PURPOSE: A system for automatically controlling a fountain is provided to reduce control devices for controlling a fountain and the number of power cables connected between fountain equipments, and to wirelessly transceive a control signal, thereby preventing a wrong operation caused by an inductive magnetic field while installing a fountain system. CONSTITUTION: A fountain automatic control system(1) comprises as follows. A main control device(4) transmits a digital signal to a sub control device(2) installed in a remote place through a communication cable(3), and transmits data to a sub memory circuit of the sub control device(2). The sub control device(2) receives the digital signal, arranges the data in the sub memory circuit, and controls each fountain equipment(5). A power cable(6) supplies power to each of the fountain equipments(5) connected to the sub control device(2). A communication cable(3) transmits a command of the main control device(4) to the sub control device(2), and inputs each command of the fountain equipments(5) connected to the first line of the power cable(6) to the memory circuit of the sub control device(2).
