在本公开示例性实施例中，智能门锁的控制设备可以为第一终端、第二终端、云平台以及智能门锁。
下面将结合附图，对本公开示例性实施例中的技术方案进行清楚、完整地描述。
示例性实施例一
本公开示例性实施例提供了一种智能门锁的控制方法，其应用于智能门锁，智能门锁分别与云平台，以及第一终端进行通信。图2-1为根据本公开示例性实施例的一种智能门锁控制方法的实现流程示意图一，如图2-1所示，在本公开的示例性实施例中，智能门锁的控制方法可以包括以下步骤：
步骤201、接收云平台发送的门锁控制信息，门锁控制信息构造为控制智能门锁的使用权限。
在本公开示例性实施例中，智能门锁分别与云平台、第一终端进行通信，实现信息交互。这里，在云平台基于与租客客户端(第一终端)和房东客户端(第二终端)进行信息交互，得到用于控制智能门锁的使用权限的门锁控制信息后，该云平台就可以发送门锁控制信息给智能门锁，供该智能门锁基于该门锁控制信息进行门锁控制了。
需要说明的是，随着万物互联时代的到来，物联网的概念在全球范围内迅速被认可，并成为新一轮科技革命和产业革命的核心驱动力，巨大的应用市场推动全球范围内广域网连接技术出现爆发式增长。运营商为了更好的支撑物联网发展，不断优化网络能力。运营商通过核心网侧部署物联网专用设备，以及在业务侧建立独立的物联网管理和应用平台，提供面向物联网的连接服务能力。 众多运营商都已加速布局基于蜂窝的窄带物联网(Narrow Band Internet of Things，NB-IoT)技术。
为了提升智能门锁的安全和效率，本公开示例性实施例基于在智能门锁中安装NB模组，提出了一种利用NB-IoT技术低功耗、穿透强的特性，进行安全可靠的智能门锁密码控制的方法。
需要说明的是，可以实现本公开示例性实施例的其他通信方式也可被使用，本公开不作限制。
下面以NB-IoT技术为例，进行说明。
图3为根据本公开示例性实施例的智能门锁管理系统的拓扑结构图，如图3所示，本公开示例性实施例提出的智能门锁管理系统可以包括云平台，其支持NB-IoT规范，基于NB-IoT技术的云平台通过移动核心网与外部互联网互连，以此实现第一终端、第二终端和云平台的通信。进一步地，智能门锁管理系统还包括基站和集成有NB模组的智能门锁，其中，基站构造为实现云平台和智能门锁的通信；智能门锁具有基本的密码开锁功能，密码可以动态被更新，且智能门锁可以和第一终端进行无线通信。
需要说明的是，在本公开的示例性实施例中，智能门锁和云平台基于NB-IoT网络进行通信，智能门锁接收云平台通过NB-IoT网络发送的门锁控制信息，以实现对智能门锁使用权限的控制。利用NB-IoT技术，减少了网络信息传递的中转点，实现了端到端的传输。
进一步地，智能门锁在接收云平台发送的门锁控制信息时，为保证云平台和智能门锁之间状态的一致性，智能门锁可以采用心跳保活机制接收所述云平台发送的门锁控制信息。具体地，智能门锁定时给云平台发送一个数据包(心跳包)，告知云平台智能门锁自身处于连接状态，以此来确保智能门锁和云平台连接的有效性。
步骤202、基于门锁控制信息，确定智能门锁启动时，生成门锁密码。
在本公开的示例性实施例中，基于智能门锁和云平台的连接，智能门锁在接收到云平台发送的门锁控制信息后，根据门锁控制信息生成门锁密码。
需要说明的是，在本公开示例性实施例中，智能门锁根据云平台发送的门锁控制信息对应生成门锁密码，即当云平台发送的门锁控制信息不变时，门锁 密码也不会改变；当云平台发送的门锁控制信息改变时，门锁密码也随之改变。
步骤203、采用门锁密码进行锁定。
在本公开示例性实施例中，智能门锁在生成门锁密码之后，会将门锁密码更新设置到智能门锁中，以实现对智能门锁的锁定。
