[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0028] Reference Figure 1 、 Figure 2 and Figure 3 , shows a schematic structural diagram of an electronic tag of the present invention, which may specifically include: a WiFi receiving module 100, a control board 200, a key module 300, a storage module 400, an electronic ink screen 500, and a housing 600; the WiFi receiving module 100 is electrically connected to the control board 200; the key module 300 is electrically connected to the control board 200 and is used to wake up the control board 200 by the trigger state of the key module 300. It should be noted that by pressing the key module 300, the key module 300 obtains an electrical signal and transmits it to the control board 200, causing the control board 200 to start working. It can receive the WiFi signal through the WiFi receiving module 100, thereby entering the configuration mode, accessing the website, and then configuring the information to be displayed according to actual needs. After the configuration is completed, the electronic tag automatically exits the configuration mode. If the screen needs to be changed, the above steps need to be repeated.

[0029] Furthermore, the control board 200 is electrically connected to the storage module 400, forming a channel for retrieving and storing data. It should be noted that the storage module 400 has already stored certain data. The control board 200 receives the WiFi signal through the WiFi receiving module 100 and connects to the website for configuration. After the website is configured, it sends a new configuration signal. This new signal is sensed by the WiFi receiving module 100 via WiFi and is then received by the control board 200. This signal corresponds to the data in the storage module 400. The control board 200 retrieves the data from the storage module 400 and transmits it to the electronic ink screen 500.

[0030] Furthermore, the electronic ink screen 500 is electrically connected to the control board 200 for displaying label information. The electronic ink screen 500 is embedded in the housing 600, and the key module 300 is disposed on the surface of the housing 600. The WiFi receiver module 100, the control board 200, and the storage module 400 are arranged in preset positions within the housing 600. After the WiFi receiver module 100 receives the configuration signal from the WiFi signal, the control board 200 retrieves the data from the storage module 400 and transmits it to the electronic ink screen 500 for display. It should be noted that when the key module 300 is pressed, it first wakes up the control board 200, causing it to begin operation. Then, upon receiving another electrical signal from the key module 300, the control board 200 controls the electronic ink screen 500 to reset itself, clearing the data already displayed on the electronic ink screen 500.

[0031] To further explain, the control panel 200 only begins operating when the key module 300 sends a signal, accessing the WiFi signal through the WiFi receiving module 100. The tag data is then modified on a pre-set website. Once configuration is complete, the E-Ink screen 500 displays information and the control panel 200 stops operating. At this point, due to the characteristics of the E-Ink screen 500: it only consumes power when pixel colors change (for example, from black to white), and the image on the display remains after power is disconnected, thus saving a lot of energy. The electronic paper, combined with the storage chip, can hold an entire library, so the image can be retained even after the control panel 200 stops operating. The control panel 200 consumes no power when not in operation, and the E-Ink screen 500 also consumes no power, which can significantly save electricity and energy.

[0032] Further, refer to Figure 4 The WiFi receiving module 100 includes an antenna (not shown) and a radio frequency connector; one end of the antenna is electrically connected to one end of the radio frequency connector, and the other end of the radio frequency connector is electrically connected to the control board 200. It should be noted that the antenna is used to receive WiFi signals. One end of the radio frequency connector is connected to the antenna, and the other end is connected to the ANT pin on the control board via the wire. This converts the WiFi signal from a wireless signal into an electrical signal and transmits it to the control board, so that the control board 200 can access the data in the storage module 400 and display it on the electronic ink screen 500.

[0033] Furthermore, the loop is also provided with a number of filter capacitors, coupling inductors, and coupling capacitors. It should be noted that the function of the filter capacitor is to filter out the AC component in the power rectifier circuit. This makes the output DC smoother, and for precision circuits, a combination of parallel capacitor circuits is used to improve the working effect of the filter capacitor. The filter capacitor of the loop can make the electrical signal converted by the WiFi signal more stable. The coupling capacitor is to make the working point of the latter stage unaffected by the previous stage, so it is necessary to separate the previous stage and the latter stage in terms of DC. At the same time, it can also enable the AC signal to be smoothly transmitted from the previous stage to the latter stage. The method that can accomplish this task at the same time is to use capacitor transmission or transformer transmission to achieve it. They can both transmit AC signals and cut off DC, so that the working points of the front and rear stages are not involved with each other. However, the difference is that when using capacitor transmission, the phase of the signal is delayed a little, and when using transformer transmission, the high-frequency component of the signal is lost a little. Therefore, it is more preferred to use coupling capacitors.

[0034] Furthermore, the RF connector is the RF-001IPEX. It should be noted that this type of connector has excellent transmission performance at high frequencies, ensuring stable transmission of RF signals and is suitable for applications requiring high-frequency data transmission. It also offers good contact performance and a stable connection, ensuring stable and reliable signal transmission. This is particularly beneficial for stable signal transmission in the electronic tag application scenario.

[0035] Combine Figure 5 The control board 200 includes a main control chip, and the model of the main control chip is preferably DA16200-00000A32 QFN48_6X6. It should be noted that the QFN48_6X6 package of the control board adopts a smaller size design, which makes it very suitable for space-constrained applications and helps to design more compact circuit boards to meet the small size requirements of the electronic tag. Secondly, the QFN (Quad Flat No-leads Package) package usually has a ground pin directly connected to the PCB (Printed Circuit Board), which helps to dissipate heat and reduce the operating temperature of the chip, improving overall performance and reliability, making the electronic tag more stable and lasting longer. The QFN package's short-distance pin layout helps to reduce resistance and inductance, improving the performance and signal integrity of high-frequency circuits. Finally, due to the relatively simple manufacturing process of the QFN package, it usually has a lower cost, which helps to reduce the manufacturing cost of the overall product. Considering the above, it is more preferred to use DA16200-00000A32 QFN48_6X6.

