DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] like Figure 1 and Figure 2 As shown, the animal behavior experimental device of the embodiment of the present invention is a comprehensive experimental platform that can flexibly and synchronously adjust the stimulus source 4 and the feeding position, and monitor the animal behavior in real time. The animal behavior experimental device of the embodiment of the present invention includes: a base 1, a box 2, a mounting plate 3, a stimulus source 4, a feeding component 5, an image collector 6, a drive component 7 and a control mainboard 8.

[0022] The box body 2 is installed on the base 1, and a plurality of feeding ports 21 are arranged on the outer side of the box body 2, and the plurality of feeding ports 21 are arranged in sequence along the circumferential direction of the box body 2; the mounting plate 3 is installed on the base 1 and is located below the box body 2, and the stimulation source 4 and the feeding component 5 are both installed on the top surface of the mounting plate 3; the image collector 6 is used to collect images inside the box body 2, and the images include animals and the stimulation source 4; the driving component 7 is installed on the base 1, and the feeding component 5, the image collector 6 and the driving component 7 are all electrically connected to the control main board 8, and the mounting plate 3 is connected to the driving component 7; the control main board 8 controls the movement of the driving component 7, and relative rotation is generated between the box body 2 and the mounting plate 3, so that the stimulation source 4 and the feeding component 5 correspond to any one of the plurality of feeding ports 21, and the feeding component 5 is controlled to extend into the feeding port 21 according to the image.

[0023] The box 2 is mounted on the base 1 to form a closed or semi-closed space for accommodating experimental animals. A plurality of feeding ports 21 are arranged on the outer side of the box 2, and these feeding ports 21 are arranged in sequence along the circumferential direction of the box 2, allowing the feeding assembly 5 to extend into the box 2 from different positions. In addition, the box 2 should be made of a transparent or translucent material to facilitate the image collector 6 to clearly capture the internal situation of the box 2.

[0024] In addition, the mounting plate 3 is mounted on the base 1 and is located below the box 2, for carrying the stimulus source 4 and the feeding assembly 5. The stimulus source 4 is mounted on the top surface of the mounting plate 3, for providing visual, auditory or tactile stimulation to the experimental animals. Among them, the stimulus source 4 can be a magnet or a light source, etc. The feeding assembly 5 is also mounted on the top surface of the mounting plate 3, for providing food or rewards to the experimental animals. Among them, the feeding assembly 5 includes a support, a shell, an electric push rod and a food box, the shell is mounted on the support, the shell is provided with an activity space and an opening connected to the activity space, the electric push rod is installed in the activity space, and the food box is installed on the electric push rod. Driven by the electric push rod, the food box can enter and exit the activity space through the opening. In addition, a feeding port connected to the activity space is also provided on the top of the shell, and food can enter the food box through the feeding port.

[0025] In addition, the image collector 6 can be a camera for collecting images inside the box 2 in real time, including the behavior and position of the animal and the state and position of the stimulus source 4. The image collector 6 is electrically connected to the control mainboard 8, and transmits the collected image data to the control mainboard 8 for processing and analysis. The control mainboard 8, as a control center, is responsible for receiving and processing the image data from the image collector 6, and controlling the actions of the drive component 7 and the feeding component 5.

[0026] The control main board 8 receives the experimental parameter settings, and the driving component 7 rotates the mounting plate 3 to the target position to ensure that the stimulus source 4 and the feeding component 5 correspond to a certain feeding port 21. The control main board 8 starts the image acquisition device 6 to collect image data inside the box 2 in real time. The control main board 8 processes and analyzes the collected image data to identify the behavior pattern and position of the experimental animal. When the experimental animal exhibits a specific behavior (such as approaching a certain feeding port 21), the control main board 8 controls the feeding component 5 to extend into the corresponding feeding port 21 to provide food or rewards to the experimental animal. In addition, the control main board 8 can save the image data and behavior data collected during the experiment to the memory for subsequent analysis and research.

[0027] In this way, through the animal behavior experimental device of the embodiment of the present invention, the stimulation source 4 and the feeding position can be flexibly adjusted, the behavior patterns of experimental animals can be monitored and analyzed in real time, and a powerful experimental tool can be provided for research in the fields of animal behavior and the like.

