Description

Technical Field

[0001] This application relates to the technical field of pet body fat detection, and particularly relates to a pet body fat rate measurement system. Background Art

[0002] The BCS (Body Condition Scoring) method is used to scientifically evaluate the obesity status of pets in order to formulate a reasonable health management plan. The existing BCS scoring method is carried out by observing the overall contour of the pet and touching to evaluate the fat coverage of the ribs, spine and pelvis. In the above method, visual inspection and palpation have high professional requirements for veterinarians, require a lot of experience, and are subjective judgments given manually, with large errors.

[0003] With the development of technology, bioelectrical impedance analysis (BIA) has been applied to pet body fat analysis. However, the bioelectrical impedance value is affected by various factors and there are individual differences, so the accuracy of the evaluation results of pet obesity status is relatively low. For example, changes in body water (such as dehydration or drinking), changes in body temperature and room temperature, different body types, ages and genders, etc.

[0004] Therefore, Chinese invention patent CN115153492A discloses a modular intelligent body fat scale with a pet body shape detection function. Through a matrix grid electrode, it can judge the body length of a pet according to the position where the pet's paw touches, and uses machine vision recognition to replace manual BCS scoring of pet body fat, and comprehensively gives pet body fat data. However, the measurement accuracy of the matrix grid electrode in this solution is not high, and the accuracy of BCS scoring by machine vision is also relatively low, resulting in relatively low accuracy of the evaluation results of pet obesity status.

Specific implementation mode

[0021] Performing body fat detection on pets and evaluating the obesity status of pets helps to comprehensively understand the health status of pets, prevent diseases, and optimize breeding and sports performance. For example, it helps to determine whether a pet is overweight or obese and prevent related diseases; early detect metabolic problems such as diabetes and fatty liver, etc., and accordingly formulate personalized diet and exercise plans for pets.

[0022] This application provides a pet body fat rate measurement system. A pet body fat rate calculation model is constructed by using multiple groups of body shape data, impedance data, and body fat rate data of different breeds of pets. The three-dimensional automatic measurement device and detection electrodes on the body fat scale are used to automatically measure the body shape data and impedance data of the pet, and the body fat rate of the current pet is calculated by combining the characteristic data of the pet and the pet body fat rate calculation model, which is convenient to use and has high accuracy.

[0023] Next, the technical solutions of the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the following described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0024] In order to make a clearer explanation and illustration of the technical solutions and implementation manners of the present invention, the following introduces several preferred specific embodiments for implementing the technical solutions of the present invention.

[0025] It should be noted that the orientation words such as "inside, outside", "front, back", and "left, right" in this article are expressed based on the product usage state as the reference object. Obviously, the use of the corresponding orientation words does not constitute a limitation to the protection scope of this solution.

[0026] Such as Figure 1As shown in the figure, a pet body fat rate measurement system provided by the present invention includes a body fat scale 100, a host 200, and a body fat rate calculation module. The body fat rate calculation module includes a pet body fat rate calculation model, which is obtained by constructing with multiple groups of body shape data, impedance data, and body fat rate data of different breeds of pets. When a pet stands on the body fat scale 100, the current pet's body shape data and impedance data can be automatically measured, and then the pet's body fat rate can be automatically calculated using the pet body fat rate calculation model. The host 200 includes an input device and a display screen. The input device is used to input the characteristic data of the pet, and the display screen is used to display the measurement result of the pet body fat rate.

[0027] Among them, the pet's body shape data includes the pet's body length, body width, shoulder height, and weight.

[0028] The pet's characteristic data includes pet ID, breed, and age, which can be input through the input device.

[0029] The pet's impedance data can be obtained by measuring with electrodes provided on the body fat scale 100.

[0030] Specifically, the calculation formula of the pet body fat rate calculation model R is as follows: R = a1 + a2 × shoulder height + a3 × age + a4 × impedance + a5 × body width + a6 × BMI; Among them, a1 is a constant, and a2, a3, a4, a5, and a6 are linear fitting parameters; BMI = weight / body length 2 。

[0031] The unit of shoulder height and body width is cm, the unit of age is years, the unit of impedance is Ω, the unit of weight is kg, and the unit of body length is m.

[0032] The larger the amount of data collected, the more accurate the parameter values of the constant a1 and the fitting parameters a2, a3, a4, a5, a6, and the higher the accuracy rate of the pet body fat rate calculation model R.

[0033] Using multiple groups of experimental data of pet dogs, the calculation formula of the body fat rate calculation model R of pet dogs is obtained as follows: R = -18.087 - 0.267 × shoulder height + 0.712 × age + 0.008 × impedance + 1.235 × body width + 0.172 × BMI.