需要说明的是，在本公开示例性实施例中，第二终端通过云平台发送控制信息给智能门锁，使得第二终端能远程控制智能门锁，这提升了智能门锁控制的便利性。
步骤204、发送门锁密码给第一终端。
在本公开示例性实施例中，智能门锁在更新门锁密码之后，将门锁密码发送给第一终端，由此避开了云平台管理密码，实现了智能门锁对第一终端的直接控制。
需要说明的是，智能门锁在发送门锁密码给第一终端时，可基于无线网络协议发送，也可以是通过短消息发送来加强数据传输的安全性。进一步地，在本公开示例性实施例中，可以采用NB-IoT智能密码锁中的NB模组，将门锁密码基于SIM NB-IoT通信以短消息的形式发送到第一终端。
需要说明的是，在通过SIM NB-IoT进行发送时，为避免信号屏蔽，在设计智能门锁和NB-IoT通信模组集成时，可以安装天线以加强信号的传递。
本公开示例性实施例提供了一种智能门锁的控制方法，其应用于智能门锁中，智能门锁根据云平台发送的控制信息，在智能门锁中生成密码，并通过智能门锁将密码发给第一终端，避免了通过云平台来转发门锁密码至智能门锁和第一终端的复杂过程，减少了密码传输中转，实现了端到端的传输，且通过在智能门锁中生成门锁密码，有效地提高了智能门锁远程控制的安全性。
进一步地，如图2-2所示，图2-2为根据本公开示例性实施例的一种智能门锁控制方法的实现流程示意图二，在步骤202之后，本公开示例性实施例提供的一种智能门锁控制方法还包括步骤202A；以及，在步骤203之后且在步骤204之前，本公开示例性实施例提供的一种智能门锁控制方法还包括步骤203A。
步骤202A、根据门锁时效信息，设置门锁密码对应的解锁时效。
在本公开示例性实施例中，智能门锁在接收到云平台发送的门锁控制信息后，会基于门锁控制信息，在确定智能门锁启动时，生成门锁密码。
在本公开示例性实施例中，门锁控制信息可以包括：门锁时效信息。智能门锁在收到带有门锁时效信息的门锁控制信息后，会将门锁时效信息设置到智能门锁中，以此来设置与门锁密码对应的解锁时效。
需要说明的是，在本公开的示例性实施例中，门锁时效信息构造为控制第一终端对智能门锁的使用时限，门锁时效信息的格式在本公开中不做具体限制。具体地，门锁时效信息可以以时间戳和使用时长的形式存在，如时间戳信息为2018年6月1日，使用时长为二年；或者门锁时效信息以具体使用时间段形式存在，如2018年6月1日至2020年6月1日。
进一步地，在本公开示例性实施例中，云平台发送的门锁控制信息中的门锁时效信息，可以通过令牌Token的方式发送。Token更通俗点的解释可以称之为暗号，在一些数据传输之前，要先进行暗号的核对，不同的暗号被授权不同的数据操作。因此，智能门锁在获取Token后，需要先对其进行解码，以获取门锁时效信息。智能门锁在解码获得门锁时效信息后，设置门锁密码对应的解锁时效，从而实现智能门锁密码的动态管理。
步骤203A、采用门锁加密密钥对门锁密码进行加密，得到加密门锁密码。
在本公开示例性实施例中，智能门锁采用门锁密码锁定后，对门锁密码进行加密获取加密门锁密码。具体地，智能门锁在接收云平台发送的门锁控制信息中可以包括：门锁加密密钥。智能门锁利用门锁加密密钥对智能门锁进行加密得到加密门锁密码。
进一步地，在本公开的示例性实施例中，智能门锁和云平台可以基于NB-IoT网络进行通信连接。需要说明的是，加密门锁密码的生成依赖云平台和智能门锁间的通信，NB-IoT网络虽然有一定的时延，但考虑到设定密码过程对实时性要求并不高，所以不会影响用户体验。
在本公开示例性实施例中，基于步骤203A的实现，步骤204的过程可以为智能门锁发送加密门锁密码给第一终端。进一步地，可以采用NB-IoT智能密码锁中的NB模组，将加密门锁密码基于SIM NB-IoT通信以短消息的形式发送到第一终端。
