PURPOSE: A full-automatic snow-making system is provided to make artificial snow through automatic control without needing additional manpower for making snow in a skiing ground. CONSTITUTION: A central control unit(2) of a full-automatic snow-making system consists of a PCC(Processor Controller,4), a UPS(Uninterruptible Power Supply,6), a monitor(8), a CPU(Central Processing Unit,11), a printer(10) and an air flow indicator(12). The PCC monitors and transmits the running conditions such as flow of water and air, pressure and temperature to the CPU from each gauge. The air flow indicator displays the measured value from an air flow measurer(20). A TE(Terminal Enclosure,14) is a central concentrated wire panel of a communication wire for managing plural wires(56,58,60,62,64,66) connected with each snow-making unit. Each snow-making unit is connected to the central control unit via the TE to be controlled by the central control unit. Plural automatic valves(36,38,40,42,44) are connected with the central control unit through the wire(64,66). The valves are automatically controlled to make artificial snow through nozzles at a proper mixing ratio of water to air. The central control unit controls the amount of water and air repeatedly by receiving the result of the valves. Thereby, artificial snow is made efficiently.
