摘要: 为提升深部钻探成套装备在极端工况下的安全可靠运行,面向集成自动化、数字化、多源传感与高可靠性设计的高端钻探装备,构建了“云-边-端”分布式协同的智能运维体系架构,提出钻探装备、数据采集、智能运维与数字孪生4层模块总体框架,设计基于MQTT与Kafka的数据流程,建立主题层级分类与消息体结构定义的数据建模策略,并采用边缘特征上报与云端按需采集机制以适应低带宽、高时延、间歇连接的网络条件. 该架构可支撑多源数据接入、跨井场统一部署与远程可视化交互,满足状态监测、故障诊断与预测性维护需求,为高端钻探装备智能运维平台设计与实现提供体系化参考.Abstract: To improve the safe and reliable operation of deep drilling equipment under extreme working conditions, this study focuses on high-end drilling equipment that integrates automated execution, digital control, multi-source sensing, and high-reliability design. A cloud-edge-end collaborative intelligent operation and maintenance (O&M) architecture is developed. The proposed architecture consists of four modules, namely the drilling equipment module, the data acquisition module, the intelligent O&M module, and the digital twin module. A data workflow based on MQTT and Kafka is designed. A data modeling strategy is established through hierarchical topic classification and message schema specification. An edge-side feature reporting mechanism and a cloud-side on-demand data acquisition mechanism are further introduced to cope with network conditions characterized by low bandwidth, high latency, and intermittent connectivity. The architecture supports multi-source data access, unified deployment across multiple drilling sites, and remote visualization and interaction. It meets the requirements of equipment condition monitoring, fault diagnosis, and predictive maintenance, and provides a systematic reference for the design and implementation of intelligent O&M platforms for high-end drilling equipment.
