The opening / closing device 140 functions to open or close the vinyl covering the green house 100 at one side of the green house 100. At this time, the driving of the opening / closing device 140 may be variously performed, but the main object of the present invention is not in the way of opening and closing, so a detailed description will be omitted.

For example, a method for opening / closing the opening / closing device 140 is described in the Registration Practical Utility Model No. 20-0220157, Registered Utility Model No. 20-0472366.

That is, an example is a constitutional combination of a shaft through which vinyl is wound and rotated and a motor which drives the shaft.

The snow removing apparatus 150 is configured to be attached to the upper outer surface of the vinyl of the green house 100 and specifically includes a motor, a shaft, a connecting member, and a snow removing member to snow on the outer surface of the upper portion of the vinyl do.

The motor is mounted on the motor cover on the upper side of the green house 100, and the motor cover includes wings extending to both sides. A support frame is further provided on one side of the motor in the opposite direction, wherein the support frame and the vane are connected to each other.

The shaft is connected to the motor, is rotated by a rotational force from the motor, and a screw is formed on the outer surface of the shaft.

The snow remover may be formed in the shape of '⌒' so as to correspond to the top surface shape of the green house 100, which is fitted to the shaft and moves forward or backward along the shaft. And both ends of the snow remover can be supported by the support rods while being inserted into the support rods.

The connecting member is inserted into the shaft and moved forward or backward along the shaft, and one side thereof is connected to the snow removing member so that the snow removing member can stably operate.

On the other hand, a cylinder-shaped warm air supply device is installed on one side of the shaft adjacent to the motor to supply warm air to the upper surface of the greenhouse 100. Such a warm air supply can be used to (a) prevent the snow remover from coming too close to the motor, (b) prevent the motor from cooling down in the mid-winter, and (c) It is possible to perform a function of melting snow on the upper surface of the apparatus.

The liquid-absorber 160 is provided inside or outside the greenhouse 100, and functions to supply the nutrient solution under the control of the control unit.

The sensor unit 180 includes a temperature / humidity sensor module, an ultrasonic sensor module, a soil measurement sensor module, and a Co2 measurement sensor module, which are provided in the greenhouse 100 to measure predetermined values .

In the sensor module, the ultrasonic sensor module may be formed on the upper surface of the greenhouse 100, and the rest may be formed inside the greenhouse 100.

The temperature / humidity sensor module measures the temperature and humidity inside the greenhouse 100. At this time, the temperature / humidity sensor module sets the reference value at 25 to 28 DEG C, and at night to 18 to 22 DEG C. [ Also, in measuring the temperature, it is possible to measure the geothermal temperature (ground temperature) provided on the ground. In this case, it is preferable that the set value is set to 18 to 24 DEG C regardless of the night / day.

The soil measurement sensor module measures the soil information inside the green house 100 and the Co2 measurement sensor module measures the amount of Co2 inside the greenhouse 100.

At this time, soil information means soil nutrient condition, water content and geothermal temperature (soil temperature).

The ultrasonic sensor module is configured to measure the amount of snowfall on the upper outer surface of the greenhouse 100, and specifically configured as shown in FIG. 3 of the accompanying drawings.

FIG. 3 shows an example in which a soil measurement sensor module is configured in a smart green house control system according to the present invention.

As shown in FIG. 3A, the ultrasonic sensor module is installed to have a height of 15 cm from the uppermost side of the green house 100, and is designed to look at a distance of 30 cm from the installation point. The snow height determination unit may further include a height determination unit that determines a snow height of the snow.

The algorithm for determining the snow height by the snow height determination unit is as follows.

First, according to Pythagoras theorem, the measurement angle of the ultrasonic sensor module is calculated as follows and is set to 60 degrees.

)는,

Angle(

),

3 (b), the z value described in Fig. 3 (b) becomes 2 according to cos (60 deg.) If an object of 1 cm height is placed on the upper outer surface of the vinyl (Fig.

Therefore, the following expression is established.

In this case, the height is assumed to be 1 cm in Equation (2), but it can be proposed as Equation (3), assuming that the actual snow height is y.

Now, calculating the measurement value V based on Equation (3) yields Equation (4), so that it is possible to determine the snowfall height of the actual snow.

In other words, V means snow height, and z means a range corresponding to a snow-covered portion of the total sensing range of the ultrasonic sensor module (see FIG. 3 (b)).

