Description

Technical Field

[0001] The present invention relates to the technical field of breeding, and particularly relates to a chicken coop and a method for monitoring chicken group cough. Background Art

[0002] With the development of modern breeding models, especially the wide popularization of intensive breeding and three-dimensional breeding models, the health risks faced by poultry in the breeding process are increasing day by day. Among them, respiratory diseases have become one of the main problems affecting the health and production efficiency of poultry. The intensive breeding environment usually has a relatively high environmental humidity, poor air circulation, and a relatively dense layout of chicken groups. These factors not only increase the risk of disease transmission, but also cause huge economic losses once the disease breaks out.

[0003] In poultry respiratory diseases, cough is one of the more typical and obvious early symptoms. The appearance of cough in a chicken group usually means the existence of respiratory tract infection or irritative lesions, and other clinical symptoms such as increased body temperature and loss of appetite often accompany the cough phenomenon. Therefore, the abnormal increase of cough and body temperature can be used as an early signal to judge whether poultry is infected with respiratory diseases, and timely monitoring and diagnosis are crucial for disease prevention and control.

[0004] Currently, the traditional monitoring methods for chicken group respiratory diseases mostly rely on manual inspections. The performance data of the chicken group are collected by methods such as listening with the ear and visual inspection, and it is judged whether the chicken group has respiratory diseases based on the experience of relevant technical personnel. However, due to the large number of chickens in the chicken coop and the wide range of activities, manual inspections are time-consuming and laborious, and the method of judging whether the chicken group has respiratory diseases based on the experience of relevant technical personnel has a large error. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a chicken coop and a method for monitoring chicken group cough, so as to solve the problems that in the prior art, the method of relying on relevant technical personnel for manual inspections to monitor the health status of chickens has a high working intensity for technical personnel.

[0006] The problem that the method of judging whether the chicken group has respiratory diseases based on experience has a large error.

[0007] The present invention is realized through the following technical solutions:

[0008] A chicken coop, including a coop body with a hollow structure. A cage body for chickens to live in is arranged inside the coop body, and there is a gap between the outer side wall of the cage body and the inner side wall of the coop body. An installation block is arranged in the gap between the coop body and the cage body, and the installation block is slidably connected to the inner side wall of the coop body along the length direction of the coop body;

[0009] On the side of the mounting block facing the cage body, an acoustic sensor and a temperature sensor are fixedly installed. The acoustic sensor is used to collect the crowing information of the chickens in the cage body, and the temperature sensor is used to collect the body temperature information of the chickens in the cage body;

[0010] On the outer side wall of the shed body, a processing module and a warning module are fixedly installed. The processing module is used to process the information collected by the acoustic sensor and the temperature sensor and send instructions to the warning module, and the warning module is used to send warning information according to the instructions.

[0011] Furthermore, ventilation holes communicating the inside and outside of the shed body are provided on the side wall of the shed body, and impellers are rotatably fitted in the ventilation holes;

[0012] A linkage component is arranged between the impeller and the mounting block. When the mounting block slides in the shed body, the impeller is driven to rotate through the linkage component.

[0013] Furthermore, a plurality of ventilation holes are provided. The plurality of ventilation holes are evenly arranged along the sliding direction of the mounting block, and impellers are arranged in all the plurality of ventilation holes.

[0014] Furthermore, the linkage component includes a gear coaxially and fixedly connected to one end of the impeller facing the cage body and a rack meshing with the gear. The bottom surface of the rack is fixedly connected to the top surface of the mounting block.

[0015] Furthermore, the rack includes a connecting strip fixedly connected to the top surface of the mounting block and a plurality of sliding strips evenly arranged in the sliding direction of the mounting strip. One end of the connecting strip facing the sliding direction of the mounting block is open and has a hollow structure;

[0016] The sliding strips are perpendicular to the connecting strip. One end of the sliding strip penetrates through the top wall of the connecting strip and inserts into the connecting strip, and the sliding strip is slidably matched with the connecting strip;

[0017] A push strip is arranged at the open end of the connecting strip. The push strip is wedge-shaped facing one end of the opening of the connecting strip, and the inclined surface faces the top wall of the connecting strip. The wedge-shaped end of the push strip is inserted into the opening of the connecting strip and is slidably matched with the connecting strip. When the bottom end of the sliding strip abuts against the top surface of the push strip, the top end of the sliding strip protrudes out of the top surface of the connecting strip and inserts into the tooth slot of the gear.

