摘要： The present invention provides a communication recovery method using an isolator in a communication system through a power line of land and marine equipment, wherein the method promptly senses situations, such as a disconnection or a short-circuit of a communication line, and restores the communication line for sensing and warning fire or gas in a larger sized space such as an inside/outside of a ship and an inside/outside of a plant or a building.
