Description

功率调节装置及方法
【技术领域】
本申请涉及通信网络领域，特别是涉及一种功率调节装置及方法。
【背景技术】
随着无线网络通信技术的发展，无线保真（Wireless Fidelity，WiFi）技术的应用越来越广泛，越来越多的终端设备通过WiFi接入点（Access Point，AP）接入到核心网。由于终端设备接收到WiFi接入点发出的信号的质量受到终端设备到WiFi接入点的距离和环境干扰等因素影响，为了保证终端设备始终能够良好地接收到WiFi接入点发出的信号并且减少能耗，需要对WiFi接入点的发射功率进行调节，例如，终端设备离WiFi接入点的距离比较近时，降低WiFi接入点的发射功率以减少能耗；终端设备离WiFi接入点的距离比较远时，提高WiFi接入点的发射功率，以保证接收质量。
现有技术提供了一种功率调节方法，每隔一个预设时间获取当前WiFi接入点的接收信号强度指示（Received Signal Strength Indication，RSSI）值，并根据所获取的RSSI值动态调整WiFi接入点的发射功率。一般而言，终端设备距离WiFi接入点的距离比较近时，RSSI值较大，终端设备距离WiFi接入点的距离比较远时，RSSI值较小。所以，根据RSSI值调节发射功率能够使得终端设备良好地接收到WiFi接入点发出的信号并且减少能耗。
但是，RSSI值只能反映WiFi接入点接收到终端设备所发出信号的强度，并不能真实地反映终端设备接收到WiFi接入点所发出的信号的状况。在一些情况下，WiFi接入点的接收信号强度很大，但是终端设备接收到WiFi接入点所发出的信号的质量却很差，例如，WiFi接入点与终端设备的距离很近，但是环境中的噪音却很大时，终端设备接收到信号的强度同样很大，但是因为噪音也很大，终端设备在解码时会受到噪音的影响，不能很好地将信号还原出来，造成终端设备的接收信号质量很差。
在这种情况下，本来应该继续提高发射功率进而提高终端设备的接收信号质量。但是，在现有机制下，WiFi接入点会根据RSSI值较大从而做出不需要提高发射功率的错误判断，导致终端设备的接收信号质量很差。

【具体实施方式】
以下描述中，为了说明而不是为了限定，提出了诸如特定系统结构、接口、技术之类的具体细节，以便透彻理解本申请。然而，本领域的技术人员应当清楚，在没有这些具体细节的其它实施方式中也可以实现本申请。在其它情况中，省略对众所周知的装置、电路以及方法的详细说明，以免不必要的细节妨碍本申请的描述。
参阅图1，图1是本申请功率调节方法一实施方式的流程图。本实施方式从功率调节装置的角度出发进行描述，其中，功率调节装置可以是网关或者路由器。本实施方式包括如下步骤：
S101：接收终端设备发送的信号。
功率调节装置启动后，使用默认的预设发射功率进行工作。当终端设备需要接入功率调节装置时，向功率调节装置发送信号以请求接入该功率调节装置；或者，当终端已经接入功率调节装置后，终端可与功率调节装置进行信号交互。功率调节装置接收终端设备发送的信号。
具体地，在本发明实施例中，功率调节装置接收终端设备发送的信号。应当理解，该信号是终端设备发送的消息的传递形式，其是传递消息的载体，例如在本实施例中，该信号可以为电信号。进一步理解，终端设备发送的信号的本质是消息，消息为信号要传递的内容，其为信号的本质。即，在本发明实施例中，信号与消息是载体与内容、形式与本质的关系；换言之，功率调节装置接收终端设备发送的信号，包括功率调节装置接收终端设备发送的消息，后者为前者的一种具体实现方式，也是更为本质的一种实现方式。其中，在功率调节装置接收终端设备发送的消息时，该消息可以为控制帧、管理帧、数据帧。其中，
控制帧包括：确认字符（Acknowledgement,ACK）帧、请求发送（Request to Send，RTS）帧、取消发送（Clear to Send,CTS）帧、省电轮询（Power Save-Poll，PS-Poll）帧等。管理帧包括：探测请求（Probe Request）帧、信标（Beacon）帧、身份验证（Authentication）帧、解除身份验证（Deauthentication）帧等。当功率调节装置与终端设备建立连接的过程中，接收终端设备发送的管理帧、控制帧；当功率调节装置与终端设备建立连接后进行数据传输时，接收终端设备发送的数据帧。
S102：根据所述信号获取信号质量指标，其中，所述信号质量指标用于标识所述终端接收到所述功率调节装置发送的信号的信号质量。
当功率调节装置接收到终端设备发送的信号后，根据接收到的信号获取终端设备的接收信号的信号质量指标。其中，信号质量指标用于标识终端接收到该功率调节装置发送的信号的信号质量，即，信号质量指标用于标识终端设备的接收信号的信号质量。信号质量指标可以包括信号质量值或噪声质量值，信号质量值用于标识终端设备接收到功率调节装置发送的信号的质量，信号质量值可以包括信道质量值以及信号强度值；噪声质量值用于标识终端设备接收到的信号的噪声，噪声质量值可以包括噪声信号的信号强度值。在本实施方式中，通过信号质量指标衡量终端设备的接收信号的信号质量。当信号质量指标为信号质量值时，信号质量指标的值越高表示终端设备的接收信号的信号质量越好；当信号质量指标为噪声质量值时，信号质量指标的值越高表示终端设备接收的信号中噪声信号的信号强度越强，信号质量越差。
例如，当信号质量指标为信号质量值时，如果信号质量指标为100，则表示终端设备的接收信号的信号质量为预设的理想参考值；如果信号质量指标为90，则表示终端设备的接收信号的信号质量为预设的理想参考值的90%。
当信号质量指标为噪声质量值时，如果信号质量指标为100，则表示接收到的信号都是噪声信号，接收信号的信号质量为0；如果信号质量指标为90，则表示接收的信号中噪声信号为90%，信号质量为预设的理想参考值的10%。
S103：根据所述信号质量指标调节发射功率。
功率调节装置获取到信号质量指标后，将信号质量指标与预设阈值进行比较，并根据比较结果调节发射功率，将调节后的发射功率作为最终的发射功率。
当信号质量指标为信号质量值时，如果信号质量指标小于预设阈值时，则在原发射功率的基础上增加发射功率；如果信号质量指标大于或等于预设阈值时，则不调节发射功率。例如，当信号质量指标为信号质量值，预设阈值为90时，如果获取到的信号质量指标为95，则功率调节装置判断当前的信号质量指标大于预设阈值，不调节发射功率，即保持默认的预设发射功率；如果获取到的信号质量指标为60，则功率调节装置判断当前的信号质量指标小于预设阈值，在默认的预设发射功率的基础上增加发射功率；如果获取到的信号质量指标为90，则功率调节装置判断当前的信号质量指标等于预设阈值，将当前的发射功率调至默认的预设发射功率。
当信号质量指标为噪声质量值时，如果信号质量指标小于或预设阈值时，则不调节发射功率；如果信号质量指标大于预设阈值时，则在原发射功率的基础上增加发射功率。例如，当信号质量指标为噪声质量值，预设阈值为10时，如果获取到的噪声质量值为5，则功率调节装置判断当前的信号质量指标小于预设阈值，不调节发射功率，即保持默认的预设发射功率；如果获取到的信号质量指标为20，则功率调节装置判断当前的信号质量指标大于预设阈值，在默认的预设发射功率的基础上增加发射功率；如果获取到的信号质量指标为5，则功率调节装置判断当前的信号质量指标等于预设阈值，将当前的发射功率调至默认的预设发射功率。
