The single-plank bridge test uses a bridge of a specific width and length, and the physical fitness and coordination ability of the animal are evaluated based on the time it takes the animal to pass through the bridge or fall from the bridge. However, the existing single-plank bridge test and rotating rod fatigue test are designed with simple movement processes when evaluating animals, resulting in fewer types of data available for analysis and a large grading span, making it difficult to effectively and accurately evaluate the actual situation of the animals.

DETAILED DESCRIPTION
[0016] The specific implementation modes of the present invention are described below so that those skilled in the art can understand the present invention. However, it should be clear that the present invention is not limited to the scope of the specific implementation modes. For those of ordinary skill in the art, as long as various changes are within the spirit and scope of the present invention as defined and determined by the attached claims, these changes are obvious, and all inventions and creations utilizing the concept of the present invention are protected.
[0017] Example 1 like Figure 1-Figure 2 As shown, an active experimental animal physical fitness and coordination ability measuring instrument comprises a base 1, on which an electric roller 2 is arranged, and the electric roller 2 is provided with a torque sensor; One end of the electric roller 2 is set as the starting end of the animal test, and the other end is the end of the test; the end of the test is provided with an animal attracting component, which is used to attract the animal and move the animal from the starting end to the end of the test; The base 1 is also provided with an animal position detection component, which is used to detect the position of the animal on the electric roller 2; It also includes a controller, which is electrically connected to the electric roller 2, the torque sensor and the animal position detection component, and the controller is loaded with a program for executing an active experimental animal physical fitness and coordination ability measurement method.
[0018] The animal attraction component includes a bedding box 3, which is located at one end of the electric roller 2; the bedding box 3 contains bedding of the original breeding environment of the experimental animals. The animal attraction component also includes a triangular cover 4 that is covered on the electric roller 2, the narrower top end of the triangular cover 4 is located at the test start end, and the wider bottom end of the triangular cover 4 is located at the test end end. Animals have an instinct to yearn for small spaces, and small spaces give animals a sense of security. The setting of the triangular cover 4 makes the test end end narrower than the test start end. Combined with the bedding with its own odor, the animal can actively move closer to the test end end. This attraction method can, on the one hand, determine whether the animal has normal instincts after the disease modeling, and whether the modeling affects the animal's instinctive thinking; on the other hand, it can reduce the impact of the animal's possible learning behavior on the evaluation of physical fitness and coordination ability, so that the calculated score can more reasonably evaluate the animal's physical fitness and coordination ability.
[0019] The animal position detection component is an infrared detection array 5 arranged above the electric roller 2.
[0020] The base 1 is also provided with an anti-falling net 7 for catching the experimental animals that fall from the numerically controlled roller device, and preventing the animals from moving around at will after falling from the electric roller 2.
[0021] The surface of the electric roller 2 is provided with an anti-skid layer to ensure that the feet of the animal will not slip when exercising.
[0022] The method for measuring the physical fitness and coordination ability of experimental animals using the above measuring instrument comprises the following steps: S1: Place the animal to be tested on the electric roller 2. At this time, the animal attraction component is not installed. After it adapts for 10 seconds and keeps balance on the electric roller 2, control the electric roller 2 to rotate periodically. The rotation angle of the electric roller 2 and time Satisfies the following formula: ; in, is the maximum rotation angle, is the angular velocity of rotation; When it is positive, the electric roller 2 is in the forward rotation state. When it is a negative value, the electric roller 2 is in a reverse state. The torque sensor is used to collect periodic rotation data, and the friction curve between the foot of the animal to be tested and the surface of the electric roller 2 is calculated and fitted; S2: Install the animal attraction component, rotate the electric roller 2, and set two attitude threshold lines 10 symmetrically on both sides of the axis of the electric roller 2; Figure 4 As shown, the posture threshold line 10 is a virtual line used to cooperate with the animal position detection component. The position of the posture threshold line 10 is related to the friction force and satisfies ;in, is the angle between the attitude threshold line 10 and the vertical line in the cross section along the length direction of the electric roller 2; is the friction coefficient between the animal to be tested and the surface of the motorized roller.
[0023] S3: The animal to be tested is placed at the test start end. Under the attraction of the animal attraction component, the animal to be tested instinctively moves to the test end end. With the assistance of the position detection component, when the contour of the animal to be tested contacts the posture threshold line 10, the speed of the electric roller 2 is determined. ; S4: The electric roller 2 has different speeds within the range, and multiple experiments are performed to obtain the time for the animal to be tested to move from the test start end to the test end corresponding to the different speeds of the electric roller 2, and the speed-time relationship curve is obtained by statistical fitting; the time is determined by the infrared detection array 5. In the specific implementation, a virtual test start line 8 and a test end line 9 are set. Taking mice as an example, Figure 5 As shown in FIG. 8 , the timing starts when the mouse nose passes the test starting line 8. Figure 6 As shown, when the tail of the mouse (excluding the tail) crosses the test end line 9, the timing ends; S5: Perform forward and reverse rotation experiments on the electric roller 2 respectively, and calculate the animal's physical fitness and coordination ability scores according to the following formula : ; in, is the area enclosed by the friction curve and the horizontal axis; is the body mass index of the animal to be tested, and , is the weight of the animal to be tested, in g, is the body length of the animal to be tested, in cm; is the area enclosed by the speed-time relationship curve and the horizontal axis when the electric roller 2 rotates forward; is the area enclosed by the speed-time relationship curve and the horizontal axis when the electric roller 2 is reversed; The time it takes for the animal to move from the start end to the end end of the test when the outline of the animal to be tested touches the posture threshold line 10 when the electric roller 2 rotates forward; It is the time when the outline of the animal to be tested moves from the test start end to the test end end when the electric roller 2 reverses and the outline of the animal to be tested contacts the posture threshold line 10.
[0024] Example 2 like Figure 3 As shown, the difference between this embodiment and embodiment 1 is that the animal position detection component is a camera 6 arranged above the electric roller 2, and the controller is built with an image processing module, and the image processing module is used to extract the image contour of the image taken by the camera 6. When the image processing module is used to perform the physical fitness and coordination ability measurement method, the controller is built with a camera 6 data processing module, and the experimental scene image data is processed by the camera 6 data processing module to obtain the image of the animal, and the animal image contour line is obtained by the existing contour extraction method, and the distance between the animal image contour line and the posture threshold line 10 is used as the deviation distance, and the rotation speed of the electric roller 2 is solved according to the deviation distance, and the time for the animal to be tested to move from the test start end to the test end is extracted according to the experimental scene image data.
