Description

Technical Field

[0001] This utility model relates to the field of positioning technology equipment, specifically to a positioning card based on the integration of Beidou technology and UWB technology. Background Technology

[0002] With the rapid development of wireless communication technology, positioning devices based on UWB (Ultra-Wideband) technology have been applied in scenarios such as civilian competitive games (e.g., wargames) and indoor personnel tracking due to their short-range, high-precision positioning characteristics. Among existing technologies, such as the positioning card based on UWB technology disclosed in the utility model patent with authorization announcement number CN215117572U, it uses components such as a positioning module, communication module, and main processing module within the main casing to determine the location of personnel and identify their faction. Structurally, it adopts a split rectangular box design and is equipped with a touch screen, voice port, and communication interface, demonstrating a certain degree of practicality.

[0003] However, existing UWB-based positioning cards still have significant limitations: First, positioning relies on a single UWB technology, and its positioning accuracy and stability are highly dependent on the coverage quality of the UWB signal. In open outdoor areas, long-distance scenarios, or complex environments with walls or obstacles, signal attenuation, positioning drift, or even failure are likely to occur, making it difficult to meet the continuous positioning requirements across different scenarios. Second, in the existing structure, the positioning module can only output UWB positioning data and lacks wide-area positioning technology to supplement it. When outside the UWB signal coverage area, it is impossible to effectively track the location of personnel.

[0004] Therefore, in view of the shortcomings of existing UWB positioning cards in terms of scene adaptability, positioning continuity and battery life, there is an urgent need for an improved positioning card that integrates wide-area positioning technology and UWB technology to make up for the above defects and meet the high-precision positioning requirements in more complex scenarios. Utility Model Content

[0005] The purpose of this invention is to propose a positioning card based on the integration of BeiDou technology and UWB technology, so as to solve the technical problem that the single positioning technology of existing positioning cards has limitations in complex environments.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A positioning card based on the fusion of BeiDou and UWB technologies includes a shell comprising an upper shell and a lower shell.

The lower shell also houses a BeiDou positioning module electrically connected to the dual-core main processing module and a second communication antenna associated with the BeiDou positioning module, which is electrically connected to a second communication module accessed by the positioning communication circuit. The upper shell also has a first indicator light and a second indicator light respectively associated with the UWB positioning module and the BeiDou positioning module.

In static scenarios, only the UWB module is activated, while in mobile scenarios, BeiDou positioning can be activated to achieve adaptive adjustment of the positioning mode; 4.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] See Figures 1-3This embodiment proposes a positioning card based on the fusion of BeiDou and UWB technologies, comprising a shell and a built-in positioning and communication circuit. The shell consists of an upper shell 100 and a lower shell 200, which can be assembled in two ways: one is a snap-fit ​​type, where the upper shell 100 and lower shell 200 are respectively provided with snap-fit ​​slots and snap-fit ​​edges; the other is a plug-in type, where the upper shell 100 and lower shell 200 are respectively provided with matching plug-in posts 250 and plug-in interfaces, and positioning posts 260 and positioning holes can also be provided to further improve the stability and accuracy of the plug-in, thereby ensuring the strength and stability of the shell. The upper shell 100 integrates a touch screen 110 and a voice port 120, while the lower shell 200 is equipped with a communication interface 210, with a communication identification block 211 inside the interface.

[0021] The positioning and communication circuit is built into the lower housing 200, and its core includes a dual-core main processing module 300 and a first communication module 241 electrically connected to it, a UWB positioning module, a Beidou positioning module 800, a communication identification block 211, an RFID chip, a voice speaker 121, a touch screen module 111, and a power management module. Among them: The touchscreen module 111 is located inside the touchscreen 110, and the speaker 121 is installed inside the voice port 120. The first communication module 241 is connected to the first communication antenna 240, which works in conjunction with the UWB positioning module. The Beidou positioning module 800 uses a Beidou-3 BDS / GPS dual-mode chip and is isolated from the UWB positioning module by a metal shield. Its matching second communication antenna 230 is electrically connected to the independent second communication module 231. The upper housing 100 is provided with a first indicator light 130 and a second indicator light 140, which are respectively associated with the working status of the UWB positioning module and the Beidou positioning module 800.

[0022] The power system adopts a dual-power independent power supply design: core circuits such as the UWB positioning module are powered by the first power supply 400, while the Beidou positioning module 800 is equipped with a separate second power supply 500. Both are connected to the power management module, which is also electrically connected to the dual-core main processing module 300 to achieve intelligent power supply control. To improve heat dissipation efficiency, a heat dissipation vent 220 is provided in the power supply installation area, with multiple heat dissipation micro-holes distributed on it.

[0023] The specific implementation method is as follows: In this embodiment, the outer shell is made of ABS engineering plastic. The upper shell 100 and the lower shell 200 are assembled by snap-fit. The upper shell 100 has a 2mm wide snap-fit ​​edge, and the lower shell 200 has a 1.8mm deep snap-fit ​​groove at the corresponding position. After assembly, the gap between the seams is less than 0.3mm. A capacitive touch screen 110 is embedded on the surface of the upper shell 100, and a voice port 120 is opened below it. A voice speaker 121 is installed on the inner side.

[0024] A communication interface 210, specifically a Micro-USB interface, is provided on one side of the lower housing 200. The communication identification block 211 inside the interface uses an NFC near-field identification chip, supporting contactless data interaction within 10cm. Heat dissipation vents 220 are provided on the side of the housing, each group containing multiple heat dissipation micro-holes, corresponding to the installation positions of the first power supply 400 and the second power supply 500. The first power supply 400 and the second power supply 500 can specifically be 3.7V / 2000mAh lithium polymer batteries.

[0025] The circuit details are as follows: The processor uses a dual-core processing module, specifically an STM32H743 dual-core MCU; the UWB positioning module uses the DW1000 chipset; and the Beidou positioning module 800 uses the AT6558 dual-mode chip, covered with a 0.2mm thick aluminum alloy shield.

[0026] The power management module uses the BQ24195 chip to achieve dual power supply charging and discharging management and undervoltage protection. When the positioning card is in static positioning mode, the power management module automatically cuts off the output of the second power supply 500, keeping only the UWB module working; when a large error is detected in the UWB positioning, or when a command to activate Beidou positioning is received, the second power supply 500 is automatically activated and dual-mode positioning is started.

[0027] The indicator lights can be LEDs: the first indicator light 130 can be blue and flash once every 3 seconds to indicate that the UWB positioning is valid; the second indicator light 140 can be green and stay on to indicate that the Beidou positioning is locked; the alternating flashing of the two colors indicates that the power supply is lower than the set value.

[0028] This embodiment achieves seamless switching between indoor and outdoor positioning through modular design and intelligent power management, greatly improving positioning accuracy. It can also be applied to personnel positioning management in complex environments such as industrial plants and underground utility tunnels.

[0029] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
