对于终端上的各天线，这些天线在自由空间和靠近或接触终端的外部对象(例如，人体或其他物体介质)的过程中，由于所靠近或接触的对象的介电常数的影响，在使用过程中，由于被靠近或接触对象在天线近磁场的区域内，受自身天线效应的作用，会大大影响到天线辐射特性，对天线发射的射频信号的辐射效应产生折射、反射和阻挡。通过折射、反射和阻挡的信号会返回至该天线，从而对该天线的信号接收电路上的接收信号产生影响。这部分信号是影响天线回路上 的接收信号的信号参数的干扰信号，即，天线对外部对象会有一定的感应。而不同的外部对象、到外部对象的距离、不同的运动状态，对于终端不同种类的天线和天线参数所产生的影响都会不同。通过采集、统和计分析这些参数的变化，可利用这些参数的变化来实现触发对终端相应功能的控制。
终端本身包括一些部件，比如马达、扬声器、LCD、背光、触摸屏、USB模块、前置摄像头、后置摄像头等，同时还包括一些芯片，如GPS芯片、WIFI芯片、指纹识别芯片等。由于单板走线的限制，这些器件和芯片的供电线、时钟线、控制线和/或高速传输的数据线会和终端的主频线路靠近或相邻。因此在这些器件和芯片工作时，由于供电时钟或者数据的传输等因素，会对终端的通信频段(例如，包括但不限于：GSM(Global System for Mobile Communication)/WCDMA(Wideband Code Division Multiple Access)/CDMA(Code Division Multiple Access)/LTE(Long Term Evolution))的主、分集产生干扰和影响，从而导致终端的相应天线回路上的接收信号的电平产生变化。当有外界物体靠近或者接触终端的对应部位时，由于外界物体本身有一定的介电常数(或者一定的导电率)，终端的靠近或接触面相当于一个近场平板天线，因此器件或芯片工作时产生的噪声经由靠近终端天线区域的物体不断地反射，将原有的低噪干扰信号进一步加强。随着器件和芯片的工作周期出现规律性的跳变，跳变的干扰信号反射回的电磁信号又被耦合到终端的天线回路区域，形成二次混频，对终端的天线回路造成影响，从而使得在终端的天线回路上检测到的接收信号的电平值也出现规律性(例如周期性)变化。这种规律性的变化也可以用于实现触发对终端相应功能的控制。
根据本公开实施例，通过侦测在物体(也即待感应对象)接近或接触终端的过程中，终端上相应的感应对象所引起的终端内相应的天线回路上的接收信号的规律性变化，来实现对终端的接近感应式控制或接触感应式控制。
根据本公开实施例，终端上可具有多个天线回路，并且终端上可以有多个感应对象(例如，终端的各天线或终端内部对天线回路产 生干扰信号的部件)。此外，可以根据具体应用将终端外部的待感应对象设置为不同的对象。终端上的感应对象与终端外部的待感应对象配合时可以影响不同的天线回路，并且通过不同的配合方式(例如靠近、接触以及具体的靠近方式、接触方式等)对天线回路上的接收信号产生影响的程度也会不同。因此，根据本公开实施例，可以将终端的各待控制功能与相应的感应对象以及待感应对象关联，并且根据感应对象所能影响的天线回路来选择相应的天线回路。
根据本公开实施例，可以先设定终端的待控制功能(例如，解锁功能)以及触发对该待控制功能的控制的目标感应对象(例如，LTE天线)与目标待感应对象(例如，手)，以及与该目标感应对象和目标待感应对象对应的终端上的目标天线回路(例如，LTE天线回路)。设定的目标感应对象与设定的目标待感应对象在靠近或接触过程中，产生作用于目标天线回路的干扰信号，从而对目标天线回路上的接收信号的信号参数产生影响。可以通过设置好的目标感应对象和目标待感应对象预先进行靠近或接触，并在该过程中对目标天线回路上的接收信号进行实测来得到目标信号参数，其可以看成是基准参数。
图1为根据本公开实施例的终端控制方法流程示意图。
如图1所示，根据本公开实施例的终端控制方法可以包括步骤S101至S103。
在步骤S101处，对终端内的目标天线回路上的接收信号进行检测，并获取接收信号的信号参数。
在步骤S102处，判断获取的接收信号的信号参数与预设的目标信号参数是否匹配，如匹配，则转至S103；否则，转至S101。
在步骤S103处，触发对终端的待控制功能的控制。
