这是一部分代码，之前没有过这种问题，就是点击开始时候，会用定时器采集数据发送数据

[jklinux]

楼主的硬件应是接上gprs模块吧， 如果确定代码没问题的话，建议用电流大点的电源来试下， 功率不够也会工作不正常的

[疯而不觉]

整个程序是这样的 我点击开始 程序定时器启动。然后运行线程去采集数据。之前没有这个问题 ，现在出现了。但是用以前没出问题的源码运行也是这样。所以我也不知道是程序还是硬件问题。

[军神关云长_大凡]

先确认是不是硬件问题，再看是不是代码问题。如果是硬件问题，你在代码这里找问题找死都找不到。可以通过其他方式确认一下硬件有问题。按你的说法是之前没问题的代码现在跑都有问题，我觉得很有可能就是硬件问题。

[疯而不觉]

硬件好像应该没问题

[Acuity.]

好像没问题？一定要百分百确定。 小学用的排除法很好使。

[lyz007]

确认一下系统有没有死机？有可能系统裁剪有问题

[春云者]

楼主问题解决了吗？我现在也遇到相似的问题，进入报文打印页面让报文实时刷新(1s一次)，刷新发生在QTextEdit组件上，运行一段时间后点击返回主界面就卡死了，此时Qt的其它响应是正常的，包括鼠标点击事件也能正常下发。除了界面死掉其它一切正常。我也找了无数资料没有发现问题，如果楼主解决了希望能不吝赐教，谢谢！
