[0037] In order to make the purpose, technical scheme and beneficial effects of the present invention more clearly understood, the present invention is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. Certain embodiments of the present invention will be described more comprehensively with reference to the accompanying drawings, in which some but not all embodiments will be shown. In fact, the various embodiments of the present invention can be implemented in many different forms and should not be construed as being limited to the embodiments described herein; rather, these embodiments are provided so that the present invention meets applicable legal requirements.

[0038] In the description of the present invention, it should be noted that the terms "inside", "outside", "upper", "lower", "front", "back" and the like indicate directions or positional relationships based on directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0039] like Figures 1 to 7 As shown, a smart pet collar based on SMA includes a collar base 1, a pressure sensor 2, an SMA action module 3, a temperature sensor 4, a positioning module 51, an electric stimulator, a wireless communication module 53, an LED flexible display screen 54, an acceleration sensor module 55, a battery module 56, a flexible solar panel 57 and a main control chip 6, etc.

[0040] The collar base 1 is an annular structure, and its outer shell is a flexible package, which is used to be put on the neck of the pet.

[0041] The pressure sensor 2 is located inside the collar base 1 and is used to monitor the pressure between the collar base 1 and the neck of the pet. In addition, the pressure sensor 2 is also used to monitor the pulse of the pet.

[0042] The SMA action module 3 is connected to two opposite ends of the collar base 1 respectively, and the SMA action module 3 moves forward or reversely to drive the collar base 1 to tighten or loosen; wherein SMA is the abbreviation of shape memory alloy.

[0043] The main control chip 6 is arranged on the collar base 1 , and the main control chip 6 is respectively connected to the pressure sensor 2 and the SMA action module 3 . The main control chip 6 triggers the SMA action module 3 to act forward or reverse according to the pressure data uploaded by the pressure sensor 2 .

[0044] The SMA action module 3 includes a slot 31, a tongue 32, an SMA spring 33, an SMA wire 34, a first heating unit, and a second heating unit. The slot 31 is connected to one end of the collar base 1, and the tongue 32 is connected to the other end of the collar base 1. The tongue 32 cooperates with the slot 31, and under the action of external force, the tongue 32 can reciprocate relative to the slot 31. One end of the SMA spring 33 is connected to the tongue 32, and the other end of the SMA spring 33 is connected to one end of the collar base 1. The SMA wire 34 is arranged at the edge of the slot 31. The first heating unit is used to heat the SMA spring 33, and the second heating unit is used to heat the SMA wire 34. The main control chip 6 is connected to the first heating unit and the second heating unit by signal, respectively, for triggering the operation of the first heating unit or the second heating unit.

[0045] A first ratchet structure 321 is disposed on the outer side of the latch tongue 32 , and a second ratchet structure 311 is disposed on the inner side of the latch slot 31 . The first ratchet structure 321 cooperates with the second ratchet structure 311 .

[0046] When the SMA spring 33 is heated, the SMA spring 33 tightens, driving the tongue 32 to move toward the slot 31, and the first ratchet structure 321 moves forward relative to the second ratchet structure 311. After the tongue 32 moves to a set position relative to the slot 31, the slot 31 locks the tongue 32. Specifically, the second ratchet structure 311 limits the first ratchet structure 321 from moving backward.

[0047] When the SMA wire 34 is heated, the SMA wire 34 bends in a direction away from the notch of the card slot 31, driving the notch of the card slot 31 to bend outward. At this time, the second ratchet structure 311 is separated from the first ratchet structure 321, and the SMA spring 33, under the action of the elastic force of restoring the original length, drives the latch tongue 32 to move away from the card slot 31 by a set distance. After the latch tongue 32 moves away from the card slot 31 by a set distance, the latch tongue 32 is still in the card slot 31. After the SMA wire 34 cools down, the SMA wire 34 returns to its original shape, thereby driving the notch of the card slot 31 to return to its original shape, so that the card slot 31 re-locks the latch tongue 32, and specifically, the second ratchet structure 311 re-limits the first ratchet structure 321 from moving backward.

[0048] The pressure sensor 2 includes a pressure monitoring electrode 21 and a pressure signal acquisition circuit. The pressure signal acquisition circuit is connected to the pressure monitoring electrode 21 by signal, and the pressure signal acquisition circuit is connected to the main control chip 6 by signal. The pressure data collected by the pressure monitoring electrode 21 is converted into a digital signal by the pressure signal acquisition circuit and uploaded to the main control chip 6. The pressure monitoring electrode 21 is arranged along the extension direction of the collar substrate 1. The area formed by the winding of the pressure monitoring electrode 21 includes a rectangular area 211 located in the middle and a curved area 212 located at both ends. The pressure monitoring electrode 21 is in the shape of a playground as a whole. Among them, the rectangular area 211 of the pressure monitoring electrode 21 lengthens the extension length of the pressure monitoring electrode 21, making it easier to fit the pet's carotid artery, reducing the adjustment work required to align the pressure sensor 2 with the pet's carotid artery when the collar is worn. The pressure monitoring electrode 21 is connected to the pressure signal acquisition circuit via a serpentine flexible PCB, which can allow a certain degree of stretching and reduce the probability of measurement errors caused by pet movement.