功率调节装置将调节后的发射功率作为最终的发射功率。
可以理解的是，增加后的发射功率不超过功率调节装置正常工作所允许的最大值，默认的预设发射功率、预设阈值、增加的发射功率值可根据实际需求设置，此处不作限定。
可以理解的是，在本实施方式中，只设置了一个预设阈值，在其他实施方式中，也可以设置至少两个预设阈值，至少两个阈值构成至少三个区间，每个区间对应一个需要增加或减小的发射功率值，根据信号质量指标所属的区间调节发射功率。
S104：按所述调节后的发射功率发送信号。
功率调节装置按照调节后的发射功率发送信号，与网络中的终端设备进行通信。
上述方案中，通过根据终端设备发送的信号获取信号质量指标，并根据信号质量指标调节发射功率，实现了功率调节装置根据终端设备的接收信号的信号质量指标动态调整发射功率，即使当功率调节装置发送的信号受到环境干扰、以及信号强度受到墙壁等障碍物的阻隔而衰减时，也能保证终端设备的接收性能，进而增强通信的可靠性。
请参阅图2，图2是本申请功率调节方法的另一实施方式的流程图。本实施方式从功率调节装置的角度出发进行描述，其中，功率调节装置可以是网关或者路由器。本实施方式包括如下步骤：
本实施方式与上一实施方式类似，其不同之处在于步骤S203~S204，步骤S201~S202请参阅步骤S101~S102及相关描述，此处不再赘述。
S203：每隔第一预设时间统计所述信号质量指标的最小值，并每隔第二预设时间计算所述最小值的平均值。
功率调节装置每隔第一预设时间统计信号质量指标的最小值，并每隔第二预设时间计算最小值的平均值，其中，每隔第二预设时间对应一个最小值的平均值，并且可按时间先后顺序顺次排列，排在后的平均值为当前的平均值。
例如，每隔5秒钟统计一次终端设备的接收信号的信号质量指标的最小值，并每隔1分钟计算出在这一分钟内12个最小值的平均值。在本实施方式中，第一预设时间为5秒钟，第二预设时间为1分钟，可以理解的是，在其他实施方式中也可以设置为其他的时间值。
S204：根据所述最小值的平均值调节发射功率。
当功率调节装置得到当前最小值的平均值后，将最小值的平均值与预设阈值进行比较，并根据比较结果调节发射功率，将调节后的发射功率作为最终的发射功率。
当信号质量指标为信号质量值时，如果功率调节装置判断最小值的平均值小于预设阈值，则在原发射功率的基础上增加发射功率；如果功率调节装置判断最小值的平均值大于或等于预设阈值，则不调节发射功率。当信号质量指标为噪声质量值时，如果功率调节装置判断最小值的平均值小于或等于预设阈值，则不调节发射功率；如果功率调节装置判断最小值的平均值大于预设阈值，则在原发射功率的基础上增加发射功率。
例如，当信号质量指标为信号质量值，预设阈值为90时，如果获取到的最小值的平均值为95，则功率调节装置判断当前的最小值的平均值大于预设阈值，不调节发射功率，即保持默认的预设发射功率；如果获取到的最小值的平均值60，则功率调节装置判断当前的最小值的平均值小于预设阈值，在默认的预设发射功率的基础上增加发射功率；如果获取到的最小值的平均值为90，则功率调节装置判断当前的最小值的平均值等于预设阈值，将当前的发射功率调至默认的预设发射功率。
当信号质量指标为噪声质量值，预设阈值为10时，如果获取到的最小值的平均值为5，则功率调节装置判断当前的最小值的平均值小于预设阈值，不调节发射功率，即保持默认的预设发射功率；如果获取到的最小值的平均值为20，则功率调节装置判断当前的最小值的平均值大于预设阈值，在默认的预设发射功率的基础上增加发射功率；如果获取到的最小值的平均值为5，则功率调节装置判断当前的最小值的平均值等于预设阈值，将当前的发射功率调至默认的预设发射功率。
功率调节装置将调节后的发射功率作为最终的发射功率。
可以理解的是，增加后的发射功率不超过功率调节装置正常工作所允许的最大值，默认的预设发射功率、预设阈值、增加的发射功率值可根据实际需求设置，此处不作限定。
可以理解的是，在本实施方式中，只设置了一个预设阈值，在其他实施方式中，也可以设置至少两个预设阈值，至少两个阈值构成至少三个区间，每个区间对应一个需要增加或减小的发射功率值，根据信号质量指标所属的区间调节发射功率。其中，预设阈值、每个区间对应的需要增加或减小的发射功率值根据实际需求设置。
S205：按所述调节后的发射功率发送信号。
功率调节装置按照调节后的发射功率发送信号，与网络中的终端设备进行通信。
上述方案中，通过根据终端设备发送的信号获取信号质量指标，并每隔第一预设时间内统计信号质量指标的最小值，每隔第二预设时间计算在第二预设时间内信号质量指标的最小值的平均值，根据当前信号质量指标的最小值的平均值调节发射功率，实现了功率调节装置根据终端设备的接收信号的信号质量指标动态调整发射功率，即使当功率调节装置所发送的信号受到环境干扰、以及信号强度受到墙壁等障碍物的阻隔而衰减时，也能保证终端设备的接收性能，进而增强通信的可靠性。
请参阅图3，图3是本申请又一实施方式的流程图。本实施方式从功率调节装置的角度出发进行描述，其中，功率调节装置可以是网关或者路由器。本实施方式包括如下步骤：
本实施方式与上一实施方式类似，其不同之处在于步骤S304，步骤S301~S303、S305请参阅步骤S201~S203、S205及相关描述，此处不再赘述。
S304：根据当前的平均值判断所述平均值所属的预设区间，并根据所述平均值所属的预设区间调节发射功率，其中，所述预设区间包括至少两个按预设规则排列的子区间，每个子区间对应一个发射功率。
当功率调节装置得到当前最小值的平均值后，根据当前最小值的平均值判断当前最小值的平均值所属的预设区间，并根据当前的最小值的平均值所属的预设区间调节发射功率，其中，预设区间包括至少两个按预设规则排列的子区间，每个子区间对应一个发射功率。
例如，当信号质量指标为信号质量值时：
第一子区间为【100，70】，且第一子区间所对应的发射功率为默认的预设发射功率(例如，默认的预设发射功率为13dBm）；
第二子区间为【69，50】，且第二子区间所对应的发射功率为14dBm；

第四子区间为【29，10】，且第四子区间所对应的发射功率为16dBm；
第五子区间为小于10，且第五子区间所对应的发射功率为17dBm。
如果当前的最小值的平均值为90，则功率调节装置判断该平均值属于第一子区间，不调节发射功率，即保持默认的预设发射功率13dBm。
如果当前的最小值的平均值为60，则功率调节装置判断该平均值属于第二子区间，将当前的发射功率调至14dBm。
如果当前的最小值的平均值为45，则功率调节装置判断该平均值属于第三子区间，将当前的发射功率调至15dBm。
如果当前的最小值的平均值为20，则功率调节装置判断该平均值属于第四子区间，将当前的发射功率调至16dBm。
如果当前的最小值的平均值为8，则功率调节装置判断该平均值属于第五子区间，将当前的发射功率调至17dBm。
当信号质量指标为噪声质量值时：
第一子区间为【100，70】，且第一子区间所对应的发射功率为17dBm；
第二子区间为【69，50】，且第二子区间所对应的发射功率为16dBm；
第三子区间为【49，30】，且第三子区间所对应的发射功率为15dBm；
