Description

Technical Field

[0001] This invention relates to the field of livestock equipment technology, and more specifically, to an animal chewing self-generating power system and a sensing tether. Background Technology

[0002] Chewing occurs during the processes of eating and rumination in animals. Eating, rumination, and drinking all involve a large number of chewing actions. Chewing can be broken down into these behaviors, which can reflect more comprehensive health and breeding information. Monitoring chewing behavior has become one of the keys to intelligent livestock farming.

[0003] Currently, livestock are raised in two modes: free-range and pen-raising. China's livestock farming is developing towards large-scale operations. The question is how to utilize the mechanical energy of animals' chewing actions to convert it into electrical energy to power smart wearable devices for animals, so as to achieve full-process monitoring of animals' physiological health throughout their entire life cycle. Summary of the Invention

[0004] The purpose of this invention is to provide an animal chewing self-generating power system and a sensing cage, so as to utilize the mechanical energy of the animal's chewing action to convert it into electrical energy, thereby powering the animal's smart wearable device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An animal chewing self-generating power system includes a chewing power generation shell, a chewing generator, a fixed pulley block, a movable pulley block, a first chewing power generation rope, and a second chewing power generation rope. The chewing power generation housing is provided with a rotatable chewing main shaft; the rotating shaft of the chewing generator is connected to the chewing main shaft, and the rotating shaft of the chewing generator is configured to rotate with the chewing main shaft; a main shaft pulley is sleeved on the chewing main shaft, and a first one-way bearing is assembled between the main shaft pulley and the chewing main shaft; The fixed pulley assembly is fixedly connected inside the chewing power generation housing, and the movable pulley assembly is slidably connected inside the chewing power generation housing; The first end of the first chewing power generation pull rope and the first end of the second chewing power generation pull rope extend out of the chewing power generation housing respectively; the tail ends of the first chewing power generation pull rope and the tail ends of the second chewing power generation pull rope respectively pass around the main shaft pulley, and then alternately wind around the pulleys of the fixed pulley group and the movable pulley group, and are fixedly connected to the chewing power generation housing. When the first chewing power generation rope and the second chewing power generation rope are pulled, the main shaft pulley rotates around the first direction, the first one-way bearing is locked, the chewing main shaft rotates synchronously with the main shaft pulley, and the rotating shaft of the chewing generator rotates with the chewing main shaft to generate electricity.

[0006] In one possible implementation, the tail ends of the first chewing power generation cord and the second chewing power generation cord are elastic; the elastic deformation of the first chewing power generation cord and the second chewing power generation cord has a tendency to drive the main shaft pulley to rotate about a second direction, at which time the first one-way bearing is disengaged and the chewing main shaft does not rotate with the main shaft pulley; the second direction is opposite to the first direction.

[0007] In one possible implementation, the animal chewing self-generating system further includes a driving gear and a driven gear; both the driving gear and the driven gear are pivotally connected within the chewing power generation housing. The drive gear is sleeved on the chewing spindle, and a second one-way bearing is assembled between the drive gear and the chewing spindle; When the first chewing power generation cord and the second chewing power generation cord are pulled, the chewing main shaft rotates around the first direction with the main shaft pulley, the second one-way bearing is disengaged, and the drive gear does not rotate with the chewing main shaft; The chewing generator is a generator-motor; when the generator-motor is in motor mode, the generator-motor shaft drives the chewing main shaft to rotate around the second direction, the second one-way bearing is locked, the driving gear rotates with the chewing main shaft, and the driving gear meshes with the driven gear, so that the driven gear drives the housing of the movable pulley group to move, thereby changing the distance between the fixed pulley group and the movable pulley group, and thus changing the length of the first end of the chewing generator pull rope and the first end of the second chewing generator pull rope extending out of the chewing generator housing; the second direction is opposite to the first direction.

[0008] In one possible implementation, the housing of the movable pulley block is provided with a first sliding groove; the driven gear is provided with a guide post that can slide within the first sliding groove; When the driving gear meshes with the driven gear, the guide post abuts against the slide wall of the first slide groove to drive the housing of the movable pulley assembly to move.