[0036] Combine Figure 6, further stating that the electronic tag also includes a screen drive circuit; the screen drive circuit is electrically connected to the electronic ink screen 500 and the control board 200, respectively. It should be noted that the screen drive circuit is electrically connected to the electronic ink screen 500 to drive the electronic ink screen 500 to change the displayed content. Furthermore, through the electrical connection between the screen drive circuit and the control board 200, the control board 200 issues instructions to the screen drive circuit, which then retrieves data from the storage module 400 and transmits it to the screen drive circuit for further display on the electronic ink screen 500. Furthermore, the control board 200 receives the WiFi signal of the modification instruction, reads the data from the storage module 400, retrieves the data, processes it according to the instruction, and then transmits it to the screen drive circuit for display on the electronic ink screen 500.

[0037] Further, combined Figure 7 and Figure 8 , further stating that the electronic tag also includes a power supply module; the power supply module consists of a discharge circuit and a charging circuit; the power supply module consists of a discharge circuit, a battery, and a charging circuit; the battery is electrically connected to the discharge circuit and the charging circuit, respectively. It should be noted that the charging circuit can be a wireless charging module or a USB charging circuit. The USB Type-C interface has become a standard interface for many new devices, including laptops, smartphones, and tablets. This allows users to enjoy wider compatibility and interoperability, enabling multiple devices to be shared with one cable, eliminating the need for multiple cables, which is more convenient. Furthermore, the USB Type-C connector is smaller than traditional USB connectors, making it suitable for thin and lightweight device designs, facilitating a more compact device design that meets the usage scenarios of the electronic tag. Therefore, based on comprehensive considerations, the USB Type-C charging circuit is preferred. It should be noted that the charging circuit charges the battery, fully charging it, and then the battery discharges the battery in the discharge circuit to complete the power supply.

[0038] Furthermore, the discharge circuit is electrically connected to the control board 200 and the electronic ink screen 500 for power supply. It should be noted that when the key module 300 is pressed, the control board 200 connects the circuit and enters configuration mode, at which point the discharge circuit discharges. After configuration is complete, the screen drive circuit drives the electronic ink screen 500 to display preset information. Configuration mode then ends, the control board 200 disconnects the circuit, and the discharge circuit stops discharging. Due to the material properties of the electronic ink screen 500, power is consumed only when graphic information needs to be changed. Therefore, after configuration is complete, the electronic tag consumes no power. Furthermore, the battery is a 3000mAh polymer lithium battery. Based on the power consumption required for one configuration, a full charge can achieve 360 content changes, resulting in low power consumption and a long lifespan.

[0039] Further, combined Figure 9 The key module 300 includes a registration key and a reset key; the registration key and the reset key are electrically connected to the control board 200 respectively; the registration key and the reset key are arranged on the surface of the housing 600 at a preset position. It should be noted that one end of the reset key is grounded, and the other end is connected to the KEY_PWR_RST pin of the control board 200, and then grounded to form a reset circuit. When the reset key is not pressed, the reset circuit is not conductive. When the reset key is pressed, an electrical signal is generated, so that the control board 200 issues a reset instruction to the electronic ink screen 500; one end of the registration key is grounded, and the other end is connected to the KEY_WAKE_UP__GPIOA9 pin and the power signal of VDD3V_WIFI respectively, and then grounded to form a registration circuit. When the registration key is not pressed, the circuit connected to the control board 200 in the circuit is not conductive. When the registration key is pressed, the circuit is conductive and the control board 200 starts working. It should be added that the reset button can be a micro switch, including but not limited to a micro switch, which can be reset after the force is removed. The registration button also leads to a circuit connected to the control board 200. When the configured WiFi signal is obtained, the signal resets the registration button, thereby powering off the control board 200 and making it stop working. If the screen content needs to be changed, manually press the registration button and the reset button to change it.

[0040] Further, combined Figure 10, the electronic tag also includes an LED light module; the power supply module is electrically connected to the LED light module. It should be noted that the LED light module has three-color lights: red, yellow, and blue. Each light represents the following: the blue light flashes slowly (once every 500ms), the tag enters the configuration mode; the blue light flashes quickly (once every 100ms), the WIFI-TOOL tool is connected to the tag; the blue light flashes very quickly (once every 50ms), the parameters are set successfully, and the tag is about to restart; the red light flashes at intervals, indicating that the tag is not connected to the WiFi router. After plugging in the USB, the green light turns on and charging begins. Unplug the USB and the green light goes out.

[0041] Furthermore, the housing 600 is preferably a rectangular parallelepiped, with the electronic ink screen 500 mounted on one side of the housing 600, along with the registration button. A hole for a reset button is located on the other side, and a lanyard is located on the side of the housing 600 not housing the electronic ink screen 500, for easy portability. Furthermore, the charging circuit includes a USB charging port located on a side of the housing 600. A slot is also located on the other side of the housing 600, into which the battery is removably mounted.

[0042] Furthermore, when changing the content of the electronic ink screen 500, you need to first press the registration button, keep pressing the registration button without releasing it, and then push the small hole on the back of the label (reset button). At this time, the green light is always on. After about 5 seconds, the green light flashes. At this time, you can release the registration button. At this time, the blue light starts to flash slowly, indicating that the system has entered the configuration mode; then select the content information to be displayed on the configuration website. After the selection is made, the configuration is completed. After the parameters are configured, the label automatically exits the configuration mode and enters the normal mode. At this time, the control board 200 stops working and the power supply module does not supply power.

[0043] Finally, it should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or terminal device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or terminal device.
