Abstract

The invention provides an underground fuel gas pipe network safe evaluation system, equipped with fuel gas pipeline risk evaluation database and risk evaluation algorithm, and implementing fuel gas pipeline risk evaluation automated management, and comprising database maintaining module, data management module, evaluation record management module, evaluation record analysis module, pipeline graphics data module, C scan data management module, and weight regulating module. On the basis of building city fuel gas pipeline risk evaluation basic database, the management system of the invention closely combines with service flow of risk evaluation technique to implement scientific and automatic management of risk evaluation.

Description

technical field [0001] The invention belongs to the technical field of risk management of gas pipelines, in particular to a risk assessment method for gas pipelines based on the M Moser model. technical background [0002] With the continuous laying of oil and natural gas pipelines, the risk management of oil and gas pipelines has attracted worldwide attention. With the continuous development of the computer software industry, it has become a trend to carry out pipeline risk management in the form of computer software. [0003] Pipeline risk assessment technology is a new management technology developed abroad more than 30 years ago. Domestic research in this area mainly focuses on oil and gas pipelines and long-distance pipelines in oil fields, and there are few reports on urban buried gas pipeline networks. In addition, the evaluation techniques of developed countries are not suitable for China's national conditions. The present invention will learn from foreign advanced ...
