Description

Technical Field

[0001] The present invention relates to the technical field of laying hen breeding, and in particular to an intelligent LED light source control system for laying hen breeding. Background Art

[0002] Layer farming refers to the care and management of hens specifically designed for egg production. The egg-laying hen production cycle includes the brooding, rearing, and egg-laying periods. The main farming methods for laying hens include flat-laying, caged, and layered vertical farming. The goal is to ensure efficient and healthy egg production through scientific management, feeding, and lighting. As layer farming gradually develops towards large-scale, intensive, and intelligent farming, significant advances have been made in farming technology, including automated equipment, environmental control systems, and feed management. Lighting control technology, a key component, is also undergoing continuous innovation and upgrading.

[0003] Compared to traditional fluorescent and incandescent lamps, LED light sources offer longer lifespans, lower heat generation, softer light, higher energy efficiency, and lower power consumption, effectively saving operating costs. Furthermore, appropriate lighting can promote reproductive system development in laying hens, regulate hormone secretion, extend egg-laying periods, and improve eggshell quality and egg production. Different wavelengths of light have different effects on the behavior and physiology of laying hens. LED light sources can provide light of different wavelengths, such as red, blue, and green, and precisely adjust the spectrum to meet the needs of laying hens at different stages. LED light sources can also be combined with intelligent control systems to automatically adjust the duration, intensity, and spectrum of lighting, reducing manual intervention and optimizing breeding management.

[0004] Current LED light source control methods primarily include timed illumination control, dimming control, multispectral control, and intelligent sensor control. However, the predominant methods for raising laying hens are caged and stratified, resulting in high densities and high disease rates. The design of these cages can lead to uneven illumination between different layers, further contributing to low egg production rates. The present invention addresses the issue of how to monitor illumination uniformity and control and adjust illumination intensity during peak egg-laying periods to improve egg production efficiency.

[0053] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0054] Example 1

[0055] Lighting is an important environmental factor that affects laying hens' egg production. By properly controlling light intensity, we can effectively promote the sexual maturity of laying hens and maintain a high level of egg production, prolong the peak egg production period, improve egg quality, and enhance the health and welfare of laying hens. In order to improve the egg production rate of Hailan brown-shell laying hens, a laying hen farm introduced an intelligent LED light source control system for laying hen farming provided by the present invention to provide early warning and control of light intensity within the farm. The system structure is as follows: Figure 1 As shown, the specific implementation is as follows:

[0056] The light source monitoring module obtains the farm's circuit data and determines whether there is a fault. If there is a fault, it switches to the backup power supply;

[0057] Furthermore, the circuit data includes circuit data of all LED light sources in the farm. If the light source monitoring module detects that the power supply of the farm is unstable or a large-scale power outage occurs, the farm will be switched to a backup power supply to ensure the stability of the power supply to the farm.

[0058] The light intensity collection module includes a first collection point unit, a second collection point unit and a data collection unit. The first collection point unit selects a first light data collection point according to the cage position, and the second collection point unit selects a second light data collection point according to the movement trajectory of the laying hen. The data collection unit obtains the positions of the first light data collection point and the second light data collection point and collects light intensity to obtain light intensity data.

[0059] Furthermore, the first collection point unit includes:

[0060] The light source position and cage position of the farm are as follows: Figure 2 As shown, the structural layout of the laying hen farm is obtained and processed to obtain the position information of the cages, and the first illumination data collection points are selected in the center, four corners and edge areas of the cages according to the position information.

[0061] Furthermore, the overall structural layout of the laying hen farm is obtained through on-site surveys or by consulting design drawings. Next, based on the cage location information, the first light data collection points are set at multiple key locations within the cages. These key locations include, but are not limited to: the center of the cage, which is used to obtain the overall average level of light intensity within the cage; the four corners of the cage, which help assess the uniformity of light intensity; and the edge of the cage, which is often more susceptible to external environmental factors. Therefore, setting collection points can more accurately capture changes in light intensity.

[0062] Through this setting, the first collection point unit can comprehensively and accurately collect the lighting data of the cages in the laying hen farm, providing a solid data foundation for the subsequent analysis and optimization of lighting uniformity.

