[0026] In this embodiment, by driving the U-shaped track 111 to rotate horizontally above the base 101, the L-shaped mounting plate 112 can be driven to rotate horizontally above the base 101, and then the experimental animal bound to the bottom plate 115 can be driven to rotate horizontally above the base 101. By driving the bottom plate 115 to rotate vertically on the L-shaped mounting plate 112, the experimental animal bound to the bottom plate 115 can be driven to rotate vertically above the base 101. Combined with the horizontal rotation of the experimental animal above the base 101, the anti-rotational dizziness ability of the experimental animal under centrifugal conditions can be measured. During the rotation of the experimental animal, the visual sensor 10 3 is used to collect visual data formed by the experiment, and it is determined whether the experimental animal has dizziness based on the visual data. When dizziness occurs, the controller 104 is used to control the experimental animal to stop rotating, so as to stop the entire experiment. By measuring the anti-rotation dizziness ability of the experimental animal under centrifugal conditions, an effective measurement of the real coordination ability of the experimental animal is achieved, thereby improving the accuracy of the data obtained from the animal balance experiment, and solving the technical problem that the existing animal balance experiment only measures the balance ability of the experimental animal when measuring with a simple measurement method such as a balance beam, but does not effectively measure the real coordination ability of the experimental animal, thereby reducing the accuracy of the data obtained from the animal balance experiment.

[0027] Wherein, the first servo motor 109 and the first reducer 110 are both fixedly mounted on the base 101, the output shaft of the first servo motor 109 is connected to the input shaft of the first reducer 110, the U-shaped track 111 is fixedly mounted on the output shaft of the first reducer 110, the L-shaped mounting plate 112 is arranged on the U-shaped track 111, the second servo motor 113 and the second reducer 114 are both fixedly mounted on the L-shaped mounting plate 112, the output shaft of the second servo motor 113 is connected to the input shaft of the second reducer 114, the bottom plate 115 is connected to the output shaft of the second reducer 114, the binding belt 116 is arranged on the bottom plate 115, the shading The cover 102 is arranged on the base 101, and completely covers the first rotating device, the second rotating device and the animal plate. The visual sensor 103 is installed on the top of the light shielding cover 102. The controller 104 is connected to the visual sensor 103, the first servo motor 109 and the second servo motor 113 respectively. The controller 104 is located on the base 101. The output shaft of the first servo motor 109 is connected to the input shaft of the first reducer 110, and the U-shaped track 111 is fixedly installed on the output shaft of the first reducer 110, so that the first servo motor 109 can transmit the driving force to the input shaft of the first reducer 110, and the first servo motor 109 is connected to the input shaft of the first reducer 110. The driving force is decelerated, and after deceleration, the decelerated driving force is transmitted to the U-shaped track 111 through the output shaft of the first reducer 110, so that the U-shaped track 111 can be driven to rotate horizontally above the base 101 at a low speed, and the output shaft of the second servo motor 113 is connected to the input shaft of the second reducer 114, and the bottom plate 115 is fixedly installed on the output shaft of the second reducer 114, so that the second servo motor 113 can transmit the driving force to the input shaft of the second reducer 114, and decelerate the driving force at the second reducer 114, and after deceleration, the decelerated driving force is transmitted to the bottom plate 115 through the output shaft of the second reducer 114, so that the U-shaped track 111 can be driven to rotate horizontally above the base 101 at a low speed. The bottom plate 115 rotates vertically above the base 101, the strap 116 can fix the experimental animal on the bottom plate 115, the light shield 102 covers the entire training and measuring equipment, constructs a lightless environment for the experiment, and isolates the heat exchange between the experimental environment and the outside world. The controller 104 is connected to the visual sensor 103, the first servo motor 109 and the second servo motor 113 respectively. The visual sensor 103 (including infrared lighting) is installed on the top of the light shield 102, and its field of view can completely cover the experimental area. It is used to collect visual data formed by the experiment, and judge the direction of the experimental animal's head through machine learning, as well as whether the experimental animal vomits or closes its eyes for a long time during the experiment.If vomiting occurs and the eye closure time is higher than the limit, it is considered that the animal is dizzy. At this time, the judgment result is transmitted to the controller 104, so that the controller 104 will generate corresponding control instructions to control the first servo motor 109 and the second servo motor 113 to stop running, thereby stopping the experiment.

[0028] Secondly, the output shaft of the first servo motor 109 is connected to the input shaft of the first reducer 110 through a gear pair, and the second rotating device is electrically connected to the base 101 through a conductive slip ring.

