The invention provides an elevator emergency rescue data intelligent analysis and early warning method and system, and relates to the technical field of data analysis, and the method comprises the steps: collecting operation parameter data, carrying out preprocessing, carrying out local calculation through an elevator safety evaluation model, outputting a safety evaluation score, determining a safety level, and judging whether to trigger an early warning mechanism or not. If triggered, early warning information is sent, early warning information classification and summarization are carried out, a historical early warning data sequence is obtained, feature learning is carried out, deep features are generated, fault probability distribution is predicted, key omen factors are identified, and an elevator fault early warning report and a preventive maintenance strategy are generated; whether an alarm mechanism is triggered or not is judged, if yes, alarm information is sent, correlation matching, representation learning and semantic label information extraction are carried out, a graph-based Markov decision process is modeled, a fault diagnosis report is obtained through solving, and a rescue action combination is selected to obtain an initial rescue scheme; and an optimal rescue scheme is obtained through optimization and sent to a safety management department.

    本发明提供一种电梯应急救援数据智能分析与预警方法及系统,涉及数据分析技术领域,包括:采集运行参数数据,进行预处理,通过电梯安全评估模型进行本地计算,输出安全评估分值并确定安全等级,判断是否触发预警机制,若触发则发送预警信息,进行预警信息分类汇总,得到历史预警数据序列,进行特征学习,生成深层特征并预测故障概率分布,识别关键预兆因素并生成电梯故障预警报告和预防性维护策略;判断是否触发报警机制,若触发则发送报警信息,进行关联匹配,表示学习,提取语义标签信息,建模为基于图的马尔可夫决策过程并求解得到故障诊断报告,选择救援动作组合得到初始救援方案,优化得到最优救援方案并发送至安全管理部门。
