[0042] Specifically, the RF transceiver module 121 has a high-precision positioning antenna interface, wherein the high-precision positioning antenna interface includes a single antenna interface and a dual antenna interface, the single antenna interface can be connected to a single antenna via a coaxial cable, the dual antenna interface can be connected to a dual antenna via a coaxial cable, and the single antenna and the dual antenna need to be placed separately and spaced at least 0.8 meters apart from each other to avoid signal interference and errors between the single antenna and the dual antenna. The RF transceiver module 121 also has an FM antenna interface and an AM antenna interface, which can be connected to an FM antenna and an AM antenna via a coaxial cable. The FM antenna and the AM antenna are used to receive wireless broadcast signals, so that the wireless broadcast signals can be processed by the communication device 10, so that the media system on the vehicle can play radio programs.
[0043] In addition, the RF transceiver module 121 also has a digital radio DAB antenna interface, which can be connected to a digital radio DAB antenna via a coaxial cable.

[0046] Reference Figure 2 In some embodiments of the present invention, the communication device 10 may further include a circuit board 12 and a housing 11, a radio frequency transceiver module 121 and an antenna processor 122 are disposed on the circuit board 12, and a plurality of antennas are disposed on the circuit board 12 or on the housing 11; such a configuration may improve the integration of the communication device 10, reduce the cost of the communication device 10, and improve signal quality.
[0047] Specifically, the RF transceiver module 121 and the antenna processor 122 can be integrated on the circuit board 12 to reduce the wiring harness length between the RF transceiver module 121 and the antenna processor 122 and improve transmission efficiency; high-precision positioning antennas, FM antennas, AM antennas, digital radio DAB antennas, global positioning GPS antennas, V2X vehicle networking antennas, 5G antennas, 4G antennas, wireless network WIFI antennas and Bluetooth BT antennas can be made into on-board antennas, that is, a variety of antennas can be directly set on the circuit board 12 to improve the integration of the communication device 10, and compared with the related art of setting the antenna outside the communication device 10, the embodiment of the present invention reduces the processor module housing 11 and reduces the cost. In addition, by integrating the antenna on the circuit board 12, the number of coaxial cables between the antenna and the antenna processor 122 can be reduced, and the length of the coaxial cable can be reduced, thereby improving the quality of the signal.
[0048] In addition, multiple antennas can be set in the housing 11, which can improve the integration of the communication device 10 and reduce the distance between the multiple antennas and the RF transceiver module 121, thereby reducing the number of coaxial cables and reducing the length of the coaxial cables, thereby improving the signal quality.
[0049] Reference Figure 1 In some embodiments of the present invention, the multiple antenna interfaces also include at least one reserved antenna interface; specifically, since the multiple antennas are received or sent to the antenna processor 122 through the RF transceiver module 121, the RF transceiver module 121 can have at least one reserved antenna interface, which is convenient for adding new functions to the communication device 10 and improving the applicability of the communication device 10.
[0050] Reference Figure 1 In some embodiments of the present invention, the RF transceiver module 121 has at least one communication interface connected to the antenna processor 122, and the communication interface is a serial interface or a parallel interface; optionally, the RF transceiver module 121 has a serial interface, and the antenna processor 122 is connected to the RF transceiver module 121 through the serial interface, so that the RF transceiver module 121 and the antenna processor 122 can be connected through fewer wire harnesses, which simplifies the layout of the communication device 10, reduces the cost of the wire harness, and reduces the signal interference between the wire harnesses. Optionally, the RF transceiver module 121 has a parallel interface, and the antenna processor 122 is connected to the RF transceiver module 121 through the serial interface, so that multiple data bits can be transmitted simultaneously, providing higher data transmission efficiency, thereby improving the working efficiency of the communication device 10.
[0051] Reference Figure 1In some embodiments of the present invention, the antenna processor 122 has at least one memory interface for connecting to the external memory 13; this configuration can ensure that the antenna processor 122 has sufficient bandwidth for caching or storage, thereby improving the working efficiency of the communication device 10. For example, the memory interface can be an MCP interface for connecting to an external MCP memory (i.e., Multiple Chip Package).