第四子区间为【29，10】，且第四子区间所对应的发射功率为14dBm；
第五子区间为小于10，且第五子区间所对应的发射功率为默认的预设发射功率(例如，默认的预设发射功率为13dBm）。
如果当前的最小值的平均值为90，则功率调节装置判断该平均值属于第一子区间，将当前的发射功率调至17dBm。
如果当前的最小值的平均值为60，则功率调节装置判断该平均值属于第二子区间，功率调节装置将当前的发射功率调至16dBm。
如果当前的最小值的平均值为45，则功率调节装置判断该平均值属于第三子区间，功率调节装置将当前的发射功率调至15dBm。
如果当前的最小值的平均值为20，则功率调节装置判断该平均值属于第四子区间，功率调节装置将当前的发射功率调至14dBm。
如果当前的最小值的平均值为8，则功率调节装置判断该平均值属于第五子区间，功率调节装置不调节发射功率，即保持默认的预设发射功率13dBm。
可以理解的是，在本实施方式中设置了5个子区间，5个子区间按从高到低的预设规则进行排列，在其他实施方式中至少两个子区间也可以按其他预设规则排列，每个子区间对应的发射功率值可以按实际情况设置，并不限于本实施方式所公开5个子区间分别对应的发射功率值。
上述方案中，通过根据终端设备发送的信号获取信号质量指标，并每隔第一预设时间内统计信号质量指标的最小值，每隔第二预设时间计算在第二预设时间内信号质量指标的最小值的平均值，根据该平均值所属的预设区间调节发射功率，实现了功率调节装置根据终端设备的接收信号的信号质量指标动态调整发射功率，即使当功率调节装置所发送的信号受到环境干扰、以及信号强度受到墙壁等障碍物的阻隔而衰减时，也能保证终端设备的接收性能，进而增强通信的可靠性。
请参阅图4，图4是本申请再一实施方式的流程图。本实施方式从功率调节装置的角度出发进行描述，其中，功率调节装置可以是网关或者路由器，信号质量指标为信号质量值。本实施方式包括如下步骤：
本实施方式与上一实施方式类似，其不同之处在于步骤S404，步骤S401~S403、S405请参阅步骤S201~S203、S205及其相关文字，此处不再赘述。
S404：根据至少两个连续的平均值判断所述平均值的变化趋势，根据所述平均值的变化趋势调节发射功率。
当信号质量指标为信号质量值，功率调节装置得到当前最小值的平均值后，功率调节装置根据至少两个连续的最小值的平均值判断平均值的变化趋势，根据最小值的平均值的变化趋势调节发射功率，其中，变化趋势包括上升趋势、平稳趋势和下降趋势。
如果两个连续的最小值的平均值中，第二个最小值的平均值大于第一个最小值的平均值，则功率调节装置判断最小值的平均值的变化趋势为上升趋势。
如果两个连续的最小值的平均值中，第二个最小值的平均值等于第一个最小值的平均值，则功率调节装置判断最小值的平均值的变化趋势为平稳趋势。
如果两个连续的最小值的平均值中，第二个最小值的平均值小于第一个最小值的平均值，则功率调节装置判断最小值的平均值的变化趋势为下降趋势。
在本实施方式中，通过将第二个最小值的平均值与第一个最小值的平均值比较，从而判断最小值的平均值的变化趋势，并且将第一个最小值的平均值所对应的发射功率作为当前的发射功率，根据最小值的平均值的变化趋势，在当前的的发射功率的基础上增加或减小发射功率，增加或减小的发射功率值可根据实际情况进行设置。
例如，如果两个连续的最小值的平均值中，第一个最小值的平均值和第二个最小值的平均值均为100，则功率调节装置判断第二个最小值的平均值100为当前的平均值，且最小值的平均值的变化趋势为平稳趋势，此时，功率调节装置不调节发射功率，即保持默认的预设发射功率。
如果两个连续的最小值的平均值中，第一个最小值的平均值为80，第二个最小值的平均值为60，则功率调节装置判断第二个最小值的平均值60为当前的平均值，且最小值的平均值的变化趋势为下降趋势，此时，与最小值的平均值为80所对应的发射功率为当前的发射功率。由于，最小值的平均值的变化趋势为下降趋势，功率调节装置在当前的发射功率的基础上，增加发射功率，并将调节后的发射功率作为最终的发射功率。可以理解的是，增加后的发射功率不超过功率调节装置正常工作所允许的最大值。
如果两个连续的最小值的平均值中，第一个最小值的平均值为60，第二个最小值的平均值为90，则功率调节装置判断第二个最小值的平均值90为当前的平均值，且最小值的平均值的变化趋势为上升趋势，此时，与最小值的平均值为60所对应的发射功率为当前的发射功率。由于最小值的平均值的变化趋势为上升趋势，功率调节装置在当前的发射功率的基础上，减小发射功率，并将调节后的发射功率作为最终的发射功率。
如果两个连续的最小值的平均值中，第一个最小值的平均值为60，第二个最小值的平均值为100，则功率调节装置判断第二个最小值的平均值100为当前的平均值，且最小值的最小值的平均值的变化趋势为上升趋势，此时，与最小值的平均值为60所对应的发射功率为当前的发射功率。由于，最小值的平均值的变化趋势为上升趋势，而与最小值的平均值为100所对应的预设发射功率为默认的预设发射功率，因此，功率调节装置在将当前的发射功率调至默认的预设发射功率，并将调节后的发射功率作为最终的发射功率。
可以理解，在本实施方式中，根据两个连续的最小值的平均值判断平均值的变化趋势，在其他实施方式中也可以选取多个连续的最小值的平均值判断平均值的变化趋势，从而更准确地判断其变化趋势，进而提高功率调节装置的控制精确度。
上述方案中，通过根据终端设备发送的信号获取信号质量指标，并每隔第一预设时间内统计信号质量指标的最小值，每隔第二预设时间计算在第二预设时间内信号质量指标的最小值的平均值，根据当前信号质量指标的最小值的平均值的变化趋势调节发射功率，实现了功率调节装置根据终端设备的接收信号质量指标动态调整发射功率，即使当功率调节装置所发送的信号受到环境干扰、以及信号强度受到墙壁等障碍物的阻隔而衰减时，也能保证接收设备的接收性能，进而增强通信的可靠性。
请参阅图5，图5是本申请又一实施方式的流程图。本实施方式从功率调节装置的角度出发进行描述，其中，功率调节装置可以是网关或者路由器，信号质量指标为信号质量值。本实施方式包括如下步骤：
本实施方式与上一实施方式类似，其不同之处在于步骤S504，步骤S501~S504、S504请参阅步骤S201~S204、S205及其相关文字，此处不再赘述。
S504：根据当前的平均值判断所述平均值所属的预设区间，以及根据至少两个连续的平均值判断所述平均值的变化趋势；根据所述平均值所属的预设区间以及所述平均值的变化趋势，调节发射功率。
当信号质量指标为信号质量值，功率调节装置得到当前最小值的平均值后，功率调节装置根据当前的最小值的平均值判断当前的最小值的平均值所属的预设区间，以及根据至少两个连续的最小值的平均值判断最小值的平均值的变化趋势，根据当前的最小值的平均值所属的预设区间以及最小值的平均值的变化趋势，调节发射功率。其中，预设区间包括至少两个从高到低排列的子区间，每个子区间对应一个发射功率，变化趋势包括上升趋势、平稳趋势和下降趋势。可以理解的是，在本实施方式中，至少两个子区间可按从高到低的预设规则进行排列，在其他实施方式中，也可以按其他预设规则进行排列。
如果两个连续的最小值的平均值中，第二个最小值的平均值大于第一个最小值的平均值，则功率调节装置判断最小值的平均值的变化趋势为上升趋势。
