Pipeline Divulging Real-time Observation System's Design And Application

Oil and gas gathering and transportation company's existing oil pipeline 9, the total length of 473 km,the oil transmission capacity of around 1000×103t,to be able to real-time monitoring of the occurrence of the accident as soon as possible,set the leak point position,,Daoyou curb the phenomenon of crime,to prevent oil Losses,and safeguard the normal operation of pipelines,for which research and development of"long-distance pipeline leak real-time monitoring system for Development and Application".The system through the use of negative pressure transient wave method to conduct real-time monitoring of pipelines and the first time,using wavelet analysis signal processing methods, and accurately extracted from the noise signal, thereby greatly increasing leakage point positioning accuracy. System software is also part of GPS technology to unify all the base station computer time and call a dynamic way,every hour of time to conduct a correction to prevent computer chip time of drift and improve the reliability of the leak detection and location accuracy..Its leading technology in the domestic level. In liquid pipeline leak detection and location has broad prospects."Long-distance pipeline leak real-time monitoring system""in the long-distance pipelines on the application of alarm through the accurate and precise location information, the long-distance pipeline to conduct real-time monitoring..For many years to solve the problems of oil and gas gathering and transportation companies can not detect pipeline leakage problems. Suppression of illegal and criminal activities, avoid major vicious incidents,reduce environmental pollution,oil production for the normal operation,providing technical support.