通过上述过程，终端内的目标感应对象与终端外的目标待感应对象的配合可以影响目标天线回路上的接收信号，并且根据该接收信号的变化来实现对终端的控制，从而对终端的操控不再受到终端屏尺寸的限制，丰富了终端的控制方式，并提升了用户体验的满意度。
根据本公开实施例，在为待控制功能设置目标感应对象时，目标感应对象可以为目标天线回路上的天线和/或终端内的至少一个干 扰源部件。
当目标感应对象为目标天线回路上的天线时，该天线与外部的目标待感应对象(例如，用户的手其他物体)在靠近或接触过程中就会对目标天线回路上的接收信号产生影响。当目标感应对象为终端内的至少一个干扰源部件时，干扰源部件在工作时会产生噪声信号，且该噪声信号在外部的目标待感应对象的作用下被反射至目标天线回路的部件，以对该目标天线回路上的接收信号产生影响。
根据本公开实施例，目标待感应对象可以包括人体部位和终端的外部物体中的至少一个。
例如，目标待感应对象可以包括手、脸部中的至少一个，或者可以是人体的任意部位。此外，目标待感应对象可以包括桌面(包括各种材质或形状的桌面)、钱包、衣物口袋、电子设备中的至少一个。
根据本公开实施例，终端内的感应对象和终端外的目标待感应对象之间的配合方式可以是逐步靠近或者接触，此外接触还可以包括完全接触或部分接触。
根据本公开实施例，所检测的目标天线回路上的接收信号为通过将目标天线回路的信号发射电路发射的基准信号耦合至目标天线回路的信号接收电路的信号，即，目标天线回路可以通过自发自收来实现对于接收信号的接收，并获取接收信号的信号参数。根据本公开实施例，信号参数理论上可以是能反应外部的待感应对象和终端上的感应对象之间的配合情况的任何参数，例如，可以是噪声参数，也可以是接收信号的电平值。
根据本公开实施例，对目标天线回路上的接收信号进行检测时，可以在一个或多个预设频点上分别对目标天线回路上的接收信号进行扫描，从而获取相应的信号参数。
可以在至少一个预设频点上分别对目标天线回路上的接收信号进行M次扫描，并在所述至少一个预设频点上分别获取接收信号的M个电平值，M为大于等于1的整数。可以根据具体需求来设定预设频点个数以及在各预设频点上扫描的次数。
根据本公开实施例，当M等于1时，即，在所述至少一个预设 频点上对目标天线回路上的接收信号进行一次扫描，预设的目标信号参数可以包括在所述至少一个预设频点上的目标信号电平值，在此情况下，判断接收信号的信号参数与预设的目标信号参数是否匹配的步骤(即，步骤S102)可以包括：将在所述至少一个预设频点上分别获取到的接收信号的电平值与该预设频点上对应的目标信号电平值进行比较，并根据比较结果确定二者是否匹配。例如，可以根据二者之差是否在预设范围内，或者根据二者的大小关系等来确定二者是否匹配。
根据本公开实施例，当M大于1时，即，在所述至少一个预设频点上对目标天线回路上的接收信号进行至少两次扫描，并且获取到至少两个接收信号的电平值时，预设的目标信号参数可以包括在所述至少一个预设频点上的至少两个目标信号电平值，在此情况下，判断接收信号的信号参数与预设的目标信号参数是否匹配的步骤(即，步骤S102)可以包括：将根据至少两个接收信号的电平值构成的电平波动变化图与根据所述至少两个目标信号电平值构成的目标电平波动变化图进行比较。
可以根据具体需求选用单个或多个电平值进行比较，或者通过电平波动变化图进行比较。采用多个电平值进行比较或采用电平波动变化图进行比较时，还可以在一定程度上反映出终端内的感应对象与外部待感应对象之间的移动趋势或轨迹状态等。
根据本公开实施例，在目标天线回路上对接收信号进行扫描时，为了避免其他干扰信号的干扰导致检测结果不准确的问题，在对终端内的目标天线回路上的接收信号进行检测之前(例如，可以是在终端开机时，或者在终端检测到自身位置有比较大的变化时)，根据本公开实施例的终端控制方法还可以包括：获取终端内部和外部的干扰信号；获取各干扰信号的谐波频率，并判断各干扰信号的谐波频率是否在终端的工作频段范围内，如果谐波频率在终端的工作频段范围内，则将该工作频段范围内与该谐波频率对应频点标记为干扰频点，以避免在这些干扰频点上进行扫描。这样，在后续选择预设频点时，可以从工作频段范围未被标记为干扰频点的各频点中选择预设频点。