[0018] Furthermore, a first lead screw is connected in series in the push strip and is in threaded fit. One end of the first lead screw facing away from the opening of the connecting strip penetrates through the end wall of the connecting strip and extends out of the connecting strip, and the first lead screw is rotatably matched with the connecting strip;

[0019] A first motor is fixedly connected to the outside of the connecting strip facing away from the opening end. The output end of the first motor is coaxially and fixedly connected to the first lead screw, and the first motor is electrically connected to the processing module.

[0020] A method for monitoring chicken cough, including using the above chicken shed, the monitoring method is as follows:

[0021] S1. Respectively collect the call information of chickens in the cage body through an acoustic sensor and the body temperature information of chickens in the cage body through a temperature sensor, and transmit the collected information to the processing module (Variational Autoencoder (VAE) model) to train the Variational Autoencoder (VAE) model;

[0022] S2. Through VAE, learn the latent distribution of the input data, generate a feature representation similar to the input data, use the call information training process as a sample to input into the first feature monitoring network, when the model error is stable, define the error loss1 of this model as threshold 1, use the body temperature information training process as a sample to input into the second feature monitoring network, and define the error loss2 as threshold 2 when the error is stable;

[0023] S3. According to the error between the input sample and the model parameters, the model will output a comparison result with threshold 1 or threshold 2, so as to judge whether the sample is abnormal and send a corresponding instruction to the warning module;

[0024] S4. The warning module issues corresponding warning information according to the received instruction.

[0025] Furthermore, the acoustic sensor is used to monitor the cough sound of chickens in real time, collect the call information of chicken cough, and save it to the specified path of the terminal;

[0026] Using existing functions, extract Mel Frequency Cepstral Coefficient (MFCC) features from the collected call information, generate a feature map of the audio, convert the feature map into a picture format, and save it in the specified path as the sample data of the first feature monitoring network.

[0027] Furthermore, the temperature sensor is used to monitor the body temperature of chickens in real time, collect the infrared thermal imaging map of abnormal body temperature of chickens, and save it to the specified path of the terminal as the sample data of the second feature monitoring network.

[0028] Furthermore, when the error between the input call information and the first feature monitoring network is lower than threshold 1, it indicates that the cough behavior of this chicken is normal, and when the error is greater than the threshold, it indicates that this chicken has a health problem;

[0029] When the error between the input body temperature information and the second feature monitoring network is lower than threshold 2, it indicates that the body temperature of this chicken is normal, and when the error is greater than the threshold, it indicates that this chicken has abnormal body temperature and has a health problem.

[0030] The beneficial effects of the present invention are as follows:

[0031] This chicken coop is designed such that mounting blocks are installed in the gaps between the cage body and the coop body, and the mounting blocks are slidably connected to the coop body along the length direction of the coop body. This enables the mounting blocks to drive the acoustic sensors and temperature sensors to move inside the coop body, facilitating the collection of the crowing information and body temperature information of chickens at different positions along the length direction of the coop body, replacing manual inspections and reducing the workload of relevant technicians. The collected information is then transmitted to a processing module outside the coop body. After processing the collected information, the processing module sends instructions to a warning module, and upon receiving the instructions, the warning module emits corresponding warning information outside the coop body, allowing relevant technicians to obtain the health status of the chickens outside the coop body.

[0032] A method for monitoring chicken coughs assesses the health status of chickens from two perspectives, namely crowing information and body temperature information, through multi-modal joint monitoring, improving the accuracy of monitoring. Crowing information can reflect the behavior patterns and health status of chickens, while body temperature information provides early warnings of abnormal body temperatures. By combining the two types of information, abnormal situations can be identified more comprehensively and accurately.

[0033] Other advantages, objectives, and features of the present invention will, to some extent, be elaborated in the subsequent description, and to some extent, will be obvious to those skilled in the art based on an examination of the following text, or can be learned from the practice of the present invention. The objectives and other advantages of the present invention can be achieved and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, terms such as "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0047] In addition, terms such as "the same" do not mean that the components are absolutely the same, but there may be slight differences. The term "vertical" only means that the positional relationship between components is more vertical relative to "parallel", and does not mean that the structure must be completely vertical, but may be slightly inclined.