[0009] In one possible implementation, a movable block is provided inside the housing of the movable pulley assembly, and a second sliding groove is provided on the movable block; the guide post can slide along the second sliding groove, and at least a portion of the second sliding groove overlaps with a portion of the first sliding groove; The housing of the movable pulley assembly is connected to an elastic element that abuts against the movable block. The elastic element has an elastic deformation that drives the movable block away from the elastic element. The driving gear and the elastic element are located at both ends of the driven gear; When the driven gear drives the housing of the movable pulley assembly to move, the elastic element can be compressed, thereby causing the movable block to move within the housing of the movable pulley assembly, so that the guide post reaches and passes through the far-travel limit position.

[0010] In one possible implementation, the generator motor uses a first driving force to adjust the exposed length of the chewing power generating cord, the first driving force being less than the elastic deformation restoring force of the elastic element, so as to fix the position of the movable block relative to the housing of the movable pulley assembly; wherein, the chewing power generating cord includes the first chewing power generating cord and the second chewing power generating cord; The generator motor has a second driving force greater than the elastic deformation restoring force of the elastic element, and the movable block is configured to compress the elastic element under the drive of the second driving force, so that the movable block moves within the housing of the movable pulley assembly, thereby causing the guide post to reach and pass through the far-travel limit position.

[0011] In one possible implementation, the cross-sectional area of ​​the movable block on the surface perpendicular to the axial direction of the driven gear is larger than the cross-sectional area of ​​the first groove.

[0012] In one possible implementation, the first chewing power generation cord and the second chewing power generation cord extend from two opposite surfaces of the chewing power generation housing, respectively; The first chewing power generation rope and the second chewing power generation rope pass around the main shaft pulley from opposite directions.

[0013] In one possible implementation, the animal chewing self-generating system further includes a chewing tension sensor; one end of the chewing tension sensor is connected to the tail end of the first chewing power generating rope and the tail end of the second chewing power generating rope, respectively, and the other end is fixedly connected to the chewing power generating housing.

[0014] A sensing tether includes the aforementioned animal chewing self-generating system, and also includes a cord for attaching to the outer contour of the animal's mouth. The rope has a break; the first end of the first chewing power generation rope and the first end of the second chewing power generation rope of the animal chewing self-generating system are respectively connected to the two ends of the break.

[0015] The main advantages of the present invention, achieved by adopting the above technical solution, are as follows: The animal chewing self-generating power system and sensing cage provided by this invention can effectively convert chewing mechanical energy into electrical energy, thereby facilitating the power supply of smart wearable devices for animals. Specifically, when an animal chews and opens its mouth, the ropes fitted around the outer contour of the animal's mouth simultaneously pull the first and second chewing power generating ropes, causing the main shaft pulley to rotate around a first direction. At this time, the first one-way bearing is locked, and the chewing main shaft rotates synchronously with the main shaft pulley. The rotating shaft of the chewing generator rotates with the chewing main shaft to generate electricity.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0022] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0023] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0026] Chewing behavior occurs in animals during feeding and rumination. Although many devices have been proposed to monitor animal chewing behavior and understand their rumination and feeding, these devices still have considerable room for improvement.

[0027] A livestock chewing detection device and intelligent ranch management system (Chinese Patent No. 2018104351645) is disclosed. This livestock chewing detection device uses a pull-wire rotation method to detect the degree of jaw opening and closing in livestock, and its accuracy can reach a high level. However, the structure of the above device is slightly complicated, and it uses solar power for charging. In a confined environment, solar power cannot play a very good role, and the battery still needs to be replaced or recharged regularly.

[0028] A self-generating livestock chewing detection device and method (Chinese Patent No. 2021112731012) is disclosed. This method uses a chain with spacers to drive a piezoelectric element to vibrate at high frequency, generating electricity while detecting the animal's chewing movements. However, the zipper-style design cannot adaptively adjust the length, and manual wearing is time-consuming due to animal resistance, resulting in low efficiency. Furthermore, compared to electromagnetic power generation, piezoelectric power generation is relatively inefficient, only capable of powering ultra-low-power devices. Since current AI algorithms require large amounts of electrical energy, piezoelectric power generation is unsuitable for devices that perceive large amounts of behavioral data and load AI algorithms.

[0029] In summary, the existing technology mainly has the following problems: (1) The current perception of chewing behavior in animals is mostly monitored by sensors to monitor jaw movement. However, different animals and different sizes of the same animal make it difficult to fit the sensor auxiliary rope on the jaw in the same way. For example, it may be too tight or too loose. As the animal grows larger with age, it may become too tight. This inconsistency will result in different initial values, which will increase the difficulty of extracting behavioral features from subsequent data.