[0063] Furthermore, the second collection point unit includes:

[0064] A motion monitoring device is installed on the foot of each laying hen in the cage, and the motion monitoring device collects the motion data of the laying hen during the non-feeding period at a fixed time interval t0, and the laying hen motion data includes the position of the laying hen in the cage; the laying hen motion data is obtained and processed to obtain a motion trajectory distribution point map of the laying hen group in the cage; the motion center and the non-motion center are calculated according to the motion trajectory distribution point map, and the motion center and the non-motion center are set as the second illumination data collection point.

[0065] Furthermore, cluster analysis is performed on the points on the motion trajectory distribution point map to obtain a cluster center, which is the motion center;

[0066] Furthermore, the distance from the point on the motion trajectory distribution point map to the motion center is calculated, and the point farthest from the motion center is found. This point represents an extreme case of the edge or sparse part of the motion trajectory, that is, the non-motion center.

[0067] A motion monitoring device is installed on the foot of each laying hen in the cage. The movement center and non-motion center are calculated based on the movement trajectory distribution point diagram of the laying hen group, and set as the second lighting data collection point. The sensitivity of laying hens to light is utilized to design the collection point to ensure the accuracy and reliability of the data, providing data support for the subsequent analysis of the lighting uniformity inside the laying hen cage.

[0068] Furthermore, the light intensity data includes:

[0069] A first illumination data collection point position of the first collection point unit and a second illumination data collection point position of the second collection point unit are acquired, and illumination intensity is measured to obtain a first illumination intensity data set and a second illumination intensity data set.

[0074] Furthermore, as shown in Table 1, the first light intensity of the collection point in the farm at a certain moment is shown. The table shows the specific location of the collection point and the light intensity of the collection point. As shown in Table 2, the second light intensity of the collection point in some cages at a certain moment is shown.

[0075] This data collection method not only allows us to obtain light intensity data at key points within the farm, but also within the areas where the laying hens are active, providing detailed data support for subsequent lighting management optimization. This light intensity data set will become an important basis for evaluating lighting equipment performance, adjusting lighting plans, and optimizing cage environments.

[0076] The illumination uniformity judgment module obtains and processes the illumination intensity data to obtain illumination uniformity, and issues an early warning if the illumination uniformity does not fall within a preset uniformity range;

[0077] Furthermore, the illumination uniformity judgment module includes:

[0078] Acquire a first light intensity data set, merge and perform weighted processing to obtain a first uniformity; acquire a second light intensity data set, merge and perform processing to obtain a second uniformity;

[0079] The first uniformity and the second uniformity are obtained and processed to obtain the farm lighting uniformity. If the farm lighting uniformity does not fall within the preset uniformity range, an early warning of uneven farm lighting is issued. The calculation formula for the farm lighting uniformity is:

[0080]

[0081] Wherein, GZJYD represents the illumination uniformity of the farm, β1 represents the weight coefficient of the first uniformity, M represents the number of the first illumination data collection points, I m represents the illumination intensity of the mth first illumination data collection point, β2 represents the weight coefficient of the second uniformity, N represents the number of the motion centers, the number of non-motion centers is the same as the number of motion centers, I n ′ represents the illumination intensity of the nth motion center, I n ″ represents the light intensity of the nth non-moving center.

[0082] Furthermore, the lighting uniformity of the laying hen farm is 28.83, which is within the preset uniformity range of 26-30, and the lighting uniformity of the farm meets the standard.

[0083] Lighting is one of the important factors affecting the production performance of laying hens. Uneven lighting may cause various abnormal behaviors in laying hens, such as irritability and pecking, and may even affect the growth and egg-laying performance of laying hens. The lighting uniformity judgment module can accurately judge the lighting uniformity of the farm by acquiring and processing light intensity data, and issue an early warning when the lighting is uneven, thereby improving the efficiency and real-time monitoring of the farm's lighting.

