Description

Technical Field

[0001] The invention relates to the technical field of poultry egg-laying monitoring, and in particular to a multifunctional poultry egg-laying monitoring device and a monitoring method. Background Art

[0002] Caged egg-laying poultry can effectively improve the accurate evaluation of individual egg-laying performance and accelerate the process of seed selection and breeding. Comprehensive monitoring of the egg-laying quantity and quality of caged egg-laying poultry can help managers gain a deep understanding of the production efficiency and health status of poultry, and optimize management measures based on these data, such as adjusting feed structure, improving breeding environment, and strengthening health management, aiming to enhance the egg-laying capacity of poultry and improve overall breeding benefits.

[0003] With the development of animal husbandry, the breeding industry is gradually moving towards a higher level of scale and mechanization, and production efficiency is constantly improving. The traditional way of manually recording egg-laying performance can no longer meet the current needs of large and medium-sized farms in processing a large amount of egg-laying information. On the other hand, the introduction of computer technology and automatic control technology has provided new opportunities for information recording and analysis in the poultry breeding industry, and promoted the integration and development of breeding information management systems.

[0004] In the prior art, patent CN 116530438 A discloses a device, method and system for inspecting and determining the egg-laying performance of individual laying ducks in cages, which is provided with multi-layer breeding cages and an inspection and detection device capable of translational movement. The inspection and detection device is provided with detection sensors and cameras for each layer, which can inspect and detect the parameters of duck eggs. In addition, the patent also provides a horizontally running conveyor belt to collect the eggs of each layer horizontally. The patent method has the following problems:

[0005] (1) It is necessary to set up cameras and detection sensors on each layer to detect fallen eggs on the spot, which is very costly;

[0006] (2) The inspection device moves to confirm whether eggs are laid, but the real-time performance is low and the egg laying time cannot be accurately obtained, which affects the accuracy of subsequent statistics;

[0007] (3) It is difficult to ensure the subsequent traceability of eggs by horizontal conveying and aggregation through belts, and it is easy to mess up the order of eggs, which is not conducive to subsequent detection. Summary of the invention

[0008] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a multifunctional poultry egg-laying monitoring device and monitoring method which has low monitoring cost, high factuality and can timely count the egg-laying time.

[0009] Technical solution: To achieve the above-mentioned purpose, the multifunctional poultry egg-laying monitoring device of the present invention comprises a feeding rack, on which feeding cages distributed in multiple layers are installed, and each layer has a plurality of the feeding cages;

[0010] It also includes a monitoring system for monitoring the egg-laying conditions of the poultry in each of the breeding cages, a conveying system for conveying the eggs, and a detection system for detecting the indicators of the eggs;

[0011] The detection system includes an egg storage mechanism installed at the location of each breeding cage, and also includes a camera;

[0012] The egg storage mechanism comprises a mechanism base, a slide and a rotating frame, wherein the slide is fixed and tilted relative to the mechanism base; the rotating frame is a U-shaped structure made of an elastic steel wire frame, both ends of which are rotatably installed relative to the mechanism base, and a torsion spring is arranged between the rotating frame and the mechanism base; a limiting mechanism acting on the rotating frame is fixed on the slide; when the limiting mechanism of the rotating frame contacts, the rotating frame and the slide are arranged in a V shape;

[0013] An identification plate is fixedly mounted on the rotating frame, and the identification plate can be switched between a hidden state and a visible state. In the visible state, the identification plate can be recognized by the camera;

[0014] A plurality of the egg storage mechanisms are arranged within the field of view of the camera.

[0015] Furthermore, the identification plate has a special color, and / or has special characters or a recognizable code, and / or is capable of self-luminescence.

