基於QT的全自動超聲波焊接機上位機追溯系統(已經在設備上應用)
應用說明：
本上位機程式是我在做鋰電池產線項目的時候開發的，用於採集設備數據以及實現設備自動控制，下位機採用基恩士PLC，超聲波機採用上海一家的超聲波焊接機，實現電芯極耳的自動焊接，上位在設備焊接過程中記錄焊接數據，同時監控設備異常。
主要功能有：@1.設備監控；@2.PLC TCP/IP通訊；@3超聲波焊接機通訊;@4掃碼槍通訊；@5.用戶登錄方可有操作許可權；@6數據採集；@7PLC控制；@8數據持久化等
1.其主介面見下圖：
2.參數設置介面如下：
3.IO介面見下圖：
4.手動操作介面如下所示：
5.MES對接介面：
由於程式文件較大，所以這裡只給出一些示常式序：
1.主程式如下：
`#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))

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
//載入樣式表
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();
}`
