本发明的实施方式
为了使本申请的目的、技术方案及优点更加清楚明白,以下结合附图及实施例,对本申请进行进一步详细说明。应当理解,此处描述的具体实施例仅仅用以解释本申请,并不用于限定本申请。
本申请提供的天线匹配方法,可以应用于如图1所示的应用环境中。其中,移动终端102通过网络与服务器104通过网络进行通信;用于解决移动终端的通信质量差的问题。其中,移动终端102可以但 不限于是各种个人计算机、笔记本电脑、智能手机、平板电脑和便携式可穿戴设备,服务器104可以用独立的服务器或者是多个服务器组成的服务器集群来实现。
在一个实施例中,如图2所示,提供了一种天线匹配方法,以该方法应用于图1中的移动终端为例进行说明,移动终端包括多个天线,天线匹配方法,包括以下步骤:
S10:获取移动终端的状态信息,根据所述状态信息判断所述移动终端当前是否处于通信状态。
其中,移动终端的状态信息为用于指示移动终端当前状态的信息。通过获取的状态信息可确定移动终端当前的工作状态,即确定当前移动终端当前是否处于通信状态,还是处于视频播放状态,或者是处于待机状态。需要说明的是,在本实施例中,获取移动终端的状态信息的主要目的在于确定移动终端当前是否处于通信状态。
示例性的,可通过直接检测移动终端前台正在运行的应用程序的类型来获取移动终端的状态信息,以确定移动终端当前的工作状态。其中,该应用程序可以为播放软件类,例如,爱奇艺视频播放器、腾讯视频播放器、西瓜影音视频播放器、优酷视频播放器等;也可以为通信软件类,例如:电话通话、微信、QQ等。当然,还可以包括其他类型的软件,例如高德地图、饿了吧、美团外卖等常用软件来获取移动终端的状态信息。若检测到移动终端前台正在运行的应用程序为爱奇艺视频播放器,在可以确定移动终端当前处于视频播放状态。若检测到移动终端前台正在运行的应用程序为电话通话,则可以确定移动终端当前处于通信状态。
示例性的,也可通过监听用户在移动终端的页面操作行为来获取移动终端的状态信息。可以通过在移动终端引入监听脚本插件,从而实时监听用户在移动终端的页面操作行为。监听脚本插件指插入了js监听文件脚本的插件,js监听文件属于一段js监听代码,指在全局的dom文档的<body>标签上绑定监听事件的函数。此外,对于项目公共的js文件,可直接在移动终端的页面上导入js监听文件即可实现对 用户在移动终端的操作行为的监听。在该步骤中,可以使用脚本作为js监听文件的载体,由于脚本具有可由应用程序临时调用并执行的功能特征,更方便监听脚本插件的使用。监听脚本插件一旦监听到用户在移动终端的操作行为的,会对用户的页面操作行为进行响应,以获取到移动终端的状态信息,再根据状态信息判断所述移动终端当前是否处于通信状态。若监听到用户在移动终端的页面操作行为为拨打号码或者接听电话,则可以确定移动终端当前处于通信状态。
S20:若移动终端处于通信状态,则确定移动终端处于通信状态下的工作模式。
其中,通信状态又分为免提通话模式、耳机通话和手持通话模式等。因此,在本实施例中,在判断得到移动终端处于通信状态之后,然后再进一步判断移动终端当前处于的通信状态是为免提通话模式,还是为耳机通话模式,或者是为手持通话模式。
S30:若所述移动终端处于通信状态的工作模式为第一工作模式,则采用传感器检测模块获取检测信息。
其中,第一工作模式为指示当前移动终端处于通信状态中的手持通话模式。手持通话模式包括接听模式和拨打模式。需要说明的是,手持通话模式可以是电话通话程序中的手持通话模式,也可以是微信程序中的手持通话模式,还可以是QQ程序中的手持通话模式。
当确定移动终端处于通信状态中的手持通话模式之后,触发移动终端中的传感器检测模块获取检测信息。其中,传感器检测模块可以为动作传感器、加速度传感器或者陀螺仪传感器,或者是以上传感器的组合。通过传感器检测模块可用于检测用户对移动终端的操作是否为特定握持状态。在本实施例中,通过传感器检测模块可检测出用户是否将移动终端贴近用户的耳部,以及移动终端贴近用户的耳部时,用户对移动终端当前的握持手势。
