只connect了一次，只发送了一次Signal，但槽函数执行了9次

[Sean10]

#include "mainwindow.h"
#include <QApplication>
#include "centralairconditioner.h"
#include "databasecontrol.h"
#include "client.h"

centralAirConditioner airConditioner ;
int checkConnect;

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    client *x = new client;
    MainWindow *w= new MainWindow;;

    checkConnect = 0;
    //QThread *thread = new QThread(x);
    //x->moveToThread(thread);
    //thread->start();
    QObject::connect(&airConditioner, SIGNAL(SignalInit()), w, SLOT(Init()));
    //bool isConnected;
    QObject::connect(w, SIGNAL(DataLogin(QString, QString)), x, SLOT(Login(QString, QString)),Qt::DirectConnection);
    //qDebug() << "isConnected:" << isConnected;

    QObject::connect(x, SIGNAL(TransMainWindow(int, float, float)), &airConditioner, SLOT(RevState(int, float, float)));
    QObject::connect(x, SIGNAL(RefreshCost(QString, QString)), &airConditioner, SLOT(RevCost(QString, QString)));
    QObject::connect(&airConditioner, SIGNAL(SignalRequestEnd()), x, SLOT(SendRequestEnd()));
    //明明只连接了一次，但为什么槽函数却执行了多次呢？
    //QObject::connect(&airConditioner, SIGNAL(SignalRequest()), x, SLOT(SendRequest()));
    QObject::connect(&airConditioner, ¢ralAirConditioner::SignalRequest, x, &client::SendRequest, Qt::UniqueConnection);

    QObject::connect(&airConditioner, SIGNAL(SignalBlowSpeed()), x, SLOT(SendBlowSpeed()));

    QObject::connect(x, SIGNAL(SignalChangeTemperature()), &airConditioner, SLOT(ChangeTemperature()));
    QObject::connect(x, SIGNAL(SignalChangeBlowSpeed()), &airConditioner, SLOT(ChangeBlowSpeed()));
    //databaseControl database;
    QObject::connect(w, SIGNAL(SignalLogout()), x, SLOT(Logout()));
    QObject::connect(x, SIGNAL(SignalRefresh()), w, SLOT(Refresh()));

    if(!w->UserRegister())
    {
        w->close();
        //this->hide();
        //待修正关闭事件
    }
    //w->Init();
    //qDebug() << "test";
    w->show();
    w->ShowWidgetMain();
    return a.exec();
}

上面的是我的主函数，主要通过这里的connect来调用各个模块里的函数，我的主要模块是一个centralAirCondtioner，存储对数据的操作，client模块，用Tcp协议，发socket包给服务端操作，还有一个主界面MainWindow，界面。
现在就是主函数里

QObject::connect(&airConditioner, ¢ralAirConditioner::SignalRequest, x, &client::SendRequest, Qt::UniqueConnection);

这一行的信号和槽出现了问题，centralAirConditioner模块里的emit SignalRequest在调试的时候确定只执行了一次，即下面qDebug()里的制冷制暖只输出了一次，但在服务端我却收到了9次Request。

void client::SendRequest()
{
    QString a="request/"+QString::number(airConditioner.GetTemperature(), 'f', 2)+"/"+QString::number(airConditioner.GetWorkTemperature(), 'f', 2);
    socket->write(a.toLatin1());
}


void centralAirConditioner::ChangeWorkTemperature(float tmp)
{
    //qDebug() << __func__ << tmp;
    workTemperature = tmp;
    if(fabs(temperature - workTemperature) > 0.01) //当工作温度和房间温度不相等时
    {
            sendMux=1;
            if(temperature < workTemperature && workModel == 1) //满足制热条件
            {
                sendMux=2;
                emit SignalRequest();
                qDebug()<<"制热";

            }
            else if(temperature > workTemperature && workModel == 0) //满足制冷条件
            {
                sendMux=2;
                emit SignalRequest();
                qDebug()<<"制冷";
            }
            else
            {
                sendMux=0;
            }
            qDebug() << __func__ << "1" << temperature << workTemperature;
    }
    qDebug() << __func__ << "2 "<< temperature << workTemperature;
}

这说明你socket通信有问题，检查这块。

谢谢~不过我的服务端接收到的9次request是下面这样的

"request/25.00/24.00"
Get request_in 1
Get request _out 1
Get request 1
"request/24.90/24.00"
Get request _out 1
Get request 1
"request/24.80/24.00"
Get request _out 1
Get request 1
"request/24.70/24.00"
Get request _out 1
Get request 1
"request/24.60/24.00"
Get request _out 1
Get request 1
"request/24.50/24.00"
Get request _out 1
Get request 1
"request/24.40/24.00"
Get request _out 1
Get request 1
"request/24.30/24.00"
Get request _out 1
Get request 1
"request/24.20/24.00"
Get request _out 1
Get request 1
"request/24.10/24.00"

每一下发送socket，里面的变量都有被改变，我理解的更像是纯粹这个函数被调用了9次……请问还是我理解错了？