图4为根据本公开示例性实施例的集成了NB模组的智能门锁系统结构图，在本公开示例性实施例中，如图4所示，NB模组和智能门锁集成到一起，可 进行信息交互。NB-IoT智能密码锁由三部分构成，包括：锁体部分、密码模块、NB模组。云平台包括：Token管理模块和密钥管理模块。第二终端(房东客户端)，具备门锁及时效选择功能。通过在第二终端上选择门锁身份标识(Identity，ID)进行时效设置，云平台的Token管理模块生成Token，并将生成的Token和密钥管理模块收到的门锁加密密钥作为门锁控制信息通过NB-IoT网络一起发送给智能门锁，智能门锁在收到门锁控制信息后，解码Token，获取门锁时效信息，并更新门锁密码至密码模块，同时智能门锁采用加密密钥加密门锁密码并发送加密后的加密门锁密码给第一终端，由此完成图2-2的步骤201-204中的具有时效性的门锁密码设置以及非明文密码的发送。
可以理解的是，在本公开示例性实施例中，智能门锁发送带有时效性的加密门锁密码给终端，能实现智能门锁动态单向设置非明文密码，从而在最大限度上降低密码泄露风险。对目前主流智能门锁采用指纹、虹膜以及固定密码等开锁方式进行了安全方面的补充，极大丰富了智能门锁的应用场景。
进一步地，如图2-3所示，图2-3为根据本公开示例性实施例的一种智能门锁控制方法的实现流程示意图三，在步骤204之后，本公开示例性实施例提供的一种智能门锁控制方法还可以包括步骤205-209，如下：
步骤205、接收第一终端发送的解锁请求，解锁请求中携带有解锁密码。
在本公开示例性实施例中，在智能门锁发送门锁密码给第一终端后，智能门锁会收到第一终端携带有解锁密码的解锁请求。
需要说明的是，在本公开示例性实施例中，智能门锁接收第一终端的解锁请求的方式可以包括：接收第一终端，即租客客户端发送的解锁请求；或接收第一终端通过近场通信(Near Field Communication，NFC)方式发送的解锁请求；或接收第一终端蓝牙芯片发送的解锁请求。
进一步地，当智能门锁给第一终端发送的是加密门锁密码时，智能门锁需要先对加密门锁密码进行解密来获得解锁密码。其中，解密过程在第一终端中完成，通过采用与加密密钥对应的解密密钥对加密门锁解密获得解锁密码。
步骤206、当解锁密码在解锁时效内时，利用解锁密码进行解锁。
在本公开示例性实施例中，智能门锁在收到第一终端的解锁密码请求后，先判断解锁密码是否在解锁时效内，当解锁密码在解锁时效内时，才利用解锁 密码进行解锁。
具体地，判断解锁密码是否在时效内，是根据智能门锁收到解锁密码请求的当前时间来判断解锁密码是否在解锁时效内。其中，智能门锁收到解锁密码的当前时间可以是解锁请求中携带的时间戳，也可以是智能门锁中记录的当前时间。
示例性的，智能门锁收到解锁密码请求的当前时间是2017年2月1号，而如步骤202A中设置的解锁时效是2016年6月1号至2018年6月1号，则解锁密码在解锁时效内。
具体地，当解锁密码在解锁时效内时，智能门锁利用解锁密码进行解锁的具体解锁过程是：智能门锁判断解锁密码是否与门锁密码一致，当一致时，智能门锁解锁成功；当解锁密码与门锁密码不一致时，解锁失败，智能门锁保持锁定。
步骤207、反馈智能门锁的解锁状态给第一终端；其中解锁状态包括解锁成功或解锁失败。
在本公开示例性实施例中，当解锁密码在解锁时效内时，利用解锁密码进行解锁。智能门锁匹配解锁密码与门锁密码是否一致，并将解锁状态反馈给第一终端。通过状态反馈，方便第一终端即时掌握解锁请求状态。
步骤208、当解锁密码未在解锁时效内时，保持锁定。
在本公开示例性实施例中，智能门锁在收到第一终端的解锁密码请求后，先判断解锁密码是否在解锁时效内，当解锁密码不在解锁时效内时，智能门锁保持锁定。其中，智能门锁收到解锁密码的当前时间可以是解锁请求中携带的时间戳，也可以是智能门锁中记录的当前时间。