如果两个连续的最小值的平均值中，第二个最小值的平均值等于第一个最小值的平均值，则功率调节装置判断最小值的平均值的变化趋势为平稳趋势。
如果两个连续的最小值的平均值中，第二个最小值的平均值小于第一个最小值的平均值，则功率调节装置判断最小值的平均值的变化趋势为下降趋势。
比如，第一子区间为【100，70】，且第一子区间所对应的发射功率为默认的预设发射功率(例如，默认的预设发射功率为13dBm）；
第二子区间为【69，30】，且第二子区间所对应的发射功率为14dBm；
第三子区间为小于30，且第三子区间所对应的发射功率为15dBm。
如果两个连续的最小值的平均值中，第二个最小值的平均值属于第一预设区间，无论最小值的平均值的变化趋势为上升趋势、平稳趋势、下降趋势，功率调节装置均不调节发射功率，使其保持为13dBm。
如果两个连续的最小值的平均值中，第二个最小值的平均值属于第二子区间，如果最小值的平均值的变化趋势为上升趋势，功率调节装置在14dBm的基础上将发射功率减少1dBm；如果最小值的平均值的变化趋势为平稳趋势，功率调节装置不调节发射功率，使其保持14dBm；如果最小值的平均值的变化趋势为下降趋势，功率调节装置在14dBm的基础上将发射功率增加1dBm。
如果两个连续的最小值的平均值中，第二个最小值的平均值属于第三子区间，如果最小值的平均值的变化趋势为上升趋势，功率调节装置在15dBm的基础上将发射功率减少2dBm；如果最小值的平均值的变化趋势为平稳趋势，功率调节装置不调节发射功率，使其保持15dBm；如果最小值的平均值的变化趋势为下降趋势，功率调节装置在15dBm的基础上将发射功率增加2dBm。可以理解的是，增加后的发射功率不超过功率调节装置正常工作所允许的最大值。
在本实施方式中，如果两个连续的最小值的平均值属于相同的子区间，则功率调节装置根据第二个最小值的平均值的变化趋势，在第一个最小值的平均值所对应的发射功率的基础上增加或减小发射功率。如果两个连续的最小值的平均值，属于不同的子区间，则功率调节装置根据第二个最小值的平均值所属的区间以及其变化趋势，在所属区间所对应的发射功率的基础上增加或减小发射功率。
例如，如果两个连续的最小值的平均值中，第一个最小值的平均值和第二个最小值的平均值均为100，则功率调节装置判断当前的平均值为100，并且当前的平均值属于第一子区间，其变化趋势为平稳趋势。此时，由于当前的平均值属于第一子区间，第一子区间所对应的预设发射功率为13dBm，且最小值的平均值的变化趋势为平稳趋势，因此功率调节装置不调节发射功率，即保持默认的预设发射功率13dBm。
如果两个连续的最小值的平均值中，第一个最小值的平均值为80，第二个最小值的平均值为70，则功率调节装置判断当前的平均值为70，并且当前的平均值属于第一子区间，其变化趋势为下降趋势，此时，由于当前的平均值属于第一子区间，第一子区间所对应的预设发射功率为13dBm，且最小值的平均值的变化趋势为下降趋势，因此不调节发射功率，即保持默认的预设发射功率13dBm。
如果两个连续的最小值的平均值中，第一个最小值的平均值为80，第二个最小值的平均值为85，则功率调节装置判断第二个最小值的平均值85为当前的平均值，并且第二个最小值的平均值属于第一子区间，其变化趋势为上升趋势，此时，由于当前的平均值属于第一子区间，第一子区间所对应的预设发射功率为13dBm，且最小值的平均值的变化趋势为下降趋势，因此不调节发射功率，即保持默认的预设发射功率13dBm。
如果两个连续的最小值的平均值中，第一个最小值的平均值为70，第二个最小值的平均值为65，则功率调节装置判断当前的平均值为65，并且当前的平均值属于第二子区间，其变化趋势为下降趋势，此时，由于第一个最小值的平均值属于第一子区间，当前的平均值属于第二子区间，第二子区间所对应的预设发射功率为14dBm，最小值的平均值的变化趋势为下降趋势，所以功率调节装置在14dBm的基础上将发射功率增加1dBm，并将15dBm作为最终的发射功率。
如果两个连续的最小值的平均值中，第一个最小值的平均值为50，第二个最小值的平均值为65，则功率调节装置判断当前的平均值为65，并且当前的平均值属于第二子区间，其变化趋势为上升趋势，此时，由于第一个最小值的平均值与当前的平均值均属于第二子区间，第二子区间所对应的预设发射功率为14dBm，最小值的平均值的变化趋势为上升趋势，所以功率调节装置在14dBm的基础上将发射功率减少1dBm，并将13dBm作为最终的发射功率。
如果两个连续的最小值的平均值中，第一个最小值的平均值为65，第二个最小值的平均值为65，则功率调节装置判断当前的平均值为65，并且当前的平均值属于第二子区间，其变化趋势为平稳趋势，此时，由于第一个最小值的平均值与当前的平均值均属于第二子区间，且最小值的平均值的变化趋势为平稳趋势，而第一个最小值的平均值65所对应的发射功率14dBm为当前的发射功率，所以功率调节装置不调节发射功率，将当前的发射功率14dBm作为最终的发射功率。
如果两个连续的最小值的平均值中，第一个最小值的平均值为65，第二个最小值的平均值为45，则功率调节装置判断当前的平均值为45，并且当前的平均值属于第二子区间，其变化趋势为下降趋势，此时，由于第一个最小值的平均值与当前的平均值均属于第二子区间，且最小值的平均值的变化趋势为下降趋势，而第一个最小值的平均值65所对应的发射功率14dBm为当前的发射功率，所以功率调节装置在14dBm的基础上将发射功率增加1dBm，并将15dBm作为最终的发射功率。
如果两个连续的最小值的平均值中，第一个最小值的平均值为45，第二个最小值的平均值为40，则功率调节装置判断当前的平均值为40，并且当前的平均值属于第二子区间，其变化趋势为下降趋势，此时，由于第一个最小值的平均值与当前的平均值均属于第二子区间，且最小值的平均值的变化趋势为下降趋势，并且，功率调节装置在前一次调节功率的过程中，使得最小值的平均值65最终所对应的发射功率为15dBm，所以，在本次调节功率的过程中，第一个最小值的平均值65所对应的发射功率15dBm为当前的发射功率，所以功率调节装置在15dBm的基础上将发射功率增加1dBm，并将16dBm作为最终的发射功率。
依此类推，此处不再一一赘述。
在本实施方式中，根据两个连续的最小值的平均值判断平均值的变化趋势，在其他实施方式中也可以选取多个连续的最小值的平均值判断平均值的变化趋势，从而更准确地判断其变化趋势，根据其变化趋势调节发射功率，进而提高功率调节装置的控制精确度，增加或减小的发射功率值可根据实际情况进行设置。
上述方案中，通过根据终端设备所发送的信号获取信号质量指标，并每隔第一预设时间内统计信号质量指标的最小值，每隔第二预设时间计算在第二预设时间内信号质量指标的最小值的平均值，根据该平均值所属的预设区间以及当前的平均值的变化趋势调节发射功率，实现了功率调节装置根据终端设备的接收信号质量指标动态调整发射功率，提高了功率调节灵敏度与准确度，即使当功率调节装置所发送的信号受到环境干扰、以及信号强度受到墙壁等障碍物的阻隔而衰减时，也能保证终端设备的接收性能，进而增强通信的可靠性。

