Abstract

The present invention relates to a lighting system for growing crops in a shaded area during solar power generation on an agricultural land, wherein a solar power module array is installed at a support structure installed at an upper portion of an agricultural land, and photosynthesis data are stored in a database to determine the photosynthesis state of each crop. Therefore, when the amount of carbon dioxide recognized by means of a carbon dioxide sensor and the level of illumination recognized by means of an inner illumination level sensor are recognized when the photosynthesis of the crops is actively performed, solar power generation performed by means of the solar power module is halted such that the solar power module may be opened in the same angle as the incidence angle of light. Furthermore, at least one light collecting unit is installed on the outside of the agricultural land to collect light, such that, when the light is being shone, the light delivered by means of a light transmission unit of a light cable may be divided for a shaded area, formed by the structure, by means of an inner light scattering unit. Resultantly, the crops are made to grow through active photosynthesis performed by the incident light without interference. Consequently, the present invention allows the crops to be harvested, and enables electricity production by means of solar power generation, while minimizing damage on the crops caused by the shaded area.

Description

Lighting system for growth crop in the shade area in the way of solar generation system in the farm land}

The present invention relates to a mining system for growing crops in shaded areas during photovoltaic power generation in agricultural land, and in particular, to install a photovoltaic module array on a support structure installed on top of farmland and to determine the photosynthesis state of each crop. When the photosynthesis data is stored in the database for the amount of carbon dioxide recognized by the carbon dioxide sensor and the illuminance recognized by the internal illuminance sensor as the photosynthesis of the crops is actively progressing, the photovoltaic power generation through the solar module array is stopped. The shade area is formed by the structure through the scattering part of the light transmitted through the optical transmission part of the optical cable during the mining by installing at least one condensing part for condensing on the outside of the farmland By spectrophotometrically In the agricultural land where the photosynthesis is activated by the incoming light without receiving the light, the crops are grown so that the crops can be harvested and the electricity is produced by photovoltaic power generation, and the damage of the crops by the shade can be minimized. The present invention relates to a mining system for growing crops in shaded areas during solar power generation.

In the past, a great deal of attention has been focused on a power generating system, and many solar modules are installed in structures such as a support structure of a house.

On the other hand, when constructing a solar photovoltatic power generating system (large photovoltatic power generating system) requires a large space for placing a number of modules (module).

Therefore, many agricultural lands exist in countries with a small area of land and many agricultural lands, such as Korea and Japan.

Thus, Korean Patent Registration No. 10-1274199 dated June 05, 2013 (Solar cell power plant with crop cultivation room and its construction method) was proposed.

It includes a greenhouse that is installed on the ground to form a greenhouse, and a solar cell structure coupled to the vertical support frame of the greenhouse,

The solar cell structure is one or more fans are installed on the surface facing north, thereby forming an air flow toward the solar cell module by the fan,

The solar cell structure is a structure for producing electricity from the solar light having a plurality of solar cell modules,

A plurality of solar cell modules;

It includes a support frame for supporting the solar cell module so that the light receiving surface of the solar cell module is substantially inclined toward the south,

The support frame portion is to be coupled to the vertical support frame of the greenhouse,

The support frame portion was configured to include a vertical frame that is supported and installed on the top of the vertical support frame of the greenhouse.

However, in the greenhouse equipped with the conventional photovoltaic power generation facilities as described above, while the photovoltaic module for photovoltaic power generation is installed on a part of the upper surface of the greenhouse, the light reflected by the natural light emitter is irradiated to the shade of the bottom. However, there is an inefficient problem in that photovoltaic power generation by a part of the greenhouse cannot generate enough electricity, so that the cost according to the photovoltaic facility is hardly recovered.

In addition, the solar module for photovoltaic power generation is installed on the entire upper surface of the greenhouse, but the structure installed in the entire greenhouse has the advantage of generation of electricity due to the photovoltaic power generation, while the entire bottom is shaded. There was a problem that hardly occurs as a greenhouse function.