具体地，如智能门锁记录收到解锁密码请求的当前时间是2023年2月1号，而如步骤202A中设置的解锁时效信息中，时间戳信息为2018年6月1日，使用时长为二年，则解锁密码不再解锁时效内。
需要说明的是，在本公开示例性实施例中，当解锁密码不在解锁时效内时，解密密码失效，智能门锁保持锁定。
步骤209、发送时效提醒给第一终端。
本公开示例性实施例中，当智能门锁判断出解锁密码不在解锁时效内后， 智能门锁向第一终端反馈时效提醒。
进一步地，在本公开示例性实施例中，时效提醒可以是基于SIM NB-IoT通信以短消息的形式发送，也可以是基于无线通信来发送。通过时效提醒，方便第一终端即时获知当前的租赁状态。
可以理解的是，在本公开示例性实施例中，通过智能门锁反馈解锁结果给第一终端，提高了智能门锁的管理效率。

需要说明的是，在本公开的示例性实施例中，第一终端支持加密算法和密钥管理功能，第一终端在与云平台建立连接后，与云平台协商加密方法，并在第一终端中生成密钥。
具体地，第一终端和云平台可以协商采用非对称加密算法或对称加密算法。其中，非对称加密算法是在加密和解密过程中采用不同的密钥，包括公开密钥(publickey)和私有密钥(privatekey)。公开密钥与私有密钥是一对，如果用公开密钥对数据进行加密，只有用对应的私有密钥才能解密；如果用私有密钥对数据进行加密，那么只有用对应的公开密钥才能解密。采用对称加密算法时，公钥和私钥为同一个密钥。需要说明的是，本公开示例性实施例中，非对称加密算法和对称加密算法为常规算法，本公开不再赘述。
进一步地，在本公开示例性实施例中，因非对称加密体系不要求通信双方事先传递密钥或有任何约定就能完成保密通信，并且密钥管理方便，可实现防 止假冒和抵赖，适合网络通信中的保密通信要求。相对于对称加密算法，其安全性能更优。因此，在本公开示例性实施例中，第一终端与云平台协商采用非对称加密算法生成对应的公钥和私钥。

进一步地，如图5-2所示，图5-2为根据本公开示例性实施例的一种智能门锁控制方法实现流程示意图二，在步骤304之后，本公开示例性实施例提供的一种智能门锁控制方法还可以包括步骤305-306，如下：
步骤305、向智能门锁发送解锁请求，解锁请求中携带有解锁密码。
在本公开示例性实施例中，第一终端在采用门锁解密密钥解密加密门锁密码获得解锁密码后，向智能门锁发送携带有解锁密码的解锁请求。
示例性的，第一终端在向智能门锁发送解码请求时，可以通过租客客户端界面上显示的开锁密码、或通过NFC、蓝牙等方式向智能门锁发送解锁请求。
步骤306、接收智能门锁反馈的解锁结果；其中解锁结果包括时效提醒或解锁状态。
在本公开示例性实施例中，第一终端在向智能门锁发送解码请求后，会收到智能门锁反馈的解锁结果。具体地：

进一步地，云平台在发送门锁控制信息给智能门锁时，为保证云平台和智能门锁之间状态的一致性，云平台也可以采用心跳保活机制发送门锁控制信息。具体地，云平台定时接收智能门锁发送的数据包(心跳包)，同时，云平台在接收到数据包后，告知智能门锁已经收到了数据包，以此来确保云平台和智能门锁之间的状态一致。
需要说明的是，在本公开示例性实施例中，云平台在每次收到第二终端的控制指示时，会依据控制指示生成具有时效性的控制信息并发送给智能门锁，以此实现对智能门锁的动态控制。

基于上述图7-图9所述的方法，示例性的，为加强网络的安全性，在本公开示例性实施例中，智能门锁中含有NB-IoT模组，云平台支持NB-IoT规范，将上述智能门锁、云平台、第一终端、第二终端组成的系统称为智能门锁管理系统，下面以基于NB-IoT技术的智能门锁管理系统为例，进行说明。