[0052] In some embodiments of the present invention, the antenna processor 122 is configured to meet the V2X signal processing capability; specifically, in combination with the aforementioned embodiments, the multiple antennas may include a vehicle networking V2X antenna, and the multiple antenna interfaces may include a vehicle networking V2X antenna interface. The vehicle networking V2X antenna is connected to the vehicle networking V2X antenna interface of the RF transceiver module 121 via a coaxial cable; when the communication device 10 is working, the RF transceiver module 121 can receive and send wireless signals through the vehicle networking V2X antenna, and the RF transceiver module 121 communicates with the wireless processor. The wireless processor is configured to meet the V2X signal processing capability and can process the data sent to the wireless processor by the RF transceiver module 121. Compared with the related art where the computing power of the processor is insufficient and an additional V2X computing power expansion module needs to be arranged, the embodiments of the present invention can improve the integration of the communication device 10, reduce the layout length of the wiring harness in the communication device 10, and improve the signal quality.
[0053] Reference Figure 1 In some embodiments of the present invention, the antenna processor 122 may have a photoelectric conversion interface, and the antenna processor 122 is configured to communicate with the external device 20 through the photoelectric conversion interface; such a setting can improve the transmission efficiency between the antenna processor 122 and the external device 20 and reduce the layout length of the wiring harness.
[0054] In the related art, the antenna processor 122 has a USB interface, a CAN interface, etc., and the antenna processor 122 can transmit data with the external device 20 through these interfaces. However, although the USB interface has a high transmission rate, it does not meet the long-distance unlimited requirements of the vehicle, and the CAN interface has a low transmission rate and does not meet the large data transmission of the communication device 10; therefore, in the embodiment of the present invention, the antenna processor 122 may have an optical-electric conversion interface, wherein the optical-electric conversion interface may be an optical fiber transceiver or an optical-electric conversion module. In other words, the optical-electric conversion interface of the antenna processor 122 may be connected to the external device 20 through an optical fiber, so that the data transmission efficiency and data transmission volume between the antenna processor 122 and the external device 20 can be improved. In combination with the above, when the USB interface is used, the antenna processor 122 needs to be arranged close to the external device 20; while in the embodiment of the present invention, the optical-electric conversion interface facilitates the connection between the antenna processor 122 and the external device 20, and the antenna processor 122 does not need to be arranged close to the antenna, thereby improving the arrangement flexibility of the communication device 10.
[0055] Reference Figure 1 In some embodiments of the present invention, the antenna processor 122 is integrated with an inertial measurement unit (i.e., the IMU in the accompanying drawings), and the antenna processor 122 is configured to receive data collected by the inertial measurement unit and process the data; in this way, the measurement of three-axis attitude angle (or angular velocity) and acceleration can be achieved through the antenna processor 122, and there is no need to add an inertial measurement unit outside the antenna processor 122, thereby improving the integration of the communication device 10 and reducing the volume of the communication device 10.
[0056] In detail, in the related art, since the communication device 10 adopts mobile phone chips such as 5G baseband chips, it is unable to realize the function of an inertial measurement unit. Therefore, in an embodiment of the present invention, the inertial measurement unit can be integrated into the antenna processor 122. In this way, the antenna processor 122 can realize the function of the inertial measurement unit, that is, measure the three-axis attitude angle (or angular velocity) and acceleration of the vehicle, thereby improving the integration of the communication device 10 and reducing the volume of the communication device 10.
[0057] Reference Figure 1 In some embodiments of the present invention, the antenna processor 122 is integrated with a power management unit (i.e., PMIC in the figure), and the power management unit is configured to supply power to the antenna processor 122; in detail, the power management unit may be responsible for managing and distributing power to various parts of the antenna processor 122 to assist the antenna processor 122 in better realizing data processing; in this way, the integration of the communication device 10 can be improved and the size of the communication device 10 can be reduced.
