Description
本申请要求于2020年8月31日提交国家知识产权局、申请号为202010899646.3、申请名称为“一种数据传输方法及电子设备”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
本申请涉及物联网技术领域,尤其涉及一种数据传输方法及电子设备。
现实生活中存在大量需要将一个设备的数据传输到另一个设备的场景。例如,更换新设备时,需要将旧设备中的配置信息等发送到新设备中。又例如,新购入多个相同型号的IoT设备时,需要将其中已设置好的IoT设备的配置信息克隆到其他的IoT设备上。
目前,一般需要依赖第三方设备(例如安装有克隆应用软件的设备,或网关设备,或服务器)完成两个设备之间的数据传输。具体地,发送数据的设备先与第三方设备建立连接,将待发送的数据发送给第三方设备。然后,第三方设备与接收数据的设备建立连接,在将待发送的数据转发给接收数据的设备。由此可见,用户需要在多个设备上进行多次的连接、数据的导出和导入,操作繁琐。另外,当待传输的数据为配网信息、设备的配置信息以及用户数据等敏感数据时,将待传输的数据导出并缓存在第三方设备上存在泄漏风险。

图1为本申请实施例提供的一种应用场景的示意图。如图1所示,第一电子设备100与第二电子设备200可进行无线通信。
示例性地,本申请实施例中第一电子设备100可以为移动设备、家用电器或者传感器设备等。例如,第一电子设备100可以为手机、平板电脑、个人计算机(personal computer,PC)、个人数字助理(personal digital assistant,PDA)、上网本、可穿戴设备(例如智能手表、智能手环)、增强现实技术(augmented reality,AR)设备、虚拟现实(virtual reality,VR)设备、车载设备、智慧屏、智能音箱、智能摄像头等移动设备。又例如,第一电子设备100可以是智能冰箱、智能电视、智能灯、智能插座、智能空气净化器、加湿器、智能油烟机、智能门锁、智能插线板、智能电磁炉、智能风扇、智能消毒盒、智能香薰机等智能家电。又例如,第一电子设备100还可以是烟雾传感器、燃气传感器、人体感应器、温度传感器、湿度传感器、门窗感应器、PM2.5空气传感器、门窗开关传感器、紧急按钮、报警器等传感器设备。第二电子设备200也可以是移动设备、家电电器或传感器设备中的任意一种。本申请实施例对第一电子设备100和第二电子设备200的具体形式均不做限定。
下面对第一电子设备100的结构进行说明。需要说明的是,第二电子设备200也可以参考第一电子设备100的结构,但第二电子设备200可以包括比第一电子设备100更多或更少的部件,或者组合某些部件,或者拆分某些部件,或者不同的部件布置。第二电子设备200可以与第一电子设备100为相同形式的电子设备,也可以为不同形式的电子设备,本申请实施例对此不做限定。
请参考图2,图2为本申请实施例提供的第一电子设备100的结构示意图。第一电子设备100可以包括一个或多个处理器110、一个或多个存储器120、以及一个或多个通信接口130、无线通信模块140以及一个或多个天线等。处理器110、存储器120、通信接口130、无线通信模块140通过总线相连接。
其中,处理器110可以为通用中央处理器(Central Processing Unit,CPU)、微处理器、特定应用集成电路(Application-Specific Integrated Circuit,ASIC),或者用于控制本申请方案程序执行的集成电路等。在一个示例中,处理器110可以包括多个CPU,并且处理器110可以是一个单核(single-CPU)处理器或多核(multi-CPU)处理器。单核处理器或多核处理器中的处理器可以指一个或多个设备、电路或用于处理数据(例 如计算机程序指令)的处理核。
存储器120,可以用于存储计算机可执行程序代码,所述可执行程序代码包括指令。内部存储器可以包括存储程序区和存储数据区。其中,存储程序区可存储操作系统以及本申请实施例需要使用的程序或指令等。
