The invention relates to an elevator risk early warning method and device.The elevator risk early warning method comprises the steps that sample data are obtained, the sample data comprise sample sub-data corresponding to multiple maintenance periods of a sample elevator, risk labels of the sample elevator and fault sub-data corresponding to the sample sub-data, and the sample sub-data comprise sample basic sub-data and a weather data sequence; inputting each sample sub-data into a fault prediction sub-model in the risk early warning model to obtain a fault prediction value; the fault prediction sub-model inputs the feature information corresponding to each sample sub-data into a risk prediction sub-model in a risk early warning model to obtain a risk prediction value; adjusting parameters in the fault prediction sub-model according to the difference between each fault prediction value and the corresponding fault sub-data; adjusting the parameters of the risk prediction sub-model according to the difference between the risk prediction value and the risk label until a parameter adjustment stop condition is reached; and elevator risk early warning is carried out based on the risk early warning model obtained after parameter adjustment. The embodiment of the invention improves the prediction accuracy.

    本发明涉及电梯风险预警方法及装置,包括获取样本数据,样本数据包括样本电梯的多次维护周期分别对应的样本子数据、样本电梯的风险标签、样本子数据对应的故障子数据,样本子数据包括样本基础子数据和天气数据序列;将每一样本子数据输入风险预警模型中的故障预测子模型,得到故障预测值;故障预测子模型将各样本子数据分别对应的特征信息输入风险预警模型中的风险预测子模型,得到风险预测值;根据每一故障预测值与对应的故障子数据之间的差异调整故障预测子模型中的参数;根据风险预测值和风险标签之间的差异,调整风险预测子模型的参数,直至达到调参停止条件;基于调参后得到的风险预警模型进行电梯风险预警。本申请实施例提升预测准确度。
