基于QT的全自动超声波焊接机上位机追溯系统(已经在设备上应用)

应用说明：
本上位机程序是我在做锂电池产线项目的时候开发的，用于采集设备数据以及实现设备自动控制，下位机采用基恩士PLC，超声波机采用上海一家的超声波焊接机，实现电芯极耳的自动焊接，上位在设备焊接过程中记录焊接数据，同时监控设备异常。
主要功能有：@1.设备监控；@2.PLC TCP/IP通讯；@3超声波焊接机通讯;@4扫码枪通讯；@5.用户登录方可有操作权限；@6数据采集；@7PLC控制；@8数据持久化等

 由于程序文件较大，所以这里只给出一些示例程序：
1.主程序如下：

include "messystem.h"
#include "appinit.h"
#include <QApplication>
#include <QTextCodec>
#include <QFile>

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

#if (QT_VERSION <= QT_VERSION_CHECK(5,0,0))
#if _MSC_VER
    QTextCodec *codec = QTextCodec::codecForName("gbk");
#else
    QTextCodec *codec = QTextCodec::codecForName("utf-8");
#endif
    QTextCodec::setCodecForLocale(codec);
    QTextCodec::setCodecForCStrings(codec);
    QTextCodec::setCodecForTr(codec);
#else
    QTextCodec *codec = QTextCodec::codecForName("utf-8");
    QTextCodec::setCodecForLocale(codec);
#endif

    //加载样式表
    QFile file(":/qss/psblack.css");
    if (file.open(QFile::ReadOnly)) {
        QString qss = QLatin1String(file.readAll());
        QString paletteColor = qss.mid(20, 7);
        qApp->setPalette(QPalette(QColor(paletteColor)));
        qApp->setStyleSheet(qss);
        file.close();
    }

    a.setFont(QFont("Microsoft Yahei", 9));
    AppInit::Instance()->start();

    UIDemo01 w;
    w.show();

    return a.exec();
}
