具体实施方式
为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请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申请一部分的实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本申请保护的范围。
需要说明的是，本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下能够互换，以便这里描述的本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是允许包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
为便于用户理解本申请，下面对本申请各实施例中涉及到的部分术语或名词做出解释：
微波雷达传感器，通过发射毫米波信号来检测目标对象，微波雷达传感器使用毫米波，毫米波是指30G至300GHz频域的电磁波。与摄像头、红外、激光等光学传感器相比，毫米波雷达穿透雾、烟、灰尘的能力强，抗干扰能力强，具有全天候全天时的特点。
多普勒频偏，也叫多普勒频移，当微波雷达设备以恒定的速率向某一方向发送电磁波时，由于传播路程的原因，会造成相位和频率的变化。物体辐射的波长因为波源和预设人体的相对运动而产生变化，当运动的波源前面，波被压缩，波长变得较短，频率变得较高，当运动在波源后面时，会产生相反的效应，波长变得较长，频率变得较低。
根据本申请实施例，提供了一种人体活动姿态的监测方法实施例，需要说明的是，在附图的流程图示出的步骤能够在诸如一组计算机可执行指令的计算机系统中执行，并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，也以不同于此处的顺序执行所示出或描述的步骤。
本申请实施例中的微波雷达技术通过放射出一定频率的电磁波，并检测回波的多普勒频偏，再计算得出人体的具体姿态。利用微波雷达技术具有良好的穿透性，对浴室这种水雾浓度较大的环境也能很好地检测人体活动姿态，且不会采集用户的图像等个人信息，很好的保护了用户的隐私。下面通过各个步骤来详细说明本申请实施例。
图1是根据本申请实施例的一种人体活动姿态的监测方法的流程图，如图1所示，该方法包括如下步骤：
步骤S102，接收微波检测信号，其中，微波检测信号是对目标区域进行微波扫描后得到的检测信号；
步骤S104，根据微波检测信号，判断目标区域内预设人体的当前活动姿态是否处于危险姿态的范围，其中，当前活动姿态为预设人体在当前时间点所处位置的动作形态；
步骤S106，在目标区域内预设人体的当前活动姿态处于危险姿态的范围时，发出报警 信号。
通过上述步骤，在一些实施方式中，采用接收微波检测信号，其中，微波检测信号是对目标区域进行微波扫描后得到的检测信号，根据微波检测信号，判断目标区域内预设人体的当前活动姿态是否处于危险姿态的范围，其中，当前活动姿态为预设人体在当前时间点所处位置的动作形态，在目标区域内预设人体的当前活动姿态处于危险姿态的范围时，发出报警信号。在该实施例中，利用微波雷达设备(例如微波雷达传感器等)发出的微波信号具有良好的穿透性，对浴室这种水雾浓度较大的环境进行有效监测，对人体的活动姿态进行监测，监测用户是否出现危险状态，在确定出现危险姿态时，在一些实施方式中通过报警信号来告知相应人员，监测数据较为准确，且能够及时通知其它用户监测结果，保障用户安全，从而解决关技术中无法监测雾气浓度较大的活动环境，导致无法确定用户是否处于危险状态的技术问题。
本申请实施例中涉及的微波是指通过微波雷达设备(例如，微波雷达传感器)发出的毫米波雷达信号。在一些实施例中，微波雷达设备为毫米波雷达、微波雷达、微波光电雷达，具有微波制导和光电制导的特点。本申请实施例并不限定微波雷达设备的类型和具体型号，能够根据每个监测区域、工作区域设置不同数量、不同类型的微波雷达设备。
