When the circulating water pump 33 is energized under the control of the system controller C, the air pump 11 is also energized, and when the circulating water pump 33 is de-energized, the air pump 11 It is set to stop the energization to.

<Air-cooled cooler control>
When the temperature of the circulating water measured by the circulating water tank temperature sensor 38 is 25 ° C. or higher and is higher than the outside air temperature measured by the outside air temperature sensor 41, the system control unit C sends a control signal to the power supply control unit 15.

  As described above, in the wall surface greening system of the present embodiment, the circulating water control unit 8 supplies rainwater when the amount of stored rainwater is larger than a predetermined amount, and supplies clean water when the amount of rainwater is equal to or less than the predetermined amount. Therefore, by supplying clean water according to the amount of stored rainwater, it is possible to conserve tap water and other water as much as possible to reduce water costs, and stable automatic irrigation for a long time. Can be maintained.

  In addition, the circulating water control unit 8 supplies water in the water supply tank 12 to the circulating water tank 13 when the circulating water amount in the circulating water tank 13 is equal to or less than a predetermined amount, and the water amount in the water supply tank 12 is a predetermined amount.

Will be supplied, and a stable circulating water supply will be possible.

  Furthermore, since the circulating water circulation mechanism 5 includes the circulating water temperature control unit 9 for controlling the temperature of the circulating water, water can be irrigated at a temperature suitable for the plant P, and the water temperature is particularly high even in rainwater whose temperature changes drastically depending on the weather and season. Control becomes possible. For example, in summer, the temperature of rainwater stored at 30 ° C. or higher, where the plant P decays, may increase. According to the present system, this can be prevented by appropriate temperature control of irrigation.

In addition, the liquid fertilizer addition mechanism 10 adds liquid fertilizer to the circulating water and controls the liquid fertilizer concentration of the circulating water. Therefore, it is possible to promote the good growth of the plant P.
Moreover, since the air pump 11 supplies oxygen to circulating water, oxygen shortage of circulating water can be compensated. In particular, in the case of stored rainwater as compared with tap water or the like, the oxygen concentration may not be sufficient, and this system can prevent oxygen shortage.

  Moreover, when the power supplied from the solar panel 14 reaches the required power amount, the power supply control unit 15 supplies the power, and the power supplied from the solar panel 14 reaches the required power amount. In the case where there is not, by supplying power from the commercial power source, it is possible to use solar power generation as much as possible by automatic power source switching and reduce the electric cost of the commercial power source.

  In addition, since the information communication mechanism 7 transmits the control information in the circulating water circulation mechanism 5 by wireless communication or wired communication, whether rainwater is sufficiently stored or normal irrigation is executed from the received control information, Various system conditions such as whether or not an abnormality has occurred in the system can be obtained at a remote location, and when an abnormality occurs, a quick response can be made.

  Further, the information communication mechanism 7 can receive not only the control information transmission function but also an operation signal from a remote place, and controls the circulating water circulation mechanism 5 based on the operation signal. Since control can be performed from a remote location, it is not necessary for an operator to visit the site where the system is installed, and the system can be managed and operated remotely from a remote location.

  Further, since the information communication mechanism 7 transmits the image data or video data of the plant P photographed by the camera 47 by wireless communication or wired communication, the image data or video data is received at a remote place and the state of the plant P is imaged. Or it can be confirmed directly on the video. For example, the state of the plant P can be confirmed at a remote place such as when the plant P becomes sick or when an insect is attached to the plant P.
