【摘要】 如何利用计算机信息技术提高我国特种工业设备安全管理与监察工作水平是急需解决重大工程问题。本文采用Internet等信息系统开发技术，研究开发了基于Internet的压力管道远程使用登记系统，其主要研究工作包括：1．通过比较研究，采取C/S模式与B/S模式相结合的系统结构模式，开发了基 于Internet的压力管道远程使用登记系统，该系统由客户端软件和服务器 端软件组成，为我国压力管道的安全管理与监察提供了有效工具。2．研究了各种基于Internet的文件上载技术，开发了一个服务器端ActiveX 控件，并以基于HTTP协议的文件上载方式，实现了客户端的远程数据传输 功能。3．研究了数据压缩加密技术，并采用LZSS数据压缩算法和DES加密算法开发 了数据压缩加密软件，实现了本系统在数据文件远程传输之前的压缩与加 密，提高了系统在Internet网上的数据文件的传输安全性与传输效率。4．分析比较了各种Web访问数据库的解决方案，采用ASP技术开发研制了基于 B/S模式的服务器端压力管道注册登记管理系统。5．采用三层（多层）应用程序结构，开发研制了基于C/S模式的客户端压力管 道注册登记管理系统，具有突出的可扩展性和可移植性。6．研制了MAPI应用程序，使服务器端能够自动发送E_mail，实现对客户端上 载的数据文件的信息反馈。7．系统以防火墙技术实现了网络集成层的安全，以SSL技术保证传输安全，以 身份认证实现应用层的访问控制安全。更多还原

【Abstract】 In order to raise the management and supervising level of our country抯 special industry equipment, we develope the system of pressure pipeline抯 remote registration and management based on Internet in this paper. This paper抯 research is carried on: 1.. Based on the analysis of existing modes of management information systems, we introduce a new mode of the combination of Client/Server and Browser/Server architecture in this system according to requirement of the engineering. Therefore, the system is divided into client programs and server programs. This system provides an efficient tool for pressure pipeline抯 management. 2~ By analyzing the several methods of file transfer through Internet, we produce an ActiveX control to realize client抯 data transfer which is based on HTTP. 3.. The data file is compressed by the LZSS algorithm and is encrypted by the DES algorithm before being transferred to server while some principles of data compression and encryption are studied. 4.. Some solutions for the web database access are analyzed and the server programs which are based on Browser/Server architecture are designed by applying ASP. 5.. The client system which is based on Client/Server mode adopts three-tiered (multitiered) application program architectures that makes the system has outstanding expandability and transplantability. 6.. The MAPI application program is designed so that Email is automatically sent by exchange server to notify?client after the database file is transferred. 7.. The firewall technology is applied to solve the security problems of Internet., and the security of transport layer and application layer is ensured by using SSL and access control technology respectively.更多还原
