智能家居客户端与服务器代码示例：Qt/C++ & C/Linux

{/'title/':/'智能家居客户端与服务器代码示例：Qt/C++ & C/Linux/',/'description/':/'本示例演示了基于Qt平台用C++开发的智能家居客户端，以及基于Linux/C语言的服务器端代码。客户端使用Qt实现登录注册、控制智能设备（灯、空调、加湿器、窗帘）、数据可视化等功能，服务器负责与客户端通信并存储数据到SQLite数据库，并提供数据可视化图表。/',/'keywords/':/'智能家居, Qt, C++, Linux, 服务器, 客户端, SQLite, 数据库, 可视化, 折线图, 登录, 注册, 控制, 设备, 温度, 湿度, 窗帘/',/'content/':/'// mainwindow.h//n#ifndef MAINWINDOW_H//n#define MAINWINDOW_H//n//n#include //n#include //n#include //n//nnamespace Ui {//nclass MainWindow;//n}//n//nclass MainWindow : public QMainWindow//n{//n Q_OBJECT//n//npublic://n explicit MainWindow(QWidget *parent = nullptr);//n ~MainWindow();//n//nprivate slots://n void on_loginButton_clicked();//n void on_registerButton_clicked();//n void on_lightSwitchButton_clicked();//n void on_lightIntensitySlider_valueChanged(int value);//n void on_acSwitchButton_clicked();//n void on_humidifierSwitchButton_clicked();//n void on_curtainSwitchButton_clicked();//n void on_curtainHeightSlider_valueChanged(int value);//n void on_modeComboBox_currentIndexChanged(const QString &mode);//n//nprivate://n Ui::MainWindow *ui;//n QTcpSocket *socket;//n QLineSeries *temperatureSeries;//n QLineSeries *humiditySeries;//n QChart *chart;//n QChartView *chartView;//n QSqlDatabase database;//n//n void connectToServer();//n void displayChart();//n void updateDatabase(double temperature, double humidity);//n};//n//n#endif // MAINWINDOW_H//n//n// mainwindow.cpp//n#include ///'mainwindow.h///'//n#include ///'ui_mainwindow.h///'//n//nMainWindow::MainWindow(QWidget *parent) ://n QMainWindow(parent),//n ui(new Ui::MainWindow)//n{//n ui->setupUi(this);//n socket = new QTcpSocket(this);//n//n // Connect signals and slots for socket communication//n//n connect(socket, SIGNAL(connected()), this, SLOT(connectToServer()));//n connect(socket, SIGNAL(readyRead()), this, SLOT(displayChart()));//n//n // Connect signals and slots for UI interaction//n//n connect(ui->loginButton, SIGNAL(clicked()), this, SLOT(on_loginButton_clicked()));//n connect(ui->registerButton, SIGNAL(clicked()), this, SLOT(on_registerButton_clicked()));//n connect(ui->lightSwitchButton, SIGNAL(clicked()), this, SLOT(on_lightSwitchButton_clicked()));//n connect(ui->lightIntensitySlider, SIGNAL(valueChanged(int)), this, SLOT(on_lightIntensitySlider_valueChanged(int)));//n connect(ui->acSwitchButton, SIGNAL(clicked()), this, SLOT(on_acSwitchButton_clicked()));//n connect(ui->humidifierSwitchButton, SIGNAL(clicked()), this, SLOT(on_humidifierSwitchButton_clicked()));//n connect(ui->curtainSwitchButton, SIGNAL(clicked()), this, SLOT(on_curtainSwitchButton_clicked()));//n connect(ui->curtainHeightSlider, SIGNAL(valueChanged(int)), this, SLOT(on_curtainHeightSlider_valueChanged(int)));//n connect(ui->modeComboBox, SIGNAL(currentIndexChanged(const QString &)), this, SLOT(on_modeComboBox_currentIndexChanged(const QString &)));//n//n // Initialize database//n//n database = QSqlDatabase::addDatabase(/'QSQLITE/');//n database.setDatabaseName(/'home.db/');//n//n if (!database.open()) {//n qDebug() << ///'Error: Failed to connect database.///';//n } else {//n QSqlQuery query;//n query.exec(/'CREATE TABLE IF NOT EXISTS users (id INTEGER PRIMARY KEY AUTOINCREMENT, username TEXT, password TEXT)/');//n query.exec(/'CREATE TABLE IF NOT EXISTS home_status (id INTEGER PRIMARY KEY AUTOINCREMENT, temperature REAL, humidity REAL, timestamp DATETIME DEFAULT CURRENT_TIMESTAMP)/');//n }//n}//n//nMainWindow::~MainWindow()//n{//n delete ui;//n}//n//nvoid MainWindow::on_loginButton_clicked()//n{//n // Handle login button click event//n}//n//nvoid MainWindow::on_registerButton_clicked()//n{//n // Handle register button click event//n}//n//nvoid MainWindow::on_lightSwitchButton_clicked()//n{//n // Handle light switch button click event//n}//n//nvoid MainWindow::on_lightIntensitySlider_valueChanged(int value)//n{//n // Handle light intensity slider value change event//n}//n//nvoid MainWindow::on_acSwitchButton_clicked()//n{//n // Handle AC switch button click event//n}//n//nvoid MainWindow::on_humidifierSwitchButton_clicked()//n{//n // Handle humidifier switch button click event//n}//n//nvoid MainWindow::on_curtainSwitchButton_clicked()//n{//n // Handle curtain switch button click event//n}//n//nvoid MainWindow::on_curtainHeightSlider_valueChanged(int value)//n{//n // Handle curtain height slider value change event//n}//n//nvoid MainWindow::on_modeComboBox_currentIndexChanged(const QString &mode)//n{//n // Handle mode combo box current index change event//n}//n//nvoid MainWindow::connectToServer()//n{//n // Connect to the server//n}//n//nvoid MainWindow::displayChart()//n{//n // Display the chart with temperature and humidity data//n}//n//nvoid MainWindow::updateDatabase(double temperature, double humidity)//n{//n // Update the database with temperature and humidity data//n}//n/