[0058] Reference Figure 1 In some embodiments of the present invention, the antenna processor 122 has at least one of a GPIO interface, an I2C interface, an SPI interface, and a USB interface, which is used to externally connect a device that communicates with the power management unit of the RF transceiver module 121 and / or the antenna processor 122; optionally, the antenna processor 122 has a GPIO interface, an I2C interface, an SPI interface, and a USB interface. Through these interfaces, technicians can communicate with the power management unit of the RF transceiver module 121 and / or the antenna processor 122 through the antenna processor 122, which facilitates the technicians to perform fault detection, remote control, monitoring, data exchange, diagnosis, and update operations on the power management unit of the RF transceiver module 121 and / or the antenna processor 122, thereby improving the working stability of the communication device 10.
[0059] It needs to be explained that GPIO stands for General Purpose Input / Output, which is an electronic interface that allows a microcontroller or computer to input and output digital signals with external devices. The GPIO interface is usually used to control and monitor various sensors, switches, LEDs, etc.
[0060] I2C stands for Inter-Integrated Circuit. It is a multi-master, serial computer bus that allows multiple "slave devices" to communicate with one "master device". The I2C interface is commonly used for low-speed peripherals such as temperature sensors, real-time clocks, etc.
[0061] SPI stands for Serial Peripheral Interface, which is a high-speed, full-duplex, synchronous serial I / O interface, commonly used to connect the Central Processing Unit (CPU) and various peripheral devices such as SD cards, Digital Signal Processors (DSPs), etc.
[0062] USB stands for Universal Serial Bus, which is a widely used interface technology for connecting computers with external devices. The USB interface supports plug-and-play and hot-swap, and can transmit data and power. There are multiple standards for USB interfaces, such as USB 1.1, USB 2.0, USB 3.0, etc. Each standard has a different data transfer rate.
[0063] Reference Figure 1 In some embodiments of the present invention, the antenna processor 122 also has a UART interface for debugging the antenna processor 122 and printing data; specifically, the UART interface can be used for debugging the antenna processor 122, wherein, when the antenna processor 122 is in the development and debugging stage, the technician can monitor the behavior of the antenna processor 122 through the UART interface, read the error log, or update the algorithm in the antenna processor 122; of course, the data in the antenna processor 122 can also be printed through the UART interface, so as to facilitate the analysis of the antenna processor 122.
[0064] It needs to be explained that UART is the abbreviation of Universal Asynchronous Receiver / Transmitter, which is a full-duplex, asynchronous communication interface that works at the data link layer and supports standard circuits such as RS232 and RS485.
[0065] Reference Figures 1 to 3According to the communication device 100 in the embodiment of the present invention, the communication device 100 includes the communication device 10 and the central computing processing unit in the above embodiment, and the central computing processing unit communicates with the antenna processor 122. By applying the aforementioned communication device 10, the cost of the communication device 100 can be reduced and the signal quality can be improved.
[0066] Specifically, the antenna processor 122 can integrate multiple external processor modules and communicate with the RF transceiver module 121, and use the RF transceiver module 121 to transmit and receive wireless signals; when receiving wireless signals, multiple antennas are connected to the RF transceiver module 121 through multiple antenna interfaces to transmit wireless signal data to the RF transceiver module 121, and after the RF transceiver module 121 processes the data, it transmits the data to the antenna processor 122, and the antenna processor 122 processes the received multiple data and sends it to the external device 20; when sending wireless signals, the external device can transmit the data to the antenna processor 122, and after the antenna processor 122 processes it, it sends it to the RF transceiver module 121, and the RF transceiver module 121 can send the data in the form of wireless signals through multiple antennas. Compared with the related art, in which multiple additional processor modules are connected to the antenna processor 122, the present invention can reduce the cost of the communication device 100.
