[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention is equipped with a sensor module. The sensor module includes pressure sensors, displacement sensors, and horizontal sensors evenly embedded at the bottom of the sensing pad, as well as acceleration sensors embedded at the bottom edge and the center of the sensing pad. The sensor module can capture various physical parameter changes during the walking process of animals in all directions and with high precision. The pressure sensors, displacement sensors, horizontal sensors, and acceleration sensors work together to accurately measure the pressure distribution, step length, step frequency, gait stability of the animal's foot, as well as the tilt and acceleration data of the sensing pad, providing detailed and accurate data support for the fields of scientific research, veterinary diagnosis, and animal ethology.

This calibration method eliminates the errors and drifts of the sensors themselves, improving the accuracy and credibility of the overall data of the gait tracking detector. The automated and high-precision gait tracking detector reduces the workload of manual observation and recording, improving the research efficiency. Researchers can collect a large amount of data faster and carry out subsequent data processing and analysis work. Therefore, the problems of low data acquisition accuracy, insufficient reliability and comprehensiveness, and low research efficiency of the gait tracking detector can be solved.

[0016] 2. The present invention is equipped with a support module. The support module includes an elastic foam skeleton layer connected to the bottom of the induction pad. The bottom of the elastic foam skeleton layer is connected to a silica gel skeleton layer, and the bottom of the silica gel skeleton layer is connected to an ABS anti-corrosion skeleton layer. The signal amplification and conversion circuit and the circuit board are embedded in the top of the ABS anti-corrosion skeleton layer. The bottom of the ABS anti-corrosion skeleton layer is connected to an aluminum alloy skeleton layer. The elastic foam skeleton layer not only provides the necessary buffering effect, reducing the direct impact on the sensor when the animal walks, but also helps to maintain the flatness of the induction pad, thereby improving the measurement accuracy. At the same time, the signal amplification and conversion circuit and the circuit board are embedded in the top of the ABS anti-corrosion skeleton layer, which helps to reduce electromagnetic interference and signal attenuation, ensuring the stability and reliability of signal transmission. The ABS anti-corrosion skeleton layer has good anti-corrosion performance, which can resist the erosion of moisture and acid-base corrosive substances, protecting the internal electronic components from damage. Combined with the design of the waterproof rubber shell, the entire gait tracking detector has excellent waterproof performance and can work stably in humid or rainy environments. The use of the aluminum alloy skeleton layer provides sufficient strength while also reducing the overall weight of the gait tracking detector, making the gait tracking detector more convenient to carry and install, which is particularly important for researchers who need to conduct animal gait tracking at different locations. Through the multi-layer structure design of the support module, the structural stability and durability of the entire gait tracking detector in complex environments are ensured. It can effectively resist the influence of external shocks, vibrations, and corrosive environments, extend the service life of the gait tracking detector, and can adapt to a variety of different application scenarios, including laboratory environments, field research, and livestock production. It can work stably under various complex conditions, providing accurate and reliable gait data for scientific researchers. Therefore, it can solve the problems of insufficient structural stability and durability of the gait tracking detector, improve signal stability, anti-corrosion and waterproof performance, achieve weight portability, and multi-scenario adaptability.

[0017] 3. The present invention is equipped with a waterproof rubber housing, heat dissipation through-holes, dust-proof grilles and dust-proof nets, a waterproof breathable membrane, a waterproof coating, suction cups and striped anti-slip pads. The use of the waterproof rubber housing in combination with the waterproof coating provides excellent waterproof performance for the gait tracking detector, ensuring that the gait tracking detector can operate normally in humid or rainy environments, preventing internal electronic components from being damaged by moisture. At the same time, the dust-proof grilles and dust-proof nets arranged inside the heat dissipation through-holes, and the design with the dust-proof grille density greater than that of the dust-proof net effectively prevent the entry of dust and fine particles, protecting the internal components from contamination and extending the service life of the gait tracking detector. Moreover, the design of the heat dissipation through-holes allows the heat generated during the long-term operation of the gait tracking detector to be dissipated in a timely manner, avoiding performance degradation or damage caused by overheating. The use of the waterproof breathable membrane allows air circulation while maintaining waterproof performance, further improving the heat dissipation efficiency. The evenly arranged suction cups and striped anti-slip pads at the bottom of the gait tracking detector increase the friction between the gait tracking detector and the ground, effectively preventing the sliding or displacement of the gait tracking detector during use and ensuring the stability and accuracy of the measurement. By comprehensively considering multiple aspects such as waterproofing, dust-proofing, heat dissipation and anti-slip, the high-precision induction pad type animal gait tracking detector of the present application demonstrates strong multi-environment adaptability. Whether it is an indoor laboratory environment or an outdoor complex and changeable natural environment, it can maintain a stable working state, providing reliable data support for scientific researchers. At the same time, the design of the dust-proof grilles and dust-proof nets makes the cleaning and maintenance of the gait tracking detector easier. When cleaning is required, the dust-proof grilles and dust-proof nets can be conveniently removed for cleaning, thereby maintaining the cleanliness and performance of the gait tracking detector. Therefore, it can solve the problems of limited waterproof and dust-proof protection ability, poor heat dissipation breathability and anti-slip stability, and inconvenient equipment maintenance and servicing of the gait tracking detector.

