Marine multi-interface magnetic starting system and control method thereof

The invention relates to a marine multi-interface magnetic starting system. The system comprises a magnetic starter, the primary side of a transformer on the magnetic starter takes electricity from a three-phase main circuit, the secondary side of the transformer supplies power to a control loop of the magnetic starter, one end of the three-phase main circuit is connected with a power source, the other end is connected with a motor, a manual stop switch, an automatic stop switch, an automatic starting branch circuit and a contactor are sequentially connected to the control loop in series, the contactor controls connection of a main contact of the contactor, and connection of the automatic stop switch and the automatic starting branch circuit is controlled by an automatic control system. The system is provided with local and remote manual start-stop interfaces and automatic start-stop interfaces, the number of the interfaces is easy to expand, standardized design of the magnetic starter is facilitated, the mag