[0029] Again, the bottom of the U-shaped track 111 is provided with multiple rows of threaded holes, the L-shaped mounting plate 112 is provided with through holes, the L-shaped mounting plate 112 is fixedly mounted on the U-shaped track 111 by screws 117, the U-shaped track 111 is composed of two U-shaped track plates, each U-shaped track plate is evenly distributed with an even number of threaded holes, the L-shaped mounting plate 112 is evenly distributed with through holes, the number of through holes of the L-shaped mounting plate 112 is the same as the number of threaded holes of each U-shaped track plate, and the positions of the through holes of the L-shaped mounting plate 112 are The screw 117 is threadedly connected to the threaded hole of the U-shaped track plate corresponding to the position of the threaded hole of each U-shaped track plate, so that the screw 117 can pass through the through hole of the L-shaped mounting plate 112 and be tightened in the threaded hole of the U-shaped track plate, so that the L-shaped mounting plate 112 is fixedly mounted on the U-shaped track plate, and the two L-shaped mounting plates 112 are fixedly mounted on the two U-shaped track plates respectively, so that the two L-shaped mounting plates 112 can be fixedly mounted on the left and right sides of the U-shaped track 111 respectively.

[0030] Meanwhile, the strap 116 is provided with a Velcro sub-strip 118 and a Velcro main patch 119 , and the experimental animal can be fixed by sticking the Velcro sub-strip 118 and the Velcro main patch 119 together.

[0031] In addition, the flexible display screen 105 is arranged around the U-shaped track 111, and based on the animal head orientation obtained by the visual sensor 103, tracks and displays a specific pattern in the direction of the animal's line of sight. The height of the highest point of the L-shaped mounting plate 112 should be higher than the height of the highest point of the base plate 115 to avoid blocking the line of sight of the experimental animal fixed on the base plate 115, which prevents the experimental animal from viewing the flexible display screen 105.

[0032] Finally, the temperature control device 106 is arranged in the light shield 102 for controlling the temperature in the experimental space, the water spray device 107 is arranged above the animal plate for implementing specific water spray stimulation to the experimental animals, and the host computer 108 is connected to the controller 104 for setting the rotation speed curve of the first rotating device and the second rotating device and the maximum experimental time.

[0033] When using an experimental animal balance training and measurement device of the present embodiment, when measuring the anti-rotational dizziness ability of the experimental animal, the abdomen of the experimental animal is first placed on the base plate 115, and the experimental animal is fixed by sticking the Velcro sub-strip 118 on the strap 116 and the Velcro mother patch 119 on another strap 116 together, and the sticking position of the Velcro sub-strip 118 and the Velcro mother patch 119 on the strap 116 is adjusted, so that experimental animals of different specifications can be fixed.

[0034] After the experimental animal is fixed, the light shield 102 is covered on the base 101, so that the light shield 102 can construct a light-free environment for the experiment and isolate the heat exchange between the experimental environment and the outside world. After that, after setting the rotation speed curve of the first rotating device and the second rotating device and the maximum experimental time through the host computer 108, a start instruction is input to the host computer 108, so that the host computer 108 can transmit the start instruction to the controller 104, so that the controller 104 can control the start of the first servo motor 109 and the second servo motor 113 according to the start instruction.

[0035] By starting the first servo motor 109, the first servo motor 109 can transmit the driving force to the input shaft of the first reducer 110, and reduce the driving force at the first reducer 110. After reduction, the reduced driving force is transmitted to the U-shaped track 111 through the output shaft of the first reducer 110, so that the U-shaped track 111 can be driven to rotate horizontally above the base 101 at a low speed, and then the experimental animal bound to the bottom plate 115 can be driven to rotate horizontally above the base 101 at a low speed. The start-up of the motor 113 enables the second servo motor 113 to transmit the driving force to the input shaft of the second reducer 114, and reduce the driving force at the second reducer 114. After reduction in speed, the reduced driving force is transmitted to the base plate 115 through the output shaft of the second reducer 114, thereby driving the experimental animal bound to the base plate 115 to rotate vertically above the base 101 at a low speed. Combined with the horizontal rotation of the experimental animal above the base 101, the anti-rotational dizziness ability of the experimental animal under centrifugal conditions can be measured.

[0036] During the measurement of the experimental animals' ability to resist rotational dizziness, the temperature in the experimental space is controlled by the temperature control device 106, the water spray device 107 is used to apply specific water spray stimulation to the experimental animals, the visual data formed by the experiment is collected by the visual sensor 103, and the direction of the experimental animal's head and whether the experimental animal vomits or closes its eyes for a long time during the experiment are determined by machine learning. If vomiting occurs and the eye-closing time is higher than the limit, it is considered that the animal is dizzy. At this time, the judgment result is transmitted to the controller 104, so that the controller 104 will generate corresponding control instructions to control the first servo motor 109 and the second servo motor 113 to stop running, thereby stopping the experiment. The flexible display screen 105 tracks and displays a specific pattern in the direction of the animal's line of sight based on the animal's head direction obtained by the visual sensor 103, thereby assisting in measuring the experimental animals' ability to resist rotational dizziness under centrifugal conditions.

[0037] By measuring the ability of experimental animals to resist rotational dizziness under centrifugal conditions, the actual coordination ability of experimental animals can be effectively measured, thereby improving the accuracy of data obtained from animal balance experiments. This solves the technical problem that the existing animal balance experiments, when using simple measurement methods such as balance beams, only measure the balance ability of experimental animals, but fail to effectively measure the actual coordination ability of experimental animals, thereby reducing the accuracy of data obtained from animal balance experiments.

Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiments and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
