Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an automatic water supply system that automatically supplies water to a water supply target such as soil in a planting facility such as a flower pot or a plant mat.
[0002]
[Prior art]
Conventionally, as a technique related to supplying water to a water supply target such as soil in a planting facility such as a flower pot or a planting mat, the content of moisture in the soil is opposed to, for example, Japanese Utility Model Laid-Open No. 2-17054. There is a flower pot provided with a lamp or buzzer that detects the resistance between electrodes and notifies the start of water supply.
[0003]
However, when the person who supplies the water is absent for a long time, the notification by the lamp or the buzzer cannot contribute to the water supply at all. Therefore, there is a problem that the plant is withered even if the flower pot is used. Further, in the flower pot, there is no disclosure about a special water supply method and the like, and water is supplied artificially according to the notification by the notification means. There is also a problem that requires water supply work.
[0004]
In order to solve the above problems, for example, as shown in Japanese Utility Model Publication No. 62-16257, an automatic water supply system that automatically supplies water at a predetermined time interval, for example, Japanese Utility Model Publication No. 5-4862 shows Thus, the amount of moisture in the soil is detected, and a device that automatically supplies water according to the detection result, for example, as shown in Japanese Utility Model Publication No. 61-74359, a flower pot is placed in a water tank. There has been proposed an automatic water supply system or the like that detects an upper limit and a lower limit state of water in a water tank and starts water supply after a predetermined time has elapsed after the water reaches a lower limit.
[0005]
However, even in the above-mentioned automatic water supply system, no consideration is given to the state of the plant that should be used as a basis for determining whether water supply is necessary or not, and when much water is required or almost water is required. Water is supplied to all plants that do not have the same treatment by the same treatment. Therefore, for example, when the water supply treatment is set according to the time when a large amount of water is required, a large amount of water is supplied at a time when almost no water is required, and this large amount of water causes root rot. This causes the problem of withering plants. In addition, since extra water is supplied, there is a problem that water costs become enormous.
[0006]
On the contrary, when the water supply treatment is set in accordance with the time when almost no moisture is required, the water is hardly supplied at the time when a lot of water is required, resulting in a problem that the plant is withered. .
[0007]
The time when a large amount of moisture described above is required is, for example, immediately after placing cut grass or the like on the soil in a planting facility for placing cut grass or the like on the soil. Immediately after placing the cut grass on the soil, the grass roots are not familiar with the soil and are not rooted, and an air layer is formed between the grass roots and the soil. Is the weakest state. Therefore, it is a time when there is a high possibility of withering due to a lack of moisture, and a lot of moisture is required to quickly root the grass roots in the soil.
[0008]
On the other hand, the time when almost no moisture is required is, for example, after roots such as cut grass have taken root in the soil in a planting facility where cut grass is placed on the soil. After roots such as turf cut into the soil, the water absorption is strong, so it is preferable to cultivate as close to nature as possible, and root rot occurs or is poor due to excessive water supply. It is a time when there is a high possibility that the grass will grow. And in order to grow a more durable plant, it is significant to give a certain water stress, and it is not necessary to supply much water at such a time.
[0009]
Furthermore, in order to eliminate the above problems in consideration of the state of the plant, for example, there is a technique disclosed in JP-A-10-313675. This is to plant lawn seeds or early growth lawn in artificial soil, maintain the water level in the artificial soil at a high water level, and then lower the water level as the lawn root grows. .
[0010]
[Problems to be solved by the invention]
However, the technique disclosed in Japanese Patent Laid-Open No. 10-313675 does not automatically control the water level according to the state of the plant, but does not visually check the growing state of the grass roots. It is necessary to do this, and the water level is also adjusted artificially, resulting in troublesome water supply management.
[0011]
Furthermore, since artificial soil is maintained soaked in moisture at all times, the grown lawn can absorb moisture at any time, resulting in poor lawn. In addition, the water level is adjusted so that the artificial soil is always immersed in water, and it is necessary to supply water even at a time when not much water is required, resulting in a problem that water costs become expensive. .
[0012]
The present invention has been made paying attention to the above problems, and according to the state of the plant, it is possible to perform water supply management in a state as close to nature as possible efficiently and as a result, a durable plant can be obtained. It aims at providing the automatic water supply system which can be cultivated.

[0024]
[Action]
Next, the operation of the automatic water supply system of the present invention will be described.
[0025]
In the automatic water supply system of the present invention, it is possible to switch between a plurality of modes having different water supply start conditions in accordance with predetermined switching conditions, and the presence or absence of a required water amount at a moisture state detection location is detected by a sensor or the like. Detect and detect the lack of moisture such as no required moisture amount. When the lack of moisture is detected, the first mode to start water supply to the water supply target and the presence or absence of the required moisture amount are detected by the sensor, etc. In this case, a predetermined stress time is measured by the timer unit, a second mode is set in which water supply is started after the timer unit finishes the stress time measurement, and the first mode and the second mode are set according to a predetermined switching condition. The first mode is activated when a large amount of moisture is required, and the second mode is activated when not much moisture is required. It becomes possible, without having to kill the plant, surely, it is possible to grow the plant and can only close to nature state.
[0026]
As another example, the first mode in which water supply is performed every predetermined water supply interval time, such as every water supply interval time that the water supply target will not be in a dry state, and the presence or absence of the required water amount at the moisture state detection location are determined by the sensor. A determination is made based on the detection, and when it is determined that there is no required amount of water, a predetermined stress time is measured by the timer unit, and a second mode is set in which water supply is started after the timer unit finishes the stress time measurement. By adopting a configuration in which the mode and the second mode are automatically switched according to a predetermined switching condition, the first mode is activated at the time when a large amount of moisture is required, as described above, and a little moisture is required. The second mode can be activated during the period when the plant does not, and the plant can be cultivated reliably and as close to nature as possible without dying the plant.