[0034] Therefore, according to the pet body fat rate calculation model, using the measured body shape data and impedance data of the current breed of pet, the body fat rate of the current breed of pet can be calculated, and the measurement result is fast, accurate, and easy to use.

[0035] In the present invention, the body fat percentage calculation module can be set on the body fat scale 100, or on the host 200, or in the cloud. The specific setting method can be set according to the usage scenario. For example, the body fat percentage calculation module can be set on the body fat scale 100. In this way, the body shape data and bioelectrical impedance data of the pet can be measured by the body fat scale 100, and the body fat percentage of the pet can be directly calculated and then transmitted to the host 200 for display. No software or application needs to be installed on the host 200, which is suitable for use in any occasion and is convenient to use. Another way is to set the body fat percentage calculation module on the host 200. The body fat scale 100 measures the body shape data and bioelectrical impedance data of the pet and transmits them to the host 200. The host 200 calculates the body fat percentage of the pet and displays it. Since the body fat percentage calculation module is implemented by an APP, it can be installed on any host, effectively reducing the cost of the body fat percentage, and it is more convenient to update and upgrade the body fat percentage calculation module.

[0036] As Figure 2 shown, the body fat scale 100 includes a base 10, a pet three-dimensional measurement device, bioelectrical impedance measurement electrodes, and a weight measurement device provided on the base 10. The pet three-dimensional measurement device is used to measure the body width, body length, and shoulder height of the pet. The bioelectrical impedance measurement electrodes are used to measure the bioelectrical impedance of the pet. The weight measurement device is used to measure the weight of the pet.

[0037] The pet three-dimensional measurement device includes two body width measurement rulers 21, two body length measurement rulers 22, and one shoulder height measurement ruler 23. The body width measurement rulers 21, body length measurement rulers 22, and shoulder height measurement rulers 23 are made of soft materials to ensure the safety of the pet during measurement.

[0038] Specifically, longitudinal chutes 11 and transverse chutes 12 are perpendicularly provided on the top surface of the base 10, and the longitudinal chutes 11 and transverse chutes 12 intersect at the center of the base 10. Four metal plates are provided on the top surface of the base 10, and the four metal plates are arranged in a cross shape with respect to the longitudinal chutes and transverse chutes. The metal plates form the detection electrodes for bioelectrical impedance measurement. When the pet stands on the metal plates, the bioelectrical impedance of the pet can be measured. In a preferred embodiment, the left and right or front and rear two metal plates are short-circuited to form two detection electrodes (positive and negative electrodes), which not only simplifies the solution but also improves the accuracy of the measurement result.

[0039] The two body width measurement rulers 21 are respectively arranged in the longitudinal chutes 11. A longitudinal slider is provided in the longitudinal chutes 11. The longitudinal slider and the longitudinal chutes 11 form a longitudinal grid displacement measurement device. The lower end of the body width measurement ruler 21 is rotatably provided on the longitudinal slider, and the longitudinal slider can move along the length direction of the longitudinal chutes 11 to measure the body width of the pet.

[0040] Two body length measuring rulers 22 are respectively arranged in the transverse sliding grooves 12. A transverse slider is arranged in the transverse sliding grooves 12. The transverse slider and the transverse sliding grooves 12 form a longitudinal capacitance displacement measuring device. The lower end of the body length measuring ruler 22 is rotatably arranged on the transverse slider. The transverse slider can move along the length direction of the transverse sliding grooves 12 to measure the body length of the pet.

[0041] When in use, the body width measuring ruler 21 and the body length measuring ruler 22 can be rotated upward to be perpendicular to the top surface of the base 10. At the same time, they can move along the longitudinal sliding groove 11 and the transverse sliding groove 12 respectively and lean against the left and right sides and the front and back sides of the pet, so as to measure the body width and body length of the pet.

[0042] When not in use, the body width measuring ruler 21 and the body length measuring ruler 22 can be rotated downward to the horizontal state for hiding, that is, hidden on the base, reducing the occupied space and facilitating collection and movement.

[0043] The shoulder height measuring ruler 23 includes a vertical rod 231 and a horizontal rod 232 arranged on the vertical rod 231. The horizontal rod 232 is slidably connected with the vertical sliding groove on the inner side surface of the vertical rod 231 through a vertical slider. The vertical slider and the vertical sliding groove form a vertical capacitance displacement measuring device. Thus, the horizontal rod 232 can be moved up and down along the vertical rod 231 and lean against the shoulder of the pet to measure the shoulder height of the pet.

