Description

Technical Field

[0001] The present invention relates to the technical field of intelligent poultry farming, and in particular to an automatic weighing device and method for individual chickens on a disc-shaped platform. Background Art

[0002] In recent years, with the continuous increase in consumption, the poultry farming industry has gradually developed towards large-scale and intensive operations. This expansion in scale necessitates a shift from existing production and management methods to modern, automated, intelligent systems, making poultry farming more automated and efficient. A key component of the automated development of poultry farming is obtaining poultry weight data. Weight is the most intuitive indicator of a flock's growth and development, and a crucial metric for measuring flock development. Regular weighing is the only way to obtain flock weight data. Regular weighing provides insights into flock weight growth, which plays a key role in adjusting feed amounts, determining feed changes, and limiting feed intake. This ensures consistent flock uniformity, achieving optimal production performance, and improving the economic benefits of farming. Furthermore, regular weighing provides insights into flock health and facilitates the identification of birds with abnormal weights, allowing for timely remediation and minimizing losses.

[0003] Currently, large-scale farms still mostly rely on manual weighing. Sampling measurements are generally conducted every seven days, and the number of samples must not be less than 2%-5% of the total number of chickens in the flock. Manual weighing is not only time-consuming and labor-intensive, but also highly susceptible to scratches from the chickens during the catching process, posing a significant biosafety risk. Furthermore, weighing and catching chickens can easily cause stress in the flock, and if the catching process is too rough, it can cause secondary damage to the chickens, hindering their growth and development and seriously affecting their production performance. Manual weighing sampling involves manual weighing at random points, and because the chickens are stressed and move vigorously after being weighed, the weighing results are heavily dependent on the standardization of the operator's operation, making it difficult to guarantee the results.

[0004] Existing automated weighing equipment generally has a high base cost, making it difficult to implement and promote on large-scale farms. Most devices use cameras to capture images and employ image recognition to determine the number of birds weighed, thereby determining the average weight of the flock. However, the use of cameras undoubtedly increases the equipment cost. Furthermore, the cameras can be affected by factors such as installation location, lighting conditions, and dust, seriously interfering with normal operation and increasing errors in calculation results. Most devices rely on external power supplies, which further limits their installation locations and may require wiring adjustments within the chicken house, making their use very inconvenient. Furthermore, the data collected by the equipment is stored locally, requiring copying and manual calculation and analysis. This is a cumbersome process and can lead to data loss during power outages, making it both convenient and unsafe. Summary of the Invention

[0005] In view of the shortcomings of the above-mentioned manual weighing method and existing automatic weighing equipment, the purpose of the present invention is to provide an individual automatic weighing device and method for chickens with a disc-shaped platform, which uses a circular weighing plate as a weighing platform, allowing chickens to be weighed freely, realizing stress-free measurement of chickens, and realizing real-time data transmission through WiFi wireless transmission. At the same time, it can realize the judgment of individual chickens being weighed, and obtain the estimated value of individual chicken weight through numerical calculation, complete data storage and data display, thereby obtaining important indicators such as the average weight and uniformity of the chicken flock.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a method for automatically weighing individual chickens on a disc-shaped platform, which comprises: turning on the automatic individual chicken weighing equipment pre-installed on the chicken house shed, the equipment comprising a weighing module, a router and a host computer; the weighing module transmits the chicken weight data continuously detected during the breeding process to the host computer via the router, saves and processes the results determined to be individual chickens, and obtains valid individual chicken data; calculates the chicken group weight index based on the saved valid individual chicken data, and realizes continuous weight monitoring of the chicken group at various growth stages.

[0007] Furthermore, the weighing module transmits the weight data of the chickens continuously detected during the breeding process to the host computer via the router, including:

[0008] The weighing module sends the collected weight data to the host computer at preset time intervals;

[0009] The host computer saves the received weight data in order as a weight data list, and at the same time saves the time corresponding to the weight information as a time data list;

[0011] Determine whether the weight data at the current time node and the weight data at the previous time node meet the preset conditions. If the conditions are met, the weight data at the previous time node is recycled and saved in a new data list. The process continues until data that does not meet the conditions appears, at which point recycling stops.

[0012] Determine whether the number of data in the new data list is greater than the preset number. If the conditions are met, calculate the upper and lower quartiles and the upper and lower edges of the new data list to eliminate abnormal data, and calculate the average and standard deviation of the weight data as the estimated weight of the individual chickens. If the conditions are not met, no calculation is performed and the weight data is collected again;

[0013] The identified individual chicken weight data are saved in the database in sequence according to the timestamp.