[0027]
As another example, the water supply target may be in a dry state, for example, in a first mode in which water supply is performed every predetermined first water supply interval time such as every time interval in which the water supply target will not be in a dry state. A second mode in which water is supplied every predetermined second water supply interval time longer than the first time such as every time interval is set, and the first mode and the second mode are set according to a predetermined switching condition. By adopting a configuration that automatically switches, the first mode can be activated when much moisture is required as in the above, and the second mode can be activated when not much moisture is required, Plants can be cultivated reliably and as close to nature as possible without dying the plants. In this example, since a sensor or the like is not required, the system can be constructed at low cost.
[0028]
As another example, the presence or absence of the required water amount at the moisture state detection location is determined based on the detection of the sensor, and when a water shortage such as no required water amount is detected, the predetermined first stress time is measured by the timer unit, When the timer unit finishes the first stress time measurement and starts water supply by the water supply means, and the presence or absence of the required water amount at the moisture state detection location is determined, and when water shortage such as no required water amount is detected A second mode in which a predetermined second stress time longer than the first stress time is measured by the timer unit, and water supply by the water supply means is started after the timer unit finishes the second stress time measurement. By adopting a configuration in which the first mode and the second mode are automatically switched according to a predetermined switching condition, the first mode is activated at a time when a large amount of moisture is required, Ri is the time that do not require it is possible that the second mode operates without kill the plant, can be reliably cultivated plants and can be simply close to nature state.
[0029]
Furthermore, in the automatic water supply system of the present invention, the above-mentioned plurality of modes are laid outdoors, for example, by having a mode that does not control the water supply means to perform water supply (no water supply mode in which no water is supplied). In winter, which is a dormant season such as turf, etc., it is possible to further save water charges by executing this non-water supply mode.
[0030]
Furthermore, in the automatic water supply system of the present invention, it is possible to switch or select different modes of the moisture supply method as described above, and to set the mode itself, and to select the mode according to various conditions such as the type of plant and the installation location. The mode itself can be set, and an automatic water supply system according to the user's wishes can be obtained. For example, when the system is turned on, the switching mode stored as the initial state is executed, and only when the switching mode is not executed, the non-switching mode is selected and switching and non-switching are selected. Only when the stored non-switching mode is executed and the switching mode is executed, it is possible to select the switching mode and select switching and non-switching.
[0031]
Furthermore, by setting the switching condition of the mode switching of the present invention, for example, in the case of turf, the time or period during which the turf will take root, or the like after the predetermined time or the predetermined period has elapsed after selecting the predetermined mode, In addition to contributing to training, the system itself can be simplified and the cost can be reduced. It is preferable that the predetermined time for the switching condition can be freely set via an operation unit, a switching unit, a switching mode selection unit, etc., for example, when the switching mode is automatically executed in an initial state, By setting the time to “0”, a configuration for selecting the non-switching mode is possible.
[0032]
Furthermore, by adopting a configuration in which the execution mode is determined according to the time stored and updated in the calendar unit, it is possible to execute an appropriate water supply process according to the state of the plant.
[0033]
In addition, as a switching condition of the present invention, it is also possible to set a switching condition based on the detection of the growth state of the plant, thereby accurately grasping the state of the plant and making an appropriate water supply treatment judgment by the control means. It is possible to perform more reliable water supply management. As the detection of the state of the plant, for example, if it is a method of cultivating by placing cut grass on the soil, it is preferable to detect the rooted state of the grass. In this case, for example, a pressure sensor or the like is provided between the cut grass and the soil, or by detecting a component (weak acidity) in the soil, appropriate detection such as grasping the rooted state is possible.
[0034]
DETAILED DESCRIPTION OF THE INVENTION
Below, the automatic water supply system of this invention is demonstrated based on the specific embodiment in a figure. FIG. 1 is an overall configuration diagram showing an embodiment of an automatic water supply system of the present invention.
[0035]
The automatic water supply system of FIG. 1 is a case where it is applied to a plant cultivation unit configured by placing a plant cultivation container 20 in a water storage tray 10 capable of storing moisture, and a plant 40 is placed in the plant cultivation container 20. A growing material 30 such as soil for cultivation is filled, and a plant 40 is planted in the growing material 30. 30a is a growing material such as soil when the plant 40 such as cut grass is planted in advance, and 30b is a growing material such as soil separately filled in the plant cultivation container 20.
[0036]
The water storage tray 10 has a bottom surface 11 and a side wall 12, and the side wall 12 is formed in a substantially box shape having a low top surface and an overflow portion such as a recess provided at the height of the side wall 12 or substantially at the top of the side wall 12 (see FIG. The water content can be stored in a range in which the water level does not exceed the height of (omitted). By providing the water storage tray 10, it is possible to store a certain amount of water after water supply or when there is natural rain, so that the number of water supply can be reduced.
[0037]
The plant cultivation container 20 has a bottom surface 21 and a side wall 22 and has a substantially box shape with an open top surface in which a side wall 22 higher than the side wall 12 of the water storage tray 10 is formed. It is formed and the opening becomes wider toward the top. The bottom surface 21 is provided with leg portions 21a that support the plant cultivation container 20 downward, and is formed with water-absorbing convex portions 21b that protrude less than the leg portions 21a. A water absorption hole 21b1 is formed. Further, although not shown in the drawing, in addition to the water absorption holes 21b1 of the water absorption convex portion 21b, the excess water in the plant cultivation container 20 is drained to the water storage tray 10 and is also used to ventilate the plant cultivation container 20. A plurality of pores are formed in the bottom surface 21 or the like of the plant cultivation container 20.
