具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
图1是根据一示例性实施例示出的一种定位的方法的流程图，如图1所示，该方法用于终端中，包括以下步骤。
在步骤S11中，采集并分析当前空间内无线设备的无线报文，得到该当前空间的第一 特征图谱。
本实施例中，可选的，当前空间为终端当前所在的空间，可以位于无线局域网内，且可以为该无线局域网中的任一个空间。该无线局域网可以为家庭的无线局域网，该无线局域网内通常具有多个空间，如卧室、客厅、书房、餐厅等等。可选的，无线局域网内还具有多个无线设备，可以分别布置在各个空间中，其中，无线设备可以固定布置在某个空间中，也可以是移动设备，可以在各个空间内随意移动。所述无线设备包括但不限于：路由器、智能手机、笔记本电脑、平板电脑等等。
在步骤S12中，将当前空间的第一特征图谱与预设的多个空间的特征图谱进行匹配。
可选的，可以预先生成多个空间的特征图谱，如无线局域网内所有空间的特征图谱。本实施例中，获取的每个空间的特征图谱都是不同的，具有唯一性。可选的，在特征图谱中也保存空间的信息，如空间的编号等，从而方便在特征图谱匹配后获取空间的信息。
本实施例中，所述终端可以为任一种具有接收无线报文和分析无线报文能力的终端，包括但不限于：嗅探器Sniffer、智能手机等等。其中，终端分析无线报文可以包括：在无线报文中提取发送该无线报文的无线设备的媒体访问控制(Media Access Control，简称：MAC)地址，以及获取接收的信号强度指示(Received Signal Strength Indication，简称：RSSI)等等，本实施例对此不做具体限定。所述无线报文可以为无线设备相互之间发送的无线报文，或者也可以为无线设备由于协议的要求周期性广播的无线报文。
其中，RSSI反映了无线设备的信号强度，当RSSI的值较高时，表明接收到该无线设备的信号越强，当RSSI的值较低时，表明接收到该无线设备的信号越弱。
在步骤S13中，在确定有与该当前空间的第一特征图谱相匹配的第二特征图谱时，获取该第二特征图谱对应的空间信息，得到空间定位结果。
其中，所述空间信息可以包括空间的标识信息，如空间编号，从而方便用户获知终端当前进入了无线局域网内的哪个空间，实现空间定位。
本实施例中，当空间定位成功后，可选的，还可以根据识别的空间触发相应的操作，如确定进入客厅，则自动开启音箱；或者，如确定进入书房，则自动开启ZigBee灯泡等等，此处不做过多说明。所述触发相应的操作可以由终端实现，即终端除了具有接收和分析无线报文的能力，还具有触发相应操作的能力；或者也可以由其他智能设备在收到终端的通知后实现，即终端具有接收和分析无线报文的能力，且能够提示当前进入的是哪个空间，而其它智能设备根据终端的提示则可以触发相应的操作，本实施例对此不做具体限定。
本实施例中，可选的，任一个特征图谱可以包括无线设备的标识与信号质量的对应关系。可选的，无线设备的标识可以为MAC地址，无线设备的信号质量可以为RSSI。其中，特征图谱内的无线设备是指终端在该空间内可以接收到的信号所对应的无线设备，该无线设备可以位于该空间内，也可以位于其它空间内。例如，一个空间的特征图谱包括3个无线设备的标识与信号质量的对应关系，该3个无线设备中有两个位于该空间内，另一个则位于相邻的空间内。
本实施例中，可选的，将当前空间的第一特征图谱与预设的多个空间的特征图谱进行匹配，包括：
对该多个空间中每一个空间的特征图谱，将该空间的特征图谱与该第一特征图谱进行比较，如果该空间的特征图谱中包括该当前空间内每一个无线设备的标识，且该第一特征图谱中无线设备的信号质量与该空间的特征图谱中无线设备的信号质量相似，则确定该空间的特征图谱与该第一特征图谱相匹配。
