以下に本発明の一実施例による栽培中作物の生育状態測定装置について説明する。
図１（ａ）は本発明の一実施例による栽培中作物の生育状態測定装置を示すブロック図、図１（ｂ）は同生育状態測定装置が測定対象とする植物の測定部位を示す図、図１（ｃ）は、同測定部位に装着する生体保持構造体を示す図である。
An apparatus for measuring the growth state of a crop under cultivation according to an embodiment of the present invention will be described below.
Fig. 1 (a) is a block diagram showing a growing condition measuring apparatus for a growing crop according to an embodiment of the present invention, and Fig. 1 (b) is a diagram showing measurement sites of plants to be measured by the same growing condition measuring apparatus. FIG. 1C is a view showing a biological holding structure attached to the same measurement site.
本実施例による栽培中作物の生育状態測定装置は、植物１の測定部位１ａ、１ｂ、１ｃに対する照射光を発生する光源１１と、光源１１の照射タイミングを制御する投光制御部１２と、測定部位１ａ、１ｂ、１ｃからの検出光を受光する受光部１３と、受光部１３の受光タイミングを制御する受光制御部１４と、受光部１３で受光した検出光から、植物１の栄養状態を示す成分量を算出する演算部１５と、演算部１５で算出した成分量を時刻情報とともに記憶する記憶部１６とを備えている。
また、本実施例による栽培中作物の生育状態測定装置は、植物１の測定部位１ａ、１ｂ、１ｃに装着する生体保持構造体２０と、光源１１で発生させた照射光を測定部位１ａ、１ｂ、１ｃに導く投光ファイバ１７と、測定部位１ａ、１ｂ、１ｃからの検出光を受光部１３に導く受光ファイバ１８とを備えている。
The apparatus for measuring the growth state of a crop under cultivation according to the present embodiment includes a light source 11 for generating irradiation light to the measurement sites 1a, 1b and 1c of the plant 1, a light projection control unit 12 for controlling the irradiation timing of the light source 11, and measurement. From the detection light received by the light receiving unit 13 that receives the detection light from the portions 1a, 1b, and 1c, the light reception control unit 14 that controls the light reception timing of the light reception unit 13, and the detection light received by the light receiving unit 13, The calculation unit 15 calculates component amounts, and the storage unit 16 stores the component amounts calculated by the calculation unit 15 together with time information.
In addition, the apparatus for measuring the growth state of the crop under cultivation according to the present embodiment includes the biological support structure 20 attached to the measurement sites 1a, 1b and 1c of the plant 1, and the irradiation light generated by the light source 11 as the measurement sites 1a and 1b. , And 1c, and a light receiving fiber 18 for guiding the detection light from the measurement portions 1a, 1b, and 1c to the light receiving unit 13.
ここで、測定対象となる植物１は、収穫前の生育段階にある栽培中作物であり、測定部位１ａは茎、測定部位１ｂは果柄、測定部位１ｃは葉柄である。
光源１１には、ウォーミングアップ時間が無く、時間応答性の高い発光ダイオードを用いることが好ましく、波長の異なる複数の発光ダイオードを用いる。
Here, the plant 1 to be measured is a crop under cultivation in a growth stage before harvest, the measurement site 1a is a stem, the measurement site 1b is a stem, and the measurement site 1c is a stem.
As the light source 11, it is preferable to use a light-emitting diode that does not have a warm-up time and has a high time response, and uses a plurality of light-emitting diodes having different wavelengths.
受光部１３に分光器を用いる場合には、投光制御部１２では、複数の発光ダイオードの照射タイミングを同じとする。受光部１３に分光器を用い、複数の発光ダイオードの照射タイミングを同じとすることで、限られた時間で投光時受光信号を得ることができるため、環境光の変化の影響を受けにくい。
受光部１３にフォトダイオードを用いる場合には、投光制御部１２では、それぞれの発光ダイオードの照射タイミングを異ならせる。受光部１３に簡易なフォトダイオードを用いることで安価に装置を構成できる。
When a spectroscope is used as the light receiving unit 13, the light emission control unit 12 sets the irradiation timing of the plurality of light emitting diodes to be the same. By using a spectroscope in the light receiving unit 13 and making the irradiation timings of the plurality of light emitting diodes the same, it is possible to obtain a light reception signal at the time of light projection in a limited time, so it is difficult to be affected by changes in ambient light.
When a photodiode is used as the light receiving unit 13, the light emission control unit 12 makes the irradiation timings of the respective light emitting diodes different. By using a simple photodiode for the light receiving unit 13, the apparatus can be configured at low cost.
