[0002] In today's business environment, the safety and convenience of product display are the focus of merchants. For various high-value display samples, such as electronic products, jewelry, etc., effective anti-theft measures are indispensable.

[0003] Traditional anti-theft devices mainly use wired connections, which have many significant defects. First, the length of the connected safety wire, rope, and charging cable is difficult to control. If it is too long, it is easy to cause entanglement, affecting the customer experience and the appearance of the store display; if it is too short, it will limit the customer's operation of the sample and even affect its normal functional display. Second, the wired connection method is inconvenient to fix at both ends. In order to achieve the fixing effect, glue is often used for fixing, which is extremely time-consuming when updating the display samples and may also cause damage to the prototype. Third, traditional anti-theft devices usually do not have real-time monitoring data collection functions, and cannot obtain key information such as the demonstration of the display prototype and the preferences of customers, making it difficult to support merchants in making accurate operational decisions. Fourth, in the conversion between business display and non-business storage, traditional devices perform poorly and cannot meet the needs of display effect and safe storage at the same time. Moreover, the charging connection method is single and not flexible enough, which often brings inconvenience to the use of display samples.

[0028] With the continuous advancement of technology and the growing market demand, higher requirements are placed on the safety and convenience of commodity display. Traditional anti-theft devices often have many limitations and cannot meet the complex needs of modern commercial environments. The present invention provides a wireless anti-theft device using UWB technology, which aims to provide an efficient, accurate and flexible anti-theft solution for various display scenarios.

[0029] This wireless anti-theft device is mainly composed of four parts: UWB base station, display prototype charging holder, display prototype device UWB tag and IOT management platform. Its working principle is based on the high-precision positioning and real-time communication capabilities of UWB technology. Through the collaborative work of various components, it can realize all-round anti-theft monitoring of the display prototype.

[0030] UWB base station: The UWB base station includes a UWB chip one-to-many base station and an upload communication network hardware. The UWB chip one-to-many base station uses an advanced ultra-wideband technology chip with high-precision ranging and positioning capabilities. The upload communication network hardware includes 4G communication modules, wired network modules, and WIFI modules to adapt to different network environments. In actual applications, the installation location of the UWB base station is reasonably planned according to the area and layout of the exhibition venue. Usually, the UWB base station is installed high on the ceiling or wall to ensure uniformity and unobstructed signal coverage. For larger exhibition areas, multiple UWB base stations may be required to work together to improve the accuracy and reliability of positioning through triangulation or multilateral positioning algorithms. The UWB base station continuously transmits ultra-wideband pulse signals and receives echo signals from the UWB tags of the display prototype equipment. By measuring the flight time, arrival angle and other parameters of the signal, the real-time location of the display prototype is calculated. At the same time, the collected data is transmitted to the IOT management platform through the upload communication network hardware.

[0031] Display prototype charger tray: The display prototype charger tray consists of a base, a support structure, a charging interface and a circuit. The base provides stable support, and the support structure can be adjusted according to the shape and size of the display prototype. The charging interface includes a wireless charging module and a POGOPIN easily detachable power module. The wireless charging module works based on the principle of electromagnetic induction. When the display prototype is placed on the charger tray, the internal induction coil interacts with the transmitting coil in the tray to generate an alternating magnetic field, thereby realizing the wireless transmission of electrical energy. In order to improve the charging efficiency and stability, intelligent power regulation technology is adopted to automatically adjust the output power according to the battery status and charging requirements of the display prototype. The POGOPIN connector consists of a needle, a spring and a needle tube. When the display prototype is connected to the charger tray, the needle contacts the contact on the display prototype, and the spring provides appropriate pressure to ensure a good electrical connection. This connection method has the advantages of easy plugging and unplugging and reliable contact. It is suitable for scenarios where the display prototype needs to be frequently replaced or fast charging. The circuit inside the charger tray has overvoltage protection, overcurrent protection, short circuit protection and other functions to ensure the safety and reliability of the charging process. At the same time, the charging status and related data are uploaded in real time through communication with the UWB base station and IOT management platform.

[0032] UWB tag of the display prototype device: The UWB tag adopts a small and thin design so that it can be pasted or installed on the display prototype without affecting its appearance and use. The tag integrates UWB communication chip, encryption communication module, anti-interference signal enhancement unit and power management module. The encryption communication module uses encryption algorithms such as Advanced Encryption Standard (AES) to encrypt the data transmitted between the UWB base station. Before each communication, a temporary key is generated through the key exchange protocol to ensure the confidentiality and integrity of the data. The signal enhancement unit consists of a high-performance filter, amplifier and antenna. The filter can effectively filter out interference signals from other wireless devices, and the amplifier amplifies the power of the transmitted and received signals to increase the signal strength and transmission distance. The antenna adopts a directional or omnidirectional design, which is selected according to the actual application scenario to optimize the signal coverage. The UWB tag is usually powered by a small button battery or a rechargeable lithium battery. The power management module is responsible for monitoring the battery power and sending an alarm signal to the IOT management platform when the power is too low. At the same time, the battery life is extended through low-power design technologies such as sleep mode and dynamic power adjustment.

