介绍了可以进行电话机原理仿真的教学软件的制作过程。软件实现了电位探针及元件故障设置的功能,与电子线路仿真软件Multisim7.0的电位探针类似,当鼠标移至节点附近时,同步显示该节点电位。软件在VC++6.0环境下制作完成,是基于MFC的单文档的应用程序。软件采用了Multisim7.0仿真导出的节点电位数据,通过读取保存的文件数据来实现显示节点电位的功能。
Introduced the making process of the teaching software which can simulate the telephone principle. The software realizes the function of the potential probe and component fault setting. Similar to the potential probe of the electronic circuit simulation software Multisim7.0, when the mouse moves to the vicinity of the node, the potential of the node is displayed synchronously. Software in the VC + +6.0 environment to complete the production is based on MFC’s single document applications. Software uses Multisim7.0 simulation derived node potential data, by reading the saved file data to achieve the function of display node potential.