上述微波雷达设备能够发送微波雷达信号，并接收微波雷达检测信号，对需要检测的目标区域进行扫描，扫描时间和扫描速度能够根据目标区域的大小自行设置。
在一些实施例中，该微波雷达设备预先与中控终端建立通讯连接，在检测完成后，将检测结果通过各种网络(如局域网、广域网等)发送至中控终端，用户能够通过中控终端查询检测结果。
下面对上述各步骤进行详细说明。
步骤S102，接收微波检测信号，其中，微波检测信号是对目标区域进行微波扫描后得到的检测信号。
在本申请实施例中，接收微波检测信号的步骤，包括：通过预设的微波雷达设备按照预设扫描规则对目标区域的各个子区域进行扫描；基于扫描结果确定目标区域中预设人体的当前位置；微波雷达设备持续扫描当前位置和预设人体，得到预设时长(在一些实施方式中，该预设时长是指每次扫描的时长，例如，微波雷达设备在发出三次电磁波，接收三次回波的多普勒频偏信号时的时长)的微波检测信号；接收微波雷达设备发送的预设时长的微波检测信号。
在一些实施方式中，对于微波雷达设备的安装位置和安装数量，根据目标区域的大小，及各个子区域的大小自行设置。在安装完成后，且连接中控终端后，通过微波雷达设备先 扫描各个子区域，以确定在目标区域中是否有人体活动，并在有人体活动时，准确确定当前人体所在的位置，后续按照预设间隔时间扫描该位置和人体，以得到微波检测信号，从而基于微波检测信号判断人体在该目标区域中的实时活动姿态。
在一些实施方式中，对于上述的目标区域中的各个子区域，是指微波雷达设备在整体扫描了目标区域后，依据微波雷达设备每次能够扫描的范围大小对目标区域进行分割，得到多个子区域，这样，每个子区域都扫描一次或多次，为后续准确的确定预设人体的当前位置做准备。
在一些实施例中，对于上述基于扫描结果确定目标区域中预设人体的当前位置，是微博雷达设备的控制自动分析确定预设人体的当期位置，或微博雷达设备将扫描结果发送至预设的处理设备(例如中控终端或者服务器)，通过该预设的处理设备分析得到的。
作为本申请一实施例，微波雷达设备持续扫描当前位置和预设人体，得到预设时长的微波检测信号的步骤，包括：微波雷达设备持续向当前位置和预设人体放射出预设频率的电磁波；微波雷达设备检测回波的多普勒频偏，得到预设时长的微波检测信号，其中，使用多普勒频偏计算出预设人体的当前活动姿态。
即通过微波雷达设备发送一定频率的电磁波，以扫描当前位置和预设人体，并检测回波的多普勒频偏，利用一定的算法计算得出人体的活动姿态。
步骤S104，根据微波检测信号，判断目标区域内预设人体的当前活动姿态是否处于危险姿态的范围，其中，当前活动姿态为预设人体在当前时间点所处位置的动作形态。
作为本申请一实施例，根据微波检测信号，判断目标区域内预设人体的当前活动姿态是否处于危险姿态的范围的步骤，包括：解析微波检测信号，得到预设时长内各个时间点预设人体的当前活动姿态；比较各时间点预设人体的当前活动姿态，确定姿态变化幅度；基于姿态变化幅度和预设数据库中的危险参考姿态，判断目标区域内预设人体的当前活动姿态是否处于危险姿态的范围。
即对微波雷达设备采集到的相关数据(微波检测信号)进行处理，经过计算和对比，得到目标区域内预设人体的当前活动姿态是否达到危险姿态。
在一些实施例中，危险姿态包括但不限于：滑倒姿态、跌倒姿态、绊倒姿态、碰撞物体姿态。在另一些实施例中，该危险姿态是预设时长内的变化姿态，例如，预设人体在10内由站立到倒地，此时判断为滑倒姿态/跌倒姿态。
步骤S106，在目标区域内预设人体的当前活动姿态处于危险姿态的范围时，发出报警信号。
作为本申请一实施例，在目标区域内预设人体的当前活动姿态处于危险姿态的范围 时，发出报警信号的步骤，包括：控制微波雷达设备的报警模块发出报警信号，其中，微波雷达设备用于目标区域进行微波扫描，得到微波检测信号；或者，在微波雷达设备与预设人体持有的通讯设备处于同一局域网内时，将报警信号发送至通讯设备；或者，在微波雷达设备与预设人体持有的通讯设备不处于同一局域网内时，将报警信号发送至云端服务器，并通过云端服务器将报警信号下发至通讯设备，其中，云端服务器与微波雷达设备处于同一广域网内。
