S530：零功耗网关根据反向散射信号产生对目标智能设备的控制信号。
S540：零功耗网关向目标智能设备发送控制信号，以控制目标智能设备的开关状态。
其中，反向散射信号用于产生对目标智能设备的控制信号，以控制目标智能设备的开关状态。
可选的，反向散射信号包括：目标智能设备的标识，以使零功耗网关获知该反向散射信号是用于目标智能设备对应的反向散射信号。
应理解的是，智能控制系统的最大特点是零功耗控制设备不主动发射信号，而是通过反射零功耗网关的检测信号，并对此信号进行调制，从而实现与零功耗网关的无线通信。
可选的，零功耗网关按一定周期t发射检测信号；零功耗控制设备接收到此信号，并从此信号中提炼出能量作为零功耗控制设备的能量源，即零功耗控制设备将检测信号作为载波，通过反向散射方式向零功耗网关发送反向散射信号。零功耗网关接收到此信号并进行解析，并产生对目标智能设备的控制信号，以控制目标智能设备的开关状态，如打开智能灯，打开智能窗帘，关闭智能空调等等。
综上，在本申请中引入了零功耗技术，来实现对智能设备的控制，从而可以降低控制成本、安装维护成本等。
可选的，反向散射信号可以存在以下三种情况，但不限于此：
情况一：反向散射信号仅包括目标智能设备的标识。
情况二：反向散射信号包括目标智能设备的标识和控制信息。其中，控制信息用于指示目标智能设备需要由打开状态切换为关闭状态，或者，由关闭状态切换为打开状态。
情况三：零功耗控制设备上安装有传感器；反向散射信号还包括：传感器的当前状态。
下面将针对三种情况，分别说明零功耗网关如何控制目标智能设备。
针对情况一，说明零功耗网关如何控制目标智能设备：
可实现方式一：零功耗网关根据反向散射信号的接收信号强度指示(Received Signal Strength Indication，RSSI)和历史反向散射信号的RSSI，产生对目标智能设备的控制信号。其中，历史反向散射信号是历史最近一次用于产生对目标智能设备的控制信号的反向散射信号。
可实现方式二：零功耗网关根据反向散射信号的相位和历史反向散射信号的相位，产生对目标智能设备的控制信号。其中，历史反向散射信号是历史最近一次用于产生对目标智能设备的控制信号的反向散射信号。
下面针对可实现方式一进行说明：
可选的，可实现方式一的应用场景可以是手势控制场景，例如：图6为本申请实施例提供的手势控制场景示意图，如图6所示，当手在零功耗控制设备与零功耗网关之间进行遮挡操作时，这时零功耗网关获取到的反向散射信号的RSSI相对于没有手势遮挡时获取到的反向散射信号的RSSI要弱。如上所述，零功耗网关按一定周期t发射检测信号，因此，假设在第i+1个周期零功耗网关获取到的反向散射信号的RSSI相对于第i个周期零功耗网关获取到的反向散射信号要弱，说明在第i+1个周期，手在零功耗控制设备与零功耗网关之间进行遮挡操作。这种情况，零功耗网关可以判定目标智能设备需要进行开关状态切换。其中，智能设备与零功耗网关可以按照按一定周期进行数据交换。数据交换包含智能设备的开关状态，零功耗网关可以将这些状态记录在本地内存内，例如如表2所示：
表2
智能设备 当前开关状态
智能设备1 打开状态
智能设备2 打开状态
智能设备3 关闭状态
…… ……
智能设备N 关闭状态
零功耗网关在判定目标智能设备需要进行开关状态切换时，可以在表2中查找目标智能设备的当前开关状态，例如：智能设备1的当前开关状态为打开状态，那么说明零功耗网关需要将智能设备1的开关状态从打开状态切换为关闭状态。再例如：智能设备3的当前开关状态为关闭状态，那么说明零功耗网关需要将智能设备3的开关状态从关闭状态切换为打开状态。