[0016] Further, the conveying system comprises a movable seat body capable of moving between the breeding rack and the detection system, a vertical conveying device is installed on the movable seat body, and also comprises a release mechanism;

[0017] The vertical conveying device comprises a shell, a slide rail for guiding the shell is fixed on the feeding frame, and a driving mechanism for driving the shell to slide relative to the feeding frame is installed between the shell and the feeding frame; the lower end of the shell has an egg outlet;

[0018] A vertical conveyor belt is installed in the shell, and support plates are fixed equidistantly in the circumferential direction of the vertical conveyor belt. A plurality of egg storage grids are formed between the support plates, the vertical conveyor belt and the shell. As the vertical conveyor belt runs, the egg storage grids can move up and down to achieve the lifting and lowering of poultry eggs; the shell is provided with a plurality of egg entry buckets equidistantly arranged in the vertical direction; the release mechanism includes a pull rod located at each of the egg entry buckets, and the pull rod can act on the rotating frame to release the eggs blocked by the rotating frame into the egg entry buckets.

[0019] Furthermore, all the pull rods move in linkage under the action of a linkage mechanism; the linkage mechanism includes a linkage rod connecting the pull rods, and the linkage rod can perform lifting motion under the action of a linear motion driving element. In this way, the linear motion driving element can drive all the pull rods to move synchronously through the linkage rod, acting on the egg storage mechanisms located in the same row, thereby realizing the simultaneous release of poultry eggs by a row of egg storage mechanisms, and achieving high egg retrieval efficiency.

[0020] Furthermore, baffles are provided on both sides of the slide, and the baffles can prevent the baffles from falling from the sides of the slide.

[0021] The slide is formed by bending a cylindrical metal strip and has two symmetrically arranged guide rods. Each of the guide rods is a U-shaped structure with a turning portion at the lower end. The side rods of the rotating frame move within the U-shaped structure. The turning portion is a limiting mechanism for limiting the position of the rotating frame.

[0022] Specifically, the operation process of the above monitoring system is as follows: in the initial state, when there are no eggs in the egg storage mechanism, the rotating frame is in a horizontal state, and its free end is located at the high end of the slide. At this time, the identification plate is also in a horizontal state, and in the image captured by the camera, the identification plate is in a visually hidden state. When the poultry in the breeding cage lays eggs, the eggs roll out of the breeding cage into the egg storage mechanism and slide down the slide. During the sliding of the eggs, they apply torque to the rotating frame to rotate the rotating frame, and the free end of the rotating frame drops until the rotating frame contacts the limit mechanism. At this time, the identification plate is in an upright state, and in the image captured by the camera, the identification plate is in a clearly identifiable visible state. During the rotation of the rotating frame, the torsion force provided by the torsion spring can provide resistance to slow down the descent of the eggs.

[0023] When the conveying system takes eggs, the driving mechanism drives the vertical conveying device to move to a row of feeding cages, so that each egg-entry bucket is directly opposite to each egg storage mechanism, and the linear motion driving element drives the linkage rod to rise, so that the pull rod presses the free end of the rotating frame at the corresponding position upward, and the rotating frame is deformed and expanded outward under the action of the upward extrusion force, so that the poultry eggs can pass through the middle and fall into the egg-entry bucket. The poultry eggs enter the egg storage grid for storage through the egg-entry bucket. Due to the large size of the feeding rack, there are multiple egg storage grids between two adjacent egg-entry buckets. After completing the egg-taking operation of a row of egg storage mechanisms, the vertical conveyor belt runs a step distance, so that all the egg storage grids move a distance of the height of the egg storage grid. In this way, the vertical conveying device can move the position of the next row of feeding cages to realize the egg-taking operation of the next row of egg storage mechanisms. After the egg-taking is completed, the vertical conveying device moves to the release position and releases all the poultry eggs in it to the detection system.

[0024] The control system records the number of the breeding cage corresponding to the eggs in each egg storage grid in real time, so that a number sequence can be formed, so that each egg released to the detection system has an accurate source number, which is convenient for data management.