本实施例中，可选的，第一特征图谱中无线设备的信号质量与该空间的特征图谱中无线设备的信号质量相似，包括：
该第一特征图谱中有N个无线设备的信号质量落入该空间的特征图谱中对应无线设备的信号质量范围内，且该N达到指定个数。
本实施例中，可选的，上述方法还可以包括：
在该多个空间中的每一个空间内，采集能够接收到的每一个无线设备的无线报文，分析该无线报文，得到该每一个无线设备的媒体访问控制MAC地址，与接收该无线设备的无线报文的接收的信号强度指示RSSI，建立该每一个无线设备的MAC地址和该无线设备的RSSI的对应关系，得到该空间的特征图谱。
本实施例中，可选的，采集能够接收到的每一个无线设备的无线报文为多次采集，且将该每一个无线设备多次采集得到的RSSI组成一个该无线设备的RSSI范围。
本实施例提供的上述方法，通过采集并分析当前空间内无线设备的无线报文，得到所述当前空间的第一特征图谱，将所述当前空间的第一特征图谱与预设的多个空间的特征图谱进行匹配，在确定有与所述当前空间的第一特征图谱相匹配的第二特征图谱时，获取所述第二特征图谱对应的空间信息，得到当前空间的定位结果，实现了空间的自动定位，为自动识别当前进入哪一个空间提供了有效的解决方案。
图2是根据另一示例性实施例示出的一种定位的方法的流程图，如图2所示，该方法用于终端中，包括以下步骤。
在步骤S21中，采集并分析当前空间内无线设备的无线报文，得到该当前空间的第一特征图谱。
其中，当前空间为终端当前所在的空间，可以位于无线局域网中。该无线局域网内可以具有多个空间。所述多个空间中每一个空间具有一个特征图谱，该特征图谱可以包括无线设备的标识与信号质量的对应关系。所述多个空间中的每一个空间内可以布置一个或多个无线设备，此处不限定。例如，在用户家庭内，客厅中布置有路由器、电视、Wi-Fi摄像头；卧室中布置有Wi-Fi空调、蓝牙音箱、Zigbee灯泡等等。其中，客厅与卧室相邻，在客厅中也能够接收到卧室的无线设备发出的信号，因此，客厅的特征图谱中不仅包括路由器的标识与信号质量的对应关系、电视的标识与信号质量的对应关系、Wi-Fi摄像头的标识与信号质量的对应关系，还可以包括Wi-Fi空调的标识与信号质量的对应关系、蓝牙 音箱的标识与信号质量的对应关系、Zigbee灯泡的标识与信号质量的对应关系，只是该特征图谱中卧室无线设备的信号质量比客厅无线设备的信号质量弱一些。
可选的，当前空间的第一特征图谱可以包括无线设备的标识与信号质量的对应关系。
在步骤S22中，对该多个空间中每一个空间的特征图谱，将该空间的特征图谱与该第一特征图谱进行比较，如果该空间的特征图谱中包括该当前空间内每一个无线设备的标识，且该第一特征图谱中无线设备的信号质量与该空间的特征图谱中无线设备的信号质量相似，则确定该空间的特征图谱与该第一特征图谱相匹配。
其中，该空间的特征图谱中无线设备的个数可以大于或等于第一特征图谱中无线设备的个数。例如，该空间的特征图谱中包括五个无线设备，分别对应无线设备1～5，当前空间的第一特征图谱包括四个无线设备，分别对应无线设备1～4，其中，无线设备5的信号可能由于过弱，因此，没有被终端接收到。
本实施例中，可选的，第一特征图谱中无线设备的信号质量与该空间的特征图谱中无线设备的信号质量相似，包括：
第一特征图谱中有N个无线设备的信号质量落入该空间的特征图谱中对应无线设备的信号质量范围内，且该N达到指定个数。
其中，所述指定个数可以根据需要预先设置，如2个、3个或者5个等等，本实施例对此不做具体限定。
本实施例中，可选的，多个空间的特征图谱中每一个空间的特征图谱都包括一个信号质量的范围，且对应一个无线设备的标识。N最少为一个，最多为该当前空间的第一特征图谱中所有无线设备的总数。如果当前空间的第一特征图谱中所有无线设备的信号质量均落入该空间的特征图谱中对应无线设备的信号质量范围内，则定位的结果更精确。