[0048] Please refer to Figure 1-8, the present invention provides a technical solution: a chicken coop, including a coop body 1 with a hollow structure. Inside the coop body 1, there is a cage body 2 for chickens to live. There is a gap between the outer side wall of the cage body 2 and the inner side wall of the coop body 1. An installation block 3 is arranged in the gap between the coop body 1 and the cage body 2. The installation block 3 is slidably connected to the inner side wall of the coop body 1 along the length direction of the coop body 1;

[0049] On one side of the installation block 3 facing the cage body 2, an acoustic sensor 4 and a temperature sensor 5 are fixedly installed. The acoustic sensor 4 is used to collect the calling information of the chickens in the cage body 2, and the temperature sensor 5 is used to collect the body temperature information of the chickens in the cage body 2;

[0050] On the outer side wall of the coop body 1, a processing module 6 and a warning module 7 are fixedly installed. The processing module 6 is used to process the information collected by the acoustic sensor 4 and the temperature sensor 5, and send an instruction to the warning module 7. The warning module 7 is used to send a warning message according to the instruction.

[0051] In this solution: by arranging the installation block 3 in the gap between the cage body 2 and the coop body 1, and slidingly connecting the installation block 3 with the coop body 1 along the length direction of the coop body 1, the installation block 3 can drive the acoustic sensor 4 and the temperature sensor 5 to move inside the coop body 1, so as to facilitate collecting the calling information and body temperature information of the corresponding chickens at different positions in the length direction of the coop body 1, replacing manual inspections and reducing the work intensity of relevant technical personnel; and transmitting the collected information to the processing module 6 outside the coop body 1. After processing the collected information by the processing module 6, an instruction is sent to the warning module 7. After receiving the instruction, the warning module 7 sends a corresponding warning message outside the coop body 1, enabling relevant technical personnel to obtain the health status of the chickens outside the coop body 1.

[0052] On one side wall inside the coop body 1, a chute 15 extending along the length direction of the coop body 1 is provided. One side of the installation block 3 is embedded in the chute 15 and is slidably matched with the chute 15; outside the chute 15, a second lead screw 16 parallel to the chute 15 is provided. The installation block 3 is sleeved outside the middle of the second lead screw 16 and is connected by screw thread; both ends of the second lead screw 16 respectively penetrate through the two side walls of the coop body 1 along the length direction and extend outside the coop body 1, and the second lead screw 16 is rotationally matched with the coop body 1; one end of the second lead screw 16 is provided with a second motor 17. The second motor 17 is fixedly installed on the outer side wall of the coop body 1, and the output end of the second motor 17 is coaxially and fixedly connected with one end of the second lead screw 16. Among them, the temperature sensor 5 is an infrared temperature sensor 5, and the warning module 7 is a display screen. After receiving the instruction sent by the processing module 6, a corresponding warning pattern is presented on the display screen, transmitting information to relevant technical personnel visually. The acoustic sensor 4, the temperature sensor 5, and the warning module 7 are all electrically connected to the processing module 6.

[0053] During use, when it is necessary to monitor the health of the chickens in the cage body 2, the second motor 17 is started. The second motor 17 drives the second lead screw 16 to rotate forward together. The external thread on the second lead screw 16 applies a thrust along the axial direction of the second lead screw 16 to the mounting block 3, causing the mounting block 3 to slide forward in the chute 15. At the same time, the acoustic sensor 4 and the temperature sensor 5 are started to collect the call information and body temperature information of the chickens in the cage. After being processed by the processing module 6, corresponding warning information is issued on the warning module 7, so that relevant technical personnel can understand the health status of the chickens in the cage body 2. Moreover, the acoustic sensor 4 and the temperature sensor 5 move together with the mounting block 3 to collect the information of the chickens at various positions along the length direction of the shed body 1 in the cage body 2, replacing manual inspection.

[0054] When the mounting block 3 abuts against one side wall in the length direction of the shed body 1, the second motor 17 rotates reversely, causing the mounting block 3 to slide in the reverse direction in the chute 15. When the mounting block 3 abuts against the other side wall in the length direction of the shed body 1, the second motor 17 rotates forward again, causing the mounting block 3 to perform a reciprocating linear motion in the chute 15, enabling the acoustic sensor 4 and the body temperature sensor to cyclically collect the acoustic information and body temperature information of the chickens at various positions in the cage body 2, continuously monitoring the health status of the chickens in the cage body 2.

[0055] In this embodiment: Ventilation holes 11 communicating the inside and outside of the shed body 1 are provided on the side wall of the shed body 1, and impellers 12 are rotatably fitted in the ventilation holes 11;

[0056] A linkage assembly is provided between the impeller 12 and the mounting block 3. When the mounting block 3 slides in the shed body 1, the impeller 12 is driven to rotate through the linkage assembly.

