Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention uses a plurality of snowfall machines,
The present invention relates to a radio control control artificial snowfall device for controlling the snowfall machine by radio control.

[0002]

2. Description of the Related Art Recently, many ski resorts are equipped with artificial snowfall facilities in order to secure snow in preparation for a warm winter.
There are also ski areas in the Tokyo metropolitan area that operate only by artificial snowfall.

For example, referring to FIG. 3, the artificial snowfall facility
Water pipe 1 connected to a water pump 11 provided in a reservoir 10
2, a plurality of nozzles 13 are provided, and air is supplied from an air compressor 14 to the nozzles 13 through an air pipe 15 to mix water and air. Snow is sprayed in the air inside the slope 16 in a jet state. As shown in FIG. 4, the snow blower 9 has an air gun 8 that is a nozzle that mixes and jets air and water, and the air gun 8 passes through valves that control the amounts of water and air, respectively. As it is connected, the height and angle are adjusted.

Further, as the snow gun, for example, the snow gun described in JP-A-6-74627 can be used.

[0005] And, this snowmaking work usually goes to the slope when the slope is off at night, and the snow condition, the condition,
In addition, the amount of water and air sprayed, the nozzle angle and snowfall time are determined in consideration of weather conditions such as temperature, wind speed, wind direction, and temperature, and the valve opening and nozzle angle of the snowfall machine are adjusted. The workers went to the site and performed the work manually.

[0006]

However, in general, snow machines are inconveniently located on the side of the slopes, the scaffolding is not well maintained, and it is often laborious to approach them. Even during the same night, some time elapses. Then, the work environment is extremely bad, such as shifting the snow-covered slope and adjusting the snowfall machine again. Moreover, since the snow machines are installed on the slopes at a pitch of 40 to 50 m, and there are more than 30 skis per ski resort
Work under poor conditions.

[0007] Further, a fully automatic operation artificial snowfall device provided with a central control room takes up a lot of space and costs much.

Therefore, it is an object of the present invention to provide a radio control-controlled artificial snowfall device which can adjust the snowfall machine without approaching the snowfall machine, has a simple structure, and is inexpensive.

[0009]

According to the present invention, in a radio control control artificial snowfall device which uses a plurality of snowfall machines and controls the snowfall machines by radio control, the snowfall machine is provided with a receiver, The receiver is provided with a unique identification number, and the receiver operates only when it receives said unique identification number.

Further, according to the present invention, the unique identification number uses a plurality of contacts, and the identification number is set by a combination of the contacts.

[0011]

The present invention is configured as described above. When a radio control transmitter sends a signal for controlling a snowfall machine, the receiver provided in the snowfall machine receives the signal. Drive the nozzle with the motor to the specified angle.

Further, a receiver provided in the snowfall machine is provided with a unique identification number (hereinafter referred to as an ID number).
Since the receiver works only when the D numbers match, another snowfall machine does not work together.

Therefore, if the person in charge goes to the slope to judge the condition, and the radio control transmitter designates the ID number and instructs the control items to be transmitted, the respective snow machines operate according to the instructions. Since the snowfall machine is identified by the ID number and the ID number is formed by combining a plurality of contacts, it is not necessary to assign a frequency to each snowfall machine, and the transmitter can be made compact.

[0014]

Embodiments of the present invention will be described below with reference to the drawings.

In the drawings, members having the same function are designated by the same reference numerals, and description thereof is omitted.

FIG. 1 is a diagram showing the entire construction of a radio control-controlled artificial snowfall device according to the present invention. In a snowfall machine 9, a snowgun support portion 2 is provided on an upper portion of a main body 1 so as to be slidable up and down, and the support portion 2 thereof is provided. A snow gun 8 is swingably attached to the upper end of the snow gun 8 and driving motors 2a and 3 are provided respectively, so that the snow gun 8 can change a horizontal rotation angle α and a vertical injection angle β. Has become.

As the snow gun 8, for example, the one described in Japanese Patent Laid-Open No. 6-74627 can be used.

A water circuit 12a is connected to the water pipe 12 via a valve 5 having a drive motor 5a, and an air circuit 15a is connected to the air pipe 15 via a valve 6 having a drive motor 6a. It is connected to the snow gun 8.

The motors 5a, 6a, 2a,
Each of the control panels 3 is connected to a control panel 7, and the control panel 7 drives the above-mentioned motor by a signal from a radio control receiver (not shown) incorporated therein to open and close the water valve and the air valve, rotate the left and right air guns, Pre-determined ID as well as increasing and decreasing the vertical injection angle
It is configured to work only when a number is received.

FIG. 2 shows a block diagram of the transmitter 28, which has a snowfall machine ID number designation section 29 and a snowfall machine control section 30.

Then, in the illustrated example, the snowfall machine ID number designating section 29 uses five contact points, as shown in Table 1, 00
It is configured to be able to identify 32 kinds of 001 to 11111 that can be identified. Therefore, 32 snow machines can be controlled.

[0022] Further, the snowfall machine control unit 30 is configured to be able to control eight points of opening / closing of a water valve, opening / closing of an air valve, up / down of an air gun, and increasing / decreasing an angle of the air gun.

The ID number may be determined by selecting the number of contacts according to the number of snowfall machines, and is not limited to the above five contacts.

The operation will be described below.

First, a person 29 in charge of operating the snow machine 9 specifies the ID number of the snow machine to be operated by the snow machine ID number specifying section 29 of the transmitter 28, and then the control section 30 controls the water and air valves and If the transmitter issues an instruction for the left-right angle and the vertical angle of the air gun 18 through the transmitter, the receiver having the instructed ID number starts operating, drives the instructed motor through the control panel, and starts snowmaking. .

In the same way, give instructions to the necessary snow machines,
If you start and stop the snow machines, you can operate many snow machines at one place.

[0027]

Since the present invention is constructed as described above, it has the following excellent effects.

(1) After going to the slope to judge the situation, after that, a large number of snow machines can be operated by radio control control from a place with a good working environment. (2) A large number of snow machines can be controlled with one frequency by ID numbers, and the transmitter can be made small and inexpensive. (3) The situation judgment requires manpower, but it is more cost-effective than full-automatic operation from the main control room, and there are no practical problems. (4) Therefore, the artificial snowfall device can be operated with a simple facility and a work environment with a small number of man-hours.
