DEVELOPMENT OF A PRESSURE PIPELINE ENGINEERING DRAWING AND ENGINEERING DATA MANAGEMENT SYSTEM BASED ON PROJECT MANAGEMENT

摘要

Pressure Pipeline, a kind of special pressure-containing equipment, is used as a absolutely necessarily and important component in various industries such as petroleum, chemical, metallurgic, electric power, and so on, also is applied widely in city gas and heat supply system. Pressure pipeline life-cycle management is a very important part of equipment management in a system even in the whole works. At present it is difficult to keep pressure pipeline engineering drawing and engineering data consistent in whole life-cycle management process of pipeline engineering data, especial in construction project management period, because of complicated piping system, large pipeline amount, various data resource and manual managing mode. In order to solve the ubiquitous problems of pipeline engineering management , a pipeline engineering information management mode base on pipeline engineering drawing is presented in this paper. According to this management mode a pipeline engineering drawing and engineering data management system based on project management is developed by using VBA for AutoCAD and database technology. It can draw pipeline engineering drawing conveniently and rapidly , and provides a visualizing, scientific and standardizing tool of pipeline engineering data management. By using pipeline graph information as its managing kernel so that pipeline engineering drawing and engineering data management can be unified. A self-expand subsystem is developed on VBE (Visual Basic Environment). It provides the graph constitutes self-expand function of pipeline engineering drawing subsystem. The system's framework adopts three-tiered application program architectures that makes the system has outstanding expandability and transplantability.
