 随着人工智能逐渐普及，人们对智能家居的需求越来越大，智能家居越来越多出现在人们的生活当中，不仅给人们带来便捷和舒适的体验，帮人们提供专属的服务，由于手动窗帘需要手动进行操作，而且有一定的不便性，由于窗帘在比较靠上，所以添加</span><span style="font-family:'宋体';">有害气体传感器来避免危险的滞后，保障人员的安全性，因此设计出</span> <span

style="padding-left:80px;">（1）手动模式：用户可根据语音或者红外遥控的方式对电机进行控制，也可以用语音询问语音助手当前的室内温湿度、室内光照、室外天气的状态。</p> <p style="padding-left:80px;">（2）自动模式：系统通过对光照和室外天气的采集进行数据处理，自动对窗帘进行打开和关闭的操作，无需用户的操作，其中光照的优先级最高，当光照高于设定值或者低于设定值时不再执行雨滴传感器的操作。</p> <p style="padding-left:80px;">（3）危险预警：危险预警功能不在任何模式之中，当检测到有害气体时，蜂鸣器就会鸣叫，自动模式和遥控没有权限关闭蜂鸣器，当检测到用户语音指令后才能关闭蜂鸣器。</p> <p style="padding-left:80px;">（4）数据上传：系统采集的数据会定时上传到阿里云物联网平台，其中时间是由定时器来进行控制，上传时间可根据用户的需求进行修改。</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt

style="font-size:14px;">整体结构：主控通过串口给ESP8266模块发送AT指令连接上阿里云物联网平台，定时将数据上传到阿里云物联网平台。主控通过不定时获取语音模块数据和红外模块数据对以下外设进行控制，定时对传感器进行数据读取和刷新，其中定时采用定时器进行时间计数，时间要求严格的在定时器中刷新，对于时间不严格的采用标志位进行刷新。</span></span></span></p>

 （2）流程图介绍：系统首先进行所有的外设进行初始化，随后等待ESP8266连接WIFI。首先主控会进行模式判断，在手动控制下会根据读取语音模块和红外模块的数据进行对外设进行控制。自动模式下根据光照和雨滴传感器进行数据的判断对外设进行控制。危险预警功能和手动模式和自动模式相互并不联系。所有外设的数据都会定时的刷新。</span></span></p> <p class="paragraph
