摘要
介绍某型电台示教系统的设计方法,详细说明系统的硬件和软件设计。为了达到更加直观、清楚地展现电台的工作过程,方便地进行性能测试和故障诊断的目的,提出将电台所有的结构和工作过程开放化、形象化的设计理念,采用将电台整体放大引出观测点的方法,使电台的各项功能、测试性能指标和信号波形能通过示教系统直观的展示。通过实验验证,该系统使用方便、性能稳定、工作过程形象直观,既能在教学中使用,也可用于测试和故障诊断。软件设计采用图形化程序语言LabVIEW作为软件的开发平台,并结合运用了数据库技术。
A method for designing a certain kind of radio teaching system is introduced. The design for both the hardware and the software are described in detail. A concept of opening and visualizing the structure and operation of the radio is proposed,to realize clear display of the operation and implement the capability test and fault diagnoses conveniently. Through magnifying the radio entirely and giving the observation points, the radio＇s features,testing specifications and signal waveform can be clearly demonstrated on the instruction teaching system. Experiments indicate that the system is easy - to - use and reliable in the operation,can be used in teaching,testing and fault diagnosis. LabVIEW as a graphical program language,is exploited to serve as platform in the software design,and database technology is also integrated.
