The invention discloses a computer program product for early fault early-warning and analysis of a rotation type machine. The computer program product comprises a state learning part and a state monitoring part. According to the state learning part, a self-learning machine feature parameter way is employed; after completion of self-learning of the system, switching to a monitoring state is carried out automatically and then the machine is monitored in real time. According to the invention, the computer program product has functions of long-term real-time on-line monitoring and analyses. The micro abnormal impact energy can be captured and faults like tooth surface pitting, bearing rolling body fatigue stripping, excessive engine piston ring wearing, and crank shaft sliding bearing scratching and the like can be found; and severe high-energy faults like tooth breaking and shaft breaking and the like can also be monitored in real time; and then shutdown of the machine can be carried out immediately to prevent deep destruction. Therefore, the machine faults can be monitored in real time and can be analyzed timely; and fault positions and possible fault modes can be pointed out and thus the maintenance staff can carry out fault elimination and repairing conveniently.
