Problems solved by technology

However, if the sun is fully used during the day, when the temperature is high in summer, the direct sunlight is easy to sunburn the crops.
Moreover, due to the shading of various facilities in the greenhouse and the continuous movement of the sun, it is easy to cause the crops to receive inconsistent light, and the growth speed of the crops will also be inconsistent; it will increase the cost of management

Embodiment 1

[0039] An intelligent supplementary light device for seedling cultivation in this embodiment includes a sunlight shading module, a control module, an artificial light source module, and a data acquisition module.

[0040] Such as figure 1 and figure 2 As shown, in this embodiment, the top of the greenhouse 1 is arc-shaped, and the axis of the top of the greenhouse 1 is used as the dividing line to divide the top of the greenhouse 1 into two symmetrical parts on the left and right, and each part is divided into several areas respectively. The division of the top area can be carried out according to the actual situation. For the convenience of management, it is sufficient to ensure that the left and right areas are symmetrical about the dividing line. The crops planted in the greenhouse 1 are divided according to the orthographic projection of the top area of ​​the greenhouse 1. In other words, the division of the crop area and the division of the top area of ​​the greenhouse ...

Embodiment 2

[0056] The difference between this embodiment and Embodiment 1 is that this embodiment also includes an image acquisition module, and the image acquisition module includes several cameras, and the cameras are used to collect images of crops every preset time. The preset time is 12-24 hours. 12 hours were used in this example. Each area corresponds to at least one camera, and the camera is used to collect images of crops in the corresponding area. When setting up the camera, it should be ensured that the leaves of the crops are clearly visible in the images captured by the camera.

[0057] The storage unit pre-stores crop growth cycle and light intensity demand data, crop leaf area and growth cycle data.

[0058] The processing unit is used to acquire the light intensity data of each area from the illumination sensor, and the image of the crops in each area from the camera; the processing unit calculates the current growth cycle of the crops in each area based on the images o...

Embodiment 3

[0063] The difference between this embodiment and Embodiment 1 is that, if image 3 and Figure 4 As shown, it also includes a solar module and a ventilation module; the solar module includes a frame 7 , a rotating mechanism 8 and a solar panel 9 .

[0064] The lower end of the frame 7 is connected with the top of the greenhouse 1 by bolts; specifically, the frame 7 is located in the middle of the two shutter machines 2 at the top of the greenhouse 1; the upper end of the frame 7 is connected with the lower end of the rotating mechanism 8 by bolts; Solar panel 9-bolt connection. In this embodiment, the rotating mechanism 8 includes a servo motor and a harmonic reducer, the output shaft of the servo motor is connected to the input shaft of the harmonic reducer by bolts, and the output shaft of the harmonic reducer is connected to the solar panel 9 by bolts; in other In the embodiment, other rotating mechanisms 8 may also be used to realize the rotating function of the solar b...

Abstract

The invention relates to the technical field of agricultural seedling raising, in particular to an intelligent light supplementing device for seedling raising, which comprises a sunlight shielding module and a control module, wherein the sunlight shielding module comprises a rolling blinds machine and a sun-shading film, the rolling blinds machine is fixed at the top of a greenhouse, and is used for rolling up or releasing the sun-shading film; and the control module is used for controlling the rolling blinds machine to perform rolling or releasing actions and recording the current rolling orreleasing state of the sun-shading film. The device further comprises an artificial light source module and a data acquisition module, wherein the artificial light source module comprises a pluralityof light supplementing lamps, and the light supplementing lamps are used for providing artificial illumination; the data acquisition module comprises an indoor acquisition unit used for acquiring internal illumination intensity; the control module is used for acquiring internal illumination intensity; and when the internal light intensity is lower than the first threshold value, the sun-shading film is in a released state, and the control module is further used for controlling the rolling blinds machine to perform rolling action. By adopting the technical scheme, the growth speed of crops canbe ensured to be consistent.

Description

technical field [0001] The invention relates to the technical field of agricultural seedling cultivation, in particular to an intelligent supplementary light device for seedling cultivation. Background technique [0002] Intelligent crop seedling cultivation has the advantages of large scale, labor-saving and cost-saving, and good benefits. It can provide important guarantees for the introduction, testing, demonstration, promotion of excellent new varieties, and increase the breeding rate. It can also save land resources and ensure the quality of seedlings. Has great development prospects. [0003] At present, the method of raising seedlings in greenhouses is generally adopted. However, the growth of crops is inseparable from sufficient light, and the light conditions in the greenhouse directly affect the growth and development, yield and quality of crops. At present, greenhouse seedlings mainly rely on artificial light sources to provide light. However, in the daytime, a...
