| As a clean city energy natural gas has attracted more attention. In recent years, with the increasing demand for city gas, natural gas pipeline network Is expanding greatly. So how to monitor and manage the city gas pipeline network working condition is particularly important.. In this background, SCADA system play a key role in data acquisition, monitoring,controlling, scheduling and management of urban natural gas pipeline.The system includes data collection and process control systems, communication systems as well as network database as a platform for scheduling management system, integrates advanced, international-class field instrumentation and bus technology, automatic measurement and control technology, communication engineering technology, network database technology and SCADA/HMI application development technology, and is a high-level solution featuring high stability, high reliability, high performance/price ratio tailored for gas companies.The system is based on virtual server technology, designed with C/S and B/S combined architecture, developed with iFIX configuration software, and uses Oraclellg Enterprise Edition for data storage. System features include remote monitoring terminal for data acquisition and communications and dispatch center for data acquisition, data archiving, pipe network distribution, process flow charts, statistical report generation and printing etc.The project focuses on the actual needs of our company, carried out a detailed analysis of needs, and is accomplished from the user’s point of view combined with designer’s experience. To end with, the design, developed and implemented based on real systems, satisfied requirements, but will need continuous improvement in the future. |