[0049] It should be noted that the pressure sensor 2 of this embodiment is used not only for general pressure monitoring, but also for pulse monitoring of pets.

[0050] The temperature sensor 4 includes a temperature monitoring electrode and a temperature signal acquisition circuit located on the inner side of the collar base 1. The temperature signal acquisition circuit is connected to the temperature monitoring electrode signal, and the temperature signal acquisition circuit signal is connected to the main control chip 6. The temperature data collected by the temperature monitoring electrode is converted into a digital signal by the temperature signal acquisition circuit and uploaded to the main control chip 6. The temperature monitoring electrode includes a first main electrode 41 and a second main electrode 42. A plurality of first branch electrodes 411 are arranged at equal intervals on the first main electrode 41, and a plurality of second branch electrodes 421 are arranged at equal intervals on the second main electrode 42. The first branch electrodes 411 and the second branch electrodes 421 are arranged alternately. The temperature monitoring electrode of the temperature sensor 4 adopts this arrangement form, so that the temperature monitoring electrode has a large fitting monitoring area, can measure the average temperature of the area, has a high measurement accuracy, and avoids the problem that the single-point data acquisition of the traditional temperature sensor is greatly disturbed by the environment.

[0051] The pressure sensor 2 and the temperature sensor 4 need to fit the pet's neck well so that the monitoring data can be more accurate. The base of the pressure sensor 2 and the temperature sensor 4 is made of one or more of a variety of polymers such as thermoplastic polyurethane, polyolefin elastomer, polystyrene elastomer, polyamide elastomer, silicone rubber, styrene block copolymer, etc., so that the base of the pressure sensor 2 and the temperature sensor 4 is softer and fits well with the pet's neck.

[0052] During monitoring, on the basis of tightening the collar base 1, the bases of the pressure sensor 2 and the temperature sensor 4 are made softer and fit well with the pet's neck, thereby improving the accuracy of the monitoring data of the pressure sensor 2 and the temperature sensor 4.

[0053] The positioning module 51 is specifically a satellite positioning module. The positioning module 51 is connected to the main control chip 6 by a signal. The positioning module 51 is used to monitor the position of the SMA-based smart pet collar and upload the position information to the main control chip 6 .

[0054] The electric stimulator includes an electric stimulation cathode 521 and an electric stimulation anode 522 located on the inner side of the collar base 1. The electric stimulation cathode 521 and the electric stimulation anode 522 are patch-like structures, which are applied to the inner side of the collar base 1 to achieve a better fit with the pet's neck. The electric stimulator is used to stimulate the pet's neck when powered on, and the electric stimulator signal is connected to the main control chip 6. When stimulation is required on the pet's neck, the main control chip 6 triggers the electric stimulator to power on and run.

[0055] During use, the user can define an electronic fence on the smart terminal in conjunction with the positioning module 51. When the pet is about to leave the electronic fence, the electrical stimulation anode 522 discharges to stimulate the pet to return.

[0056] The wireless communication module 53 is connected to the main control chip 6 for wireless communication with the smart terminal.

[0057] The wireless communication module 53 includes one or more combinations of low-power Bluetooth modules, 4G communication modules, 5G communication modules and WiFi modules. The main control chip 6 transmits the data collected by each sensor module and other modules to the intelligent terminal (such as a PC or mobile phone) by wireless transmission. At the same time, it is equipped with a low-power LED flexible display screen 54. The main control chip 6 sends the basic physiological data of the pet to the LED flexible display screen 54 for display, which is convenient for users to view.

[0058] The acceleration sensor module 55 is arranged in the collar base 1, and the acceleration sensor module 55 signal is connected to the main control chip 6. The acceleration sensor module 55 monitors the acceleration and angular acceleration data of the pet and uploads them to the main control chip 6.

[0059] The battery module 56 is specifically a lithium battery soft pack, which is arranged in the collar base 1 to supply power to each power module. Two flexible solar panels 57 are arranged outside the collar base 1, and the flexible solar panels 57 are electrically connected to the battery module 56 to charge the battery module 56.

[0060] The side of the collar base 1 is provided with a USB interface 58, which is connected to the main control chip 6 for programming the main control chip 6 through the USB interface 58. The USB interface 58 is also electrically connected to the battery module 56 for charging the battery module 56 through the USB interface 58.

[0061] So far, the present embodiment has been described in detail in conjunction with the accompanying drawings. Based on the above description, those skilled in the art should have a clear understanding of the SMA-based smart pet collar of the present invention. For the SMA-based smart pet collar of the present invention, when it is necessary to monitor the pulse, temperature, etc. of the pet, when the pressure value monitored by the pressure sensor 2 is lower than the set value, the main control chip 6 triggers the SMA action module 3 to move forward to drive the collar base 1 to tighten; when it is not necessary to monitor the pulse, temperature, etc. of the pet, or when the pressure value monitored by the pressure sensor 2 is too large, the main control chip 6 triggers the SMA action module 3 to move in the reverse direction to drive the collar base 1 to relax; in this way, the smart pet collar can be adaptively matched with the pet's neck to ensure that the data monitored by the sensor module is accurate and does not affect the healthy growth of the pet. In addition, the sensor module and other modules of the smart pet collar are optimized and improved to improve the accuracy and application performance of the monitoring data of the smart pet collar.
