  ADVANTAGE OF THE INVENTION According to this invention, the irrigation system for greening which functions as a irrigation system for greening at normal time, and can rescue a human life when a fire occurs in a building can be provided.

The block diagram which shows one Embodiment of the irrigation system for greening of this invention

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows an embodiment when the irrigation system for greening of the present invention is installed on the roof of a building.

  In this embodiment, the cultivation base 1 of the irrigation system for greening is installed on the roof of the building, and water from the irrigation water source 3 is supplied to the plants (not shown) planted in the soil part 2 in the cultivation base 1. The plants are cultivated by irrigating from the irrigation means 4 such as a nozzle.

  More specifically, the growth substrate 1 may be any substrate as long as it can partition an area for growing plants, and may be formed in a box shape, for example. For example, a metal plate such as a thin steel plate may be laid on the bottom of the box-shaped growth base 1 so that moisture does not unnecessarily escape to the outside.

  A soil portion 2 for growing plants is provided in the growth base 1. Although not shown in detail, the soil portion 2 may be selected according to a plant to be cultivated from a known configuration as long as it can give an appropriate nutrient and moisture to the plant and support its growth.

  In the present embodiment, the irrigation water source 3 includes a tap water tank 3a for storing tap water and a rainwater tank 3b for storing rainwater. Both tanks 3a and 3b are preferably installed at high places in order to be used as emergency water in the event of a fire. In addition, tap water may be supplied directly without passing through the tap water tank 3a in normal times. Water from the irrigation water source 3 is forcibly supplied to the irrigation means 4 through a water passage 6 by a water supply pump.

  The irrigation means 4 in the present embodiment is formed so as to irrigate downward toward the vegetation from the nozzle groups 5a, 5b, and 5c connected to the headers 4a, 4b, and 4c in one or a plurality of groups, in this embodiment. ing. As the irrigation means 4, other known methods such as a sprinkler method and a fountain method may be appropriately employed.

  The water passage 6 is branched into three branch paths 6a, 6b, and 6c along the way, and solenoid valves on / off valves 7a, 7b, and 7c that control the amount of water flow are connected to the branch paths 6a, 6b, and 6c, respectively. Yes. Each on-off valve 7a, 7b, 7c is controlled to open and close by a controller 9 as a control means described later. Further, in the middle of the water passage 6, water supply pumps 14a, 14b, and 14c, which are means for forcibly supplying water, are installed. As shown in FIG. 1, it is desirable that there are a plurality of water branch paths 6a, 6b, 6c from the irrigation water source 3 to the irrigation means 4. If the number of irrigation means 4 is too large, it is necessary to increase the water supply capability with one water supply pump, and if the water supply pump fails, the irrigation capability is reduced. In addition, the amount of irrigation varies depending on the shape or size of the water path, and the conditions such as the irrigation location, making it difficult to control the irrigation amount. For this reason, since the several water pump 14a, 14b, 14c is installed, it is not necessary to enlarge the supply capacity of one water pump. In addition, at each position of the moisture sensor 8a, the moisture sensor 8b, and the moisture sensor 8c, the irrigation time or the amount of irrigation differs depending on the type of plant and the state of the soil, and therefore the respective water branch paths 6a, 6b, 6c. By installing the water supply pumps 14a, 14b, and 14c one by one, it is possible to efficiently perform irrigation with higher accuracy. That is, if one water supply pump 14a, 14b, 14c is installed for each water path of the on-off valve 7a, on-off valve 7b, and on-off valve 7c, the degree of opening / closing of each on-off valve 7a, 7b, 7c and the pump pressure Can be controlled at the same time, so that more accurate irrigation is possible. In FIG. 1, the number of water branch paths is three. However, the number is not limited to this number, and the number of branch paths may be determined as appropriate.

  In the soil portion 2, moisture sensors 8 a, 8 b, and 8 c that detect the amount of moisture in the soil portion 2 and transmit moisture amount information to the controller 9 are installed. The installation positions of the moisture sensors 8a, 8b, and 8c are preferably positions where the moisture of the soil portion 2 can be properly detected. In the case where the growth substrate 1 is disposed at an inclination, proper moisture can be detected by installing a moisture sensor in a lower portion of the inclination.

  Further, a fire alarm 10 that transmits a fire signal to the controller 9 when a fire occurs in a building (not shown) is installed at a necessary location.