[0014] Furthermore, the preset condition is that the weight data at the previous time node is within a range of ±30% of the weight data at the current time node.

[0015] Furthermore, the determination as a result of weighing a single chicken includes:

[0016] Use the last three digits of the chicken weight data list detected by the weighing module as a sliding window to perform sliding scanning;

[0017] The falling edge is determined based on the last three digits of the real-time sliding scan. If the top data of the falling edge is less than the preset value, it is determined that a single chicken has been weighed and left.

[0018] Furthermore, the determination of the falling edge includes:

[0019] If the last three digits W k 、W k-1 、W k-2 Satisfy W k-2 >W k-1 >W k If there is a relationship, the data will continue to decline;

[0020] Or, if the last three digits W k 、W k-1 、W k-2 Satisfy W k-1 >W k-2 >K·W k-1 >W k , the data has a short rise followed by a decline; where K is a pre-set coefficient;

[0021] If one of the above conditions is met, it is determined that there is a falling edge.

[0022] Furthermore, the calculation of the chicken group weight index includes:

[0023] The estimated weight values ​​of individual chickens obtained every day are further processed to determine whether the standard deviation corresponding to the data is less than the threshold, otherwise they should be eliminated;

[0024] The daily processing results were plotted and the average weight and weight uniformity of the flock were calculated.

[0042] To address the shortcomings of manual weighing methods and existing automatic weighing equipment, the present invention provides a disc-shaped platform for automatic weighing of individual chickens. The device and method include: activating an automatic weighing device for individual chickens pre-installed on a chicken house shed, the device comprising a weighing module, a router, and a host computer; the weighing module transmits the weight data of the chickens continuously detected during the breeding process to the host computer via the router, saves and processes the results determined to be individual chickens weighed, and obtains valid individual chicken data; and calculates the chicken group weight index based on the saved valid individual chicken data, thereby achieving continuous weight monitoring of the chicken group at various growth stages. The present invention can determine whether individual chickens have been weighed and obtain important indicators such as the average weight and uniformity of the chicken group.

[0043] In one embodiment of the present invention, a chicken individual automatic weighing device with a disc-shaped platform is provided. In this embodiment, Figure 1 As shown, the device includes a weighing module 1, a router 2, and a host computer 3. Each chicken stands on the weighing module 1, which sends its weight information to the router 2, which then transmits it to the host computer 3. The host computer 3 then stores and displays the received weight information.

[0044] like Figure 2 and Figure 3 As shown, the weighing module 1 includes an upper weighing plate 11, a lower weighing plate 12, a weighing sensor 13, a mounting bracket 14, a plastic foot 15, an AD conversion module 16, an MCU module 17, a lithium battery 18 and a fixing screw 19. The upper weighing plate 11 and the lower weighing plate 12 are fixedly connected to the mounting bracket 14 using fixing screws 19. The weighing sensor 13 is fixed between the two mounting brackets 14. The weighing sensor 13 is connected to the AD conversion module 16, and the AD conversion module 16 is connected to the MCU module 17. The collected chicken weight data is transmitted to the host computer 3 via the MCU module 17. The plastic foot 15 is fixed to the bottom of the lower weighing plate 12.

[0045] In the above embodiment, the upper and lower weighing pans 11 and 12 are preferably made of acrylic sheet materials and have screw holes reserved for secure connection with the mounting bracket 14 and plastic feet 15. The mounting bracket 14 can be made of aluminum, which is resistant to bending and lightweight. It is used to support the upper weighing pan 11 and concentrate the weight of the upper weighing pan 11 on the load cell 13.

[0046] In the above embodiment, wired connections are adopted between the weighing sensor 13 and the AD conversion module 16 , and between the AD conversion module 16 and the MCU module 17 . The lithium battery 18 is connected to the MCU module 17 to supply power to the entire weighing module 1 .

[0047] In the above embodiment, the height of the plastic feet 15 from the ground can be adjusted by nuts, so that the weighing module 1 can contact the floor of the chicken house or the cage net to ensure the stability of the weighing module 1.

[0048] In the above embodiment, the upper and lower weighing plates 11, 12 are circular discs with a diameter of 10-30 cm and a thickness of 6-8 mm, ensuring that the chickens can stand completely on the weighing module 1 without significant deformation. The height of the weighing module 1 is 5-8 cm, and in this embodiment, a height of 7 cm is preferred to ensure that chickens at all stages of breeding can be easily weighed. The maximum range of the weighing sensor 13 is 3-10 kg, which can easily adapt to various breeding stages and ensure reliable and accurate measurement data at each stage.

