Description

Technical Field

[0001] This utility model relates to the field of multi-screen display cabinet technology, specifically a UWB positioning multi-screen display cabinet. Background Technology

[0002] Ultra-Wave Broadband (UWB) is a carrier-free communication technology that uses narrow, non-sinusoidal pulses in the nanosecond to microsecond range to transmit data. Some call it a revolutionary advancement in radio technology, believing it will become the mainstream technology for short-range wireless communication in the future. In general, UWB was initially used for high-speed, short-range data transmission, and in recent years, its sub-nanosecond ultra-narrow pulses have been used abroad for precise, short-range indoor positioning.

[0003] In a multi-screen interactive display mode, because it is impossible to quantify the attractiveness data of each exhibit, merchants find it difficult to distinguish between true "hot-selling" and "slow-moving" products. This results in valuable display spaces being occupied by low-attention exhibits for a long time, which not only wastes scarce display resources but also directly affects the exposure and sales conversion of potential products. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A UWB positioning multi-screen display cabinet includes a display mechanism, a calculation mechanism, and a verification mechanism. The display mechanism includes a support frame and multiple curved screens that are attached to and fixedly enclosed around the outside of the support frame in pairs. The calculation mechanism includes a top shell fixed to the top of the support frame, a main control MCU and four UWB base stations fixed to the top of the top shell, and multiple UWB wristbands located on one side of the support frame. The UWB base stations and UWB wristbands are electrically connected to the main control MCU. The verification mechanism includes a monitor located on one side of the support frame, a mounting arm fixed to the monitor's housing, and a memory fixed to the inner top surface of the top shell. The monitor is electrically connected to the main control MCU.

[0007] By adopting the above technical solution, after visitors put on UWB wristbands and enter the area around the support structure, all UWB base stations continuously communicate with the UWB wristbands to measure the flight time of the wireless signal and send the raw ranging data to the main control MCU in real time. The main control MCU implements positioning algorithms (such as TDOA or TOA) to calculate the real-time precise coordinates (X, Y) of the visitors based on the ranging data from multiple UWB base stations. Then, it performs "dwelling analysis" and "path analysis" on the visitors' behavior. This data is plotted into a "heat map of attention" to help merchants know which products are more popular, thereby achieving product screening, improving the utilization rate of display resources, and increasing the exposure and sales conversion of potential products.

[0008] In a preferred embodiment, the present invention can be further configured such that: a circular groove and a plurality of fan-shaped grooves are provided on the inner top surface of the top shell, and the plurality of fan-shaped grooves are equally spaced and surround the outer side of the circular groove.

[0009] In a preferred embodiment, the present invention can be further configured such that the main control MCU and the memory are both located inside the circular slot, the memory is located on one side of the main control MCU, and the multiple UWB base stations are respectively located inside multiple sector slots.

[0010] In a preferred embodiment, the present invention can be further configured such that: the top end of the mounting arm has multiple threaded holes, which are equally spaced and arranged in a ring.

[0011] In a preferred embodiment, the present invention can be further configured such that: infrared sensors are embedded on both the front and rear sides of the support frame, the two infrared sensors are respectively located on the top of the two curved screens, and the two infrared sensors are electrically connected to the main control MCU.

[0012] In a preferred embodiment, the present invention can be further configured such that: an ambient light sensor is embedded in the front side of the support frame, and the ambient light sensor is electrically connected to the main control MCU.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. In this utility model, after visitors put on the UWB wristband, they enter the area around the support frame. All UWB base stations continuously communicate with the UWB wristband, measure the flight time of the wireless signal, and send the raw ranging data to the main control MCU in real time. The main control MCU implements a positioning algorithm (such as TDOA or TOA) to calculate the real-time accurate coordinates (X, Y) of the visitors based on the ranging data from multiple UWB base stations. Then, it performs "stay analysis" and "path analysis" on the visitors' behavior. This data is plotted into a "heat map of attention" to help merchants know which products are more popular, thereby achieving product screening, improving the utilization rate of display resources, and increasing the exposure and sales conversion of potential products.

[0015] 2. In this utility model, when multiple curved screens display products, the monitor records the display area in real time, and then the monitoring information is uploaded to the memory by the main control MCU, which facilitates the subsequent comparison of the test results by the staff and avoids false detection.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0028] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0029] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a UWB positioning multi-screen display cabinet.

