请参见图2所示，第二基准单元210包括第二超声波信号转换子单元2101和第二超声波信号接收子单元2102；第二超声波信号接收子单元2102用于接收发起终端10的第一超声波信号发送子单元1102发送的第一距离基准信息，并将其发送给第二超声波信号转换子单元2101，第二超声波信号转换子单元2101对接收到的第一距离基准信息进行处理（例如格式转换）后发送给第二控制单元230。
相应的，响应终端20也可设置发起发起终端10中的超声波转换子单元和超声波信号发送子单元，以向发起终端发送相应的距离基准信息；发起终端也可设置响应终端中响应的超声波转换子单元和超声波信号接收子单元接收响应终端发送的相关信息。即本实施例中的第一基准单元110和第二基准单元210之间的通信可以是单向的，也可以是双向的。
利用磁信道进行通信：
请参见图3，发起终端10的第一基准单元110包括第一磁信号发送子单元1103和第一发送线圈1104；第一磁信号发送子单元1103可用于将第一控制子单元130生成的第一距离基准信息转换成磁信号，然后通过第一发送线圈1104发送出去；本实施例的第一磁信号发送子单元1103可包括：编码模块、调制模块、驱动模块；磁信号经编码、调制、驱动通过第一发送线圈1104发送出去。
请参见图3响应终端20的第二基准单元210包括第二磁信号接收子单元2103和第二接收线圈2104；第二接收线圈2104用于接收发起终端10的第一发送线圈1104发送的第一距离基准信息，然后将第一距离基准信息发送给第二磁信号接收子单元2103，第二磁信号接收子单元2103对其进行格式转换等处理之后发送给第二控制单元230；第二控制单元230则根据该距离基准信息进行相应的操作。本实施例中的第二磁信号接收子单元2103可包括解码模块、解调模块、放大过滤模块；当第二磁信号接收子单元2103接收到第一距离基准信息时，可对其经过解码、解调、放大过滤后传输给第二控制单元230。
同样，在利用磁信道进行通信时，第一基准单元110与第二基准单元210之间的通信可以是双向的，也可以是单向的。当为双向通信时，请参见图4：
响应终端20的第二基准单元210在图3的基础之上，还可包括第二磁信号发送子单元2105和第二发送线圈2106；此时相应终端20的第二控制单元230还可用于生成第二距离基准信息；第二磁信号发送子单元2105则用于将第二距离基准信息转换成磁信号，然后通过第二发送线圈2106发送出去。
发起终端10的第一基准单元110则还包括第一磁信号接收子单元1105和第一接收线圈1106；第一接收线圈1106则用于接述响应终端20的第二发送线圈2106发送的第二距离基准信息，并将第二距离基准信息发给第一磁信号接收子单元1105，第一磁信号接收子单元1105接收到该消息后对其进行格式转换等处理之后发送给第一控制单元130；此时第一控制单元130则还可用于根据第二距离基准信息判断发起终端10与响应终端20之间的距离是否在预设范围内，并根据判断结果控制第一射频通信单元120与所响应终端20的第二射频通信单元220建立射频通信连接。
即本实施例中，响应终端20与发起终端10之间建立射频通信连接条件可设置为以下几种方式：
方式一：响应终端20接收发起终端10发送的距离基准信息，根据该信息判断二者之间的距离是否在预设范围内，是则建立射频通信连接；
方式二：发起终端10接收响应终端20发送的距离基准信息，根据该信息判断二者之间的距离是否在预设范围内，是则建立射频通信连接；
方式三：响应终端20接收发起终端10发送的距离基准信息，发起终端也接收响应终端发送的距离基准信息；当任意一方的根据接收到的距离基准信息判断出二者的距离在预设范围内时，建立射频通信；
方式四：响应终端20接收发起终端10发送的距离基准信息，发起终端也接收响应终端发送的距离基准信息；只有双方的根据接收到的距离基准信息都判断为二者的距离在预设范围内时，才建立射频通信。
另外，本实施例中，在判断发起终端10与响应终端20之间的距离是否在预设范围之内时，除了根据相应的距离基准信息判断之外，还可结合相应的对方反馈的相应应答信息进行判断，以提高判断的准确率，进而提高通信的可靠性。下面以根据距离基准信息结合基准距离信息的响应消息为例进一步说明：