[0049] When in use, the device is fixed to the floor of the chicken house or the cage net. The weighing module collects data every 0.5 seconds and transmits it wirelessly to the host computer. When a bird stands on the collection module, its weight changes. Based on the bird's behavior, it is determined whether it is a single bird. The collected weight data is then recycled and calculated to obtain an estimated weight value for the bird. The individual weight data collected daily is analyzed and summarized, and displayed by the host computer software, enabling real-time weighing and monitoring of the flock.

[0050] In one embodiment of the present invention, a method for automatically weighing individual chickens on a disc-shaped platform is provided. The method is implemented based on the automatic weighing equipment for individual chickens in the above embodiments. In this embodiment, Figure 4 As shown, the method includes the following steps:

[0051] 1) Turn on the automatic weighing device for individual chickens pre-installed on the chicken house shed, which includes a weighing module, a router and a host computer;

[0052] 2) The weighing module transmits the weight data of the chickens continuously detected during the breeding process to the host computer via the router, saves and processes the results determined to be individual chickens, and obtains the valid data of the individual chickens;

[0053] 3) Calculate the flock weight index based on the saved effective data of individual chickens to achieve continuous weight monitoring of the flock at all growth stages.

[0054] In this embodiment, the following configuration is used as an example to describe the automatic weighing equipment for individual chickens. The weighing module 1, router 2, and host computer 3 are wirelessly connected. The upper and lower weighing plates 11 and 12 in the weighing module are made of circular acrylic plates with a diameter of 25 cm and a thickness of 8 mm. The plastic feet 15 have a bottom diameter of 3 cm. The mounting bracket 14 is made of aluminum alloy. The load cell 13 is a 10 kg resistance strain gauge pressure sensor. The AD conversion module 16 is an HX711 module with a gain factor of 128. The MCU module 17 is a WeMos D1 development board with a built-in WiFi antenna. The lithium battery 18 is a high-capacity 12000 mAh lithium battery. The weighing module 1 is set to a height of 5 cm. The router 2 transmits at a frequency of 2.4 GHz. The host computer 3 is equipped with control software to process, store, and send instructions for weight data.

[0055] When in use, the chicken individual automatic weighing device needs to be fixed on the chicken house shed, ensuring that the device is installed within the normal working range of the router 2 and keeping the device turned on until the end of the breeding. During the breeding process, the lithium battery 18 is replaced every two weeks. Figure 5 As shown, after the device boots up, host computer 3 connects to router 2 and waits for a connection from weighing module 1. Upon receiving data from weighing module 1, it determines whether a single chicken is being weighed based on the data changes. If so, the time and weight data are saved to a database table. If not, the system waits for data to be received again. Host computer 3 can also send instructions to weighing module 1 to pause data transmission and reset the weighing module 1 to zero.

[0056] In the above step 1), if Figure 5 As shown, the weighing module 1 requires network configuration when it is first started. The network address of the router and the IP address of the host computer 3 are entered on the web page. The weighing module 1 can then connect to the router 2 and send data to the designated host computer 3 via the IP address. After the wireless connection is established, the weighing module 1 tares and resets the value to zero. It then begins to read the analog signal changes from the load cell 13. The HX711 module converts the analog signal into a digital signal, which is then passed to the WeMos D1 development board. The WeMos D1 development board then wirelessly transmits the digital signal to the host computer 3 and receives instructions from the host computer 3 to determine whether to pause data transmission or tare and reset the value to zero.

[0057] In step 2), the data collected by weighing module 1 is sent via router 2 to host computer 3, which calculates and stores the data. The data collected by weighing module 1 is redundant. By analyzing the changes in the collected data, the data is cleaned, deleting redundant data and saving only valid data.