例如，该空间的特征图谱包括3个无线设备的标识和对应的信号质量范围，当前空间的第一特征图谱包括3个无线设备的标识和对应的信号质量。其中，当前空间的第一特征图谱中3个无线设备的标识与所述空间的特征图谱中的3个无线设备的标识相同。如果指定个数为3，则在当前空间的第一特征图谱中3个无线设备的信号质量都分别落入该空间的特征图谱中对应无线设备的信号质量范围内时，确定该空间的特征图谱与当前空间的第一特征图谱匹配。如果指定个数为2，则当前空间的第一特征图谱中有2个无线设备的信号质量分别落入该空间的特征图谱中对应无线设备的信号质量范围内时，就可以确定该空间的特征图谱与当前空间的第一特征图谱匹配。
在步骤S23中，在确定有与该当前空间的第一特征图谱相匹配的第二特征图谱时，获取该第二特征图谱对应的空间信息，得到空间定位结果。
本实施例中，可选的，上述方法还可以包括：
在该多个空间中的每一个空间内，采集能够接收到的每一个无线设备的无线报文，分析该无线报文，得到该每一个无线设备的媒体访问控制MAC地址，与接收该无线设备的无线报文的接收的信号强度指示RSSI，建立该每一个无线设备的MAC地址和该无线设备 的RSSI的对应关系，得到该空间的特征图谱。
其中，可选的，采集能够接收到的每一个无线设备的无线报文为多次采集，且将该每一个无线设备多次采集得到的RSSI组成一个该无线设备的RSSI范围。
本实施例提供的上述方法，通过采集并分析当前空间内无线设备的无线报文，得到当前空间的第一特征图谱，对该多个空间中每一个空间的特征图谱，将该空间的特征图谱与该第一特征图谱进行比较，如果该空间的特征图谱中包括该当前空间内每一个无线设备的标识，且该第一特征图谱中无线设备的信号质量与该空间的特征图谱中无线设备的信号质量相似，则确定该空间的特征图谱与该第一特征图谱相匹配，在确定有与当前空间的第一特征图谱相匹配的第二特征图谱时，获取第二特征图谱对应的空间信息，得到当前空间的定位结果，实现了空间的自动定位，为自动识别当前进入哪一个空间提供了有效的解决方案。
图3是根据另一示例性实施例示出的一种定位的方法的流程图，如图3所示，该方法用于终端中，包括以下步骤。
在步骤S31中，在多个空间中的每一个空间内，采集能够接收到的每一个无线设备的无线报文，分析该无线报文，得到该每一个无线设备的媒体访问控制MAC地址，与接收该无线设备的无线报文的接收的信号强度指示RSSI，建立该每一个无线设备的MAC地址和该无线设备的RSSI的对应关系，得到该空间的特征图谱。
其中，上述多个空间可以为无线局域网内的多个空间。
其中，可选的，采集能够接收到的每一个无线设备的无线报文为多次采集，且将该每一个无线设备多次采集得到的RSSI组成一个该无线设备的RSSI范围。
例如，两次采集得到一个无线设备的RSSI分别为-60dbm和-70dbm，则可以得到一个信号质量范围为[-70dbm，-60dbm]。
可选的，当采集到多个信号质量时，可以选取其中的最大值和最小值组成一个信号质量范围，本实施例对此不做具体限定。
在步骤S32中，采集并分析当前空间内无线设备的无线报文，得到该当前空间的第一特征图谱。
其中，该第一特征图谱可以包括无线设备的MAC地址和该无线设备的RSSI的对应关系。可选的，该第一特征图谱中可以包括一个或多个无线设备，该无线设备可以是当前空间内的无线设备，也可以是其它空间内的无线设备。

其中，可选的，该第一特征图谱中无线设备的信号质量与该空间的特征图谱中无线设 备的信号质量相似，包括：
该第一特征图谱中有N个无线设备的信号质量落入该空间的特征图谱中对应无线设备的信号质量范围内，且该N达到指定个数。该指定个数可以根据需要设置，此处不限定。
