PROBLEM TO BE SOLVED: To provide a work machine capable of accurately detecting plural kinds of abnormal states in which shock generation directions are different respectively.SOLUTION: An acceleration sensor 44 mounted on a work machine can detect independently, acceleration of a first direction (for example, an X-axis direction) and acceleration of a second direction (for example, a Y-axis direction) different from the first direction. The acceleration sensor 44 outputs a first detection signal according to a detection result of the acceleration of the first direction, and a second detection signal according to a detection result of the acceleration of the second direction. Then, it is determined whether or not at least a first event has occurred out of plural kinds of events that occur on the work machine, based on the first detection signal. Then, it is determined whether or not at least a second event different from the first event has occurred out of the plural kinds of events, based on the second detection signal.SELECTED DRAWING: Figure 5 |
