Description

Technical Field

[0001] This application relates to the technical field of orchard lighting control, and specifically relates to an orchard lighting control system and method. Background Art

[0002] As is well known, whether the natural light is sufficient determines the quality of loquat fruits in the orchard. However, natural light is affected by factors such as seasonal changes, weather conditions, and orchard planting density, and thus it is impossible to guarantee the quality of loquat fruits in the orchard. The problem of uncontrollable quality of loquat fruits brought 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, this application proposes an orchard lighting control system and method.

[0003] The prior art, such as an invention application patent with the publication number CN115812477A, discloses a lighting control method and lighting control system for a three-dimensional cultivation greenhouse. By using the lighting data required during the growth cycle, a first scheduling plan is formulated for the seedbed units, the positions and light-receiving times of each seedbed unit are controlled, and the lighting intensity is monitored in real time through a sensing unit to feedback and adjust the first scheduling plan. Then, a second or third scheduling plan is generated according to the actual light-receiving amount, and the seedbed units are supplemented with light by 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 considers the light-receiving situation of the seedbed units in the non-light-facing positions, so as to achieve the purpose of accurately controlling the actual light-receiving amount of each seedbed.

[0004] For the above-mentioned solution, there are at least the following technical problems: 1. The current technology lacks the analysis of natural light, which leads to the fact that most of the current supplementary lighting technologies are aimed at the middle and lower parts and the inner cavities of the tree crown, without considering that when the natural light is insufficient, the loquat fruits at the top of the tree crown also need to be supplemented with light. The neglect of this aspect in the prior art will result in an unsatisfactory supplementary lighting effect, and thus it is impossible to maximize the quality and benefits of loquat fruits.

[0005] 2. The current technology does not perform supplementary lighting treatment according to the needs of users. When users have different emphases on the quality and taste of loquat fruits, selecting different supplementary lighting types for targeted supplementary lighting can improve the user's consumption experience, and at the same time can ensure the diversity of loquat fruits in the orchard, thereby expanding the sales market. The neglect of this aspect in the current technology leads to a single quality of loquat fruits in the orchard, which cannot meet the taste requirements of different users, and at the same time indicates that the current technology lacks rationality and perfection. Summary of the Invention

[0006] The purpose of this application is to provide an orchard lighting control system and method, which solves the problems existing in the background art.

[0007] To solve the above technical problems, the present application adopts the following technical solutions: In the first aspect, the present application provides an orchard lighting control system, including: a natural light analysis module, a supplementary lighting test module, a supplementary lighting confirmation module, and a display terminal.

Among them, "T1" is the control group, and "T2", "T3" and "T4" are the test groups. Set the T1 group that the strongly illuminated loquat fruits do not receive artificial supplementary lighting, the T2 group that the weakly illuminated loquat fruits receive supplementary lighting of "red light + full spectrum" and "red light + blue-violet light", the T3 group that the weakly illuminated loquat fruits receive supplementary lighting of "red light + full spectrum", and the T4 group that the weakly illuminated loquat fruits do not receive supplementary lighting.

[0018] S4. Conduct a pulp taste test on the collected loquat fruit samples of each group and record the test results. After the recording is completed, the test ends.

[0019] Preferably, the pulp quality test and the pulp taste test are carried out, and the specific test process is as follows: A1. Immediately transport the loquat fruit samples of each group to the laboratory after harvesting, set the laboratory environment to be constant, use a vernier caliper to measure the pulp thickness and the single fruit transverse diameter of the loquat fruit samples of each group, then use an electronic balance to measure the single fruit mass of the loquat fruit samples of each group, and finally separate the pulp, peel and pit and measure the masses of the pulp, peel and pit respectively, record the measurement results, and based on the above measurement results, analyze and obtain the edible rate of the loquat fruit samples of each group.

[0020] A2. Measure the soluble solids of the loquat fruit samples of each group based on a PAL-1 digital refractometer, and then measure the acidity pH after squeezing the juice from the pulp, record the measurement results, and based on the above measurement results, analyze and obtain the sweetness index of the loquat fruit samples of each group. After the analysis is completed, the test ends.

[0021] Preferably, the influence of supplementary lighting or not and the type of supplementary lighting on the quality of loquat fruits is analyzed as follows: C1. Based on the pulp quality test, obtain the single fruit mass of the loquat fruit samples of each group. Use the group numbers as the abscissa and the single fruit mass of the loquat fruit samples of each group as the ordinate to establish a single fruit mass comparison chart, and obtain the pulp mass, peel mass and pit mass of the loquat fruit samples of each group respectively to establish a single fruit different component mass distribution ratio chart.

