Description

Technical Field

[0001] The present invention relates to the field of animal experiment technology, and in particular to an intelligent management method and an intelligent processing system for experimental animals. Background Art

[0002] Disease animal models play an irreplaceable role in medicine and basic research. They can simulate the development process and clinical manifestations of the disease, reveal the key molecular mechanisms, signaling pathways and pathogenic factors in pathophysiological processes, and provide a scientific basis for the design and optimization of treatment methods. In addition, they can also effectively evaluate the efficacy and safety of potential drugs, and be used to test the effectiveness of new diagnostic tools.

[0003] During the establishment and research of animal models, it is often necessary to collect animal body fluid samples, including feces and urine. However, since experimental animals are not domesticated, their excretion habits are uncertain, and they have abnormal behaviors such as aggression, it is difficult to ensure the safety of experimenters, which brings difficulties to sample collection. In addition, affected by the environment in which the experimental animals are located, the quality of the collected samples is unstable and easily disturbed by factors such as time and environment, which seriously affects the research results.

[0068] Figure 2 This is a schematic diagram of the structure of an intelligent processing system for experimental animals according to Example 3 of the present invention. DETAILED DESCRIPTION

[0069] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0070] Laboratory animals: Laboratory animals are non-domesticated animals purchased from suppliers, not artificially domesticated or bred in laboratories. They are used for a variety of experimental purposes such as scientific research, education, disease model creation, and environmental impact assessment.

[0071] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0072] Example 1

[0073] See also Figure 1 The present embodiment provides an intelligent management method for experimental animals, which is used to manage experimental animals in an untamed stage. The method comprises:

[0074] Step S10, obtaining in real time the video stream of the experimental animal to be monitored, and obtaining in real time the environmental parameters of the activity area and excretion area of ​​the experimental animal;

[0075] Step S20, determining whether the current experimental animal is in a state of waiting to defecate according to the posture information and / or behavior pattern of the experimental animal in the video stream;

[0076] Step S30: if it is determined that the animal is in the state of waiting to excrete, an excretion guiding control instruction is sent to the excretion guiding device, so that the excretion guiding device sends guiding information to the designated excretion area according to the excretion guiding control instruction, and the guiding information is used to guide the experimental animal to move to the designated excretion area;

[0077] Step S40: if the experimental animal has completed excretion in the designated excretion area, a cleaning mode is obtained according to the environmental parameters of the excretion area when there is no excrement and the environmental parameters of the excretion area when there is excrement, as well as the state of the excrement, and the obtained cleaning mode is sent to the automatic cleaning device, so that the automatic cleaning device automatically cleans according to the cleaning mode;

[0078] And / or, the cleaning mode is sent to the sterile collection device, so that the sterile collection device reasonably collects the excrement according to the cleaning mode, and after the collection, the collection completion information is sent to the automatic cleaning device, so that the automatic cleaning device automatically cleans according to the cleaning mode.

[0079] In this embodiment, the video stream of the experimental animal to be monitored in step S10 is obtained in real time by a camera or other video capture device. These cameras are usually installed at different locations in the activity area and excretion area of ​​the experimental animal so as to capture the behavior of the animal from multiple angles.

[0080] Furthermore, environmental parameters are acquired through sensors (such as temperature sensors, humidity sensors, pressure sensors, etc.).

[0081] In this embodiment, after step S30 and before step S40, the intelligent management method of the present invention further includes:

[0082] Step S30a, if the experimental animal completes defecation in the designated defecation area, a reward instruction is sent to the reward device, so that the reward device sends reward information to the experimental animal according to the reward instruction, and the reward information is used to reinforce the behavior of the experimental animal to defecate in the designated defecation area;

[0083] The reward information includes: giving reward food to the experimental animals, or playing happy music to the experimental animals, or giving toys to the experimental animals;

[0084] For example, assuming the experimental animal is a rabbit, through the video camera we can see that it has completed excretion in the designated excretion area. At this time, a reward instruction is sent to the reward device. According to the reward instruction, the reward device can put a small piece of fresh carrot into the rabbit's activity area as a reward. After the rabbit smells the carrot, it quickly comes to the activity area to eat. After this process is repeated many times, the rabbit can gradually learn that it can only get food rewards if it excretes in the designated excretion area.

