Description

一种婴儿监护器的通信方法及婴儿监护器 技术领域
本申请涉及无线传输技术领域,特别涉及一种婴儿监护器的通信方法及婴儿监护器。
背景技术
市场上现有的婴儿监护器(baby monitor)主要使用以下方式来实现无线通信:
1、婴儿监护单元(Baby monitor unit,下称BU)与家长监护单元(Parents unit,下称PU)仅使用专用的RF模块进行点对点的通信。
2、BU与PU使用专用的RF模块进行本地的点对点通信,同时,BU使用2.4G WIFI模块与局域网或Internet(因特网)上的设备进行通信。
现有技术的缺点如下:
对于第1种方式,如果仅使用专用的RF模块进行BU与PU间的点对点通信,首先无法使BU直接连接上因特网,更无法直接与因特网上的其他设备进行通信。其次,一些常用的RF模块(如使用FHSS即跳频技术的模块),往往会存在最大通信带宽受限的问题。另外,BU与PU间的点对点通信协议需要定制化开发,无法使用一些常用的开源网络通信协议,增大了开发的工作量。
对于第2种方式,如果设备使用RF模块进行BU与PU间的点对点通信,同时再使用另一块2.4G WIFI模块进行局域网或Internet通信。这需要使用两种无线通信模块,无疑会加大开发的复杂度,两种模块间的干扰问题也会在一定程度上影响产品的传输性能。

本申请实施例提供一种儿童监视方法,其包括:
S101、在婴儿监护单元中虚拟出两个WIFI接口:第一WIFI接口和第二WIFI接口;
S102、对所述第一WIFI接口进行目标路由器信息的配置,并向目标路由器申请第一IP地址,以加入目标路由器所在网络;
S103、对所述第二WIFI接口进行AP信息的配置,并在婴儿监护单元接收到本地的家长监护单元的连接申请后对家长监护单元进行身份认证,认证通过后与家长监护单元进行本地的点对点连接;
S104、所述婴儿监护单元通过所述第一WIFI接口发送主码流至指定设备,以及通过所述第二WIFI接口发送次码流至家长监护单元;或者,所述婴儿监护单元通过所述第一WIFI接口发送次码流至指定设备,以及通过所述第二WIFI接口发送主码流至家长监护单元。
本申请实施例为了实现同时兼容婴儿监护单元(BU)与家长监护单元(PU)的本地远距离点对点通信,以及BU与Internet上的设备(如手机)的远程通信,通过分时复用的方式使BU内的WIFI接口,可以保持STA(Station,无线工作站或无线终端节点)与AP(AccessPoint,即无线接入点,可供无线终端设备接入)同时工作,即BU内的WIFI工作模式为STA+AP模式。本申请实施例充分利用WIFI底层的分时复用机制,从不同WIFI接口分时传输主码流及子码流数据,从而避免信道相互干扰,提高传输质量。
与传统的儿童监视器方案相比,本申请实施例只需单个通用的WIFI模块,简化了硬件、软件开发工作,节约了产品成本。并且由于只采用单个通用的WIFI模块,避免了使用不同RF模块引入的干扰问题,提升了产品性能。
具体地,如图1所示,在所述步骤S101中,先在BU中虚拟出两个WIFI接口:第一WIFI接口和第二WIFI接口。例如,通过WIFI驱动代码配置及linux内核网络相关接口,如图3所示,将WIFI模块在linux用户空间虚拟出两个WIFI接口,分别为第一WIFI接口和第二WIFI接口。其中,第一WIFI接口作为STA接口,第二WIFI接口作为AP接口。
在所述步骤S102中,可以使用Wpa_supplicant工具对第一WIFI接口进行网络的连接操作及管理工作,并进行目标路由器信息的配置,然后向目标路由器申请第一IP地址(网段1),加入目标路由器所在网络。
进一步,所述步骤S102包括:
通过第一配置文件对所述第一WIFI接口进行目标路由器信息的配置,以及通过dhcp客户端向目标路由器申请第一IP地址,以加入目标路由器所在网络。
本实施例中,可通过第一配置文件进行目标路由器信息的配置,并且可通过dhcp客户端(udhcpc)向目标路由器申请第一IP地址(网段1),目标路由器即对BU进行认证,认证通过后可返回连接信息(包含第一IP地址)至BU,BU即可加入目标路由所在网络器。
在所述步骤S103中,可以使用Hostapd软件工具可以对第二WIFI接口进行AP服务启动及管理,即对所述第二WIFI接口进行AP信息的配置。本地的PU可向BU发送连接申请,BU接收到本地的PU的连接申请后,可对PU进行身份认证,认证通过后与本地的PU进行连接。
进一步,所述步骤S103包括:
通过第二配置文件对所述第二WIFI接口进行AP信息的配置,并运行dhcp服务;
当所述婴儿监护单元接收到本地的家长监护单元的连接申请时,所述婴儿监护单元对所述家长监护单元进行认证,并在认证通过后向家长监护单元分配第二IP地址。
本实施例中,可通过第二配置文件进行AP信息的配置,并运行dhcp服务。BU可通过dhcp服务端(udhcpd)向PU通过提供服务,PU可通过dhcp服务向BU发送连接申请,即申请第二IP地址(网段2),BU对连接申请进行认证,认证通过后向PU分配第二IP地址,这样可以实现BU与PU之间的点对点连接,当然一个BU可以与多个PU进行点对点的连接。