例如，首先进行外界干扰扫描，对终端所处的环境噪声做一个全频段扫描，判断哪些频段干扰比较强烈，哪些频段没有干扰。通过控制，使终端进入接收电平自测模式，对全频段全信道做快速自检。这个操作可以在终端重启后执行，也可以在终端移动到了某一个地区后发现经、纬度变化较大后执行。该操作可以在后台自动启动并执行。例如，当前环境中2100MHz或者850MHz是公网信道，在其中的某些信道(例如，中间信道)存在较大干扰，而这些干扰会对后续接收信号和噪声的检测造成较大干扰和波动，不利于接收信号的电平稳定性的检测。因此，可将这些测试到的不稳定或有不规则调整接收信号跳变的频段及频点记录下来。在后续的感应扫描自测中，自动避开这些频段，并跳过干扰频点，以得到一个稳定的检测条件。
根据本公开实施例，除了标记干扰频点避以外，还可以通过硬件排除干扰。例如，当检测到有干扰时，控制天线开关将射频通路切换至其它非干扰频段，并在非干扰频段上进行收发通讯和感应检测。此外，在每个射频开关后连接带通滤波器组，以对外界的宽频噪声进一步限制和滤波，使得进入终端的天线的外界信号不是干扰信号。
通过排除干扰信号，可以使得检测更加稳定可靠，并且使得以此为依据的控制操作更为精确，可进一步提升用户体验的满意度。
图2为根据本公开另一实施例的终端控制方法流程示意图。
本实施在前述实施例的基础上，以终端为手机为例，提供了终端控制的完整过程的示例，以更好的理解本公开。
参见图2，根据本公开另一实施例的终端控制方法可以包括步骤S201至S212。
在步骤S201处，开启根据本公开的控制模式，其包括开启相关部件和天线的自适应感应控制识别模式，并关联相关的手机操作、功能、无线设置及通讯等。
在步骤S202处，用户在首次使用本系统时，可以根据需求，设置需要由人体或物体等待感应对象接触或靠近的天线位置，以及需要感应的手机部件(可以是天线或干扰源部件)。
在该步骤中，用户可以设置需要在灭屏状态或亮屏状态下执行 的手机功能、天线区域(即，天线回路)、人体或其他接触物体的种类、需要检测的感应部件或天线等，此外，还可以设置与感应识别相关的参数(例如，电平值以及相关的电平值阈值)和敏感度等。敏感度用于实现精度控制，例如，可以设置检测到的参数(例如，电平值)与预设的目标参数(例如，电平阈值)之差的范围，从而对控制的精度进行设置。
例如，可以通过交互界面由用户设置哪些功能需要通过本公开提供的控制方式进行控制，其包括但不限于：解锁、加锁、来电接听、静音、震动模式、飞行模式、蓝牙互连、WIFI互连、GPS定位开启等。此外，可以将上述这些待控制功能与目标天线回路、目标感应对象以及外部的目标待感应对象(例如，人体或其他接触物体)一一对应地进行设置。
可以通过设置与感应功能对应的手机天线的位置来选择选使用哪些天线回路，例如，左下角LTE主天线、右下角CDMA主天线、左上角分集天线、右上角GPS天线、右侧边WIFI和蓝牙天线、中部NFC天线等。
待接触物体(即，待感应对象)可以包括但不限于：桌面、人手、钱包、口袋、电子设备(例如，另一手机、可穿戴智能设备、蓝牙耳机等)。
感应对象(即，手机上的感应部件)可以包括手机内的马达、LCD、前置摄像头、后置摄像头、扬声器、指纹芯片、GPS芯片、WIFI芯片、射频蜂窝芯片等，也可以是天线回路上的天线。
在步骤S203处，手机调用屏蔽环境下各天线及部件工作和关闭模式下的接收噪声参数和接收信号电平参考值模型，进行自校准。
在S204处，手机开启频段和信号扫描模式，侦测外界无线电通讯信号或其他干扰信号，同时获取手机内部或外部的干扰信号，根据各干扰信号的工作频率计算各干扰信号的多次谐波频率，并将落入采集工作频段内的谐波频率标记为干扰频点。
在射频信号的工作过程中，会存在两次或多次谐波、交调信号等，还会存在传导杂散和辐射杂散信号，对于接收信号，在发送和接 收之间会存在混频干扰。因此，在实际感应控制中，需要排除外界和手机本身的噪声干扰产生的影响。