[0018] 4. The present invention realizes the stable installation and fixation of the gait tracking detector on the measurement plane by installing the first fixing block, the first magnetic attraction plate, the gasket, the second magnetic attraction plate, the second L-shaped fixing block and the extension plate, ensuring that the gait tracking detector will not shift or shake during the animal's walking process, thus guaranteeing the accuracy and reliability of the gait tracking data. The design of the first magnetic attraction plate and the second magnetic attraction plate enables the gait tracking detector to be easily adsorbed, while the second L-shaped fixing block and the extension plate provide additional fixing points and supports, enabling the gait tracking detector to be firmly fixed by bolts on non-magnetic or uneven surfaces. This flexibility allows the gait tracking detector to adapt to a variety of different measurement environments and conditions. At the same time, the design of the magnetic attraction plate makes the installation and disassembly of the gait tracking detector more convenient and fast, without the need for complex tools or operations. The through connection of the bolts also ensures the firmness of the fixation, enabling the installation or disassembly process to be completed quickly when needed. The design of the extension plate provides additional installation points and space for the detector to meet the requirements of different research or application scenarios. At the same time, the balance of the induction pad can be adjusted by increasing or decreasing the number of gaskets to make the induction pad in a horizontal state, which is beneficial to the accuracy of the measurement results. Therefore, the problems of stable installation and fixation of the gait tracking detector, adaptation to different measurement planes, and quick installation and disassembly can be solved.

[0024] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 ,An embodiment provided by the present invention: a high-precision induction pad type animal gait tracking detector, including an induction pad 1. A sensor module is embedded in the bottom of the induction pad 1. A support module is connected to the bottom of the induction pad 1. A waterproof rubber housing 2 is connected to the outer surfaces of the induction pad 1, the sensor module and the support module. The sensor module is used to measure the physical changes of the animal's foot during walking and convert them into electrical signals. The support module is used to provide stable support for the induction pad 1 and the sensor module. The waterproof rubber housing 2 is used to protect the induction pad 1, the sensor module and the support module; The sensor module includes a pressure sensor, a displacement sensor, and a horizontal sensor evenly embedded in the bottom of the induction pad 1, and an acceleration sensor embedded at the bottom edge and the center of the induction pad 1. The pressure sensor is used to measure the pressure generated by the animal's foot during walking. The displacement sensor is used to measure the displacement of the animal's foot relative to the induction pad 1 during walking. The horizontal sensor is used to measure the tilt angle of the induction pad 1 during the animal's walking. The acceleration sensor is used to measure the acceleration of the induction pad 1 when the animal is walking.

[0025] Furthermore, by measuring the pressure distribution and changes exerted by the animal's foot on the sensing pad 1, the pressure sensor can analyze the animal's weight, the pressure peak in the gait cycle, and the information on the movement trajectory of the pressure center, which is of great significance for evaluating the animal's motor ability, gait stability, and potential health problems. The displacement sensor records the displacement of the animal's foot relative to the sensing pad 1 during walking, which helps to analyze the step length, step frequency, and gait fluency, and is very valuable for studying the animal's movement pattern, speed control, and environmental adaptability. The level sensor monitors the tilt angle of the sensing pad 1 during the animal's walking, which helps to correct the influence of the tilt caused by uneven ground or the animal's own movement on the gait data, and improve the accuracy and reliability of the data. The acceleration sensors are distributed at the bottom edge and the center of the sensing pad 1, and can capture the acceleration changes of the sensing pad 1 and the animal on it during walking, which is crucial for analyzing the animal's dynamic stability, gait pattern changes, and possible movement disorders.

