The invention discloses a method and system for monitoring the running state of an elevator. The method comprises the steps that acceleration data of an elevator car in the vertical direction in the state monitoring process are obtained; based on the sampling value of the acceleration data, dividing the acquired acceleration data into a plurality of sampling intervals in a time domain, and correspondingly classifying the acceleration data of each sampling interval into a positive acceleration interval, a zero acceleration interval and a negative acceleration interval; and one sampling interval and at least two sampling intervals located behind the sampling interval and adjacent to the sampling interval are selected according to the time sequence, and the elevator running state corresponding to the selected sampling interval is determined according to the type arrangement sequence of the acceleration data of the selected sampling interval. The invention further discloses a method and system for monitoring the states of the elevator parts. Whether the elevator parts break down or not is judged according to the acceleration data corresponding to the running states of all the elevators. According to the method, the running state of the elevator can be determined only by using the acceleration data, and the method has high universality and high accuracy.

    本发明公开了一种电梯运行状态的监测方法及系统,其中:获取状态监测过程中电梯轿厢在竖直方向上的加速度数据;以加速度数据的采样值为依据,将获取到的加速度数据在时域上划分为多个采样区间,并将各采样区间的加速度数据对应地分类为正加速区间、零加速区间、负加速区间;按照时序选取一个采样区间及位于该采样区间之后且与其相邻的至少两个采样区间,根据所选采样区间的加速度数据的类型排列顺序确定所选采样区间对应的电梯运行状态。本发明还公开了一种电梯零部件状态的监测方法及系统,根据各电梯运行状态所对应的加速度数据判断电梯零部件是否发生故障。本发明仅使用加速度数据就能确定电梯的运行状态,具有较强的通用性和较高的准确率。
