About the integrated system , the three - tier architecture of the system based on the distributed technology and the technology of remote saving and reading of big non - structural data and the methods of second - time development of cad software catia v5 and seamless integration between the cad software and integrated intelligent design system based on ole automation are explained 在系统集成方面研究了基于分布式技术的三层体系结构、大型非结构化数据的远程存储和读取技术、基于ole自动化技术的catiav5的二次开发以及该软件与智能化设计系统集成的方法。
Here we study the method of using com subassembly and ole automation technology to solve the integrate problem . this technology can fulfill the task of data ' s sharing and conversion , supporting the synchronization of space decision reasoning analysis and space information manipulation , realizing the seamless integration . the paper based on solving the evaluation of land using problem , by anglicizing the deficiency of gis ' s space decision and the merit of egis 这里我作了用com技术及其统一数据传输机制和ole自动化功能进行es和gis集成的研究：其中，将es作为控制器， gis作为自动化对象连接起来，能很好地完成数据的转换与共享，支持空间决策推理分析和空间信息操作的同步进行，本文由此重点讨论了com及ole自动化技术。
While developing mapping system , a perfect mapping system can be finally accomplished with the method of the cross - platform ( using the gis software and visual language at the same tune namely ) to integrate all the advantages of each form so as to integrate friendly interface with powerfully mappings function 在开发制图系统时，采用跨平台的方法，即同时采用gis基础软件和可视化语言，集成各自的优点，可以整合友好界面与强大制图功能，开发出较完善的制图系统。 oleautomation (也称ole自动化)技术，是activex技术的核心。
The software of the chief station is composed of monitoring module and communicating module . the monitoring module involves the use of pc - labcards , the method of a precise timer , the principle of pid autocontrol and how to use it in the project , the realization of all kinds of reports with the ole automation skill , while the communicating module discusses the way of communication between the chief station and the scheduler based on the c / s structure . both monitoring module and communicating module are established on the database , so this paper particularly describes the access methods to ms sql server and the advantage of database stored procedure 论文先概要介绍了热网微机监控系统的需求分析和总体设计，然后在此基础上详细地阐述了首站软件实时监控模块和通信模块的实现细节，描述了工业采集卡的用法；提出了一种基于内核timer对象的精确定时方法；介绍了pid自动控制原理及其改进算法和现场控制参数的整定方法；用ole自动化技术扩充了visualbasic6 . 0的报表功能；在c / s用模型的基础上实现了首站和调度站的异步通信；讨论了visualbasic6 . 0对mssqlserver的数据存取方法和数据源驱动原理，在此基础上充分利用数据库存储过程完成了系统部分功能。
