Fall detection method, corresponding system and machine
The present invention relates to a fall detection method, corresponding system and machine, for detecting the fall of a wear element (1) provided with a three-axis accelerometer (3) of an earth moving machine (2) with the following steps: - obtaining an accelerometer measurement (100) of each wear element (1); - determining a rotational position measurement (102) of each wear element (1) with respect to the reference axis (4) based on its accelerometer measurement (100); - determining a mean reference value (103) based on all the rotational position measurements (102); - determining a deviation value (104) of each wear element (1) based on the deviation between its rotational position measurement (102) with respect to the mean reference value (103); - determining that there is a fall of a wear element (1) if its deviation value (104) exceeds a threshold value (105); and - repeating the steps in an iterative manner.
