Abstract: In order to reflect the operation of the pipeline imaginably and intuitively, helping the decision-makers manage the pipeline scientifically, chart analysis model is built through investigation and needs analysis. With the design methods of software engineering, and taking the Visual Basic 2010 as a platform, the Microsoft chart controls and the SQL Server database connection technology are used to convert the actual operating data of the pipeline into charts. Accordingly, over 30 chart analysis modules of pipeline external detection are designed. Taking the two chart analysis modules (i.e. typical PCM and CIPS) as an examples, in view of the common elements of the charts, the basic process and principles of the design of the chart analysis module and the design ideas of warning and trend analysis mode are described. The deficiency of pipeline integrity management system and the prospect of future digital pipeline construction are pointed out.
