Description

Technical Field

[0001] This utility model relates to a wearable integrated LDS positioning and data transmission antenna structure suitable for homing pigeons, belonging to the field of communication equipment technology. Background Technology

[0002] With the increasing demands for data accuracy in ecological research, wildlife conservation, and sporting events (such as pigeon racing), the quality assessment of animal habitats, the safe identification of bird migration corridors, and the long-term monitoring of the activity trajectories of rare and protected species have become issues of common concern to academia, government, and the public. As a key terminal for obtaining the above-mentioned core information, bird trackers not only fulfill the mission of scientific research instruments but have also fostered a considerable commercial market, and their technological iterations directly affect the depth and breadth of ecological research.

[0003] However, current mainstream products generally adopt a dual-technology approach of "Narrowband Internet of Things (NB-IoT) + Global Navigation Satellite System (GNSS)": the device needs to simultaneously build NB-IoT antenna and GNSS antenna to complete low-power data backhaul and high-precision positioning respectively. Due to the extremely small installation environment of pigeon leg bands and backpack shells, which are constantly moving with the animal, the two antennas have to coexist in close proximity, making it difficult to improve isolation and resulting in significant mutual coupling interference. As a result, the positioning error increases, the initial positioning time is prolonged, and the terminal is forced to increase the transmission power to maintain communication, which in turn leads to increased overall power consumption and shortened battery life, seriously weakening the reliability and data integrity of long-term tracking in the wild.

[0025] The following will provide a clear and complete description of the concept, specific structure, and technical effects of this utility model in conjunction with the embodiments and accompanying drawings, so as to fully understand the purpose, solution, and effects of this utility model. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

Furthermore, the descriptions of "upper," "lower," "left," "right," "top," and "bottom" used in this utility model are only relative to the relative positional relationships of the various components of this utility model in the accompanying drawings.

The term "and / or" as used herein includes any combination of one or more of the associated listed items.

[0028] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various elements, these elements should not be limited to these terms. These terms are only used to distinguish elements of the same type from one another. For example, without departing from the scope of this disclosure, a first element may also be referred to as a second element, and similarly, a second element may also be referred to as a first element.

[0029] See Figures 1 to 5 The present invention relates to a wearable integrated LDS positioning and data transmission antenna structure suitable for homing pigeons, comprising a housing 100, a metal coding ring 200, and a main radiating line 300. The housing 100 is provided with a first semi-circular groove 110, the metal coding ring 200 is placed in the first semi-circular groove 110 and connected to the housing 100, and the main radiating line 300 is disposed on the housing 100 and spatially coupled to the metal coding ring 200.

[0030] Understandably, the spatial coupling between the main radiating circuit and the metal coding ring improves antenna efficiency, and the low power consumption of the main radiating circuit extends battery life. The main radiating circuit not only transmits data about the pigeon's various states to the backend, but also assists GPS positioning via base station signals, enabling more accurate pigeon location in complex environments and improving positioning accuracy.

[0031] Specifically, the metal coding ring 200 couples to the main radiating line 300 to become part of the antenna, which can reduce losses and improve efficiency.

[0032] Specifically, the wearable integrated LDS positioning and data transmission antenna structure for homing pigeons in this utility model is equivalent to an anklet.

[0033] It should be noted that LDS (Laser Distance Sensor) positioning is a navigation technology based on lidar.

[0034] In a specific embodiment, the CAT1 antenna line 310 is spatially coupled to the metal encoding ring 200. It is understood that this spatial coupling improves antenna efficiency, and the low power consumption of the CAT1 antenna extends battery life. The CAT1 antenna line 310 not only transmits data about the pigeon's various states to the backend but also assists GPS positioning via base station signals, enabling more accurate pigeon location in complex environments and improving positioning accuracy.

[0035] See Figure 3 In some embodiments, the housing 100 is provided with a base plate 140. The wearable integrated LDS positioning and data transmission antenna structure suitable for pigeons also includes a motherboard 400. The motherboard 400 is disposed inside the housing 100 and is erected above the base plate 140. The motherboard 400 is fixedly connected to the base plate 140.

[0036] See Figure 4 In a specific embodiment, the base plate 140 is provided with four screw holes, and the main board 400 and the base plate 140 are fixedly connected by screws passing through the screw holes.

[0037] In a specific embodiment, the motherboard 400 is equipped with an ESIM card 420 and a radio frequency module 430 on a PCB board.

[0038] Specifically, the ESIM card 420 maintains communication with the cloud through the antenna of this invention, receives cloud instructions, and promptly reports the location and current status of the homing pigeon to the backend.

[0039] Understandably, the CAT1 antenna connects to the RF module on the PCB board via a pin, providing signal transmission and reception for the ESIM card inside the leg ring. The GPS antenna also operates by connecting to the module on the PCB board via a pin. The CAT1 and GPS antennas are coplanar on the casing. The leg ring is secured with a metal coded ring and then fitted onto the pigeon's leg, thus enabling real-time operation.

[0040] In some embodiments, the motherboard 400 is provided with a pin 410, which is in contact with the main radiation line 300.

[0041] See Figure 5 and Figure 6 In some embodiments, the inner side of the housing 100 corresponding to the main radiating line 300 is provided with a protrusion 150, and the ejector pin 410 contacts the protrusion 150.

[0042] See Figure 5In some embodiments, the main radiating line 300 includes a CAT1 antenna line 310 and a GPS antenna line 320. The motherboard 400 is provided with a plurality of pins 410, which are respectively in contact with the CAT1 antenna line 310 and the GPS antenna line 320.

