摘　　要：目的:在嵌入式的自助点菜系统中Qt平台下实现声音功能。方法:自助点菜系统硬件采用基于ARM9体系机构的Re-al2410开发板,移植Linux-2.6内核,用Qt/Embedded开发图形用户界面,在用户图形界面通过QSound类中成员函数void QSound::play()实现声音开始播放,用voidQSound::stop()实现声音停止播放。结果:当用户点击查看菜肴信息时,显示菜肴图片,自动播报用户点击的菜肴的名字,菜肴价格和菜肴特色。同时能够进行声音开始,暂停和返回上级菜单。结论:移植了Linux-2.6内核的Real2410开发板的自助点菜系统Qt平台下能够播报菜肴信息。In order to realize the sound function in the embedded system of self-service ordering system on the Qt.Through the method,in the self-service ordering system,hardware use Real2410 development board Based on the ARM9 system structure and transplant linux-2.6 kernel.And it develop graphical user interface through the Qt/Embedded.using QSound class to make sound play and pause.In the result,while the user click the food information.self-service ordering system show food picture,play the sound of the food informatio,at the same time,the user can choose to make the sound play,suspend or to return to the menu.In conclusion,self-service ordering system which transplant linux-2.6 kernel on the Qt can play the sound of the food information.