[0026] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 In an embodiment provided by the present invention: a high-precision sensing pad type animal gait tracking detector, the output ends of the pressure sensor, the displacement sensor, the level sensor, and the acceleration sensor are connected to a signal amplification and conversion circuit, and the signal amplification and conversion circuit is used for amplifying, converting, filtering, and denoising the detection signal. The output end of the signal amplification and conversion circuit is connected to a circuit board, and the circuit board is used for receiving the signal from the signal amplification and conversion circuit and performing processing and analysis. The output end of the circuit board is connected to a controller, and the controller is used for receiving the data from the circuit board and performing data processing, analysis, and control decision-making.

[0027] Furthermore, since the signals output by the sensor module are often very weak and may contain noise, it is necessary to amplify them to a suitable level for processing through a signal amplification circuit. At the same time, the signal conversion circuit is responsible for converting the analog signals output by the sensor module into digital signals for digital processing. In addition, the filtering and denoising circuit is used to remove the high-frequency noise and interference in the signal and improve the signal-to-noise ratio of the signal. The circuit board is the core processing unit of the animal gait tracking detector. It receives digital signals from the signal amplification and conversion circuit and performs further processing and analysis. The circuit board includes high-performance computing units such as a microprocessor, a digital signal processor, and a field-programmable gate array, which are used to execute complex algorithms and data processing tasks, and then perform filtering, smoothing, and feature extraction operations on the received data to extract gait feature parameters, including but not limited to step length, step frequency, gait cycle, and pressure distribution. At the same time, the circuit board may also have real-time display and storage functions for researchers to view and analyze data at any time; The controller receives data from the circuit board and performs data processing, analysis, and control decisions according to preset algorithms and rules. The controller is also responsible for communicating with other animal gait tracking detectors, transmitting gait data in real time to a computer and a cloud server for further analysis and storage. Based on the processed data, the controller makes a series of control decisions, including adjusting detection parameters, triggering alarms, and starting other relevant animal gait tracking detectors. In the gait tracking detector, these control decisions are used to optimize the detection effect, improve data accuracy, and achieve automated monitoring.

[0028] Please refer to Figure 4 As an embodiment provided by the present invention: a high-precision induction pad type animal gait tracking detector, the support module includes an elastic foam skeleton layer 3 connected to the bottom of the induction pad 1, a silica gel skeleton layer 4 is connected to the bottom of the elastic foam skeleton layer 3, an ABS anti-corrosion skeleton layer 5 is connected to the bottom of the silica gel skeleton layer 4, and the signal amplification and conversion circuit and the circuit board are embedded in the top of the ABS anti-corrosion skeleton layer 5, and an aluminum alloy skeleton layer 6 is connected to the bottom of the ABS anti-corrosion skeleton layer 5.

[0029] Furthermore, the elastic foam skeleton layer 3 serves as the bottom support of the induction pad 1. The elastic foam skeleton layer 3 provides good buffering and shock absorption effects, which helps to reduce the impact on the sensor module generated when the animal walks, thereby improving the accuracy of gait data. At the same time, the elastic foam skeleton layer 3 also has a certain resilience and can maintain the shape and stability of the induction pad 1; The silica gel skeleton layer 4 is located below the elastic foam skeleton layer 3, further enhancing the stability and durability of the animal gait tracking detector. The silica gel skeleton layer 4 has good weather resistance, wear resistance, and anti-aging performance, and can maintain stable performance under various environmental conditions. In addition, the silica gel skeleton layer 4 also has a certain sealing property, which helps to protect the internal circuit from the influence of the external environment; The ABS anti-corrosion skeleton layer 5 is a key part of the support module. It not only provides a strong support structure but also has excellent anti-corrosion performance. The ABS anti-corrosion skeleton layer 5 has good mechanical strength and corrosion resistance, and can resist the erosion of chemical substances and physical impacts. The signal amplification and conversion circuit and the circuit board are embedded on the top of the ABS anti-corrosion skeleton layer 5, and are effectively protected and fixed, ensuring the stable operation of the circuit and the accurate transmission of data; The aluminum alloy skeleton layer 6 is located at the bottom of the ABS anti-corrosion skeleton layer 5 and is the bottom layer of the entire support module. The aluminum alloy skeleton layer 6 has the characteristics of light weight and high strength, can bear a large load and maintain the stability of the animal gait tracking detector. In addition, the aluminum alloy skeleton layer 6 also has good thermal conductivity and corrosion resistance, which helps to dissipate heat and prevent the animal gait tracking detector from rusting; In summary, through the combination of multi-layer structures, the support module realizes the all-round protection and support of the animal gait tracking detector. From the shock absorption and buffering of the elastic foam, to the weather resistance sealing of the silicone, to the anti-corrosion support of the ABS and the stable load-bearing of the aluminum alloy, each layer plays an indispensable role, not only improving the stability and durability of the animal gait tracking detector, but also ensuring the efficiency and accuracy of signal processing, providing reliable technical support for animal gait tracking research.

