具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
请参考图1，图1为本发明实施例所提供的一种智能锁具的开锁认证方法 的流程图。该方法可以包括：
步骤101：在获取开锁请求后，确定当前的工作模式；其中，工作模式包括：一级安全工作模式和二级安全工作模式。
可以理解的是，本步骤中的工作模式可以为智能锁具进行解锁认证的工作模式，本步骤中的工作模式可以包含有不同安全级别对应的安全工作模式，如普通安全级别对应的二级安全工作模式和更高一级的安全级别对应的一级安全工作模式。本实施例中通过智能锁具中的处理器(如MCU，单片机)在获取开锁请求后，确定当前的工作模式，从而能够使处理器根据确定的当前的工作模式，选择对应安全级别的开锁认证方式进行开锁认证，实现不同安全级别的智能转换，提高智能锁具使用的灵活性。
具体的，对于本步骤中工作模式的具体数量和类型，可以由设计人员根据实用场景和用户需求自行设置，如工作模式可以包括适用于一般使用场景的与市面上的智能锁具的安全级别相同的普通安全级别对应的二级安全工作模式，即使用密码、语音和/或图像等解锁信息进行开锁认证的安全工作模式；以及适用于家中较长时间无人的使用场景的更高一级的安全级别对应的一级安全工作模式，即使用解锁信息和认证用户终端的解锁授权信息进行开锁认证的安全工作模式。工作模式还可以包括适用于人员流动较大的使用场景(比如有家庭聚会、或者家中经营某些业务会每天不定时有人员来往等)的较低安全级别对应的三级安全工作模式，和/或适用于人员流动不大且避免解锁信息的多次设置或泄露的较低安全级别对应的四级安全工作模式。本实施例对此不做任何限制。
对应的，对于本步骤中智能锁具中的处理器确定当前的工作模式的具体方式，即不同的工作模式之间的具体转换方式，可以由设计人员根据实用场景和用户需求自行设置，如智能锁具的不同的工作模式由用户通过认证用户终端或智能锁具上的控制设备(如按键或触摸屏)自行随意切换时，本步骤中智能锁具的处理器可以将获取的选择工作模式确定为当前的工作模式，即用户可以随时通过认证用户终端或智能锁具上的控制设备从多个不同的工作模式中选择一个工作模式作为之后智能锁具的工作模式，即本步骤中确定的当前的工作模式；智能锁具的不同的工作模式由智能锁具的处理器自行智能切换时，本步骤中处理器可以根据预设的智能切换规则，确定当前的工作模 式；智能锁具的不同的工作模式由用户自行随意切换和处理器自行智能切换时，本步骤中处理器可以先判断是否获取了选择工作模式，若获取了选择工作模式则将获取的选择工作模式确定为当前的工作模式，若未获取选择工作模式则根据预设的智能切换规则，确定当前的工作模式。本实施例对此不做任何限制。
具体的，对于上述处理器根据预设的智能切换规则，确定当前的工作模式的具体方式，即智能切换规则的具体设置，可以由设计人员或用户根据实用场景和用户需求自行设置，如智能切换规则可以为智能锁具默认工作在一级安全工作模式，当智能锁具检测到用户通过认证用户终端发送的二级安全工作模式的短时授权指令时，在短时间(即第一预设时间段，如10min)内切换到二级安全工作模式，之后再返回一级安全工作模式；即本步骤可以包括判断前第一预设时间段内是否接收到认证用户终端发送的二级安全工作模式的短时授权指令；若是，则确定当前的工作模式为二级安全工作模式；若否，则确定当前的工作模式为一级安全工作模式。智能切换规则也可以为智能锁具默认工作在二级安全工作模式，当智能锁具检测到较长时间(即第二预设时间段，如24h)内一直未执行过开锁操作，即用户较长一段时间都没有开关锁的操作时，智能锁具可以自动切换到一级安全工作模式；即本步骤可以包括判断前第二预设时间段内是否执行过开锁操作；若是，则确定当前的工作模式为二级安全工作模式；若否，则确定当前的工作模式为一级安全工作模式。