下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完
整的传达给本领域的技术人员。
实施例一
如图1所示，本公开的实施例提供了一种移动终端的检测方法，其方法包括以下步骤：
步骤11：接收预定范围内移动终端发射的射频信号。
其中，移动终端通过发送射频信号和接收射频信号实现与其他设备的无线通信，例如：通过发送上行射频信号与基站进行通信，发送蓝牙标准的射频信号与蓝牙设备进行通信，发送WIFI信号实现WIFI通信等。其中不同的无线通信对应的射频信号的发射频率不同。以上行信号为例，不同的通信制式下，例如：GSM、GPRS、EDGE、LTE、UMTS或TDSCDMA等通信制式，移动终端发射的上行信号的上行发射频段不同。
步骤12：根据预先设定的滤波频段对射频信号进行滤波，得到滤波频段内的射频信息。
由于不同的通信制式下移动终端发射的上行信号的上行发射频段不同，因此，可将预先设定的滤波频段设置为不同通信制式下移动终端的上行发射频段。这样，在根据预先设定的滤波频段进行滤波后，可得到上行发射频段内的射频信号。可将接收到的射频信号分为两路，一路进行正常的通信处理，另一路进行本实施中移动终端检测的处理。其中，正常的通信处理具体包括：射频信号放大、滤波、调制解调以及基带处理，即移动终端在接收到射频信号后分为两路，对其中一路射频信号进行功率放大，对放大后的射频信号进行滤波以得到当前通信制式下的下行射频信号，对该下行射频信号进行解调处理得到一基带信号，对该基带信号进行基带处理得到下行信息，完成正常的通信处理流程。而对移动终端进行检测具体包括：射频信号放大、滤波和功率分析处理，即移动终端在接收到射频信号后分为两路，对另一路射频信号进行功率放大，对放大后的射频信号进行滤波以得到不同通信制式下的上行射频信号，最后对该上行射频信号进行功率分析。
步骤13：若滤波频段内的射频信号的功率强度超过预设阈值，则确定预定范围内存在移动终端。
其中，这里所说的功率强度的预设阈值的设定与预定范围的大小相关，一般地，预定范围越小所设定的功率强度的预设阈值越大，反之，预定范围越大所设定的功率强度的预设阈值越小。
这样，移动终端接收周围环境中的射频信号并对其进行滤波，由于不同通信制式所采用的上行射频频段不同，因此可识别预设范围内不同通信制式下的移动终端，检测滤波后的射频信号的功率强度是否超过预设阈值，以确定相应的预定范围内是否存在移动终端。由于采用无线射频信号进行检测，因此检测电路可集成于移动终端内，以实现移动终端的探测能力。
为了保护用户的人身和财产安全，在步骤13之后该方法还包括：检测与移动终端之间的安全距离；当安全距离低于预设距离值时，生成一提示用户注意安全的告警信息。其中，检测与移动终端之间的安全距离可通过检测射频信号的功率强度实现，功率强度越大，说明与检测到的移动终端的安全距离越小，当功率强度超过最大阈值时，即检测到安全距
离低于预设距离值时，生成一提示用户注意安全的告警信息。例如，当用户处于偏僻地方时，可开启安全模式，以检测安全区域内是否有陌生人靠近，其检测方式可通过检测安全范围内是否有移动终端实现。或者，当用户正在进行支付操作或其他隐秘操作时，亦可通过开启安全模式检测安全区域内是否有陌生人靠近。当检测到安全范围内有人靠近时，生成一提示用户注意安全的告警信息，其中，该告警信息可以是文字提示、声音提示或其他引起用户注意的提示，以提高用户人身和财产安全。
在一些特殊场景中，如私密会议、飞机航行或防作弊考试中，为了保证工作正常进行，在步骤13之后，还包括：根据滤波频段内的射频信号的条数，确定移动终端的数目。具体地可根据滤波频段内射频信号的功率强度来确定射频信号的条数；其中，不同的移动终端发射的射频信号的功率强度不同。由于距离不同接收到射频信号的功率强度不同，因此可根据功率强度识别出预设范围内不同距离的移动终端，以实现对周围环境中的移动终端及其数量的检测和确定。
优选地，为了获得检测到的移动终端的具体位置，该方法在步骤13之后还包括：获取接收到的射频信号的功率强度和入射方向；根据射频信号的功率强度确定与对应的移动终端的间隔距离；根据入射方向和间隔距离，确定移动终端的位置信息。在确定移动终端的位置信息之后，还通过特定显示界面显示预设范围内的移动终端以及移动终端的位置信息，以直观的显示检测到的以终端中的位置信息。