[0030] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 In an embodiment provided by the present invention: a high-precision inductive pad type animal gait tracking detector, heat dissipation through holes are provided on the sides of the ABS anti-corrosion skeleton layer 5 and the waterproof rubber housing 2. A dust-proof grille and a dust-proof net are arranged inside the heat dissipation through holes, and the dust-proof grille is located inside the dust-proof net, and the density of the dust-proof grille is greater than that of the dust-proof net.

[0031] A waterproof breathable membrane is provided on the side of the waterproof rubber housing 2, and the waterproof breathable membrane is located outside the heat dissipation through hole.

[0032] A waterproof coating is applied on the surface of the waterproof rubber housing 2, and evenly arranged suction cups and stripe anti-slip pads are provided at the bottom of the waterproof rubber housing 2.

[0033] Furthermore, the heat dissipation through holes provided on the sides of the ABS anti-corrosion skeleton layer 5 and the waterproof rubber shell 2 provide an effective heat dissipation channel for heat-generating components such as the circuit board and signal amplification and conversion circuit inside the animal gait tracking detector. The dust-proof grille and dust-proof net provided inside the heat dissipation through holes effectively prevent dust and sundries from entering the inside of the animal gait tracking detector, ensuring the cleanliness and operation stability of the animal gait tracking detector. The density of the dust-proof grille is greater than that of the dust-proof net, which can more effectively block large-particle dust while allowing air circulation, achieving the dual effects of heat dissipation and dust prevention; The waterproof breathable film provided on the side of the waterproof rubber shell 2 is located outside the heat dissipation through hole, which not only ensures the waterproof performance of the animal gait tracking detector but also allows air circulation, avoiding the condensation problem caused by excessive humidity inside the animal gait tracking detector, enabling the animal gait tracking detector to work normally in humid or rainy environments. The surface of the waterproof rubber shell 2 is coated with a waterproof coating, which further enhances the waterproof performance of the animal gait tracking detector. The waterproof coating can effectively block the penetration of moisture and protect the internal circuit and components from damage.

[0034] The bottom of the waterproof rubber shell 2 is provided with evenly arranged suction cups and striped anti-slip pads. The suction cups can firmly adsorb on the ground or other planes, preventing the animal gait tracking detector from sliding or shifting during the animal's walking process. The striped anti-slip pads increase the friction between the animal gait tracking detector and the contact surface, further improving the stability of the animal gait tracking detector, ensuring the stable operation of the animal gait tracking detector in complex environments, and improving the accuracy and reliability of gait tracking.

[0035] In summary, through the ingenious heat dissipation, waterproof and stability designs, the high-precision induction pad type animal gait tracking detector not only ensures the normal operation of the animal gait tracking detector in harsh environments but also improves the accuracy and reliability of gait tracking, making the animal gait tracking detector have broad application prospects in the research fields of animal ethology, ecology, veterinary medicine, etc.

The bottom and outside of the gasket 9 are connected with a magnetic attraction plate two 10. The bottom and outside of the magnetic attraction plate two 10 are connected with an L-shaped fixing block two 11. The outside of the L-shaped fixing block two 11 is connected with an expansion board 12.

[0037] The fixing block 1-7, the magnetic attraction plate 1-8, the gasket 9, the magnetic attraction plate 2-10, the L-shaped fixing block 2-11 and the extension plate 12 are internally connected through bolts, and the bolts are used to fix the induction pad 1 on the measurement plane.

