状态监测 vs 预测性维护

状态监测(CM)是对多个参数(如:设备振动和温度)的监测,以识别潜在的问题,如:偏离或轴承故障。当振动分析显示旋转设备部件的谐波频率发生变化时,状态监测工具便可绘制设备性能下降的映射图等。频率分析以振动计和麦克风数据为基础。

连续状态监测技术可应用于压缩机、泵、主轴和电动机等多台设备,还可用于识别机器出现的局部排放或真空泄漏等问题。

预测性维护以状态监测、异常检测和分类算法为基础,集成了预测模型,而该模型可以根据检测到的异常来估计机器的剩余运行时间。该方法可使用各种工具,例如:统计分析和机器学习,来预测设备的状态。

边缘处理的重要性

边缘处理的重要性

从设计智能传感器节点、配置运行在传感器节点和网关中的嵌入式软件,到开发集成在云端或公司企业资源规划(ERP)系统中的软件,实现预测性维护需要多种技术和能力。可以实施机器学习人工智能算法,以确保及早发现技术异常并优化设备正常运行时间。

智能传感器节点是预测分析的关键推动力。这些节点收集并记录经过预处理的安全数据,而这些数据将在可视化工具中显示并在其他处理算法中使用。智能传感器节点还可以通过减少计算延迟来处理数据并检测异常。例如,智能传感器节点可以检测到温度的小幅升高或突然升高,指示可能存在设备问题和未来的可靠性问题。

Gateways are either implemented to collect and process data from several smart sensor nodes or to act as a connectivity bridge to enable secure connection to the cloud using ethernet, Wi-Fi, cellular or LPWAN technologies.

Edge processing combines and distributes processing power among smart sensor nodes and gateways with the aim of sending the right data at the right time to enterprise-level systems where more advanced analyses can be performed. Processing at the Edge can also use Machine Learning and Artificial Intelligence (AI) algorithms to enhance smart sensor node and gateway mission profiles and to broaden the scope of anomaly detection and classification.