即在判断预设人体的当前活动姿态处于危险姿态的范围时，通过多种警报方式来通知相关用户，本申请实施例中示意性说明了三种警报方式。第一种，微波雷达设备自身发出报警信号，例如，发出报警铃声、红色灯光闪烁灯；第二种，若用户持有的通讯设备和微波雷达设备在同一局域网内，则微波雷达设备通过局域网直接将报警信号上传至通讯设备，在一些实施方式中，通讯终端的显示界面通过预设形式显示与当前危险姿态对应的危险信息；第三种，若用户持有的通讯设备和微波雷达设备不在同一局域网，而在同一广域网内，在一些实施方式中，通过广域网将报警信号上传至云端服务器，云端服务器通过广域网将报警信号下发至通讯设备。
另一种实施例，在发出报警信号之后，监测方法还包括：监测是否有警报解除指令；若监测到微波雷达设备接收到警报解除指令，则控制微波雷达设备的报警模块停止报警；若监测到预设人体持有的通讯设备接收到警报解除指令，则停止向通讯设备发送报警信号。
本申请实施例中，在解除警报时，也需要针对上述三种情况，进行不同的警报解除，第一种，直接向微波雷达设备下发警报解除指令，例如，直接关闭微波雷达设备的警报，例如，通过遥控器/按键等方式下发停止报警指令；第二种，通过局域网向通讯设备发送警报解除指令；第三种，通过广域网向通讯设备/微波雷达设备发送警报解除指令。在另一些实施例中，用户操控通讯设备向微波雷达设备发送警报解除指令，
在一些实施例中，在上述第一种方式中，向微波雷达设备端下发警报解除指令有两种形式，一是，微波雷达设备自身发现被检测区域不存在危险状态的人员，则下发警报解除指令；二是，通过一定人为操作向雷达波设备下发警报解除指令。
通过上述实施例，能够确定一种对用户活动姿态的监测方式，尤其是在家庭环境、澡堂环境、温泉环境等环境中，利用能够发送微波信号/毫米波信号的雷达设备监测人体的活动姿态，例如，监测家庭中的老人、小孩在无人看管的情况下的活动姿态，对人体是否跌倒、摔倒、发生磕碰等情况进行有效检测，在出现危险时，能够及时通过报警信号来告知相关人员，及时对监测人员进行救助，保障这些人的生命健康。
下面通过另一种人体活动姿态的监测方法来说明本申请。
该监测方法能够应用于浴室，适用于微波雷达设备(简称为雷达设备)，雷达设备与用户持有的手机连接。
图2是根据本申请实施例的另一种人体活动姿态的监测方法的流程图，如图2所示，该方法包括：
步骤S201，雷达设备处于工作状态，持续对待检测区域进行检测。在一些实施方式中，被检测区域为浴室，即利用雷达设备检测浴室中的人体姿态；
步骤S203，对雷达设备采集到的姿态检测信号进行处理，以确定被检测区域内人体是否跌倒；若未出现跌倒情况，则返回步骤S201。
步骤S205，若出现跌倒情况，自身警报响起；
步骤S207，若移动终端和雷达设备处于同一局域网内，通过局域网直接将警报指令上传给移动终端，移动终端通过预设形式进行跌倒提示；
步骤S209，若移动终端和雷达设备不处于同一局域网，通过广域网络将警报指令上传到云端，云端再通过广域网将警报指令下发给移动设备。
步骤S211，持续监测。
步骤S213，若雷达设备端有解除警报指令下发，关闭雷达设备端的警报，同时将警报解除指令通过局域网或广域网传输给移动终端，关闭移动终端的警报。
步骤S215，若移动终端有解除警报指令下发，关闭移动终端的警报，将警报解除指令通过局域网或广域网传输到雷达设备端，关闭雷达设备端的警报。
步骤S217，在未监测到有解除警报指令时，持续发出警报。
上述人体活动姿态的监测方法，能够对浴室等待检测区域的人体活动姿态进行有效监测，通过雷达设备检测待检测区域中的人体的活动姿态，在出现危险姿态时(如跌倒)，利用雷达设备，或移动终端，或雷达设备和移动终端共同发出警报信号，若接收到解除警报指令，能够解除雷达设备，移动终端，或雷达设备和移动终端的警报，根据具体情况，解除不同设备的警报，利用雷达设备的微波雷达技术具有良好的穿透性这一特性，实现对待检测区域的有效检测，快速、准确的实现检测。