智能锁具的工作模式还包括三级安全工作模式和/或四级安全工作模式时，在上述两种智能切换规则的基础上还可以包括某固定的时间段(即第三预设时间段)内的工作模式设置，即在第三预设时间段内的时间智能锁具切换到对应的工作模式，第三预设时间段外的时间智能锁具按上述任一智能切换规则进行工作模式的切换，如智能锁具的工作模式包括一级安全工作模式、二级安全工作模式和三级安全工作模式，第三预设时间段对应的工作模式为三级安全工作模式且智能锁具默认工作在二级安全工作模式时，本步骤中处理器可以先判断当前是否处于第三预设时间段；若是，则确定当前的工作模式为三级安全工作模式，即第三预设时间段对应的工作模式为三级安全工作模式；若否，则执行上述判断前第二预设时间段内是否执行过开锁操作的步骤。本实施例对此不做任何限制。
需要说明的是，本步骤之前还可以包括智能锁具的处理器获取开锁请求的步骤。对于智能锁具的处理器获取开锁请求的具体方式，可以由设计人员根据实用场景和用户需求自行设置，如处理器可以在检测到智能锁具的预设按键或触摸屏的预设位置被按动或触摸后，生成开锁请求；处理器也可以在检测到用户输入在按键或触摸屏输入的密码后，生成开锁请求；智能锁具设置有用于检测门外人员的人员检测设备(如红外检测设备和摄像头等)时，处理器还可以在检测到门外有人或有人停留预设时间(如30s)时，生成开锁请求。本实施例对此不做任何限制。
步骤102：若当前的工作模式为一级安全工作模式，则获取解锁信息和认证用户终端的解锁授权信息，并根据解锁信息和解锁授权信息进行开锁认证；其中，解锁信息为智能锁具的解锁采集设备采集的用于开锁的数据。
可以理解的是，本步骤的目的可以为在确定当前的工作模式为一级安全工作模式时，在常规的利用解锁信息进行开锁认证的基础上加入对认证用户终端发送的解锁授权信息的开锁认证，使智能锁具必须每次经过认证用户终端的授权之后才能开锁，在该模式下，没有经过授权时任何人都打不开智能锁具，安全性更高，更适用于家中较长时间无人的使用场景。
其中，本步骤中的解锁信息可以为之智能锁具的解锁采集设备(如按键、触摸屏、摄像头、麦克风和短距离无线接收设备等)采集的用于开锁的数据，即现有技术中智能锁具的开锁认证所需的输入信息。对于解锁信息的具体内容可以由设计人员根据实用场景和用户需求自行设置，如解锁信息可以包括密码、语音和图像中的任意一项或多项。
具体的，对于本步骤中处理器获取智能锁具的解锁采集设备采集解锁信息的具体方式，可以由设计人员自行设置，如解锁信息包括密码、开锁语音指令和图像数据时，处理器可以接收智能锁具的按键、IC读卡器或触摸屏采集的密码、智能锁具的麦克风采集的开锁语音指令和智能锁具的摄像头采集的图像数据；处理器也可以直接获取智能锁具的短距离无线接收设备(如蓝牙设备)接收的用户终端(如手机)发送的密码、开锁语音指令和图像数据。本实施例对此不做任何限制。
需要说明的是，本步骤中的认证用户终端可以为与智能锁具进行了配对认证的用户终端(如手机)。本步骤中的解锁授权信息可以为认证用户终端 向智能锁具发送的是否允许本次开锁的信息，如解锁授权信息可以为解锁指令或禁止解锁指令。具体的，对于本步骤中处理器获取认证用户终端的解锁授权信息的具体方式，可以由设计人员自行设置，如处理器可以利用无线收发设备(如WIFI设备)通过无线网络向认证用户终端发送解锁授权请求；并接收认证用户终端通过无线网络返回的解锁授权信息；智能锁具设置有摄像头时，处理器也可以利用无线收发设备向认证用户终端发送解锁授权请求的同时，打开摄像头向认证用户终端发送摄像头采集的当前图像数据，使认证用户终端的用户可以查看当前的门前的环境，并根据门前的人是否是家中成员，确定是否可以授权打开智能锁具，返回相应的解锁授权信息。
