［産業上の利用分野］
本発明は１人工照明によって植物の育成を制御するよう
にした植物育成装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a plant growing device that controls the growth of plants using one artificial light.
［従来の技術］
従来の植物育成装置においては、植物栽培棚と人工照明
装置とは夫々固定されており、栽培棚の照度を調節する
には、照明装置の通電量の増減か、又はその点灯ランプ
数の増減かによらざるを得なかった。[Conventional technology] In conventional plant growing devices, the plant cultivation shelf and the artificial lighting device are each fixed, and the illuminance of the cultivation shelf can be adjusted by increasing or decreasing the amount of electricity supplied to the lighting device or by turning it on. It had to depend on whether the number of lamps was increased or decreased.
人工照明の光源として、白熱電灯、蛍光灯、メタルハラ
イドランプや高圧ナトリウムランプ等があり、白熱電灯
や蛍光灯は電気的に調光が可能であるが、これに対して
、メタルハライドランプや高圧ナトリウムランプ等にお
いては、電気的な調光が不可能であって点滅しかできな
いため、複数個のランプの間引点滅により調光していた
。Light sources for artificial lighting include incandescent lamps, fluorescent lamps, metal halide lamps, and high-pressure sodium lamps.Incandescent lamps and fluorescent lamps can be electrically dimmed; however, metal halide lamps and high-pressure sodium lamps In such cases, electrical dimming is impossible and only blinking is possible, so the dimming was done by thinning out and blinking a plurality of lamps.
［発明が解決しようとする課題］
しかし、光源の間引点滅では、無段階調光ができないと
いう問題があった。[Problems to be Solved by the Invention] However, when the light source is thinned out and blinked, there is a problem in that stepless dimming cannot be performed.
また、光源の劣化、電源電圧の変動、光源と栽培棚の間
の仕切りガラスの汚れあるいは光源ランプ自体の汚れ等
に因る照度低下に対して適切に対応できなかった。Furthermore, it has not been possible to appropriately deal with reductions in illuminance due to deterioration of the light source, fluctuations in power supply voltage, dirt on the partition glass between the light source and the cultivation shelf, dirt on the light source lamp itself, and the like.
本発明は、上述の従来の種々の欠点に鑑みて為されたも
ので、広範囲に無段階に照度の調節を行い得る植物育成
装置を提供することにある。The present invention has been made in view of the various drawbacks of the above-mentioned conventional plants, and it is an object of the present invention to provide a plant growing device that can steplessly adjust illuminance over a wide range.
［課題を解決するための手段］
本発明の最も基本的なものは、植物育成室、該育成室内
に設けられた植物栽培棚、該栽培棚を上方より照明する
照明手段、該照明手段と栽培棚との相対的上下方向移動
を生ぜ゛しぬるための駆動手段を具備した事を特徴とす
る植物育成装置にある。[Means for Solving the Problems] The most basic aspects of the present invention are a plant growing room, a plant growing shelf provided in the growing room, a lighting means for illuminating the growing shelf from above, and a method for using the lighting means and the growing room. There is a plant growing device characterized in that it is equipped with a driving means for causing vertical movement relative to a shelf.
その、より具体的なものは特許請求の範囲の請求項２以
下に記載したものである。More specific examples thereof are described in claims 2 and below.
［作 用コ
照明手段と栽培棚との相対的上下方向移動（これは両者
のうち前者又は後者のいずれの移動によって達成しても
よい）により両者間の距離を変化させ、これにより栽培
棚における照度を無段階的に変えることができる。[Operation] The relative vertical movement between the lighting means and the cultivation shelf (this may be achieved by the movement of either the former or the latter) changes the distance between them, thereby changing the distance between them. The illuminance can be changed steplessly.
更に請求項２の構成によれば、栽培棚に設けた照度セン
サで栽培棚における照度を検出して、運転開始時に設定
した照度と比較して、測定した照度値が、設定した照度
値よりも大きい場合は照明手段と栽培棚との間隔を広げ