[0028] like Figure 1 and Figure 2As shown, the animal behavior experiment device also includes a positioning column 9 and a first infrared reflection type photoelectric position detection component 10, the first infrared reflection type photoelectric position detection component 10 is electrically connected to the control main board 8, the positioning column 9 is installed on the box 2, and is used to mark the position of the feeding port 21 on the box 2, and the first infrared reflection type photoelectric position detection component 10 is installed on the top surface of the mounting plate 3. When the box 2 and the mounting plate 3 rotate relative to each other, the first infrared reflection type photoelectric position detection component 10 is opposite to the positioning column 9 to generate the first positioning information, and the control main board 8 is used to determine that the stimulus source 4 and the feeding component 5 correspond to one of the multiple feeding ports 21 according to the first positioning information. Among them, the stimulus source 4 corresponds to the feeding port 21 means that the stimulus source 4 corresponds to the bottom of the box 2 and is close to the feeding port 21.

[0029] Among them, the positioning column 9 is installed on the box body 2 to mark the position of the feeding port 21 on the box body 2. Through the positioning column 9, the specific position of each feeding port 21 can be accurately known, providing a reference for subsequent automatic alignment. Exemplarily, each feeding port 21 is provided with a corresponding positioning column 9. The positioning column 9 is usually installed at or near the edge of the feeding port 21 of the box body 2 to ensure that the first infrared reflection type photoelectric position detection component 10 can accurately detect its position. Exemplarily, the positioning column 9 is located at the bottom of the box body 2 and corresponds to the feeding port 21.

[0030] In practical applications, the first infrared reflection type photoelectric position detection component 10 is installed on the top surface of the mounting plate 3 to detect the position of the positioning column 9, thereby generating the first positioning information. The first infrared reflection type photoelectric position detection component 10 is electrically connected to the control main board 8, and transmits the generated first positioning information to the control main board 8 for processing. In this way, through the combined use of the positioning column 9 and the first infrared reflection type photoelectric position detection component 10, the feeding port 21 can be accurately positioned, thereby improving the accuracy and reliability of the experiment.

[0031] like Figure 1 and Figure 2 As shown, the animal behavior experiment device further includes a mounting rod 11, the mounting rod 11 includes a vertical portion and a horizontal portion, the vertical portion is mounted on the base 1, and the image collector 6 is mounted on the horizontal portion.

[0032] It should be noted that the mounting rod 11 includes a vertical portion and a horizontal portion, the vertical portion is used to be mounted on the base 1, and the horizontal portion is used to mount the image collector 6. In this way, the position and angle of the image collector 6 can be flexibly adjusted to ensure that the image inside the box 2 can be clearly captured, including the behavior and position of the experimental animal and the state and position of the stimulus source 4.

[0033] like Figure 1 and Figure 2As shown, the animal behavior experiment device also includes a second infrared reflection type photoelectric position detection component 14, which is electrically connected to the control main board 8, and the second infrared reflection type photoelectric position detection component 14 is installed on the top surface of the mounting plate 3. When relative rotation occurs between the box body 2 and the mounting plate 3, the second infrared reflection type photoelectric position detection component 14 is opposite to the vertical portion to generate second positioning information, and the control main board 8 is used to determine that the feeding port 21 is the starting feeding port according to the first positioning information and the second positioning information.

[0034] When relative rotation occurs between the box body 2 and the mounting plate 3, the second infrared reflection type photoelectric position detection component 14 moves relative to the vertical portion, and generates second positioning information when the second infrared reflection type photoelectric position detection component 14 is relative to the vertical portion. The second positioning information is combined with the first positioning information received by the control main board 8 to determine the position of the starting feeding port. Specifically, similar to the first infrared reflection type photoelectric position detection component 10, the second infrared reflection type photoelectric position detection component 14 also includes an infrared emitting element and an infrared receiving element. The infrared emitting element emits infrared light, and when the light encounters the vertical portion, it is reflected back to the infrared receiving element. In other words, the position of the target object is detected by the infrared reflection principle, and the position information is converted into an electrical signal and output to the control main board 8.

