基于Qt4/Embedded的嵌入式数控系统GUI开发

摘要

由于嵌入式数控系统对软硬件资源及功耗均有限制,传统的图形用户界面系统不适用于嵌入式数控系统.将Qt4/Embedded用于嵌入式数控系统,通过Qt4/Embedded的信号与槽机制,并结合Qt4的C++类库,设计了轻量级人机界面系统,并已成功用于嵌入式数控系统中.通过Qt4/Embedded开发的人机界面具有占用系统资源少、功耗低等优点,适合于嵌入式数控系统.%Embedded numerical control (ENC) system has the limits of resources and power consumption, the tradi tional GUI was not suit for the ENC system. The ENC system GUI based on Qt4/Embedded was designed and im plemented by Qt4 signals and slots mechanism. This kind of GUI has been used successfully in the ENC system. The GUI based on Qt4/Embedded has advantages such as low system resource occupancy, low power consumption and so on, which is suitable for the ENC system.
