Description

Technical Field

[0001] The invention relates to an ultra-white rolled glass greenhouse light control system and a method thereof, belonging to the technical field of plant light supplementation. Background Art

[0002] Plants have five photochemical reactions, photosynthesis, pigment synthesis, photoperiod phenomenon, phototropism and photomorphogenic mutagenesis, all of which are concentrated in the range of 0.4-0.7μm. Solar radiation in the range of 0.4-0.7μm is usually called photosynthetically active radiation (PAR). Photosynthetically active radiation can be used by crop chloroplasts to carry out photosynthesis, converting inorganic matter into organic matter, converting solar energy into chemical energy, and storing it in organic matter. According to the law of photochemistry, the speed of photochemical reaction is determined by the amount of light absorbed. The photons that can be absorbed by photosynthesis are mainly photons within the photosynthetically active radiation spectrum.

[0003] In a glass greenhouse, the photosynthetic quantum density directly affects the growth, development, yield and product quality of crops. The comprehensive transmittance, photosynthetically active radiation (PAR) transmittance and haze of existing greenhouses using ordinary flat glass are relatively low, which will delay the growth of plants. At the same time, the total solar radiation transmittance is relatively high, which leads to a high temperature in the greenhouse and requires higher equipment energy consumption to cool down. At the same time, shadows will be generated in the greenhouse due to the shading of glass, structural parts and some equipment, which will affect the growth of plants. Although plant growth is mainly concentrated in the canopy, the middle and lower layers of plants also need to ensure sufficient light. A certain amount of scattered light and improved light utilization play a very important role in greenhouse control and growth stability guarantee under current extreme weather conditions. Therefore, it needs to be combined with fill light.

[0004] The current method of supplementary lighting for greenhouse crops is mainly to uniformly supplement the lighting for greenhouse crops through a light source with a fixed irradiation direction and fixed light intensity, including using a supplementary lighting device fixed on the top of the greenhouse to supplement the lighting for greenhouse crops, or using a supplementary lighting device placed horizontally between crop plants to supplement the lighting for greenhouse crops. However, the practice of using a fixed light source to uniformly supplement the lighting for greenhouse crops does not take into account the different lighting requirements of different plant parts of greenhouse crops. In addition, fixed artificial light sources may be blocked by leaves, causing uneven supplementary lighting and large supplementary lighting losses, resulting in poor supplementary lighting effects for greenhouse crops and inability to achieve precise supplementary lighting. Therefore, there is an urgent need for a glass greenhouse that can improve the comprehensive transmittance of light in the greenhouse, the transmittance of photosynthetically active radiation (PAR) and the haze, and can also provide precise supplementary lighting, and a system that can provide supplementary lighting in a timely manner according to job supplementary lighting needs. Summary of the invention

[0005] The technical problem to be solved by the present invention is that the comprehensive light transmittance, photosynthetically active radiation (PAR) transmittance and haze of the existing glass greenhouse using flat glass are relatively low, which will delay the growth of plants.

Multiple light sensors and temperature and humidity sensors are installed and arranged in the glass greenhouse 1 to ensure that the light data and temperature and humidity data at various locations in the glass greenhouse 1 can be monitored.

The provision of the spherical universal pan-tilt head 6 can facilitate the staff to make adaptive adjustments to the irradiation angle of the fill light according to the growth habits of the plants in the corresponding area, thereby improving the adaptability and practicality of the device. 2 is connected to the control system 4 by signal to automatically adjust the irradiation height of the fill light 323. The fill light 323 is connected to the control system 4 by signal to control the irradiation brightness and irradiation time of the fill light 323 to the area according to the existing light intensity data and temperature and humidity data at the required fill light ground.

The guide cylinder frame 3226 is fixedly installed on the latent robot 321 by bolts and is plugged and adapted with the guide column 3225, thereby guiding the sliding of the tripod 3224 and limiting the rotation of the tripod 3224 to avoid the possibility that the sliding cylinder frame 3223 drives the tripod 3224 to rotate together. Multiple fill lights 323 are rotatably installed on the tripod 3224 through the spherical universal pan-tilt head 6. The driving component 3227 is installed on the latent robot 321 and is connected to the control system signal for automatically driving the adjusting screw 3222 to rotate according to the light height to drive the tripod 3224 to an appropriate height.

[0040] Furthermore, the driving component 3227 includes a driving motor 322A, a first bevel gear 322B and a second bevel gear 322C.

[0041] Reference Figure 4 The present invention also provides a method for controlling light in an ultra-white rolled glass greenhouse, which uses the above-mentioned ultra-white rolled glass greenhouse light control system and comprises the following steps:

[0042] S1, confirming the plant varieties to be planted in each area of ​​the glass greenhouse 1;

[0043] S2, preset the light intensity and the minimum threshold of temperature and humidity corresponding to each area in the control system 4 according to the plant variety;

[0044] S3, start the greenhouse environment detection unit 2 and the supplementary light device 3, and connect the signals with the control system 4. Before operation, it is necessary to check that each light sensor and temperature and humidity sensor in the greenhouse environment detection unit 2 is connected with the control system 4.

[0045] When the fill light device 3 is started, it is ensured that the multiple groups of fixed fill light devices 31 are kept in a normally open state, so as to ensure that most areas in the glass greenhouse 1 are in a better lighting state.

[0046] S4, the greenhouse environment detection unit 2 detects that the light intensity or temperature and humidity at the target location is lower than the minimum threshold in the area, and transmits the signal to the control system 4. The control system 4 sends a control signal to control the mobile fill light device 32 in the area to fill light the target location with appropriate height and brightness for a certain period of time.

[0047] When multiple groups of mobile fill-light devices 32 do not receive a control signal, they all remain in an idle state; after receiving a control signal, the mobile fill-light devices 32 in the target area are started. Specifically, the control system 4 gives priority to filling light to the mobile fill-light device 32 closest to the target location in the target area. However, if there is an unexpected situation, such as: the mobile fill-light device 32 closest to the target location is performing a fill-light operation, then the one with sufficient margin, or the closest one among the idle ones, can be selected, and the other mobile fill-light devices 32 remain idle.

It should be pointed out that ordinary technicians in this technical field can make several improvements and supplements without departing from the present invention, and these improvements and supplements should also be regarded as the protection scope of the present invention.
