The invention relates to the technical field of elevator safety early warning, in particular to an elevator operation early warning method and a human body intercommunication elevator system applying the method. The method comprises the following steps: acquiring data during elevator operation; obtaining the centrifugal hammer wear degree every day; forming three-dimensional vector data by the real-time displacement, the real-time speed and the corresponding sound amplitude, obtaining a first convergence domain in the wear degree by performing phase-space reconstruction on the three-dimensional vector data, and screening reasonable data in the first convergence domain; acquiring a real-time speed loss factor according to a ratio of the wheel disc rotating speed to the real-time speed, taking a Gaussian model convergence domain of the speed loss factor as a second convergence domain, taking an intersection-to-union ratio of the first convergence domain and the second convergence domain as a rejection degree, and selecting effective data from the reasonable data; and the predicted abrasion degree is obtained through the effective data, abrasion monitoring is conducted on the speed governor, and elevator operation early warning is conducted based on the abrasion detection result. The abnormal state of the elevator speed governor can be detected in time, and operation safety of an elevator is ensured.

    本发明涉及电梯安全预警技术领域,具体涉及电梯运行预警方法及应用该方法的人体互通电梯系统。该方法采集电梯运行时的数据;获取每天的离心锤磨损程度;由实时位移、实时速度和对应的声音幅值组成三维向量数据,通过对三维向量数据进行相空间重构在磨损程度中获取第一收敛域,筛选第一收敛域中的合理数据;根据轮盘转速和实时速度的比值获取实时的速度丢失因子,以速度丢失因子的高斯模型收敛域作为第二收敛域,以第一收敛域和第二收敛域的交并比作为剔除度,在合理数据中选取有效数据;利用有效数据获取预测磨损程度,对限速器进行磨损监测,基于磨损检测结果进行电梯运行预警。本发明能够及时检测到电梯限速器的异常状态,确保电梯的运行安全。
