用qt写一段代码实现同一个socket通讯创建两个独立的线程或进程，一个用于从socket接收特征值数据，另一个用于从socket接收实时波形数据

以下是用Qt实现创建两个独立线程通讯的示例代码：

#include <QCoreApplication>
#include <QTcpSocket>
#include <QThread>
#include <QDebug>

class FeatureThread : public QThread
{
    Q_OBJECT
public:
    explicit FeatureThread(QObject *parent = nullptr) : QThread(parent)
    {
        m_socket = new QTcpSocket(this);
    }

signals:
    void featureDataReceived(const QByteArray& data);

protected:
    void run() override
    {
        m_socket->connectToHost("127.0.0.1", 1234);
        if(m_socket->waitForConnected())
        {
            while(true)
            {
                if(m_socket->waitForReadyRead())
                {
                    QByteArray data = m_socket->readAll();
                    emit featureDataReceived(data);
                }
            }
        }
        else
        {
            qDebug() << "Failed to connect to host";
        }
    }

private:
    QTcpSocket* m_socket;
};

class WaveformThread : public QThread
{
    Q_OBJECT
public:
    explicit WaveformThread(QObject *parent = nullptr) : QThread(parent)
    {
        m_socket = new QTcpSocket(this);
    }

signals:
    void waveformDataReceived(const QByteArray& data);

protected:
    void run() override
    {
        m_socket->connectToHost("127.0.0.1", 5678);
        if(m_socket->waitForConnected())
        {
            while(true)
            {
                if(m_socket->waitForReadyRead())
                {
                    QByteArray data = m_socket->readAll();
                    emit waveformDataReceived(data);
                }
            }
        }
        else
        {
            qDebug() << "Failed to connect to host";
        }
    }

private:
    QTcpSocket* m_socket;
};

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    FeatureThread featureThread;
    WaveformThread waveformThread;

    QObject::connect(&featureThread, &FeatureThread::featureDataReceived, [](const QByteArray& data){
        qDebug() << "Received feature data: " << data;
    });

    QObject::connect(&waveformThread, &WaveformThread::waveformDataReceived, [](const QByteArray& data){
        qDebug() << "Received waveform data: " << data;
    });

    featureThread.start();
    waveformThread.start();

    return a.exec();
}

#include "main.moc"

这段代码创建了两个独立的线程 `FeatureThread` 和 `WaveformThread`，分别用于接收特征值数据和实时波形数据。在每个线程中，使用 `QTcpSocket` 连接到指定的主机和端口，并在接收到数据时发射信号。在主函数中，将接收到的数据通过连接到相应的信号槽来处理。

注意，这里简化了线程的退出逻辑。在实际应用中，需要考虑线程的安全退出。