[0044] In the present invention, the horizontal rod 232 adopts a multi-rod telescopic structure. A vertical groove is arranged in the vertical sliding groove. The width of the vertical groove is greater than the thickness of the horizontal rod 232. One end of the horizontal rod 232 is rotatably arranged on the vertical slider. Thus, the horizontal rod 232 can be rotated downward to the vertical state for hiding, that is, hidden in the vertical sliding groove.

[0045] In one embodiment, a side groove 13 is arranged along the length direction on the side surface of the base 10. The side groove 13 is adapted to the vertical rod 231. The lower end of the vertical rod 231 is rotatably arranged at one end of the side groove 13. The vertical rod 231 can be rotatably arranged in two states of vertical and horizontal. When rotated to the vertical state, it is used for shoulder height measurement. When rotated to the horizontal position, the vertical rod 231 is opposite to the side groove 13. Pushing the vertical rod 231 inward, the vertical rod 231 can be hidden in the side groove 13, thus facilitating storage and transportation.

[0046] The combination relationship between the body width measuring ruler 21 and the longitudinal slider is as Figure 3 shown. Measuring ruler rotating shafts are respectively arranged on both sides of the lower end of the body width measuring ruler 21. The longitudinal slider includes a connecting seat 31 and a slider body 32 arranged on the bottom surface of the connecting seat 31. The slider body 32 is slidably arranged in the longitudinal sliding groove 11. A U-shaped notch is arranged on the connecting seat 31. The measuring ruler rotating shaft is rotatably arranged in the U-shaped notch.

[0047] The hidden structure of the vertical rod 231 can adopt the following structure: As Figure 4 shown, one end of the side groove 13 on the base 10 is provided with a shaft hole, and the lower end of the vertical rod 231 is provided with a vertical rod rotating shaft 233. The vertical rod rotating shaft 233 is adapted to the shaft hole and is inserted into the shaft hole for rotational cooperation.

[0048] A strip-shaped groove 14 is provided on the bottom surface of the base 10. The strip-shaped groove 14 is arranged along the axial direction of the rotating shaft at the lower end of the vertical rod 231. A limiting piece 234 is provided at the end of the vertical rod rotating shaft 233. The limiting piece 234 slides in the strip-shaped groove 14 to limit the position where the vertical rod 231 is pulled out and retracted.

[0049] In the solution of this application, when not in use, the body width measuring ruler 21, the body length measuring ruler 22 and the shoulder height measuring ruler 23 can all be rotated downward and hidden on the base 10, so as to facilitate storage and transportation, as Figure 5 shown.

[0050] A signal transmission unit is provided inside the base 10 for transmitting the detection data to the processing host 200. The signal transmission unit can be connected to the host 200 in a wired or wireless manner.

[0051] In Figure 6 a shown usage scenario, the body fat scale 100 is connected to the host 200 in a wireless manner. The body fat rate calculation module is integrated in the pet body fat measurement app. The pet body fat measurement app is installed on a tablet computer or a smart TV. After receiving the measurement data of the body fat scale 100, the current pet body fat rate is calculated using the body fat rate calculation module and displayed on the display interface.

[0052] Each detection result data and result can be saved on the server. The user can log in to the server through the user name and password and query the detection results and historical records of the pet through the pet ID.

[0053] An RFID reader-writer can be set on the body fat scale 100 or the host 200 to read the pet tag through the RFID reader-writer to identify and obtain the pet's characteristic data, or use the biochip technology to identify and read.

[0054] When performing pet bioelectrical impedance measurement, the standard requires that the four feet of the pet stand on the four metal plates on the base respectively. However, in actual applications, the pet will keep moving or even lie on the base, resulting in inaccurate measurement results or unable to measure the pet's bioelectrical impedance. To avoid this problem, the solution of this application sets a detachable and dismountable abdominal support device 40 on the base 10 to limit the movement or lying down of the pet.

[0055] As Figure 7 、 Figure 8 、 Figure 9As shown, the abdominal support device 40 includes an abdominal support 41 and a support rod 42, and the abdominal support 41 is fixed to the upper end of the support rod 42.

[0056] A jack 15 is provided at the center of the base 10. A plurality of pressure rods 16 are provided along the circumferential direction in the jack 15. A microswitch is provided in the base 10 corresponding to each pressure rod. The pressure rod 16 is slidably arranged up and down and opposite to the pressing end of the microswitch, and the corresponding microswitch can be opened or closed by moving the pressure rod 16 up and down.

[0057] A sleeve 17 is fixedly inserted in the jack 15. An axially arranged strip-shaped convex rib 171 is provided on the inner wall of the sleeve 17. A limiting groove 421 is provided on the lower end face of the tube wall of the support rod 42. The limiting groove 421 is adapted to the strip-shaped convex rib 171, and the support rod 42 is inserted into the sleeve 17.

