大型石化企业系统管网微机监测系统概念模型设计

CONCEPTUAL MODEL DESIGN OF PN-MMS FOR LARGE PETROCHEMICAL ENTERPRISES

基于国内智能管道建设的发展趋势和某大型石化企业系统管网管理提升存在的痛点、难点,阐述了管网微机监测系统(PN-MMS)概念模型设计背景。采用分布式网络拓扑结构和“Ethernet+CAN总线”复合技术;引入面向服务架构理念和应用集成技术搭建基础开发和数据中心功能框架;明确了数据采集站点布置原则;制定了系统工作流程和数据采集处理制式;给出了管道泄漏数学模型与逻辑算法。同时基于业务管理和决策需求开展系统管线普查和数据清洗,建立数据库核心资产,以应用和解决问题为价值导向构建系统管道监测信息化体系,从根本上改变以经验为主的传统模式,探索更加安全可靠、智能高效的新型模式,在提升管理体系能力、推进精细化管理、建立系统化思维等方面具有很强的实用性。

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.