[0025] Further, the detection system includes a weighing unit, an appearance feature detection unit, an eggshell feature detection unit and an internal feature detection unit which are arranged in sequence from front to back;

[0026] The appearance feature detection unit visually detects the eggshell color and egg shape index of the poultry eggs;

[0027] The eggshell characteristic detection unit detects the eggshell strength and eggshell thickness of the poultry eggs;

[0028] The internal characteristic detection unit can crack the egg to obtain the egg white and the egg yolk, and detect the egg yolk ratio and the Haugh unit.

[0029] A multifunctional poultry egg-laying monitoring method, based on the above-mentioned poultry egg-laying monitoring device, comprises:

[0030] Acquire an image through the camera;

[0031] Extract features from the image to determine whether the state of the sign at each feature position in the image has changed, that is, whether it has changed from a hidden state to a visible state;

[0032] When the state of the identification plate changes, the number of the breeding cage is obtained according to the position of the identification plate whose state changes in the image, and the time when the image is obtained is recorded as the egg-laying time of the poultry in the breeding cage;

[0033] Based on the egg-laying time data of the poultry in each of the breeding cages over a period of time, various egg-laying index data of the poultry are obtained.

[0034] Furthermore, the egg-laying index data include the age of first laying, average egg-laying interval, production capacity, the number of eggs laid by the hens in the house, and the number of qualified breeding eggs laid by the hens in the house.

[0035] Among them, the age of first laying is calculated as the age when the daily egg production rate of laying hens or laying ducks reaches 50% for the first time, and the age when the daily egg production rate of broiler chickens or broiler ducks exceeds 5% for the first time; the average egg-laying interval is calculated by counting the individual egg-laying intervals of each poultry, and then calculating the average egg-laying interval of the group based on the individual egg-laying intervals; the production capacity is the number of eggs laid by poultry within a fixed time (such as a week), and the average number of eggs laid by the group within a fixed time.

[0036] Number of eggs laid by hens entering the house = total number of eggs laid at 72 weeks of age / number of hens entering the house; number of qualified breeding eggs laid by hens entering the house = total number of qualified eggs laid at 72 weeks of age / number of hens entering the house.

[0037] Furthermore, the method further comprises:

[0038] Obtaining egg weight data through a weighing unit;

[0039] Based on the weight data and the egg-laying time, indicators including the starting egg-laying weight, the egg weight at 43 weeks of age, and the total egg weight are obtained.

[0040] Among them, the first egg weight is the weight of non-double-yolk eggs laid on the first day of laying. If there are multiple eggs laid on that day, they will be weighed and counted one by one.

[0041] Total number of eggs laid = the sum of the egg weights laid each day during the laying period / the sum of the number of chickens raised each day during the laying period * the number of days in the laying period.

[0042] Egg weight at 43 weeks of age is recorded as follows:

[0043] Individual record: The average weight of three or more consecutive eggs of the individual at 43 weeks of age is taken as the egg weight of the individual. Group record: The weight of more than 100 eggs is randomly weighed at 43 weeks of age.

[0044] Furthermore, the method further comprises:

[0045] It is judged whether each row of egg storage mechanisms meets the egg taking condition, and if so, the conveying system is controlled to go to the row of egg storage mechanisms to take eggs.

[0046] Beneficial effects: The multifunctional poultry egg-laying monitoring device and monitoring method of the present invention have the following advantages:

[0047] Beneficial effects:

[0048] (1) An egg storage mechanism with an identification plate is used so that when an egg enters the egg storage mechanism, the identification plate can be revealed. Since the frame rate of the camera to capture images is very high, the egg-laying status of all poultry in the cages within the field of view can be obtained in real time through the identification plate, and the exact time of egg-laying of each poultry can be obtained, so that the egg-laying status of the poultry can be more accurately counted.

[0049] (2) A conveying system is provided for use with the egg storage mechanism, which can facilitate egg retrieval and delivery to the detection system and facilitate data management.

[0050] (3) By setting up the above-mentioned detection units, various index data of poultry eggs can be obtained at one time without the need for separate testing, which greatly improves the detection efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0059] The present invention will be further described below in conjunction with the accompanying drawings.