需要说明的是，为了防止对智能设备的误控制，在手势控制场景下，零功耗网关可以设置一个预设时长，该预设时长用于限制只有当零功耗网关获取到的当前的反向散射信号的RSSI相对于历史反向散射信号的RSSI变弱，并且当前的反向散射信号的RSSI持续时长达到该预设时长时，零功耗网关才确认当前手势操作是正常手持操作，即不是误操作或者误控制。进一步的，如果零功耗网关确认当前手势操作是正常手持操作，那么零功耗网关可以确定目标智能设备的当前状态。零功耗网关根据目标智能设备的当前状态进行状态切换。
示例性的，假设在第i+1个周期零功耗网关获取到的反向散射信号的RSSI相对于第i个周期零功耗网关获取到的反向散射信号要弱，说明在第i+1个周期，手在零功耗控制设备与零功耗网关之间进行遮挡操作。这种情况，零功耗网关需要判断当前获取到的反向散射信号的RSSI的持续时长，若该 时长达到预设时长，则零功耗网关判定目标智能设备需要进行开关状态切换。其中，智能设备与零功耗网关可以按照按一定周期进行数据交换。数据交换包含智能设备的开关状态，零功耗网关可以将这些状态记录在本地内存内，例如如表2所示，零功耗网关在判定目标智能设备需要进行开关状态切换时，可以在表2中查找目标智能设备的当前开关状态，例如：智能设备1的当前开关状态为打开状态，那么说明零功耗网关需要将智能设备1的开关状态从打开状态切换为关闭状态。再例如：智能设备3的当前开关状态为关闭状态，那么说明零功耗网关需要将智能设备3的开关状态从关闭状态切换为打开状态。
下面针对可实现方式二进行说明：
可选的，可实现方式二的应用场景可以是手势控制场景，其中，零功耗控制设备与零功耗网关之间可以存在多个通信信道，如CH1，CH2……CHN，每个通信信道的中心频率为f1，f2……fN，零功耗网关可以根据接收到的反向散射信号计算出各个通信信道的相位phase1，phase2……phaseN，其中，信号的相位信息与信号从发射端到接受端的路径有关。当接收端与发射端之间存在遮蔽物，则会因反射与折射改变信号路径，导致信号相位的变化。在此实施中，零功耗网关按一定周期t发射检测信号，并将控制设备的每一个通信信道与对应的相位信息记录在本地内存中。
例如：如图6所示，当手在零功耗控制设备与零功耗网关之间进行遮挡操作时，这时零功耗网关获取到的反向散射信号的相位相对于没有手势遮挡时获取到的反向散射信号的相位发生变化。如上所述，零功耗网关按一定周期t发射检测信号，因此，假设在第i+1个周期零功耗网关获取到的反向散射信号的相位相对于第i个周期零功耗网关获取到的反向散射信号发生变化，说明在第i+1个周期，手在零功耗控制设备与零功耗网关之间进行遮挡操作。这种情况，零功耗网关可以判定目标智能设备需要进行开关状态切换。其中，智能设备与零功耗网关可以按照按一定周期进行数据交换。数据交换包含智能设备的开关状态，零功耗网关可以将这些状态记录在本地内存内，例如如表2所示：零功耗网关在判定目标智能设备需要进行开关状态切换时，可以在表2中查找目标智能设备的当前开关状态，例如：智能设备1的当前开关状态为打开状态，那么说明零功耗网关需要将智能设备1的开关状态从打开状态切换为关闭状态。再例如：智能设备3的当前开关状态为关闭状态，那么说明零功耗网关需要将智能设备3的开关状态从关闭状态切换为打开状态。
需要说明的是，为了防止对智能设备的误控制，在手势控制场景下，零功耗网关可以设置一个预设时长，该预设时长用于限制只有当零功耗网关获取到的当前的反向散射信号的相位相对于历史反向散射信号的相位发送变化，并且当前的反向散射信号的相位持续时长达到该预设时长时，零功耗网关才确认当前手势操作是正常手持操作，即不是误操作或者误控制。进一步的，如果零功耗网关确认当前手势操作是正常手持操作，那么零功耗网关可以确定目标智能设备的当前状态。零功耗网关根据目标智能设备的当前状态进行状态切换。
