虚拟仪器测控系统图形用户界面设计

针对测控系统专业软件用户界面设计原则和方法缺乏可操作性的问题,采用界面像素分布图、设备图片按钮、ActiveX动画仿真技术和配色印象空间等方法,对虚拟仪器测控系统图形用户界面的设计进行了研究。应用上述方法设计了牧草种子加工成套设备测控系统图形用户界面,运行结果表明:图形用户界面可实时动画显示设备运行状态,故障信息能够及时地传递给操作人员;同时满足成套设备的联动控制和单体设备的单独控制;控制规律和参数可以通过界面方便的在线调节;一致性的配色方案和设备图片按钮使得软件界面在符合人机工程学设计思想的同时误操作减少。该方法在专业虚拟仪器测控系统图形用户界面的设计中,具有一定的借鉴作用。

Design of GUI on virtual instrument measurement and control system

The existing methodologies for software interface design have a poor operating characteristic when used in the software interface design of the virtual instrument M&C system.In the paper,the interface distribution,pattern button,ActiveX animated simulation technology and matching colors were introduced and a GUI of M&C system for the complete equipment of seeds based on LabWindows/CVI and Human-Computer Interface discipline was designed.This GUI can monitor the equipment operation state and error signals directly,control the whole system and separate equipment,regulate the control law and parameter on-line,and make operation convenient and reduce fault operations.This approach can be used as a guideline in the interface design of the virtual instrument M&C system.
