一、项目简单总结下
1、项目实现的功能：
可以通过手机APP和语音控制家电，支持人脸识别开锁，视频监控防盗，以及内设有防火、防震警报。功能比较简单，因为某些模块的缺失，没有做的那么精致。还一个原因就是因为懒。。。
2、用到的模块：
这是一个简单的智能家居项目，主控芯片是树莓派3B-cortexA53，其它则是一些外设小芯片。有语音识别模块、摄像头、5V低电平触发继电器、继电器组合4只、电磁锁、微型震动传感器、火焰传感器、蜂鸣器、4只小型led灯。。。wemosD1和433M射频和红外编解码模块没用上。

其他的怎么接线我就不说了，可以自己去查。有实力可以玩玩家里的220V家电，不过要注意用电安全。
3、存在的疑点：
第一个：调用视频监控的时候，网页查看能显示视频监控。但是app的视频监控区显示不出来，说是版本太旧，还要自己去修改一下。
第二个：因为全部都是使用线程，当程序运行启动的时候，所有的线程都会去争夺资源运行。在这里每个线程都可以尝试加一个线程锁。但是当人脸识别线程启动的时候它就会先进行一次拍照然后实现人脸识别开锁功能，感觉这样太浪费了资源了。能不能像在小区门口一样的人脸识别开锁一样，它是人脸识别程序一直在运行，当捕捉到人脸的时候再识别进行开锁。不像自己写的这种还要拍照再进行识别比对开锁功能，有时候拍的照片还识别不出来。
后面有时间再修改下。