[0030] (2) For docile animals, the piezoelectric power generation efficiency is relatively low, and the chain rope vibrates and rubs against the piezoelectric plate, which easily leads to wear and tear. It is only suitable for short-term data acquisition and power supply of low-power equipment, and the length of the muzzle auxiliary rope cannot be dynamically adjusted, which cannot meet the integration of power-consuming algorithms such as AI.

[0031] To ensure that the equipment worn by animals in both free-range and captive-keeping modes can be continuously powered by the animals' own mechanical energy, and to reduce the manual labor involved in changing batteries and wearing bridles, this embodiment provides an animal chewing self-generating power system.

[0032] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0033] This embodiment provides an animal chewing self-generating power system and a sensing tether, which can be used for animals such as cattle, horses, sheep, deer, and dogs.

[0034] See Figures 1-9 As shown, the animal chewing self-generating power system provided in this embodiment includes a chewing power generation housing 310, a chewing generator 340, a fixed pulley group 350, a movable pulley group 360, a first chewing power generation pull rope 370, and a second chewing power generation pull rope 380. The first chewing power generation pull rope 370 and the second chewing power generation pull rope 380 can be connected to a rope 100 used to cover the outer contour of the animal's mouth; for example, the rope 100 is provided with a break; the first end of the first chewing power generation pull rope 370 and the first end of the second chewing power generation pull rope 380 are respectively connected to the two ends of the break, so that the animal chewing self-generating power system and the rope 100 form a ring and are covered on the outer contour of the animal's mouth.

[0035] The chewing generator housing 310 is provided with a rotatable chewing main shaft; the rotating shaft of the chewing generator 340 is connected to the chewing main shaft, and the rotating shaft of the chewing generator 340 is configured to rotate with the chewing main shaft; a main shaft pulley 321 is sleeved on the chewing main shaft, and a first one-way bearing is assembled between the main shaft pulley 321 and the chewing main shaft.

[0036] The fixed pulley assembly 350 is fixedly connected inside the chewing power generation housing 310, and the movable pulley assembly 360 is slidably connected inside the chewing power generation housing 310.

[0037] The first end of the first chewing power generation pull rope 370 and the first end of the second chewing power generation pull rope 380 extend out of the chewing power generation housing 310, respectively. The tail ends of the first chewing power generation pull rope 370 and the second chewing power generation pull rope 380 pass over the main shaft pulley 321, and then alternately wind around the pulleys of the fixed pulley group 350 and the movable pulley group 360, and are fixedly connected to the chewing power generation housing 310. That is, the first ends of the first chewing power generation pull rope 370 and the first ends of the second chewing power generation pull rope 380 are both located outside the chewing power generation housing 310, and the tail ends of the first chewing power generation pull rope 370 and the second chewing power generation pull rope 380 are both located inside the chewing power generation housing 310.

[0038] When the first chewing power generation cord 370 and the second chewing power generation cord 380 are pulled, for example, when the cord 100 pulls both the first chewing power generation cord 370 and the second chewing power generation cord 380 simultaneously, the main shaft pulley 321 rotates around a first direction, the first one-way bearing is locked, the chewing main shaft rotates synchronously with the main shaft pulley 321, and the rotating shaft of the chewing generator 340 generates electricity as the chewing main shaft rotates. For example, when the animal chews and opens its mouth, the cord 100 pulls both the first chewing power generation cord 370 and the second chewing power generation cord 380 simultaneously; when the animal chews and closes its mouth, the first chewing power generation cord 370 and the second chewing power generation cord 380 retract into the chewing power generation housing 310.

[0039] The animal chewing self-generating power system described in this embodiment can effectively convert chewing mechanical energy into electrical energy, thereby facilitating the power supply of animal smart wearable devices. Specifically, when the animal chews and opens its mouth, the rope 100 fitted around the outer contour of the animal's mouth simultaneously pulls the first chewing power generation rope 370 and the second chewing power generation rope 380, causing the main shaft pulley 321 to rotate around a first direction. At this time, the first one-way bearing is locked, the chewing main shaft rotates synchronously with the main shaft pulley 321, and the rotating shaft of the chewing generator 340 generates electricity by rotating with the chewing main shaft.