In addition, solar sharing has been proposed and implemented by providing solar panels in agricultural lands and also performing photovoltaic power generation while farming in agricultural lands.

That is, according to Japanese Patent Laid-Open No. 2015-17489, a farm photovoltaic power generating system in which a solar photovoltaic power generating system is installed in agricultural land is described.

In this farm and solar photovoltaic power generating system, a plurality of pillars installed in commercial plants and a plurality of solar modules supported in an oblique manner to girders and girders growing horizontally from the top of the pillars are supported. Equipped with.

With this solar photovoltatic power generating system, the angle of inclination of the photovoltaic module with respect to the horizontal plane is predetermined and fixed at 10 ° to 15 ° with respect to the horizontal plane.

Therefore, since the angle of inclination of the panel is fixed in the above farm and solar photovoltaic power generating system, when the types of crops or the amount of insolation of cropland are changed, it is not possible to flexibly cope. When the photovoltaic module is installed in the upper part of the cropland, if the number of photovoltaic modules to be installed is too large, in order for the crops of the cropland not to be sufficiently lighted, the growth of the crop is not sufficient and the yield of the crop is reduced. You can think of it.

On the other hand, if the number of panels arranged in consideration of the growth of the crop is limited, there is a problem that it is not possible to sufficiently secure the amount of power generated by the panel does not affect the growth of the crop.

Thus, Japanese Patent Publication No. 27065387 (packaging management device and package management system) dated April 09, 2015 was proposed.

In order to acquire the illuminance of the light irradiated to the plant, an illuminance sensor is further provided in a space below the photovoltaic panel to change the posture when the illuminance of the light irradiated to the plant is greater than the reference illuminance. The posture of the photovoltaic panel is changed to increase the light receiving amount of the photovoltaic panel, and when the illuminance of light irradiated to the plant is equal to the reference illuminance, The posture is maintained, and when the illuminance of the light irradiated onto the plant is smaller than the reference illuminance, the posture of the photovoltaic panel is changed so that the light receiving amount of the photovoltaic panel is reduced.

In addition, Japanese Patent Publication No. 29012007 (solar power generation system) of January 19, 2017 was proposed.

The solar panel is installed on the upper part of the farmland,

Is provided with an angle changing unit for changing the inclination angle of the light receiving surface of the solar panel with respect to the incident direction of the sunlight,

The angle changing unit is configured to change the inclination angle so that the inclination angle approaches a right angle when the insolation amount of sunlight obtained by the insolation amount acquisition unit is equal to or greater than the light saturation point stored by the light saturation point storage unit.

In addition, Japanese Patent Publication No. 29145565 (Photovoltaic Power Generation System and Method) dated August 24, 2017,

While the position and / or inclination of the photovoltaic panel is dynamically changed so that the amount of solar radiation is maximum, when the cumulative solar radiation of the crop to the farmland exceeds the photosaturation point of the crop, the maximum amount of solar radiation to the photovoltaic panel is It was configured to change the tilt of the solar panel dynamically.

However, according to the structure and control method in which the photovoltaic module is installed on the conventional agricultural land as described above, it is not possible to confirm the state of photosynthesis accurately by measuring the light saturation point with illumination, and the photovoltaic power generation that prioritizes the growth of plants. This is not made can cause problems such as lowering the yield of crops, as well as the problem that the growth of plants in the area shaded by the solar module and the structure for the installation of the solar module is inhibited compared to other areas There was this.

Accordingly, the present invention is to solve the conventional problems as described above, by installing a photovoltaic module array in a support structure installed on the top of the farmland and storing photosynthetic data for determining the photosynthesis state of each crop in a database to carbon dioxide If the amount of carbon dioxide recognized by the sensor and the illuminance recognized by the internal illuminance sensor are recognized as the photosynthesis of the crops is actively progressing, the photovoltaic power generation through the solar module array is stopped and opened at the same angle as the incident angle of light. At least one condenser for condensing outside the farmland is installed so that the light transmitted through the optical transmission part of the optical cable is spectrally directed to the shade area formed by the structure through the scattering part inside, so that it is not disturbed at all.
