The present invention relates to a greenhouse having a skylight whose opening and closing are controlled by a skylight control means, a temperature sensor provided in the greenhouse, and a deviation and measurement of a predetermined set value difference from the measured value of the temperature sensor. Based on the increase rate of the measured value calculated from the value (a) If the deviation is positive and the increase rate is positive or zero, or if the deviation is zero and the increase rate is positive, open the skylight (b) If the deviation is positive If the increase rate is negative, or the deviation is zero and the increase rate is zero, or the deviation is negative and the increase rate is positive, then the skylight is stopped. (c) The deviation is zero and the increase rate is negative, or the deviation is zero. When the increase rate is zero or negative, the skylight opening/closing means is driven to close the skylight when the increase rate is zero or negative, thereby controlling the opening degree of the skylight.

割合）に基く天窓２の開閉駆動量を示す。 In the figure, the vertical axis is the deviation calculated from the measured value of the temperature sensor 3 by a predetermined set value, and the horizontal axis is the slope (i.e., the difference between the previous measured value and the current measured value of the temperature sensor 3). (increase rate of the measured value calculated from the measured value of the temperature sensor 3) indicates the opening/closing driving amount of the skylight 2 based on the deviation and the slope (increase rate).
つまり、最初の状態において、天窓２が全開と

割合ともマイナスであると、さらに、天窓２は
所定量閉方向に駆動される。(0) For example, the measured value is smaller than the set value, the deviation is negative, and the rate of increase is also negative (bottom right of Figure 2).The temperature inside greenhouse 1 is predicted to decrease further in the future, so skylight 2 should be closed. direction by a predetermined amount. If both the deviation and the rate of increase are negative, then the skylight 2 is further driven in the closing direction by a predetermined amount.
(1) また、偏差、増加割合、ともにプラスの場合
（第２図左上）、天窓２を開とし、外気を流入さ
せ、温度を下げる。(1) Also, if both the deviation and the increase rate are positive (upper left of Figure 2), open the skylight 2 to let outside air flow in and lower the temperature.
(2) 偏差がプラスで増加割合がゼロのときは、ま
だ温度が高いので天窓２は開とし温度を下げ
る。(2) When the deviation is positive and the rate of increase is zero, the temperature is still high, so skylight 2 is opened to lower the temperature.
(3) 偏差がプラスで増加割合がマイナスのとき
は、自然に温度が下降するので天窓２は停止で
ある。(3) When the deviation is positive and the rate of increase is negative, the skylight 2 is stopped because the temperature naturally falls.
(4) 偏差がゼロで増加割合がプラスのときは、天
窓２を開とし、温度を下げる。(4) When the deviation is zero and the rate of increase is positive, open skylight 2 and lower the temperature.
(5) 偏差、増加割合、ともにゼロのときは、天窓
２は停止である。(5) When both the deviation and the rate of increase are zero, skylight 2 is stopped.
(6) 偏差がゼロ、増加割合がマイナスのときは、
温度が下降するので天窓２は閉とする。(6) When the deviation is zero and the increase rate is negative,
Skylight 2 will be closed as the temperature will drop.
(7) 偏差がマイナスで、増加割合がプラスのとき
は、温度が上昇中なので天窓２は停止する。(7) When the deviation is negative and the rate of increase is positive, the temperature is rising, so skylight 2 will stop.
(8) 偏差がマイナスで、増加割合がゼロのとき
は、温度が低いので天窓２は閉とする。(8) When the deviation is negative and the rate of increase is zero, the temperature is low, so skylight 2 is closed.
このようにして、偏差と増加割合を利用して、
ある程度予測して制御を行つているので制御性が
良好である。 In this way, using the deviation and the increase rate,
The controllability is good because the control is performed with some degree of prediction.