在步骤S205处，可以通过，例如，手机的干扰屏蔽模块将手机的天线开关和带通滤波组切换到抗干扰频段，同时在选定频段上实现全信道扫描侦测，对于有影响的信道进行跳频处理。干扰屏蔽模块可通过两部分来完成外界干扰的屏蔽。首先是硬件部分，当检测到有干扰时，控制天线开关将射频通路切换其它非干扰频段，并在非干扰频段上进行收发通讯和感应检测。此外，在每个射频开关后连接带通滤波器组，以对外界的宽频噪声进一步限制和滤波，使得进入手机天线的外界信号不是干扰信号。其次是软件屏蔽部分，经过在全信道或局部信道进行扫描，将已知的外界干扰信道或频点过滤掉，同时将测试信道的多次谐波频点也过滤掉，使得在感应扫描中，只扫描干净频点或信道。
在步骤S206处，设置对应的电平值、频段、信道、带宽、混频模式、接收电平的跳变点或变化值等，即，选择预设频点并设置采集参数。
在步骤S207处，对待感应对象接触或靠近感应对象后，对应部件打开和关闭时的接收电平的变化值进行采集。
可以选择最敏感的部件来进行电平变化值的采集。对应与天线频点及部位来检测采集是否成功，如果采集成功且可识别，则可进入感应工作模式，如果采集失败，则可提示重新采集。
在步骤S208处，采集的参数在原始参数模型上进行修正，将其转化为对应位置和部件的接收值目标参数，并存储在手机的存储器中。可以采集接收信号的电平值，并将采集的电平值作为目标电平值进行保存，以供后续匹配。
在步骤S209处，采集完成后，可以启用感应控制模式，即，可以通过感应操作来执行对应的待控制功能。
在步骤S210处，当用户或物体靠近或接触手机后，对手机的相应目标天线回路上的接收信号的电平值进行检测。
在步骤S211处，比较采集到的电平值与存储的目标电平值，如 果两者一致或者在规定阈值范围内，则将对比结果传输给手机的基带模块，如果两者不一致或者超出范围，则不进行响应或给出提示。
在步骤S212处，根据基带模块的处理结果，实现对应的手机功能的控制，即，调用设置的相关功能。
图3为根据本公开实施例的终端结构示意图。
如图3所示，根据本公开实施例的终端可以包括设置模块31、信号检测模块32和控制模块33。
设置模块31用于设定终端的待控制功能(例如，锁屏功能)，触发对该待控制功能的控制的目标感应对象(例如，LTE天线)和相应的目标待感应对象(例如，手或电子设备)，以及目标感应对象和目标待感应对象在终端上对应的目标天线回路(例如，LTE天线回路)。设定的目标感应对象与设定的目标待感应对象在靠近或接触过程中，产生作用于目标天线回路的干扰信号，从而对目标天线回路上的接收信号的信号参数产生影响。可以通过设置好的目标感应对象和目标待感应对象预先进行靠近或接触，并在该过程中对目标天线回路上的接收信号进行实测来得到目标信号参数，其可以看成是基准参数。

在为待控制功能设置目标感应对象时，设置模块31可以将目标感应对象设置为目标天线回路上的天线和/或终端内的至少一个干扰源部件。
目标待感应对象可以包括人体部位和终端的外部物体中的至少一个。
例如，目标待感应对象可以包括手、脸部中的至少一个，或者可以是人体的任意部位。此外，目标待感应对象可以包括桌面(包括各种材质或形状的桌面)、钱包、衣物口袋、电子设备中的至少一个。
目标天线回路可以为通讯天线回路(包括但不限于： WCDMA/CDMA/GSM/LTE天线回路)或功能天线回路(包括但不限于：GPS/WIFI/蓝牙天线回路)。
干扰源部件可以包括但不限于：摄像头、扬声器、马达、背光模组、触摸屏、USB模块、GPS芯片、WIFI芯片、指纹识别芯片、蓝牙芯片中的至少一个。可以选择一个或多个干扰源部件。
所检测的目标天线回路上的接收信号为通过将目标天线回路的信号发射电路发射的基准信号耦合至目标天线回路的信号接收电路的信号，即，目标天线回路可以通过自发自收来实现对于接收信号的接收，并获取接收信号的信号参数。信号参数理论上可以是能反应外部的待感应对象和终端上的感应对象之间的配合情况的任何参数，例如，可以是噪声参数，也可以是接收信号的电平值。
信号检测模块32可以设置为在至少一个预设频点上分别对目标天线回路上的接收信号进行M次扫描，并在所述至少一个预设频点上分别获取接收信号的M个电平值，M为大于等于1的整数。
例如，信号检测模块32在一个预设频点上对目标天线回路上的接收信号进行M次扫描，并在该预设频点上获取接收信号的M个电平值。又例如，信号检测模块32在至少两个预设频点上分别对目标天线回路上的接收信号进行M次扫描,并在所述至少两个预设频点上分别获取接收信号的M个电平值。
信号检测模块32可以根据具体需求来设定预设频点个数以及在各预设频点上扫描的次数。
