Method device and system for detecting vibration of arm rest of engineering machinery and engineering machinery

摘要

Disclosed is a method for detecting the vibration of an arm rest of engineering machinery. The method comprises: reading a rotation angle of an arm rest in a horizontal plane and a rotation angle of the arm rest in a vertical plane at multiple points of time (S102); calculating three dimensional coordinates of an end portion of the arm rest at each point of time according to the length of the arm rest and the rotation angle in the horizontal plane and the rotation angle in the vertical plane read at each point of time (S104); obtaining according to the three dimensional coordinates at each point of time obtained through calculation a condition of the three dimensional coordinates changing with time (S106). The method conveniently detects the vibration of an arm rest in different gestures in three dimensional directions is more intelligent and automatic avoids the work of manually recording the coordinates of the end portion of the arm rest and obtains a more accurate detection result. Also disclosed are a device and a system for detecting the vibration of an arm rest of engineering machinery by using the foregoing method and engineering machinery comprising the system.