对应的，对于本步骤中处理器根据解锁信息和解锁授权信息进行开锁认证的具体方式，可以由设计人员自行设置，如可以先根据解锁信息进行开锁认证，解锁信息认证通过后，再根据解锁授权信息进行开锁认证，在解锁授权信息开锁认证通过后，执行开锁操作；也可以同时对解锁信息和解锁授权信息分别进行开锁认证，在解锁信息和解锁授权信息均认证通过后，执行开锁操作。本实施例对此不做任何限制。
对应的，对于本步骤中根据解锁信息和解锁授权信息进行开锁认证的具体过程，可以由设计人员自行设置，如可以采用与现有技术中的解锁信息的开锁认证过程相同或相似的方式，对解锁信息进行开锁认证，如解锁信息包括智能锁具的麦克风采集的开锁语音指令和智能锁具的摄像头采集的图像数据时，可以对开锁语音指令进行语音识别和声纹识别，判断开锁语音指令是否与预设开锁指令和预设声纹数据均匹配；若均匹配再对图像数据进行人脸识别，判断人脸识别结果是否为匹配；若人脸识别结果为匹配，则确定解锁信息认证通过。解锁授权信息的进行开锁认证过程可以为判断解锁授权信息是否为解锁指令；若解锁授权信息为解锁指令，则确定解锁授权信息认证通过；若解锁授权信息不为解锁指令，即解锁授权信息为禁止解锁指令，则确定解锁授权信息认证不通过。
步骤103：若当前的工作模式为二级安全工作模式，则获取解锁信息，并根据解锁信息进行开锁认证。
可以理解的是，本步骤的目的可以为在确定当前的工作模式为二级安全工作模式时，智能锁具利用门前人员输入或自行采集的解锁信息进行常规的 开锁认证，避免在一般的使用场景下避免认证用户终端的加入，减少认证用户终端的授权次数，提高用户体验。
具体的，对于本步骤中获取解锁信息，并根据解锁信息进行开锁认证的具体方式，可以采用与步骤102中解锁信息的获取和开锁认证相同或相似的方式实现，本实施例对此不做任何限制。
需要说明的是，本实施例中智能锁具的工作模式还包括三级安全工作模式时，本实施例还可以包括若当前的工作模式为三级安全工作模式，则执行开锁操作的步骤，即当前的工作模式为三级安全工作模式时，处理器可以在获取开锁请求后，自动开锁，避免了用户频繁的开门。
对应的，本实施例中智能锁具的工作模式还包括四级安全工作模式时，本实施例还可以包括若当前的工作模式为四级安全工作模式，获取解锁授权信息，并根据解锁授权信息进行开锁认证。即当前的工作模式为四级安全工作模式时，处理器可以在每次获取开锁请求后，请求认证用户终端的解锁授权信息并进行开锁认证，使用户家中无人时，可以直接通过认证用户终端进行智能锁具的开锁控制，避免外人需知道智能锁具的密码才能进屋的情况，且每次开锁均由认证用户终端的用户控制，提高了安全性。
本实施例中，本发明实施例通过智能锁具在一级安全工作模式时，根据解锁信息和认证用户终端的解锁授权信息进行开锁认证，使得每次开锁均需用户授权，安全性更高，适用于家中较长时间无人的使用场景；通过在获取开锁请求后，确定当前的工作模式，使智能锁具可以完成一般使用场景和长时间无人的使用场景的智能切换，从而在保证智能锁具使用安全的同时，提高了使用场景的灵活性，提升了用户体验。
请参考图2，图2为本发明实施例所提供的另一种智能锁具的开锁认证方法的流程图。该方法可以包括：
步骤201：根据智能锁具的红外检测设备采集的红外信号，判断门外是否有人停留预设时间；若是，则进入步骤202。
可以理解的是，本步骤的目的可以为智能锁具中的处理器利用设置的红外检测设备(如红外传感器)确定门外是否有人停留预设时间，即确定是否有人要进入到屋内；从而在确定门外是否有人停留预设时间后，自动生成开 锁请求，并进入到步骤202进行接下来的开锁认证过程。
具体的，本步骤中智能锁具的处理器(如图3中的MCU)可以通过判断红外信号对应的距离值小于预设距离值的持续时间是否达到预设时间，从而确定门外是否有人停留预设时间，即在红外信号对应的距离值小于预设距离值的持续时间达到预设时间时，确定门外有人停留预设时间。