[0035] Specifically, the first infrared reflection type photoelectric position detection component 10 and the second infrared reflection type photoelectric position detection component 14 are located on the front and back sides of the support, and the first infrared reflection type photoelectric position detection component 10, the second infrared reflection type photoelectric position detection component 14, the feeding component 5 and the stimulation source 4 are in the same vertical plane. When the first infrared reflection type photoelectric position detection component 10 moves to the positioning rod, the first infrared reflection type photoelectric position detection component 10 generates a low-level digital signal for locating the position of the feeding port 21. When the first infrared reflection type photoelectric position detection component 10 passes the positioning rod, it generates a low-level digital signal to be transmitted to the lower computer 81, and when the second infrared reflection type photoelectric position detection component 14 passes the support rod 12, it generates a low-level digital signal to be transmitted to the lower computer 81, and the lower computer 81 locates the starting feeding port according to the two low-level digital signals.

[0036] like Figure 1 and Figure 2 As shown, the animal behavior experiment device of the embodiment of the present invention further includes a support rod 12, a mounting plate 3 is provided with a through hole, one end of the support rod 12 is mounted on the base 1, and the other end of the support rod 12 passes through the through hole and is connected to the bottom of the box 2, and the driving component 7 is connected to the mounting plate 3 to drive the mounting plate 3 to rotate relative to the box 2. Among them, the mounting plate 3 is rotatably connected to the support rod 12.

[0037] It should be noted that one end of the support rod 12 is mounted on the base 1, and the other end passes through the through hole on the mounting plate 3 and is connected to the bottom of the box 2. In this way, not only does the box 2 provide additional support, but also the stability of the box 2 and the mounting plate 3 during relative rotation is ensured. The drive assembly 7 can accurately control the rotation angle and speed of the mounting plate 3 according to the instructions of the control main board 8.

[0038] like Figure 1 and Figure 2 As shown, the driving assembly 7 includes a driving motor 71, a transmission member 72 and an external gear rotary bearing 73. The mounting plate 3 is mounted on the support rod 12 via the external gear rotary bearing 73. The driving motor 71 is coupled to the transmission member 72 by power, and the transmission member 72 is meshed with the external gear rotary bearing 73. The transmission member 72 may be a gear, and the driving motor 71 may be a stepping motor.

[0039] It should be noted that the inner ring of the external tooth rotary bearing 73 is installed on the support rod 12, the mounting plate 3 is installed on the top surface of the outer ring of the external tooth rotary bearing 73, the gear is installed on the output shaft of the drive motor 71, and the gear is meshed with the gear teeth of the outer ring of the gear rotary bearing.

[0040] Specifically, the drive motor 71 is started, and the motor transmits the rotational power to the external gear rotary bearing 73 through the transmission member 72. After receiving the power, the external gear rotary bearing 73 drives the mounting plate 3 to rotate relative to the support rod 12. During the experiment, the speed and direction of the drive motor 71 can be adjusted as needed to control the rotation speed and direction of the mounting plate 3.

[0041] like Figure 1 and Figure 2 As shown, the animal behavior experiment device of the embodiment of the present invention further includes a plurality of columns 13, which are mounted on the base 1 and used to support the external gear rotary bearing 73. It should be noted that the plurality of columns 13 are arranged circumferentially relative to the mounting plate 3, and the columns 13 can be used to support the inner ring and the outer ring of the external gear rotary bearing 73.

[0042] like Figure 1 and Figure 2 As shown, the animal behavior experiment device of the embodiment of the present invention further includes: an interaction module, which is electrically connected to the control mainboard 8 and is used to transmit control signals to the control mainboard 8 and / or output animal behavior experiment information.

[0043] It should be noted that the interactive module can receive control instructions from the experimenter, such as start, stop, and adjust experimental parameters, and convert these instructions into control signals and transmit them to the control mainboard 8. The control mainboard 8 adjusts the working state of the experimental device, such as rotation speed, rotation direction, etc., according to the received control signal. The interactive module can collect and process experimental data from the experimental device in real time, such as the behavioral response of animals, etc. The processed experimental data is presented to the experimenter in an intuitive and easy-to-understand manner, such as through a display screen, printed reports, etc.

[0044] Specifically, the interactive module adopts a touch screen design, and the experimenter can input control instructions by touching the buttons or icons on the screen. At the same time, the touch screen can also display real-time data, charts and reports during the experiment, making it convenient for the experimenter to view and analyze the experimental results at any time.

