Ship communication signal quality detection method capable of performing detection automatically

The invention relates to the technical field of signal quality monitoring. The invention relates to a ship communication signal quality detection method for automatic detection. The method comprises the following steps: S1, determining a navigation route of a ship, collecting position information of the ship, and judging whether the ship sails on a safe route or not; according to the invention, the interval of periods is changed according to weather conditions in a route, inspection is carried out according to a normal period when the ship sails in a normal sea area, the inspection period is changed according to the degree of influence of severe weather on ship communication signal quality in a sea area with severe weather, and an inertial navigation system is started before the ship sails to the sea area with severe weather; the ship is positioned according to the previous positioning information and the ship route information, the phenomenon that the navigation system loses effect when the ship loses contac
