Technical Field

[0001] This invention provides a miniaturized ear-shaped positioning device based on a hybrid power supply system and active signal enhancement technology, belonging to the field of pet positioning technology. Background Technology

[0002] As people's living standards continue to improve, many people have started to keep various pets. Pets are said to be able to understand human emotions, and the bond between people and their pets is very deep. Pets also hold a special place in the home. To prevent pets from getting lost, pet trackers are usually used to locate them.

[0003] Most existing pet trackers are collar-type trackers, which can basically meet normal usage needs, but they still have corresponding drawbacks: Traditional collar-type trackers rely on a single battery for power, and the miniaturized devices have insufficient battery life (usually <72 hours), and frequent charging affects the user experience; poor signal penetration: complex indoor environments (such as multi-story residential buildings, concrete walls) cause severe attenuation of GPS / BLE signals, with a positioning failure rate of >30%; low wearing comfort: the collar is easily broken by pets and affects the animal's natural behavior; limited functionality: lacking the ability to simultaneously monitor the pet's physiological state. Summary of the Invention

[0004] The technical problems solved by this invention are: insufficient battery life, poor signal penetration, low wearing comfort, and limited functionality.

[0005] To address the technical problem, the present invention provides the following technical solution: a miniaturized earring-type positioning device based on a hybrid power supply system and active signal enhancement technology, comprising a titanium alloy shell, a zirconium oxide ceramic wave-transparent layer on the inner wall of the titanium alloy shell, a magnetic earring and a safety contact electrode on the outer side of the titanium alloy shell, a transparent nanowire solar film electrically connected to the safety contact electrode on the surface of the magnetic earring, and a communication layer, a processing layer and a hybrid power supply layer inside the titanium alloy shell, wherein the communication layer includes a UWB / BLE dual-mode antenna array, an IMU inertial navigation module and a signal processing FPGA module.

The supercapacitor is electrically connected to a transparent nanowire solar film.

[0008] Furthermore, the piezoelectric ceramic sheet has a thickness of 3mm, and it is fixed to the inner wall of the titanium alloy shell by AB glue. The supercapacitor is soldered to the pins of the energy management IC module.

[0009] Furthermore, the zirconium oxide ceramic wave-transparent layer has a thickness of 0.2 mm, and the titanium alloy shell has a diameter of 8 mm and a thickness of 1.2 mm.

[0010] Furthermore, the processing layer also includes an integrated micro PPG sensor and a temperature compensator located within a titanium alloy shell, for monitoring capillary blood flow in the auricle.

[0011] The beneficial effects of this invention are as follows: This invention can solve the problem of long-term power supply for micro devices in continuous positioning mode (target battery life ≥ 30 days), has strong battery life, improves the reliability of signal transmission in complex indoor environments (positioning success rate > 95%), has better signal penetration, achieves seamless wearing through ear-like design, is comfortable to wear, has rich functions, and integrates multimodal sensors to achieve integrated positioning and health monitoring.

Detailed Implementation

[0021] The invention will be further described below with reference to the accompanying drawings.

[0022] According to the appendix Figure 1 , 2 As shown in Figures 3 and 6: This invention provides a miniaturized earring-style positioning device based on a hybrid power supply system and active signal enhancement technology, including a titanium alloy shell 101. The titanium alloy shell 101 internally houses a communication layer, a processing layer, and a hybrid power supply layer. The communication layer includes a UWB / BLE dual-mode antenna array 201, an IMU inertial navigation module 202, and a signal processing FPGA module 203. The processing layer includes a flexible PCB board 301, a GPS positioning module 302, a BLE 5.2 Mesh network module 303, and an environmental perception module 304. The flexible PCB board 301 and the GPS positioning module... Module 302, BLE5.2 Mesh network module 303, environmental perception module 304, UWB / BLE dual-mode antenna array 201, IMU inertial navigation module 202, and signal processing FPGA module 203 are all electrically connected. The flexible PCB board 301 adopts a position compensation algorithm. When GPS fails, the environmental perception module 304 senses and detects the GPS signal strength. If it is greater than a threshold, GPS positioning is used. If it is less than a threshold, a UWB scan is performed. 3D positioning is achieved through UWB ranging and inertial navigation IMU with an error of <1.5 meters. A dual-frequency communication architecture is adopted: GPS / BLE 5.2 dual-mode standby, automatic switching to low-power mode, dynamic beamforming, and the UWB / BLE dual-mode antenna array 201 uses indoor reflected signals to enhance penetration capability.

[0023] As an optional embodiment, a zirconia ceramic wave-transparent layer 102 is provided on the inner wall of the titanium alloy shell 101. The zirconia ceramic wave-transparent layer 102 is hot-pressed onto the inner side of the titanium alloy shell 101. The thickness of the zirconia ceramic wave-transparent layer 102 is 0.2 mm. The diameter of the titanium alloy shell 101 is 8 mm and the thickness is 1.2 mm. The outer side of the titanium alloy shell 101 is provided with a magnetic ear stud 103 and a safety contact electrode. Specifically, the wave-transparent layer is replaced with a polyimide-based composite material with a dielectric constant <6. The piezoelectric element is removed, and the battery life is reduced to 7 days, which is used for budget-sensitive products to reduce costs.

[0024] As per the instruction manual Figure 1 , 4 As shown in Figure 5: The magnetic ear stud 103 has a tensile strength ≥5N to prevent it from falling off the pet's ear. The surface of the magnetic ear stud 103 is provided with a transparent nanowire solar film 104 electrically connected to the safety contact electrode. The hybrid power supply layer includes a main power supply unit and an auxiliary power supply unit. The main power supply unit includes a lithium battery module 401 and a Qi wireless charging module 402 electrically connected to the lithium battery module 401. The Qi wireless charging module 402 is used to charge the lithium battery module 401. The auxiliary power supply unit includes a piezoelectric ceramic sheet 403, an energy management IC module 404 electrically connected to the piezoelectric ceramic sheet 403, and a supercapacitor 405 for charging the lithium battery module 401. A miniature pendulum mechanism 406 powered by a capacitor 405 is included. The supercapacitor 405 is electrically connected to a transparent nanowire solar film 104. The piezoelectric ceramic sheet 403 has a thickness of 3 mm and is fixed to the inner wall of the titanium alloy shell 101 with AB glue. The supercapacitor 405 is soldered to the pins of the energy management IC module 404. Specifically, kinetic energy generation: the miniature pendulum mechanism 406 generates electricity at a frequency of 2-5 Hz using the natural shaking of a pet's ear, with a conversion efficiency ≥15%. Light energy harvesting: the transparent nanowire solar film 104 is integrated into the magnetic ear stud 103, outputting a power of 0.8 mW / cm² under 200 lux illuminance. 2 Adaptive management IC: prioritizes the conduction of the solar / kinetic input path voltage threshold of 2.7V; Battery switching switch: activates the lithium battery only when the supercapacitor voltage is <2.4V.

[0025] As an optional embodiment, the processing layer further includes an integrated miniature PPG sensor and a temperature compensator located within the titanium alloy housing 101, used to monitor capillary blood flow in the auricle, calculate heart rate and blood oxygen in real time, and use the temperature compensator to eliminate the influence of ambient temperature on physiological parameters, as shown in the appendix to the specification.

[0030] Example 2: Power Supply Scenario

[0031] Outdoors on sunny days: 85% solar power supply + 12% kinetic energy power supply;
