The invention discloses an elevator acceleration sensor data processing method. The elevator acceleration sensor data processing method includes the following steps that S1, an acceleration sensor collects vibration data during an elevator operation process according to a predetermined sampling frequency to obtain a vibration curve; S2, each peak value X in the vibration curve is read, that is, the maximum value and the minimum value in data are continuously sampled at each section and are sequentially recorded as X0, X1,..., X (n is a positive integer), and the data of the part are saved;S3, other data between the two consecutive X data are compressed; S4, Y values are selected and recorded as Y0, Y1,..., Y (m=n-1 and m is a positive integer), wherein Y=S*|X+1-X| (wherein, 0.1<=S<=1, 1<=K<=m and k is a positive integer); and S5, X0-X and Y0-Y are recombined into a new curve, and a new curve is combined according to a sequence of X0, Y0, X1, Y1,..., Y, X. The data can be effectively compressed, the key feature values of the data are saved, and the effectiveness and transmission efficiency of an elevator curve are ensured.
本发明公开了一种电梯加速度传感器数据处理方法,包括以下步骤:S1:加速度传感器按照预定采样频率采集电梯运行过程中的振动数据,得到振动曲线;S2:读取振动曲线中的各个尖峰值X,即每一段连续采样数据中的最大值和最小值,依次分别记作X,X,…,X(n为正整数),并将该部分数据保存;S3:将连续的两个X数据之间的其他数据进行压缩;S4:选取Y值,依次分别记作Y,Y,…,Y(m=n‑1且m为正整数),其中,Y=S*|X‑X|(其中,0.1≤S≤1,1≤K≤m且k为正整数);S5:将X~X和Y~Y重新组合成新的曲线,按照X,Y,X,Y,…,Y,X的顺序组合成新的曲线。本发明可以既有效压缩数据,又保存数据重点特征值,保证电梯曲线的有效性和传输效率。