[0038]
In this embodiment, the upper end 12a of the side wall 12 of the water storage tray 10 is formed lower than the height of the leg portion 21a of the plant cultivation container 20, and the bottom surface 21 of the plant cultivation container 20 placed by the leg portion 21a and the water storage tray. Even when the water surface 50 reaches the upper limit water level, the air layer 60 is always formed between the water surface 50 and the water surface 50 stored in the water 10. The air layer 60 facilitates ventilation from the water / air vent hole into the plant cultivation container 20, thereby obtaining a root rot prevention effect.
[0039]
Further, a gap 70 is formed between the top of the water absorption convex portion 21b and the bottom surface 11 of the water storage tray 10, and the water in the water storage tray 10 is transferred from the water absorption holes 21b1 formed at the top of the water absorption convex portion 21b by a capillary phenomenon. It is a structure that can absorb water into the cultivation container 20, and is a so-called bottom watering type plant cultivation unit.
[0040]
And the sensor 80 is mounted in the water storage tray 10, and it is set as the structure which can detect the presence or absence of the required moisture content in the water storage tray 10 with the sensor 80. FIG. As the sensor 80, an appropriate sensor capable of detecting the required amount of water can be used. For example, at least two electrode bodies (conductive materials) are arranged at a predetermined interval, and electric power is provided between the electrode bodies. Use a device that detects the amount of water based on the resistance value when the water flows. The sensor 80 or the sensor 80 for detecting the presence / absence of the moisture amount by the resistance value between the electrode bodies, or the control means 100 detects the absence of the predetermined moisture amount when the resistance value between the electrode bodies reaches a predetermined reference upper limit resistance value. In addition, when a predetermined reference lower limit resistance value is reached, the presence of a predetermined moisture amount is detected.
[0041]
In this embodiment, the same reference resistance value is used as the reference upper limit resistance value and the reference lower limit resistance value. For example, two upper and lower reference resistances are separately added to the reference upper limit resistance value and the reference lower limit resistance value. It is also suitable as a configuration in which water is supplied until a reference lower limit resistance value is reached after setting and using a value and detecting the absence of moisture.
[0042]
In this embodiment, the place where the sensor 80 is provided as the moisture state detection point is in the water storage tray 10, but this is used when the automatic water supply system is operated, for example, compared to the case where the sensor 80 is provided in soil or the like. This is because a moisture state detection value having high accuracy and stability can be obtained as a reference for detecting the moisture state of a plant cultivation unit or the like.
[0043]
When the sensor 80 is provided on the soil, the surface of the soil, the approximate center in the height direction, the bottom, the shaded part or the sunny part hidden in the leaves of the plant, or whether it is sunny or rainy. A considerable error often occurs depending on which part of the moisture content is detected, and it is difficult to accurately determine whether or not the moisture is insufficient. For example, the surface of the soil is easy to dry in fine weather and becomes wet when there is a small amount of rain, and the area below the center of the soil is difficult to dry even in fine weather. Since it is in a dry state, it is difficult to determine whether it is appropriate to adopt a moisture amount at any location as a reference for water supply execution. However, the automatic water supply system of the present invention includes the provision of the sensor 80 in the soil. For example, in the case of a plant cultivation container or the like that does not have a water storage tray, a configuration in which the sensor is provided in the soil is appropriately adopted. Is possible.
[0044]
Further, in the present embodiment, as the water supply means 90, a water supply pipe 91 is connected from a water source so as to be able to supply water into the water storage tray 10, and an electromagnetic valve 92 is provided in the middle of the water supply pipe 91 to supply and stop water supply by opening and closing. is doing. Note that a flow meter or the like may be added to the water supply pipe 91 as necessary. The electromagnetic valve 92 and the sensor 80 of the water supply means 90 are connected to the control means 100 via wired or wireless, respectively. The control means 100 acquires the detection information of the sensor 80, and based on this detection information, the electromagnetic valve 92 of the water supply means 90. Is configured to control water supply and water supply stop by the water supply pipe 90.
[0045]
Next, the 1st Example in the automatic water supply system of the plant cultivation unit of the said embodiment is demonstrated. 2 and 3 are system block diagrams when water supply control is performed by a timer unit or a flow meter, FIG. 4 is a flowchart showing the overall flow of water supply control processing, and FIGS. 5 and 6 are water supply control by a timer or flow meter. FIG. 7 is a time chart showing the overall flow of the first embodiment. FIG.
[0046]
In the automatic water supply system of the first embodiment, as shown in FIG. 2 or FIG. 3, the control means 100 and the sensor 80, and the control means 100 and the water supply means 90 are connected by wire or wireless via an I / F (interface). Has been. The sensor 80 includes a detection unit 81 and two electrode bodies omitted in the drawing, the detection unit 81 detects a resistance value between the two electrode bodies, and the control unit 100 determines the presence or absence of a predetermined moisture amount. In this configuration, the resistance value is sent to the CPU of the control means 100 via the I / F. Note that a sensor or the like may be provided in the sensor 80 as necessary, and the sensor 80 may have a function of determining the presence or absence of a predetermined moisture amount from the resistance value.
[0047]
The water supply means 90 includes a water supply pipe 91 and an electromagnetic valve 92, and a flow meter 93 is added as shown in FIG. 3 as necessary. The electromagnetic valve 92 and the flow meter 93 are connected to the CPU of the control means 100 via the I / F, and are configured to transmit and receive information.
[0048]
The control means 100 in the present embodiment mainly includes an operation unit 102 for performing a required operation on the CPU 101, a timer unit 103, a storage unit 104 such as a RAM or ROM for storing required items, and a display for displaying predetermined items. Unit 105, a switching mode selection unit 106 that selects a switching mode or a non-switching mode, and a switching unit 107 that performs switching of setting items and the like are provided in connection with each other, and CPU 101 is connected to each sensor via an I / F. 80 detectors 81, an electromagnetic valve 92 of the water supply means 90, and a flow meter 93 of the water supply means 90 as necessary.
