[0013] 1. In this utility model, an intelligent tag is designed. The device utilizes a PCB control motherboard and a display screen to display images. Pressing the start button activates the PCB control motherboard. Images are input to the PCB control motherboard via a connector. The PCB control motherboard displays the images on the display screen in turn according to the program, allowing for continuous image changes. The PCB control motherboard is connected to a mobile device via a Bluetooth positioning module. The Bluetooth positioning module transmits Bluetooth signals, which are received by the mobile device. The mobile device measures the phase of the received Bluetooth signal and calculates the phase difference. The mobile device then uses the calculated... The phase difference is analyzed, and multiple incident angles and complementary angles of the received Bluetooth signal are analyzed. Based on the complementary angles of the incident angles, multiple vertical distances from the Bluetooth positioning module to the mobile device are calculated. Based on these multiple vertical distances, the optimal vertical distance is generated. Based on the optimal vertical distance, the distance from the Bluetooth positioning module to the signal feed point in the mobile device is generated. Based on the generated multiple distances and multiple incident angles, the optimal distance and optimal incident angle are generated, thereby obtaining the relative position of the Bluetooth positioning module and the mobile device. Users can understand the real-time position of the device based on the received information, which solves the problem that existing signs cannot change the displayed images and have poor aesthetics.

[0023] A smart tag includes a front housing 1, a rear housing 2 mounted on the back of the front housing 1, a display screen 3 fixedly connected to the front of the front housing 1, a PCB control motherboard 4 fixedly connected above the center of the front of the rear housing 2, a battery 5 mounted on the front of the rear housing 2 and below the PCB control motherboard 4, a charging contact 6 provided on the back of the rear housing 2 near the battery 5, a start button 7 mounted on the back of the rear housing 2 near the charging contact 6, a buzzer 8 mounted on the front of the rear housing 2 and behind the PCB control motherboard 4, a connector 9 mounted on the outer wall of the front housing 1 above the PCB control motherboard 4, and a Bluetooth positioning module 10 provided on the outer wall of the PCB control motherboard 4.

[0024] Both the front housing 1 and the rear housing 2 are made of ABS plastic. Two sets of charging contacts 6 are provided, connected to the battery 5 via wires. Connector 9 is a 24-pin Zif connector. The start button 7 extends through and out of the rear housing 2. The display screen 3, battery 5, buzzer 8, connector 9, and start button 7 are all electrically connected to the PCB control motherboard 4. Two sets of hanging holes are located above and below the center of the interior of both the front housing 1 and the rear housing 2. Using a hanging rope, the front housing 1 and the rear housing 2 are suspended in a suitable position. Pressing the start button 7 activates the PCB control motherboard 4. Images are input into the PCB control motherboard 4 via connector 9. The PCB control motherboard 4 displays the images on the display screen 3 in turn according to the program, allowing for continuous image changes. The PCB control motherboard 4 is connected to the mobile device via a Bluetooth positioning module 10. The Bluetooth positioning module 10 transmits Bluetooth signals, which the mobile device receives. The phase of the received Bluetooth signal is calculated, and the phase difference of the received Bluetooth signal is calculated. Based on the calculated phase difference, the mobile device analyzes multiple incident angles and complementary angles of the received Bluetooth signal. Based on the complementary angles of the incident angles, multiple vertical distances from the Bluetooth positioning module 10 to the mobile device are calculated. Based on the multiple vertical distances, the mobile device analyzes and generates the optimal vertical distance. Based on the optimal vertical distance, the distance from the Bluetooth positioning module 10 to the signal feed point in the mobile device is analyzed and generated. Based on the generated multiple distances and multiple incident angles, the optimal distance and optimal incident angle are generated, thereby obtaining the relative position of the Bluetooth positioning module 10 and the mobile device. The user can understand the real-time position of the device based on the received information. When the battery 5 has low power, the charger is inserted into the charging contact 6 to charge the battery 5.

[0025] The working process of this utility model is as follows: When the smart tag designed using this solution is in operation, the front shell 1 and the rear shell 2 are suspended in a suitable position using a suspension rope. Pressing the start button 7 activates the PCB control motherboard 4. Images are input into the PCB control motherboard 4 via the connector 9. The PCB control motherboard 4 displays the images on the display screen 3 in turn according to the program, and the displayed images can be continuously changed. The PCB control motherboard 4 is connected to the mobile device via the Bluetooth positioning module 10. The Bluetooth positioning module 10 transmits Bluetooth signals, and the mobile device receives the Bluetooth signals transmitted by the Bluetooth positioning module 10. The mobile device calculates the phase of the received Bluetooth signal and calculates the received Bluetooth signal. Based on the calculated phase difference, the mobile device analyzes multiple incident angles and complementary angles of the received Bluetooth signal. It then calculates and generates multiple vertical distances between the Bluetooth positioning module 10 and the mobile device based on the complementary angles. The mobile device then generates an optimal vertical distance based on these distances. Finally, based on this optimal vertical distance, it generates the distance between the Bluetooth positioning module 10 and the signal feed point in the mobile device. Finally, based on the generated distances and multiple incident angles, it generates an optimal distance and an optimal incident angle, thereby obtaining the relative position of the Bluetooth positioning module 10 and the mobile device. When the battery 5 has low power, the charger is inserted into the charging contact 6 to charge the battery 5.
