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