Automatic drilling system and method of ocean engineering drilling ship

The invention provides an automatic drilling system and method of an ocean engineering drilling ship, and belongs to the technical field of automatic drilling of drilling ships. Comprising a drilling machine parameter output control module, an air compressor parameter control module, a lifting control module, a current control module, a drill rod sleeve dismounting and mounting module, a data processing and control unit, a plurality of sea wave prediction devices, a wireless communication module, a wind speed measurement module, a water level detection device, a seabed geology detection module and a parameter setting module. The sea wave data prediction device is arranged to detect sea wave data in real time in advance, then the time point when each sea wave arrives at the drilling machine ship is converted according to the specific distance and speed, and then when the drilling machine is controlled to work, the allowance is controlled to correspondingly influence the sea waves, so that the real-time perform
