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）

#ifndef SERVERWINDOW_H
#define SERVERWINDOW_H#include <QMainWindow>
#include <QTcpServer>
#include <QTcpSocket>
#include <QHostAddress> // 引入串口通信的两个头文件(第一步)
#include <QSerialPort> // 提供访问串口的功能
#include <QSerialPortInfo> // 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：

#include "serverwindow.h"
#include "ui_serverwindow.h"serverwindow::serverwindow(QWidget *parent) :QMainWindow(parent),ui(new Ui::serverwindow)
{ui->setupUi(this);setWindowTitle(tr("服务端"));
}serverwindow::~serverwindow()
{delete ui;
}//启动服务器
void serverwindow::on_pushButton_clicked()
{//第一步：创建对象  QTcpserver对象m_server= new QTcpServer(this);//第二步：监听 listen函数unsigned short port = ui->lineEdit->text().toShort();m_server->listen(QHostAddress::AnyIPv4 ,port);//第三步：处理信号槽函数处理 （槽函数中获取客户端的socket）QObject::connect(m_server,&QTcpServer::newConnection,this,&serverwindow::ClientConnect);//   nextpendingconnction函数可以获取到客户端的socket，也就是QTCPsocket对象//第四步：如果连接上了，设置按钮为灰色ui->pushButton->setEnabled(false);}
//发送数据
void serverwindow::on_pushButton_2_clicked()
{//使用write函数，QTcpsocket对象QString temp = ui->textEdit_2->toPlainText();//获取textedit的文本m_tcp->write(temp.toUtf8());if(!temp.isEmpty() ){ui->textEdit->append(temp);}ui->textEdit_2->clear();
}
//客户端连接后响应
void serverwindow::ClientConnect()
{//返回客户端的tcpm_tcp = m_server->nextPendingConnection();//打印下客户端的ip地址QHostAddress addr =  m_tcp->peerAddress();ui->textEdit->append(addr.toString());connect(m_tcp,&QTcpSocket::readyRead,this,&serverwindow::readData );connect(m_tcp,&QTcpSocket::disconnected ,this,&serverwindow::Clientdisconnect );}//服务器接受数据
void serverwindow::readData()
{QString temp = m_tcp->readAll();if(!temp.isNull()){ui->textEdit->append(temp);}
}
//客户端断开连接
void serverwindow::Clientdisconnect()
{ui->textEdit->append("客户端断开连接");m_tcp->close();ui->pushButton->setEnabled(true);ui->pushButton->setText("启动服务器");
}//刷新串口
void serverwindow::on_pushButton_5_clicked()
{//清空串口名ui->comboBox->clear();//遍历串口信息foreach(const QSerialPortInfo &info,QSerialPortInfo::availablePorts()){ui->comboBox->addItem(info.portName());}}//打开串口
void serverwindow::on_pushButton_3_clicked()
{m_serial.setPortName(ui->comboBox->currentText());//设置串口名m_serial.setBaudRate(ui->comboBox_2->currentText().toInt());//设置波特率m_serial.open(QIODevice::ReadWrite);if(m_serial.isOpen()){ui->label_7->setText("串口打开成功");connect(&m_serial,&QSerialPort::readyRead,this,&serverwindow::messlot);}else{ui->label_7->setText("串口打开失败");}
}//串口接受信息的处理函数
void serverwindow::messlot()
{QByteArray array = m_serial.readAll();ui->textEdit->insertPlainText(array);
}//关闭串口
void serverwindow::on_pushButton_4_clicked()
{m_serial.close();if(m_serial.isOpen()){ui->label_7->setText("串口关闭失败");connect(&m_serial,&QSerialPort::readyRead,this,&serverwindow::messlot);}else{ui->label_7->setText("串口已关闭");}
}

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）
