Method for establishing a ship monitoring network based on magnetic-field communication

A method for establishing a ship monitoring network based on magnetic-field communication, the method comprising:

• a signal generation step in which at least one sensor installed in each of a plurality of compartments of a ship senses an environment and a state within the corresponding compartment and generates a signal including sensing data;
• a signal reception step in which a multi-access access point (AP) installed in each of the compartments receives the signal generated from the sensor installed in the same compartment;
• an AP-to-AP signal transmission and reception step in which a plurality of multi-access APs respectively installed in the compartments mutually transmit and receive signals using a magnetic-field communication scheme;
• a monitoring-system connection step in which at least one of the plurality of multi-access APs is connected to a central monitoring system of the ship through a wired network;
• and
• a monitoring step in which the central monitoring system analyzes signals transmitted from all of the sensors installed in the ship and monitors a state of the ship in real time.
