摘　　要：该课题依托某舰型武器控制操作台上的雷达PPI显示,基于VxWorks操作系统平台,通过采用Qt跨平台的C++图形用户界面库,针对特定的设计需求和功能要求,在VxWorks操作系统下,采用多图层叠加的设计方式,合理分配与管理界面元素资源,基于Qt的信号与槽的消息传递机制,高效地完成消息响应,交互操作。实验表明,该软件设计思想和实现方法稳定可靠,效果良好,具有很好的易扩展性和可定制性。Relying on the radar PPI display on a ship type weapon control console,based on the VxWorks operating system platform,through the use of Qt cross platform C++graphical user interface library,according to the specific design requirements,under the VxWorks operating system,the design method of layer superposition is adopted to reasonably allocate and manage the interface element resources.The message response is completed efficiently based on the message transmission mechanism of Qt signal and slot,interactive operation.Experiments show that the software design idea and implementation method are stable and reliable,the effect is good,and has good scalability and customizability.