示例性的,可以根据移动终端当前的倾斜角度,并根据倾斜角度的角度范围确定移动终端当前的握持手势,以获取到用户对移动终端的手势数据。也即本申请可以根据移动终端的倾斜角度确定握持状态。 可以将移动终端中的传感器检测模块(比如:陀螺仪传感器)检测到移动终端当前的倾斜角度作为手势数据,并根据该倾斜角度确定用户对所述移动终端的握持手势状态。
在实际应用过程中,用户握持移动终端时,会施加力至移动终端的边缘触摸区域,且不同的握持手势,触摸操作的位置分布也不同,因此,示例性的,还可以通过边缘触摸区域内当前触摸操作的触摸位置即可判断当前的握持手势,以获取用户对移动终端的手势数据。其中,边缘触摸区域既可以是电子设备的左、右侧边上设置的触摸区域,也可以是电子设备正面触摸屏上的左、右边缘区域。因此,还可以通过采用传感器检测模块(压力传感器)将移动终端的左、右两侧边上的触摸区域内检测到的触摸操作的压力信息作为检测信息,该检测信息用于表征触摸位置,即当前触摸操作所在的区域或位置,以实现通过压力传感器检测到的压力信号值。
S40:根据手势数据确定用户对所述移动终端的握持手势状态。
通过手势数据即可确定用户对移动终端的握持手势状态,即确定用户手持移动终端时是采用右手还是左手。在一实际应用过程中,由于人体是一种导体,因此用户对移动终端的握持手势状态不同,则对移动终端中的天线谐振的影响也不同。例如,用户左手握持移动终端时和右手握持移动终端时对移动终端的天线谐振的影响就不同,因此,本实施例在采用传感器检测模块获取到用户对移动终端的手势数据之后,根据该手势数据确定用户对移动终端当前的握持手势是采用右手还是采用左手。
S50:基于用户对移动终端的握持手势状态从所述多个天线中匹配对应的目标天线。
在确定了用户对移动终端的握持手势状态之后,即确定了用户对移动终端当前的握持手势是采用右手还是采用左手之后,从移动终端的多个天线中匹配对应的目标天线。示例性的,已预先确定好了左手模式下所对应的天线和右手模式下所对应的天线,且预先将它们相关联;在确定了用户对移动终端当前的握持手势是采用右手还是采用左 手之后,可直接从移动终端的多个天线中匹配到对应的目标天线。
示例性的,由于只基于用户对移动终端的握持手势状态从多个天线中所匹配到的对应的目标天线可能不止一种情况,因此,为了提高匹配到的目标天线所接收的信号质量,在基于用户对移动终端的握持手势状态从多个天线中匹配对应的目标天线之后前,还可以根据当前的通信类型,从匹配到的对应的目标天线中将不符合该通信类型的天线过滤掉,然后从符合通信类型的天线中来筛选匹配出最终的目标天线,最后将移动终端当前所用的天线切换为目标天线。其中,通信类型可以包括蓝牙、WIFI、5G、4G、3G等通信。
在本实施例中,获取所述移动终端的状态信息,根据所述状态信息判断所述移动终端当前是否处于通信状态;若所述移动终端处于通信状态,则确定所述移动终端处于通信状态下的工作模式;若所述移动终端处于通信状态的工作模式为第一工作模式,则采用传感器检测模块获取用户对所述移动终端的手势数据;根据所述手势数据确定用户对所述移动终端的握持手势状态;基于用户对所述移动终端的握持手势状态从所述多个天线中匹配对应的目标天线;通过先确定移动终端当前的工作模式是否处于通信状态,然后再识别出移动终端处于通信状态下时用户对移动终端当前的握持手势状态,以匹配出最佳的目标天线,从而不但可实现天线的自由切换,还能进一步提高通信速率和质量。
在一实施例中,如图3所示,根据手势数据确定用户对移动终端的握持手势状态,包括如下步骤:
S401:将手势数据输入到预设的手势数据模板库中。
其中,手势数据模板库为预先创建的用于存储手势数据的数据库。在手势数据库中存储有若干不同的样本手势数据。由于手势数据中包含有用户对移动终端当前的握持手势,因此,在获取的手势数据之后,将该手势数据输入到预设的手势数据库中,以从手势数据库中筛选出与该手势数据匹配度最高的目标手势模板。
S402:从手势数据模板库中筛选出与手势数据匹配度最高的目标 手势模板,其中,目标手势模板包括手势动作信息。
将手势数据输入到手势数据模板库中,然后进行在线匹配,从手势数据模板库中筛选出与该手势数据匹配度最高的目标手势模板。其中,目标手势模板指与手势数据中的握持手势匹配度最高的模板。手势数据手势模板包括手势动作信息。手势动作信息指可用于评估用户对移动终端当前的握持手势动作的信息。