通信接口130,可用于与其他设备或通信网络通信,如以太网,无线局域网(wireless local area networks,WLAN)等。一些示例中,第一电子设备100也可以不包括通信接口130,本申请实施例对此不做限定。
无线通信模块140可以提供应用在第一电子设备100上的包括WLAN(如Wi-Fi)网络),蓝牙,NFC,红外技术等无线通信的解决方案。无线通信模块140可以是集成至少一个通信处理模块的一个或多个器件。无线通信模块140经由天线接收电磁波,将电磁波信号调频以及滤波处理,将处理后的信号发送到处理器110。无线通信模块140还可以从处理器110接收待发送的信号,对其进行调频,放大,经天线转为电磁波辐射出去。
在一些实施例中,如图2所示,第一电子设备100包括至少两个天线,例如天线1(第一天线,也称为强天线)和天线2(第二天线,也称为弱天线)。无线通信模块140可以在天线1和天线2之间进行切换。施加在天线1或天线2上的发射功率相同。其中,天线1的发射距离为第一距离。天线2的发射距离为第二距离。第二距离小于第一距离。例如,当无线通信模块140切换到天线1发送无线信号时,位于第一电子设备100的第一距离(例如,第一距离为6m、8m、10m)内的电子设备可接收到该无线信号。当无线通信模块140切换到天线2发送无线信号时,位于第一电子设备100的第二距离(例如,第二距离为30cm)范围内的电子设备可接收到该无线信号。第二距离小于等于预设的安全距离。预设的安全距离小于第一距离。第一距离、第二距离、预设的安全距离都可由用户根据需要自行调整设置。在一种实施方式中,第二距离可以为预设的安全距离。换言之,当第一电子设备100需要发送超短距的无线信号时,可以控制无线通信模块140连接到天线2,以发送超短距的无线信号。当第一电子设备100不需要发送超短距的无线信号时,可以控制无线通信模块140连接到天线1,以发送正常的无线信号。
在另一些实施例中,如图3所示,第一电子设备100可以包括可变电阻电路模块150和一个天线。可变电阻电路模块150可以在无线通信模块140的控制下改变电阻值的大小,从而改变同一天线的发射距离。也就是说,当可变电阻电路模块150的电阻值调整为电阻值1时,该天线的发射功率为第一发射功率(较高的发射功率),该天线的发射距离为第一距离。此时,位于第一电子设备100的第一距离(例如,第一距离为6m、8m、10m)内的电子设备可接收到该无线信号。当可变电阻电路模块150的电阻值调整为电阻值2时,该天线的发射功率为第二发射功率(较低的发射功率),该天线的发射距离为第二距离。第二发射功率小于第一发射功率。第二距离小于等于预设的安全距离。预设的安全距离小于第一距离。第一距离、第二距离、预设的安全距离都可由用户根据需要自行调整设置。在一种实施方式中,第二距离可以为预设的安全距离。换言之,当第一电子设备100需要发送超短距的无线信号时,可以控制可变电阻电路模块150的电阻值调整为电阻值2,以发送超短距的无线信号。当第一电 子设备100不需要发送超短距的无线信号时,可以控制可变电阻电路模块150的电阻值调整为电阻值1,以发送正常的无线信号。换句话说,在所述另一些实施例中,当可变电阻电路模块150的电阻值调整为电阻值1时,第一电子设备100连接第一天线。当可变电阻电路模块150的电阻值调整为电阻值2时,第一电子设备100连接第二天线;其中,第一天线和第二天线相同,但第一天线的发射距离大于第二天线的发射距离;第二天线的发射距离小于等于预设的安全距离,第一天线的发射距离大于预设的安全距离。第一天线的发射距离和第二天线的发射距离分别为上述的第一距离和第二距离。