[0067] Among them, the RF transceiver module 121 has multiple antenna interfaces, and the multiple antenna interfaces may include a high-precision positioning antenna interface, an FM&AM antenna interface, a DAB antenna interface, a GPS antenna interface, a V2X antenna interface, a 5G antenna interface, a 4G antenna interface and a WIFI&BT antenna interface. These interfaces can be used to connect with multiple antennas, so that the RF transceiver module 121 receives multiple wireless signals and transmits the data to the antenna processor 122 for processing; for example, the FM&AM antenna interface can be connected to the FM&AM antenna, so that the RF transceiver module 121 can transmit the received wireless broadcast signal to the antenna processor 122 for data processing, and then the antenna processor 122 can transmit the processed data to the broadcaster inside the vehicle for playback; for another example, the 5G antenna interface can be connected to the 5G antenna, so that the RF transceiver module 121 can transmit the received 5G signal to the antenna processor 122 for data processing, and then the antenna processor 122 can transmit the processed data to the equipment inside the vehicle, so that the equipment inside the vehicle can perform 5G communication.
[0068] Furthermore, the communication device 10 also includes a circuit board 12 and a housing 11, and the RF transceiver module 121 and the antenna processor 122 can be integrated on the circuit board 12, thereby reducing the wiring harness length between the RF transceiver module 121 and the antenna processor 122, and improving the transmission efficiency; and the aforementioned high-precision positioning antenna, FM&AM antenna, DAB antenna, GPS antenna, V2X antenna, 5G antenna, 4G antenna and WIFI&BT antenna can be manufactured as an on-board antenna, that is, multiple antennas are integrated on the circuit board 12, thereby reducing the coaxial harness length between the RF transceiver module 121 and the multiple antennas, and improving the signal quality and integration of the communication device 10. Of course, multiple antennas can be set on the housing 11, which can also improve the integration of the communication device 10, reduce the distance between the multiple antennas and the RF transceiver module 121, thereby reducing the number of coaxial cables, and reducing the layout length of the coaxial cables, thereby improving the signal quality.
[0069] In addition, the RF transceiver module 121 also reserves at least one antenna interface, which facilitates the RF transceiver module 121 to connect a new antenna and add new functions to the communication device 10. The antenna processor 122 has at least one memory interface for connecting to the external memory 13, which can provide the antenna processor 122 with sufficient bandwidth for caching or storage, thereby improving the working efficiency of the communication device 10.
[0070] In addition, the antenna processor 122 may have the ability to meet the V2X signal processing requirements, thereby adding an additional V2X expansion computing module to the antenna processor 122, thereby improving the integration of the communication device 10 and reducing the volume of the communication device 10. The antenna processor 122 is integrated with an inertial measurement unit. In other words, the three-axis attitude angle (or angular velocity) and acceleration of the vehicle can be measured through the antenna processor 122. In addition, the antenna processor 122 is also integrated with a power management unit, which is used to power the antenna processor 122, thereby improving the integration of the antenna processor 122.
[0071] Reference Figures 1 to 3 In some embodiments of the present invention, the central computing unit communicates with the antenna processor 122 via optical fiber; specifically, in combination with the above embodiments, the antenna processor 122 has an optical-to-electrical conversion interface, and the optical fiber can be connected to the optical-to-electrical conversion interface and connected to the central computing unit to increase the data transmission volume between the central computing unit and the antenna processor 122, as well as the output transmission speed, and improve the working stability of the communication device 100. Among them, the central computing unit is used to process the data received from the antenna processor 122, or send data to the antenna processor 122, so as to realize the management of the vehicle communication system, provide support for the vehicle navigation system, and provide support for the intelligent driving of the vehicle.

The single antenna is used to receive satellite signals and perform basic positioning of the vehicle. The dual antenna can improve higher positioning accuracy and directional capability.
[0074] Of course, through the communication device 10 or the communication equipment 100, the vehicle can receive wireless broadcast signals so that the radio in the vehicle can play FM & AM radio stations.
[0075] In addition, refer to Figure 1 , Dram (ie, internal memory) and Flash (ie, flash memory) are memories on the antenna processor 122; these memories can be connected to the external memory 13 to improve the working efficiency of the antenna processor 122.
