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

1.其主界面见下图：



2.参数设置界面如下：



3.IO界面见下图：



4.手动操作界面如下所示：



5.MES对接界面：

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

include

include

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();

}`
