BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Figure 1 It is a schematic diagram of the system structure of the present invention. DETAILED DESCRIPTION

[0027] In today's business environment, the security protection of display prototypes is crucial. Traditional wired anti-theft devices have many problems, such as the restraint of connecting wires, inconvenient disassembly and assembly, lack of real-time monitoring, etc. The wireless anti-theft device using Bluetooth AOA / DOA technology proposed in the present invention aims to solve these problems and provide an efficient, convenient and intelligent anti-theft solution.

[0028] The AOA Bluetooth base station is the core component of the entire system, which includes a signal transceiver module, a position calculation module, and a data upload module. The signal transceiver module uses a high-performance Bluetooth chip, model CSR8811, with an operating frequency range of 2.4GHz-2.48GHz, which can stably communicate with the Bluetooth beacon tag of the display prototype device. The position calculation module is based on the advanced AOA / DOA algorithm and can accurately calculate the position of the display prototype with a position calculation accuracy of centimeters. The data upload module supports multiple uplink network connection methods such as 4G communication, wired network and WIFI to adapt to different application scenarios.

[0029] For the display samples with built-in Bluetooth function, the beacon function is added through secondary development. In the secondary development process, the Nordic nRF52832 development tool is used to enable the Bluetooth signal to carry specific identification and location information. For the display samples without Bluetooth function, a specially designed Bluetooth beacon tag is attached, which includes a signal transmission module and an identification coding module. The transmission power of the signal transmission module is 5dBm, and the identification coding module uses a 16-bit CRC encoding method to ensure that each tag has a unique identifier.

[0030] The display prototype charging tray provides two power supply methods: wireless charging and POGOPI N easy-to-detach connection. Wireless charging uses electromagnetic induction technology, and the charging efficiency reaches 75%. The POGOPI N easy-to-detach connection method ensures the stability and convenience of the power connection, and its contact resistance is less than 0.1 ohms. The charging tray also includes a charging control module and a fixed support module. The charging control module can automatically adjust the charging power according to the power status of the display prototype. The fixed support module uses aluminum alloy material and a triangular support structure design, which can firmly support the display prototype.

[0031] The server side includes two options: cloud server and local private server. The cloud server is built on Alibaba Cloud ECS and has powerful data processing and storage capabilities. The local private server uses Intel Xeon E5-2680v4 processor, 32GB memory and 1TB SSD hard disk configuration, as well as Windows Server 2019 operating system and SQL Server 2019 database system, which can meet the needs of users with high data security requirements. The algorithm engine functions of the server side include location algorithm module and early warning judgment module. The location algorithm module can calculate the location and movement trajectory of the display prototype in real time. The early warning judgment module determines whether to trigger an early warning or alarm according to the preset rules. The data processing function includes data storage module and analysis and statistics module. The data storage module uses the SQL Server 2019 database system and can store a large amount of operation logs and equipment management data. The analysis and statistics module can conduct in-depth analysis of these data and provide users with valuable information.

[0032] The PC client provides an intuitive and easy-to-use management interface through which users can manage devices, query operation logs, generate statistical reports, and perform operation and maintenance operations. The client software is developed based on the C# language and .NET Framework 4.7 development framework and runs on the Windows 10 operating system.

[0033] The mobile client is suitable for mobile smart terminals such as mobile phones, PADs and tablets. Users can manage and monitor the display prototypes through the mobile client anytime and anywhere. The mobile client application is developed using the Flutter framework and Dart language, and supports Android 9.0 and above and iOS 12.0 and above operating systems.

[0034] According to the size and layout of the exhibition area, the installation location of the AOA Bluetooth base station should be reasonably planned. Generally speaking, in larger exhibition halls, a base station is installed every 10 meters to ensure that there is no dead angle in the coverage. The base station is installed at a height of 2.5 meters and an angle of 45 degrees to obtain the best signal reception effect. During the installation process, use expansion screws and brackets to fix it to ensure that the base station is firmly installed.

