The invention discloses a safety early warning method for an elevator. The safety early warning method comprises the following steps that a prediction model is constructed on the basis of basic information of an existing elevator; then taking the date of the day as a time slice, and extracting and preprocessing the basic information of the elevator to be predicted by the prediction model; classifying various basic information of the elevator according to information types to generate feature vectors of the elevator; independently scoring each feature vector by the prediction model; scoring and rating each elevator single risk index of the to-be-predicted elevator according to the score of each feature vector, and scoring and rating the elevator comprehensive risk index according to the score of each elevator single risk index. And generating an elevator safety health report including the elevator single risk index score, the elevator single risk index grade, the elevator comprehensive risk index score and the elevator comprehensive risk index grade. According to the method, the prediction accuracy of the elevator risk level can be effectively improved.

    本发明公开了一种电梯的安全预警方法,包括以下步骤:以现有电梯的基本信息为基础构建预测模型;然后以当天日期作为时间切片,由预测模型对待预测电梯的基本信息进行提取和预处理;再按照信息类型对电梯的各项基本信息进行归类,生成电梯的特征向量;再由预测模型对各特征向量进行单独打分;再根据各特征向量的得分对待预测电梯的各电梯单项风险指标进行打分和评级,再根据各电梯单项风险指标的得分对电梯综合风险指标进行打分和评级,生成包含电梯单项风险指标分值、电梯单项风险指标等级、电梯综合风险指标分值和电梯综合风险指标等级的电梯安全健康报告。本发明能够有效提高对电梯风险等级的预测准确率。