[0040] In an optional embodiment, the tail ends of the first chewing power generation pull rope 370 and the second chewing power generation pull rope 380 are elastic; the elastic deformation of the first chewing power generation pull rope 370 and the second chewing power generation pull rope 380 has a tendency to drive the main shaft pulley 321 to rotate around the second direction. At this time, the first one-way bearing is disengaged, and the chewing main shaft does not rotate with the main shaft pulley 321. That is, the main shaft pulley 321 rotates freely on the chewing main shaft. The chewing main shaft is fixed relative to the chewing power generation housing 310 or continues to rotate around the first direction under inertia. The rotating shaft of the chewing generator 340 is fixed relative to the chewing power generation housing 310 or continues to rotate around the first direction under inertia. The second direction is opposite to the first direction.

[0041] In this embodiment, when the animal chews and generates electricity, the animal chews with its mouth open, and the chewing main shaft rotates synchronously with the main shaft pulley 321 around the first direction. The rotating shaft of the chewing generator 340 rotates with the chewing main shaft to generate electricity. When the animal chews and closes its mouth, the main shaft pulley 321 rotates around the second direction, and the chewing main shaft does not rotate with the main shaft pulley 321. The chewing main shaft does not rotate or continues to rotate around the first direction under the action of inertia, so that the rotating shaft of the chewing generator 340 does not rotate or continues to generate electricity.

[0042] In this embodiment, the animal chewing self-generating power system 300 can employ a single chewing generator 340 to simultaneously generate electricity and electrically adjust the ropes. For example, by rotating the shaft of the chewing generator 340 forward to generate electricity and reversing it to adjust the exposed lengths of the first chewing power generating rope 370 and the second chewing power generating rope 380, it can adapt to the jaws of different animals and animals of different ages, allowing the animal chewing self-generating power system to be more appropriately worn on the animal. See also Figures 3-9 As shown, in an optional embodiment, the animal chewing self-generating system further includes a drive gear 320 and a driven gear 330; both the drive gear 320 and the driven gear 330 are pivotally connected within the chewing power generation housing 310. The drive gear 320 is sleeved on the chewing spindle, and a second one-way bearing is assembled between the drive gear 320 and the chewing spindle; optionally, the spindle pulley 321, the chewing spindle, the second one-way bearing, the shaft of the chewing generator 340 and the drive gear 320 are coaxially arranged.

[0043] When the first chewing power generation cord 370 and the second chewing power generation cord 380 are pulled, the chewing main shaft rotates around the first direction with the main shaft pulley 321, the second one-way bearing disengages, and the driving gear 320 does not rotate with the chewing main shaft. For example, when the cord 100 pulls the first chewing power generation cord 370 and the second chewing power generation cord 380, that is, when the animal chews and opens its mouth, the main shaft pulley 321 rotates around the first direction, the chewing main shaft rotates around the first direction with the main shaft pulley 321, the second one-way bearing disengages, and the driving gear 320 does not rotate with the chewing main shaft; that is, the chewing main shaft spins freely on the driving gear 320, and the driving gear 320 and the driven gear 330 are fixed relative to the chewing power generation housing 310. By setting the second one-way bearing, the influence of the driving gear 320 and the driven gear 330 on the power generation of the chewing generator 340 can be effectively avoided. In other words, when the chewing generator 340 generates electricity, the driving gear 320 and the driven gear 330 do not rotate.

[0044] The chewing generator 340 is a generator-motor. When the generator-motor is in motor mode, its shaft drives the chewing main shaft to rotate in a second direction. The second one-way bearing is locked, and the driving gear 320 rotates with the chewing main shaft. The driving gear 320 meshes with the driven gear 330, causing the driven gear 330 to drive the housing of the movable pulley block 360 to move, thereby changing the distance between the fixed pulley block 350 and the movable pulley block 360. This, in turn, changes the length of the first chewing generator pull rope 370 and the first chewing generator pull rope 380 extending out of the chewing generator housing 310, thus adjusting the length of the chewing generator pull ropes protruding from the chewing generator housing 310. The second direction is opposite to the first direction. At this time, the first one-way bearing is disengaged, the chewing main shaft does not rotate with the main shaft pulley 321, and the shaft of the chewing generator 340 does not rotate.

