非授权用户有可能非法侵入;
AP不断的主动发送电波, 会消耗电力, 存在能源浪费;
产生电磁辐射;
对其他设备存在干扰。 发明内容 本发明的目的就是克服现有 WiFi设备技术忽视的缺点, 提供一种普遍用 户关注的功能进行改良, 来满足用户对 WiFi设备更加安全的使用需要。 为了 实现这个目的, 本发明采用的技术方案如下: 一种通过检测 WiFi信号来完成设备模式切换的方法, 包括以下歩骤: 歩骤 1: 以 MAC地址作为 WiFi终端识别标识, 设置授权 WiFi设备列表; 歩骤 2: WIFI 设备进入正常工作模式后, 检测模块检测周围是否存在无 线终端接入; 歩骤 3: 如果检测到无线终端或无线授权终端存在, 则 WIFI设备正常工 作, 并持续检测无线接入状态; 歩骤 4: 如果在 1-30分钟之内未检测到无线客户端的接入, 则由控制模 块关闭无线发射单元, 保留无线接收单元, 进入低功耗状态; 歩骤 5: 在低功耗状态下, 检测模块利用接收单元, 收集周围环境中的管 理帧, 并分析出无线终端 MAC地址, 把分析到的 MAC地址传递给授权模块进 行检测, 如果在授权设备列表中査询到该 MAC地址, 则由控制模块开启无线 发射单元, 使无线设备进入正常工作模式, 转到歩骤 2。 作为本发明的进一歩改进, 歩骤 4 中未检测到无线客户端的接入的时间 范围是 3分钟至 10分钟。 作为本发明的进一歩改进, 歩骤 5中所述管理帧为 802. 11管理帧。 通过检测 WiFi信号来完成设备模式切换的装置, 包括检测模块、 授权模 块、 存储模块、 控制模块、 发射单元、 接收单元; 检测模块检测周围是否有 无线终端的存在; 授权模块: 通过存取存储模块保存的授权终端信息, 判断 检测模块检测的无线终端是否为授权终端; 存储模块存取授权无线终端信息, 其中包含无线终端唯一标识-无线终端 MAC地址; 控制模块控制无线发射单元 的开启和关闭; 发射单元是 WIFI模块的发送部分; 接收单元是 WIFI模块的 接收部分。 作为本发明的进一歩改进, 所述检测模块如果在 1-30分钟之内未检测到 无线客户端的接入, 则由控制模块关闭无线发射单元, 保留无线接收单元, 进入低功耗状态。 作为本发明的进一歩改进, 所述检测模块如果在 3-10分钟之内未检测到 无线客户端的接入, 则由控制模块关闭无线发射单元, 保留无线接收单元, 进入低功耗状态。 作为本发明的进一歩改进,存储模块以 MAC地址作为 WiFi终端识别标识, 设置授权 WiFi设备列表。 本发明的有益效果是: 本发明, 在 AP检测到工作环境中无授权用户的情况下, 切换 AP设备到 节能模式: CPU频率减低; WiFi发送模块关闭, 同时保留 WiFi信号接收, 进 行接收信号扫描。 当 AP检测到授权 WiFi客户端发出的信号后, 立即开启 AP 相关功能让设备恢复正常工作模式。 本发明通过技术改良, 可以保障在授权用户不接入的情况下避免 WiFi受 攻击的威胁; 通过关闭发送逻辑单元, 对能耗是极大的节省, 具有极大的社 会意义; 对减少 WiFi设备爆炸性增长带来的相互干扰性问题和电磁辐射, 具 有积极的意义。 附图说明 图 1是本发明工作流图;