例如，功率调节装置启动后，使用默认的预设发射功率进行工作。当终端设备需要接入功率调节装置时，向功率调节装置发送信号以请求接入该功率调节装置；或者，当终端已经接入功率调节装置后，终端可与功率调节装置进行信号交互。接收模块610接收终端设备发送的信号。
具体地，在本发明实施例中，接收模块610接收终端设备发送的信号。应当理解，该信号是终端设备发送的消息的传递形式，其是传递消息的载体，例如在本实施例中，该信号可以为电信号。进一步理解，终端设备发送的信号的本质是消息，消息为信号要传递的内容，其为信号的本质。即，在本发明实施例中，信号与消息是载体与内容、形式与本质的关系；换言之，接收模块610接收终端设备发送的信号，包括接收模块610接收终端设备发送的消息，后者为前者的一种具体实现方式，也是更为本质的一种实现方式。其中，在接收模块610接收终端设备发送的消息时，该消息可以为控制帧、管理帧、数据帧。其中，
控制帧包括：确认字符（Acknowledgement,ACK）帧、请求发送（Request to Send，RTS）帧、取消发送（Clear to Send,CTS）帧、省电轮询（Power Save-Poll，PS-Poll）帧等。管理帧包括：探测请求（Probe Request）帧、信标（Beacon）帧、身份验证（Authentication）帧、解除身份验证（Deauthentication）帧等。当功率调节装置与终端设备建立连接的过程中，接收终端设备发送的管理帧、控制帧；当功率调节装置与终端设备建立连接后进行数据传输时，接收终端设备发送的数据帧。当功率调节装置与终端设备建立连接的过程中，接收模块610接收终端设备发送的管理帧、控制帧，当功率调节装置与终端设备建立连接后进行数据传输时，接收模块610接收终端设备发送的数据帧。
接收模块610将接收的信号向获取模块620发送。
获取模块620用于根据接收模块610接收的信号获取信号质量指标，其中，信号质量指标用于标识终端设备接收到的该功率调节装置发送的信号的信号质量，信号质量值用于标识终端设备接收到该功率调节装置所发送的信号的质量，噪声质量值用于标识终端设备接收到的信号中的噪声。
比如，当获取模块620接收到接收模块610发送的信号后，根据该信号获取终端设备的接收信号的信号质量指标，其中，信号质量指标用于标识终端设备接收到的该功率调节装置发送的信号的信号质量，即，信号质量指标用于标识终端设备的接收信号的信号质量。信号质量指标可以包括信号质量值或噪声质量值，信号质量值用于标识终端设备接收到该功率调节装置发送的信号的质量，信号质量值可以包括信道质量值以及信号强度值，噪声质量值用于标识终端设备接收到的信号的噪声，噪声质量值可以包括噪声信号的信号强度值。在本实施方式中，调节模块620通过信号质量指标衡量终端设备的接收信号的信号质量。当信号质量指标为信号质量值时，信号质量指标的值越高表示终端设备的接收信号的信号质量越好；当信号质量指标为噪声质量值时，信号质量指标的值越高表示终端设备接收的信号中噪声信号的信号强度越强，信号质量越差。
例如，当信号质量指标为信号质量值时，如果信号质量指标为100，则表示终端设备的接收信号的信号质量为预设的理想参考值；如果信号质量指标为90，则表示终端设备的接收信号的信号质量为预设的理想参考值的90%。
当信号质量指标为噪声质量值时，如果信号质量指标为100，则表示接收到的信号都是噪声信号，接收信号的信号质量为0%；如果信号质量指标为90，则表示接收的信号中噪声信号为90%，信号质量为预设的理想参考值的10%。
获取模块620将获取的信号质量指标向调节模块发送。
调节模块630用于在获取模块620获取到信号质量指标后，根据信号质量指标调节发射功率。比如，调节模块630接收到获取模块620发送的信号质量指标后，将信号质量指标与预设阈值进行比较，并根据比较结果调节发射功率，将调节后的发射功率作为最终的发射功率。
当信号质量指标为信号质量值时，如果信号质量指标小于预设阈值时，则在原发射功率的基础上增加发射功率；如果信号质量指标大于或等于预设阈值时，则不调节发射功率。
当信号质量指标为噪声质量值时，如果信号质量指标小于或预设阈值时，则不调节发射功率；如果信号质量指标大于预设阈值时，则在原发射功率的基础上增加发射功率。
例如，当信号质量指标为信号质量值，预设阈值为90时，如果获取到的信号质量指标为95，则调节模块630判断当前的信号质量指标大于预设阈值，不调节发射功率，即保持默认的预设发射功率。如果获取到的信号质量指标为60，则调节模块630判断当前的信号质量指标小于预设阈值，在默认的预设发射功率的基础上增加发射功率。如果获取到的信号质量指标为90，则调节模块630判断当前的信号质量指标等于预设阈值，将当前的发射功率调至默认的预设发射功率。
当信号质量指标为噪声质量值，预设阈值为10时，如果获取到的信号质量指标为5，则调节模块630判断当前的信号质量指标小于预设阈值，不调节发射功率，即保持默认的预设发射功率；如果获取到的信号质量指标为20，则调节模块630判断当前的信号质量指标大于预设阈值，在默认的预设发射功率的基础上增加发射功率；如果获取到的信号质量指标为5，则调节模块630判断当前的信号质量指标等于预设阈值，将当前的发射功率调至默认的预设发射功率。
调节模块630将调节后的发射功率作为最终的发射功率。
可以理解的是，增加后的发射功率不超过功率调节装置正常工作所允许的最大值，默认的预设发射功率、预设阈值、增加的发射功率值可根据实际需求设置，此处不作限定。
可以理解的是，在本实施方式中，只设置了一个预设阈值，在其他实施方式中，也可以设置至少两个预设阈值，至少两个阈值构成至少三个区间，每个区间对应一个需要增加或减小的发射功率值，根据信号质量指标所属的区间调节发射功率。
调节模块630将调节后的发射功率值发送给发送模块640。
发送模块640用于按调节模块630调节后的发射功率发送信号。比如，发送模块640接收调节模块630发送的调节后的发射功率值，并按照调节后的发射功率发送信号，与网络中的终端设备进行通信。
上述方案中，通过根据终端设备发送的信号获取信号质量指标，并根据信号质量指标调节发射功率，实现了功率调节装置根据终端设备的接收信号的信号质量指标动态调整发射功率，即使当功率调节装置发送的信号受到环境干扰、以及信号强度受到墙壁等障碍物的阻隔而衰减时，也能保证终端设备的接收性能，进而增强通信的可靠性。
请参阅图7，图7是本申请功率调节装置另一实施方式的结构示意图。本实施方式的功率调节装置包括接收模块710、获取模块720、统计模块730、调节模块740、发送模块750。
本实施方式的功率调节装置与上一实施方式的功率调节装置类似，其不同之处在于增加了统计模块730，接收模块710、获取模块720发送模块750分别与上一实施方式中的接收模块610、获取模块620、发送模块640的功能基本相同，请参阅上一实施方式中的相关文字，此处不再赘述。
统计模块730用于每隔第一预设时间统计信号质量指标的最小值，并每隔第二预设时间计算信号质量指标的最小值的平均值。
比如，统计模块730每隔第一预设时间统计信号质量指标的最小值，并每隔第二预设时间计算最小值的平均值，其中，每隔第二预设时间对应一个最小值的平均值，并且按时间先后顺序顺次排列，排在后的平均值为当前的平均值。
