PURPOSE: An irrigation system is provided to automatically operate the irrigation for a crop cultivating facility based on the humidity of the soil inside the facility. CONSTITUTION: Plural vibration valve modules (200,210) are installed on corresponding irrigation pipe among the irrigation pipes installed on plural crop cultivation facilities. A cable module (300) connects the vibration valve modules in parallel. A control module (100) generates DC voltage and a first control signal in a predetermined level for controlling the opening and closing of the vibration valve modules based on an AC voltage received through a power line. A pair of first cables applies DC voltage to the vibration valve modules. A pair of second cables (300A) applies the first control signal to the vibration valve modules. The second cables are control lines based on a controller area network (CAN) communications method.