[0043] Specifically, the CAT1 antenna is the radio frequency antenna of the LTE Cat.1 (Category 1) communication module, and the GPS antenna is the satellite navigation antenna.

[0044] In the application embodiment, the motherboard 400 is provided with four pins 410, two of which are in contact with the CAT1 antenna line 310 and two of which are in contact with the GPS antenna line 320.

[0045] In the application embodiment, the inner side of the housing 100 corresponding to the CAT1 antenna line 310 is provided with two protrusions 150, the inner side of the housing 100 corresponding to the GPS antenna line 320 is provided with two protrusions 150, and the four pins 410 of the main board 400 are in contact with the four protrusions 150 of the CAT1 antenna line 310 and the GPS antenna line 320 respectively.

[0046] In some embodiments, the CAT1 antenna line 310 and the GPS antenna line 320 are coplanarly disposed on the housing 100.

[0047] Specifically, the main radiating line is not limited by the curved or corner surfaces of the shell, allowing for the laying of antenna lines and maximizing space utilization. This satisfies the antenna directionality requirements of the leg ring swaying when the pigeon is in flight or stationary, and also meets the requirement that the GPS faces the sky, thus ensuring positioning accuracy.

[0048] It should be understood that when a homing pigeon flies, its leg band will constantly pitch, roll, and yaw. The circuit is "wrapped" around multiple sides of the shell, forming multiple complementary radiation surfaces; no matter how the leg band shakes, there is always a part of the radiation surface facing the sky or the base station, maintaining the link without interruption.

[0049] In some embodiments, the housing 100 is made of plastic material.

[0050] In some embodiments, the CAT1 antenna line 310 and the GPS antenna line 320 are made using LDS laser engraving technology.

[0051] Specifically, LDS laser engraving technology is used to "engrave" the CAT1 antenna circuitry and GPS antenna circuitry onto the plastic casing. In this way, the antenna becomes part of the casing, eliminating the need for additional parts, reducing the overall weight, and improving the antenna's portability.

[0052] It should be understood that, in order to maximize the use of space, the CAT1 antenna and GPS antenna are installed on a small, usable plastic surface. The main radiating circuitry is contacted via pins on the motherboard, reducing the bottleneck caused by space constraints due to the antenna's need for ground-based radiation.

[0053] Specifically, LDS (Laser Direct Structuring) is an additive manufacturing method that combines "three-dimensional plastics + laser activation + chemical plating".

[0054] See Figure 1 In some embodiments, the wearable integrated LDS positioning and data transmission antenna structure suitable for homing pigeons further includes: a buckle 500 connected to the housing 100, and a metal coding ring 200 placed between the buckle 500 and the housing 100.

[0055] See Figure 2 In some embodiments, a first protrusion 510 is provided on the left side of the buckle 500, and a second semicircular groove 120 is provided on the left side of the first semicircular groove 110. The second semicircular groove 120 and the first protrusion 510 cooperate with each other to connect the outer shell 100 and the buckle 500.

[0056] In a specific embodiment, a second protrusion 520 is provided on the right side of the buckle 500, and a third protrusion 130 is provided on the right side of the first semi-circular groove 110. The third protrusion 130 and the second protrusion 520 cooperate with each other to connect the outer shell 100 and the buckle 500.

[0057] In a specific embodiment, the second protrusion 520 is provided with a fourth protrusion 521, and the third protrusion 130 is provided with a through hole 131. The second protrusion 520 and the third protrusion 130 are fixedly connected by the cooperation of the through hole 131 and the fourth protrusion 521.

[0058] In the application embodiment, the upper and lower ends of the left side of the buckle 500 are respectively provided with two first protrusions 510, the upper and lower ends of the right side of the buckle 500 are respectively provided with two second protrusions 520, and the upper and lower ends of the right side of the first semi-circular groove 110 are respectively provided with two third protrusions 130.

[0059] In a specific embodiment, the buckle 500 has a hole in the middle.

[0060] It should be understood that the buckle is used to secure the entire ankle ring, and its structure is a movable reverse buckle. Figure 3 In the middle, the rectangular component is the battery, used to power the motherboard. After the pigeon's claws are closed, they are passed through the metal coding ring, then the metal coding ring is inserted into the plastic part of the foot ring, and finally the buckle is fastened.

[0061] Specifically, the main radiating circuit adopts LDS laser engraving, which saves equipment space and reduces the weight of the equipment itself; the GPS antenna and CAT1 antenna are coplanar, and the main radiating circuit is contacted through the pins on the motherboard, so that the ground of the motherboard participates in the radiation, thereby improving the antenna efficiency and achieving faster, more accurate, more detailed positioning with better directionality.

[0062] It should be understood that this invention discloses a wearable leg band for homing pigeons. The outer shell surface integrates positioning and data transmission antennas using laser direct forming (LDS) technology, forming a low-profile, multi-band miniaturized antenna system. The leg band incorporates a GPS module, an embedded chip, and a SIM card. Relying on the mobile internet, it transmits the pigeon's vital signs, location, flight trajectory, and surrounding weather information in real time via a mobile app, allowing users to monitor the pigeon's status at any time. This invention utilizes the spatial coupling between the LDS antenna body and the metal barcode ring (i.e., the aforementioned metal encoding ring) to effectively extend the current path and improve radiation efficiency, thereby overcoming the problem of signal attenuation in complex environments. The antenna consists of a CAT1 main antenna and a GPS antenna, both designed coplanarly and fed through a motherboard pin. It combines the advantages of simple structure, light weight, low cost, and high efficiency, making it suitable for wearable tracking devices for animals such as homing pigeons.
