The invention relates to a self-adaption elevator fault early warning system based on multi-dimension failure characteristics. The self-adaption elevator fault early warning system comprises a data acquisition module for data acquisition, a data pretreatment module for treating the collected data, a characteristic constructing module, a model fitting module, an early warning module and a work order pushing module; the characteristic constructing module constructs additional characteristics according to basic data treated in the data pretreatment module; the model fitting module is used for training a data model to output an early warning model; the early warning module combines with real-time online elevator data according to the early warning model to judge whether to send an elevator fault early warning; and the work order pushing module intelligently delivers a work order according to a data combining area information given by the early warning module. The self-adaption elevator fault early warning system does not rely on an empirical rule and is high in early warning precision.

    本发明涉及一种基于多维故障的自适应电梯故障预警系统,系统包括:数据采集模块,用于数据采集;数据预处理模块,用于对采集到的数据进行处理;特征构造模块,根据预处理模块中处理好的基本数据构造额外的特征;模型拟合模块,用于训练数据模型输出预警模型;预警模块,根据预警模型结合实时线上电梯数据判断是否发出电梯故障预警;工单推送模块,根据所述预警模块给出的数据结合区域信息,进行智能工单派送。本发明的电梯故障预警不依赖经验规则,预警精度高。