响应终端20的第二控制单元230在接收到第一距离基准信息后，还用于根据该第一距离基准信息生成第一距离基准信息的应答消息；第二磁信号发送子单元2105则还用于将第一距离基准信息的应答消息转换成磁信号，通过第二发送线圈2106发送出去；发起终端10的第一接收线圈1106则接收到第二发送线圈2106发送的第一距离基准信息的应答消，并将其发送给第一磁信号接收子单元1105，第一磁信号接收子单元1105对该消息进行处理之后，则将其发送给第一控制子单元130。第一控制子单元130则接收到了响应终端20发送的第二距离基准信息和第一距离基准信息的应答消；并根据响应终端20反馈的这两个信息计算发起终端10与响应终端20之间的距离是否在预设范围内。
同样，发起终端10的第一控制单元130在接收到第二距离基准信息后，还用于根据该第二距离基准信息生成第二距离基准信息的应答消息；第一磁信号发送子单元1105则还用于将第二距离基准信息的应答消息转换成磁信号，通过第一发送线圈1106发送出去；响应终端20的第二接收线圈2106则接收到第一发送线圈2106发送的第一距离基准信息的应答消，并将其发送给第一磁信号接收子单元1105，第一磁信号接收子单元1105对该应该消息进行处理之后，则将其发送给第一控制子单元130。第一控制子单元130则接收到了响应终端20发送的第二距离基准信息和第一距离基准信息的应答消；并根据响应终端20反馈的这两个信息计算发起终端10与响应终端20之间的距离是否在预设范围内。
本实施例中，当采用磁信道这种实现方式时，利用发起终端10和响应终端20的喇叭和麦克风实现，例如，对于发起终端10，可将其第一发送线圈1104设置在其喇叭中，将其第一接收线圈1106设置在其麦克风中；第一发送线圈1104和第一接收线圈1106除了能实现上述功能外，还可维持喇叭和麦克风的正常功能；对应的，对于响应终端20，可将其第二发送线圈2104设置在其喇叭中，将其第二接收线圈2106设置在其麦克风中。相应的，对于发起终端10，可将其第一发送线圈1104设置在其麦克风中，将其第一接收线圈1106设置在其喇叭中；第一发送线圈1104和第一接收线圈1106除了能实现上述功能外，还可维持喇叭和麦克风的正常功能；对于响应终端20，可将其第二发送线圈2104设置在其麦克风中，将其第二接收线圈2106设置在其喇叭中。值得注意的是，本实施例中各终端的发送线圈和接收线圈不局限于设置在各终端的喇叭和麦克风之中，而是可设置在终端中所有自带线圈的元器件中。这种设置方式不需要在终端上额外增加发送线圈或是接受线圈，可降低射频通信的成本，提高用户体验的满意度。
值得注意的是，本实施例中发起终端10和响应终端20建立射频通信之后，发起终端10仍可按照一定的规律（例如定时或随机）向响应终端20发送第一距离基准信息；响应终端20的第二控制单元230仍可根据该距离基准信息判断通信过程中发起终端10与其之间的距离是否超出预设范围；如是，则控制响应终端20的第二射频通信单元220与发起终端10的第一射频通信单元120断开射频通信连接。同样，发起终端10的第一控制单元130在通信过程中也可按上述方式根据响应终端20发送的第二距离基准信息进行上述检测过程。
本实施例中的第一射频通信单元120和第二射频通信单元220可以为WIFI无线通信单元、蓝牙无线通信单元或者超宽带无线传输UWB（Ultra
Wideband，超宽带无线传输）单元中的至少一种，也可为RFID-SIM单元或RFID-SD单元。第一射频通信单元120和第二射频通信单元220的工作频点可以是2302.4GHz
、433MHz、900MHz、5.8GHz、60GHz等。
本实施例中，发起终端和响应终端具体可为计算机、个人数字助理PDA、手机、数码相机、数码摄像机、电子阅读器、音视频播放装置或数码相框等智能终端，也可以是智能汽车或者带有提供数据交互功能的汽车、火车、飞机或者轮船等智能交通工具；即，本实施例中的通信***可以应用于手机和手机之间的通信、数码相机与数码相框之间的通信、电脑与手机之间、电脑与电子阅读器之间等各类智能终端之间的通信，以及通信终端与智能汽车、通信终端与提供数据服务的汽车、火车、飞机或者轮船等智能交通工具之间的通信，从而满足人们日益增长的信息需求，使得人们可以随时随地与周围的其他智能终端和/或带有提供数据服务的智能交通工具进行交互，可以更加方便快捷的获取数据信息。
