体不再赘述。
S204：智能手表保持解锁状态，或者智能手表保持无密码锁屏模式。
在判断智能手表未被用户取下，即一直佩戴在用户手上时，智能手表保持解锁状态，即无需输入密码即可进行所有操作。或者智能手机保持无密码锁屏状态，即触碰屏幕或按动某个物理键即可进入到智能手表的主界面，而无需输入密码。
S205：进入智能手表的密码输入界面。
智能手表被用户取下，经过步骤S203进入锁屏模式后。若用户需要进入智能手表的主界面进行操作，则首先进入密码输入界面，然后进行步骤S206。
S206：输入密码使智能手表进入解锁状态。
本实施方式中可采用两种密码模式，即图案密码或数字密码。而输入密码则分别对应输入图案或数字，图案密码为9个三三排列的点，任选4个连线，考虑到表盘的一般较小，因此优选数字密码的模式。
请参阅图3，图3是本发明智能手表锁屏管理系统第一实施方式的结构示意图。本实施方式智能手表包括心率传感器，锁屏管理系统300包括判断模块31以及锁屏模块32。
其中判断模块31则根据心率传感器读取的心率值判断智能手表是否被用户取下，得到判断结果。
锁屏模块32读取该判断结果，在判断结果为是时，使智能手表进入密码锁屏模式，且心率传感器在判断结果为是时停止工作。
在判断结果为否时，锁屏模块32使智能手表保持解锁状态，或使智能手表保持无密码锁屏模式。
锁屏模块32进一步用于在智能手表进入密码锁屏模式后，提供智能手机的密码输入界面，并接收输入密码，使智能手机进入解锁状态，该密码可以为图案密码或数字密码。
本实施方式中的各个模块的功能对应于智能手表锁屏管理方法第二实施方式中的各个步骤，各个模块具体的工作过程在此不再赘述
请参阅图4，图4是本发明智能手表第一实施方式的结构示意图。本实施方式智能手表400包括心率传感器41以及处理器42。
心率传感器41读取心率值，处理器42根据心率值判断智能手表400是否被取下，若是，则处理器42控制心率传感器41停止工作且使智能手表400进入密码锁屏模式。
本实施方式中的处理器42用于完成智能手表锁屏管理方法中的步骤，因此对于其工作过程不再作具体描述。
需要说明的是，本实施方式中处理器42可设置在表盘内；而心率传感器41则设置在智能手表400表盘贴近用户皮肤的一侧，由于表盘接触的皮肤面积较多，因此将心率传感器41设置在表盘检测心率值时出现的错误会更少。
若需要对所检测到的心率值进行分析处理，在智能手表400中还可增加一修正电路（图未示），连接处理器42，修正电路可设置在表盘内或表带内，用以对所测得的心率值进行调整修正。
区别于现有技术，本发明为具有心率传感器的智能手表锁屏管理的方法，该方法包括步骤：心率传感器读取心率值；根据心率值判断智能手表是否被用户取下，若是，则心率传感器停止工作且智能手表进入密码锁屏模式，该方法保证了在智能手表被取下时，智能手表能够自动进入密码锁屏模式，用户不需手动锁屏，提高了用户体验，并且避免了因用户忘记锁屏而造成的安全问题。
以上所述仅为本发明的实施方式，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