[0049]
In the control means 100, the resistance value transmitted from the detection unit 81 via the I / F is input to the CPU 101, and the CPU 101 compares the input resistance value with a predetermined reference resistance value that is set and stored. The presence or absence of a predetermined amount of water is determined based on the size. The reference resistance value can be variously changed and set by the control means 100 or the sensor 80, and can be set according to the user's wish in consideration of the location of the water supply target.
[0050]
Further, based on the determination result of the presence / absence of a predetermined moisture amount, the CPU 101 of the control means 100 sends / receives a water supply start signal or a water supply stop signal to the electromagnetic valve 92 via the I / F, and opens and closes the water supply by opening the electromagnetic valve 92. Water supply by the pipe 91 is started, and water supply is stopped by closing the electromagnetic valve 92. Further, in the case of FIG. 3, the flow rate in the water supply pipe 91 can be integrated based on the measured value of the flow meter 93, and the water supply can be stopped by closing the electromagnetic valve 92 based on a predetermined integrated flow rate.
[0051]
The flow of the water supply control process by the control means 100 of the first embodiment is as shown in FIG.
[0052]
First, the automatic water supply system such as the control unit 100, the sensor 80, and the water supply unit 90 is turned on (S1), and the switching mode selection unit 106 selects the switching mode or the non-switching mode (S2). The selection configuration of the switching mode or the non-switching mode is appropriate. For example, the switching mode or the non-switching mode is selected, or the non-switching mode is selected when 0 hours is set as the predetermined time for executing the switching mode. It is possible to do so. It is determined whether the switching mode or the non-switching mode is selected by the mode selection (S3). The mode selection method varies depending on the initial state setting, etc., but when the non-switching mode is not selected, the switching mode is automatically executed, and the non-switching mode is executed only when the non-switching mode is selected. It is also possible to adopt such a configuration.
[0053]
When the switching mode is selected, the first mode is started (S4), and the timer unit 103 starts measuring a predetermined switching time (S5). The switching time is, for example, a time set as a predetermined time for executing the switching mode. Then, it is determined whether or not the switching time has ended (S6). If it is during the switching time, the comparison between the resistance value acquired by the sensor 80 and the reference resistance value set in the storage unit 104 is continuously performed. Alternatively, it is performed at predetermined time intervals, etc., and when the resistance value of the sensor 80 reaches or exceeds the reference resistance value, the absence of the required amount of moisture is detected, and when the resistance value of the sensor 80 does not reach the reference resistance value or exceeds If not, the presence of the required amount of water is detected (S7).
[0054]
If it is detected that the required water content is present, it is determined again whether the switching time has ended (S6), the presence / absence of the required water content is detected (S7), and the detection processing for the presence / absence of the required water content is switched. Do it until the time is up. On the other hand, when it is detected that there is no required amount of water, a water supply process is performed (S8). As will be described later, the water supply process is performed, for example, until a predetermined water supply time elapses or until the integrated flow rate reaches a predetermined upper limit value.
[0055]
When the predetermined switching time measured by the timer unit 103 ends (S6), the switching time is initialized (S9), and the second mode set in the storage unit 104 by the control of the CPU 101 is started (S10). In this embodiment, when it is detected that there is no required amount of water, after the water supply process is completed, it is determined again whether the measurement of the predetermined switching time has ended (S6), and while the water supply process is being executed, The determination of the end of the predetermined switching time (S6) and the detection process (S7) for the presence or absence of the required water content are stopped. Further, when the non-switching mode is selected by the mode selection and it is determined that the non-switching mode is selected (S2, S3), the second mode is started (S10).
[0056]
That is, the first mode is executed during a predetermined switching time or during a time obtained by adding the water supply time and the time until the water supply start time within the predetermined switching time. A predetermined water supply process is performed, and the determination and the water supply process are repeatedly performed during the first mode. In the first mode, it is also possible to detect the presence or absence of the required water amount by the sensor 80 even during the water supply, and stop the water supply when the presence of the required water amount is detected. It is also possible to adopt a configuration in which water supply is stopped in the middle with priority given to.
[0057]
When the second mode is started, the determination of the presence or absence of the required moisture amount is performed continuously or at predetermined intervals based on the resistance value acquired by the sensor 80 (S11). The timer unit 103 starts measuring a predetermined stress time (S12). The reference resistance value may be set as the required water amount in the second mode as a different water amount from the required water amount in the first mode.
[0058]
During the measurement of the stress time, the control unit 100 determines the presence or absence of the required water amount based on the resistance value continuously or at predetermined intervals (S13). In 103, the stress time during measurement is initialized (S14), and the process returns to the determination of the presence or absence of the required water amount (S11). This is because when a plant cultivation unit is provided outdoors, it is not preferable to switch from a moisture-free state to a moisture-containing state due to rainfall during the stress time, and it is not preferable to supply water after this switch because it is a waste of water, etc. .
[0059]
If no required water amount is detected during the stress time, it is determined whether the measurement of the stress time has ended (S15). If the measurement of the stress time has not ended, the presence / absence of the required water amount is again determined. Returning to the determination (S13), when the measurement of the stress time is completed and the state without the required water amount is maintained during the stress time, the stress time measured by the timer unit 103 is initialized (S16), and the water supply process is performed. (S17). The water supply process is performed, for example, until a predetermined water supply time elapses or until the integrated flow rate reaches a predetermined upper limit value. After the water supply process is completed, the process returns to the determination of the presence or absence of the required water amount again (S11). That is, in the second mode, when it is determined that the required water amount is absent using the sensor 80, the measurement of the stress period starts, and the water supply process is performed only when the state without the required water amount is maintained during the stress period.