[0084] The structure of the light source adjustment module is as follows Figure 3 The figure includes a sound index unit and a motion trajectory unit;

[0085] The sound index unit acquires and processes sound data of the laying hen to obtain a sound index, and performs a first local illumination adjustment if the sound index exceeds a preset sound threshold;

[0086] Furthermore, the workflow of the sound index unit is as follows: Figure 4 Shown, including:

[0087] The sound data unit includes a plurality of sound collection devices, and the positions of the sound collection devices are the same as the positions of the first light data collection points;

[0088] Acquiring and processing the sound data collected by the sound collection device to obtain a sound index, wherein the sound data includes sound pressure level, spectrum analysis, sound duration, sound waveform, and sound characteristic values, wherein the sound characteristic values ​​include average sound pressure, maximum sound pressure, and minimum sound pressure;

[0089] Furthermore, the sound data of laying hens in the non-eating period are collected at fixed intervals, the sound data collected the most recently G times are obtained and the sound index is calculated. The calculation formula of the sound index is:

[0090]

[0091] Among them, RE sound Represents the sound index, α1 represents the sound pressure level data collected for the gth time The weight coefficient, α2 represents the spectrum analysis data collected for the gth time The weight coefficient, α3 represents the sound duration data collected for the gth time The weight coefficient, α4 represents the sound waveform data collected for the gth time The weight coefficient, α5 represents the average sound pressure data collected for the gth time The weight coefficient, α6 represents the maximum sound pressure data collected for the gth time The weight coefficient, α7 represents the minimum sound pressure data collected for the gth time Table 3 shows the sound index obtained by processing the data from some sound collection devices.

[0094] Furthermore, if the sound index exceeds the preset sound threshold, the LED light source around the sound collection device is acquired and the power of the LED light source is adjusted. The first adjustment formula is:

[0095]

[0096] Among them, P new Indicates the LED light source power after adjustment according to the sound index, P current Indicates the current LED light source power, RE sound Represents the sound index, RE threshold Represents the preset sound threshold, RE max represents the maximum sound index, and k represents the power adjustment coefficient.

[0097] By acquiring and processing the sound data of laying hens through the sound index unit to obtain the sound index, and then adjusting the local lighting according to the sound index, it can not only improve the comfort of the laying hen breeding environment and optimize the breeding environment management, but also improve the breeding efficiency and output, and increase the egg production rate of laying hens.

[0098] The motion trajectory unit obtains and processes the illumination data collected at the second illumination data collection point to obtain an illumination intensity difference, and performs a second local illumination adjustment if the illumination intensity difference is greater than a preset threshold;

[0099] Furthermore, the motion trajectory unit includes:

[0100] The light intensity at the movement center and the non-movement center is obtained and processed to obtain a light intensity difference ΔI = |I′-I″|, where I′ represents the light intensity at the movement center and I″ represents the light intensity at the non-movement center. If the light intensity difference is greater than a preset threshold, the LED light source around the cage is obtained and the power of the LED light source is adjusted. The second adjustment formula is:

[0101]

[0102] Among them, P′ new Indicates the LED light source power after adjustment according to the light intensity difference, P current Indicates the current LED light source power, ΔI indicates the light intensity difference, I threshold Indicates the preset light intensity difference threshold, I max Indicates the maximum light intensity difference, and w indicates the adjustment coefficient.

[0103] By detecting the difference in light intensity between the movement center and the non-movement center, the system can promptly detect problems such as uneven lighting or insufficient light intensity, thereby improving detection accuracy. The second adjustment formula of power is used to realize automatic detection and adjustment of light intensity, reducing the frequency and difficulty of manual intervention, improving the level of automation in cage management, and increasing production efficiency.

[0104] Furthermore, when the area monitored by the sound index unit and the motion trajectory unit is the same area and local illumination adjustment is performed together, the adjusted power is the weighted sum of the above-mentioned adjusted powers, that is, P″ new =ρ1·P new +ρ2·P′ new , where P″ new represents the adjusted power after weighted calculation, and ρ1 is the LED light source power P after adjustment according to the sound index. new The weight coefficient, ρ2 is the LED light source power P′ adjusted according to the light intensity difference new The weight coefficient of .

