一、项���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）
#ifndef SERVERWINDOW_H#define SERVERWINDOW_H#include #include #include #include // 引入串口通信的两个头文件(第一步)#include // 提供访问串口的功能#include // 提供系统中存在的串口信息namespace Ui {class serverwindow;}class serverwindow : public QMainWindow{ Q_OBJECTpublic: explicit serverwindow(QWidget *parent = 0); ~serverwindow(); QTcpServer* m_server; //服务器对象 QTcpSocket* m_tcp; //客户端对象 QSerialPort m_serial;//串口private slots: //点击连接服务器 void on_pushButton_clicked(); //点击发送按钮 void on_pushButton_2_clicked(); //客户端连接上 void ClientConnect(); //有数据来了，则响应readyread信号 void readData(); //客户端断开连接 void Clientdisconnect(); //打开串口 void on_pushButton_3_clicked(); //关闭串口 void on_pushButton_4_clicked(); //串口接受信息的处理函数 void messlot(); //刷新串口 void on_pushButton_5_clicked();private: Ui::serverwindow *ui;};#endif // SERVERWINDOW_H 服务端.c文件：

2.客户端.h文件：需要在pro文件中加入serialport（TCP通信） sql（数据库） multimedia和 multimediawidgets（媒体，摄像头，音乐播放器）
