下面结合附图对本发明作进一步详细描述。
根据本发明的一个方面，提供了一种物联网基于连接数量的路由器切换方法。其中，该方法应用在如图1所示的物联网络中，如图1所示，该物联网络包括：物联网终端10、物联网路由器20以及无线接入控制器30，上述物联网终端根据不同的情况可以具有不同的表现形式，例如该物联网终端具体可以为：手机、平板电脑、计算机等设备，当然其也可以包含带有联网功能的其他设备，例如智能电视、智能空调、智能水壶或一些物联网的智能设备，上述物联网终端10通过无线方式与物联网路由器20连接，物联网路由器20通过另一种方式(即与无线方式不同的连接方式)接入互联网，上述无线方式包括但不限于：蓝牙、WIFI等方式，上述另一种方式可以为，LTE或有线方式，通常大部分的情况路由器与网关之间通过有线连接。图1中以有线方式为示例，为了方便表示，这里仅以一根实线表示。
上述无线接入控制器30根据物联网的大小可以是一台个人电脑(英文：Personal computer，PC)，当然在实际应用中，也可以是多台PC、服务器或核心网侧设备，本发明具体实施方式并不局限上述无线接入控制器的具体表现形式。
参阅图2，图2为本发明提供的一种物联网基于连接数量的路由器切换方 法，该方法如图2所示，包括如下步骤：
步骤S201、物联网路由器接收物联网终端发送的数据包；
上述步骤S201中接收物联网终端发送的数据包仅限通过无线连接的方式发送数据包，该无线方式包括但不限于：蓝牙、无线保真(英文：Wireless Fidelity,WIFI)或Zigbee等无线方式，其中，上述WIFI需要遵守IEEE802.11b的标准。
需要说明的是，这里的物联网以及物联网路由器仅仅只是针对无线路由器，因为对于物联网来说，其接入的设备数量众多，对于路由器来说，如果通过有线连接，首先路由器的接入数量会有所限制，并且对于家庭来说，均用有线连接，对于家庭用户的布线来说是无法想象的，另外此有线的成本也非常高，所以本发明的技术方案中的中物联网终端与路由器之间的连接仅限无线连接。
上述物联网终端依据不同的场景，可以有不同的表现形式，例如，在家电物联网中，上述物联网终端具体可以为：智能电视、智能空调、智能冰箱等具有通信功能的终端设备，在智能小区中，上述物联网终端具体可以为：智能电灯、智能门、智能门窗控制器、智能窗帘等设备，本发明具体实施方式并不局限上述物联网终端的具体表现形式。
步骤S202、物联网路由器统计已经连接的终端数量，该已经连接的物联网终端为在设定时间内向所述物联网路由器发送数据包或接收物联网路由器发送数据包的终端；
上述步骤S202中的设定时间可以由用户自行设定，当然在实际应用中，也可以由厂家通过默认设置的方式来实现。
上述步骤S202中的统计可以为周期性的统计，上述周期可以由用户自行设定，例如在本发明一个具体的实施方案中，可以在物联网路由器上设置一个外部设置接口，由外部设备连接该物联网路由器来设定上述周期，当然为了方便用户使用，上述周期也可以由厂家来设定，本发明并不局限上述周期的具体值。
步骤S203、判断该已经连接的物联网终端数量是否低于数量阈值，如已经连接的物联网终端数量高于数量阈值，则将物联网终端切换到备用物联网路由器。
上述步骤S203将物联网终端切换到备用物联网路由器的方法可以参见另一实施例的描述，这里不在赘述。
上述将物联网终端切换到备用物联网路由器的具体方法可以为：
物联网路由器接收每个备用物联网路由器的广播消息，该广播消息内包含已连接的物联网终端的数量，物联网路由器提取该广播消息中的已连接的物联网终端的数量，建立备用物联网路由器与已连接的物联网终端的数量的列表，物联网路由器从该列表中提取已连接的终端的数量低于数量阈值的物联网路由器作为物联网终端切换的备用物联网路由器。
上述将物联网终端切换到备用物联网路由器的具体方法还可以为：
物联网路由器统计每个备用物联网路由器的已连接的物联网终端的数量的变化趋势，如该变化趋势为递减，则将该备用物联网路由器的切换优先级调高，物联网终端选择切换优先级最高的物联网路由器作为切换的备用物联网路由器。
设置此方案的目的主要是为了避免接入点切换过于频繁，因为对于主物联网路由器来说，其终端接入数量多，但是对于物联网路由器来说，其终端接入数量是变化的，所以需要获取该终端接入数量在设定时间段的变化趋势，首先，不能是递增的，如果是递增，那么对于很有可能切换到该路由器后该终端数量很快会再次高于数量阈值，这样就会再次切换，甚至是出现空切换，所以需要查找递减的变化趋势的物联网路由器。
可选的，上述方法在步骤S203之后还可以包括：
物联网路由器接收另外物联网路由器发送的切换请求，所述切换请求包括：第二物联网终端的标识以及第二物联网终端发送数据包对应的帧序列号(第二物联网终端对应的帧序列号)；
