基于Windows下Qt与脉冲发生器的串口通讯实现

Implementation of Serial Communication to Pulse Generator Based on Qt in Windows Environment

摘要:

串口通讯在工业领域有着重要的作用,大部分工业设备都使用串口通讯和上位机远程通讯;VC6.0的简单易用在工业中经常被使用制作各种复杂的监控控制软件,但是VC的图形绘制、API接口功能和所制作软件移植性存在很多不方便的地方,该实现方法成功使用了VC嵌套Qt的方法解决了该问题；以脉冲发生器仪器为下位机举例,在Windows XP环境下,使用VC6.0嵌套Qt3.3,制作上位机RS232通讯控制图形软件;使用该软件通讯功能用户可以设置不同的脉冲发生器参数,输出不同的脉冲序列,该软件所使用的界面、线程、串口支持类全部由Qt支持,不使用MFC功能,最终完成软件编写;结果表明,在很低的电脑配置中,Windows环境下,使用VC嵌套Qt的方式也能快速的设计出一款界面完整、功能齐全、稳定性高、移植性强的工业控制软件。

Abstract:

Serial communication plays important role in industrial area,most of industrial equipment using serial communication connect to PC terminal. VC6.0 is easy to use in industry and often used to monitor variety complex software production,but VC has many inconvenient places in graphics rendering,API interface function and software portability.Implementation method successfully used VC nesting Qt way to solve this problem. Pulse generator equipment as lower-computer,for example,use VC6.0 nested Qt3.3,making PC graphics software by RS232 communication in Windows XP。Using communication users can set different parameters to let pulse generator outputs various pulse sequences.Interface ,thread and serial support classes of Software all supported by Qt not using MFC.Implementation finally completed software development. Results showed that low computer configuration,in Windows environment,using VC nested Qt way can quickly design a complete interface,full-featured,high stability,easy portability industrial control software.
