Abstract:

 Based on the development trend of domestic intelligent pipeline construction and the existing pain points and difficulties in the improvement of system pipe network management in a large petrochemical enterprise, the design background of PN-MMS conceptual model is described. The distributed network topology and "Ethernet+CAN bus" composite technology are used, the service-oriented architecture concept and application integration technology are introduced to build basic development and data center functional framework, the data acquisition site layout principle is clarified, the system workflow and data acquisition and processing standard are formulated, and the mathematical model and logic algorithm of pipeline leakage are given. At the same time, the system pipeline survey and data cleaning are carried out based on business management and decision requirements, the database core assets are established, the system pipeline monitoring information system is built with application and problem solving as the value orientation, the traditional model based on experience is fundamentally changed, and a more safe, reliable, intelligent and efficient new model is explored. It has strong practicability in improving management system ability, promoting fine management and establishing systematic thinking.