[0060]
When performing the water supply process until a predetermined water supply time elapses, for example, as shown in FIG. 5, control is performed based on measurement of the predetermined water supply time by the timer unit 103. In the case of FIG. 5, the water supply start signal is output from the control means 100 to the water supply means 90 (F1), the water supply start signal is input to the electromagnetic valve 92 of the water supply means 90 (G1), and the electromagnetic valve 92 is opened. Then, water supply is started (G2). On the other hand, after the water supply start signal is output, the control unit 100 starts measuring the water supply time by the timer unit 103 (F2), and determines whether or not the measurement of the water supply time has ended until the predetermined water supply time ends ( F3) When a predetermined water supply time ends, a water supply end signal is output to the water supply means 90 (F4), and the water supply time measured by the timer unit 103 is initialized (F5). In the water supply means 90, the water supply end signal is input to the electromagnetic valve 92 (G3), and the electromagnetic valve 92 is closed to end the water supply (G4).
[0061]
Further, when the water supply process is performed until the integrated water supply amount reaches a predetermined upper limit flow rate value, for example, control is performed based on a predetermined integrated flow rate by a flow meter 93 as shown in FIG. In the case of FIG. 6, a water supply start signal is output from the control means 100 to the water supply means 90 (F11), the water supply start signal is input to the electromagnetic valve 92 of the water supply means 90 (G11), and the electromagnetic valve 92 is opened. Then, water supply is started (G12). On the other hand, the control means 100 measures and integrates the flow rate of water flowing through the water supply pipe 91 after the water supply start signal is output by the flow meter 93 (F12), and determines whether the integrated flow rate has reached a predetermined upper limit value (F13), When the predetermined upper limit value is reached, a water supply end signal is output to the water supply means 90 (F14), and the integrated flow rate value is initialized (F15). In the water supply means 90, the water supply end signal is input to the electromagnetic valve 92 (G13), and the electromagnetic valve 92 is closed to end the water supply process (G14).
[0062]
By providing the flow meter 93, the water supply amount can be controlled as a more reliable value than when the timer unit 103 is used. That is, even when the flow rate from the tap is different depending on the situation of the building and the time, it is possible to supply water with an appropriate flow rate without error.
[0063]
Here, the time chart of the present embodiment will be described with reference to FIG. As shown in FIG. 7, in the entire system, when the control unit 100 is turned on and the switching mode is selected, the first mode is started and the measurement of the switching time is started. When the absence of the required amount of water is detected based on the sensor 80 during the first mode, the water supply means 90 starts water supply with the output of the water supply start signal and starts measuring the integrated flow rate or the water supply time. It should be noted that the state where the required amount of water is present can be detected by the sensor 80 and the control means 100 when the water reaches the sensor 80 after the start of water supply. In this embodiment, the required water content by the sensor 80 and the control means 100 is detected. The process for determining whether or not there is an amount has stopped. Further, when the integrated flow rate value reaches the upper limit value or the measurement of the water supply time is completed, a water supply end signal is output and the water supply is ended. The above is repeated during the first mode.
[0064]
Then, when the measurement of the switching time is completed, the mode is switched to the second mode. When the absence of the required amount of water is detected based on the resistance value of the sensor 80 during the second mode, a predetermined stress time is measured. If the absence of the required water amount is not maintained during the stress time measurement, the stress time is initialized (not shown). If the absence of the required water amount by the sensor 80 is maintained, a water supply start signal is output to supply water. While 90 starts water supply, measurement of the flow rate by the flowmeter 93 or measurement of water supply time is started. It is possible to detect the presence of the required water amount by the sensor 80 and the control means 100 when the water reaches the sensor 80 after the start of water supply. In this embodiment, the presence or absence of the required water amount by the control means 100 can be detected. Judgment processing is stopped. Further, when the integrated flow rate value reaches the upper limit value or the measurement of the water supply time is completed, a water supply end signal is output and the water supply is ended. The above is repeated during the second mode.
[0065]
Although the first embodiment of the present invention has been described above, the effectiveness can be exhibited in the following cases by using the first embodiment. For example, when cut grass is used as a plant immediately after construction of a plant cultivation unit on the laying surface, the cut grass is not rooted in the soil, and an air layer is formed between the root of the cut grass and the soil. As a result, it becomes the weakest state (a state that is easy to wither). In this state, it is a time when a lot of water is necessary, and it is necessary to root as soon as possible to prevent the lawn from withering. By performing the water supply process in the first mode of the first embodiment at this time, grass rooting can be stopped. In addition, it is possible to cultivate turf in a more natural state by constructing the turf after rooting to automatically switch to the second mode, and it is possible to cultivate a strong turf. . In other words, the switching mode selection unit 106 does not select the non-switching mode immediately after the construction, but the switching time is set so that, for example, two weeks after the turf will take root, the control as described above is performed. It becomes possible.
[0066]
Next, the second example in the automatic water supply system of the plant cultivation unit of the above embodiment will be described in detail with a focus on differences from the first example. FIG. 8 is a flowchart showing the overall flow of the water supply control process in the second embodiment, and FIG. 9 is a time chart of the automatic water supply system of the second embodiment. Further, the configuration of the plant cultivation unit, the configuration for detecting the presence or absence of the required water amount based on the sensor 80 in the water storage tray 10, the configuration for supplying water into the water storage tray 10, the processing in the second mode and the contents of the system block are the first embodiment. It is the same.
[0067]
In the present embodiment, a predetermined water supply interval time is measured by the timer unit 103 during the first mode, and water is supplied every this water supply interval time. The set time of the water supply interval time is appropriate, but is set to, for example, 3 days when the water in the water storage tray 10 will disappear. By using the second embodiment, the same effects as those of the first embodiment can be obtained, such as nurturing turf that is fastened and fastened.
