Abstract

PURPOSE:To enable regulation of a water sprinkling range by selectively control ling pressure control valves, solenoid opening and closing valves, link valves, etc., according to a change in measured values of lawn growth environment data and measured values of hydraulic pressure in a water sprinkler for lawn having a controller for the amount of sprinkled water of a sprinkler. CONSTITUTION:Water from water feed pipes is sprinkled through main branch pipes (36a) to (36g) over lawn surface such as a golf course with sprinklers. In this case, when a main branch pipe (36f) is fed with water through link valves (45c), (45d), (45l) and (45g) and a link valve (45i) is closed, a water sprin kling controller senses an insufficient hydraulic pressure of the main branch pipe (36f) and judges that the insufficient hydraulic pressure cannot be eliminated by regulating opening degree of a solenoid opening and closing valve 41 and the link valves (45c), (45d), (45l) and (45g). The link valve (45i) is then opened to feed water from both ends of the main branch pipe (36f) to control the hydrau lic pressure and eliminate water deficiency.

The present applicant disclosed a lawn growing environment control device in Japanese Patent Application No. 1-177053. This apparatus will be briefly described with reference to FIG. 1 to the extent necessary for explaining the invention. The specifications of the growth environment of the lawn 20, that is, the physical quantities, chemical quantities, and other changing quantities of the atmosphere, soil, grass, etc., are measured using an appropriate measuring device. For example, a soil thermometer 1, soil moisture meter 2, hydrogen ion concentration pH meter 3, soil resistance meter 4, etc. are used to measure the soil condition, and a colorimeter 6, chlorophyll meter is used to determine the dpj condition of the lawn. A total of 7, a radiation thermometer 8, etc. are used to measure atmospheric and meteorological conditions, including a pyranometer 9, a thermometer 10, and a hygrometer 11. A rain gauge 12, a wind direction and speed gauge 13, etc. are used. These measuring instruments generate measured value signals and transmit them to the sprinkler control device 27. Watering the lawn 20 is carried out from the watering pump 29 to the flow meter 3.
This is done by supplying water to sprinkler 38 through 0. The watering control device 27 performs watering control by controlling the watering pump 29 via the controller 28 in response to changes in the environment represented by the measured value signal.

In conventional lawn watering systems, the water supply network is simple, and the equipment allows some water supply pipes to be selectively and manually shut off in an emergency situation such as a pipe being damaged. This is insufficient for detailed water supply control, such as increasing the amount of water supplied to areas that require a large amount of water, or adjusting water pressure according to the amount of water supplied. It was not possible to control the watering. Also, as shown in Figure 4A, adjacent sprinklers 38a and 38b
. If the watering ranges 50a, 50b, and 50c of 38c partially overlap to create an overlapping area 51, not only will the amount of watering be uneven, but there will also be excess water in the overlapping area 51, making it difficult to maintain an accurate lawn growth environment. cannot be controlled. With conventional lawn watering devices, it is difficult to eliminate this uneven watering effect when watering over a wide area. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a lawn watering device in which the watering range of the sprinkler is adjustable.

[Function] First, it will be explained that the water pressure of each main branch pipe 36 can be controlled. In the embodiment of FIG. 2, for example, the main branch pipe 36f
However, when the interconnection valve 45i, which receives water through the interconnection valves 45c, 45d, and 451. Detecting the lack of water pressure in the main branch pipe 36f through the electromagnetic on-off valve 41 and interconnection valves 45c, 45d, 451.
When it is determined that the water pressure shortage cannot be resolved by adjusting the opening of the main branch pipe 45j, the water pressure can be controlled by opening the interconnection valve 45i and supplying water from both ends of the main branch pipe 36f to eliminate the water pressure shortage. If the water pressure in the main branch pipe 36 can be maintained at the required level,
The size of the spray area 50 (eg 50a in FIG. 4A) of each sprinkler 38 can be properly controlled according to design by adjusting the pressure control valve 47 from the sprinkler control device 27. When the sprinkler ranges 50 of the sprinklers 38 partially overlap as shown in FIG. 4A, the undulation angle control unit 60
The watering range control unit 62 operates effectively. 4th A
The watering range 50a of the sprinkler 38a shown in the figure is fan-shaped like the watering range 50a of Fig. 4B, and the sprinkler 38a
If the sprinkler 38c is made into a shape close to a fan shape like the watering range 50b in Fig. 4B, and the sprinkler 38c is made into an uneven shape like the watering range 50c in Fig. 4B, then
The overlapping part 51 in the figure disappears. The principle of one embodiment of the rotation range control unit 62 will be explained with reference to FIG. The rotation range control unit 6 is controlled by a pulse motor M (Fig. 1) and an encoder E (Fig. 1).
2, and the sprinkler 38 is rotated by the shaft 65 of the motor M by a known transmission mechanism (not shown). The illustrated encoder E has a perforated rotating plate 66 attached to a shaft 65 at right angles, and light from a light emitting diode 68 is passed through a slit 6.
At 9, point the photodiode 7o toward the hole 67 of the rotating plate 66.
detects the light transmitted through the rotating plate 66. Hole 67 of rotating plate 66
The holes 67 are drilled along a plurality of tracks, and the size and arrangement of the holes 67 differ from track to track, for example, as shown in the diagram on the right side of FIG. In this case, the angular position of the shaft 65 can be detected with an accuracy of 22.5 (36072') degrees using four tracks. Increasing the number of tracks to increase detection accuracy is a technique well known to those skilled in the art. The encoder E detects that the angular position of the shaft 65 of the pulse motor M is separated from the reference direction 55 by the starting position angle B (FIG. 4B), and the sprinkler 38 is activated by a transmission mechanism (not shown). The encoder E detects that the angular position of the shaft 65 of the pulse motor M is separated from the starting position angle B by the rotation range S, and the transmission mechanism starts the rotation of the sprinkler 3.
If the rotation of 8 is stopped, the water sprinkling range 50a shown in FIG. 4B can be obtained provided that an appropriate water pressure is applied. Watering range 5 of sprinkler 38b shown in Figure 4B
0b controls its rotation range in the same manner as the above-mentioned watering range 50a, and also controls the undulation angle H (Fig. 1) of the sprinkler 38 so that a radial arc edge of the watering range 50b is generated. 60. The heave angle control uni-soto 60 connects the shaft 65 of the pulse motor M shown in FIG.
The angular position of the shaft 65 is monitored and controlled by the encoder E. The change in the undulation angle H of the sprinkler 38 for producing the radial arc edge of the water sprinkling area 50b can be stored in the water sprinkling control device 27 after being determined experimentally. The irregular water spraying range 50c of the sprinkler 38c can be obtained by appropriately controlling the undulation angle I]. Changes in the undulation angle H of the sprinkler 38c, which causes the complicated edge shape of the water sprinkling range 50c, can also be stored in the water sprinkling control device 27 after being determined experimentally. Thus, the object of the present invention to provide a lawn watering device in which the watering range of the sprinkler is adjustable is achieved.