示例性的,上述无线通信模块140采用的无线通信方式具体可以采用如BLE、Wi-Fi Aware等方式。其中,该无线通信方式是基于计算机网络MAC(Medium Access Control,媒体访问控制)层,又称为数据链路层协议扩展进行的交互,无需涉及到MAC层的上层网络通信,在数据链路层便可完整的实现数据交互。其中,BLE是由蓝牙特别兴趣小组于2016年推出的一种超低功耗的用于设备B的近距离无线通信方案,可通过MAC层实现通信。Wi-Fi Aware(Wi-Fi Neighborhood Aware Network,Wi-Fi邻居发现网络,又称为Wi-Fi Neighborhood Aware Network,简称NAN)是一种新型的低功耗点对点互连互通的Wi-Fi Mesh通信技术,该技术能够绕开网络基础设施(如接入点(Access Point,AP)或蜂窝网),实现一对一、一对多或多对多的设备间的连接通信,同样可通过MAC层实现通信。可以理解地,涉及的计算机网络的层数越高,其安全性就越难保证。本实施例采用的基于无线的MAC层通信,能够让数据基于数据链路层协议扩展进行交互,可显著地提高数据传输的安全性。
以下实施例中所涉及的技术方案均可以在具有上述结构第一电子设备100和第二电子设备200中实现。第一电子设备和第二电子设备均包含第一天线和第二天线。下面结合附图对本申请实施例提供的技术方案进行详细说明。
图4为本申请实施例提供的一种数据传输方法的流程示意图。如图4所示,该方法包括:
S401、第一电子设备接收到一个输入。
S401'、第二电子设备接收到一个输入。
其中,第一电子设备接收到一个输入,用于指示第一电子设备发送特定数据。该输入可以为用户输入,也可以为其他设备发送的指令。其中,用户输入包括用户操作特定按键、输入语音命令、特定的触摸操作、特定的隔空手势等。

在一些实施例中,第一电子设备可以通过Wi-Fi或蓝牙等无线方式广播请求。下面以第一电子设备采用Wi-Fi Aware技术发送传输特定数据的服务标识为例进行说明。
首先,对NAN机制进行简单说明。NAN机制是Wi-Fi联盟制定的一个标准。这个标准是在没有中心节点的情况下,所有参与NAN机制的设备(即NAN设备,例如第一电子设备、第二电子设备)同步起来。在NAN机制约定的发现时间窗(discovery window,DW)中进行NAN机制的维持工作和服务发现工作。其中,服务发现可通过发送服务发现帧(service discovery frame,SDF)消息实现。该服务器发现帧消息包括查询消息或广播消息。NAN设备基于服务发现消息中获得的信息,可以建立相应的连接,然后基于NAN智能管理。其中,SDF消息是一种专门定义用来做服务发现的动作帧。根据功能的不同,SDF消息帧大致可以分为三种,SDF发布(publish)消息、SDF订阅(subscribe)消息和SDF回复(follow-up)消息。其中,SDF publish消息,用于发布NAN设备所能提供的服务,或者用于回复其他NAN设备发送的NAN subscribe消息。NAN subscribe消息,用于查找需要使用的服务。SDF follow-up消息,用于回复收到的SDF publish消息,或者用于协商更多的信息。一般,在SDF消息中包含一个指示,用于指示该消息属于那种SDF消息。
作为一个示例,第一电子设备可以在SDF publish消息中携带传输特定数据的服务 标识、第一电子设备的标识等信息。作为另一个示例,第一电子设备可以通过BLE beacon中携带传输特定数据的服务标识、第一电子设备的标识等信息。

作为一个示例,第二电子设备可以在SDF Follow-up消息中携带第一随机数。作为另一个示例,第二电子设备可以通过BLE beacon中携带第一随机数。
前文已说明,由于第二电子设备通过第二天线发送的第二消息,只有距离第二电子设备在极短的距离范围(例如30cm)内的电子设备才能接收到。因此,可以保证接收到第二消息的电子设备为第二电子设备的可信设备。
在一些实施例中,第二电子设备在发送第二消息之前,可以采用语音提示或灯闪烁等方式,提示用户将第一电子设备靠近第二电子设备。当然,第二电子设备也可以在其他时机提示用户,例如在接收到第一电子设备发送的第一消息之后。还可以由第一电子设备提示用户,靠近第二电子设备。本申请实施例对提示方式、提示时机等均不做限定。