例如，统计模块730每隔5秒钟统计一次终端设备的接收信号的信号质量指标的最小值，并每隔1分钟计算出在这一分钟内12个最小值的平均值。在本实施方式中，第一预设时间为5秒钟，第二预设时间为1分钟，可以理解的是，在其他实施方式中也可以设置为其他的时间值。统计模块730将最小值的平均值向调节模块740发送。
调节模块740具体用于，在统计模块730获取最小值的平均值后，根据最小值的平均值调节发射功率。
比如，当调节模块740接收到统计模块730发送的最小值的平均值后，将最小值的平均值与预设阈值进行比较，并根据比较结果调节发射功率，将调节后的发射功率作为最终的发射功率。
当信号质量指标为信号质量值时，如果调节模块740判断最小值的平均值小于预设阈值，则在原发射功率的基础上增加发射功率；如果调节模块740判断最小值的平均值大于或等于预设阈值，则在原发射功率的基础上发射功率。
当信号质量指标为噪声质量值时，如果调节模块740判断最小值的平均值小于或等于预设阈值时，则不调节发射功率；如果调节模块740判断最小值的平均值大于预设阈值时，则在原发射功率的基础上增加发射功率。
例如，当信号质量指标为信号质量值，预设阈值为90时，如果获取到的最小值的平均值为95，则调节模块740判断当前的最小值的平均值大于预设阈值，不调节发射功率，即保持默认的预设发射功率；如果获取到的最小值的平均值60，则调节模块740判断当前的最小值的平均值小于预设阈值，在默认的预设发射功率的基础上增加发射功率；如果获取到的最小值的平均值为90，则调节模块740判断当前的最小值的平均值等于预设阈值，将当前的发射功率调至默认的预设发射功率。
当信号质量指标为噪声质量值，预设阈值为10时，如果获取到的最小值的平均值为5，则调节模块740判断当前的最小值的平均值小于预设阈值，不调节发射功率，即保持默认的预设发射功率；如果获取到的最小值的平均值为20，则调节模块740判断当前的最小值的平均值大于预设阈值，在默认的预设发射功率的基础上增加发射功率；如果获取到的最小值的平均值为5，则调节模块740判断当前的最小值的平均值等于预设阈值，将当前的发射功率调至默认的预设发射功率。
调节模块740将调节后的发射功率作为最终的发射功率，并将调节后的发射功率值向发送模块750发送。
可以理解的是，增加后的发射功率不超过功率调节装置正常工作所允许的最大值，默认的预设发射功率、预设阈值、增加的发射功率值可根据实际需求设置，此处不作限定。
可以理解的是，在本实施方式中，只设置了一个预设阈值，在其他实施方式中，也可以设置至少两个预设阈值，至少两个阈值构成至少三个区间，每个区间对应一个需要增加或减小的发射功率值，根据信号质量指标所属的区间调节发射功率。其中，预设阈值、每个区间对应的需要增加或减小的发射功率值根据实际需求设置。
上述方案中，通过根据终端设备发送的信号获取信号质量指标，并每隔第一预设时间内统计信号质量指标的最小值，每隔第二预设时间计算在第二预设时间内信号质量指标的最小值的平均值，根据当前信号质量指标的最小值的平均值的变化趋势调节发射功率，实现了功率调节装置根据终端设备的接收信号的信号质量指标动态调整发射功率，即使当功率调节装置所发送的信号受到环境干扰、以及信号强度受到墙壁等障碍物的阻隔而衰减时，也能保证终端设备的接收性能，进而增强通信的可靠性。
请继续参阅图7，在另一种实施方式中，调节模块740具体用于，在统计模块730获取最小值的平均值后，根据当前的平均值判断平均值所属的预设区间，并根据平均值所属的预设区间调节发射功率，其中，预设区间包括至少两个按预设规则排列的子区间，每个子区间对应一个发射功率。
比如，当调节模块740接收到统计模块730发送的最小值的平均值后，根据当前的最小值的平均值判断平均值所属的预设区间，并根据当前的最小值的平均值所属的预设区间调节发射功率，其中，预设区间包括至少两个按预设规则排列的子区间，每个子区间对应一个发射功率。
例如，当信号质量指标为信号质量值时：
第一子区间为【100，70】，且第一子区间所对应的发射功率为持默认的预设发射功率(例如，默认的预设发射功率为13dBm）；
第二子区间为【69，50】，且第二子区间所对应的发射功率为14dBm；
第三子区间为【49，30】，且第三子区间所对应的发射功率为15dBm；
第四子区间为【29，10】，且第四子区间所对应的发射功率为16dBm；
第五子区间为小于10，且第五子区间所对应的发射功率为17dBm。
如果当前的最小值的平均值为90，则调节模块740判断该平均值属于第一子区间，调节模块740不调节发射功率，即保持默认的预设发射功率13dBm。
如果当前的最小值的平均值为60，则调节模块740判断该平均值属于第二子区间，调节模块740将当前的发射功率调至14dBm。
如果当前的最小值的平均值为45，则调节模块740判断该平均值属于第三子区间，调节模块740将当前的发射功率调至15dBm。
如果当前的最小值的平均值为20，则调节模块740判断该平均值属于第四子区间，调节模块740将当前的发射功率调至16dBm。
如果当前的最小值的平均值为8，则调节模块740判断该平均值属于第五子区间，调节模块740将当前的发射功率调至17dBm。
当信号质量指标为噪声质量值时：
第一子区间为【100，70】，且第一子区间所对应的发射功率为17dBm；
第二子区间为【69，50】，且第二子区间所对应的发射功率为16dBm；
第三子区间为【49，30】，且第三子区间所对应的发射功率为15dBm；
第四子区间为【29，10】，且第四子区间所对应的发射功率为14dBm；
第五子区间为小于10，且第五子区间所对应的发射功率为默认的预设发射功率(例如，默认的预设发射功率为13dBm）。
如果当前的最小值的平均值为90，则调节模块740判断该平均值属于第一子区间，将当前的发射功率调至17dBm。
如果当前的最小值的平均值为60，则调节模块740判断该平均值属于第二子区间，功率调节装置将当前的发射功率调至16dBm。
如果当前的最小值的平均值为45，则调节模块740判断该平均值属于第三子区间，功率调节装置将当前的发射功率调至15dBm。
如果当前的最小值的平均值为20，则调节模块740判断该平均值属于第四子区间，功率调节装置将当前的发射功率调至14dBm。
如果当前的最小值的平均值为8，则调节模块740判断该平均值属于第五子区间，功率调节装置不调节发射功率，即保持默认的预设发射功率13dBm。
可以理解的是，在本实施方式中设置了5个子区间，5个子区间按从高到低的预设规则进行排列，在其他实施方式中至少两个子区间也可以按其他预设规则排列，每个子区间对应的发射功率值可以按实际情况设置，并不限于本实施方式所公开5个子区间分别对应的发射功率值。
上述方案中，通过根据终端设备发送的信号获取信号质量指标，并每隔第一预设时间内统计信号质量指标的最小值，每隔第二预设时间计算在第二预设时间内信号质量指标的最小值的平均值，根据该平均值所属的预设区间调节发射功率，实现了功率调节装置根据终端设备的接收信号的信号质量指标动态调整发射功率，即使当功率调节装置所发送的信号受到环境干扰、以及信号强度受到墙壁等障碍物的阻隔而衰减时，也能保证接收设备的接收性能，进而增强通信的可靠性。
请继续参阅图7，在另一种实施方式中，当信号质量指标为信号质量值时，调节模块740具体用于，在统计模块730获取最小值的平均值后，根据至少两个连续的平均值判断平均值的变化趋势，根据平均值的变化趋势调节发射功率。