[0035] For display samples with built-in Bluetooth function, follow the secondary development operation guide to upgrade and configure the software. For display samples with Bluetooth beacon tags, stick the tags at the bottom center of the samples to ensure that the tags fit tightly to the samples and do not affect the appearance and normal use of the samples.

[0036] Place the display prototype charging tray in a suitable position on the display table to ensure that the display prototype can be easily placed on the tray for charging and fixing. Connect the power line of the charging tray to ensure a stable power supply.

[0037] Select a cloud server or a local private server according to user needs, and perform corresponding server configuration and software installation. Install management applications on PC clients and mobile clients to perform user registration and login settings.

[0038] In order to verify the performance and effect of this wireless anti-theft device, a series of operation tests were conducted and relevant data were collected. The following are some of the test data and results:

[0039]

[0040] Place display prototypes at different locations in the display area, obtain the location information of the display prototypes through the system, and compare it with the actual location. The test results show that the system can accurately locate the location of the display prototypes, with a positioning accuracy of centimeters, meeting the precise positioning needs of indoor sales stores, showrooms and other places;

[0041] The exhausted demo device was placed on the charger tray, and the charging time and power increase were recorded. The test results showed that both wireless charging and POGOPIN easy-to-detach charging methods could charge the demo device quickly and stably, and the charging efficiency was in line with expectations.

[0042] The system was run continuously for 24 hours to monitor the stability and delay of data upload. The results showed that the system was able to stably upload the location, status and other data of the display prototype to the server, with zero data transmission interruptions and an average delay of less than 0.5 seconds, ensuring the real-time and reliability of the data.

[0043] The system response time was measured by simulating the display prototype leaving the normal experience area, warning area and alarm area. The test results showed that the system was able to issue warning and alarm prompts in a timely manner, with a warning response time of less than 2 seconds and an alarm response time of less than 4 seconds, effectively ensuring the safety of the display prototype.

[0044] The present invention completely abandons the connecting wires of traditional wired anti-theft devices, avoiding the problems of long wires that are easy to get tangled and short wires that affect customer experience. It also facilitates store display updates and no longer needs to be fixed with glue, reducing the trouble of disassembly and assembly and the risk of damage to prototypes. The wireless anti-theft device enables display samples to be installed separately and can be easily collected in a safe place for safekeeping when not in business, greatly improving safety and avoiding the possibility of theft due to fixed display. The power supply method of wireless charging and POGOPIN easy-to-detach connection solves the problem of wired power supply lines being entangled, improving the convenience and safety of charging, and can monitor the operation of the display prototype in real time and collect data, which can be uploaded to the server for analysis. This not only helps stores understand customers' product preferences and operating habits and optimize operational strategies, but also ensures the safe operation of equipment and makes it traceable. It uses Bluetooth AOA / DOA technology to achieve centimeter-level precise positioning. By setting normal experience areas, early warning areas and alarm areas, while ensuring customers' free experience, it can issue early warnings and alarms in a timely and effective manner to improve anti-theft effects. It is suitable for a variety of display samples with Bluetooth functions or attachable Bluetooth beacon tags. Whether it is electronic products such as mobile phones and laptops, or high-tech exhibits such as smart robots and drones, they can be effectively protected. Customers can freely experience the various functions of the display prototypes without the constraints of connecting wires, which improves customer satisfaction and willingness to buy. Through the IOT management platform, remote management and monitoring of the display prototypes are realized, which is convenient for staff to understand the status of the equipment anytime and anywhere, and improves management efficiency.

[0045] The wireless anti-theft device using Bluetooth AOA / DOA technology of the present invention effectively solves the problems existing in traditional anti-theft devices through innovative technology and design, and provides a more advanced, reliable and convenient anti-theft solution for the display industry. In practical applications, it has achieved remarkable results and has been highly recognized by users.

[0046] In the future, as Bluetooth technology continues to develop and its application scenarios continue to expand, we will continue to optimize and improve this system, improve its performance and functions, and provide users with better services.
