| 摘 要： | MTU-5、V8、LEMI-417等大地电磁测深仪器的人机交互方式均基于文字,用户仅凭文字难以发现采集中的问题。由于示波器能把人眼无法直接捕捉到的电信号的时变规律以可见的图像形式显示出来,故将该技术应用于长周期大地电磁测深仪CLP中,使仪器的人机交互方式基于图形用户界面(GUI)。本系统的GUI选用Visual C++6.0作为开发工具,在规划了显示区域,建立了设备环境类CDC以及CPen、CBitmap等绘图工具类的对象后,设计了仿示波器界面,在示波器界面中,用MoveTo与LineTo函数实现了对采集数据的实时动态显示。此外,使显示窗口自适应显示器分辨率属性、信号最大化显示、显示背景设置为灰白色,以方便操作。经野外试验,该显示技术有助于用户对采集的数据进行分析,为下一步工作提供依据。

| Abstract: | During the implementation of the project ＂Deep Exploration Technology and Experimentation （ SinoProbe）＂ in China, the MT instruments MTU-5,V8 and LEMI-417 were used. However, their human-machine interface was based on character, which made it difficult to find useful information and faulty operation during data acquisition. The oscilloscope can display the law of the time-varying electrical signals that can not be captured by visual sense, so the technology is used in the CLP, a magnetotelluric instrument designed by an exploration party, which means its human-machine interface is based on graphics. The GUI is developed with Visual C＋＋ 6.0. Firstly, the display area of the screen is defined. Secondly, the objects of the class CDC （ Device Context） , CPen, and CBitmap are set up, and the virtual oscilloscope is designed with them. Then the collected data are displayed through graphics. Furthermore, the vir-tual oscilloscope can be adjusted automatically according to the monitor property. The experiments show that this display method can help the operator analyze the collected data and provide guidance for the next step. |
