The invention relates to the technical field of ship equipment fault diagnosis and test, in particular to a ship rotating machinery axis track test and state evaluation method and system. The invention provides a set of rotating machinery axis track test and state evaluation system, four laser displacement sensors are adopted to collect axis variation displacement from two mutually perpendicular directions, and two sensors are designed to be standby for each other in the same direction, so that the reliability of data collection is improved; a small ferromagnetic block is pasted on the rotating shaft, and a magnetoelectric sensor is used for positioning in the circumferential direction, so that errors caused by angular displacement are eliminated, and the accuracy of data measurement is improved; an abnormal data identification processing method based on combination of a threshold value method and an interval estimation theory is provided; a dual-computer hot standby acquisition design method is provided, and