[0060] like Figure 1-2 The multifunctional poultry egg-laying monitoring device shown comprises a feeding rack 1, on which feeding cages 2 distributed in multiple layers are installed, and each layer has a plurality of the feeding cages 2; it also comprises a monitoring system for monitoring the egg-laying conditions of the poultry in each of the feeding cages 2, a conveying system for conveying the eggs, and a detection system for detecting the indicators of the eggs.

[0061] The detection system comprises an egg storage mechanism 3 installed at the location of each breeding cage 2, and also comprises a camera 4. A plurality of the egg storage mechanisms 3 are arranged within the field of view of the camera 4.

[0062] like Figure 3As shown, the egg storage mechanism 3 includes a mechanism base 31, a slide 32 and a rotating frame 33, wherein the slide 32 is fixed and tilted relative to the mechanism base 31; the rotating frame 33 is a U-shaped structure made of an elastic wire frame, both ends of which are rotatably installed relative to the mechanism base 31, and a torsion spring 34 is arranged between the rotating frame 33 and the mechanism base 31; a limiting mechanism 36 acting on the rotating frame 33 is fixed on the slide 32; when the limiting mechanism 36 of the rotating frame 33 contacts, the rotating frame 33 and the slide 32 are arranged in a V shape.

[0063] The slideway 32 has baffles 37 on both sides, which can prevent the baffles 37 from falling from the sides of the slideway 32. The slideway 32 is formed by bending a cylindrical metal strip, and has two symmetrically arranged guide rods, each of which is a U-shaped structure with a bend at the lower end, and the side rods of the rotating frame 33 move in the U-shaped structure, and the bend is a limit mechanism 36 for limiting the position of the rotating frame 33.

[0064] The rotating frame 33 is fixedly mounted with a sign 35, and the sign 35 can be hidden in a hidden state (such as Figure 3 ) and manifestation states (such as Figure 4 ), in the displayed state, the identification plate 35 can be recognized by the camera 4. The identification plate 35 has a special color, and / or has special characters (such as numbers) or recognizable codes (such as QR codes), and / or can emit light by itself.

[0065] The conveying system includes a movable base 5 that can move between the breeding rack 1 and the detection system. A vertical conveying device 6 is installed on the movable base 5, and also includes a releasing mechanism 7.

[0066] like Figure 6 As shown, the vertical conveying device 6 includes a shell 61, a slide rail 65 for guiding the shell 61 is fixed on the feeding rack 1, and a driving mechanism for driving the shell 61 to slide relative to the feeding rack 1 is also installed between the shell 61 and the feeding rack 1; the lower end of the shell 61 has an egg outlet 66.

[0067] A vertical conveyor belt 62 is installed in the shell 61, and a support plate 63 is fixed equidistantly on the circumference of the vertical conveyor belt 62. A plurality of egg storage grids are formed between the support plate 63, the vertical conveyor belt 62 and the shell 61. As the vertical conveyor belt 62 runs, the egg storage grids can move up and down to achieve the lifting and lowering of poultry eggs; the shell 61 has a plurality of egg hoppers 64 arranged equidistantly in the vertical direction; Figure 1 and Figure 5As shown, the release mechanism 7 includes a pull rod 71 located at each of the egg-entering buckets 64, and the pull rod 71 can act on the rotating frame 33 so that the eggs blocked by the rotating frame 33 are released into the egg-entering bucket 64. The rotating frame 33 is provided with a reinforcing portion 33a for the pull rod 71 to act on. The reinforcing portion 33a is π-shaped, and the two side rods of the rotating frame 33 are respectively provided with pre-bent portions 33b, and the pre-bent portions 33b are V-shaped. The upper end of the pull rod 71 has a U-shaped groove. The pull rod 71 rises and acts on the reinforcing portion 33a. The reinforcing portion 33a enters the U-shaped groove and is squeezed and raised by the pull rod 71, so that the rotating frame 33 can be deformed outward along the pre-bent portion 33b, so that the poultry eggs can pass between the two side rods.