[0030] Example 1:

[0031] Combination Figure 1-5 As shown, the present invention provides a UWB positioning multi-screen display cabinet, including a display mechanism 100, a calculation mechanism 200 and a verification mechanism 300. The display mechanism 100 includes a support frame 110 and multiple curved screens 120 that are attached to each other and fixedly surrounded on the outside of the support frame 110.

[0032] The measuring mechanism 200 includes a top shell 210 fixedly connected to the top of the support frame 110, a main control MCU 220 fixedly connected to the top of the top shell 210, four UWB base stations 230, and multiple UWB wristbands 240 disposed on one side of the support frame 110. The UWB base stations 230 and UWB wristbands 240 are all electrically connected to the main control MCU 220.

[0033] The verification mechanism 300 includes a monitor 310 located on one side of the support frame 110, a mounting arm 320 fixedly connected to the housing of the monitor 310, and a memory 330 fixedly connected to the inner top surface of the top shell 210. The monitor 310 is electrically connected to the main control MCU 220.

[0034] Furthermore, the inner top surface of the top shell 210 is provided with a circular groove and multiple fan-shaped grooves. The multiple fan-shaped grooves are equally spaced and surround the outer side of the circular groove. The opening of the circular groove and multiple fan-shaped grooves provides installation space for installing the main control MCU 220 and the memory 330.

[0035] Furthermore, both the main control MCU 220 and the memory 330 are located inside the circular slot. The memory 330 is located on one side of the main control MCU 220, and multiple UWB base stations 230 are located inside multiple sector-shaped slots, respectively. This separate storage of the main control MCU 220, UWB base stations 230, and memory 330 avoids signal interference between base stations and ensures the stability and accuracy of the positioning signal.

[0036] Furthermore, the top of the mounting arm 320 is provided with multiple threaded holes, which are equally spaced and arranged in a ring. The threaded holes allow the mounting arm 320 to be firmly connected to the exhibition hall wall.

[0037] Example 2:

[0038] Combination Figure 1 and Figure 2 As shown, based on Embodiment 1, infrared sensors 400 are embedded on both the front and rear sides of the support frame 110. The two infrared sensors 400 are located on the top of the two curved screens 120 respectively. Both infrared sensors 400 are electrically connected to the main control MCU 220. The two infrared sensors 400 can monitor in real time whether someone is approaching in front of the display case. When someone enters the monitoring range, the infrared sensor 400 will transmit a signal to the main control MCU 220. The main control MCU 220 will then react accordingly according to the preset program and adjust the display content of the curved screen 120 to enhance the visitor experience and interactivity.

[0039] Example 3:

[0040] Combination Figure 1-2 As shown, in the above embodiment, an ambient light sensor 500 is embedded in the front side of the support frame 110. The ambient light sensor 500 is electrically connected to the main control MCU 220. The main control MCU 220 dynamically adjusts the brightness of each curved screen 120 according to the data of the ambient light sensor 500, so as to ensure that the content is clearly visible under strong light and not dazzling under weak light, while achieving the purpose of energy saving.

[0041] The working principle and usage process of this utility model are as follows: In the initial state, the support frame 110 with the curved screen 120 is placed in the exhibition area (campus, memorial hall, etc.). When the device is put into actual use, visitors wear UWB wristbands 240 beforehand. When they enter the area around the support frame 110, all UWB base stations 230 continuously communicate with the UWB wristbands 240 to measure the flight time of the wireless signal and send the original ranging data to the main control MCU 220 in real time. The main control MCU 220 implements a positioning algorithm (such as TDOA or TOA) and calculates the real-time accurate coordinates (X, Y) of the UWB wristband 240 (visitor) based on the ranging data from multiple UWB base stations 230. Then, the behavior of the visitors is analyzed.

[0042] Dwell time analysis: Record the time when a user's coordinates remain unchanged in front of a curved screen at 120 degrees, and determine it as "dwell time";

[0043] Path analysis: Records continuous changes in user coordinates and generates a "movement path";

[0044] Then, this data is plotted into a "heatmap of popularity," which aggregates the coordinate data of all users over a period of time and generates dotted lines of varying shades on a virtual map. This allows us to determine which products are more popular and which are less popular, thus enabling product filtering. This improves the utilization rate of display resources and increases the exposure and sales conversion of potential products. At the same time, the monitor 310 records the display area in real time, and the monitoring information is then uploaded by the main control MCU 220 to the memory 330, facilitating subsequent comparison of the detection results by staff and avoiding false positives or negatives.

[0045] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