[0085] In addition, it is also possible to determine whether the experimental animal has completed excretion through a pressure sensor installed in the excretion area. When the pressure sensor in the excretion area detects a change in pressure, it means that the experimental animal is already in the excretion area and has started to excrete. When the pressure sensor in the excretion area detects that the pressure no longer changes, it means that the experimental animal has completed excretion, and a reward instruction is sent to the reward device.

[0086] Before step S20, the method further includes:

[0087] Collecting in advance the posture information of various states of experimental animals to be excreted, and collecting in advance the behavior patterns of various states of experimental animals to be excreted; obtaining a time prediction model for estimating the excretion interval based on the posture information, behavior patterns and historical excretion data of experimental animals;

[0088] The behavior pattern includes one or more of the following: activity frequency, movement trajectory, dwell time, and body posture.

[0089] In the specific implementation process, machine learning algorithms, especially support vector machines or deep neural networks, are used to analyze and learn posture information and behavior patterns, so as to realize the automatic recognition and classification of animal pre-excretion behavior. On this basis, the excretion data of historical experimental animals is further used, combined with the behavior recognition results, and the time prediction model is trained through advanced statistical methods such as cross-validation. This model can predict the exact time of the next excretion of the animal based on the animal behavior data collected in real time.

[0090] In this embodiment, step S20 includes:

[0091] Extract key frames from the video stream, binarize the key frames, and obtain a binarized image; compare the binarized image with pre-collected posture information, and when the similarity is greater than a first specified threshold, determine that the current experimental animal is in a state to be excreted; and adjust the first specified threshold according to actual conditions to improve the accuracy of the judgment.

[0092] Specifically, advanced image processing and video analysis technologies are used to conduct in-depth analysis of video data and extract key frames including activity frequency, motion trajectory, dwell time, and body posture.

[0093] Binarization processing converts the extracted key frames into images with only black and white colors, thereby simplifying the image, highlighting the main features, and facilitating subsequent feature extraction and comparison.

[0094] Alternatively, a self-reinforcement learning model is used to learn the behavioral patterns of various states of waiting for excretion of experimental animals collected in advance, and the learned self-reinforcement learning model is used to identify the state of the current experimental animal to determine whether the current experimental animal is in the state of waiting for excretion; the self-reinforcement learning model is a model that adjusts and optimizes while learning;

[0095] The self-improvement learning model can continuously adjust and optimize its own strategies during the learning process. Specifically, starting from the initial state, each time a new behavior pattern is observed, the model will try to predict whether the pattern indicates that the animal is in a state of waiting to defecate; if the model's prediction is consistent with the actual situation (that is, the animal has indeed defecate), the model will adjust its internal parameters based on positive feedback to increase the probability of making correct predictions in the future; conversely, if the prediction is wrong, the model will adjust its internal parameters based on negative feedback to reduce the occurrence of wrong predictions. Through the process of continuous trial and error and self-correction, it gradually learns the behavior pattern that can accurately identify the state of waiting to defecate.

[0096] The self-improvement learning model is trained and optimized through a large amount of behavioral data of experimental animals in the state of waiting to defecate collected in advance, including various posture information and behavioral patterns, such as activity frequency, movement trajectory, dwell time and body posture.

[0097] In actual applications, when judging whether the current experimental animal is in a state waiting to defecate, the real-time video stream is input into the trained self-reinforcement learning model, and the self-reinforcement learning model will output a signal, which is whether the current experimental animal is in a state waiting to defecate.

[0098] Alternatively, whether the current experimental animal is in a state of waiting to defecate is determined based on the posture information and behavior pattern of the experimental animal in the video stream and a pre-acquired time prediction model of the experimental animal.

[0099] The time training model can predict the time of the next defecation of an animal based on the animal behavior data collected in real time.

[0100] Specifically, step S30 also includes:

[0101] If it is determined that the patient is in the state of waiting to excrete, an excretion guiding control instruction is sent to the excretion guiding device, and an alarm message is sent to the manager;

[0102] The excretion guidance control instruction includes: olfactory guidance information of a specific odor to which the current experimental animal is sensitive.

[0103] In this embodiment, if it is determined that the animal is in the state of waiting to excrete, an alarm message is sent to the manager, which can be done in a variety of ways, such as sending an email, text message or push notification to the manager's mobile phone application. The alarm message will include the current location information of the animal and the activation status of the excretion guidance, so that the manager can understand the situation in time.