[0045] The interactive module uses wireless communication technology, such as Wi-Fi, Bluetooth, etc., to connect to the control mainboard 8 of the experimental device. The experimenter can send control instructions to the interactive module remotely through mobile devices such as smart phones and tablets. After receiving the instructions, the interactive module converts them into control signals and transmits them to the control mainboard 8, and returns the experimental results to the mobile device in real time. In this way, the experimenter can perform remote control at a place far away from the experimental device, which improves the convenience and flexibility of the experiment.

[0046] The interactive module in the animal behavior experimental device of the embodiment of the present invention realizes the transmission of control signals and the output of animal behavior experimental information through electrical connection with the control main board 8. The flexibility and user-friendliness of the experimental device are improved, so that the experimenter can conveniently control the experimental process and obtain experimental data. At the same time, according to different experimental requirements and application scenarios, different types of interactive modules can be selected to achieve the best experimental effect.

[0047] like Figure 3 As shown, the animal behavior experimental method of the embodiment of the present invention includes: S100, controlling the driving assembly 7 to move, causing relative rotation between the box body 2 and the mounting plate 3, so that the stimulation source 4 and the feeding assembly 5 correspond to the target feeding port 21 among the multiple feeding ports 21.

[0048] S200, controlling the feeding assembly 5 to extend into the feeding port 21 according to the image acquired by the image collector 6, wherein the positions of the animal and the stimulus source 4 in the image overlap and meet the target time.

[0049] Specifically, the control main board 8 includes an upper computer 82 and a lower computer 81. When the experiment starts, the upper computer 82 sends a start command to the lower computer 81. At this time, the lower computer 81 performs the action of locating the initial feeding port (cooperating with the first infrared reflection type photoelectric position detection component 10 and the second infrared reflection type photoelectric position detection component 14). After locating the initial feeding port, the lower computer 81 sends a command to find the initial feeding port to the upper computer 82. After receiving the command, the upper computer 82 randomly selects a feeding port 21 and sends it to the lower computer 81. The lower computer 81 performs the positioning of the selected feeding port 21 (only using the first infrared reflection type photoelectric position detection component 10 for positioning). After reaching the position of the feeding port 21, the lower computer 81 sends an arrival command to the upper computer 82, and the upper computer 82 reads the image information generated by the image collector 6 for analysis. Image analysis uses a fine-tuned lightweight target detection model (such as Yolo-tiny, faster RCNN, etc.) to automatically identify animals. When the animal position overlaps with the position of the stimulus source 4 for a certain period of time, it is determined that the animal has found the stimulus source 4, and the upper computer 82 sends a reward instruction to the lower computer 81. The lower computer 81 drives the feeding component 5 to enter the feeding port 21. After feeding for a certain period of time, the feeding component 5 retracts, and the lower computer 81 sends a reward completion instruction to the upper computer 82. The upper computer 82 randomly selects the feeding port 21 again and sends it to the lower computer 81, and enters the next training cycle. If the animal does not find the feeding port 21 within a specified training cycle, the upper computer 82 randomly selects the feeding port 21 again and sends it to the lower computer 81, and enters the next training cycle. The total experimental duration can be set before the experiment. If the experimental duration is greater than or equal to the set total experimental duration before entering the next training cycle, the entire experiment is terminated.

[0050] Among them, the specific implementation method of the lower computer 81 locating the target feeding port 21 according to the low-level digital signal is as follows: the mounting plate 3 initially rotates counterclockwise, and when the first infrared reflection type photoelectric position detection component 10 and the second infrared reflection type photoelectric position detection component 14 simultaneously generate low-level signals, the starting feeding port is located. According to the feeding port 21 randomly selected by the upper computer 82, if it is the starting feeding port, it has been successfully located; if it is another feeding port 21, it rotates clockwise and reaches the feeding port 21 according to the low-level signal of the first infrared reflection type photoelectric position detection component 10. In each experiment, the lower computer 81 locates the feeding port 21 according to this algorithm, which can ensure that the rotation angle of the mounting plate 3 is between 0° and 360° (can only rotate once at most) to prevent the cable from being entangled.

[0051] It can be understood that the total experimental time, the duration of a training cycle, the feeding time, and the overlap time between the animal and the stimulus source 4 can be modified through the upper computer 82 interface or the interactive module, where the feeding time is sent to the lower computer 81 through the serial port for driving the feeding component 5.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
