进一步地，处理器1001可以调用存储器1004中存储的睡眠阶段的监测程序，还执行以下操作：
判断所述用户是否处于睡眠状态；
在所述用户处于所述睡眠状态时，则执行所述实时或定时通过雷达传感器获取用户的运动幅度变化率的步骤。
进一步地，处理器1001可以调用存储器1004中存储的睡眠阶段的监测程序，还执行以下操作：
实时或定时获取所述用户的运动幅度；
在所述运动幅度小于所述预设运动幅度时，则判定所述用户处于所述睡眠状态。
参照图2，在第一实施例中，所述睡眠阶段的监测方法包括：
步骤S10、实时或定时通过雷达传感器获取用户的运动幅度变化率；
本实施例中，空调器上设置雷达传感器，并由雷达传感器实时或定时获取用户与空调器之间的距离，以根据距离获取用户的运行幅度变化率。具体地，计算本次获取到的距离与上次获取到的距离之间的差值，将该差值作为用户的运动幅度，并计算该差值与上次获取到的距离之间的商值，将该商值作为运动幅度变化率。
需要说明的是，现有技术中的红外以及超声波技术只能检测直线方向的用户，并不能检测用户与空调器之间的距离，而雷达传感器实现360°无死角检测用户，并检测用户与空调器之间的距离。具体地，雷达传感器利用电磁波探测用户，并接收用户的回波，由此获得用户与空调器之间的距离。需要说明的是，雷达传感器通过呼吸、心率来探测人体，若空调器所在环境中存在多个用户，由于不同用户的呼吸频率以及心跳频率有差异，那么不同用户反馈的回波也会有差异。
本实施例中，雷达传感器的位置和数量可根据实际应用进行设置，本申请不做具体限定。
本实施例的执行主体为空调器或者服务器。比如，在执行主体为空调器时，空调器通过雷达传感器获取用户与空调器之间的距离，并根据距离计算用户的运动幅度变化率；在执行主体为服务器时，雷达传感器获取用户与空调器之间的距离，并将该距离发送至服务器，使得服务器根据距离计算用户的运动幅度变化率并反馈。
步骤S20、根据所述运动幅度变化率确定所述用户的睡眠阶段。
本实施例中，用户在睡眠状态下有多个睡眠阶段，比如睡前的清醒期、入睡期、浅睡期、深睡期以及REM，针对不同的睡眠阶段，运动幅度变化率不相同，因此可根据运动幅度变化率确定用户的睡眠阶段。
比如，用户在浅睡期、深睡期以及REM时，浅睡期的运动幅度变化率在20%左右；深睡期的运动幅度变化率在10%左右；REM的运动幅度变化率在30%左右，因此可通过运动幅度变化率确定用户的睡眠阶段。
需要说明的是，也可根据呼吸频率变化率以及运动幅度变化率确定用户的睡眠阶段。具体地，实时或定时通过所述雷达传感器获取用户的运动幅度变化率以及呼吸频率变化率，并根据运动幅度变化率以及呼吸频率变化率确定睡眠阶段。其中，雷达传感器获取空调器所在环境的用户的呼吸间隔，以使得空调器或者服务器根据呼吸间隔计算呼吸频率。呼吸频率变化率的计算方法与运动幅度变化率的计算方法类似，计算本次获取到的呼吸频率与上次获取到的呼吸频率之间的差值，并计算该差值与上次获取到的呼吸频率之间的商值，将该商值作为呼吸频率变化率。
比如，用户在清醒期以及入睡期时，清醒期的运动幅度变化率在50%左右，呼吸频率变化率在15%左右；入睡期的运动幅度变化率在45%左右，呼吸频率变化率在8%左右，因此可通过呼吸频率变化率以及运动幅度变化率确定用户的睡眠阶段。
在第一实施例中，实时或定时通过雷达传感器获取用户的运动幅度变化率，并根据运动幅度变化率确定所述用户的睡眠阶段。这样，通过雷达传感器确定用户所处的睡眠阶段，具有不影响用户睡眠、不影响用户隐私以及精度高的优点。