[0104] At the same time, the excretion guidance control command activates multiple components in the excretion guidance device. For example, if the experimental animal is sensitive to a certain smell, the smell is released to guide the experimental animal to move toward the excretion area through the sense of smell. In addition, the ground vibration can be activated at the same time as the smell is released, and the animal is alerted by a slight vibration signal and further guided in the direction of its movement. These comprehensive guidance measures are designed to take advantage of the animal's instinctive response, so that it can quickly identify the excretion area and actively go to the area to complete excretion.

[0105] During the specific implementation process, other devices such as ground heating devices may also be provided to heat the ground temperature in the activity area and drive the experimental animals into the excretion area for excretion.

[0106] In this embodiment, the environmental parameters include one or more of the following: space temperature parameters, space humidity parameters, viscosity / dryness of excrement in the excretion area, and volume / weight of excrement.

[0107] In this embodiment, step S40 includes:

[0108] According to the feedback from the pressure sensor in the excretion area, it is determined that the experimental animals have completed excretion in the designated excretion area;

[0109] When the air temperature parameter is greater than 20° C., the air humidity parameter is greater than the first humidity value, the viscosity of the excrement in the excretion area is less than the first viscosity, and the weight of the excrement is greater than the first weight, the deep cleaning mode is selected;

[0110] When the air temperature parameter is greater than 20° C., the air humidity parameter is less than the first humidity value, the viscosity is greater than the first viscosity, and the weight of the excrement is greater than the first weight, the medium cleaning mode is selected;

[0111] When the air temperature parameter is greater than 20° C., the air humidity parameter is greater than the first humidity value, the viscosity is greater than the first viscosity, and the weight of the excrement is less than the first weight, a light cleaning mode is selected;

[0112] The deep cleaning mode, the medium cleaning mode and the light cleaning mode have different cleaning frequencies and different air volumes.

[0113] Specifically, the first humidity value, the first viscosity, and the first weight are determined according to the species of the experimental animal.

[0114] In the specific implementation process, the cleaning strategy is adjusted according to the specific conditions of the environmental parameters: if the ambient temperature is too high or the humidity is insufficient, the decomposition of excrement may be accelerated, producing odor or breeding bacteria; if the amount of excrement is too large, in order to ensure that the excrement can be removed in time to avoid pollution to the environment; at the same time, the viscosity and dryness of the excrement also affect the choice of cleaning mode. For drier excrement, more frequent flushing may be required, while for sticky excrement, specific detergents may be required to effectively decompose and remove it.

[0115] For example, when the experimental animal is a rabbit, the first humidity value is set to 40%, the first weight is set to 30 grams, and the first viscosity is set to 5. The viscosity is the ratio of the viscosity of the excrement to the viscosity of water. When the viscosity is greater than 5, the excrement is in a dry state. At this time, there are:

[0116] When the air temperature is greater than 20°C, the air humidity is greater than 40%, the viscosity of the excrement in the excretion area is greater than 5, and the weight of the excrement is greater than 30 grams, select the deep cleaning mode;

[0117] When the air temperature is greater than 20°C, the air humidity is less than 40%, the viscosity is less than 5, and the weight of the excrement is greater than 30g, select the medium cleaning mode;

[0118] When the air temperature parameter is greater than 20° C., the air humidity is greater than 40%, the viscosity is less than 5, and the weight of the excrement is less than 30 g, the light cleaning mode is selected.

[0119] Among them, the deep cleaning mode is: use a higher pressure water flow for flushing and spray an appropriate amount of detergent, and the cleaning time is 3 minutes; the medium cleaning mode is: use moderate water pressure for flushing, spray a small amount of detergent, and the cleaning time is set to 2 minutes; the light cleaning mode is: only start the flushing component, use lower pressure for flushing, and the cleaning time is set to 1 minute.

[0120] The intelligent management method of experimental animals in this embodiment can not only improve the credibility and accuracy of scientific research results, but also reduce the cost and labor intensity of manual operation, and improve the efficiency of environmental sanitation management. In addition, the introduction of the excretion guidance mechanism and the reward mechanism can actively reinforce the animals' excretion behavior, stimulate their autonomy, help establish good excretion habits, promote animal health and comfort, and also reduce manual operation and ensure the safety of experimenters. Finally, this embodiment can adjust different strategies according to different experimental animals, realize intelligent management and personalized adaptation, and improve the versatility and flexibility of the method.

