弧焊电源嵌入式测试设备的图形用户界面设计

随着嵌入式系统的发展,用于实现与用户交流功能的嵌入式图形用户界面成为研究中的一个重点.文中通过Qt/Embedded编程,以三星公司的S3C2410处理器设计的硬件系统为开发平台,为嵌入式弧焊电源测试设备设计了一款嵌入式图形界面.利用该界面通过多单片机协作实现对弧焊电源电参数的测量,可以通过这些电参数来评估被测弧焊电源的质量和产品性能.该系统实现了基于Linux下的串行通信,制定了相应的通讯协议和校验方法,保证了数据的有效传递.将串口接收到的电参数信息保存、显示,便于维护和管理,提高了测试效率.

GUI design of embedded testing apparatus for welding power source

With the development of embedded system,embedded graphics user interface(GUI) used for communication with users becomes one of research point.Based on S3C2410 development platform,a embedded GUI of testing apparatus for welding power source was designed under Qt/Embedded environment.With the help of the GUI,the electrical parameters of arc welding power could be tested by multi-microprocessor cooperation.The quality and performance of arc welding power supply could be evaluated by these electric parameters.The testing system achieved serial communication based on Linux,guaranteed transmission of data credible with correspondence communication protocol.Electricity parameters is saved and displayed ,which made maintenance more convenient and testing more effective.