[0068] All of the pull rods 71 ​​move in a linked manner under the action of the linkage mechanism 72; the linkage mechanism 72 includes a linkage rod 721 connecting each of the pull rods 71, and the linkage rod 721 can perform lifting and lowering movements under the action of the linear motion driving element 722. In this way, the linear motion driving element 722 can drive all of the pull rods 71 ​​to move synchronously through the linkage rod 721, acting on the egg storage mechanisms 3 located in the same row, thereby realizing the simultaneous release of poultry eggs by a row of egg storage mechanisms 3, and achieving high egg retrieval efficiency.

[0069] The operation process of the monitoring system is as follows: In the initial state, when there are no eggs in the egg storage mechanism 3, Figure 1 As shown, the rotating frame 33 is in a horizontal state, and its free end is located at the high end of the slide 32. At this time, the identification plate 35 is also in a horizontal state. In the image captured by the camera 4, the identification plate 35 is in a visually hidden state. When the poultry in the breeding cage 2 lays eggs, the eggs roll out of the breeding cage 2 into the egg storage mechanism 3 and slide down the slide 32. During the sliding process of the eggs, the rotating frame 33 applies a torque to the rotating frame 33 to rotate the rotating frame 33, and the free end of the rotating frame 33 drops until the rotating frame 33 contacts the limiting mechanism 36. Figure 2 As shown, the identification plate 35 is in an upright state at this time, and the identification plate 35 is in a clearly identifiable appearance state in the image captured by the camera 4. During the rotation of the rotating frame 33, the torsion force provided by the torsion spring 34 can provide resistance to slow down the descent of the eggs.

[0070] When the conveying system takes eggs, the driving mechanism drives the vertical conveying device 6 to move to a row of breeding cages 2, so that each egg-entry bucket 64 is directly opposite to each egg storage mechanism 3, and the linear motion driving element 722 drives the linkage rod 721 to rise, so that the pull rod 71 presses the free end of the rotating frame 33 at the corresponding position upward, and the rotating frame 33 is deformed and expanded outward under the action of the upward extrusion force, so that the poultry eggs can pass through the middle and fall into the egg-entry bucket 64, and the poultry eggs enter the egg storage grid through the egg-entry bucket 64 for storage. Due to the large size of the breeding frame 1, there are multiple egg storage grids between two adjacent egg-entry buckets 64. After completing the egg-taking operation of a row of egg storage mechanisms 3, the vertical conveyor belt 62 runs a step distance, so that all the egg storage grids move a distance of the height of the egg storage grid, so that the vertical conveying device 6 can move the position of the next row of breeding cages 2, and realize the egg-taking operation of the next row of egg storage mechanisms 3. After the egg-taking is completed, the vertical conveying device 6 moves to the release position and releases all the poultry eggs in it to the detection system.

[0071] The control system records the number of the breeding cage 2 corresponding to the poultry eggs in each egg storage grid in real time, so that a number sequence can be formed, so that each poultry egg released to the detection system has an accurate source number, which is convenient for data management.

[0072] In the above structure, an egg storage mechanism 3 with an identification plate 35 is used, so that when an egg enters the egg storage mechanism 3, the identification plate 35 can be revealed. Since the frame rate of the camera 4 to capture the image is very high, the egg-laying status of all the poultry in the breeding cages 2 within the field of view can be obtained in real time through the identification plate 35, and the accurate time of egg-laying of each poultry can be obtained, so that the egg-laying status of the poultry can be more accurately counted.

[0073] A conveying system is provided for use with the egg storage mechanism 3, which can facilitate taking out the eggs and conveying the eggs to the detection system, and is convenient for data management.