[0121] Example 2

[0122] This embodiment provides an intelligent management method for experimental animals, including:

[0123] Step S10, obtaining in real time the video stream of the experimental animal to be monitored, and obtaining in real time the environmental parameters of the activity area and excretion area of ​​the experimental animal;

[0124] Step S20, determining whether the current experimental animal is in a state of waiting to defecate according to the posture information and / or behavior pattern of the experimental animal in the video stream;

[0125] Step S30: if it is determined that the animal is in the state of waiting to excrete, an excretion guiding control instruction is sent to the excretion guiding device, so that the excretion guiding device sends guiding information to the designated excretion area according to the excretion guiding control instruction, and the guiding information is used to guide the experimental animal to move to the designated excretion area;

[0126] Step S40: if the experimental animal has completed excretion in the designated excretion area, a cleaning mode is obtained according to the environmental parameters of the excretion area when there is no excrement and the environmental parameters of the excretion area when there is excrement, as well as the state of the excrement, and the obtained cleaning mode is sent to the automatic cleaning device, so that the automatic cleaning device automatically cleans according to the cleaning mode;

[0127] And / or, the cleaning mode is sent to the sterile collection device, so that the sterile collection device reasonably collects the excrement according to the cleaning mode, and after the collection, the collection completion information is sent to the automatic cleaning device, so that the automatic cleaning device automatically cleans according to the cleaning mode.

[0128] The intelligent management method in this embodiment is the same as the method in Embodiment 1, and will not be described again here. This embodiment only describes step S30 in detail.

[0129] Specifically, in this embodiment, the experimental animals are guided to defecate in the defecation area through olfactory guidance.

[0130] Specifically, olfactory guidance is achieved using a specific odor release device, and the specific release amount and type of odor released by the odor release device depend on different factors, including the type of experimental animals, the experimental environment, etc.

[0131] For example, taking mice as an example, mice are highly sensitive to the smell of excrement of animals of the same species as themselves, so the smell released by the smell release device at this time is the smell of the excrement of animals of the same species as the mice themselves.

[0132] Furthermore, by observing the behavioral feedback of the animals during the redirection process (such as the length of stay, the number of times they approach the excretion area, etc.), the amount of odor released can be dynamically adjusted. For example, if the rabbit does not immediately go to the excretion area after smelling the odor, the concentration of the odor can be appropriately increased or replaced with a stronger odor.

[0133] In addition, the specific release amount of the odor release device is also related to the experimental environment. For example, in a well-ventilated environment, more odors are needed to maintain the guiding effect; while in a closed environment, the odor release amount can be appropriately reduced to avoid excessive stimulation.

[0134] In this embodiment, a floor vibrator may be provided to guide excretion through floor vibration; and the vibration intensity needs to be adjusted according to the size and sensitivity of the experimental animal.

[0135] For example, for mice, because mice are more sensitive to vibrations, a low-frequency, low-intensity vibration mode can be used. This mode can avoid over-stimulating the mice while ensuring that they can be guided to the excretion area. For rabbits, a high-frequency, high-intensity vibration mode can be used. Because rabbits are larger in size and less sensitive to vibrations, this mode can better guide rabbits to the excretion area.

[0136] Similarly, the vibration pattern can be adjusted dynamically by observing the animal's behavioral feedback during the vibration guidance process. For example, if the rabbit does not respond to the current vibration pattern, you can try adjusting the frequency and intensity of the vibration.

[0137] At the same time, the vibration mode can also be adjusted according to the specific requirements of the experimental environment. For example, in a noisy environment, a higher vibration intensity may be required to ensure that the animal can perceive the vibration signal; while in a quiet environment, the vibration intensity can be appropriately reduced.

[0138] The intelligent management method of this embodiment can automatically adjust the guidance parameters according to factors such as the type of experimental animals and the experimental environment to achieve the best guidance effect.

[0139] Through the above-mentioned guidance mechanism, experimental animals can be effectively guided to defecate in designated excretion areas, thereby improving the accuracy and efficiency of scientific research experiments on experimental animals, and at the same time providing a healthier and more comfortable living environment.
