摘　　要：电梯的隐患故障与其运行状态存在着一定的关联性.根据电梯的组成要素、体现电梯健康状况表征,合理选择评价参数,基于logistic回归方法建立评价模型.通过分析评价模型基本原理,整合原始数据、引入惩罚因子、交叉验证、高阶拟线性等方法,解决了数据不均衡现状和差异性,提高了评价模型准确度,达到了对电梯健康实时监控并预警.There are some associations between potential failures and running states of elevators. According to the key elements of elevators, the assessment model based on logistic regression algorithm is established by choosing assessment parameters and characterization reflecting the status of elevators. Through analyzing the evaluating model＇s basic principles, preprocessing original data, introducing the methods of penalty factor, cross validation, and high order pseudo linear, unbalanced data and difference issues are solved, and the evaluating model＇s accuracy is improved, thus the realtime supervision and pre-warning of elevators＇ status are established.
