我正在尝试读取串行数据以实时更新诊断页面。经过长时间的搜索，我找到了此代码，并且能够使其适用于我的代码。但是现在我的GUI将随机崩溃。有时它可以完美工作，有时它会随机崩溃。我知道这与它有关，因为我已将其注释掉，但从未使GUI崩溃。

我在Qt Designer中使用PyQt5。

谢谢您的帮助！

    signalExample = QtCore.pyqtSignal(int)

        while True:
            # Long running task ...
            rawserial = ser.readline()
            cookedserial = rawserial.decode('utf-8').strip('\r\n')
            datasplit = cookedserial.split(',')
            global temperature
            temperature = datasplit[0].strip('<')
            print(temperature)
            self.signalExample.emit(temperature)
            time.sleep(1)
