The control unit C is connected to an input unit 91, a weight scale 70, and a wireless communication unit 92, and includes a cylinder remaining amount calculation unit c1 and a cylinder remaining amount notification unit c2.

The input unit 91 is composed of operation keys and the like, and receives input of various information from the user.

The wireless communication unit 92 includes an interface for communicating with an external device via a wireless LAN (Local Area Network) or the like, and wirelessly communicates with the weighing scale 70 and the information terminal 80 via an antenna (not shown).

The cylinder remaining amount calculation unit c1 acquires the weight information sent from the weight scale 70 at predetermined time intervals via the wireless communication unit 92. Here, the weight information includes identification information that uniquely identifies the plurality of weight scales 70. Therefore, the cylinder remaining amount calculation unit c1 determines from the acquired weight information which weight scale 70 the measured value of the weight included in the weight information is the weight of the cylinder B installed in each of the weight scales 70. That is, it is possible to grasp the weight of each cylinder B arranged on the pedestal 10 in real time.

Further, in the cylinder remaining amount calculation unit c1, the weight of the cylinder B when the gas in the cylinder B is empty is input by the user from the input unit 91 and stored in advance for each cylinder B, that is, for each of the weight scales 70. Has been done. As a result, the cylinder remaining amount calculation unit c1 calculates the weight of the gas in the cylinder B by calculating the difference between the acquired measured value of the weight of the cylinder B and the weight when the cylinder B stored in advance is empty. To do. As a result, the remaining amount of gas in the cylinder B can be calculated from the calculated weight of the gas in the cylinder B for each cylinder B, that is, for each weight meter 70. As described above, according to the configuration in which the remaining amount of gas in the cylinder B is calculated based on the weight of the cylinder B, it is more accurate than the method of measuring the pressure in the cylinder B and calculating the remaining amount of gas. You can grasp the remaining amount.

The cylinder remaining amount notification unit c2 acquires the remaining amount of gas in the cylinder B for each of the calculated weight scales 70 from the cylinder remaining amount calculation unit c1, and the remaining amount of gas in the cylinder B is equal to or less than the set value. In order to notify the user of this, an alert (notification information) for notifying that the remaining amount of gas is low or has run out is transmitted to the information terminal 80 in the form of a mail via the wireless communication unit 92. .. It should be noted that this set value is input from the input unit 91 by the user and stored in advance for each cylinder B, that is, for each weight scale 70, and can be set to a value desired by the user at any time by input from the input unit 91. It can be changed.

Further, the cylinder remaining amount notification unit c2 receives a request from the information terminal 80 via the wireless communication unit 92, and the remaining amount of gas in the cylinder B for each weight meter 70 calculated by the cylinder remaining amount calculation unit c1. Is transmitted to the information terminal 80. As a result, the user can check the remaining amount of gas in the cylinder B from the information terminal 80 at any time.

The information terminal 80 is not particularly limited as long as it is an information processing device that can be connected to an Internet line and has an information display function such as e-mail. For example, general-purpose computers such as personal computers, mobile computers, mobile phones, and the like are also included.

Since the cylinder stand 1 configured as described above is configured to be able to supply the electricity generated by the power generation unit 30 to the booster 50 that boosts the gas in the cylinder B, the running cost can be suppressed, and in addition, Therefore, it is possible to operate in places where it is difficult to secure a power source. As a result, the installation location of the cylinder B can be freely designed. When the cylinder B is filled with carbon dioxide, the cultivated plants in the cultivation house perform photosynthesis only during the daytime when sunlight is emitted. Therefore, it is necessary to increase the pressure by the booster 50 for cultivation in the cultivation house. It is during the day when carbon dioxide is supplied to the plants. Therefore, the booster 50 can be driven by utilizing the power generation of the solar panel 41 during the daytime, and the running cost can be satisfactorily reduced.

In addition, the control unit C calculates the remaining amount of gas in the cylinder B based on the weight of the cylinder B, and further sends the notification information to the information terminal 80 in the form of an e-mail according to the calculated remaining amount of gas. Since it is configured to transmit, the user can know the exact remaining amount of gas in the cylinder B at an appropriate timing.

The portion 32 may be provided to cover the left and right sides of the cylinder B to improve the light blocking effect.

Further, in the above embodiment, the setting of the weight of the cylinder B when the gas in the cylinder B stored in the cylinder remaining amount calculation unit c1 is empty, and the setting and change of the set value of the cylinder remaining amount notification unit c2 are performed. This is performed by accepting the user's operation from the input unit 91, but the information terminal 80 accepts the user's input operation, and the control unit C acquires the information input to the information terminal 80 via the wireless communication unit 92. It may be done by.