比如，当信号质量指标为信号质量值，调节模块740接收到统计模块730发送的最小值的平均值后，根据至少两个连续的最小值的平均值判断平均值的变化趋势，根据最小值的平均值的变化趋势调节发射功率，其中，变化趋势包括上升趋势、平稳趋势和下降趋势。
如果两个连续的最小值的平均值中，第二个最小值的平均值大于第一个最小值的平均值，则调节模块740判断最小值的平均值的变化趋势为上升趋势。
如果两个连续的最小值的平均值中，第二个最小值的平均值等于第一个最小值的平均值，则调节模块740判断最小值的平均值的变化趋势为平稳趋势。
如果两个连续的最小值的平均值中，第二个最小值的平均值小于第一个最小值的平均值，则调节模块740判断最小值的平均值的变化趋势为下降趋势。
在本实施方式中，通过将第二个最小值的平均值与第一个最小值的平均值比较，从而判断当前的平均值的变化趋势，并且将第一个最小值的平均值所对应的发射功率作为当前的发射功率，根据最小值的平均值的变化趋势，在当前的的发射功率的基础上增加或减小发射功率，增加或减小的发射功率值可根据实际情况进行设置。
例如，如果两个连续的最小值的平均值中，第一个最小值的平均值和第二个最小值的平均值均为100，则调节模块740判断第二个最小值的平均值100为当前的平均值，且最小值的平均值的变化趋势为平稳趋势，此时，调节模块740不调节发射功率，即保持默认的预设发射功率。
如果两个连续的最小值的平均值中，第一个最小值的平均值为80，第二个最小值的平均值为60，则调节模块740判断第二个最小值的平均值60为当前的平均值，且最小值的平均值的变化趋势为下降趋势，此时，与最小值的平均值为80所对应的发射功率为当前的发射功率。由于，最小值的平均值的变化趋势为下降趋势，调节模块740在当前的发射功率的基础上，增加发射功率，并将调节后的发射功率作为最终的发射功率。可以理解的是，增加后的发射功率不超过功率调节装置正常工作所允许的最大值。
如果两个连续的最小值的平均值中，第一个最小值的平均值为60，第二个最小值的平均值为90，则调节模块740判断第二个最小值的平均值90为当前的平均值，且最小值的平均值的变化趋势为上升趋势，此时，与最小值的平均值为60所对应的发射功率为当前的发射功率。由于最小值的平均值的变化趋势为上升趋势，调节模块740在当前的发射功率的基础上，减小发射功率，并将调节后的发射功率作为最终的发射功率。
如果两个连续的最小值的平均值中，第一个最小值的平均值为60，第二个最小值的平均值为100，则调节模块740判断第二个最小值的平均值100为当前的平均值，且最小值的最小值的平均值的变化趋势为上升趋势，此时，与最小值的平均值为60所对应的发射功率为当前的发射功率。由于，最小值的平均值的变化趋势为上升趋势，而与最小值的平均值为100所对应的预设发射功率为默认的预设发射功率，因此，调节模块740在将当前的发射功率调至默认的预设发射功率，并将调节后的发射功率作为最终的发射功率。
可以理解，在本实施方式中，根据两个连续的最小值的平均值判断平均值的变化趋势，在其他实施方式中也可以选取多个连续的最小值的平均值判断平均值的变化趋势，从而更准确地判断其变化趋势，进而提高功率调节装置的控制精确度。
上述方案中，通过根据终端设备发送的信号获取信号质量指标，并每隔第一预设时间内统计信号质量指标的最小值，每隔第二预设时间计算在第二预设时间内信号质量指标的最小值的平均值，根据当前信号质量指标的最小值的平均值的变化趋势调节发射功率，实现了功率调节装置根据终端设备的接收信号的信号质量指标动态调整发射功率，即使当功率调节装置所发送的信号受到环境干扰、以及信号强度受到墙壁等障碍物的阻隔而衰减时，也能保证终端设备的接收性能，进而增强通信的可靠性。
请继续参阅图7，在另一种实施方式中，当信号质量指标为信号质量值时，调节模块620，在统计模块730获取最小值的平均值后，具体用于根据当前的平均值判断平均值所属的预设区间，以及根据至少两个连续的平均值判断平均值的变化趋势，并根据平均值所属的预设区间以及平均值的变化趋势，调节发射功率。
比如，当信号质量指标为信号质量值，调节模块740接收到统计模块730发送的最小值的平均值后，根据当前的最小值的平均值判断当前的平均值所属的预设区间，以及根据至少两个连续的最小值的平均值判断最小值的平均值的变化趋势，根据当前的最小值的平均值所属的预设区间以及最小值的平均值的变化趋势，调节发射功率。其中，预设区间包括至少两个从高到低排列的子区间，每个子区间对应一个发射功率，变化趋势包括上升趋势、平稳趋势和下降趋势。可以理解的是，在本实施方式中，至少两个子区间按从高到低的预设规则进行排列，在其他实施方式中，也可以按其他预设规则进行排列。
如果两个连续的最小值的平均值中，第二个最小值的平均值大于第一个最小值的平均值，则调节模块620判断最小值的平均值的变化趋势为上升趋势。
如果两个连续的最小值的平均值中，第二个最小值的平均值等于第一个最小值的平均值，则调节模块620判断最小值的平均值的变化趋势为平稳趋势。
如果两个连续的最小值的平均值中，第二个最小值的平均值小于第一个最小值的平均值，则调节模块620判断最小值的平均值的变化趋势为下降趋势。
比如，第一子区间为【100，70】，且第一子区间所对应的发射功率为默认的预设发射功率（例如，默认的预设发射功率为13dBm)；
第二子区间为【69，30】，且第二子区间所对应的发射功率为14dBm；
第三子区间为小于30，且第三子区间所对应的发射功率为15dBm。
如果两个连续的最小值的平均值中，第二个最小值的平均值属于第一子区间，无论最小值的平均值的变化趋势为上升趋势、平稳趋势、下降趋势，调节模块740均不调节发射功率，使其保持为13dBm。
如果两个连续的最小值的平均值中，第二个最小值的平均值属于第二子区间，如果最小值的平均值的变化趋势为上升趋势，调节模块740在14dBm的基础上将发射功率减少1dBm；如果当前的平均值的变化趋势为平稳趋势，调节模块740不调节发射功率，使其保持14dBm；如果最小值的平均值的变化趋势为下降趋势，调节模块740在14dBm的基础上将发射功率增加1dBm。
如果两个连续的最小值的平均值中，第二个最小值的平均值属于第三子区间，如果最小值的平均值的变化趋势为上升趋势，调节模块740在15dBm的基础上将发射功率减少2dBm；如果最小值的平均值的变化趋势为平稳趋势，调节模块740不调节发射功率，使其保持15dBm；如果最小值的平均值的变化趋势为下降趋势，调节模块740在15dBm的基础上将发射功率增加2dBm。可以理解的是，增加后的发射功率不超过功率调节装置正常工作所允许的最大值。
在本实施方式中，如果两个连续的最小值的平均值属于相同的子区间，则调节模块740根据第二个最小值的平均值的变化趋势，在第一个最小值的平均值所对应的发射功率的基础上增加或减小发射功率。如果两个连续的最小值的平均值，属于不同的子区间，则调节模块740根据第二个最小值的平均值所属的区间以及其变化趋势，在所属区间所对应的发射功率的基础上增加或减小发射功率。