[0022] C2. Obtain the single-fruit transverse diameter of each group of loquat fruit samples based on the pulp quality test. Use the group numbers as the abscissa and the single-fruit transverse diameters of each group of loquat fruit samples as the ordinate to establish a single-fruit transverse diameter comparison chart. Similarly, establish a pulp thickness comparison chart, a ratio comparison chart of pulp thickness to single-fruit transverse diameter, and an edible rate comparison chart respectively.

[0023] C3. Obtain the soluble solid content of each group of loquat fruit samples based on the pulp taste test. Use the group numbers as the abscissa and the soluble solid contents of each group of loquat fruit samples as the ordinate to establish a soluble solid content comparison chart. Similarly, establish an acidity pH comparison chart.

When supplementary lighting has an impact on loquat fruits, obtain the test group with the largest edible rate based on the pulp quality test and record it as the loquat fruit quality group.

[0025] C5.

[0026] Preferably, according to the analysis results of the supplementary lighting test and the user's quality requirements for loquat fruits, supplement light to the weakly lit loquat fruits. The specific supplementary lighting process is as follows: When the user's quality requirement for loquat fruits is higher than the taste requirement, obtain the supplementary lighting type of the loquat fruit quality group and supplement light to each weakly lit loquat fruit; when the user's taste requirement for loquat fruits is higher than the quality requirement, obtain the supplementary lighting type of the loquat fruit taste group and supplement light to each weakly lit loquat fruit; when the user has requirements for both the quality and taste of loquat fruits, obtain the supplementary lighting type of the best lighting group and supplement light to each weakly lit loquat fruit.

[0033] 3. By performing fill light tests on various types of loquat fruits, the present application further analyzes the effects of fill light or not and fill light types on the quality of loquat fruits, providing a basis for subsequent fill light of each loquat fruit with weak light in the orchard, ensuring the rationality and perfection of the orchard lighting control system, solving the problem of quality decline of each loquat fruit with weak light caused by insufficient received light, and also solving the problem that each loquat fruit with weak light cannot grow and develop normally due to too high planting density, greatly improving the quality of loquat fruits in the orchard, thereby improving its market competitiveness, and thus ensuring the sales volume of the loquat fruits in the orchard, bringing higher economic benefits to the orchard.

[0034] 4.

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

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

[0043] Natural light analysis module: used to classify each loquat fruit on the loquat tree according to natural light information, and then obtain each weakly illuminated loquat fruit and each strongly illuminated loquat fruit.

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

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

[0046] Obtain the light intensity Q of each loquat fruit in the orchard at each unit time within 24 hours based on natural light information iv , combining the light intensity and light stability index of each loquat fruit, according to the calculation formula: Analyze to obtain the natural light index of each loquat fruit where i represents the number of each loquat fruit, i = 1, 2,......n, n represents the total number of loquat fruits, v represents the number of each unit time within 24 hours, v = 1, 2,......y, y is an integer greater than 2, and y represents the total number of unit times within 24 hours.

[0047] Compare the natural light index of each loquat fruit with the standard value of the natural light index of the loquat fruit. When the natural light index of a certain loquat fruit is greater than or equal to the standard value of the natural light index of the loquat fruit, mark this loquat fruit as a strongly illuminated loquat fruit; otherwise, mark this loquat fruit as a weakly illuminated loquat fruit. Based on this, obtain each strongly illuminated loquat fruit and each weakly illuminated loquat fruit.

[0048] It should be noted that obtain the maximum value of the natural light index of each loquat fruit tree within 24 hours, and take the average value of the maximum values of the natural light index as the standard value of the natural light index of the loquat fruit.

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

[0050] In a specific example, the analysis to obtain the light stability index of each loquat fruit is as follows: Combine the light duration W of each loquat fruit within 24 hours i and the light area S at each unit time within 24 hours iv , according to the calculation formula Analyze to obtain the light stability index F of each loquat fruit i , where W′ and S′ respectively represent the standard value of the light duration and the standard value of the light area of the loquat fruit, and τ1 and τ2 respectively represent the weight factor corresponding to the light duration of the loquat fruit and the weight factor corresponding to the light area of the loquat fruit.