[0068]
As shown in FIG. 8, the details of the first mode are determined by turning on the power of the control means 100 and selecting the switching mode to enter the execution state, selecting the switching mode and not selecting the non-switching mode. (S1, S2, S3), the first mode is started (S4). When the first mode is started, measurement of a predetermined switching time is started by the timer unit 103 (S5), and further, measurement of a predetermined water supply interval time is started (S18). When the measurement of the switching time is completed (S6), the switching time of the timer unit 103 and the water supply interval time are initialized and the mode is switched to the second mode as in the first embodiment (S21, S10).
[0069]
If the measurement of the water supply interval time is not completed during the measurement of the switching time, the process returns to the determination process whether the measurement of the switching time is completed again or every predetermined time interval (S6). When the measurement of the interval time is completed (S6, S19), the water supply interval time of the timer unit 103 is initialized (S20), and the water supply process is performed as in the first embodiment (S8). After completion of the water supply process, the timer unit 103 starts measuring the water supply interval time again (S18). When measurement of the switching time is completed during the water supply process (S6) or the like, the water supply process is given priority in the water supply control process of the present embodiment, and the mode is switched to the second mode after the execution of the water supply process is completed. .
[0070]
In the time chart of the entire automatic water supply system of the present embodiment, as shown in FIG. 9, when the control unit 100 is turned on and the switching mode is selected, the first mode is started and the timer unit 103 starts the switching time and water supply. Start measuring the interval time. When the measurement of the water supply interval time is completed during the first mode, a water supply start signal is output, water supply is started by the water supply means 90, and flow rate measurement or water supply time measurement is started by a flow meter. When the integrated flow rate value by the flow meter reaches the upper limit value or the measurement of the water supply time is completed, a water supply end signal is output to end the water supply by the water supply means. The above is repeated during the first mode. When the measurement of the switching time is finished, the mode is switched to the second mode. This second mode is the same as in the first embodiment.
[0071]
Next, the details of the third example in the automatic water supply system of the plant cultivation unit of the above embodiment will be described with a focus on the differences from the first example and the second example. 10 to 12 show a third embodiment of the present invention, FIG. 10 is a system block diagram when water supply control is performed by a timer in the third embodiment, and FIG. 11 is a flowchart showing the entire flow of water supply control processing. FIG. 12 is a time chart of the automatic water supply system of the third embodiment. The configuration of the plant cultivation unit, the configuration for supplying water into the water storage tray 10 and the like are the same as those in the first and second embodiments, and the first mode processing content is the same as in the second embodiment.
[0072]
In the present embodiment, during the first mode, the first water supply interval time is set in the same manner as the three days illustrated in the second embodiment, the measurement start of the first water supply interval time (S22), and the first water supply interval time. Water supply is performed at intervals of the first water supply interval time by processing such as determination of measurement end (S23), initialization of the first water supply interval time of the timer unit 103 (S24), etc. A second water supply interval time that is longer than the water supply interval time is set, and water is supplied every second water supply interval time. As shown in FIG. 10, it is a structure which does not use the sensor part 80, and it becomes possible to provide the automatic water supply system which was cheaper and the processing content was simplified.
[0073]
As shown in FIG. 11, when the non-switching mode is selected by the switching mode selection unit 106 (S3), the measurement of the switching time is ended during the first mode (S6), and the timer unit 103 is initialized. The second mode is started (S21, S10). When the second mode starts (S10), the timer unit 103 measures the second water supply interval time, which is longer than the first water supply interval time, as 10 days, for example (S25), and the second water supply interval time is measured. It is determined whether or not the processing has been completed continuously or at predetermined intervals (S26). When the measurement of the second water supply interval time is completed, the second water supply interval time of the timer unit 103 is initialized (S27), and the water supply process is executed in the same manner as in the first and second embodiments (S17). After the end of the water supply process, the timer unit 103 starts measuring the second water supply interval time again. The above process is repeatedly executed during the second mode.
[0074]
That is, as shown in FIG. 12, after the measurement of the switching time, the mode is switched to the second mode, and the measurement of the second water supply interval time is started. Then, every time the measurement of the second water supply interval time is completed, a water supply start signal is output to the water supply means 90 and water supply by the water supply means 90 is started. After the start of water supply, the water supply end signal is output in response to the flow rate value measured by the flow meter reaching the upper limit value or the measurement of the water supply time is ended, and the water supply means 90 ends the water supply process.
[0075]
In the present embodiment, the case where the water supply control is performed only by the control by the timer has been described. However, the present invention is not limited to this, and the control by the flow meter is performed similarly to the first embodiment and the second embodiment. It is also possible to perform a combination of control by a flow meter.
[0076]
Next, the details of the fourth example in the automatic water supply system of the plant cultivation unit of the above embodiment will be described focusing on the differences from the first example, the second example, and the third example. FIGS. 13 and 14 show a fourth embodiment of the present invention, FIG. 13 is a flowchart showing the overall flow of the water supply control process, and FIG. 14 is a time chart of the automatic water supply system of the fourth embodiment. The configuration of the plant cultivation unit, the configuration for supplying water into the water storage tray 10 and the like are the same as those in the first, second and third embodiments.
[0077]
In the present embodiment, in both the first mode and the second mode, the presence / absence of the required moisture amount is determined based on the resistance value acquired by the sensor 80 at the moisture state detection location, and the absence of the required moisture amount is detected. Is configured to start the measurement of the predetermined first stress time and the second stress time by the timer unit 103 and to supply water when the state without the required amount of water is maintained until the end of the measurement of the predetermined stress time. It is. The first stress time that is the stress time in the first mode is set to a relatively short time, for example, 3 days, and the second stress time that is the stress time in the second mode is, for example, 7 days. By setting a relatively long period of time and different conditions for starting water supply, for example, it is effective to quickly root the turf root in the soil and grow healthy turf.