图10为根据本公开示例性实施例的一种智能门锁控制方法的交互流程示意图三，如图10所示，在本公开的示例性实施例中，智能门锁、云平台、第一终端和第二终端实现远程控制的方法可以包括以下步骤：
步骤1001、第二终端向云平台发送门锁控制指示；其中控制指示中包括门锁ID、门锁使用时效。
步骤1002、云平台根据门锁控制指示，生成令牌Token。
步骤1003、第一终端向云平台发起门锁控制请求，建立连接。
需要说明的是，在本公开示例性实施例中，第一终端向云平台发起门锁控制请求，是指租客通过租客客户端向云平台发起门锁控制请求。租客需要事先在第一终端进行注册，以获取对应智能门锁的操作权限。
步骤1004、第一终端和云平台协商采用非对称加密算法。
步骤1005、第一终端中生成公钥和私钥。
步骤1006、第一终端向云平台发送公钥和令牌Token。
步骤1007、云平台基于NB-IoT网络将公钥和Token发送给智能门锁，其中，云平台和智能门锁之间增加了心跳保活机制。
步骤1008、智能门锁解码Token，获取门锁时效信息，并将门锁时效信息设置到智能门锁中，同时，智能门锁更新门锁密码。
根据具有时效性的Token，触发生成门锁密码，并将门锁密码更新设置到智能门锁中，从而实现智能门锁密码动态设置的功能。
智能门锁中设置的门锁时效信息构造为限制门锁密码的解锁时效。
步骤1009、智能门锁采用公钥对门锁密码加密，生成加密门锁密码。
步骤1010、通过SIM NB-IoT通信以短消息的形式将加密门锁密码发送给第一终端。
步骤1011、第一终端用私钥对加密门锁密码解密，获取解锁密码。
步骤1012、第一终端向智能门锁发送携带有解锁密码的解锁请求。
步骤1013、智能门锁验证解锁密码的时效性。
智能门锁在收到解锁密码时，先根据步骤1008中的解锁时效来判断解锁密码是否在时效期内。
若解锁密码不在时效期内，说明第一终端已经没有权限使用智能门锁，解锁密码失效。智能门锁反馈时效提醒给第一终端。
若解锁密码在时效期内，说明第一终端有权限使用智能门锁，继续执行后续步骤。
步骤1014、智能门锁验证解锁密码与门锁密码是否匹配。
进一步地，本公开示例性实施例中，若是将门锁密码写到了NFC中，用户 可将手机NFC放入门锁NFC模块可感应范围。智能门锁读取手机NFC中存取的门锁密码，读取成功则继续进行密码验证。
如果解锁密码和门锁密码可以匹配，则智能门锁进行解锁操作；否则智能门锁保持锁定。
智能门锁反馈解锁成功或解锁失败的解锁状态给第一终端。
本公开示例性实施例提供了一种智能门锁控制方法，上述智能门锁的控制方法应用于配置有NB-IoT模组的智能门锁、支持NB-IoT规范的云平台以及支持加密算法和密钥管理功能的第一终端。图11为对应于本公开示例性实施例四中的第一终端获取智能门锁解锁密码过程的状态图。如图11所示，通过第二终端(房东客户端)输入时效给云平台，云平台生成门锁控制信息，并与第一终端协商加密算法，接收第一终端的公钥后，将具有时效性的Token和公钥发送给智能门锁。在云平台和智能门锁交互的过程中，增加了心跳保活机制来更新Token信息以保证云平台和智能门锁之间状态的一致性。智能门锁在收到公钥和Token信息以后，解码Token，在智能门锁中设置门锁密码和对应的解锁时效，并将加密门锁密码以短信的形式发送到第一终端。首先，本公开示例性实施例利用NB-IoT技术，减少了网络信息传递的中转点；其次，本公开示例性实施例利用由智能门锁动态单向设置非明文密码，且采用非对称加密算法加密，从而在最大限度上降低密码泄露风险，对目前主流智能门锁采用指纹、虹膜以及固定密码等开锁方式进行了安全方面的补充，极大丰富了智能门锁的应用场景。
