- 摘要:
针对矿区埋地油气管道在扰动条件下状态识别滞后、响应机制缺失等问题,构建了具备连续识别与策略联动能力的监测系统。该系统分为状态感知、数据处理、策略执行与协同控制4层,采取多参量节点布控与滑窗提取管道状态特征,构建具备结构分层部署、感知节点协同、多参量融合判别与异常干预反馈功能的一体化智能监测系统,支撑非稳态过程识别与控制闭环。工程部署覆盖断层与埋深突变段,系统识别误差控制在0.3‰~0.9‰,断层段响应延迟583.99 ms,策略调用成功率92.96%。经连续运行5个月,人工检修频次下降57.14%,平均单次工时压缩至2.1 h,巡检干预比降低32.8%。结果表明:该系统具备适应扰动演化与动态调度能力,满足矿区非均匀荷载环境下的风险识别与响应控制需求,并可提升自演化路径控制能力。
Aiming at the problems of lagging state identification and the lack of a response mechanism of buried oil and gas pipelines in mining areas under disturbed conditions, a monitoring system with continuous identification and strategy linkage is constructed. The system is divided into four layers of state sensing, data processing, strategy execution, and coordinated control. Additionally, it adopts multi-parameter node deployment and sliding window modeling to extract state features and construct an integrated intelligent monitoring system with hierarchical structure deployment, sensing node coordination, multi-parameter fusion discrimination, and anomaly intervention feedback, supporting non-stationary process identification and closed-loop control. The project is deployed to cover faults and buried depth mutation segments, with a system identification error of 0.3‰ to 0.9‰, a fault segment response delay of 583.99 ms, and a strategy calling success rate of 92.96%. In five months of continuous operation, the manual maintenance frequency is decreased by 57.14%, the average working time is decreased to 2.1 h, and the inspection intervention ratio is decreased by 32.8%. The results show that the system can adapt to disturbance evolution and dynamic scheduling, meeting the identification and control needs in the non-homogeneous loading environment of mining areas, with an improved ability to self-evolve path control.