在所述步骤S104中,在BU加入目标路由器所在网络之后,BU通过目标路由器与Internet上的设备进行通信(包括且不仅局限于音视频流通信),例如BU可通过第一WIFI接口将其主码流发送给网络上的设备,例如服务器或移动终端等等, 实现预览或者录制保存功能。在BU与PU之间完成点对点的连接之后,BU即可与本地的PU进行通信(包括且不仅局限于音视频流通信),为了实现远距离的通信,可以进行次码流的传输,这样可以实现本地远距离的PU对于次码流的预览及录制。
当然,本申请实施例中,所述婴儿监护单元也可以通过所述第一WIFI接口发送次码流至指定设备,以及通过所述第二WIFI接口发送主码流至家长监护单元。即并不限定只能通过第一WIFI接口将主码流发送给网络上的设备,也不限定只能通过第二WIFI接口将次码流发送至家长监护单元,二者也可以调换发送的码流。
在一实施例中,所述次码流的分辨率或码率小于所述主码流的分辨率或码率。次码流相对于主码流来说,对于吞吐量要求低,更适合于本地远距离的传输。
在一实施例中,所述的儿童监视方法还包括:
通过所述婴儿监护单元和所述家长监护单元的WIFI驱动提供的WIFI控制接口设置所述婴儿监护单元和所述家长监护单元间的点对点连接的数据传输速率。
在BU及PU的linux内核空间均提供有WIFI驱动,通过WIFI驱动提供的WIFI控制接口可以设定数据传输的速率,这样BU及PU可根据实际情况(实际码流所需带宽)来选择合适固定的速率用于传输数据。为了提升本地远距离通信的抗干扰能力,BU与PU间双向通信的数据传输速率,可以优先选择802.11b中抗干扰性能较好的低速速率。
本申请实施例还提供一种婴儿监护器,其包括:婴儿监护单元和至少一家长监护单元;
所述婴儿监护单元中虚拟有两个WIFI接口:第一WIFI接口和第二WIFI接口;
所述婴儿监护单元用于接收所述第一WIFI接口进行目标路由器信息的配置,并向目标路由器申请第一IP地址,以加入目标路由器所在网络;
所述婴儿监护单元用于接收对所述第二WIFI接口进行AP信息的配置,并在婴儿监护单元接收到本地的家长监护单元的连接申请后对家长监护单元进行身份认证,认证通过后与家长监护单元进行点对点连接;
所述婴儿监护单元用于通过所述第一WIFI接口发送主码流至指定设备,以及通 过所述第二WIFI接口发送次码流至家长监护单元;或者,所述婴儿监护单元用于通过所述第一WIFI接口发送次码流至指定设备,以及通过所述第二WIFI接口发送主码流至家长监护单元。
在一实施例中,如图2和图3所示,所述婴儿监护单元和所述家长监护单元中均设置有FEM模块,用于所述婴儿监护单元和所述家长监护单元间本地通信的信号接收和发送。在一实施例中,为了更好的实现BU与PU本地远距离通信,还可以在BU与PU的WIFI模块前端均加入FEM模块(即射频前端模块),所述FEM模块是一种低噪声的接收和发送信号放大器,可以降低噪声。随着集成电路的普及,越来越多的模块从分立器件转到了集成电路上。然而,有一些器件由于各种各样的原因,目前还无法集成到传统集成电路上。这些无法集成到集成电路上的射频器件通常称为射频前端模块。FEM模块离基带较远而离天线较近,所以通常被称为射频前端模块。典型的FEM模块包含如下器件:1.天线相关的器件:天线调谐器(Antenna Tuner)与天线开关(Antenna Switch);2.多路器(diplexer)与收/发开关(T/R Switch);3.滤波器;4.功率放大器(PA)。5.低噪声放大器(LNA)。
在一实施例中,所述指定设备为服务器或移动终端。
在一实施例中,所述次码流的分辨率或码率小于所述主码流的分辨率或码率。
由于系统部分的实施例与方法部分的实施例相互对应,因此系统部分的实施例请参见方法部分的实施例的描述,这里暂不赘述。
说明书中各个实施例采用递进的方式描述,每个实施例重点说明的都是与其他实施例的不同之处,各个实施例之间相同相似部分互相参见即可。对于实施例公开的装置而言,由于其与实施例公开的方法相对应,所以描述的比较简单,相关之处参见方法部分说明即可。应当指出,对于本技术领域的普通技术人员来说,在不脱离本申请原理的前提下,还可以对本申请进行若干改进和修饰,这些改进和修饰也落入本申请权利要求的保护范围内。
还需要说明的是,在本说明书中,诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来,而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且,术语“包括”、“包 含”或者其任何其他变体意在涵盖非排他性的包含,从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素,而且还包括没有明确列出的其他要素,或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限制的状况下,由语句“包括一个......”限定的要素,并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。