在第二实施例中，如图3所示，在上述图2所示的实施例基础上，所述根据所述运动幅度变化率确定所述用户的睡眠阶段的步骤包括：
步骤S21、实时或定时通过所述雷达传感器获取所述用户的呼吸频率变化率；
步骤S22、根据所述呼吸频率变化率以及所述运动幅度变化率确定所述睡眠阶段。
本实施例中，空调器上设置雷达传感器，并由雷达传感器实时或定时获取空调器所在环境的用户的呼吸间隔，以使得空调器或者服务器根据呼吸间隔计算呼吸频率。同时，雷达传感器实时或定时获取用户与空调器之间的距离，以根据距离获取用户的运行幅度变化率。具体地，计算本次获取到的呼吸频率与上次获取到的呼吸频率之间的差值，并计算该差值与上次获取到的呼吸频率之间的商值，将该商值作为呼吸频率变化率。需要说明的是，呼吸频率变化率不限于上述计算方法，可根据实际情况进行设置。
比如，用户在清醒期的运动幅度变化率在50%左右，呼吸频率变化率在15%左右；用户在入睡期的运动幅度变化率在45%左右，呼吸频率变化率在8%左右；用户在浅睡期的运动幅度变化率在20%左右，呼吸频率变化率在5%左右；用户在深睡期的运动幅度变化率在10%左右，呼吸频率变化率在2%左右；用户在REM的运动幅度变化率在30%左右，呼吸频率变化率在35%左右，因此可通过呼吸频率变化率以及运动幅度变化率确定用户的睡眠阶段。
在第二实施例中，根据呼吸频率变化率以及运动幅度变化率确定睡眠阶段，这样，保证了睡眠阶段采集的准确性。
在第三实施例中，如图4所示，在上述图2至图3所示的实施例基础上，所述根据所述运动幅度变化率确定所述用户的睡眠阶段之后，还包括：
步骤S30、获取所述睡眠阶段对应的运行参数；
步骤S40、控制所述空调器按照所述运行参数运行。
本实施例中，运行参数包括设定温度、设定湿度、送风风速、送风类型、导风板角度、新鲜度中的至少一个，其中新鲜度包括挥发性有机化合物、PM2.5以及二氧化碳中的至少一个，送风类型包括防直吹、无风感、柔风感等。
具体地，预先设置各个睡眠阶段对应的运行参数，并在检测到用户当前所处的睡眠阶段时，控制空调器按照睡眠阶段对应的运行参数运行。需要说明的是，预先设置各个睡眠阶段的预设时长，在检测到某一睡眠阶段的睡眠时长过短或者过长时，可自动调节运行参数，以保证用户的睡眠质量。比如，在检测到用户处于浅睡期的持续时长大于预设时长时，则自动运行深睡期对应的运行参数，以帮助用户快速进入深睡期。
在第三实施例中，获取睡眠阶段对应的运行参数，并控制空调器按照运行参数运行，这样，保证了用户的睡眠质量。
在第四实施例中，如图5所示，在上述图2至图4所示的实施例基础上，所述获取所述睡眠阶段对应的运行参数之后，还包括：
步骤S401、在获取到多个所述睡眠阶段对应的运行参数时，获取所述睡眠阶段的优先级；
步骤S402、控制所述空调器按照优先级最高的睡眠阶段对应的运行参数运行。
本实施例中，预先设置睡眠阶段的优先级，以在空调器所在环境有多个用户处于睡眠状态，但多个用户处于不同的睡眠阶段时，控制空调器按照优先级最高的睡眠阶段对应的运行参数运行。比如，设置深睡期的优先级高于浅睡期，在检测到深睡期以及浅睡期时，控制空调器按照深睡期对应的运行参数运行。