对应的，对于本步骤中门外没有人停留预设时间的情况，可以直接结束本流程。
步骤202：判断当前是否处于第三预设时间段；若是，则确定当前的工作模式为三级安全工作模式，并进入步骤203；若否，则进入步骤204。
可以理解的是，本实施例中的第三预设时间段可以为预先设置的三级安全工作模式对应的时间段，如每天的8:00到20:00。本实施例中智能锁具的工作模式可以包括一级安全工作模式、二级安全工作模式和三级安全工作模式。也就是说，如图4所示，本步骤的目的可以为在设置了第三预设时间段时，通过本步骤判断当前的工作模式是否处于三级安全工作模式；若是，则直接进入步骤203执行开锁操作，比如当用户在某一天要举行家庭聚会时，会有很多人频繁的来访，此时可以将智能锁具8:00到12:00设置为第三预设时间段，在该时间段内，任何来访者都可以开锁；若否，则进入步骤204确定当前的工作模式是一级安全工作模式还是二级安全工作模式。
对应的，本步骤之前还可以包括判断是否设置了第三预设时间段的步骤，若是，则进入本步骤；若否，则可以直接进入步骤204。
需要说明的是，本实施例是以智能锁具的一种智能锁具的处理器自行智能切换的不同的工作模式对应的开锁认证方法为例进行的展示，在本实施例的基础上还可以加入用户通过认证用户终端或智能锁具上的控制设备(如按键或触摸屏)自行随意切换不同的工作模式对应的开锁认证过程，如本步骤之前还可以包括判断是否存储有用户设置的选择工作模式的步骤；若否，则进入本步骤；若是，则将选择工作模式确定为当前的工作模式，并进入对应的步骤进行开锁认证。如选择工作模式为三级安全工作模式时，可以进入到步骤203；选择工作模式为一级安全工作模式时，可以进入到步骤205；选择工作模式为二级安全工作模式时，可以进入到步骤210。
步骤203：执行开锁操作。
可以理解的是，本步骤可以为智能锁具的处理器通过执行开锁操作，控制智能锁具中的机械锁开锁。
步骤204：判断前第二预设时间段内是否执行过开锁操作；若否，则确定当前的工作模式为一级安全工作模式，并进入步骤205；若是，则确定当前的工作模式为二级安全工作模式，并进入步骤211；
可理解的是，本步骤的目的可以为通过前第二预设时间段(如24h)内是否执行过开锁操作，确定家中是否较长时间处于无人状态，从而在前第二预设时间段内未执行过开锁操作，即家中较长时间处于无人状态时，确定当前的工作模式为一级安全工作模式，提高安全性；从而实现一级安全工作模式和二级安全工作模式之间的智能切换。
步骤205：获取智能锁具的麦克风采集的开锁语音指令和智能锁具的摄像头采集的图像数据。
可以理解的是，如图3和图4所示，本实施例中的智能锁具可以设置有麦克风(mic)和摄像头，从而在处理器(如图3中的MCU)确定当前的工作模式为一级安全工作模式时打开麦克风录取用户说出的开锁语音指令(即音频数据)，并打开摄像头拍照获取图像数据。
具体的，本实施例是以处理器控制麦克风和摄像头同时采集开锁语音指令和图像数据为例进行的展示，也可以先采集开锁语音指令或图像数据，待采集的开锁语音指令或图像数据认证通过后再采集另一种数据，本实施例对此不做任何限制。
步骤206：对开锁语音指令进行语音识别和声纹识别，判断开锁语音指令是否与预设开锁指令和预设声纹数据均匹配；若否，则进入步骤207；若是，则进入步骤208。
其中，本步骤的目的可以为处理器对麦克风采集的用户说出的开锁语音指令进行语音识别和声纹识别，例如假设预设开锁指令为“开锁”，处理器对麦克风采集的开锁语音指令进行语音识别和声纹识别，若语音识别到的开锁语音指令为“开锁”指令，且声纹识别的结果匹配到预先存储的用户的声纹数据(即预设声纹数据)，即采集到开锁语音指令的声纹与存储的声纹判断一致(为同一人)，确定开锁语音指令与预设开锁指令和预设声纹数据均匹配；否则，确定开锁语音指令不与预设开锁指令和预设声纹数据均匹配，可以直 接进入步骤207不执行开锁操作结束本次流程，也可以通过智能锁具的显示器或扬声器输出开锁语音指令匹配失败的提示信息并进入步骤207，以提示用户重新说出正确的开锁语音指令。