[0078]
That is, as shown in FIG. 13, the control unit 100 is turned on to select the switching mode or the non-switching mode (S1, S2), and it is determined whether the switching mode or the non-switching mode is selected (S3). ). When the non-switching mode is selected, the second mode is started (S10), and when the switching mode is selected, the first mode is started (S4). Measurement of the switching time is started by the start of the first mode (S5), and the presence or absence of the required moisture amount is determined based on the detection of the sensor 80 until the switching time ends (S6, S7), and the required moisture amount. Only when it is determined that there is no, the timer unit 103 starts measuring the first stress time (S28).
[0079]
During the first stress time measurement, the presence / absence of the required water amount is determined continuously or every predetermined time based on the detection of the sensor 80 again (S29). The first stress time is initialized (S30), and the process returns to the determination of whether or not the measurement of the switching time is completed again (S6). Further, when the state without the required water amount is maintained during the first stress time (S31), the first stress time of the timer unit 103 is initialized (S32), the water supply process is performed (S8), and the water supply process is performed. After the end, the process returns to the determination of whether or not the measurement of the switching time has ended (S6). The above process is repeated until the switching time ends, and when the measurement of the predetermined switching time is completed, the switching time of the timer unit 103 is initialized and the process proceeds to the second mode (S6, S9, S10).
[0080]
When the second mode is started (S10), it is determined whether there is a required water amount continuously or at predetermined time intervals based on the detection of the sensor 80 (S11), and only when it is determined that there is no required water amount, the timer unit. The measurement of the second stress time longer than the first stress time is started at 103 (S33). During the second stress time measurement, the presence or absence of the required water amount is determined again continuously or at predetermined time intervals (S13), and when it is determined that the required water amount is present, the second stress time being measured by the timer unit 103 is determined. Initialization is performed (S34), and the process returns to the determination of the presence / absence of the required water amount (S11). When the state without the required water amount is maintained during the second stress time (S35), the second stress time of the timer unit 103 is initialized (S36), the water supply process is performed (S17), and the required water amount is again set. The process returns to the presence / absence determination (S11). The contents of the water supply process are the same as in the first, second and third embodiments.
[0081]
As shown in the time chart of FIG. 14, the operation of the entire automatic water supply system of this embodiment starts the first mode by turning on the power of the control means 100 and selecting the switching mode. When it is determined that there is no required water amount based on the detection of the sensor 80 during the first mode, measurement of a predetermined first stress time is started, and if the state without the required water amount is not maintained during the first stress time, One stress time is initialized (not shown). Also, if the state without the required amount of water is maintained during the first stress time, a water supply start signal is output and the water supply means 90 starts water supply, and also starts measuring the flow rate or the water supply time with a flow meter. . When the integrated flow rate value by the flow meter reaches the upper limit value or the measurement of the water supply time is completed, a water supply end signal is output and the water supply by the water supply means 90 ends.
[0082]
When the measurement of the switching time is completed, the switching time is initialized and the mode is switched to the second mode. When a determination result indicating that the required water amount is absent is obtained based on the detection of the sensor 80 during the second mode, measurement of a predetermined second stress time is started. If the absence of the required water amount is not maintained during the second stress time, the second stress time is initialized (not shown). Further, if the absence of the required amount of water is maintained during the second stress time, a water supply start signal is output and the water supply means 90 starts water supply, and at the same time, starts measuring the flow rate or the water supply time with a flow meter. When the integrated flow rate value by the flow meter reaches the upper limit value or the measurement of the water supply time is completed, a water supply end signal is output and the water supply by the water supply means 90 ends. The above is repeated during the second mode.
[0083]
In this embodiment, the stress time such as the first and second stress times can be set differently or appropriately changed for each stress time, and various stress times can be set according to the installation location, environment, and plant type. Therefore, it is possible to provide an automatic water supply system that better meets the user's wishes.
[0084]
Next, the details of the fifth example in the automatic water supply system of the plant cultivation unit of the above embodiment will be described with a focus on differences from the first, second, third, and fourth examples. 15 to 20 show a fifth embodiment of the present invention, FIG. 15 is a system block diagram when water supply control is performed by a timer, FIG. 16 is a flowchart showing the entire flow of water supply control processing, and FIG. FIG. 18, FIG. 19, and FIG. 20 are flowcharts showing the processing when the calendar part time = 1, 2, and 3, respectively. In addition, 5th Example is an Example which considered the case where the plant cultivation unit etc. were installed outdoors, and considered the life maintenance etc. of the turf of the dormant period by natural rainfall, and is the 1st water supply which does not supply water at all. The three modes are set according to the time, so to speak, the time until the third mode is ended is set as the water supply interval time as a whole, but the usage mode is appropriate.
[0085]
In this embodiment, as shown in FIG. 15, the control means 100 has a calendar unit 108, and the calendar unit 108 can check the current date and time (at least the month), and the mode is switched according to the date and time of the calendar unit 108. In addition to the configuration, when the switching mode selection unit 106 selects the switching mode, the first mode is executed. That is, the mode that is switched after the first mode is executed is determined by the calendar unit 108, and the first mode is executed immediately after the start, and the mode is changed according to the season and the like thereafter. is doing.
[0086]
As shown in FIG. 16, the control unit 100 is turned on and the switching mode selection unit 106 performs mode selection (S1, S2) to determine whether the switching mode or the non-switching mode is selected (S3). If the non-switching mode is selected, the process proceeds to A. If the switching mode is selected, the first mode is started as in the first embodiment (S4), and the timer unit 103 starts measuring a predetermined switching time. (S5). Until the measurement of the switching time is completed, the determination of the presence or absence of the required water amount is performed continuously or repeatedly at predetermined intervals based on the detection of the sensor 80 (S6, S7), and it is determined that there is no required water amount Only the water supply process is performed (S8). When the measurement of the switching time is completed, the switching time measured by the timer unit 103 is initialized (S6, S9).