  The controller 9 serving as a control means includes a CPU that performs arithmetic processing, a memory that stores irrigation programs and various operation methods, on-off valves 7a, 7b, and 7c, water supply pumps 14a, 14b, and 14c, and moisture sensors 8a and 8b. 8c, a processing unit 11 in which an interface for transmitting and receiving signals to and from the fire alarm device 10 and the like is incorporated, and a battery 13 including a solar power generator 12. The processing unit 11 of the controller 9 controls the opening / closing degree of each on-off valve 7a, 7b, 7c according to the amount of water information sent from each of the moisture sensors 8a, 8b, 8c in normal times, 14b and 14c are operated to send a command for irrigating an appropriate amount of water from the nozzle groups 5a, 5b and 5c of the irrigation means 4, and in the event of a fire, each fire valve 10a receives a fire signal from the fire alarm device 10; 7b and 7c are opened, and the water supply pumps 14a, 14b and 14c are operated to send a command to forcibly irrigate water from the nozzle groups 5a, 5b and 5c of the irrigation means.

  As the irrigation program executed by the processing unit 11, for example, the irrigation amount, the irrigation frequency, the limit of one irrigation amount, etc. may be appropriately set according to the type and size of the vegetation to be cultivated. In addition, the irrigation program may be configured to send a command to forcibly stop if any failure occurs. In addition to automatic irrigation, for example, a trial operation switch may be installed so that irrigation can be performed manually.

  Next, the operation of this embodiment will be described.

  In the irrigation system for greening of this embodiment, for example, by pulling out a system start switch (for example, an insulation tag, not shown) installed in the controller 9, energization of the entire system is started and the system starts operating.

  In the present embodiment, in a normal state, according to a command transmitted from the processing unit 11 of the controller 9 serving as a control unit according to the moisture content information of the soil portion 2 in the growth base 1 detected by the moisture sensors 8a, 8b, and 8c. Then, the water supply pumps 14a, 14b, 14c are operated, the opening amounts of the on-off valves 7a, 7b, 7c are controlled, and an appropriate amount of water is guided from the irrigation water source 3 to the irrigation means 4, and the nozzle groups 5a, 5b Water is sprayed from 5c and watered, and plants are cultivated properly. In this case, the on-off valves 7a, 7b, and 7c open and close independently, and the water supply pumps 14a, 14b, and 14c can be operated and stopped according to the opening and closing of the corresponding on-off valves 7a, 7b, and 7c. For example, as shown in FIG. 1, information indicating that irrigation is necessary is transmitted from the moisture sensor 8a, processed by the processing unit 11 of the controller 9, and the processing unit 11 issues a command to open the on-off valve 7a. The water supply pump 14a forcibly supplies water, and the water guided to the irrigation means 4a is sprinkled from the nozzle part 5a and irrigated to the plants. When the moisture sensor 8a senses that the amount of moisture in the soil has become appropriate during irrigation, the command is sent to the controller 9, and the processing unit 11 instructs the on-off valve 7a to be closed. The pump 14a is stopped.

  Similarly, information indicating that irrigation is necessary is transmitted from the moisture sensor 8b, processed by the processing unit 11 of the controller 9, and the processing unit 11 issues a command to open the on-off valve 7b. Water is supplied to the irrigation means 4b, and the water is sprayed from the nozzle portion 5b and irrigated to the plants. When the moisture sensor 8b senses that the amount of moisture in the soil has become appropriate during irrigation, the command is sent to the controller 9, and the processing unit 11 instructs to close the on-off valve 7b. The pump 14a is stopped.

  Further, information indicating that irrigation is necessary is transmitted from the moisture sensor 8c and processed by the processing unit 11 of the controller 9. The processing unit 11 issues a command to open the on-off valve 7c, and the water supply pump 14c is forcibly associated therewith. The water guided to the irrigation means 4c is sprinkled from the nozzle portion 5c and irrigated to the vegetation. When the moisture sensor 8c senses that the amount of moisture in the soil has become appropriate during irrigation, the command is sent to the controller 9, and the processing unit 11 instructs to close the on-off valve 7c, and water is supplied. The pump 14c is stopped.

  Through such a series of steps, vegetation can be automatically and properly grown.

  In the unlikely event that a fire occurs in a building, the processing unit 11 of the controller 9 serving as a control means receives the fire signal emitted from the fire alarm 10 and issues a command to open the on-off valves 7a, 7b, 7c for water transmission The pumps 14a, 14b and 14c are operated to forcibly irrigate water from the nozzle groups 5a, 5b and 5c of the irrigation means 4. As a result, in the event of a fire, it is possible to save lives from the fire by evacuating to the place where the irrigation system for greening is installed and irrigating the body. For example, when a building fire occurs, it is said that the average time from fire report to arrival at the fire site is about 10 minutes or less. By waiting for the body to be irrigated by the irrigation system for greening, human life is surely saved.

  According to the present embodiment, it is possible to provide a irrigation system for greening that functions as a irrigation system for greening during normal times and can save lives when a fire occurs in a building.

  In addition, this invention is not limited only to the said embodiment, It can change as needed. For example, you may install the raising base | substrate 1 in floors other than the rooftop of a building.