[0058] In this application, the support rod 42 adopts a circular tube structure and is adapted to the inner diameter of the sleeve 17. A plurality of notches 422 are provided along the circumferential direction on the lower end face of the tube wall of the support rod 42. The positions of the respective notches correspond to the positions of the pressure rods 16 respectively, and each notch has a first depth and a second depth. The first depth is greater than the height of the pressure rod 16, and the second depth is less than the height of the pressure rod 16, and is used to press down and close the corresponding microswitch.

[0059] For abdominal support devices of different models, the positions and numbers of the notches with the second depth on the support rod 42 are different. When the abdominal support devices of different models are inserted and positioned with the limiting groove 421 and the strip-shaped convex rib 171, different notches press different pressure rods, thereby closing different microswitches. Thus, according to the combination of the closing states of different microswitches, the corresponding model of the abdominal support device can be known, and the weights of the abdominal support devices of different models are input into the body fat percentage calculation module in advance, so that when measuring the weight of the pet, the peeling process can be carried out for different models of abdominal support devices to obtain the actual weight of the pet.

[0060] Figure 10 It is a schematic diagram of the application of the abdominal support device.

[0061] Next, the identification method of the abdominal support device will be described in detail through an embodiment.

[0062] In this embodiment, three microswitches A, B, and C are provided in the base 10. The depths of the notches on the support rod 42 of the first model abdominal support device corresponding to the two microswitches A and B are less than the height of the pressure rod 16. When the first model abdominal support device is inserted, the microswitches A and B are closed, and the microswitch C is disconnected, generating a signal 110.

[0063] On the support rod 42 of the second model abdominal support device, the notches corresponding to the two microswitches A and C have a depth less than the height of the pressure rod 16. When the second model abdominal support device is inserted, the microswitches A and C are closed, and the microswitch B is opened, generating the signal 101.

[0064] On the support rod 42 of the third model abdominal support device, the notches corresponding to the two microswitches B and C have a depth less than the height of the pressure rod 16. When the third model abdominal support device is inserted, the microswitches B and C are closed, and the microswitch A is opened, generating the signal 011.

[0065] Thus, when the three different models of abdominal support devices are inserted, the states of the respective microswitches and the corresponding generated abdominal support signals are as follows: Abdominal support device model Microswitch A Microswitch B Microswitch C Abdominal support signal First Closed Closed Open 110 Second Closed Open Closed 101 Third Open Closed Closed 011 The corresponding abdominal support device model can be obtained according to the received abdominal support signal (110, 101 or 011), and then the weight of the currently used abdominal support device can be obtained, so as to remove the weight of the abdominal support device when measuring the weight and obtain the actual weight of the pet.

[0066] The above embodiments are only exemplary descriptions. Three, five or more microswitches can be set according to actual needs to adapt to more models of abdominal support devices.

[0067] In addition, the support rod can adopt a pull-out lift rod to adapt to pets of different body heights.

[0068] The abdominal support device is made of insulating material to ensure the accuracy of the bioelectrical impedance data during measurement.

[0069] Based on the description of the above specific embodiments, the pet body fat rate measurement system provided by the invention has the following advantages compared with the prior art: A pet body fat rate calculation model is constructed by using multiple sets of body shape data, impedance data and body fat rate data of different breeds of pets. By obtaining the body shape data and impedance data of the current pet and automatically calculating the body fat rate of the current pet by using the pet body fat rate calculation model, it is fast, efficient, highly accurate and easy to use.

[0070] Second, a pet three-dimensional measurement device, a bioelectrical impedance measurement device and a weight measurement device are provided on the body fat scale. The body shape data and impedance data of the current pet are automatically measured through two body width measurement scales, two body length measurement scales and a shoulder height measurement scale arranged in a relatively sliding manner. The measurement speed is fast and it is easy to use.

[0071] Third, when not in use, the body width measurement scale and the body length measurement scale in the pet three-dimensional measurement device can be rotated downward and hidden in the longitudinal and transverse chutes on the top surface of the base, which is convenient for storage and movement.

[0072] Fourth, there is a certain frictional force between the longitudinal slider, the transverse slider, and the vertical slider and the groove walls of the corresponding chutes, and they can stay at any position, which is convenient for measurement.

[0073] Finally, it should also be noted that the term "including", "comprising" or any other variant thereof used in this text is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent in such process, method, article or device. Without further limitation, an element defined by the statement "including one..." does not exclude the presence of additional identical elements in the process, method, article or device including the said element.

[0074] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone should know that structural changes made under the inspiration of the present invention, as long as they have the same or similar technical solutions as the present invention, all fall within the protection scope of the present invention.
