qt实现智能家居系统

一、项目介绍

          通过TCP/IP协议实现客户端和和服务端的链接，服务端和下位机通过串口通信的方式链接，传递信息，客户端通过账号登录进入进入智能家居服务系统，账号登录和QQ登录类似，我采用的是数据库的方式实现数据的存储和调用，界面使用qt-ui的方式进行建立，有摄像头操作，音乐播放器操作和视频操作，客户端通过按下开关的操作将json数据发送到服务端再经过串口的方式对下位机进行操作。

二、项目技术

qt-UI界面，c++，json，TCP/IP协议，摄像头，音乐播放器，视频操作，串口通信，stm32f407vet6。

三、项目内容

1.服务端头文件：需要在pro文件中添加 network（TCP数据链接） serialport（串口通信）

namespace Ui {
class serverwindow;
}