S411、第一电子设备切换至第一电子设备的第一天线。
具体的,例如,第一电子设备具备图2所示的结构时,第一电子设备可以控制无线通信模块140连接第一天线。示例性的,第一电子设备具备图3所示的结构时,第一电子设备控制可变电阻电路模块150的电阻值为第一电阻值(较小的电阻值),使得第一电子设备的天线发射功率为第一发射功率。
在其他一些实施例中,第一电子设备也可以在其他时间切换至第一天线。例如,在执行完S409之后,即发送完第三消息后,第一电子设备切换回第一天线。又例如,在执行S413,即向第一电子设备通过第一天线,向第二电子设备发送第四消息之前,第一电子设备切换回第一天线。本申请实施例对此不做限定。
S412、第一电子设备使用会话密钥加密第一电子设备的特定数据,得到加密后的数据,根据加密后的数据生成第四消息。

S411'、第二电子设备切换至第二电子设备的第一天线。
具体的,例如,第二电子设备具备图2所示的结构时,第二电子设备可以控制无线通信模块140连接第一天线。再示例性的,第二电子设备具备图3所示的结构时,第二电子设备控制可变电阻电路模块150的电阻值为第一电阻值(较小的电阻值),使得第二电子设备的天线发射功率为第一发射功率。
在其他一些实施例中,第二电子设备也可以在其他时间切换至第一天线,例如,在执行完S405之后,即发送完第二消息后,第二电子设备切换回第一天线。又例如,在执行S416,即第二电子设备通过第一天线,向第一电子设备发送特定数据传输成功的消息之前,第二电子设备切换回第一天线。本申请实施例对此不做限定。
S412'、第二电子设备根据第一随机数、第二随机数生成会话密钥。
需要说明的是,这里第二电子设备生成会话密钥采用的算法,与第一电子设备生成会话密钥采用的算法相同,从而使得两个电子设备生成的会话密钥是相同的。进而,可以使用生成的会话密钥解密对端电子设备发送的数据。
S413、第一电子设备通过第一天线,发送第四消息。
示例性的,第一电子设备可以通过无线连接的方式(例如Wi-Fi或者蓝牙)广播发送加密的特定数据。例如,第二电子设备可以在SDF Follow-up消息中或者BLE beacon中携带加密的特定数据。或者,第一电子设备与第二电子设备建立点到点的无线连接(例如Wi-Fi或者蓝牙),通过无线连接向第二电子设备发送加密的特定数据。

本实施例中不限定S417和S417'的执行顺序。另外,本申请实施例可以执行S417和S417'中任一个步骤,或者两个步骤均执行,或者两个步骤均不执行。
由此可见,本申请实施例提供的数据传输方法中,第一电子设备和第二电子设备通过切换至第二天线发送超短距无线信号来协商会话密钥,完成对双方的认证。由于第一电子设备和第二电子设备只有位于第二天线的发射距离(第二天线的发射距离小于等于预设的安全距离)内,才能接收到对端电子设备发送的超短距无线信号。因此,通过发送超短距无线信号来协商会话密钥,可以提升通信的安全性,也有利于简化密钥协商的流程,从而实现快速传输特定数据。并且,可以注意到,密钥协商的过程中不需要用户手动输入验证码等信息,也降低了用户操作的复杂度。

在第一电子设备执行S510-S512的过程中,第二电子设备执行S510'-S512'。具体如下:

下面介绍几种本申请实施例提供的技术方案的应用场景的示意。
场景一、用户新购大量设备类型相同或相似的设备。这些设备的设置信息相同或类似。于是,用户可以先通过例如手机等对其中一个电子设备进行设置。已设置好的电子设备即为第一电子设备。然后,将已设置好的电子设备的配置信息直接克隆到其他电子设备(即第二电子)上,以完成其他电子设备的设置。
例如,新购入多个智能照明设备(智能台灯、吸顶灯、智能灯带、香薰灯等)。用户可以先通过手机与其中的照明设备A建立无线连接,通过“智慧生活”或者其他应用,对照明设备进行配网、设置亮度色温等灯光参数,是否延迟关闭、延迟关闭的时长、是否自动进行固件升级、用电量门限设置等。即,照明设备A存储有配置信息。而后,用户可以将照明设备A的配置信息克隆到其他的照明设备上(例如照明设备B、照明设备C等)。