投光制御部１２での光源１１の照射時間（パルス幅）は、環境光の変動に対応するために十分に早い時間、例えば１／１０秒〜１／１０００秒の時間とすることが好ましい。さらに、一回の受光測定時間は、前述の照射時間で瞬時に完結するため、複数回の測定データを積算化、又は平均化することにより測定データの精度を向上できる。
非投光時受光信号の検出は、照射タイミングに限りなく近い時間が好ましいが、照射タイミングの直前は一つ前の照射時間の後、照射タイミングの直後は一つ後の照射時間の前であればよい。
The irradiation time (pulse width) of the light source 11 in the light projection control unit 12 is preferably set to a sufficiently fast time, for example, 1/10 seconds to 1/1000 seconds, in order to cope with fluctuations in ambient light. Furthermore, since one light reception measurement time is instantaneously completed in the above-mentioned irradiation time, the accuracy of measurement data can be improved by integrating or averaging a plurality of measurement data.
The detection of the light reception signal at the time of non-flooding is preferably as close as possible to the irradiation timing, but immediately before the irradiation timing after the previous irradiation time and immediately after the irradiation timing before the next irradiation time Just do it.
植物１の栄養状態を示す成分量には、硝酸態窒素量、炭水化物量、タンパク質量、ミネラル成分量、抗酸化物質量、及び水分量の少なくともいずれか一つを含む。 The component amount indicating the nutritional status of the plant 1 includes at least one of nitrate nitrogen amount, carbohydrate amount, protein amount, amount of mineral component, amount of antioxidant, and amount of water.
演算部１５では、光源１１の照射タイミングでの検出光による投光時受光信号と、照射タイミングの直前又は直後での検出光による非投光時受光信号との差分を用いて演算処理する。このことで、特に栽培環境下で最も強いノイズである太陽光（直流光）の影響をキャンセルでき、環境光とのＳ／Ｎを向上させることができるので、収穫前の生育段階にある栽培中作物に対して、露地・ハウス内等の栽培現場にて、非接触・非破壊で、植物１の栄養状態を連続測定できる。 The arithmetic unit 15 performs arithmetic processing using the difference between the light reception signal at the time of light emission by the detection light at the irradiation timing of the light source 11 and the light reception signal at the time of non-light emission by the detection light immediately before or after the irradiation timing. In this way, the influence of sunlight (direct current light), which is the strongest noise particularly in the cultivation environment, can be canceled, and the S / N with the ambient light can be improved. With respect to the crop, the nutrient status of the plant 1 can be continuously measured in a non-contact and non-destructive manner at the cultivation site such as in an open area or in a house.

演算部１５では、投光時受光信号から、照射タイミングの直前又は直後での非投光時受光信号を減算することで、外乱光や太陽光の影響をキャンセルできる。
FIG. 2 shows an output signal from the light emission control unit in the growing condition measuring apparatus according to the present embodiment and a light reception signal from the light receiving unit.
Fig.2 (a) is an output signal in a light projection control part, Fig.2 (b) is a light reception signal in a light receiving part in case the noise by disturbance light influences, FIG.2 (c) is sunlight in the daytime. The light reception signal in the light reception part in the case is shown, and FIG. 2D shows the light reception signal in the light reception part at night.
The operation unit 15 can cancel the influence of disturbance light and sunlight by subtracting the non-light-projected light reception signal immediately before or after the irradiation timing from the light-projected light reception signal.
図３は、受光部にフォトダイオードを用いた場合の本実施例による生育状態測定装置における投光制御部での出力信号と、受光部での受光信号を示している。
投光制御部１２では、それぞれの発光ダイオードの照射タイミングを異ならせることで、それぞれの発光ダイオードによる投光時受光信号を得ることができる。この場合にも、演算部１５では、発光ダイオードａによるＬＥＤａ投光時受光信号から、ＬＥＤａ投光時受光信号の直前での非投光時受光信号を減算し、発光ダイオードｂによるＬＥＤｂ投光時受光信号から、ＬＥＤｂ投光時受光信号の直前での非投光時受光信号を減算し、発光ダイオードｃによるＬＥＤｃ投光時受光信号から、ＬＥＤｃ投光時受光信号の直前での非投光時受光信号を減算することで、外乱光や太陽光の影響をキャンセルできる。
FIG. 3 shows an output signal from the light projection control unit in the growing condition measuring apparatus according to the present embodiment when a photodiode is used as the light receiving unit, and a light receiving signal from the light receiving unit.
The light emission control unit 12 can obtain light reception signals at the time of light emission by the respective light emitting diodes by making the irradiation timings of the respective light emitting diodes different. Also in this case, the arithmetic operation unit 15 subtracts the light reception signal at the time of non-light emission just before the light reception signal at the time of LEDa light emission from the light reception signal at the time of LEDa light emission by the light emitting diode a From the light reception signal, subtract the light reception signal at non-light emission time just before the light reception signal at LEDb light emission time, and from the light reception signal at LEDc light emission time by the light emitting diode c By subtracting the light reception signal, it is possible to cancel the influence of ambient light and sunlight.
本発明による栽培中作物の生育状態測定装置は、露地栽培やハウス栽培での植物を、昼夜を問わず、栽培期間中継続して生育状態を測定することができる。 The apparatus for measuring the growing condition of crops under cultivation according to the present invention can measure the growing condition of plants in open field cultivation and house cultivation continuously during the cultivation period regardless of day and night.