[0057] In this solution: The ventilation holes 11 are used to communicate the air inside and outside the shed body 1. The impellers 12 are arranged in the ventilation holes 11. By rotating the impellers 12 forward or backward, airflows are generated to the outside or inside of the shed body 1, promoting the air circulation between the inside and outside of the shed body 1, exhausting the humid and hot air inside the shed body 1 or inputting fresh air into the shed body 1, providing a suitable living environment for the chickens, and reducing the probability of the chickens getting sick.

[0058] During use, when the mounting block 3 slides forward in the chute 15, the impeller 12 is driven to rotate forward through the linkage assembly, exhausting the humid and hot air inside the shed body 1; when the mounting block 3 slides in the reverse direction in the chute 15, the impeller 12 is driven to rotate in the reverse direction through the linkage assembly, inputting fresh air into the shed body 1.

[0059] In this embodiment: A plurality of the ventilation holes 11 are provided, and the plurality of ventilation holes 11 are uniformly arranged along the sliding direction of the mounting block 3, and impellers 12 are arranged in all the plurality of ventilation holes 11.

[0060] In this solution, when the mounting block 3 slides in the slide groove 15, it is linked to the impeller 12 at the corresponding position through a linkage assembly, so that the impeller 12 rotates forward or reversely, so that the corresponding vent 11 discharges hot and humid air or flows in fresh air, and the other vents 11 flow in fresh air or discharge hot and humid air, thereby promoting the mutual circulation of air between the inside and outside of the shed body 1.

[0061] In this embodiment, the linkage assembly includes a gear 13 coaxially fixedly connected to the end of the impeller 12 facing the cage body 2 and a rack 14 meshing with the gear 13 , and the bottom surface of the rack 14 is fixedly connected to the top surface of the mounting block 3 .

[0062] In this solution: a gear 13 is provided at one end of the plurality of impellers 12 facing the cage 2, and the length of the rack 14 can be less than or greater than the wheelbase of the two impellers 12. When the length of the rack 14 is less than the wheelbase of the two impellers 12, the rack 14 can mesh with the gear 13 of at most one of the impellers 12 at the same time, that is, it can drive at most one impeller 12 to rotate, and as the mounting block 3 slides continuously, the rack 14 can alternately mesh with the gears 13 of the plurality of impellers 12, thereby driving the plurality of impellers 12 to rotate in sequence;

[0063] When the length of the rack 14 is greater than the wheelbase of the two impellers 12 , the rack 14 can mesh with two adjacent gears 13 , three gears 13 , or multiple gears 13 at the same time to drive the meshing gears 13 to rotate, so that the corresponding impellers 12 rotate synchronously and exhaust or inject air from the multiple air vents 11 .

[0064] In this embodiment: the rack 14 includes a connecting strip 141 fixedly connected to the top surface of the mounting block 3 and a plurality of sliding strips 142 evenly arranged in the sliding direction of the mounting strip, and the connecting strip 141 has an opening at one end facing the sliding direction of the mounting block 3 and is a hollow structure;

[0065] The slide bar 142 is perpendicular to the connecting bar 141, one end of the slide bar 142 penetrates through the top wall of the connecting bar 141 and is inserted into the connecting bar 141, and the slide bar 142 and the connecting bar 141 are slidably matched;

[0066] A push bar 143 is provided at the open end of the connecting bar 141, and the push bar 143 is wedge-shaped at one end facing the opening of the connecting bar 141, and the inclined surface is toward the top wall of the connecting bar 141. The wedge-shaped end of the push bar 143 is inserted into the opening of the connecting bar 141 and slides with the connecting bar 141, and when the bottom end of the slide bar 142 abuts against the top surface of the push bar 143, the top end of the slide bar 142 protrudes outside the top surface of the connecting bar 141 and is inserted into the tooth groove of the gear 13.

[0067] In this solution: The rack 14 is formed by splicing a connecting bar 141 and a plurality of sliding bars 142. The sliding bars 142 serve as the teeth of the rack 14, and the sliding bars 142 are slidably connected to the connecting bar 141, enabling the sliding bars 142 to be slidably inserted into the interior of the connecting bar 141. When the bottom end of the sliding bar 142 abuts against the inner bottom surface of the connecting bar 141, the sliding bar 142 is completely inserted into the connecting bar 141, disengaging from the engagement with the gear 13, so as to reduce the number of teeth of the rack 14.

