Method for applying multifunctional terminal module to marine main engine protection system

The invention discloses a method for applying a multifunctional terminal module to a marine main engine protection system. In the marine main engine protection system, input and output signal interaction is carried out between a customized multifunctional terminal module and a marine main engine; the multifunctional terminal module comprises an integrated terminal unit and a controller connected with the integrated terminal unit, and the terminal unit is provided with I/O ports with the number matched with the number of monitored signals of a marine main engine; the terminal unit is used for sending a monitoring signal collected from a marine main engine to the controller, and the controller is used for processing the monitoring signal and outputting a processing result to the terminal unit. The customized integrated terminal units are adopted to form the multifunctional terminal module for the marine main engine protection system, the number of I/O ports of the terminal units is consistent with the actual po
