[0023] 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.

[0024] 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

[0025] Please see Figure 1-6 This utility model provides a technical solution:

[0026] This utility model provides a multi-functional bus card, including a housing 1. The housing 1 houses a main control module, a bus module, a communication module, a voice module, a positioning module, and a main antenna module. The main control module is fixed to the inner wall of the housing 1, the bus module is located behind the main control module, and the positioning module is located to the side of the main control module. The main control module is connected to the bus module, communication module, voice module, positioning module, and main antenna module. This multi-functional bus card integrates multiple key modules, which work closely together to achieve diverse functions.

[0027] In the embodiments of this application, the main control module is connected to the corresponding interface of each module through specific pins to transmit control signals and data information. Optionally, the main control module is a 4G communication module with a built-in 4G communication module. The main control module performs 4G communication function through the main antenna. The bus card is also equipped with a power supply module, which is powered by a storage battery and supplies power to the entire system through a DC-DC conversion circuit.

[0028] The bus module includes an RF antenna, a digital processing module, a security module, an interface module, a clock module, and a power management module. The bus module's SCK, MOSI, MISO, and CS pins are connected to the SPI interface of the main control module, and its IRQ pin is connected to the GPIO interface of the main control module. Specifically, the SCK (clock signal pin), MOSI (master output / slave input pin), MISO (master input / slave output pin), and CS (chip select pin) pins, connected to the SPI interface of the main control module, form a high-speed synchronous serial communication link. The SPI interface features high speed, full-duplex operation, and synchronization, ensuring fast and stable data transmission between the main control module and the bus module, enabling precise control of the bus module's functions, such as scheduling the bus card transaction process. The IRQ (interrupt request pin) pin is connected to the GPIO interface of the main control module. When events such as transaction completion, successful or failed card authentication occur within the bus module, an interrupt request is sent to the main control module through this pin, and the main control module responds promptly and processes the corresponding transaction.

[0029] The positioning module includes a GNSS positioning chip and a GNSS antenna. The UART_RXD pin of the GNSS positioning chip is connected to the UART_TXD pin of the main control module to establish an asynchronous serial communication channel. The main control module sends commands to the GNSS positioning chip through this channel. After receiving satellite signals and calculating the position information, the GNSS positioning chip transmits the position data to the main control module through this channel. The XTAL pin of the GNSS positioning chip is connected to an external clock to provide a precise clock signal for the GNSS positioning chip, ensuring accurate timing of the internal circuitry and improving positioning accuracy and stability.

[0030] To enable call functionality, the multi-functional bus card of this application also includes a SIM card module. The baseband communication interface pins UART1_TXD and UART1_RXD of the SIM card module are connected to the main control module for data transmission and reception, enabling communication with the main control module and performing operations such as network registration and data transmission. The USIM_CLK, USIM_DATA, and USIM_RST_N pins are connected to the SIM control circuit of the main control module. The main control module uses these pins to initialize, configure parameters, and reset the SIM card module, ensuring its normal interaction with the communication network.

[0031] The voice module includes a microphone module and a speaker module. The microphone module is located on the lower side of the housing 1, and the surface of the housing 1 has a microphone hole 3. The microphone module collects sound signals through the microphone hole 3 on the surface of the housing 1. The speaker module is located on the upper side of the housing 1, and the surface of the housing 1 has a speaker hole 4. The speaker module plays sound through the speaker hole 4. The microphone module and the speaker module are respectively connected to the main control module. The main control module processes the collected sound signals and encodes and converts the voice data to be played to realize the voice call function.

[0032] The housing 1 is also equipped with a button module 2, which is connected to the main control module. When a user presses a button, the button module generates an electrical signal change, which is transmitted to the main control module through a connection line. The main control module identifies the function command corresponding to the button operation according to a preset program. In the embodiment of this application, the button module is located on the front side of the housing 1, and the button module is a quick family number button, which can be directly used to dial a set phone number.

[0033] The main antenna is a flexible FPC antenna that supports 4G LTE Cat.1. The flexible FPC antenna has good flexibility and bendability, and can be flexibly arranged according to the shape of the housing. It can effectively receive and transmit wireless signals, ensure smooth communication between the communication module and the base station, and improve communication quality and stability.

[0034] The radio frequency antenna is a 13.56MHz loop antenna with high sensitivity and anti-interference capability. It conforms to the ISO / IEC 14443 Type A / B standard. When the bus module is close to the bus card reader, the card reader transmits a 13.56MHz radio frequency signal through the antenna. The loop antenna obtains energy through electromagnetic induction to power the chip, eliminating the need to rely on the battery inside the bus card for power, thus ensuring that the bus module is always available.

[0035] The GNSS antenna is a ceramic patch antenna. The ceramic material has a high dielectric constant, which can effectively enhance the ability to capture weak GNSS signals and improve the success rate of positioning.