る方向に睡動手段が動作し、センサ検出照度が設定照度
となるまで廓動手段が動作して、設定照度と一致した時
点で停止するという制御動作を自動的に行わせる。Furthermore, according to the configuration of claim 2, the illuminance on the cultivation shelf is detected by the illuminance sensor provided on the cultivation shelf, and compared with the illuminance set at the start of operation, the measured illuminance value is found to be higher than the set illuminance value. If the distance is large, the sleeping means operates in the direction of increasing the distance between the lighting means and the cultivation shelf, and in the opposite case, the sleeping means operates in the direction of bringing the lighting means and the cultivation shelf closer together, until the sensor-detected illuminance reaches the set illuminance. The system automatically performs a control operation in which the illuminance starts and stops when the illuminance matches the set illuminance.
かかる開動手段による相対移動のみでは設定照度に対応
し切れず、その移動が限界点を越えようとするときは、
請求項３の構成によれば、ランプ点灯数を変更し、再び
上記の相対移動による照度制御で対応できるようにする
のである。When the relative movement by the opening mechanism alone cannot cope with the set illuminance and the movement is about to exceed the limit,
According to the third aspect of the invention, the number of lamps lit is changed so that the above-mentioned relative movement-based illuminance control can be used again.

A reinforcing member 22 connects the members 17 and 22 is a base, and the motor 15 and guide post 17 are installed on the base 22. Further, an upper limit sensor 18 and a lower limit sensor 19 are attached to the guide post 17, so that the cultivation shelf support plate 20 cannot move beyond the sensors 18 and 19.

駆動装置に与えられて、照度の測定値が設定値と等しく
なるまで栽培棚９を上または下に移動させる。In this configuration, when operating condition data (temperature, humidity, illuminance) is input to the control unit 14 and operation is started, illuminance is controlled as shown in FIG. That is, the number of lamps 6 corresponding to the set illuminance value is lit. After the illuminance stabilizes after several minutes of lighting, the illuminance is measured by the illuminance sensor 7 installed on the cultivation shelf 9, and the control unit 14 adjusts the amount of movement of the cultivation shelf according to the difference between the illuminance setting value and the measured value. This result is given to the driving device for moving the cultivation rack 9 up and down, and the cultivation rack 9 is moved up or down until the measured value of illuminance becomes equal to the set value.

に照度が大きくなりすぎて栽培４！Ｉ９が下限リミット
センサ１９に達した場合には、直ちに下方への移動を止
めランプ６の点灯数を減らし、再び棚上上移動による照
度制御に戻る。If the illuminance decreases significantly due to a burnout of the lamp 6 or other causes, the upward movement of the cultivation shelf 9 will stop as soon as the amount of upward movement of the cultivation shelf 9 increases and the cultivation shelf 9 reaches the upper limit sensor 18. , the number of lighting lamps 6 is increased according to the difference between the measured illuminance value and the set value, and the illuminance measured value is again controlled to match the set value by the above-mentioned movement on the shelf. On the other hand, the illuminance is too high and cultivation is 4! When I9 reaches the lower limit sensor 19, the downward movement is immediately stopped, the number of lighting lamps 6 is reduced, and the illuminance control is returned to by moving on the shelf.
以上のように、設定照度に対してランプの点灯数を選択
して照度を設定照度に粗く近づけ、更に照度の微調整と
して駆動装置により栽培棚を上下動させて設定照度に合

て無段階に精度よく制御し得る。As described above, the illuminance is roughly approximated to the set illuminance by selecting the number of lamps lit for the set illuminance, and furthermore, as a fine adjustment of the illuminance, the cultivation shelf is moved up and down by the drive device to control it to match the set illuminance. Therefore, even if the set illuminance is changed or the luminous intensity of the illumination source is changed, the illuminance can be controlled steplessly and precisely over a wide range.

ンプ群６からの熱線を和らげるため水張り可能とした。In the device of this embodiment, when the cultivation shelf moves up and down and approaches the lamp group 6, there is a possibility that the plants on the cultivation shelf will be affected by the heat from the lamp group. In order to prevent this, a temperature/humidity sensor 8 is attached to the cultivation shelf, and based on the detected value, the air conditioning system for the cultivation room accommodating the cultivation shelf is controlled. The top can be filled with water to soften the heat rays from the lamp group 6.