在本实施例中,可采用相似度算法,从手势数据模板库中筛选出与手势数据匹配度最高的目标手势模板。其中,相似度算法是用于计算两个物体之间相似度的算法。相似度算法可以为文本相似度算法、余弦相似度算法或编辑距离算法。由于相似度算法可计算两个向量之间的相似度。因此,需预先对手势数据进行特征提取,获取手势数据中的手势特征;然后将该手势特征的和每一手势模板中的手势动作特征分别转换成向量A=(A1,A2,……,An)和向量B(B1,B2,……,Bn);再采用相似度算法计算手势特征的和每一手势模板中的手势动作特征之间的相似度,最后将计算得到与该手势特征相似度最高的手势模板作为匹配度最高的目标手势模板。
S403:基于手势动作信息确定用户对移动终端的握持手势状态。
最后基于目标手势模板中的手势动作信息确定用户对移动终端的握持手势状态,即确定用户手持移动终端时是采用右手还是左手。
本实施例中,通过将手势数据输入到预设的手势数据模板库中,然后从手势数据模板库中筛选出与手势数据匹配度最高的目标手势模板,其中,目标手势模板包括手势动作信息,最后基于手势动作信息确定用户对所述移动终端的握持手势状态,从而实现快速、准确地确定用户对移动终端的握持手势状态,提高后续从多个天线中匹配对应的目标天线的效率。
在一实施例中,在根据状态信息判断移动终端当前的工作模式之后,天线切换还包括如下步骤:
若所述移动终端处于通信状态的工作模式为第二工作模式,则根据所述移动终端的工作模式,从所述多个天线中匹配出对应的默认天 线。
其中,第二工作模式为指示当前移动终端处于通信状态的非手持通话的模式。例如:将通信状态中的免提通话模式或者耳机通话模式均归为第二工作模式,即将移动终端当前处于通信状态的非手持通话模式确定为移动终端的第二工作模式。
若移动终端处于通信状态的工作模式为第二工作模式,则根据所述移动终端的通信类型,从所述多个天线中匹配出对应的默认天线。其中,默认天线为预先设定与用户是否手持通话无关、与移动终端的通信类型有关的天线。在本实施例中,为了提高移动终端处于通信状态的第二工作模式下的信号质量,可根据移动终端当前的通信类型,筛选出符合该通信类型的默认天线。其中,通信类型可以包括蓝牙、WIFI、4G、3G、2G等通信。例如:若移动终端当前的通信类型为4G,则根据通信类型信息4G匹配到对应的默认天线。示例性的,由于移动终端处于不同的通信类型时所对应默认连接的天线不同,因此,在确定了通信类型之后,可直接匹配到对应该通信类型的默认天线,从而可提高移动终端处于通信状态的第二工作模式下的信号质量。
在一实施例中,如图4所示,在根据手势信息确定用户对移动终端的握持手势状态之前,所述天线切换还包括如下步骤:
S11:获取原始手势数据,对原始手势数据进行去噪处理,生成标准手势数据,标准手势数据包括三轴角速度数据。
其中,原始手势数据为预先包含有用户手持移动终端进行通信的手势状态的数据。示例性的,可以预先采用带有陀螺仪传感器的移动终端、测试板或者其它电子设备对用户在使用移动终端时的手持姿势进行采集;也可以直接从互联网或第三方机构/平台所公开的用户手持移动终端的姿势数据库中获取原始手势数据。例如:在用户进行动作手势的过程中,采集这段时间内的移动终端内置陀螺仪的三轴角速度数据,采样频率为50Hz。假设a=(x,y,z)表示移动终端三轴角速度,则t时刻的三轴角速度为at=(xt,yt,zt),采集的一段时间内的数据序列为A=(A1,A2,……,An),n为采集的数据个数。
示例性的,由于获取的原始手势数据中可能存在较大的噪音,比如存在用户不是在通信状态下的手势数据,或者存在用户在通信状态下的手势数据是不符合要求(比如:用户是在耳机通信模式下的手势数据),因此,为了提高最后生成的手势数据模板库中的样本手势数据的准确性,在获取到原始手势数据之后,需先对原始手势数据进行去噪处理,即去除用户均处于非通信状态下的手持终端的手势数据,生成标准手势数据。其中,标准手势数据为用户均处于通信状态下的手持终端的手势数据。
S12:基于三轴角速度数据从标准手势数据中截取有效手势数据。
