Design And Realization Of Drawing And Technical Document Management Information System In Engineering Institutes

The engineering drawing is the main technique document that designs a architectural design enterprise, not only is a architectural design enterprise technique development and the backlog of fulfillment for several years, more from now on continuously raise a comprehensive competition ability, rob the important foundation of having the market.Because the calculator of great majority architectural design enterprise manages now weaker, make a great deal of engineering drawing keep down by the form of paper quality document, accumulate over a long period, the amount is numerous, this brought many inconvenience:On the other hand the diagram paper file piles up to have great capacity and keeps a difficulty, along with practice of change, its technique loading the body(design diagram paper) be subjected to damage of different degree, many technique achievements therefore run off;Again on the other hand, the index of the paper quality design document is very difficult, can not carry out a technique set, for many design achievements of year agos or a lately usher in designer to say, almost and impossibly again make use of the achievement in past;On the other hand the paper quality diagram paper of then the utilization is usually low, design to need to make reference to past electronics diagram file in the process in the engineering.Because the calculator equipments leads go into, have already had a parts of architectural design enterprise's the adoption calculator to the saving design electronics text file currently, but asunder deposit in to design a personnel the electronics diagram amount of files within personal computer huge, can not carry on an unified management.The architectural design enterprise lacks to unify the effective means of management to the electronics diagram paper and cause electronics diagram the file constantly run off.Along with the extensive application of CAD technique, the calculator of the diagram paper text file's managing power is necessarily going. The this text author is persuing engineering for Master's period, architectural design enterprise diagram with solution the file manage have no the preface is to study a target and mainly developed " Design and realization of drawing and technical document management information system in engineering institutes ", and was physically producing to get a good application.The system with engineering institutes of area net in the bureau and Virtual Private Network (IPSEC VPN), Adopt customer to server structure, make use of Microsoft SQL Server 2005 with Visual C++6.0 Be develop tool, the former is used for a great deal of design diagram file information of electronical save and manage, the latter is amicably used for design to develop person's machine hand over interface with each other, and carry on a fast operation to the backstage database, both of the data connect a people's use of is ADO, use TCP/IP negotiate to carry out a data to deliver.The system provides a meticulous diagram file collections function, diagram label information to withdraw function for customer, efficiently search and browse function have already matched the management function of designing the process, have very strong function.Pass the implementation of this system, make the engineering institutes electronics diagram file management to get to basically present new look.Its design and realization have very high economic efficiency and social efficiency.Textual chapter 1 analyzed the present condition of the electronics diagram file in engineering institutes management and the problem of the existence first;In chapter 2, take actual technique development as a starting point, the research responds to technical development condition and its characteristics;In chapter 3, this text introduces the whole system frame of engineering institutes electronics diagram file management information system, and the function of each mold piece;Chapter 4 introduced the development way of thinking of backstage database;Chapter 5 outlined a system realization;In chapter 6, adopt MAC to bind to settle the method that combines together with VPN, carried out the diagram file management system of safe interview and economic practical another place backup saving technique, raised the safety, credibility of system;End carried on summary to the whole research and the development work.