当M等于1时，即，在所述至少一个预设频点上对目标天线回路上的接收信号进行一次扫描，预设的目标信号参数可以包括在所述至少一个预设频点上的目标信号电平值，在此情况下，控制模块33设置为将在所述至少一个预设频点上分别获取到的接收信号的电平值与该预设频点上对应的目标信号电平值进行比较，并根据比较结果确定二者是否匹配。例如，可以根据二者之差是否在预设范围内，或者根据二者的大小关系等来确定二者是否匹配。
当M大于1时，即，在所述至少一个预设频点上对目标天线回路上的接收信号进行至少两次扫描，并且获取到至少两个接收信号的 电平值时，预设的目标信号参数可以包括在所述至少一个预设频点上的至少两个目标信号电平值，在此情况下，控制模块33设置为将根据至少两个接收信号的电平值构成的电平波动变化图与根据所述至少两个目标信号电平值构成的目标电平波动变化图进行比较。
控制模块33可以根据具体需求选用单个或多个电平值进行比较，或者通过电平波动变化图进行比较。采用多个电平值进行比较或采用电平波动变化图进行比较时，还可以在一定程度上反映出终端内的感应对象与外部待感应对象之间的移动趋势或轨迹状态等。
图4为根据本公开另一实施例的终端结构示意图。
参见图4，根据本实施例的终端还可可以包括干扰处理模块34。在信号检测模块32对终端内的目标天线回路上的接收信号进行检测之前(例如，可以是在终端开机时，或者在终端检测到自身位置有比较大的变化时)，干扰处理模块34获取终端内部和外部的干扰信号和各干扰信号的谐波频率，并判断各干扰信号的谐波频率是否在终端的工作频段范围内，如果谐波频率在终端的工作频段范围内，则将该工作频段范围内与该谐波频率对应频点标记为干扰频点，以避免在这些干扰频点上进行扫描。这样，在后续选择预设频点时，可以从工作频段范围未被标记为干扰频点的各频点中选择预设频点。
干扰处理模块34可以通过前述实施例中描述的方式来排除干扰信号，在此不再赘述。
图5为根据本公开又一实施例的终端结构示意图。
本实施例在前述实施例的基础上，仍以终端为手机为例，对终端的结构进行进一步示例说明。
如图5所示，根据本实施例的手机可以包括：用户设置模块51(对应前述实施例中的设置模块31)、外界干扰扫描模块52、干扰屏蔽模块53(外界干扰扫描模块52和干扰屏蔽模块53对应前述实施例中的干扰处理模块34)、接收电平自测模块54、部件噪声采集模块55(接收电平自测模块54和部件噪声采集模块55对应前述实施例中的信号检测模块32)、噪声对比识别模块56、自适应感应控制模块57(噪声对比识别模块56和自适应感应控制模块57对应前 述实施例中的控制模块33)、基带芯片模块58、射频芯片模块59，移动设备存储模块510、部件模块511(即，可以设置为感应对象的干扰源部件)、天线模块512(包括但不限于通讯天线和功能天线)以及感应操作指令模块513。
用户设置模块51用于提供设置交互界面，用户可以设置需要在灭屏状态或亮屏状态下执行的手机功能、天线区域(即，天线回路)、人体或其他接触物体的种类、需要检测的感应部件或天线等，此外，还可以设置与感应识别相关的参数(例如，电平值以及相关的电平值阈值)和敏感度等。敏感度用于实现精度控制，例如，可以设置检测到的参数(例如，电平值)与预设的目标参数(例如，电平阈值)之差的范围，从而对控制的精度进行设置。
用户通过用户设置模块51提供的交互界面可以进行的设置如前述实施例所述，在此不再赘述。
外界干扰扫描模块52和干扰屏蔽模块来53彼此相邻，并且可以通过参考图2的步骤S204和步骤S205所描述的操作来排除外界和手机本身的噪声干扰的影响，屏蔽外界干扰信号、干扰频率及其谐波，使得当前在目标天线回路上对接收信号的扫描操作是在非干扰的频点和信道上进行的，外界干扰扫描模块52和干扰屏蔽模块来53的具体操作方式在此不再赘述。
