The characters , advantages , domestic and foreign status and developing direction of virtual instrument , are inroduced briefly . and the design process of control software of hptimi in the environment of labwindows / cvi is also presented . the primary data exchang mechanism among the contol units of hptimi and the corresponding program flow charts and their programmimg approaches are expatiated 论文通过简单分析虚拟仪器的特点及国内外研究现状和发展方向,详细阐述在labwindows / cvi环境下,高分辨率时间间隔测量仪控制软件设计过程,说明其主要的数据交互机制,给出相应的程序流程图和编程方法。
The development of geographic information system is a complicated process including very complex aspects : the data acquirement and validation , the expression of spatial relation and topological relation etc . it is a concerned question how to design and develop a stable , interactive , reuseable gis effectively . but there is often short of effective ways and means to realize these traits wholly 开发地理信息系统是一个复杂的过程，涉及非常复杂的方面：数据获得，验证，空间关系和拓扑关系表示等。如何高效地，科学地开发一个具有良好软件特性的gis是开发者关心的问题。然而，在gis软件设计过程中，常常需要整体开发思想指导，需要应用有效方法去实现gis软件的复用性，规范性，可交互性，可共享等特性。
The second , we researched object - oriented reuse that is base on software design pattern . we discussed the support of design pattern to reuse from object builder , object component and object alteration . , and described how to support transplant , expansibility , reuse of software during the design 其次，研究了基于设计模式的面向对象复用，从对象的创建、组合和交互三方面论述了设计模式对复用的支持，描述了在软件设计过程中，如何充分体现对软件移植性、扩展性和复用性的支持。
In the process of software designing , the windows software was chosen as the development platform , the visual c + + was chosen as the software development environment , makes advantage of the strong dll ( dynamic - link library ) function that the pci - 1710 provides to program , so the programming process was simplified and the utilization of the resources was raised 软件设计过程中,选择了windows软件开发平台,运用了visualc + +软件开发环境,充分利用pci - 1710提供的强大的dll (动态数据库)函数进行编程,简化了编程,提高了资源的利用率。
First introduces hardware platform of mine monitoring system that adopt embedded pcm - 3350 to be as main controller , big - capability memorizer cf card as memories , 10 . 4 inch lcd liquid crystal screen as display , pcm - 3612 as communication extend cell ; rs232 and keyboard as i / o interface to realize data dispose , storage and transport function , and so on . then introduces some basic concept and core character about embedded operating system windows ce . at the same time , the paper has a detailed introduction about platform - configured tool platform builder of mbedded operating system windows ce and a detailed narration abut the whole process of configuring the embedded operating system base on yanhua pcm - 3350 , then the paper depletes the characteristic function and system framework of embedded configuration software mcgs generally and introduces the design process about configuration software of mine monitoring - control system ; at last , the paper introduces main function of rk512 communication protocol that can ensure reliable communication with controller plc of bottom machine 首先介绍了硬件平台的搭建：采用嵌入式pcm - 3350作为主控制器；大容量的存储器cf卡作为存储设备；采用10 . 4寸lcd液晶屏作为显示设备； pcm - 3612作为通信扩展单元；用rs232和键盘作为i o接口来实现数据的处理、存储和传输等功能；然后又介绍了嵌入式操作系统windowsce的一些基本概念、核心特性，同时对嵌入式操作系统windowsce的平台定制工具platformbuilder做了一些介绍并详细叙述了使用platformbuilder定制基于研华pcm - 3350的windowsce操作系统的过程；接着概括叙述了可运行在windowsce上的嵌入版组态软件mcgs的特点、功能、体系结构并详细介绍了矿山检测系统的组态软件设计过程；最后介绍了能够与下位控制器plc可靠通讯的rk512通讯协议的主要函数。
