Description

FIELD OF THE INVENTION [0001] The present invention relates to a method and apparatus for daylight management for location-based plant cultivation,

The present invention relates to a method and apparatus for daylight management for location-based plant cultivation that controls the use of supplementary light according to the sunrise / sunset time information, the solar radiation amount, and the irradiation time of the present location in accordance with the optical property information of cultivated plants will be.

Generally, it is important to artificially cultivate the natural plant growth environment in the cultivation facilities such as the house and to establish the solar environment in order to cultivate the plant all year regardless of seasonal and external environment changes. This is because it induces photosynthesis, which is a direct growth factor for plant growth.

In order to cultivate tropical and subtropical plants (long hours of light hours are known as 13 hours and 30 minutes to 14 hours) in the environment of our country, especially in the short winter season (long days between November and February) 10 hours), there are many environmental factors to overcome.

One of them is a shortage of time, which causes lack of photosynthesis which is essential for the growth of the plants, which may lead to deterioration of the growth of the plants, which may lead to extension of the cultivation period and quality deterioration.

Therefore, in order to solve the insufficient solar radiation problem, a method of inducing photosynthesis with an artificial light source by installing a light source in a cultivation facility has been attempted.

However, since the conventional light control system of this type is made by manual operation of the user as an on / off operation of a simple light control using a timer, it is impossible to confirm whether or not a long time is appropriate or not, There was a problem.

In addition, when insufficient or excessive amount of light-shielding time did not meet the optical characteristics of each cultivated plant, stress of the plant could be induced and the environment optimized for growth of each plant could not be created. .

In order to prevent deterioration of the quality of cultivated plants and to save energy, it is important to choose a supplemental technique that is suitable for the optical characteristics of cultivated plants.

The controller 200 is installed in a cultivation facility such as a house and performs a programmable logic controller (PLC) function. (For example, the reference origin of the latitude and longitude of the Republic of Korea is Suwon National Geographical Survey Institute, latitude 37 ° 16'31.9034 "and east longitude 127 ° 03'05.1415"). (For example, information on the optical characteristics of each cultivated plant (for example, information on growth of light compensation points, light saturation points, long days of time, etc.) Optical method, light interruption method, intermittent method, etc.) are stored in advance. The information may be manually updated by the user performing the management, or updated via a network such as the Internet.

In addition, the controller 200 checks the latitude and longitude of the currently installed area, and then, based on the latitude and longitude of the current location and the reference origin, based on the sunrise / The sunrise / sunset time to be changed is corrected and calculated. Then, based on the data measured by the sensor 100, the solar radiation amount detection and light irradiation time integration are performed, and a long time, a solar radiation amount, and a light irradiation time integrated value by the sunrise / sunset time of the current position and date are stored And the sunrise / sunset time, the solar radiation amount, and the light irradiation time integrated value of the current date are compared with the optical property information of the plant being planted, and it is confirmed whether or not the growth conditions based on the optical property information of the plant being cultivated. Based on the comparison result, one of the operation modes for daylight management is set, and the light-blocking lamp 300 is turned on or blocked according to the set operation mode.

At this time, the preconditioning method among the above-described operation modes is an operation mode in which light is turned on during the daytime when the amount of insolation is insufficient after sunrise. Based on the optical property information of the plant being cultivated in which the insolation amount per unit time detected by the controller 200 is stored If it is determined that the amount of radiation is less than one light compensation point, the light 300 is turned on, and if the light amount per unit time exceeds the predetermined light compensation point after the light 300 is turned on, The controller 300 turns off the illumination of the light source 300 during a predetermined period of time based on the optical characteristic information of the cultivating plant stored for a long time after the sunset. The precursor method can be applied to all cultivated plants such as fruit vegetables, leafy vegetables, and the like.

The light interruption method can be applied to fruits and vegetables (especially cut flowers such as chrysanthemums and roses).

In the operation mode, the intermittent method is a driving mode in which the lighting of the light source 300 is repeated for several minutes to several tens of minutes at regular intervals of the night time zone, and is a method used for promoting the flowering of cut flowers.

It is preferable that the light-collecting light 300 is formed of a light emitting diode (LED). In addition, all products currently available on the market such as incandescent lamp, halogen lamp, sodium lamp, And turns on or off based on the control signal.

The shielding film 400 is provided on the upper and side surfaces of the cultivation facility and is operated by a control signal input from the controller 200 to perform light shielding.

At this time, when the barrier 400 is applied to the cultivation facility, the controller 200 controls the amount of irradiation based on the optical property information of the cultivated plant in which the irradiation amount and the irradiation time have been stored since the sunrise, And an operation mode in which light irradiation is cut off by driving it may be additionally applied.

In addition, the cultivation facility may be divided into plants for each of the cultivated plants. In this case, the controller 200 may apply the operation modes depending on the plant cultivated for each compartment.