The controller 190 controls the fan unit 130, the opening and closing unit 140, the snow remover 150, the absorber 160, and the Co2 feeder 170 (described later) according to the sensor value measured by the sensor unit 180 ), And includes a fan device control module, an opening / closing device control module, a snow removal device control module, a fluids control module, and a Co2 control module.

The controller 190 is based on Actuator control and Arduino technology. Although not shown in the accompanying drawings, the controller 190 can implement a MySQL database based on Raspberry pie for information storage.

First, the snow removal apparatus control module controls the snow removal apparatus 150 to operate when the snow height determined by the ultrasonic sensor module is not less than a predetermined value (for example, 2 cm).

The fluid controller control module controls the operation of the fluid controller 160 so that the nutrient solution is supplied to the soil inside the green housing 100 according to the nutrient condition, the moisture content and the temperature of the soil (ground temperature) of the soil measured by the soil sensor module. As shown in FIG.

When the amount of Co2 inside the greenhouse 100 measured by the Co2 measuring sensor module is less than the level required for plant growth, the Co2 feeder control module controls the Co2 feeder 170 so that Co2 (carbon dioxide) To be supplied to the inside.

The fan device control module and the opening / closing device control module control the fan device 130 and the opening / closing device 140 based on the measured values of the temperature / humidity sensor module to perform the function of making temperature and humidity suitable for plant growth . The level at which the temperature or humidity is suitable for plant growth may refer to the description given above.

The fan unit control module and the opening and closing device control module can close the green house 100 through the opening and closing device if the temperature inside the greenhouse 100 is proper, The greenhouse 100 is opened so that the greenhouse 100 is connected to the outside, and when the temperature exceeds the predetermined temperature, the fan unit 130 is operated in a state where the greenhouse 100 is closed, The temperature can be reduced through the discharge of air.

In the present invention, the sensor unit 180 may further include a sensor for measuring the amount of sunshine and an air flow rate sensor, so that the temperature / humidity can be maintained more effectively.

At this time, although not shown in the accompanying drawings, it is enough to measure the amount of sunshine and the amount of air outside the greenhouse 100, for example, a sunshine measurement sensor and an airflow measuring sensor.

The present invention can be operated as follows in accordance with the sunlight measuring sensor and the airflow measuring sensor.

end. If the temperature inside the Greenhouse exceeds the proper temperature

(a) When the amount of sunshine is equal to or lower than the appropriate level (50 Lux) and the amount of air is at an appropriate level (for example, 10 m ² / s) or less,

(b) If the amount of sunshine is at or below a suitable level and the amount of wind exceeds the appropriate level, the plant is affected by wind in plant cultivation, so that the fan unit 130 is controlled to be driven

(c) When the amount of sunshine exceeds an appropriate level, only the opening / closing device 140 is controlled to be driven

This is because the internal temperature of the greenhouse 100 exceeds the proper temperature and the greenhouse 100 is closed to completely shut off the connection to the outside, At the same time, it is possible to make the plants grow in a nature-friendly manner, to judge the amount of sunshine, and to be able to appropriately sunlight to have a better effect to be useful for plant growth.

I. If the temperature inside the Greenhouse is below the proper temperature

(a) When the amount of sunshine is equal to or lower than the appropriate level (50 Lux) and the amount of air is at an appropriate level (for example, 10 m ² / s) or less,

(b) When the amount of sunshine is at or below a proper level and the airflow rate exceeds the proper level, only the fan unit 130 is controlled to be driven

(c) When the amount of sunshine exceeds an appropriate level and the air volume is at an appropriate level or less,

(d) when the amount of sunshine exceeds a suitable level and the amount of air exceeds the proper level, only the fan unit 130 is controlled to be driven

This is because if the temperature inside the greenhouse 100 is lower than the proper temperature and the opening and closing device 140 is opened, if the amount of air outside the greenhouse 100 is exceeded and the amount of wind is too high and / So that ultraviolet rays generated by the sunlight are too strong to adversely affect plant growth. However,

It is expected that it will have a better effect to prevent the above-mentioned points because it is driven in consideration of the amount of sunshine and the amount of air.

1 and 3 are merely the main points of the present invention, and the present invention is not limited to the configurations shown in Figs. 1 and 3, as various designs can be made within the technical scope thereof. It is self-evident.