[0058] In this embodiment, the weighing module transmits the weight data of the chickens continuously detected during the breeding process to the host computer via the router, which specifically includes the following steps:

[0059] 2.1.1) The weighing module 1 sends the collected weight data to the host computer 3 at preset time intervals;

[0060] Preferably, the time interval is 0.5s

[0061] 2.1.2) The host computer 3 saves the collected weight information in order as a weight data list W i , and at the same time save the time corresponding to the weight information as the time data list T i ;

[0062] 2.1.3) Single chicken weighing judgment. Use the jump in weight information to identify the time node T when a single chicken is weighed. k , get the weight data list W according to the time node i Weight data W in k ;

[0063] 2.1.4) Determine the weight data W at the current time node k Compared with the weight data W at the previous time node k-1 Whether the preset conditions are met, if the conditions are met, the weight data W of the previous time node is k-1 Recycle and save to the new data list W i ', judge W in turn k-2 、W k-3 ..., until data that does not meet the conditions appears, then the recycling stops;

[0064] The default condition is: 0.7W k <W k-1 <1.3W k , that is, whether the previous data size is within the ±30% range of the current data.

[0065] 2.1.5) Determine the new data list W i 'Whether the number of data in is greater than the preset number, the preferred preset number in this embodiment is 5, if the condition is met, a new data list W is calculated i The upper and lower quartiles and the upper and lower edges of the data are used to eliminate abnormal data and calculate the mean and standard deviation of the weight data as the estimated weight of the individual chickens. If the conditions are not met, no calculation is performed and the weight data is collected again.

[0066] 2.1.6) The weight data of the identified chickens are saved in the database in sequence according to the timestamp.

[0067] In step 2) above, the data sent by weighing module 1 to host computer 3 changes to determine whether weighing module 1 has recorded a single chicken on the scale. The estimated weight of the individual chicken is calculated based on the recorded weight data and the result is stored in host computer 3. Because weight data is transient, when a single chicken leaves weighing module 1, there is a significant falling edge in the data. This falling edge is then identified to determine whether a single chicken has been weighed.

[0068] Determining the result of weighing a single chicken includes the following steps:

[0069] 2.2.1) List of chicken weight data detected by weighing module W i The last three digits of W k 、W k-1 、W k-2 As a sliding window, perform sliding scanning;

[0070] 2.2.2) According to the last three digits of the real-time sliding scan, W k 、W k-1 、W k-2 Determine the falling edge. If the falling edge top data W k If the value is less than the preset value, it is determined that a single chicken has been weighed and left.

[0071] Among them, the method for determining the falling edge is:

[0072] If the last three digits W k 、W k-1 、W k-2 Satisfy W k-2 >W k-1 >W k If there is a relationship, the data will continue to decline;

[0073] Or, if the last three digits W k 、W k-1 、W k-2 Satisfy W k-1 >W k-2 >K·W k-1 >W k relationship, the data has a short rise followed by a drop; wherein K is a pre-set coefficient; in this embodiment, the preferred value of coefficient K is 0.95;

[0074] If one of the above conditions is met, it is determined that there is a falling edge.

[0075] In the above step 2.2.2), the preset value is preferably 10g. k If the weight is less than 10g, it is considered a single chicken and the chicken is weighed and removed.

[0076] In step 3) above, the saved valid data of individual chickens are processed to calculate the chicken group weight index:

[0077] The daily estimated weights of individual birds are further processed to determine if the standard deviation of the data is less than a threshold (100g in this example). Otherwise, the birds are discarded. The daily results are graphed, and the average weight and weight uniformity of the flock are calculated, allowing for continuous weight monitoring at all stages of the flock's growth.

[0078] It can be seen that the present invention can realize the weighing of individual chickens in the whole breeding stage, without stress to the chickens, and reduces labor input costs. It is easy to arrange and does not require additional wiring. The data can be transmitted and displayed in real time, and the daily weight data of the chickens, weekly weight growth curve and weight changes in each stage are obtained through analysis, and timely warnings are given for abnormal weight conditions, thereby realizing weight monitoring of the chickens throughout the whole breeding cycle and guidance of chicken management decisions.

If the conditions are met, the weight data at the previous time node is recycled and saved in a new data list. The process continues until data that does not meet the conditions appears, at which point recycling stops. Determine whether the number of data in the new data list is greater than the preset number. If the conditions are met, calculate the upper and lower quartiles and the upper and lower edges of the new data list to eliminate abnormal data, and calculate the average and standard deviation of the weight data as the estimated weight of the individual chickens. If the conditions are not met, no calculation is performed and the weight data is collected again; The identified individual chicken weight data is saved in the database in sequence according to the timestamp; The determination is made as a result of weighing a single chicken, including: Use the last three digits of the chicken weight data list detected by the weighing module as a sliding window to perform sliding scanning; The falling edge is determined based on the last three digits of the real-time sliding scan. If the top data of the falling edge is less than the preset value, it is determined that a single chicken has been weighed and left.