示例性的，假设在第i+1个周期零功耗网关获取到的反向散射信号的相位相对于第i个周期零功耗网关获取到的反向散射信号发生变化，说明在第i+1个周期，手在零功耗控制设备与零功耗网关之间进行遮挡操作。这种情况，零功耗网关需要判断当前获取到的反向散射信号的相位的持续时长，若该时长达到预设时长，则零功耗网关判定目标智能设备需要进行开关状态切换。其中，智能设备与零功耗网关可以按照按一定周期进行数据交换。数据交换包含智能设备的开关状态，零功耗网关可以将这些状态记录在本地内存内，例如如表2所示，零功耗网关在判定目标智能设备需要进行开关状态切换时，可以在表2中查找目标智能设备的当前开关状态，例如：智能设备1的当前开关状态为打开状态，那么说明零功耗网关需要将智能设备1的开关状态从打开状态切换为关闭状态。再例如：智能设备3的当前开关状态为关闭状态，那么说明零功耗网关需要将智能设备3的开关状态从关闭状态切换为打开状态。
针对情况二，说明零功耗网关如何控制目标智能设备：
其中，如上所述，控制信息用于指示目标智能设备需要由打开状态切换为关闭状态，或者，由关闭状态切换为打开状态。因此，零功耗网关产生的控制信号可以直接包括：该控制信息和目标智能设备的标识。例如：零功耗网关向如表2所示的智能设备1发送控制信号，以控制智能设备1从打开状态切换为关闭状态。再例如：零功耗网关向如表2所示的智能设备3发送控制信号，以控制智能设备3从关闭状态切换为打开状态。
针对情况三，说明零功耗网关如何控制目标智能设备：
可选的，零功耗控制设备上安装有传感器。其中，反向散射信号包括该传感器的当前状态。例如：图7为本申请实施例提供的零功耗控制设备中微处理器与传感器的连接示意图，该传感器可以是一个开关设备，如图7所示，该传感器连接零功耗控制设备内微处理器的脚线Pn，Pm，触碰一次此传感器会造成Pn，Pm间的通路或断路，在第二次触碰前，Pn，Pm维持第一次触碰后的状态。在此实施 中，当零功耗控制设备接收到检测信号后，其内部微处理器获得能量，并检测Pn，Pm之间的状态。微处理器将传感器的当前状态携带在反向散射信号中。零功耗网关接收到反向散射信号之后，解码获得传感器的当前状态，并对当前状态和前一次状态进行比较，判断传感器的状态是否发生变化，如果发生了变化，则可以确定目标智能设备的当前状态。零功耗网关根据目标智能设备的当前状态进行状态切换。例如：零功耗网关获取到的传感器的当前状态为Pn，Pm间处于通路状态，而该当前状态为Pn，Pm间处于断路状态，基于此，零功耗网关可以确定目标智能设备的当前状态。零功耗网关根据目标智能设备的当前状态进行状态切换。
需要说明的是，关于零功耗网关如何确定目标智能设备的当前状态，以及如何进行状态切换可参考上文，本申请对此不再赘述。
需要说明的是，上述实施例中，零功耗网关是根据传感器的状态变化来控制目标智能设备，实际上，还可以根据传感器测得的速度变化等来控制目标智能设备，本申请对此不做限制。
综上，在本申请中，反向散射信号存在如上三种情况，基于此，零功耗网关可以在这三种情况下控制目标智能设备。

需要说明的是，本申请对S810和S820的先后顺序不做限制，对S830和S840的先后顺序也不做限制。
可选的，零功耗网关可以确定第一反向散射信号的RSSI和第二反向散射信号的RSSI；根据第一反向散射信号的RSSI和第二反向散射信号的RSSI，确定用户和目标智能设备的距离；根据用户和目标智能设备的距离产生对目标智能设备的控制信号。
可选的，任一个反向散射信号的RSSI，与，零功耗网关与发送反向散射信号的零功耗控制设备的距离R具有如下关系：RSSI＝1/R^4。
可选的，若用户和目标智能设备的距离小于预设距离，且目标智能设备的当前状态为关闭状态，则零功耗网关产生对目标智能设备的控制信号，以控制目标智能设备由关闭状态切换至打开状态；若用户和目标智能设备的距离大于或等于预设距离，且目标智能设备的当前状态为打开状态，则零功耗网关产生对目标智能设备的控制信号，以控制目标智能设备由打开状态切换至关闭状态。
应理解的是，该预设距离可以根据实际情况设置，例如：设置该预设距离为1米。
