1 is a schematic diagram of a fully automatic assembly system according to an embodiment of the present invention.

As shown in FIG. 1, the fully automatic installation system is largely comprised of the measurement part 3, the water storage part 5, the automatic valve part 7, and the discharge part 9 centering on the center control part 1. As shown in FIG. The measurement part 3 is provided in multiple numbers in the ski resort location. For example, a ski resort is a course for high-level, intermediate and beginners, and is usually divided into three sections according to the height and slope of the terrain, and the measurement unit 3 may be installed in each of these parts. Here, the measurement unit 3 measures the air temperature, relative humidity, air pressure, wind speed or wind direction as weather data, and transmits the measured data to the central control unit 1.

The central control unit 1 receives the weather data transmitted from the measuring unit 3. That is, the central control unit 1 records and analyzes data related to temperature, relative humidity, and air pressure among the meteorological data transmitted from the measurement unit 3, and then operates a predetermined program to prepare air and water for performance of the nozzle for snowmaking. Determine the mixing ratio. The automatic valve portion 7 connected to the nozzle is controlled to suit this determined mixing ratio.

As the automatic valve part 7 shows its main structure in FIG. 4, its actuator is controlled by the pneumatic system. The automatic valve portion 7 of the present invention is a water quantity control numatic valve 68, air volume control numatic valve 70, manual water hydrant 72, valves 74, 76, drain port 78, check It is composed of a valve 80 and an air subconducting pipe 82, the water volume control numatic valve 68 and the air volume control numatic valve 70 is continuously controlled according to the mixing ratio of air and water determined from the central control unit (1) It automatically adjusts the flow rate of water and air. As such, the adoption of the nomatic valve in the present invention is because it is difficult to control the flow rate immediately and continuously by the conventional motor control method. For example, the motor control method can only mechanically control stepping when a certain range of weather change is set in advance and the range is exceeded, so that it is almost impossible to mechanically control the flow rate according to the constantly changing weather conditions. In addition, such mechanical control degrades the quality of the eyes and can cause many failures. In addition, the automatic valve of the present invention shown in Figure 4 is the hydraulic pressure and air pressure of the pipe is checked and transmitted to the central control unit 1, the central control unit 1 when the pressure of a predetermined value or more drain 78 installed in the pipe The excess water in the pipe is discharged to the outside. Reference numeral 72 denotes a manual water hydrant, which is provided between the water regulating numatic valves and is configured to be manually operated in the event of a failure of the numatic valves.

Meanwhile, although one automatic valve unit 7 is illustrated in FIG. 1, a plurality of automatic valve units 7 are provided for each course as described in FIG. 2, and each automatic valve unit 7 has its own specific ID. Therefore, it is individually controlled by the central control unit 1. Therefore, the central control part 1 opens and closes the automatic valve part 7 individually.

When the inflow amount of water by the mixing ratio of water and air is determined from the central control unit 1, water is introduced from the reservoir 5 through the pipe by the corresponding flow rate. The reservoir 5 may be groundwater and a water tank in which a gauge 21 for measuring the height of water is installed. The data measured by the gauge of the reservoir 5 is of course transmitted to the central control 1.

The discharge part 9 serves to maintain a constant pressure of the pipe by discharging the excess air and water remaining in the pipe to the outside. The discharge unit 9 is also provided with a gauge for detecting the discharge rate, the data relating to the discharge of water and air is transmitted to the central control unit (1).

Here, data on nozzle performance refers to performance curves that show the inherent performance of the most important nozzles that determine system construction and eye quality. This performance curve shows the flow rate and ratio of water and air required by the nozzle for each temperature. The smaller the air demand, the better the nozzle. In addition, the initial snowfall demand means the amount of snow determined by how much snow is deposited on the slopes at the beginning of the winter season, and by how long.

Subsequently, the maximum flow rates of air and water in accordance with the input nozzle performance and the initial establishment requirement are calculated. For example, although not shown in FIG. 3, the capacity of the air compressor and water pump per m ³ / hour, the mixing ratio of air and water, and the maximum nozzle running quantity are determined. Once these data are determined by these programs, the specifications and number of each device are determined accordingly. For example, the optimal air compression force determined by the simulation of the present invention is 150 psi (10.3 bar). It has a higher compression ratio than the conventional 100 psi, which increases the efficiency of snow manufacturing. The machine room, attached machinery, system network, piping, automatic valves and control program are installed in accordance with the determined specifications.