接收电平自测模块54与射频芯片模块59和部件噪声采集模块55相连，并且用于对目标天线回路上的调制和非调制信号的接收频点扫描，同时还用于采集接近或接触人体或其他物体后目标天线回路上接收信号的电平信号变化。通过控制射频芯片模块59中接收机进行扫描，以使手机切换到某一个制式、频段、带宽、起始和终止频点或信道后，接收电平自测模块54进行自发自收的回路扫频操作。接收电平自测模块54首先设置基本的信号强度电平(例如，-90dB)。对于不同的制式(例如，WCDMA/CDMA/GSM/LTE)或其他无线传输方式(例如，WIFI/BT/GPS),接收电平自测模块54扫描的基本电平是不一样的。当检测不出接收信号或当前底噪太大时，可以将基本电平调高或调低，调节范围例如在-50dB到-110dB之间。对于GPS信道，基 本电平可以被调整到更低范围，例如，-110dB到-150dB之间。接收信号的电平可以为主集天线电平，也可以为分集天线电平。扫频信号可以是载波信号，也可以是非载波信号。扫描速度可以通过扫描步进和扫描频点数来调整。
在扫描过程中，扫描频点以及采集样本数量可以根据采集到的值的变化来自动选取或做平均处理，以防止不稳定因素或异常外界干扰因素。如果两次采集同一个频点的接收信号的电平值一致，说明采集稳定，不需要进行第三次扫描。如果两次扫描中关键采集点差值较大，则进行更多次数扫描，直到得到规则信号值。
接收电平自测模块54通过目标天线回路的发射信号电路块给手机的前端灌入基本电平信号，手机将该信号经过带通滤波、LNA放大后经过可变频率本振器混频得到对应频段的中频信号，中频信号经过后级滤波及AD转换后进入可变增益放大器达到接收信号的电平采集上报模块。接收电平自测模块54可通过不断调节本振频率，得到不同的中频信号，再采集各频点的接收电平值。
当手机在对应模式下待机或工作并且手机内的干扰源部件处于睡眠模式下时，可采用天线回路上的天线作为感应对象。当手机接触人手、人体、桌面，或靠近其他平台或装置时，接收电平自测模块54检测在接触或靠近之前和之后的手机天线对应区域的接收信号的电平变化值。接收电平自测模块54对感应前后的某一频段进行全信道或局部信道扫描，识别出接收电平波动变化图，或电平阈值变化。当波形合乎识别特征时，或者当某一个或几个频点的接收电平变化到某一个阈值范围时，即可触发对应的感应操作。
部件噪声采集模块55与接收电平自测模块54、噪声对比识别模块56和移动设备存储模块510相连，并且用于接收电平自测模块54检测到的电平值的变化。部件噪声采集模块55将电平值的变化转换为对应部件及频点的噪声参数值，并将噪声参数值存储到移动设备存储模块中510。部件噪声采集模块55可以省略。
当手机在对应模式下待机或工作并且手机部件处于工作状态时，例如，刚好有来电，手机扬声器振铃或马达震动，此时将手机放置到 对应平台或人手接近，部件噪声采集模块55启用接收电平自测模块54，以扫描对应频段下的接收信号。将接触后的扫描值和接触前的扫描值相比较，识别出接触前后的接收电平波动变化图，或电平阈值变化，当波形合乎部件启动后的识别特征时，或者当某一个或几个频点的接收电平变化到某一个阈值范围时，即可触发对应的感应操作。
噪声对比识别模块56与部件噪声采集模块55和自适应感应控制模块57相连，并且用于将采集到的信号参数(例如，电平值或噪声参数)与模型存储参数(即，对应的目标信号参数)进行对比，如果两者一致或者在规定阈值范围内，则将对比结果传输给自适应感应控制模块57，如果不一致或者超出范围，则不进行响应或给出提示。
由于手机硬件本身及部件本身会有一定的底噪，所以噪声对比识别模块56首先需要将没有物体或人体接近的噪声从采集到的结果中减去，只剩下物体或人体接近后的增量变化差值，然后就此增量变化差值进行对比识别判断。
另外，由于检测过程中会存在误差，所以检测得到的接收值和手机中存储的参数模型值会有一定的差异，因此在参数对比时，可以采取一定阈值的波动范围，只要在此阈值范围内的检测数据，都是有效，从而会启动对应的指令操作。
自适应感应控制模块57与用户设置模块51、基带芯片模块58及其他感应采集和识别模块相连，并且用于感应检测到的自适应控制。自适应感应控制模块57还用于不同操作指令的感应控制。自适应感应控制模块57用于完成感应控制的各模块的协调控制，并将控制指令发送给基带芯片模块58。
基带芯片模块58和自适应感应控制模块57及用户设置模块51相连，并且用于接收用户设置模块51的指令，并根据感应控制模块57的控制指令来控制手机各模块完成对应操作。基带芯片模块58还用于检测各部件的启动和停止以及采集过程中接收感应控制，以控制各部件工作。
