Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0029] Please see Figure 1-8 This utility model provides a technical solution:

[0030] like Figure 1As shown, this utility model provides an electronic work badge with card opening and identity reading functions, including a housing 10. The housing houses a main control module 20, a work badge module 21, a card opening module 22, an identity reading module 23, and a communication module 24. The main control module 20 is connected to the work badge module 21, the card opening module 22, the identity reading module 23, and the communication module 24, respectively. The communication module 24 communicates via a main antenna. This application integrates the card opening and identity reading modules into a portable electronic work badge. The main control module connects to the corresponding interfaces of each module through specific pins to transmit control signals and data information, and transmits data through the communication module. This centralizes and lightweights the business processing equipment, effectively simplifying the processing procedures when providing services outside the office or across regions, improving work efficiency and user satisfaction.

[0031] Furthermore, such as Figure 2 As shown, the work badge module 21 includes a CPU card chip, and the identity reading module 23 includes an RF card reader chip. The CPU card chip and the RF card reader chip are switched and connected to the RF antenna circuit via an RF switch 25.

[0032] In the embodiments of this application, the main control module 20 may be a low-power, high-performance MCU chip. The main control module 20 can provide multiple interfaces such as UART, SPI, I²S, and GPIO to meet the connection requirements of each module. The communication module 24 is a 4G module and also includes a power supply module 28. The power supply module 28 includes a lithium battery and a charging management circuit. The power supply module 28 is connected to the main control module 20 to provide power to each module.

[0033] like Figure 5-6 As shown, the CPU card chip can be the Mifare DESFire EV2 chip, which supports dynamic key management and two-way authentication, effectively preventing data tampering. The SCK, MOSI, MISO, and CS pins of the CPU card chip are connected to the SPI interface of the main control module 20, and the IRQ pin is connected to the GPIO interface of the main control module 20. The SCK, MOSI, MISO, and CS pins, connected to the SPI interface of the main control module 20, form a high-speed synchronous serial communication link. The IRQ pin, connected to the GPIO interface of the main control module 20, sends an interrupt request to the main control module 20 through this pin when events such as transaction completion, successful or failed ID card recognition occur within the ID card module. The main control module 20 responds promptly and processes the corresponding transaction.

[0034] like Figure 7As shown, the radio frequency card reader chip can use the YCL5018 chip. The TVDD pin of the radio frequency card reader chip provides power to the radio frequency section, the YC5018_3V3 pin provides power to the chip core, the SCK pin is the clock signal pin, the RX pin is the radio frequency signal receiving pin, the filtered and shaped signal is input into the chip to complete the signal processing, and the TX1 and TX2 pins are radio frequency signal output pins.

[0035] The RF switch 25 allows for switching between the CPU card chip in the ID card module 21 and the RF card reader chip in the identity reading module 23, enabling the use of the same RF antenna circuit. This achieves functional reuse, reduces hardware costs, and avoids interference from multiple antennas. During the switching process, the RF switch 25 ensures that the two modules do not use the antenna circuit simultaneously, preventing mutual interference and guaranteeing communication reliability.

[0036] The radio frequency antenna circuit includes an antenna coil, a resonant capacitor, and a filter circuit, wherein the antenna coil and the resonant capacitor form an LC resonant circuit.

[0037] In the embodiments of this application, the antenna coil can be a PCB printed coil or a wire-wound coil. The resonant capacitor is used to adjust the impedance of the antenna circuit to match the output impedance of the RF chip, reducing reflection loss. The filter circuit is used to suppress interference signals and improve the quality of RF communication. For example, the antenna coil is wound with 50 turns of 0.1mm diameter enameled wire, the resonant capacitor is selected as 60pF, and the filter circuit uses an LC filter network. When the ID card is close to the card reader, energy is coupled between the antenna coil and the 13.56MHz RF signal emitted by the card reader to obtain energy to power the chip. The ID card module does not need to rely on the battery inside the electronic ID card for power, ensuring that the ID card module is always available.

[0038] Furthermore, the card opening module 22 includes a 7816 card opening chip and a card opening slot 11. The 7816 card opening chip is connected to the main control module 20 via a serial port. The card opening slot 11 is located on the rear side of the housing 10, and a connection contact point is provided in the card opening slot 11.

[0039] In the embodiments of this application, after the staff inserts the unactivated SIM card into the card slot 11, the insertion detection pin CARDDET of the card activation module 22 sends a level signal to the main control module 20. The main control module 20 communicates with the card activation module 22 through the 7816 controller connected to the main control module 20 via a serial port, and completes the card activation operations such as SIM card initialization and data writing according to the card activation protocol, thereby realizing the integration of the card activation function and facilitating mobile business processing.

[0040] Furthermore, it also includes a positioning module 26, which includes a GNSS chip and a GNSS antenna. The GNSS chip is connected to the main control module 20 via a serial port.

[0041] In the embodiments of this application, the GNSS chip is an integrated GPS / BeiDou dual-mode positioning chip. The positioning module 26 transmits the positioning data to the main control module 20 through the UART interface. The main control module then encrypts the data and uploads it to the designated platform via the CAT1 network to realize the positioning of personnel.

[0042] Furthermore, the main antenna is a flexible FPC antenna, and the GNSS antenna is a ceramic patch antenna.

[0043] The main antenna is a flexible FPC antenna that supports 4G LTE Cat.1. The flexible FPC antenna has excellent flexibility and bendability, allowing for flexible arrangement according to the housing shape, effectively receiving and transmitting wireless signals, ensuring smooth communication between the communication module and the base station, and improving communication quality and stability. The GNSS antenna is a ceramic patch antenna. The ceramic material has a high dielectric constant, which effectively enhances the ability to capture weak GNSS signals and improves the success rate of positioning.

[0044] Furthermore, the system also includes a call module 27, which comprises a SIM card module, a microphone module 12, and a speaker module 13. The SIM card module is connected to the main control module 20 via a UART interface, and the microphone and speaker modules are connected to the main control module 20 via an I²S interface. The SIM card module communicates with the main control module 20 via UART pins, with its USIM_CLK, USIM_DATA, and USIM_RST_N pins connected to the SIM control pins of the main control module 20. The UART interface is simple to use and has a suitable transmission distance, meeting the data transmission needs between the SIM card module and the main control module 20 and enabling communication. The I²S interface is specifically designed for audio data transmission, providing a high-speed, low-latency data transmission channel to ensure high-quality audio signal transmission, thereby achieving clear voice call functionality.

[0045] Furthermore, such as Figure 3 As shown, the microphone module 12 is located below the front side of the housing 10, and the speaker module 13 is located above the front side of the housing 10. The microphone module 12 collects sound signals through a microphone hole on the surface of the housing 10; the speaker module 13 plays sound through a speaker hole on the surface of the housing 10.

[0046] Furthermore, a button module 14 is provided on the front side of the housing, and the button module 14 is connected to the main control module 20. When the user presses a button, the button module generates an electrical signal change, which is transmitted to the main control module through the connection line. The main control module identifies the function command corresponding to the button operation according to a preset program.

[0047] Furthermore, such as Figure 4As shown, an identity reading identification area 15 is provided on the rear side of the housing 10. The identity reading identification area 15 is equipped with a conspicuous graphic mark to guide the user to correctly place the card or bring it close to the reading device, thereby improving the convenience and accuracy of identity reading operations.