[0038] Further, the fixing block 1-7 connected to the outer side of the waterproof coating serves as the starting point for fixation. The magnetic attraction plate 1-8 connected to its bottom and side provides preliminary adsorption force. The addition of the gasket 9 not only increases the fixation stability but also plays a certain buffering role to prevent damage to the measurement plane caused by excessive magnetic attraction force. The magnetic attraction plate 2-10 at the bottom of the gasket 9 attracts the magnetic attraction plate 1-8, further enhancing the adsorption force and ensuring that the animal gait tracking detector will not shift during the animal's walking process; The L-shaped fixing block 2-11 makes the fixation more firm and flexible. It can pass through the fixing block 1-7, the magnetic attraction plate 1-8, the gasket 9, the magnetic attraction plate 2-10 and itself through bolts, and finally firmly fix the induction pad 1 on the measurement plane. This mechanical fixation method is not limited by the material of the measurement plane and is applicable to various environments. The extension plate 12 connected to the outer side of the L-shaped fixing block 2-11 provides the possibility for the expansion of the animal gait tracking detector, thereby enhancing the functionality and flexibility of the animal gait tracking detector. Combining the advantages of magnetic attraction fixation and mechanical fixation, it not only ensures the rapid stability of the animal gait tracking detector during the initial placement but also ensures the reliability of long-term use through bolt connection. At the same time, it is not limited by the material of the measurement plane. Whether it is a metal, non-metal or special material ground, it can be firmly fixed by adjusting the fixation method, fully considering the actual use requirements. It not only ensures the stability of the animal gait tracking detector but also improves its adaptability and expandability, providing more reliable and flexible technical support for animal gait tracking research.

[0039] Further, the usage method of the animal gait tracking detector is as follows: S1. Fix the animal gait tracking detector; S2. Calibrate the animal gait tracking detector through the controller; S3. Guide the animal to be detected onto the induction pad 1, and the sensor module starts to work; S4. The signal amplification and conversion circuit, the circuit board and the controller perform data collection, processing, result analysis and evaluation.

[0040] Further, in S2, the following steps are also included: S21. Calibrate the pressure sensor, displacement sensor, horizontal sensor and acceleration sensor, including placing an object with a known weight on the induction pad 1 to calibrate the pressure sensor, moving the object to calibrate the displacement sensor and acceleration sensor, and tilting the induction pad 1 to calibrate the horizontal sensor; In S3, the following steps are also included: S31. Induce the animal to approach the sensing pad 1 and guide it onto the sensing pad 1, ensuring that the animal can step on the sensing pad 1 naturally during walking; S32. When the animal starts walking on the sensing pad 1, the sensor module will automatically start working to measure and record the physical changes of the animal's foot; S33. Observe the real-time data on the controller and record the gait characteristics of the animal.

[0041] Working principle: First, fix the animal gait tracking detector on the measurement plane to ensure the stability of the device without shaking. Calibrate the sensor module through the controller, including the calibration of the pressure sensor, displacement sensor, horizontal sensor, and acceleration sensor, to ensure the accuracy of the measurement data; Then, guide the animal to be detected onto the sensing pad 1 and ensure that the animal can step on the sensing pad 1 naturally during walking.

The signal amplification and conversion circuit, circuit board, and controller will collect, process, analyze, and evaluate the data; When the animal's foot steps on the sensing pad 1, the pressure sensor will measure and record the pressure changes generated by the foot. The pressure data reflects the plantar pressure distribution and force changes during the animal's walking. The displacement sensor is used to measure the displacement of the animal's foot relative to the sensing pad 1 during walking. By recording the movement trajectory of the foot, parameters such as the animal's gait pattern and step length can be analyzed. The horizontal sensor is used to monitor the tilt angle of the sensing pad 1 during the animal's walking, which helps to correct the errors caused by uneven ground or device tilt and ensure the accuracy of the measurement data. The acceleration sensor is embedded at the bottom edge and center of the sensing pad 1 to measure the acceleration changes of the sensing pad 1 during the animal's walking. These data can reflect the walking speed and acceleration characteristics of the animal; The controller receives the data from the circuit board, processes, analyzes, and makes control decisions. It performs real-time analysis on the gait data according to the preset algorithms and models, evaluates the gait characteristics, motor ability, and behavior state of the animal. After the analysis is completed, the controller will output the results to the display screen or storage device. Researchers can understand the gait characteristics and behavior patterns of the animal by observing the real-time data on the display screen or referring to the historical data in the storage device.