物联网路由器存储所述帧序列号，向所述第二物联网终端发送连接请求，所述连接请求的目的地址为所述第二物联网终端的标识；
物联网路由器接收第二物联网终端发送的连接响应，物联网路由器建立与所述第二物联网终端的连接，向所述另外(即第三)物联网路由器发送切换响应，该切换响应包括：第二物联网终端切换成功的指示。
上述指示可以为一个bit位的值表示，当然也可以是其他的形式表示。
本发明提供的技术方案通过周期性的检测物联网终端的接入终端数量，对该接入终端数量进行判断，当低于数量阈值时，将该物联网终端切换到备用物联网路由器进行通信，从而保证了数据传输的速率，提高了技术的有效性。
根据本发明的另一个方面，提供了一种物联网基于连接数量的路由器切换方法。其中，该方法应用在如图3所示的物联网络中，如图3所示，该物联网络包括：物联网终端39、多个物联网路由器(，为了描述的方便，这里将多个物联网路由器标识为21、22)和无线接入控制器30。上述物联网终端根据不同的情况可以具有不同的表现形式，例如该物联网终端具体可以为：手机、平板电脑、计算机等设备，当然其也可以包含带有联网功能的其他设备，例如智能电视、智能空调、智能水壶或一些物联网的智能设备，上述物联网终端39通过无线方式与路由器21连接，其中路由器22为路由器21的备用物联网路由器，路由器21通过另一种方式(即与无线方式不同的连接方式)接入互联网，参阅图3，这里的正在进行无线通信连接通过实线表示，即将要进行无线通信连接通过虚线连接，上述无线方式包括但不限于：蓝牙、WIFI等方式，上述另一种方式可以为，LTE或有线方式。图3中以有线方式为示例，为了方便表示，这里仅以一根实线表示。
上述无线接入控制器30根据物联网的大小可以是一台个人电脑(英文：Personal computer，PC)，当然在实际应用中，也可以是多台PC或服务器，本发明具体实施方式并不局限上述无线接入控制器的具体表现形式。
参阅图4，图4为本发明提供的一种物联网基于连接数量的路由器切换方法，该方法如图4所示，包括如下步骤：
步骤S401、物联网路由器接收物联网终端发送的数据包；
上述步骤S401中接收物联网终端发送的数据包仅限通过无线连接的方式发送数据包，该无线方式包括但不限于：蓝牙、无线保真(英文：Wireless Fidelity,WIFI)或Zigbee等无线方式。
需要说明的是，这里的物联网以及路由器仅仅只是针对无线路由器，因为对于物联网来说，其接入的设备数量众多，对于路由器来说，如果通过有线连接，首先路由器的接入数量会有所限制，并且对于家庭来说，均用有线连接，对于家庭用户的布线来说是无法想象的，另外此有线的成本也非常高，所以本 发明的技术方案中的中物联网终端与路由器之间的连接仅限无线连接。
上述物联网终端依据不同的场景，可以有不同的表现形式，例如，在家电物联网中，上述物联网终端具体可以为：智能电视、智能空调、智能冰箱等具有通信功能的终端设备，在智能小区中，上述物联网终端具体可以为：智能电灯、智能门、智能门窗控制器、智能窗帘等设备，本发明具体实施方式并不局限上述物联网终端的具体表现形式。
步骤S402、物联网路由器统计已经连接的物联网终端数量；
上述步骤S402中的统计的周期可以由用户自行设定，例如在本发明一个具体的实施方案中，可以在物联网路由器上设置一个外部设置接口，由外部设备连接该物联网路由器来设定上述周期，当然为了方便用户使用，上述周期也可以由厂家来设定，本发明并不局限上述周期的具体值。
步骤S403、判断该连接的终端数量是否低于数量阈值，如连接的终端的数量高于数量阈值，则向备用物联网路由器22发送切换请求，该切换请求包括但不限于：物联网终端的标识和帧序列号；
上述步骤S403中的帧可以为：多个媒体接入控制协议数据单元(英文：medium access control protocol data unit，MPDU)，上述帧序列号可以为标识该帧发送顺序的编号。物联网终端的标识具体可以为：物联网终端的MAC地址，当然在实际应用中也可以采用其他方式来标识该物联网终端，例如通过IP地址或其他的标识来标识该物联网终端。
步骤S404、物联网路由器接收备用物联网路由器发送的切换响应，该切换响应可以包括该物联网终端是否切换成功的指示，该指示值具体可以为，切换成功或切换不成功，其具体可以在切换响应的包头字段中用一个bit来表示，例如，以1表示切换成功，以0表示切换不成功，当然也可以为以0表示切换成功，以1表示切换不成功。本发明并不限制上述表示的具体形式。
步骤S405、物联网路由器删除该物联网终端的信息，该物联网终端的信息包括但不限于：帧序列号。
对此删除是为了放置该物联网终端从备用物联网路由器22切换回物联网路由器21时出现帧序列号混乱的问题。