应当理解是，本实施例中的通信***可以包括多个发起终端10和多个响应终端20，也可以包括一个发起终端和多个响应终端20。当通信***包括多个发起终端10和响应终端20时，多个发起终端10和响应终端20可以两两相互通信，也可以其中一个作为发起终端10，其他的则作为响应终端20与发起终端10进行射频通信。
实施例二：
为了更好的理解本发明，在实施例一的基础之上，下面结合具体的通信方法为了对本发明做进一步说明：
由与本发明的通信双方在通信过程中，至少一方可接收对方发送的距离基准信息，并根据该距离基准信息判断双方之间的通信距离是否在预设范围内，进而根据判断结果决定是否建立射频通信连接。另外，本实施例中距离基准信息的发送可采用超声波信息发送，也可采用磁信道发送，下面以采用磁信道发送的方式为例对本发明做进一步的说明。
设通信双方中的一方为发起方，发起方的通信终端对应上述发起终端，另一方为响应方，响应方的通信终端对应上述响应终端；本实施例中的发起方和响应方是根据通信过程中由谁先发起而定的；发起方和响应方之间的消息交互以及各通信方消息的处理分别由上述发起终端和响应终端中对应的功能单元实现。
请参见图5，其所示为响应方接收发起方发送的第一距离基准信息，根据该第一距离基准信息判断双方是否满足建立射频通信连接的流程示意图，具体如下：
步骤501：在设定时间到达时，发起方设置第一发送频点，根据设置的第一发送频点将其生成的第一距离基准信息通过磁信道发送给响应方；
步骤502：响应方在与第一发送频点相同的第一接收频点上接收发起方发送的第一距离基准信息；

步骤504：响应方与发起方建立射频通信连接；具体可为响应方直接向发起方发送建立射频通信连接的请求；发起方接收到该请求后，则与响应方建立射频通信连接。
本实施例中，第一距离基准信息还可包括发送第一距离基准信息的终端身份识别信息，该身份识别信息具体可为该终端的服务集标识SSID、该终端的物理地址、该终端的认证密钥中的至少一种；在上述步503中，判断出发起方与响应方之间的距离在预设范围内之后，在转至步骤504之前，还可包括根据第一距离基准信息包括的发起方身份识别信息，对发起方的身份进行鉴权的步骤，在鉴权成功时，才转至步骤504；否则，转至步骤501。
另外，在上述步骤504之后，发起方与响应方已经建立了射频通信连接，可通过建立的射频通信连接进行相应的数据交互。在该数据交互过程中，还可包括以下步骤：
发起方仍按照一定的规律（例如按设定的频率发送或随机发送）向响应方发送第一距离基准信息；
响应方仍按上述过程根据第一距离基准信息判断发起方与其之间的距离是否在预设范围内；如是，则保持射频通信连接；否则，与发起方断开建立的射频通信连接。
请参见图6，其所示为响应方和发起方分别向对方发送距离基准信息，根据对方发送的距离基准信息判断双方是否满足建立射频通信连接的流程示意图，具体如下：
步骤601：发起方设置第二发送频点，根据设置的第二发送频点将第一距离基准信息通过磁信道发送给响应方；响应方设置第三发送频点，根据设置的第三发送频点将第二距离基准信息通过磁信道发送给所述发起方，优选的，设置的第三频点与上述第二频点为不同的频点；应当理解的是，此处第一距离基准信息可第二距离基准信息的发送可以没有严格的时序限制；

步骤603：响应方根据接收到的第一距离基准信息判断发起方与其之间的距离是否在预设范围之内；发起方根据接收到的第二距离基准信息判断发起方与其之间的距离是否在预设范围之内；如发起方和响应方的判断结果都为是时，则转至步骤604；否则，转至步骤601；
步骤604：响应方与发起方建立射频通信连接；具体可为响应方和发起方分别对方发送建立射频通信连接的请求；收到对方发送的建立射频通信请求后，则与对方建立射频通信连接。
同样，在上述步603中，判断出发起方与响应方之间的距离在预设范围内之后，在转至步骤604之前，还可包括响应方和发起方分别根据第一距离基准信和第二距离基准信息包括的身份识别信息对发起方和响应方的身份进行鉴权的步骤，只有在双方都鉴权成功时，才转至步骤604；否则，转至步骤601。