[0051] It should be noted that the standard value of the light duration of the loquat fruit is the average value of the light duration of the loquat fruits with the longest light duration within 24 hours on each loquat fruit tree; the standard value of the light area is the average value of the light areas of the loquat fruits with the largest light area within 24 hours on each loquat fruit tree.

[0052] It should be noted that 0 < τ1 < 1, 0 < τ2 < 1, and τ1 + τ2 = 1.

[0053] It should be noted that the weight factors corresponding to the light duration and the weight factors corresponding to the light area of loquat fruits are obtained through factor analysis. First, the information concentration of the spatial path attenuation of the light duration and the light area of each loquat fruit is carried out, and then the variance interpretation rate after rotation is obtained. The weight is obtained by dividing the cumulative variance interpretation rate.

[0054] It should be noted that factor analysis is a well-known technology. It is a multivariate statistical analysis method that starts from the study of the internal correlation and dependence relationship of variables and reduces a number of variables with complex relationships into a few comprehensive factors. Information concentration is expressed as calculating the median. The variance interpretation rate is the amount of information extracted by factors, and the variance interpretation rate = eigenvalue / total number of analysis items. The variance interpretation rate after rotation is expressed as the variance interpretation rate of factors after maximum variance rotation.

[0055] Supplementary light test module: used to conduct supplementary light tests on various types of loquat fruits, analyze the influence of supplementary light or not and the type of supplementary light on the quality of loquat fruits, and then obtain the optimal light group.

[0056] In a specific example, the process of conducting supplementary light tests on various types of loquat fruits is as follows: S1. Obtain a number of strongly illuminated loquat fruits and a number of weakly illuminated loquat fruits during the maturity period in the orchard, and set four groups of "T1", "T2", "T3" and "T4" for supplementary light tests based on natural light and artificial supplementary light. Among them, "T1" is the control group, and "T2", "T3" and "T4" are the test groups. Set the T1 group as the strongly illuminated loquat fruits without artificial supplementary light, the T2 group as the weakly illuminated loquat fruits with supplementary light of "red light + full spectrum" and "red light + blue-violet light", the T3 group as the weakly illuminated loquat fruits with supplementary light of "red light + full spectrum", and the T4 group as the weakly illuminated loquat fruits without supplementary light.

[0057] S2. Collect samples of loquat fruits in the light group after one week of natural light and samples of loquat fruits in each test group after one week of supplementary light.

[0058] S3. Conduct pulp quality tests on the collected samples of loquat fruits in each group and record the test results.

[0059] S4. Conduct pulp taste tests on the collected samples of loquat fruits in each group and record the test results. After the recording is completed, the test ends.

[0060] It should be noted that the purpose of this application is to analyze the influence of supplementary light or not and the type of supplementary light on the quality of loquat fruits. The type of supplementary light in the test group can be set by relevant staff, which can be "red light + full spectrum" and "red light + blue-violet light", or "red light + full spectrum", or "blue-violet light + full spectrum". Therefore, it should not be understood as a limitation to this application.

[0061] It should be noted that the collected loquat fruit samples in each group should have the same maturity, size, no mechanical damage, and no pests and diseases.

[0062] In a specific example, the pulp quality test and the pulp taste test are carried out. The specific test process is as follows: A1. Immediately transport the loquat fruit samples in each group to the laboratory after harvesting. Set the laboratory environment to be constant. Use a vernier caliper to measure the pulp thickness and the single fruit transverse diameter of the loquat fruit samples in each group, and then use an electronic balance to measure the single fruit mass of the loquat fruit samples in each group. Finally, separate the pulp, peel, and pit, and measure the masses of the pulp, peel, and pit respectively, record the measurement results, and based on the above measurement results, analyze and obtain the edible rate of the loquat fruit samples in each group.

[0063] A2. Measure the soluble solids of the loquat fruit samples in each group based on a PAL-1 digital refractometer. Then, squeeze out the juice from the pulp and measure the acidity pH. Record the measurement results, and based on the above measurement results, analyze and obtain the sweetness index of the loquat fruit samples in each group. After the analysis is completed, the test ends.

[0064] It should be noted that the constant laboratory environment includes both constant temperature and humidity. For example, set the temperature to 27°C and the humidity to 40RH.

[0065] In a specific example, the edible rate and the sweetness index of the loquat fruit samples in each group are analyzed. The specific analysis process is as follows: Denote the single fruit mass, the mass of the peel, and the mass of the pit of the loquat fruit samples in each group as M′ j , and According to the calculation formula: Analyze and obtain the edible rate β j of the loquat fruit samples in each group, where j represents the group number, j = T1, T2, T3, T4.

