Industrial control computer and PLC state monitoring and early warning method and device

By dividing long-term data series into multiple data blocks using the PatchGRU model, and combining it with gated cyclic unit networks and hierarchical early warning thresholds, the problems of high complexity in long-term data series modeling and insufficient real-time early warning in industrial control systems are solved, enabling efficient monitoring and timely early warning of the status of industrial equipment.

Abstract

本公开属于核电技术领域，具体涉及一种工业控制计算机与PLC状态监测预警方法及装置。针对工业控制计算机与PLC设备在长期运行过程中存在的诸多问题，采集工业控制计算机与PLC的历史运行状态数据，并进行异常值处理、缺失值填补、标准化和归一化；采用滑动时间窗构造监督学习样本，并将长时间序列划分为多个连续Patch数据块，通过局部特征映射获得块级时序表示；再利用GRU对块级特征序列进行递推建模，提取跨Patch的长期依赖特征，并输出未来多个时刻的关键状态变量预测结果；最后，根据预测值与实时观测值之间的偏差建立多级预警机制，实现对突发故障和潜伏故障的提前识别。