[0045] See Figures 5-8 As shown, in an optional embodiment, the housing of the movable pulley assembly 360 is provided with a first groove 361; the driven gear 330 is provided with a guide post 331 that can slide within the first groove 361; when the driving gear 320 meshes with the driven gear 330, the guide post 331 abuts against the groove wall of the first groove 361 to drive the housing of the movable pulley assembly 360 to move. Optionally, the guide post 331 is not provided on the rotation shaft of the driven gear 330. In this embodiment, when the driven gear 330 rotates, the housing of the movable pulley assembly 360 can be driven to move through the guide post 331. Through the first groove 361 and the guide post 331, the force of the driven gear 330 is better transmitted to the housing of the movable pulley assembly 360.

[0046] In this embodiment, when the generator motor is in motor mode, the guide post 331 of the driven gear 330 drives the housing of the movable pulley assembly 360 to move. When it moves to the far end (the end of the movable pulley assembly 360 away from the fixed pulley assembly 350), the housing of the movable pulley assembly 360 is easily jammed. To solve the above problem, see [reference needed]. Figure 8 As shown, in an optional embodiment, a movable block 362 is provided inside the housing of the movable pulley block 360, and a second sliding groove 363 is provided on the movable block 362; the guide post 331 can slide along the second sliding groove 363, and at least part of the second sliding groove 363 overlaps with part of the first sliding groove 361; optionally, the second sliding groove 363 can be located inside the first sliding groove 361.

[0047] The housing of the movable pulley block 360 is connected to an elastic element 364 that abuts against the movable block 362. The elastic element 364 has elastic deformation that drives the movable block 362 away from the elastic element 364.

[0048] The driving gear 320 and the elastic element 364 are located at both ends of the driven gear 330.

[0049] When the driven gear 330 drives the housing of the movable pulley block 360 to move, the elastic member 364 can be compressed, thereby allowing the movable block 362 to move within the housing of the movable pulley block 360, so that the guide post 331 reaches and passes the far stroke limit position. The far stroke limit position is the farthest point of the guide post 331 on the circumferential track of the driven gear 330 away from the driving gear 320, and this position corresponds to the limit position of the movable block 362 moving to the right. By driving the housing of the movable pulley block 360 to move through the driven gear 330, the elastic member 364 is compressed, thereby allowing the movable block 362 to move within the housing of the movable pulley block 360, which enables the guide post 331 to successfully pass the stuck point, facilitates the animal chewing self-power generation system 300 to enter the state of readjusting the length, and enables the unidirectional rotating generator-motor to repeatedly adjust the position of the movable pulley block 360, thereby facilitating achievement of an optimal state.

[0050] In the optional solution of this embodiment, the generator-motor uses a first driving force to adjust the exposed length of the chewing power generation pull rope, and the first driving force is smaller than the elastic deformation restoring force of the elastic member 364, so that the position of the movable block 362 relative to the housing of the movable pulley block 360 is fixed, that is, the movable block 362 moves synchronously with the housing of the movable pulley block 360; wherein the chewing power generation pull rope comprises a first chewing power generation pull rope 370 and a second chewing power generation pull rope 380.

[0051] The generator-motor has a second driving force greater than the elastic deformation restoring force of the elastic member 364, and the movable block 362 is configured to compress the elastic member 364 driven by the second driving force, so that the movable block 362 moves within the housing of the movable pulley block 360, thereby enabling the guide post 331 to reach and pass the far stroke limit position.

[0052] In this embodiment, for example, the first driving force corresponds to a driving voltage duty cycle of 50% of the generator-motor, and the second driving force corresponds to a driving voltage duty cycle of 80% of the generator-motor. Under a larger driving force, the movable block 362 drives the elastic member 364 to be compressed again, so that the movable pulley block 360 remains stationary and the movable block 362 moves. After the guide post passes the farthest point, the system can enter the state of readjusting the length. In this way, the purpose that the unidirectional rotating motor repeatedly adjusts the position of the movable pulley block to reach an optimal state is achieved. At this time, the forces satisfy the following relationship: F_pull rope (50% motor driving force) < F_re-compression force of elastic member 364 < F_pull rope (80% motor driving force) < F_pull rope contraction force that causes discomfort to the animal.

[0053] Therefore, by collecting data at a fixed sampling frequency for a period of time (e.g., 1 minute), the number N of instances where the tension value is less than K (comfortable tension threshold) is determined. Then, by giving the generator motor a power-on time t=N*M (unit time), the above detection and motor action are repeated until the tension value is close to being greater than K but less than NS (slightly uncomfortable tension value). In this way, the chewing jaw perception can be adjusted to a relatively fixed starting range.