在一种实施方式中,照明设备A和照明设备B在分别接收到一个输入后,照明设备A与照明设备B相互靠近至30cm的范围内时,照明设备A的配置数据传输至照明设备B。这样,用户仅需对照明设备A和照明设备B触发一个输入后,将两者相互靠近至预设的安全距离内,两者即可实现特定数据的传输。用户的操作非常简便,尤其适于老人、孩子等理解能力、操作能力较弱的人,便于掌握。
在一种实施方式中,特定数据可由电子设备的控制设备或绑定设备预先设置好。比如,主人的手机可预先设置IoT灯的特定数据为配置数据。
需要注意的是,本申请实施例利用了超短距无线通信的安全距离传输密钥,在第一天线工作时,传输密钥加密后的数据,并在另一电子设备处实现解密,从而在物理上保证了照明设备A与照明设备B之间传输的安全性,消除了中间设备的攻击以及数据泄露风险。
而后,可以采用相同的方法完成将照明设备A的配置信息克隆到照明设备C等其 他设备上。或者,采用相同的方法完成照明设备B的配置信息克隆到照明设备C等其他设备上。
由上可见,对于需要给多个电子设备设置相同的配置信息时,可以先对设置其中一个电子设备。而后,将设置好的电子设备中的配置信息直接克隆到其他电子设备上。简化了用户分别设置多个电子设备的流程,提高了设置多个电子设备的效率。
又例如,在智能家居生活中,通常需要设置大量的传感器。例如,烟雾传感器、燃气传感器、水浸探测器、异响传感器等。这些传感器虽然为不同类型的传感器,但配置信息大体上相同或类似。配置信息例如包括接入网络的网络信息、告警触发动作、静默时间、定时器设置、固件升级设置等。因此,也可以采用本申请实施例的方法,先对其中一个传感器进行设置,再使用设置好的传感器将配置信息克隆到其他传感器,以避免对类似的传感器重复进行设置,简化用户操作,提高设置效率。
此外,由于本申请实施例提供的方法极少涉及到用户界面操作,针对智能家居中大量的没有显示屏的设备来说,本申请实施例提供的方法更加友好,便于实现。
场景二、用户使用新的电子设备更换旧的电子设备。新的电子设备通常与旧的电子设备为类型相同的设备,且型号接近。那么,可以直接将旧的电子设备上的配置信息和/或用户数据克隆到新的电子设备上。从而避免将旧的电子设备上的配置信息和/或用户数据导出到中间设备,再由中间设备导回到新的电子设备,提升了数据的安全性,又简化了用户操作。
场景三、家庭中某个不能上网或者配网失败的IoT设备发生运行故障。一般,IoT设备出现故障时,会通过网络将运行日志发送到手机或电脑上。或者,IoT设备通过例如串口等通信接口打印运行日志到手机或电脑上,以便用户进行故障分析,问题定位。在本方案中,可以将IoT设备的运行日志通过超短距的方式发送其他电子设备上,通过其他电子设备查看该电子设备的运行日志,便于对该电子设备进行故障分析,以便维护该电子设备。由此解决了不能上网或者配网失败或者不具有外接通信接口的IoT设备的维护问题。
例如,如图8中的(1)所示,用户可以打开手机中“智慧生活”APP,进入家居设备列表界面801。可见,手机绑定有空调、智能台灯以及智能音箱三个设备。其中,智能台灯处于未连网状态。进一步的,响应于用户操作控件802,手机向智能台灯发送请收集智能台灯的运行日志的消息,即,执行S702,以及执行之后的步骤。在手机收集智能台灯的过程中,手机还显示如图8中的(2)所示的提示界面803。提示界面803中的提示信息804,用于提示用户正在收集智能台灯的运行日志。在手机成功接收到智能台灯的运行日志后,手机可以显示如图8中的(3)所示的提示界面805,其中提示信息806用于提示用户已成功收集到智能台灯的运行日志。可选的,提示信息806还包括查看控件807。响应于用户操作控件807,手机显示智能台灯的运行日志,便于用户对智能台灯的运行情况进行故障分析等。需要注意的是,在另一些实施例中,手机与智能台灯也可以没有预先进行绑定,手机也可以请求收集该智能台灯的运行日志,本申请对此不做限定。
