Description

Technical Field

[0001] The present application relates to the technical field of orchard lighting control, and in particular to an orchard lighting control system and method. Background Art

[0002] As we all know, whether there is sufficient natural light determines the quality of loquats in the orchard, but natural light will be affected by factors such as seasonal changes, weather conditions and orchard planting density, and thus the quality of loquats in the orchard cannot be guaranteed. The uncontrollable quality of loquats caused by natural light will also lead to a decrease in the economic benefits of the orchard, which is not conducive to the long-term development of the orchard. Therefore, the present application proposes an orchard lighting control system and method.

[0003] Prior art, such as the invention application patent with announcement number: CN115812477A, ​​discloses a lighting control method and lighting control system for a three-dimensional cultivation greenhouse. A first scheduling plan is formulated for the seedbed unit based on the lighting data required during the growth cycle, the position and light-receiving time of each seedbed unit is controlled, and the first scheduling plan is adjusted by real-time monitoring of the light intensity feedback through the sensor unit. A second or third scheduling plan is then generated based on the actual amount of light received, and the seedbed unit is supplemented with light using the remaining lighting data or a supplementary lighting system, so that the plants in the greenhouse receive light evenly during the growth cycle. When determining the scheduling plan, the present invention takes into account the light receiving conditions of the seedbed unit in a non-light-facing position, so as to achieve the purpose of accurately controlling the actual amount of light received by each seedbed.

[0004] With respect to the above scheme, there are at least the following technical problems: 1. The current technology lacks analysis of natural light, which results in the current supplementary lighting technology mostly targeting the middle and lower parts and inner chamber of the crown, without considering that when natural light is insufficient, the loquats at the top of the crown also need supplementary lighting. The existing technology's neglect of this aspect will lead to unsatisfactory supplementary lighting effects, and thus fail to maximize the quality and benefits of loquats.

[0005] 2. The current technology does not perform targeted fill-in lighting according to user needs. When users place different emphasis on the quality and taste of loquats, choosing different fill-in lighting types for targeted fill-in lighting can improve the user's consumption experience. At the same time, it can also ensure the diversity of loquats in the orchard, thereby expanding the sales market. The current technology's neglect of this aspect has led to the single quality of loquats in the orchard, which cannot meet the taste needs of different users. It also shows that the current technology lacks rationality and perfection. Summary of the invention

[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] Reference Figure 1 As shown, the present application provides an orchard lighting control system, comprising the following modules: a natural light analysis module, a fill light test module, a fill light confirmation module and a display terminal.

[0043] Natural light analysis module: used to classify the loquats on the loquat tree according to the natural light information, and then obtain the loquats with weak light and the loquats with strong light.

[0044] It should be noted that the natural light information includes the duration of natural light, the area of ​​light, and the intensity of light.

[0045] In a specific example, the classification of loquats according to natural light information is as follows: based on the natural light information, the light duration W of each loquat in the orchard within 24 hours is obtained. i And the illumination area S per unit time in 24 hours iv, and then analyze and obtain the light stability index F of each loquat fruit i .

When the natural light index of a loquat fruit is greater than or equal to the standard value of the natural light index of loquat, the loquat is recorded as a strong light loquat; otherwise, the loquat is recorded as a weak light loquat, thereby obtaining strong light loquats and weak light loquats.

[0048] It should be noted that the maximum values ​​of the natural light index on each loquat tree within 24 hours are obtained, and the average value of the maximum values ​​of the natural light index is used as the standard value of the natural light index of loquat.

[0049] It should be noted that the length of the unit time is set by the relevant staff and can be one hour, two hours, four hours, etc.

First, the information of spatial path attenuation of illumination duration and illumination area of ​​each loquat was condensed, and then the variance explanation rate after rotation was obtained, and the weight was obtained by dividing the cumulative variance explanation rate.

[0054] It should be noted that factor analysis is a well-known technology. It is a multivariate statistical analysis method that starts from studying the internal dependencies of variables and reduces some variables with intricate relationships to a few comprehensive factors; information concentration is expressed as calculating the median; the variance explanation rate is the amount of information extracted by the factor, and the variance explanation rate = characteristic root / total number of analysis items; the variance explanation rate after rotation is expressed as the variance explanation rate of the factor after maximum variance rotation.