本实施例中，也可预先设置用户的优先级，以在空调器所在环境有多个用户处于睡眠状态，且多个用户处于不同的睡眠阶段时，控制空调器按照优先级最高的用户所在的睡眠阶段对应的运行参数运行。其中，用户预先与空调器进行绑定操作，在绑定操作的过程中，雷达传感器获取并记录用户的呼吸频率，并为用户创建用户信息，用户信息包括优先级。比如设置家中老年人的优先级最高，小孩子其次，成年人的优先级最低，在室内同时存在老年人、成年人以及小孩子时，优先以老年人所在的睡眠阶段对应的运行参数运行。
在第四实施例中，在获取到多个睡眠阶段对应的运行参数时，获取睡眠阶段的优先级，并控制空调器按照优先级最高的睡眠阶段对应的运行参数运行。这样，保证了空调器的有序调节。
在第五实施例中，如图6所示，在上述图2至图5所示的实施例基础上，所述实时或定时通过雷达传感器获取用户的运动幅度变化率的步骤包括：
步骤S11、实时或定时通过所述雷达传感器获取所述用户与所述空调器之间的距离；
步骤S12、根据所述距离获取所述用户的运行幅度变化率。
本实施例中，空调器上设置雷达传感器，并由雷达传感器实时或定时获取用户与空调器之间的距离，以根据距离获取用户的运行幅度变化率。
具体地，计算本次获取到的距离与上次获取到的距离之间的差值，将该差值作为用户的运动幅度，并计算该差值与上次获取到的距离之间的商值，将该商值作为运动幅度变化率。
在第五实施例中，实时或定时通过雷达传感器获取用户与空调器之间的距离，并根据距离获取用户的运行幅度变化率。这样，实现根据运行幅度变化率确定用户所处的睡眠阶段。
在第六实施例中，如图7所示，在上述图2至图6所示的实施例基础上，所述根据所述距离获取所述用户的运行幅度变化率的步骤包括：
步骤S121、计算本次获取到的距离与上次获取到的距离之间的差值，将所述差值作为所述用户的运动幅度；
步骤S122、根据所述运动幅度与上次获取到的距离计算所述运动幅度变化率。
本实施例中，空调器上设置雷达传感器，并由雷达传感器实时或定时获取用户与空调器之间的距离，以根据距离获取用户的运行幅度变化率。
具体地，计算本次获取到的距离与上次获取到的距离之间的差值，将该差值作为用户的运动幅度，并计算该差值与上次获取到的距离之间的商值，将该商值作为运动幅度变化率。比如，三次获取到的距离分别为80cm、90cm以及110cm，那么运动幅度为10cm、20cm（运动幅度取绝对值），运动幅度变化率为10/80=0.125、10/90=0.222。
需要说明的是，运动幅度变化率不限于上述计算方法，可根据实际情况进行设置。
在第六实施例中，计算本次获取到的距离与上次获取到的距离之间的差值，并根据差值与上次获取到的距离计算运动幅度变化率。这样，实现根据运行幅度变化率确定用户所处的睡眠阶段。
在第七实施例中，如图8所示，在上述图2至图7所示的实施例基础上，所述将所述差值作为所述用户的运动幅度之后，还包括：
步骤S123、判断所述运动幅度是否小于预设运动幅度；
步骤S124、在所述运动幅度小于所述预设运动幅度时，则执行所述根据所述运动幅度与上次获取到的距离计算所述运动幅度变化率的步骤。
本实施例中，在运动幅度小于预设运动幅度时，则判定用户处于睡眠状态，此时获取运行幅度变化率，以根据运行幅度变化率获取用户的睡眠阶段。
在第七实施例中，在运动幅度小于预设运动幅度时，则计算运动幅度变化率，这样，减轻了空调器或者服务器的计算负担。
在第八实施例中，如图9所示，在上述图2至图8所示的实施例基础上，所述实时或定时通过雷达传感器获取用户的运动幅度变化率之前，还包括：
步骤S50、判断所述用户是否处于睡眠状态；