[0068] When it is necessary to increase the number of teeth of the rack 14, a push bar 143 is thrust into the connecting bar 141. The inclined surface of the wedge-shaped end of the push bar 143 pushes up the sliding bar 142, causing the top end of the sliding bar 142 to protrude out of the top surface of the connecting bar 141 until the bottom end of the sliding bar 142 abuts against the top surface of the push bar 143.

[0069] That is, the number of gears 13 meshing with the rack 14 can be controlled by controlling the number of teeth of the rack 14, so as to control the area covered by the corresponding impeller 12, and to control the efficiency of air flowing out of or into the shed body 1 near the mounting block 3. At the same time, during the process of the gear 13 starting to mesh with the rack 14 until disengaging from the contact with the rack 14, the moving speed of the mounting block 3 is fixed, so that the rotating speeds of the gear 13 and the impeller 12 are fixed, that is, the air flow rate passing through the through hole per unit time is fixed. By increasing or decreasing the number of teeth of the rack 14, the meshing transmission time can be increased or shortened, so as to increase or decrease the air flow rate in the through hole.

[0070] In this embodiment: A first lead screw 144 is connected in series inside the push bar 143 and is connected by screw thread. The end of the first lead screw 144 facing away from the opening of the connecting bar 141 penetrates through the end wall of the connecting bar 141 and extends outside the connecting bar 141, and the first lead screw 144 is rotationally matched with the connecting bar 141.

[0071] A first motor 145 is fixedly connected to the outside of the end of the connecting bar 141 facing away from the opening. The output end of the first motor 145 is coaxially and fixedly connected to the first lead screw 144, and the first motor 145 is electrically connected to the processing module 6.

[0072] In this solution: During use, the mounting block 3 slides within the sliding groove 15. The acoustic sensor 4 and the temperature sensor 5 collect the call information and body temperature information of the chickens at the corresponding positions. The processing module 6 analyzes and determines the health status of the chickens in this area. When the processing module 6 determines that there are health problems with the chickens in this area, the processing module 6 controls the first motor 145 to start. The first motor 145 drives the first lead screw 144 to rotate forward. The external thread on the first lead screw 144 exerts a thrust along the axial direction of the first lead screw 144 on the push bar 143, causing the push bar 143 to slide into the connecting bar 141 until the push bar 143 abuts against the end wall of the connecting bar 141 at the end facing away from the opening. The processing module 6 controls the first motor 145 to turn off; the push bar 143 pushes and lifts the slide bar 142 embedded in the connecting bar 141, increasing the number of teeth of the rack 14, promoting the air circulation between the air near the mounting block 3 and the outside air of the shed body 1, promoting the discharge of the air near the chickens with health problems, and reducing the probability of the surrounding healthy chickens being infected.

[0073] The mounting block 3 continues to slide within the sliding groove 15. When the processing module 6 determines that the chickens in the corresponding area are healthy, the processing module 6 controls the first motor 145 to start. The first motor 145 drives the first lead screw 144 to rotate reversely. The external thread on the first lead screw 144 exerts a thrust along the axial direction of the first lead screw 144 on the push bar 143, causing the push bar 143 to slide out of the connecting bar 141, causing the slide bar 142 to disengage from the push bar 143. Under the action of gravity, the slide bar 142 slides and is embedded in the connecting bar 141, reducing the number of teeth of the rack 14 until all the slide bars 142 are received and embedded in the connecting bar 141. The processing module 6 controls the first motor 145 to turn off.

[0074] A method for monitoring chicken coughs includes using the above-mentioned chicken shed, and the monitoring method is as follows:

[0075] S1. Respectively collect the call information of the chickens in the cage body 2 and the body temperature information of the chickens in the cage body 2 through the acoustic sensor 4 and the temperature sensor 5, and transmit the collected information to the processing module 6 (variational autoencoder (VAE) model) to train the variational autoencoder (VAE) model;

[0076] S2. Through VAE, learn the latent distribution of the input data, generate a feature representation similar to the input data, use the training process of the call information as a sample to input the first feature monitoring network. When the model error is stable, define the error loss1 of this model as threshold 1. Use the training process of the body temperature information as a sample to input the second feature monitoring network, and define the error loss2 as threshold 2 when the error is stable;

[0077] S3. According to the error between the input sample and the model parameters, the model will output a comparison result with threshold 1 or threshold 2, thereby determining whether the sample is abnormal and sending a corresponding instruction to the warning module 7;

[0078] S4. The warning module 7 issues corresponding warning information according to the received instruction.