要识别动作手势,需要首先准确识别手势的开始与结束,以便截取有效的手势数据。在进行手势动作时,移动终端的三轴角速度数据变化明显,而没有进行手势动作时数据较平稳。由于方差能够反应一段时间内的数据变化,因此我们根据角速度数据的均方差来判断手势数据的开始和结束,并进行手势数据的截取。均方差var的计算公式如下:
Figure PCTCN2022110046-appb-000001
其中N为计算均方差的数据个数,
Figure PCTCN2022110046-appb-000002
分别为x,y,z轴角速度的均值。当var大于等于动作手势开始阈值时,即var≥varbegin,则认为手势动作开始;当var小于等于动作手势结束阈值时,即var≤varend,则认为手势动作结束。
进一步地,由于在手势数据截取过程中,用户误操作或者手部晃动产生的噪声会被当作手势数据,因此为了去除这些干扰噪声,本申请规定均方差var需要连续Nbegin次(即手势开始持续阈值)大于varbegin才认为有效手势数据开始,这样由于晃动产生的噪声数据就不会被当成有效数据,从而可有效提高截取的有效手势数据准确性。
S13:对所述有效手势数据进行预处理,生成样本手势数据。
本实施例中对有效手势数据进行预处理主要包括先对有效手势数据进行平滑处理,然后再对平滑处理后的有效手势数据进行归一化处理,再对归一化处理后的有效手势数据进行三次样条插值处理,最后对所述三次样条插值处理后的有效手势数据进行假波峰波谷处理,生成样本手势数据。
S14:基于所述样本手势数据形成手势数据模板库。
手势数据模板库中存放各动作手势的最终数据模板。针对同一动作手势,采集多条手势数据序列,并进行有效手势数据截取和预处理;从同一手势的多条数据序列中,任意选取一条作为临时手势模板;将同一手势的其余数据序列依次与临时模板进行DTW匹配,计算相似度总和。计算方法为:假设临时手势模板为R=(r1,r2,...,rn),手势数据序列为T=(t1,t2,...,tm),R中数据ri和T中数据tj的相似度表示为ri和tj之间的欧式距离dij,R中前i个数据和T中前j个数据之间的相似度Dij计算为:
Figure PCTCN2022110046-appb-000003
Dij即为临时手势模板为R与手势数据序列T之间的相似度。计算临时手势模板R与所有同一手势的数据序列的相似度并求和,就得到相似度总和。对同一手势中的每一条数据序列重复上述步骤,得到该数据序列与其它数据序列的相似度总和,选取相似度总和最大的数据序列,即Dnm最小的数据序列,作为该手势的最终模板;最后对所有样本手势数据本重复上述步骤,以实现建立手势数据模板库。
在本实施例中,获取原始手势数据,对所述原始手势数据进行去操处理,生成标准手势数据,所述标准手势数据包括三轴角速度数据;基于所述三轴角速度数据从所述标准手势数据中截取有效手势数据;对所述有效手势数据进行预处理,生成样本手势数据,基于样本手势数据形成手势数据模板库;通过预先采集大量原始手势数据,然后对 原始手势数据进行数据处理以形成手势数据模板库,从而便于后续直接采用手势数据模板库匹配出所需的目标手势模板,可提高数据处理的效率,以进一步提高通信速率。
在一实施例中,如图5所示,对所述有效手势数据进行预处理,生成样本手势数据,包括如下步骤:
S131:对所述有效手势数据进行平滑处理。
由于手的细微晃动和传感器自身非精确性带来的影响,使得采集到的有效手势数据具有一定噪声,影响识别精度。本实施例通过采用简单滑动平均算法对手势截取后的有效手势数据具中的角速度数据进行平滑以去除噪声。假设手势截取后的数据为A=(a1,a2,…,am),滑动窗口大小为M,则平滑后第i个数据为:
Figure PCTCN2022110046-appb-000004
S132:对平滑处理后的有效手势数据进行归一化处理。
进一步地,由于用户做手势时的差异性,导致不同用户做相同手势时幅度不同,对识别的精度造成较大影响,因此本申请在对角速度数据平滑后,进行数据归一化处理。假设,X=(x1,x2,…,xm),Y=(y1,y2,…,ym)和Z=(z1,z2,…,zm)分别代表(x,y,z)轴的角速度数据,则归一化如下:
