A visualized management system for oil and gas pipeline safety monitoring based on Internet of Things

It is difficult to realize real-time monitoring and accurate positioning in long distance oil and gas pipeline safety monitoring and management due to wide management range and long distance. For these prob-lems, a scheme of oil and gas pipeline safety monitoring system is proposed which is based on the technology of Internet of Things, such as sensor, communication and computer. The scheme effectively utilizes the mod-ern technology to monitor and manage long distance oil and gas pipelines. The system architecture, main components and basic principle are introduced. The safety monitoring sensor module in the system is inte-grated by the pressure sensor and the short-range communication module. Auxiliary and emergency monito-ring,including the vehicle inspection system and the miniature unmanned aircraft inspection system,forms a three-dimensional monitoring system for the pipeline. The optical fiber strain distribution method is adopted to locate the pipeline leakage at long distance, which both improves the positioning accuracy and takes the communication into account. Part of the scheme has been successfully applied in many engineering fields and meets the requirements of field monitoring and management. The application of the system is prospect.