[0087]
After the initialization of the switching time, the CPU 101 determines the time of the calendar unit 108 and determines the mode based on the determination result. For example, in FIG. 16, when it is determined that the time based on the calendar unit 108 = time 1, the process proceeds to B (S <b> 37), and when it is determined that the time = time 2, the process proceeds to C (S <b> 38). If it is determined that it is time 3, the process proceeds to D (S39). In any mode such as the first, second, third, fourth, and fifth embodiments, when the non-switching mode is selected by the switching mode selection unit 106, the control means 100 performs non-switching within a predetermined process. Transition to switching mode processing.
[0088]
When A is shifted, the second mode is started as shown in FIG. 17 (S10). When the second mode is started, the determination of the presence or absence of the required water amount is continuously performed based on the detection of the sensor 80. Alternatively, it is performed at predetermined intervals (S11), and when it is detected that there is no required water content, the timer unit 103 starts measuring a predetermined stress time (S12). Even during the measurement of the stress time, the determination of the presence or absence of the required water amount is performed continuously or at predetermined intervals (S13). If it is determined that the required water amount is present, the timer unit 103 initially sets the stress time being measured. (S14), and the process returns to the determination of the presence or absence of the required water amount again (S11). When the required amount of water is maintained during the stress time (S15), the stress time measured by the timer unit 103 is initialized (S16), and a water supply process is performed (S17). The water supply process is performed, for example, until a predetermined water supply time elapses or until the integrated flow rate reaches a predetermined upper limit, and after the water supply process is completed, the process returns to the determination of the presence or absence of the required water amount (S11).
[0089]
After shifting to B, the modified first mode is started as shown in FIG. 18 (S40), and it is confirmed from time to time whether or not the time has been changed by the calendar unit 108 (S41), and there is no time change. In this case, the presence / absence of the required water content is determined based on the detection of the sensor 80 (S42), and the water supply process is performed only when the determination result indicating that there is no required water content is obtained (S43). On the other hand, when the time is changed by the calendar unit 108, if the time of the calendar unit 108 = time 2 moves to C (S44), and if the time = time 3 moves to D (S45).
[0090]
After shifting to C, the second mode modified as shown in FIG. 19 is started (S46), and it is confirmed at any time whether or not the time has been changed by the calendar unit 108 (S47), and there is no time change. In this case, the presence / absence of the required water amount is determined based on the detection of the sensor 80 (S48), and measurement of a predetermined stress time is started only when a determination result indicating that there is no required water amount is obtained (S49). Only when the state without the required amount of water is maintained during the time (S50, S51), the stress time is initialized and the water supply process is performed (S52, S53), and the state without the required amount of water is not maintained Then, the measurement of the stress time of the timer unit 103 is initialized (S54), and the process returns to the determination of whether or not the time of the calendar unit 108 has been changed again (S47). When the time of the calendar unit 108 is changed, the process moves to B if the time of the calendar part 108 = time 1 (S55), and moves to D if the time = time 3 (S56). .
[0091]
After shifting to D, the third mode is started as shown in FIG. 20 (S57), and it is repeatedly confirmed whether or not the time has been changed by the calendar unit 108 until the time is changed (S58). If there is a time change, the process moves to B if the time of the calendar unit 108 = time 1 (S59), and to C if the time = time 2 (S60).
[0092]
As described above, by using the fifth embodiment of the present invention, it becomes possible to perform all the water management throughout the year with this automatic water supply system. For example, when the turf grows in March etc., the first mode is executed, For the turf from April to October, etc., cultivate in a more natural state by executing the second mode, and to execute the third mode in the turf dormancy period from November to February, etc. This makes it possible to maintain the life of turf with only natural rain and water stored in the water storage tray 10 or soil to some extent, and can perform plant growth management such as good turf management with the minimum necessary water. it can. In the above example, time 1 means March, time 2 means April to October, and time 3 means November to February.
[0093]
And even when using the automatic water supply system of the present invention as described above and forming a greening unit formed by laying a plurality of the plant cultivation units as shown in FIG. 21, water supply management is easy and appropriate. The greening unit can also have an excellent appearance. For example, when laying a plurality of plant cultivation units, for example, a porous pipe is used as the water supply pipe 91, and the water supply pipe 91 is arranged on the water storage tray 10 and between the inward recessed portions 22 a and 22 a of the side wall 22 of the plant cultivation container 20. It is possible to form a greening area having an excellent appearance. Note that 110 is a light, 120 is a curb, and 130 is a wood deck.
[0094]
In addition, the wiring of the light 110 in the case of providing the light unit on which the light 110 is placed, the wire connecting the sensor 80 and the control means 100, and the like are indented portions on the water storage tray 10 and the side wall 22 of the plant cultivation container 20. It becomes possible to arrange | position between 22a * 22a. Further, if a concave groove for running water is formed in the upper end portion of the side wall 22 of the water storage tray 10 (not shown in the figure) and the direction of running water is regulated by this concave groove in one direction, water supply by the porous pipe is performed. Can be performed uniformly in all the water storage trays 10.
[0095]
As mentioned above, although the Example of this invention was described, this invention is not limited to the said Example, The following expansion and deformation | transformation are also attained. For example, when a plurality of sensors 80 are used while forming a greening area, a configuration in which the sensors 80 are installed in all the water storage trays 10 or in any water storage tray 10, for example, at least one sensor 80 of the plurality of sensors 80.