Figure PCTCN2022110046-appb-000005
归一化之后的数据为:
Figure PCTCN2022110046-appb-000006
Figure PCTCN2022110046-appb-000007
S133:对归一化处理后的有效手势数据进行三次样条插值处理。
其次,由于采用的动作手势识别算法要求动作手势的数据波形在分段区域内具有单调性,因此需要对动作手势数据进行三次样条插值分段拟合处理。假设角速度数据序列为A=(a1,a2,…,am),在[a1,am]上等距划分Δ:a1=x0<x1<…<xk=am,拟合公式为:
Figure PCTCN2022110046-appb-000008
Figure PCTCN2022110046-appb-000009
S134:对所述三次样条插值处理后的有效手势数据进行假波峰波谷处理,生成样本手势数据。
最后,由于有效手势数据中存在假波峰波谷,需要识别它们并进行处理。首先寻找三个连续的波峰或波谷,假设为p1,p2,p3。如果|p1-p2|>pthreshold并且|p2-p3|>pthreshold,pthreshold为假波峰波谷阈值,则认为存在假波峰或波谷p2。分别在p2两侧取两个点qi和qj,使用qi和qj的均值作为p2的值。取p2与p1的均值,得到从p1到p2第一个点的值,再取该点与p2的均值,得到从p1到p2第二个点的值,以此类推,得到p1与p2之间所有点的值。按相同的方法得到p2与p3之间所有的值。处理完成,从而生成手势数据样本。
本实施例中,通过对所述有效手势数据进行平滑处理;对所述平滑处理后的有效手势数据进行归一化处理;对所述归一化处理后的有效手势数据进行三次样条插值处理:对所述三次样条插值处理后的有效手势数据进行假波峰波谷处理,生成样本手势数据,从而提高了所生成的样本手势数据的有效性和准确性。
在一实施例中,如图6所示,所述移动终端还包括与所述目标天线相连的匹配网络,生成样本手势数据,基于用户对所述移动终端的握持手势状态从所述多个天线中匹配对应的目标天线之后,所述天线匹配方法具体还包括如下步骤:
S51:检测移动终端当前的通信信号的中心频率。
当移动终端的通信信号是单频信号时,移动终端可以通过利用频 率计直接测量出该单频信号的信号频率,该信号频率大小等于中心频率大小。当移动终端的通信信号是具有复杂频谱的电磁波信号时,移动终端可以采用频谱分析仪对该复杂频谱的电磁波信号进行频谱分析,然后获得通信信号的中心频率。
S52:基于中心频率生成控制信号,并将控制信号耦合至与目标天线相连接的匹配网络,匹配网络包括多个切换开关。
S53:响应控制信号控制匹配网络中的每一切换开关的状态,以使得目标天线的谐振频率与所述移动终端当前的通信信号相适配。
其中,匹配网络为用于对目标天线的谐振频率进行调节的网络。匹配网络包括多个并联连接的谐振路径,每一谐振路径包括一个切换开关和对应的LC串联谐振电路。每一LC串联谐振电路包括串联连接的电容和电感。通过对匹配网络中每一谐振路径的切换开关的状态进行控制,从而实现对匹配网络的阻抗进行调节,以达到对目标天线的谐振频率进行调节的目的。
由于控制信号为基于通信信号的中心频率所生成的用于控制与目标天线相连的匹配网络中的切换开关的信号,因此通过将控制信号耦合至与目标天线相连接的匹配网络,控制信号用于对匹配网络中每一谐振路径中切换开关的状态进行控制,从而实现对匹配网络的谐振阻抗进行调节,进而使得目标天线的谐振频率与通信信号的中心频率相同;以保证目标天线的谐振频率与所述移动终端当前的通信信号相适配。
本实施例中,通过检测移动终端当前的通信信号的中心频率,基于中心频率生成控制信号,并将控制信号耦合至与目标天线相连接的匹配网络,匹配网络包括多个切换开关;响应控制信号控制匹配网络中的每一切换开关的状态,以使得目标天线的谐振频率与所述移动终端当前的通信信号相适配;本实施例在确定了目标天线之后,通过调节标天线的谐振频率,从而使得目标天线的谐振频率与移动终端当前的通信信号相适配,以进一步提高通信信号的质量。
