Construction Project Information System Design And Implementation Of Datong-Xi'an High-speed Railway

August 1,2008 opening of the Beijing-Tianjin inter-city railway opened China's high-speed railway construction and operation of the curtain, marking a leap forward in China's economic re-development could begin. With China's high-speed railway construction project launched blowout-style, as well as high-speed railway construction required the continuous improvement of the railway construction quality and safety management more and more attention. This paper introduces the Datong-Xi'an high-speed railway Project's basic profile, and to major domestic passenger railway line construction project management information system introduced the use of, and analyzed the main problems encountered in use, thus expounded the Datong-Xi'an high-speed railway construction project information management, the need to put forward the objectives and principles of information system construction.This paper describes the construction of Datong-Xi'an high-speed Railway construction project information system used by the four key technologies, namely, B/S and C/S hybrid software architecture, bar code technology, geographic information technology and XML-based data exchange technology, combined with Datong-Xi'an high-speed railways project features selected for this project the use of information systems models. Article from Datong-Xi'an high-speed Railway Project organizational structure start with the main business of the construction project needs a detailed investigation, analysis summarized Datong-Xi'an high-speed railway construction project information system is mainly functional requirements, that is, material management, concrete mixing station management, and tunnel construction Statistical control and management personnel, Large-scale temporary facilities quality and safety management, and construction site video monitoring and management. After analyzing the needs of business processes, the from the network, business functions, data flow and database structure of the Quartet the face of information systems have been studied and proposed a feasible system design.For the Datong-Xi'an high-speed railway project characteristics and technical difficulties, articles, innovative in the system software architecture, using the B/S and C/S combination of software architecture, the system has great flexibility and scalability. In addition, the emphasis on analysis of information system user interface means, the underlying data collection methods, as well as with external information systems for data exchange between the implementations. Relying on Geographic Information System graphical interface research and design a friendly user interface; the data for the prevalence of false information systems and data distortion, explore the use of mechanical equipment, bar code, and other automated means of data entry, minimizing the information system data the degree of intervention; through a survey of existing information systems, information systems design of a large number of XML data exchange format used to solve the data exchange with external information systems issues, greatly optimizing the system structure...