[0054] In an optional embodiment, the cross-sectional area of ​​the movable block 362 on the surface perpendicular to the axial direction of the driven gear 330 is larger than the cross-sectional area of ​​the first slide groove 361; this is to prevent the movable block 362 from leaking out of the first slide groove 361 and detaching from the housing of the movable pulley assembly 360; for example, the housing of the movable pulley assembly 360 has a cavity for accommodating the movable block 362.

[0055] See Figures 3-9 As shown, in an optional embodiment, the first chewing power generation pull rope 370 and the second chewing power generation pull rope 380 extend from two opposite surfaces of the chewing power generation housing 310, respectively.

[0056] In an optional embodiment, the first chewing power generation pull rope 370 and the second chewing power generation pull rope 380 pass around the main shaft pulley 321 from opposite directions.

[0057] See Figures 3-8 As shown, in an optional embodiment, the animal chewing self-generating system further includes a chewing tension sensor 390. One end of the chewing tension sensor 390 is connected to the tail end of the first chewing power generating cord 370 and the tail end of the second chewing power generating cord 380, respectively, and the other end of the chewing tension sensor 390 is fixedly connected to the chewing power generating housing 310. The chewing tension sensor 390 is used to monitor the movement of the animal's jaw; that is, the chewing tension sensor 390 is connected between the tail end of the first chewing power generating cord 370 and the chewing power generating housing 310, and also between the tail end of the second chewing power generating cord 380 and the chewing power generating housing 310. The chewing tension sensor 390 can be used to monitor the tightening information of the first chewing power generating cord 370 and the second chewing power generating cord 380.

[0058] Since the jaw sizes of different animals and animals of different ages vary, the electric adjustment function of the animal chewing self-generating system 300 can tighten the first chewing power generating cord 370 and the second chewing power generating cord 380. Simultaneously, the chewing tension sensor 390 can monitor changes in tension in real time (adding automatic adjustment based on waveform troughs). Because the animal's jaw will be constantly moving due to chewing after wearing the animal chewing self-generating system, data is collected at a fixed sampling frequency for a period of time (e.g., 1 minute). The number N of instances where the tension value is < K (comfortable tension threshold) is determined. The above detection and generator operation are repeated by providing a given power-on time t = N × M (unit time) for the generator motor until the tension value is close to being greater than K but less than NS (the tension value that causes slight discomfort to the animal). This adjusts the chewing jaw perception to a relatively fixed starting range. In this embodiment, the chewing tension sensor 390 can use CAN bus communication and can act as a CAN bus data aggregation component to coordinate the adjustment of the animal chewing self-generating system.

[0059] This embodiment also provides a sensing cage, including the animal chewing self-generating system 300 described in any of the above embodiments, and also includes a rope 100 for being fitted onto the outer contour of the animal's mouth.

[0060] The rope 100 has a break; the first end of the first chewing power generation rope 370 and the first end of the second chewing power generation rope 380 of the animal chewing self-generating system are respectively connected to the two ends of the break.

[0061] The sensing tether described in this embodiment can effectively convert chewing mechanical energy into electrical energy through an animal chewing self-generating system, thereby facilitating the power supply for animal smart wearable devices. Specifically, when the animal chews and opens its mouth, the rope 100 fitted around the outer contour of the animal's mouth simultaneously pulls the first chewing power generating rope 370 and the second chewing power generating rope 380, causing the main shaft pulley 321 to rotate around a first direction. At this time, the first one-way bearing is locked, the chewing main shaft rotates synchronously with the main shaft pulley 321, and the rotating shaft of the chewing generator 340 generates electricity by rotating with the chewing main shaft.

[0062] See Figure 2 As shown, in an optional embodiment, the sensing cage also includes a connecting part 110; the animal chewing self-generating system 300 is connected to the connecting part 110; the connecting part 110 allows the animal chewing self-generating system 300 to be better worn on the animal.

[0063] The sensing tether provided in this embodiment includes the aforementioned animal chewing self-generating system. The technical features of the disclosed animal chewing self-generating system are also applicable to this sensing tether, and the technical features of the disclosed animal chewing self-generating system will not be repeated here. The sensing tether described in this embodiment has the advantages of the aforementioned animal chewing self-generating system, and the advantages of the disclosed animal chewing self-generating system will not be repeated here.