[0105] The egg production capacity module obtains and processes egg data to obtain the production capacity error;

[0106] Furthermore, the egg production capacity module includes:

[0107] The egg data is obtained and processed to obtain the egg productivity index EPI, wherein the egg data includes the number of eggs and the weight of eggs; the calculation formula of the egg productivity index is:

[0108]

[0109] Among them, θ1 represents the weight coefficient of egg data, γ1 represents the weight coefficient of the number of eggs, Num represents the egg production on that day, Num expected represents the expected egg production, γ2 represents the weight coefficient of egg weight, L represents the number of randomly sampled eggs, egg l ′ represents the weight of the first egg on the day of random sampling, egg l ″ represents the weight of the lth egg randomly sampled yesterday, and θ2 represents the weight coefficient of yesterday’s egg productivity index EPI′.

[0110] The difference between the egg production index and the preset egg production index is calculated to obtain the production error ΔEPI of the laying hen during the peak egg-laying period.

[0111] The daily egg production capacity index is calculated by obtaining the number and weight of eggs and the egg production capacity index of the farm yesterday. By calculating the difference between the egg production capacity index and the preset egg production capacity index, the production capacity error of the laying hens during the peak laying period is obtained, which can accurately evaluate the production efficiency of the laying hens.

[0112] The production monitoring module calculates a production monitoring index and issues an early warning based on the production monitoring index.

[0113] Furthermore, the production monitoring module includes: obtaining the lighting uniformity of the farm, the sound index and the production capacity error and processing them to obtain a comprehensive monitoring index. If the comprehensive monitoring index falls within a preset monitoring range, the laying hen farm is in an optimal production state; the calculation formula of the comprehensive monitoring index is:

[0114]

[0115] Wherein, CMI represents the comprehensive monitoring index, ω1 represents the weight coefficient of the farm lighting uniformity, ω2 represents the weight coefficient of the sound index, and ω3 represents the weight coefficient of the production capacity error. Since the position of the sound collection device is the same as the position of the first light data collection point, the number of sound collection devices is M. Represents the mth sound index.

[0116] Furthermore, if the comprehensive monitoring index falls outside the preset monitoring range, a warning alert is issued indicating that the laying hen farm has a breeding problem not related to light source control. Calculations show that the comprehensive monitoring index on the 14th day of the laying period is 14.32, which falls within the preset monitoring range of 13-15, indicating that the laying hen farm is operating at optimal production efficiency.

[0117] A comprehensive monitoring index was designed by combining lighting data and egg production data to analyze the egg production efficiency of the farm under reasonable lighting conditions. If the comprehensive monitoring index exceeds the preset monitoring range, it will warn of potential non-light source control problems such as feed nutrition, temperature and humidity management, disease or chicken house layout, thereby reducing problem location time.

[0118] Furthermore, by obtaining historical data of the peak egg-laying period of laying hens in the historical database and performing data analysis and processing, the above-mentioned preset uniformity interval, preset sound threshold, maximum sound threshold, preset light intensity difference threshold, maximum light intensity difference, preset egg production capacity index and preset monitoring interval data can be obtained.

[0119] Scientific preset parameters are calculated using historical data from peak egg-laying periods to ensure that the parameter settings are reasonable and meet actual production needs, thereby improving the accuracy of farm management.

[0120] The lighting data acquisition module divides the collection points in detail and then collects the lighting data to ensure the accuracy and representativeness of the data; then the lighting uniformity judgment module can judge in real time whether the lighting intensity of the farm is uniform. Once unevenness is found, an early warning will be issued immediately to improve the monitoring efficiency of the lighting environment of the farm; the light source adjustment module adjusts the local power of the LED light source from two aspects, realizes the automatic detection and adjustment of the light intensity, and improves production efficiency; the production monitoring module comprehensively considers the lighting uniformity, sound index and production capacity error, and calculates the comprehensive monitoring index, which can fully reflect the production efficiency of the farm. Once it exceeds the range, the system will immediately issue an early warning to remind the farm that there are breeding problems that are not controlled by light sources. Through the above method, the present invention realizes real-time monitoring and local adjustment of the light intensity of the farm.
