用“函数缝”方法设计多程控接口监控程序模块

Design Digital Oscilloscope Multi Interface Program by Function Interface

通过介绍、分析和比较数字存储示波器中RS232、局域网(LocalAreaNetwork,LAN)、通用接口总线(GeneralPurposeInterfaceBus,GPIB)、多接口程控的各种实现方法,着重论述和提出了一种结构清晰、易于扩展的实现多接口程控的编程方法——“函数缝”方法,给出了VisualC++开发环境下该方法的实现过程,并设计了相关接口动态链接库(DynamicLinkLibraries,DLL)。结果表明,“函数缝”方法便于新程控接口的扩展,同时简化了程序结构。

Many implementaion methods of multi interfaces programmable controlling are introduced in this paper. Multi interfaces include RS232, LAN and GPIB. By comparison of these different methods, ＂function interface＂ method is considered as an ideal method which has distinct architecture and is easy to be extended .The design of function interface is discussed in detail, and the implementation of multi interfaces DLL in Visual C＋＋ is put forward. By this method, it is easy to add new programmable interface and the program structure is simplified as well.