射频芯片模块59与接收电平自测模块及天线模块512相连，并且用于外界干扰信号的扫描及侦测。射频芯片模块59和天线模块512 及射频前端电路一起，形成封闭的天线回路，以实现接收信号电平的检测。
移动设备存储模块510与接收电平自测模块54和部件噪声采集模块55相连，并且用于存储用户或其他物体接触或接近手机天线或其他部位之前和之后的天线及部件噪声的变化参数及模型数据。
部件模块511与部件噪声采集模块55相连，并且是可以设置为感应对象的干扰源部件。部件模块511可以包括手机内的马达、LCD、前置摄像头、后置摄像头、扬声器、指纹芯片、USB模块、GPS芯片、WIFI芯片、射频蜂窝芯片及天线等。这些器件和芯片在工作过程中，容易受到外界触控的影响，从而导致手机内的特定天线回路上的接收电平产生规律性变化。
天线模块512与射频芯片模块59相连，并且用于移动通讯设备的信号的接收和发射和外界电磁干扰信号的采集，此外，天线模块512还可用作产生噪声影响的人体或物体的感应媒介。
感应操作指令模块513与基带芯片模块58相连，并且用于手机各功能模块的感应控制，例如，启动某一应用程序，开启或关闭无线功能模块(例如，蓝牙、WIFI、GPS等)、无线功能的连接或断开、手机设置进入特定设置模式(例如，接听模式、飞行模式、静音模式)等。此外，感应操作指令模块513也可以控制手机的某一功能，例如，手机解锁、关闭屏幕、点亮屏幕等。
基于图5所示的本公开实施例的终端，对一些应用场景下的检测结果进行了测试。
图6为示出了用户的手靠近根据本公开实施例的终端的示意图，图7示出了在图6所示场景中的接收电平的波动示意图。
当所有的手机部件都处于休眠状态，而手机的通讯天线或无线天线(例如，GSM、WCDMA、LTE、WIFI、BT和GPS天线)处于待机状态，当手靠近手机不同的天线或者手握并以掌心覆盖不同的天线时，由于人体的导体作用，对地形成了接地环路，对天线的辐射信号产生反馈。手机自身采集到的接收电平值(即，目标天线回路上的接收信号的电平值)在手靠近或接触之前和之后会发生很大的变化。在图7 中，71为手接近手机时天线接收回路上的接收电平值，72为电平参考值，73为低噪非接触时接收回路上的接收电平值。
表1示出了在不同的感应场景下的接收感应值：
表1
Figure PCTCN2018084615-appb-000001
手接近或接触手机的对应区域可以产生接收参数的变化，并且通过将参数的变化与预存或标准参数模型相比较可检测到是否有手接近或接触手机。通过不同变化幅度阈值的判断，可进一步识别出不同的接近方向和距离，进而映射至感应指令操作，以控制手机的相应功能。
当然，此实例不光局限于手，人体其他部位也同样适用。
图8示出了根据本公开实施例的终端处于桌面内的示意图，图9示出了根据本公开实施例的终端的天线部分处于桌面外的示意图，并且图10示出了在图8和图9所示场景中的接收电平的波动示意图。
当手机放置在桌面或某一个物体上时，手机天线完全放置在平台上，相对于手机某一区域悬空放置，手机的接收噪声会处于两种状态。
如图8所示，手机81完全处于桌面82内。如图9所示，手机81的一部分处于桌面82内。如图10所示，1001为天线位于桌面82内时的接收电平变化示意图，1002为天线位于桌面82外时的接收电平变化示意图。
图11示出了根据本公开实施例的终端在桌面上的几种不同方式所对应的接收电平的波动示意图。
当手机81放置在桌面82上时，天线朝向空中和LCD朝向空中这两种放置方式也会得到两种不图的接收电平及噪声干扰值。如图11所示，1101为天线位于桌面外放置时的接收电平变化示意图，1102为手机背面向上放置于桌面时的接收电平变化示意图，1103为目标接收电平参考值示意图，1104为手机正面朝上放置于桌面时的接收电平变化示意图。
因此，对于手机的不同放置方式以及不同的朝向，可检测到不同的接收参数值，即，可以通过手机的不同放置方式实现感应控制指令的激活和关闭。
图12示出了根据本公开实施例的终端的马达作为感应对象时的接收电平的波动示意图。
当来电或者闹铃时，手机的内置马达会周期性地震动。这个时候，用户不用激活电源键，也不用点亮手机屏幕或做其他触控操作，只需要将手机放置在不同的位置，或者用手接近手机上方，或者采用不同手握的方式，或者放置在不同的平台上，感应控制模块57(参见图5)就会检测到不同形式和幅值的周期性变化的接收波形。
