Further, the antenna assembly 11 communicates with the outside by using 3G/4G/5G wide area network wireless communication, but in other embodiments, the antenna assembly 11 may also communicate with the outside by using V2X, WiFi/LWAN local area network wireless communication, BT/BLE, NFC, infrared or LiFi short-range wireless communication, WiFi/BT/UWB indoor positioning communication, GNSS, GPS, compass, GLONASS satellite positioning communication, FM/AM, DAB, SDARS broadcast, and digital broadcast communication.
Further, the novel integrated smart antenna further comprises one or more communication components 12, wherein the communication components 12 are used for communicating with one or more ECUs in a vehicle, the communication components 12 in the present invention are communication units capable of being connected with an antenna and transmitting signals received by the antenna to the inside of the vehicle, the communication units may be a port, a communication module, or a data connection line, in the prior art, the communication components 12 often communicate with one or more ECUs in the vehicle through a wireless short-range communication module, but in the present invention, the communication components 12 and the antenna components 11 are integrated, that is, the communication components 12 and the antenna components 11 as a whole communicate with one or more ECUs.
Further, the new integrated smart antenna further includes a main processor 13, which is in communication with the antenna component 11 and the communication component 12, respectively, the main processor includes but is not limited to a main MCU, which is a micro control unit, also called a single-chip microcomputer or a single-chip microcomputer, the frequency and specification of the central processor are reduced appropriately, and peripheral interfaces such as a memory, a counter, a USB, a/D conversion, UART, PLC, DMA and the like, and even an LCD driving circuit are integrated on a single chip to form a chip-level computer, which is controlled in different combinations for different application occasions. Such as mobile phone, PC periphery, remote controller, control of stepping motor, robot arm, etc. in automobile electronics, industry, etc., the MCU can be seen in the figure, and in the present invention, the main processor is respectively communicated with the antenna unit 11 and the communication unit 12, that is, the main processor 13 controls the data transmission, receiving and transmitting of the antenna unit 11 and the communication unit 12.
Furthermore, the communication component communicates with the ECU by adopting a CAN protocol, namely a controller area network bus, which is a serial communication protocol bus for real-time application, CAN transmit signals by using a twisted pair, and is one of the most widely applied field buses in the world. The CAN protocol is used for communication between various components in an automobile, thereby replacing expensive and bulky wiring harnesses. The robustness of the protocol extends its use to other automation and industrial applications. The features of the CAN protocol include serial data communication for integrity, real-time support, transmission rates up to 1Mb/s, and 11-bit addressing and error detection capabilities, while in other embodiments the communication components communicate with the ECU using an ethernet bus protocol, in which ethernet is currently the most widely used local area network technology. Due to its simplicity, low cost, high scalability, and good integration with IP networks, the application of ethernet technology is advancing from intranets to the field of public telecommunication networks. The ethernet access is a combination of ethernet technology and integrated wiring, and is used as an access network of a public telecommunication network to directly provide a transmission channel of multiple services based on IP for users. The essence of ethernet technology is a two-layer medium access control technology, which can be transmitted over a five-wire line, or combined with other access media to form a variety of broadband access technologies. The Ethernet is combined with VDSL on a telephone copper cable to form an EoVDSL technology; in combination with a passive optical network, an EPON technique is generated; in a wireless environment, WLAN technology is developed
Further, the communication component 12 communicates with the ECU21 by using CAN-FD protocol, and in the field of automobiles, as the requirement for bandwidth of data transmission increases, the traditional CAN bus is difficult to meet the increased requirement due to the limitation of bandwidth. In addition, the BOSCH company introduced CAN FD in order to reduce the bandwidth gap between CAN networks (max.1MBit/s) and FlexRay networks (max.10MBit/s). CAN FD (CAN with Flexible Data rate) inherits the main characteristics of CAN bus. The CAN bus adopts a two-wire serial communication protocol, is based on a non-destructive arbitration technology, is distributed in real-time control, and has high safety due to a reliable error processing and detecting mechanism, but the bandwidth and the data field length of the CAN bus are limited. The CAN FD bus makes up the restrictions of the CAN bus bandwidth and the data field length, and the CAN FD bus is mainly different from the CAN bus in the following two aspects: variable rate CAN FD uses two bit rates: the variable rate is from the BRS bit in the control field to before the ACK field (including the CRC delimiter) and the rest is the rate used by the original CAN bus. The two rates are respectively provided with a set of bit time definition registers, the bit time definition registers CAN adopt different bit time units TQ and also have different distribution proportions of each section of bit time, the length of a data field is greatly expanded by the new data field length CAN FD, the DLC supports 64 bytes at most, the DLC is the same as the original CAN bus when the DLC is less than or equal to 8, and has a nonlinear increase when the DLC is greater than 8, so the maximum data field length CAN reach 64 bytes.
Further, the communication part 12 communicates with the ECU using an LIN protocol, and the LIN (local interconnect network) bus is a low-cost serial communication protocol based on UART/SCI (universal asynchronous receiver/serial interface). The low-end communication, which aims at the nodes of the vehicle body network module, is mainly used for the serial communication of intelligent sensors and actuators, which is the part which is not required by the bandwidth and the function of a CAN bus. The communication component can also adopt a FlexRay protocol to communicate with the ECU, the FlexRay vehicle-mounted network standard becomes the standard of similar products, and the development direction of the control structure of the whole automobile electronic product can be guided in many years in the future. FlexRay is the latest development after CAN and LIN and CAN effectively manage multiple security and comfort functions: FlexRay is suitable, for example, for line-by-Wire (X-by-Wire).
Further, the communication component 12 communicates or is connected to the ECU21 using a wireless communication link, as a variation of the present invention, the communication module may implement a wireless communication link through a short range communication module, such as WiFi, bluetooth, NFC, ZigBee, etc., and in a preferred embodiment, the communication component 12 is connected to the ECU through a CAN link or an ethernet link.

Similarly, signals transmitted by the ECU in the vehicle to the outside are also transmitted to the processor 13 through the communication unit 12 and processed, and the processed signals are transmitted to the antenna unit 11 by the processor 13 and then transmitted to an external server or terminal device, such as a mobile terminal, through the antenna unit 11.

For example, in the case where the antenna component 11 is a 4G antenna, in the preferred embodiment, a sub-processor and a corresponding communication port are integrated in the 4G antenna, the sub-processor communicates with the main processor 13, and accordingly, a signal that the main processor 13 needs to send is sent to the communication port through the sub-processor, and further, the communication port sends the signal to the outside.