[0033] IOT Management Platform:

[0034] 1. PC client: The PC client has an intuitive and concise user interface, which displays real-time information such as the display prototype location map, working status, charging status, etc. The data is presented in the form of charts, lists, etc., which is convenient for managers to quickly obtain key information. It supports the addition, deletion, and modification of UWB base stations, display prototype chargers, and display prototype device UWB tags. A unique identifier and related parameters can be set for each device, such as device name, location, group, etc. Managers can delineate safety areas and warning areas on the map. When the display prototype leaves the safety area and enters the warning area, the system will issue a pop-up window or voice prompt; if it continues to leave the warning area, the system will trigger an audible and visual alarm, and can analyze the collected data, such as the display prototype's usage frequency, residence time, movement trajectory, etc. Generate detailed reports based on the analysis results to provide data support for business decisions;

[0035] 2. Mobile client: The mobile client allows managers to view the real-time status of the display prototype anytime and anywhere through mobile devices such as mobile phones and PADs. Through push notifications, managers can receive alarm information and important event reminders in a timely manner. In an emergency, managers can remotely control certain functions of the display prototype through the mobile client, such as locking the device, stopping charging, etc. Combined with the GPS function of the mobile phone, it provides managers with navigation guidance to the location of the display prototype, which facilitates and quickly handles abnormal situations;

[0036] 3. Server: The server uses a high-performance database system, such as MySQL or MongoDB, to store large amounts of device data, location information, user operation records, etc. Through the data processing engine, real-time data is quickly analyzed and calculated to extract valuable information, and the positioning algorithm and early warning algorithm are continuously optimized to improve the accuracy and response speed of the system. At the same time, according to the changes in the actual application scenarios, the setting rules of the safety area and the early warning area are adjusted, and integrated with other security systems and monitoring systems to achieve data sharing and collaborative work. For example, when the display prototype triggers an alarm, it is linked to the video surveillance system, and the relevant camera images are automatically switched for real-time monitoring;

[0037] 4. Cloud servers and local private servers: Use the powerful computing and storage resources of cloud computing service providers to achieve large-scale data processing and storage. Provide high availability and elastic expansion capabilities to adapt to the rapid growth of business. Through a secure network connection, data can be exchanged with exhibition venues in various places. For enterprises or institutions with extremely high data security requirements, you can choose to deploy a local private server. The server is installed in the company's internal computer room, and strict access control and data encryption technology are used to ensure the confidentiality and integrity of the data.

[0038] Communication link and data transmission: Bluetooth communication link is used for short-distance, low-power data transmission. A Bluetooth connection is established between the display prototype and the charger tray, and between the UWB base station and the surrounding Bluetooth devices to achieve fast pairing and data exchange between devices. For example, when the display prototype is placed on the charger tray, the charging requirements and device status information are transmitted through the Bluetooth communication link. The UWB communication link is the core communication method of this system, which is used for high-precision positioning and real-time data transmission. The UWB signal has a nanosecond pulse width and extremely high bandwidth, which can achieve centimeter-level positioning accuracy. Through the UWB communication link, the UWB base station and the UWB tag of the display prototype device can quickly and accurately transmit location information and control instructions. In order to ensure the reliability and stability of data transmission, a custom data transmission protocol is adopted. The protocol includes data packet format, frame structure, checksum and error correction mechanism, etc. During the data transmission process, the data packet is encrypted to prevent the data from being stolen or tampered with.

[0039] System setup and debugging: After the system is installed, initial setup is required. This includes entering the information of the display prototype, setting the parameters of the UWB base station, configuring the user permissions of the IOT management platform, etc. Special configuration tools or web interfaces are used to facilitate operations by management personnel. After the initial setup is completed, on-site debugging is performed. By moving the display prototype, the system's positioning accuracy, alarm response speed, charging stability and other performance indicators are tested. According to the debugging results, the system parameters are optimized and adjusted to ensure that the system reaches the best working state. In order to ensure the long-term stable operation of the system, regular maintenance and calibration are required. Maintenance work includes checking the hardware status of the equipment, cleaning the dust on the surface of the equipment, and updating the software version. The calibration work is mainly aimed at the positioning accuracy of the UWB base station and the charging parameters of the charger tray to ensure that the system performance always meets the design requirements.

[0040] The invention solves the problem that the safety wires, ropes and charging wires connected in the traditional wired anti-theft device are too long and easy to be entangled, and too short to be entangled, thereby improving the customer experience. It is no longer restricted by the two ends being fixed, which is convenient for store display and updating, and does not need to be fixed with glue, thus saving the time of disassembly and assembly, and reducing the risk of damage to the prototype. The wireless anti-theft device enables the display samples to be detachably installed, and can be safely stored when not in business hours, thereby reducing the risk of theft. It can monitor the operation of the display prototypes in real time, analyze the preferences of customers and the product demonstration, and provide valuable data support for store operations. Based on UWB technology, centimeter-level precise positioning can be achieved, and it can accurately determine whether the display prototype exceeds the safe area, and issue an alarm in time to effectively prevent theft. Wireless charging and easy-to-connect parts such as POGOPIN are used to solve the problem of charging wire entanglement, and at the same time adapt to different charging needs to ensure the power supply of the display prototype. Through the IOT management platform, centralized intelligent management of the equipment is realized, and the safe area and early warning mechanism can be flexibly set according to different scenarios, thereby improving the flexibility and accuracy of anti-theft. The advanced UWB wireless display anti-theft technology is used to enhance the sense of science and technology of the product and enhance the image and competitiveness of the store.