[0079] In this solution: Through multi-modal joint monitoring, the health status of chickens is evaluated from two perspectives of call information and body temperature information, improving the monitoring accuracy. Call information can reflect the behavior patterns and health conditions of chickens, while body temperature information provides early warnings of abnormal body temperatures. Combining the two pieces of information can more comprehensively and accurately identify abnormal situations.

[0080] The core goal of the generative model is to learn the overall distribution of the data (i.e., the joint distribution), rather than just learning the conditional relationship between the input data and the labels. This model has powerful modeling capabilities and can capture the potential structures and laws of the data. Especially when dealing with imbalanced data, the generative model shows superior capabilities and can effectively infer the full distribution of the calls and normal body temperatures of normal chickens, thereby identifying fewer abnormal samples. At the same time, the generative model has strong environmental migration capabilities and can adapt to different environmental changes and maintain high performance when the number of training samples is small.

[0081] In this embodiment: The cough sounds of chickens are monitored in real time through the acoustic sensor 4, the call information of the chickens' coughs is collected, and it is saved to the specified path of the terminal.

[0082] Using existing functions, Mel-frequency cepstral coefficients (MFCC) feature extraction is performed on the collected call information to generate a feature map of the audio, convert the feature map into a picture format, and save it in the specified path as the sample data of the first feature monitoring network.

[0083] In this solution: As a commonly used representation method of audio features, MFCC can effectively capture the spectral characteristics of audio signals and has good robustness for the recognition of speech and cough sounds.

[0084] In this embodiment: The body temperature of chickens is monitored in real time through the temperature sensor 5, the infrared thermal imaging map of the abnormal body temperature of chickens is collected, and it is saved to the specified path of the terminal as the sample data of the second feature monitoring network.

[0085] In this solution: Since diseased chickens often show abnormal body temperatures (such as fever), therefore, the infrared thermal imaging map can be used as an auxiliary feature to improve the recognition accuracy of diseased chickens. The thermal imaging map reflects the changes in the surface temperature of the chicken group in real time through infrared technology and can accurately identify chickens with abnormal temperatures.

[0086] In this embodiment: When the error between the input call information and the first feature monitoring network is lower than threshold 1, it indicates that the cough behavior of this chicken is normal; when the error is greater than the threshold, it indicates that this chicken has health problems.

[0087] When the error between the input body temperature information and the second feature monitoring network is lower than threshold 2, it indicates that the body temperature of the chicken is normal. When the error is greater than the threshold, it indicates that the body temperature of the chicken is abnormal and there are health problems.

[0088] In this solution: These two different types of feature maps are respectively input into the Variational Autoencoder (VAE) model for training. VAE is a generative model that can generate feature representations similar to the input data by learning the latent distribution of the input data. For the MFCC feature map, during the training process, it is used as a sample to input into the first feature monitoring network. When the model error is stable, the error loss1 of this model is defined as threshold 1. For the infrared thermal imaging map, the second feature monitoring network adopts a similar training process, and when the error is stable, the error loss2 is defined as threshold 2.

[0089] After the training is completed, two independent feature monitoring networks are obtained. The first feature monitoring network is used for the processing of audio signals, and the second feature monitoring network is used for the analysis of infrared thermal imaging maps. In the test phase, the test set contains normal samples and abnormal samples, corresponding to the different performances of healthy chickens and diseased chickens respectively. The test samples are input into the corresponding networks. According to the error between the input samples and the model parameters, the model will output the comparison result with threshold 1 or threshold 2, so as to judge whether the sample is abnormal.

[0090] Specifically, when the error between the MFCC feature map of the input cough audio and the first feature monitoring network is lower than threshold 1, it indicates that the cough behavior of the chicken is normal; when the error is greater than the threshold, it indicates that the chicken may have health problems and needs further examination. Similarly, the infrared thermal imaging map can identify chickens with abnormal body temperature through the error comparison with the second feature monitoring network. By combining the two types of multimodal data of audio and thermal imaging, this method can effectively improve the accuracy of cough abnormality detection. Through the independent training and analysis of different features by the VAE model, not only the generalization ability of the model is optimized, but also the accurate identification of the cough behavior and abnormal body temperature of chickens can be achieved.