例如，如果两个连续的最小值的平均值中，第一个最小值的平均值和第二个最小值的平均值均为100，则调节模块740判断当前的平均值为100，并且当前的平均值属于第一子区间，其变化趋势为平稳趋势。此时，由于当前的平均值属于第一子区间，第一子区间所对应的预设发射功率为13dBm，且最小值的平均值的变化趋势为平稳趋势，因此调节模块740不调节发射功率，即保持默认的预设发射功率13dBm。
如果两个连续的最小值的平均值中，第一个最小值的平均值为80，第二个最小值的平均值为70，则调节模块740判断当前的平均值为70，并且最小值的平均值属于第一子区间，其变化趋势为下降趋势，此时，由于当前的平均值属于第一子区间，第一子区间所对应的预设发射功率为13dBm，且最小值的平均值的变化趋势为下降趋势，因此调节模块740不调节发射功率，即保持默认的预设发射功率13dBm。
如果两个连续的最小值的平均值中，第一个最小值的平均值为80，第二个最小值的平均值为85，则调节模块740判断第二个最小值的平均值85为当前的平均值，并且第二个最小值的平均值属于第一子区间，其变化趋势为上升趋势，此时，由于当前的平均值属于第一子区间，第一子区间所对应的预设发射功率为13dBm，且最小值的平均值的变化趋势为上升趋势，因此调节模块740不调节发射功率，即保持默认的预设发射功率13dBm。
如果两个连续的最小值的平均值中，第一个最小值的平均值为70，第二个最小值的平均值为65，则调节模块740判断当前的平均值为65，并且当前的平均值属于第二子区间，其变化趋势为下降趋势，此时，由于第一个最小值的平均值属于第一子区间，当前的平均值属于第二子区间，第二子区间所对应的预设发射功率为14dBm，最小值的平均值的变化趋势为下降趋势，所以调节模块620在14dBm的基础上将发射功率增加1dBm，并将15dBm作为最终的发射功率。
如果两个连续的最小值的平均值中，第一个最小值的平均值为50，第二个最小值的平均值为65，则调节模块740判断当前的平均值为65，并且当前的平均值属于第二子区间，其变化趋势为上升趋势，此时，由于第一个最小值的平均值与当前的平均值均属于第二子区间，第二子区间所对应的预设发射功率为14dBm，最小值的平均值的变化趋势为上升趋势，所以调节模块740在14dBm的基础上将发射功率减少1dBm，并将13dBm作为最终的发射功率。
如果两个连续的最小值的平均值中，第一个最小值的平均值为65，第二个最小值的平均值为65，则调节模块740判断当前的平均值为65，并且当前的平均值属于第二子区间，其变化趋势为平稳趋势，此时，由于第一个最小值的平均值与当前的平均值均属于第二子区间，且最小值的平均值的变化趋势为平稳趋势，而第一个最小值的平均值65所对应的发射功率14dBm为当前的发射功率，所以调节模块740不调节发射功率，将当前的发射功率14dBm作为最终的发射功率。
如果两个连续的最小值的平均值中，第一个最小值的平均值为65，第二个最小值的平均值为45，则调节模块740判断当前的平均值为45，并且当前的平均值属于第二子区间，其变化趋势为下降趋势，此时，由于第一个最小值的平均值与当前的平均值均属于第二子区间，且最小值的平均值的变化趋势为下降趋势，而第一个最小值的平均值65所对应的发射功率14dBm为当前的发射功率，所以调节模块740在14dBm的基础上将发射功率增加1dBm，并将15dBm作为最终的发射功率。
如果两个连续的最小值的平均值中，第一个最小值的平均值为45，第二个最小值的平均值为40，则调节模块740判断当前的平均值为40，并且最小值的平均值属于第二子区间，其变化趋势为下降趋势，此时，由于第一个最小值的平均值与当前的平均值均属于第二子区间，且最小值的平均值的变化趋势为下降趋势，并且，功率调节装置在前一次调节功率的过程中，使得最小值的平均值65最终所对应的发射功率为15dBm，所以，在本次调节功率的过程中，第一个最小值的平均值45所对应的发射功率15dBm为当前的发射功率，所以调节模块740在15dBm的基础上将发射功率增加1dBm，并将16dBm作为最终的发射功率。
依此类推，此处不再一一赘述。
可以理解，在本实施方式中，根据两个连续的最小值的平均值判断平均值的变化趋势，在其他实施方式中也可以选取多个连续的最小值的平均值判断平均值的变化趋势，从而更准确地判断其变化趋势，并根据其变化趋势调节发射功率，进而提高功率调节装置的控制精确度，增加或减小的发射功率值可根据实际情况进行设置。

处理器920根据接收器910接收的信号获取信号质量指标，并根据信号质量指标调节发射功率，其中，信号质量指标用于标识终端接收到功率调节装置发送的信号的信号质量，处理器920将调节后的发射功率值发送给发送器930。
发送器930按处理器920调节后的发射功率发送信号。
具体地，信号质量指标为信号质量值或噪声质量值，其中，信号质量值用于标识终端设备接收到功率调节装置发送的信号的质量，噪声质量值用于标识终端设备接收到的信号的噪声。
可选地，处理器920每隔第一预设时间统计信号质量指标的最小值，并每隔第二预设时间计算最小值的平均值，在获取最小值的平均值后，根据最小值的平均值调节发射功率。
具体地，处理器920在获取最小值的平均值后，根据当前的平均值判断平均值所属的预设区间，并根据平均值所属的预设区间调节发射功率，其中，预设区间包括至少两个按预设规则排列的区间，每个预设区间对应一个发射功率。
具体地，当信号质量指标为信号质量值时，处理器920在获取最小值的平均值后，根据至少两个连续的平均值判断所述平均值的变化趋势，根据平均值的变化趋势调节发射功率。
具体地，当信号质量指标为信号质量值时，处理器920在获取最小值的平均值后，根据当前的平均值判断平均值所属的预设区间，以及根据至少两个连续的平均值判断平均值的变化趋势，并根据平均值所属的预设区间以及平均值的变化趋势，调节发射功率，以保证终端设备的接收性能。
上述方案，通过根据终端设备发送的信号获取信号质量指标，并根据信号质量指标调节发射功率，实现了功率调节装置根据终端设备的接收信号的信号质量指标动态调整发射功率，即使当功率调节装置所发送的信号受到环境干扰、以及信号强度受到墙壁等障碍物的阻隔而衰减时，也能保证终端设备的接收性能，进而增强通信的可靠性。
而且，每隔第一预设时间内统计信号质量指标的最小值，每隔第二预设时间计算在第二预设时间内信号质量指标的最小值的平均值，根据该平均值所属的预设区间调节发射功率，或者根据该平均值的变化趋势调节发射功率，或者根据该平均值所属的预设区间以及该平均值的变化趋势调节发射功率，实现了接入点根据终端设备的接收信号的信号质量指标动态调整发射功率，提高了功率调节灵敏度与准确度，更进一步增强通信的可靠性。
可以理解的是，本申请所公开的实施方式中，信号质量值的最小值的平均值的所属的预设区间以及各预设区间所对应的发射功率均可以根据实际需要进行设置。
可以理解的是，本申请所公开的实施方式中，信号质量指标为信号质量值或噪声质量值，当信号质量指标为噪声质量值时，由于噪声质量值是随机的，其变化趋势不可预测，此时不能根据信号质量指标的最小值的平均值的变化趋势调节发射功率。在其他实施方式中信号质量指标也可以为其他的参数，具体的功率调节方式可根据实际情况参考上述实施方式，其中，当信号质量指标为随机的，不可预测其变化趋势的参数时，参考噪声质量值的实施方式，当信号质量指标的变化趋势可预测时，参考信号质量值的实施方式。