另外，在上述步骤603中，也可设置为只要通信双方中的任意一方的判断结果为是时，则可直接转至步骤604。
同样，在上述步骤604之后，发起方与响应方已经建立了射频通信连接，可通过建立的射频通信连接进行相应的数据交互。在该数据交互过程中，还可包括以下步骤：
发起方和响应方仍按照一定的规律（例如按设定的频率发送或随机发送）向对方分别发送第一距离基准信息和第二距离基准信息；
响应方和发起方仍按上述过程根据第一距离基准信息和第二距离基准信息判断发起方与其之间的距离是否在预设范围内；如双方的判断结果为是，则保持射频通信连接；否则，与发起方断开建立的射频通信连接。
当然，在上述建立射频通信连接之后，也可只选择一方向另一方发送距离基准信息实现相应的检测即可
，例如设置发起方向响应方发送第一距离基准信息；响应方按照上述判断方式进行相应的判断即可。
图6所示的方法流程中，在步骤602中，响应方在与上述第二发送频点相同的第二接收频点上接收第一距离基准信息之后，还可包括通过其设置的第三发送频点向发起方发送第一距离基准信息的应答消息；发起方在与第三发送频点相同的第三接收频点上接收第二距离基准信息之后，还可包括通过其设置的第二发送频点向发起方发送第一距离基准信息的应答消息。相应的，在上述步骤603中，响应方可根据接收到的第一距离基准信息和发起方反馈的第二距离基准信息的应答消息判断发起方与其之间的距离是否在预设范围之内，具体可根据上述两消息的强度来判断；发起方可根据接收到的第二距离基准信息的和第一距离基准信息的应答消息判断发起方与其之间的距离是否在预设范围之内，具体也可根据上述两消息的强度来判断；这种判断方式可进一步提升判断结果的准确率。
请参见图7，当响应方和发起方分别向对方发送距离基准信息，根据对方发送的距离基准信息判断双方是否满足建立射频通信连接时，还可通过以下步骤实现：
步骤701：发起方开启其磁信号发送功能，关闭其磁信号接收功能，设置第四发送频点，根据:第四发送频点将所述第一距离基准信息通过磁信道发送给响应方；
步骤702：响应方开启其磁信号接收功能，在与第四发送频点相同的第四接收频点上接收第一距离基准信息；

步骤706：响应方与发起方建立射频通信连接。
同样，在上述步705中，判断出发起方与响应方之间的距离在预设范围内之后，在转至步骤706之前，还可包括响应方和发起方分别根据第一距离基准信和第二距离基准信息包括的身份识别信息对发起方和响应方的身份进行鉴权的步骤，只有在双方都鉴权成功时，才转至步骤706；否则，转至步骤701。
另外，在上述步骤705中，也可设置为只要通信双方中的任意一方的判断结果为是时，则可直接转至步骤706。
同样，在上述步骤706之后，发起方与响应方已经建立了射频通信连接，可通过建立的射频通信连接进行相应的数据交互。在该数据交互过程中，还可包括以下步骤：
发起方和响应方仍按照上述方式向对方分别发送第一距离基准信息和第二距离基准信息；
响应方和发起方仍按上述过程根据第一距离基准信息和第二距离基准信息判断发起方与其之间的距离是否在预设范围内；如双方的判断结果为是，则保持射频通信连接；否则，与发起方断开建立的射频通信连接。
当然，在上述建立射频通信连接之后，也可只选择一方向另一方发送距离基准信息实现相应的检测即可。
上述步骤中，各频点具体设置为500Hz、1KHz、1.5KHz、2KHz、2.5KHz、3KHz、4KHz、5KHz、10KHz、20KHz、30KHz或者10MHz等。
本发明的通信方法利用通信距离信息作为射频通信连接的必要条件，使得通信双方满足规定的通信距离条件即可即时、快速、高效的建立无线通信并进行数据交换，从而避免了预先配置、寻址、握手认证、配置复杂的交换协议等问题，为电子设备之间即时数据交换提供了极大便利，还可提高无线信道的利用率。同时，利用本发明的通信方法，各终端之间在限定的通信范围内，可进行自动组网，多台通信终端之间可两两相互通信，也可由一台终端作为发起终端，其它设备作为响应终端进行通信。可见，本发明的通信方法实现了通信双方之间的距离在预设范围内时的即时、快速、高效、自动组网的射频通信和数据交换。
以上所述仅为本发明的较佳实施例，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