本发明提供的方法在进行切换时，将帧序列号携带在切换请求中发送给备 用物联网路由器，这样使得备用物联网路由器中帧序列号与物联网终端的帧序列号完全一致，因为对于切换来说，其需要持续一段时间，如不向该帧序列号发送给备用物联网路由器，那么由于帧序列号的不同，很可能导致丢包的现象出现，这里避免了丢包的情况出现，所以其具有减少包的丢失率的优点。
需要说明的是，上述备用物联网路由器接收到该切换请求以后，可以进行如图5所示的操作步骤，该步骤如图5所示，包括：
步骤S501、备用物联网路由器存储该帧序列号，并向该物联网终端发送连接请求，该连接请求的目的标识可以为该物联网终端的标识。
步骤S502、备用物联网路由器接收物联网终端发送的连接响应；
步骤S503、备用物联网路由器与物联网终端建立无线连接，向物联网路由器发送切换响应。
根据本发明的又一个方面，提供了一种物联网基于连接数量的路由器切换方法。其中，该方法应用在如图3所示的物联网络中，如图3所示，该物联网络包括：物联网终端39、多个物联网路由器(，为了描述的方便，这里将多个物联网路由器标识为21、22)和无线接入控制器30。上述物联网终端根据不同的情况可以具有不同的表现形式，例如该物联网终端具体可以为：手机、平板电脑、计算机等设备，当然其也可以包含带有联网功能的其他设备，例如智能电视、智能空调、智能水壶或一些物联网的智能设备，上述物联网终端39通过无线方式与路由器21连接，其中路由器22为路由器21的被备用物联网路由器，路由器21通过另一种方式(即与无线方式不同的连接方式)接入互联网，参阅图3，这里的正在进行无线通信连接通过实线表示，即将要进行无线通信连接通过虚线连接，上述无线方式包括但不限于：蓝牙、WIFI等方式，上述另一种方式可以为，LTE或有线方式。图3中以有线方式为示例，为了方便表示，这里仅以一根实线表示。
上述无线接入控制器30根据物联网的大小可以是一台个人电脑(英文：Personal computer，PC)，当然在实际应用中，也可以是多台PC或服务器，本发明具体实施方式并不局限上述无线接入控制器的具体表现形式。
参阅图6，图6为本发明提供的一种物联网基于连接数量的路由器切换方法，该方法如图6所示，包括如下步骤：
步骤S601、物联网路由器接收物联网终端发送的数据包；
上述步骤S601中接收物联网终端发送的数据包仅限通过无线连接的方式发送数据包，该无线方式包括但不限于：蓝牙、无线保真(英文：Wireless Fidelity,WIFI)或Zigbee等无线方式，其中，上述WIFI需要遵守IEEE802.11b的标准。
需要说明的是，这里的物联网以及AP仅仅只是针对无线AP，因为对于物联网来说，其接入的设备数量众多，对于AP来说，如果通过有线连接，首先AP的接入数量会有所限制，并且对于家庭来说，均用有线连接，对于家庭用户的布线来说是无法想象的，另外此有线的成本也非常高，所以本发明的技术方案中的中物联网终端与AP之间的连接仅限无线连接。
上述物联网终端依据不同的场景，可以有不同的表现形式，例如，在家电物联网中，上述物联网终端具体可以为：智能电视、智能空调、智能冰箱等具有通信功能的终端设备，在智能小区中，上述物联网终端具体可以为：智能电灯、智能门、智能门窗控制器、智能窗帘等设备，本发明具体实施方式并不局限上述物联网终端的具体表现形式。
步骤S602、物联网路由器统计已经连接的终端数量；
上述步骤S602中的统计的周期可以由用户自行设定，例如在本发明一个具体的实施方案中，可以在物联网路由器上设置一个外部设置接口，由外部设备连接该物联网路由器来设定上述周期，当然为了方便用户使用，上述周期也可以由厂家来设定，本发明并不局限上述周期的具体值。
步骤S603、物联网路由器接收每个备用物联网路由器发送的接入终端数量；
上述步骤S603的实现方案具体可以为，通过有线方式来接收每个备用物联网路由器发送的接入终端数量，其具体的实现的方案可以采用心跳消息中携带接入终端数量，因为对于每个物联网路由器来说，其接入终端数量均是实时变化的，那么如何得到最新的接入终端数量就是一个问题，这里采用心跳消息携带接入终端数量，有两个优点，第一，可以通过心跳消息来检测该备用物联网路由器是否正常(如能够接收到该心跳消息，即确定该正常，否则，确定其故障)，第二心跳消息本来就是周期的发送，方便物联网路由器实时获取每个 备用物联网路由器发送的接入终端数量。
步骤S604、物联网路由器判断该接入终端数量是否低于数量阈值，如该物联网终端的接入终端数量低于数量阈值，将物联网终端切换到接入终端数量最低的备用物联网路由器。
上述步骤S604选择接入终端数量最低的备用物联网路由器能够有效的分配终端，避免物联网路由器的终端数量过高，超过路由器的负荷，导致备用物联网路由器的负荷过重。
本发明提供的技术方案通过周期性的检测物联网终端的接入终端数量，对该接入终端数量进行判断，当低于数量阈值时，将该物联网终端切换到备用物联网路由器进行通信，从而保证了数据传输的速率，提高了技术的有效性。