步骤207：不执行开锁操作。
具体的，本步骤的目的可以为在解锁认证不同的情况下，处理器不执行开锁操作，结束本次流程。
步骤208：对图像数据进行人脸识别，判断人脸识别结果是否为匹配；若是，则进入步骤209；若否，则进入步骤207。
其中，本步骤的目的可以为处理器对摄像头采集的图像数据进行人脸识别，当采集的图像数据中的人脸数据与预先存储的用户的人脸数据判断一致(为同一人)时，可以确定人脸识别结果为匹配，可以进入步骤209获取解锁授权信息。
具体的，对于本步骤中对图像数据进行人脸识别的具体方式，可以采用与现有技术中的人脸识别方法相同或相似的方式实现，本实施例对此不做任何限制。
步骤209：通过无线网络向认证用户终端发送解锁授权请求，并接收解锁授权请求对应的解锁授权信息。
具体的，如图4所示，本步骤之前还可以包括判断是否之前第一预设时间段内是否接收到认证用户终端(如图4中的手机)发送的短时开锁授权指令，即用户可以通过认证用户终端向智能锁具发送短时开锁授权指令，以在第一预设时间段内授权智能锁具在解锁信息认证通过便可以执行开锁操作。
对应的，如图4所示，本实施例中处理器利用无线通讯设备通过无线网络向认证用户终端发送解锁授权请求时，可以打开摄像头采集当前的环境录像(即当前图像数据)并发送到认证用户终端，使认证用户终端的用户可以查看当前的门前的环境，并根据门前的人是否是家中成员，判定是否可以授权打开智能锁具。
步骤210：判断解锁授权信息是否为解锁指令；若是，则进入步骤203；若否，则进入步骤207。
可以理解的是，本步骤通过判断解锁授权信息是否为解锁指令，确定用户是否通过认证用户终端授权智能锁具进行开锁操作，使得如果没有经过认 证用户终端的授权，智能锁具不会被任何人打开，即使解锁信息认证通过一致，由此可以防止有些不法分子对用户进行偷拍或者录音后进行开锁而导致的安全隐患。
步骤211：获取智能锁具的麦克风采集的开锁语音指令和智能锁具的摄像头采集的图像数据。
步骤212：对开锁语音指令进行语音识别和声纹识别，判断开锁语音指令是否与预设开锁指令和预设声纹数据均匹配；若否，则进入步骤207；若是，则进入步骤213。
步骤213：对图像数据进行人脸识别，判断人脸识别结果是否为匹配；若是，则进入步骤203；若否，则进入步骤207。
其中，步骤211至步骤213与步骤205、步骤206和步骤208相似，在此不再赘述。
可以理解的是，本实施例中通过智能锁具的工作模式可以包括普通安全级别的二级安全工作模式、更高一级的安全级别的一级安全工作模式和较为低级的安全级别的三级安全工作模式。普通安全级别可以等同于市面上的智能锁的安全级别，适用于一般场景；更高一级的安全级别，必须每次经过认证用户终端的授权之后才能开锁，在该模式下，没有经过授权任何人都打不开智能锁，安全性更高，更适用于家中较长时间无人的使用场景；较为低级的安全级别，适用于有人员流动较大的场景(比如有家庭聚会、或者家中经营某些业务会每天不定时有人员来往等)，当有人频繁来访时，只要在门口停留些许时间。智能锁具可以自动打开，不需要用户在去频繁的开门，使用更为灵活。本实施例通过这三个安全级别之间的工作模式的智能转换既保证了安全性，又提高了使用灵活性。
本实施例中，本发明实施例通过智能锁具的一级安全工作模式、二级安全工作模式和三级安全工作模式这三种工作模式的智能切换，使智能锁具能够切换到不同的防护等级，能够在保证智能锁具的使用安全性的基础上，令使用场景更加灵活，提升用户体验。