如图12所示，1201为手机放置在桌面上马达震动时的接收电平变化示意图，1202为手机天线悬空放置在桌面上马达震动时的接收电平变化示意图，1203为手握手机并且手机天线悬空时的目标接收电平参考值示意图，1204为手握手机下部并且马达振动时的接收电平变化示意图。
通过不同脉冲波形和幅度的检测，可检测出不同的接近或放置方式。可以将每个方式和手机的某一个功能相关联，例如，将1201所表示的方式设置为自动接听，将1202所表示的方式设置为拒接，将1203所表示的方式设置为静音，并且将1204所表示的方式设置为进入飞行模式。因此，当用户将手机放置在不同位置，或者使用不同的手握方式握住手机时，可以自动触发手机进入对应的功能和模式中，从而实现智能自动感应控制。
图13示出了根据本公开实施例的终端的指纹芯片作为感应对象时的接收电平的波动示意图。其基本原理与结合图12所描述的示例 实质上相同，在此不再赘述。
图14示出了根据本公开实施例的终端摆动示意图，图15示出了在图14所示的终端摆动过程中的接收电平的波动示意图。
手机可以处于亮屏或灭屏状态，手机LCD主频时钟对接收信号有噪声干扰的影响，并且光驱动芯片对接收信号也有噪声干扰的影响。这种噪声干扰有辐射效应，当有人手靠近或接触时会产生反射，进而将干扰信号串扰到手机的接收回路。
这个时候，用户不用点击手机的任何按钮或按键，只需要将手机放置在不同的位置，或者用手接近手机上方，或者采用不同手握的方式，或者放置在不同的平台上，感应控制模块57(参见图5)就会检测到某一个低频的某一个信道或频点(例如877.6MHz)的主集或分集在参考电平下的变化阈值，通过和预存的参考阈值相比较，可以得出当前的放置方式或手握方式，进而实现手势识别。表2示出了在不同的感应场景下的接收感应值：
表2
Figure PCTCN2018084615-appb-000002
这个时候，用户还可以在不同的手握方式下握住手机顶部或底部并进行摆动操作(如图14所示)，即可得到其赋值周期性递减的脉冲曲线(如图15所示)，以便于用户的自定义设置。如图14所示，当用户手握手机底部使手机反复摆动时，就会得到如图15所示的幅值渐变小的接收波动信号，以此和预定义的波形参数相对照，可触发对应的感应功能指令。
当两个手机需要互联通讯时，例如，建立蓝牙连接、WIFI直连、热点共享、NFC手机支付等，只需要将两个手机相互靠近，通过两个手机本身内部的干扰源部件或天线的互扰来影响接收信号的变化，可 判断出当前两个彼此靠近的手机的方向、距离和运动趋势，进而和对应的感应控制指令相链接，以实现两个终端之间的感应功能控制。
图16示出了根据本公开实施例的两个终端彼此同向靠近的示意图，图17示出了根据本公开实施例的两个终端彼此背对背靠近的示意图，图18示出了根据本公开实施例的两个终端彼此同向逐渐靠近的示意图。在图18中，B1、B2、B3分别对应于三个不同的位置。终端A固定在某一个位置后，终端B分别处于贴近终端A放置的B1位置、移动了0.5CM的B2位置以及移动了1CM的B3位置。表3示出了在不同的感应场景下的接收感应值：

本公开提供了一种可以悬浮或接触地感应控制终端或穿戴设备的方法。通过检测终端的部件和外部的接触物体之间的相互耦合对终端的天线回路产生的影响，来判断识别用户的操作，并和预先采集的各种人-机、机-物、机-机感应模型相比较，以实现各种感应指令操控。
显然，本领域的技术人员应该明白，上述本公开实施例的各模块或各步骤可以用通用的计算装置来实现，这些模块或步骤可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上。这些模块或步骤可以用计算装置可执行的程序代码来实现，从而，可以将程序代码存储在计算机存储介质(ROM/RAM、磁碟、光盘)中由计算装置来执行，并且在某些情况下，可以以不同于此处的顺序执行所 示出或描述的步骤，或者将这些模块或步骤分别制作成各个集成电路模块，或者将这些模块或步骤中的多个模块或步骤制作成单个集成电路模块来实现。所以，本公开不限制于任何特定的硬件和软件结合。
