摘要
Intranet(企业的内部网)是将Internet技术引入现存的企业的网络，能更好地满足企业的经营和发展需求的一种新型网络，近两年已经得到了迅速的发展。将Intranet方式引入电厂管理信息系统中，建立全省甚至全国的电力企业信息网络，可以实现将来整个电力系统信息共享、互相协作、统一调度、统一指挥，具有重大的意义和非常广泛的应用前景。
本文主要工作是：基于Intranet的电厂MIS应用软件的开发，即Web技术的实现电厂邮件系统、多媒体会议系统以及网络远程访问的通信系统的设计与创建。取得了下列主要成果：
1．通过各种Web数据库访问方法的研究比较，选用ASP与ADO结合的方式，成功解决了Web页面与异构、异种数据库的连接，这是用Internet方式构造MIS系统的关键。
2．深入到Exchange系统的核心，利用ASP与Exchange提供的ActiveMessaging组件进行系统Web页面的开发，实现了MIS应用程序与电子邮件服务的结合，大大增强了系统应用的灵活性和方便性。这是本文的主要特色。
3．实现了Web与Office的无缝结合，并利用VEA项目的开发，丰富了Web的功能，弥补了Web的不足，充分发挥了Office软件的作用。
4．利用微软Exchange系统及客户端的Outlook Express建立了电力企业的内部网中的电子邮件系统，利用NetMeeting软件开发出多媒体会议系统，通过NT提供的RAS和拨号网络实现了电力企业的远程访问，并利用PCANYWHERE软件实现了远程控制。
这些成果已成功运用于电厂信息化管理之中，效果很好，有广泛的应用前景。
Intranet is a new-style network, which can meet the needs of enterprise management and development It is based on the Internet technique, and it has been developed rapidly in recent years. To build the Intranet-based electric power enterprise information network in the whole province and even the whole country, this will autualize the information sharing, collaboration and united superintending in the whole electric power system.
It has great significance and united superintending in the whole electric power system. It has great significance and excellent prospects.
The most works of this paper include the exploitation of the Intranet-based electric power plant MIS application software, that is the implement of the Web technique, and the establishment of the e-mail system, multimedia network meeting system and remote access service in the Intranet of the electric power plant. And the most results of the paper are as follows:
1. Compared with every method of connecting the Web with different kinds of database, this paper chooses the most proper one, which combines ASP with ADO, from these methods to settle this key problem of building Intranet-based MIS successfully.
2. It goes deep into the Exchange system and develops the Web making use of ASP and ActiveMessaging which is provided by the Exchange Server. By this way, it combines the MIS application with the e-mail services, and buildup the flexibility and the convenience of the MIS. This is the main new idea brought forth in the paper.
3. It realizes the combining of the Wreb with the software of Office perfectly and uses VBA to enrich the function of the Web, and makes up the shortages of the Web and make most use of the software of the Office.
4. It establishes the e-mail system based on the Exchange Server and the
Outlook Express, and the multimedia network meeting system by NetMeeting. At the same time, it realizes this remote access of the network by the RAS and the dial-up network, which are provided by windows NT. And it actualizes the remote control by the PCANYWHERE.
Those results have successfully used in the whole electric power information system , the result is very fine and it has excellent prospects.
