Embodiment
[0016] An embodiment, a method for real-time monitoring of the operating state of construction machinery, using a six-axis sensor to collect the angular velocity and acceleration on the three axes of the construction machinery at a frequency of 100 Hz;
[0017] For angular velocity, X fixed windows are taken sequentially on each axis, and A angular velocity data are collected in each fixed window, and the data in each fixed window is used to subtract the median of the data in the respective windows, and the obtained difference is taken as absolute Value, take the average of the obtained absolute values; then add the three averages of the corresponding windows of the three axes into a sum value; thus, to obtain X sum values, take the 0.75th percentile of the X sum value array Number (the 0.75 quantile of an array refers to the number that ranks in three quarters after the array is arranged from small to large. For example, a set of 40 numbers from small to large, the thirtieth p...