[0074] Preferably, the detection system comprises a weighing unit, an appearance feature detection unit, an eggshell feature detection unit and an internal feature detection unit which are arranged in sequence from front to back;

[0075] The appearance feature detection unit visually detects the eggshell color and egg shape index of the poultry eggs;

[0076] The eggshell characteristic detection unit detects the eggshell strength and eggshell thickness of the poultry eggs;

[0077] The internal characteristic detection unit can crack the egg to obtain the egg white and the egg yolk, and detect the egg yolk ratio and the Haugh unit.

[0078] By setting up the above-mentioned detection units, various index data of poultry eggs can be obtained at one time without the need for separate testing, which greatly improves the detection efficiency.

[0079] A multifunctional poultry egg-laying monitoring method, based on the above-mentioned poultry egg-laying monitoring device, such as Figure 7 As shown, the method includes the following steps S101-S104:

[0080] Step S101, acquiring an image through the camera 4;

[0081] Step S102, extracting features from the image to determine whether the state of the identification plate 35 at each feature position in the image has changed; that is, whether it has changed from a hidden state to a visible state;

[0082] Step S103, when the state of the identification plate 35 changes, the number of the breeding cage 2 is obtained according to the position of the identification plate 35 whose state changes in the image, and the time of obtaining the image is recorded as the egg-laying time of the poultry in the breeding cage 2;

[0083] Step S104, based on the egg-laying time data of the poultry in each of the breeding cages 2 within a period of time, obtaining various egg-laying index data of the poultry.

[0084] Preferably, the egg-laying index data described in the above step S104 include the age of first laying, the average egg-laying interval, the production capacity, the number of eggs laid by the hens in the house, and the number of qualified breeding eggs laid by the hens in the house.

[0085] Among them, the age of first laying is calculated as the age when the daily egg production rate of laying hens or laying ducks reaches 50% for the first time, and the age when the daily egg production rate of broiler chickens or broiler ducks exceeds 5% for the first time; the average egg-laying interval is calculated by counting the individual egg-laying intervals of each poultry, and then calculating the average egg-laying interval of the group based on the individual egg-laying intervals; the production capacity is the number of eggs laid by poultry within a fixed time (such as a week), and the average number of eggs laid by the group within a fixed time.

[0086] Number of eggs laid by hens entering the house = total number of eggs laid at 72 weeks of age / number of hens entering the house; number of qualified breeding eggs laid by hens entering the house = total number of qualified eggs laid at 72 weeks of age / number of hens entering the house.

[0087] Preferably, the method further comprises the following steps S201-S202:

[0088] Step S201, obtaining weight data of eggs through a weighing unit;

[0089] Step S202, based on the weight data and the egg-laying time, obtain indicators including the initial egg-laying weight, the egg weight at 43 weeks of age, and the total egg weight.

[0090] Among them, the first egg weight is the weight of non-double-yolk eggs laid on the first day of laying. If there are multiple eggs laid on that day, they will be weighed and counted one by one.

[0091] Total number of eggs laid = the sum of the egg weights laid each day during the laying period / the sum of the number of chickens raised each day during the laying period * the number of days in the laying period.

[0092] Egg weight at 43 weeks of age is recorded as follows:

[0093] Individual record: The average weight of three or more consecutive eggs of the individual at 43 weeks of age is taken as the egg weight of the individual. Group record: The weight of more than 100 eggs is randomly weighed at 43 weeks of age.

[0094] Preferably, the method further comprises:

[0095] It is judged whether each row of egg storage mechanisms meets the egg retrieval conditions. If yes, the conveying system is controlled to go to the row of egg storage mechanisms to retrieve eggs. The egg retrieval conditions are: whether there are enough eggs stored in the egg storage mechanisms, and / or whether the entry time of the poultry eggs in the egg storage mechanisms reaches the maximum egg storage time. If any of the conditions is met, the egg retrieval can be controlled. In this way, it can be prevented that the eggs in the egg storage mechanisms are not taken away yet and new eggs are put down, causing collision and damage of the eggs.

[0096] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
