一、功能介绍
基于树莓派的智能家居。智能家居用到的硬件有：树莓派4B、LD3320语音识别模块、pi 摄像头、继电器组、小灯、火焰传感器、蜂鸣器、电磁锁
采用了简单工厂模式的一个设计方式。稳定，拓展性更强，在C语言中，因为没有接口、类这一说法，所以这里采用了结构体来“等效替换”。有四个灯，所以我创建了四个灯控制.c程序。每一个程序文件中，都有一个设备结构体，每个程序文件的函数实现方法不同，当有新设备进入只需要在创建一个.c文件，改变函数实现方法即可。初始化的时候，通过链表将各个模块连接起来（头插法）。在要使用某个模块时，只需要使用链表遍历，找到所需模块去调用功能
具体功能是：
1、可通过ld3320语音模块的口令模式，口令＋具体控制，通过串口把控制指令传给树莓派，来控制客厅、餐厅、二楼、浴室的灯
2、也可以通过socket客户端来发指令来控制灯的开关
3、火灾报警，当火焰传感器检测到火焰的时候，蜂鸣器会报警。
4、视频监控采用开源mjpg-Streamer来实现的，程序执行时创建一个视频监控的线程，用system函数调用启动脚本运行，监控画面可在http://172.20.10.8:8080去看到
5、人脸识别开锁，人脸识别功能是使用的翔云平台的人脸识别解决方案，需要安装libcurl 和 openSSl库来支持https协议，通过系统调用wget +http://172.20.10.8:8080/?action=snapshot -O ./huyu1.jpg 指令到树莓派的监控页面"去截取一帧保存到本地，获取图片的base64编码，工程文件夹下也有一张照片，huyu.jpg格式，相当于采集的人脸。也是获取图片的base64编码，通过sprintf函数将访问翔云需要的两张图片的base64编码与Key、secret、typeId、format拼接在一起，通过https协议去访问翔云平台， 识别成功后会将识别结果返回，通过回调函数readData将返回的字符串读到readBuff里，通过strstr去readbuff里找有没有字符’是’，如果识别成功就去控制电磁锁打开。

二、设计框图
