Aiming at the problems of vibratory pile driver operator's obstructed vision and difficulty in monitoring pile posture and real-time monitoring of pile driver's operating conditions,etc,a posture and working condition monitoring system of pile machine was proposed based on digital twin technology.An early warning model of pile posture skew was established to reflect the current state.By an-alyzing the early warning model,the pile posture skew warning and adjustment suggestion were realized.At the same time,the monitoring system includes the working condition detection module of the pile machine,the posture detection module of the pile body and the virtu-al model driving module,which can realize real-time collection and transmission of operating data of the pile driver,and a 3D dynamic interface is established.The blocked vision problem of the traditional pile driving is solved,and the precision and efficiency of the pile driver are improved.