[0066] Denote the soluble solids and the acidity pH of the loquat fruit samples in each group as R j and P j , respectively. According to the calculation formula Analyze and obtain the sweetness index χ j of the loquat fruit samples in each group, where μ1 and μ2 represent the weight factors of the soluble solids in the loquat fruit and the reciprocal of the acidity pH, respectively.

[0067] It should be noted that 0 < μ1 < 1, 0 < μ2 < 1, and μ1 + μ2 = 1.

[0068] It should be noted that by using factor analysis to obtain the weight factors corresponding to the soluble solids in loquat fruits and the weight factors corresponding to the reciprocal of the acidity pH, first, information condensation of the spatial path attenuation of the soluble solids and the reciprocal of the acidity pH in each loquat fruit is performed, and then the variance interpretation rate after rotation is obtained. The weight is obtained by dividing the cumulative variance interpretation rate.

[0069] In a specific example, the influence of whether to supplement light and the type of supplementary light on the quality of loquat fruits is analyzed as follows: C1. Based on the pulp quality test, the single fruit weight of each group of loquat fruit samples is obtained. Taking the group numbers as the abscissa and the single fruit weight of each group of loquat fruit samples as the ordinate, a single fruit weight comparison graph is established, and the pulp weight, peel weight, and seed weight of each group of loquat fruit samples are used to establish a graph of the mass distribution ratio of different components of a single fruit respectively.

[0070] C2. Based on the pulp quality test, the single fruit transverse diameter of each group of loquat fruit samples is obtained. Taking the group numbers as the abscissa and the single fruit transverse diameter of each group of loquat fruit samples as the ordinate, a single fruit transverse diameter comparison graph is established; similarly, a pulp thickness comparison graph, a ratio comparison graph of pulp thickness to single fruit transverse diameter, and an edible rate comparison graph are established respectively.

[0071] C3. Based on the pulp taste test, the soluble solid content of each group of loquat fruit samples is obtained. Taking the group numbers as the abscissa and the soluble solid content of each group of loquat fruit samples as the ordinate, a soluble solid content comparison graph is established; similarly, an acidity pH comparison graph is established.

[0072] C4. Based on the single fruit transverse diameter comparison graph, the pulp thickness comparison graph, the ratio comparison graph of pulp thickness to single fruit transverse diameter, and the edible rate comparison graph, if the single fruit transverse diameter, pulp thickness, ratio of pulp thickness to single fruit transverse diameter, or edible rate of the loquat fruit samples in group T2 and group T3 are different from those in group T1 and group T4, then it is analyzed that the supplementary light has an impact on the quality of loquat fruits; otherwise, it is analyzed that the supplementary light has no impact on the quality of loquat fruits; when the supplementary light has an impact on loquat fruits, based on the pulp quality test, the test group with the largest edible rate is obtained and recorded as the loquat fruit quality group.

[0073] C5. Based on the soluble solid comparison graph and the acidity pH comparison graph of each group of loquat fruit samples, if the soluble solids or acidity pH of the loquat fruit samples in group T2 and group T3 are different from those in group T1 and group T4, then it is analyzed that the supplementary light has an impact on loquat fruits, otherwise it is analyzed that the supplementary light has no impact on the taste of loquat fruits; when the supplementary light has an impact on loquat fruits, based on the pulp taste test, the test group with the largest sweetness index is obtained and recorded as the loquat fruit taste group.

[0074] In a specific example, the analysis to obtain the optimal light group is as follows: Comprehensively considering the edible rate β j and the sweetness index χj , according to the calculation formula , the quality index A of each group of loquat fruit samples is obtained through analysis j , the maximum value of the quality index of the loquat fruit samples of each test group except A is obtained, and the test group corresponding to the maximum value of the quality index is recorded as the optimal light group.

[0076] In a specific example, the process of supplementing light to loquat fruits with weak light according to the analysis results of the light supplement test and the user's quality requirements for loquat fruits is as follows: when the user's quality requirement for loquat fruits is higher than the taste, the light supplement type of the loquat fruit quality group is obtained to supplement light to each loquat fruit with weak light; when the user's taste requirement for loquat fruits is higher than the quality, the light supplement type of the loquat fruit taste group is obtained to supplement light to each loquat fruit with weak light; when the user has requirements for both the quality and taste of loquat fruits, the light supplement type of the optimal light group is obtained to supplement light to each loquat fruit with weak light.