The location confirmation unit 210 confirms the latitude and longitude of the area where the controller 200 is currently located through the GPS (Global Positioning System).

The storage unit 220 stores each operation mode information according to the growing conditions based on the sunrise / sunset time information on the reference origin of each country, the optical characteristic information of cultivated plants, and the optical characteristic information of cultivated plants.

The operation / display unit 230 is constituted by a conventional touch panel or the like and receives an operation signal for daylight management and receives a current operation state of the controller 200 (for example, an operation mode in operation, , The amount of solar radiation, whether it is in normal operation, etc.).

The communication unit 240 is electrically connected to the plurality of sensors 100 to receive measurement values related to the irradiation amount, and transmits a control signal related to lighting by the auxiliary light 300.

The controller 250 controls the current position determination in the position check unit 210 and changes the latitude and the longitude determined by the position check unit 210 and the latitude and longitude deviation of the reference origin stored in the storage unit 220 And performs real-time integration of the irradiation time and detection of the irradiation amount based on the measurement value input from the sensor 100 through the communication unit 240. [ Then, it is checked whether the growth condition is satisfied or not by comparing the current solar irradiation amount and the light irradiation time integrated value for a long time according to the current position with the optical property information of the currently cultivated plant stored in the storage unit 220, To control the setting of the operation mode for daylight management and lighting or light interruption of the complementary light depending on the set operation mode.

FIGS. 4 and 5 are flowcharts illustrating an operation of a daylight management method for location-based plant cultivation according to an exemplary embodiment of the present invention.

First, the controller 200 installed in the cultivation facility extracts the sunrise / sunset time that changes according to the latitude and the longitude deviation of the current location and the reference origin, based on the sunrise / sunset time of each day at the reference origin (S100).

5, the controller 200 checks the latitude, longitude, and sunrise / sunset time of the reference origin stored in each country (S110) The current date is confirmed through the RTC (Real Time Clock), and the latitude and longitude of the current position are confirmed through GPS (S120).

The controller 200 checks the deviation between the latitude and longitude of the current position and the latitude and longitude of the reference origin in step S110 in step S120 and determines whether the reference origin in each country / Sunset time, and corrects and extracts the sunrise / sunset time of the current position at the current position according to the latitude and the longitude deviation with respect to the reference origin identified in step S130 (S140).

After correcting and extracting the sunrise / sunset time in the current latitude and longitude through step S100, the controller 200 calculates the solar radiation amount and the light irradiation time integration based on the measurement value of the sensor 100 provided in the cultivation facility (S200).

The controller 200 compares the solar radiation amount and the light irradiation time integrated value performed in step S200 with the optical property information of the currently cultivated plant for a long time by the sunrise / sunset time of the current date extracted in step S100 , The sunrise / sunset time of the current date, the solar radiation amount, and the light irradiation time integrated value satisfy the growth condition based on the optical characteristic information of the plant being cultivated (S300). That is, whether or not the current integrated amount of irradiation and light irradiation time measured by the sensor 100 is appropriate when comparing with the growth conditions of the corresponding plant including the light compensation point, the light saturation point, and one day.

Thereafter, the controller 200 sets an operation mode for daylight management based on the comparison result in step S300 (S400). That is, one of the rolling method, the light compensation method, the optical stop method, and the intermittent method.

In this case, the rolling method is a driving mode in which the light is turned on during the daytime when the solar radiation is insufficient after the sunrise, and the light compensation method is a driving mode in which the light is turned on during a long time short after the sunset. The intermittent operation mode is an operation mode in which the lighting of the auxiliary lamp is repeated for several minutes to several tens of minutes at regular intervals of the night time period.

After setting the operation mode through step S400, the controller 200 lights or blocks the light 300 according to the operation mode (S500).

Accordingly, according to the present invention, it is possible to calculate a long day of a day by automatically calculating the sunrise / sunset time according to the installed position of the equipment, and automatically set the light-emitting time based on the accumulation and integration of the current daytime progress time, The daytime and nighttime lighting time can be optimized by promoting photosynthesis by daytime lighting or by tracking the daytime radiation environment when the light is insufficient after sunrise. When the limit temperature is reached, the supplementary light is turned off, and the heating temperature at night can be automatically set by prediction of the daily photosynthesis amount.

In addition, the present invention can prevent the increase of the power ratio due to overuse of the supplementary light, etc., and can reduce the maximum power consumption by dispersion of the power consumption peak value when the sequential lighting method such as complementary light is applied. Management can be performed. In addition, it is possible to optimize the supplementary environment for each cultivated plant and growth environment, thereby improving the quality of the product and shortening the cultivation period. Also, it is possible to control the flowering time by controlling the growth cycle of cultivated plants, And the income of the grower can be increased.
