Railway Survey And Design Of Integrated Systems Research And Development

The design of Integrative in the survey of railway is a new work mode, which is based on digital information and is charactered with applying computer technology to all the survey and design course hence, The system should transform the data which include the railway line, geomorphology, geography, geologic and hydrology to digital information, then deal with the information in the interface and transmit it to the engineering database. In the new Integrative work mode, all the survey and design course can be considered as a course of gathering, processing and extending the digital information. The headstream of the digital information stream is the surveying and prospecting data in the field survey, the digital information stream are processed and extended by all the professional designer. The final digital information is the production and pigeonhole data.The paper is Mainly based on the basic principle of Integrative thesurvey and design of railway, It takes full applications of theorys andtechniques such as computer technology, digital image processingtechnology, database technology and GIS, at the same time,it combinedVisual Basic 6.0 of Object-Oriented Language and AutoCAD2002 ofFigure Software .Finally, It discusses the full process of the survey anddesign of Integrative. This paper mainly solves some problems as follow:1.establish DTM which are based on original discrete points andregular gridding points data.2.establish survey and design engineering database which are basedon the Middle-Small Relative DataBase Management System.3.use CAD to realize the main function of GIS and complete theinquiry and analysis of the figures and their attributes.4.Based on the analysis of the methods of traditional transect survey, coordinates survey of total station which takes use of coordinates shift under the control of independent reference frame is introduced into railway transect survey. Visual Basic 6.0 banding together with figure software AutoCAD 2002 in the indoor work successfully implements auto-Mapping of data in the transect survey.5.Based on the software engineering thoughts, combined Visual Basic 6.0 and AutoCAD 2002, we design an assistant software integrative of the survey of railway.
