[0003] However, in practical applications, most OBUs are more suitable for small vehicles. Even after adding an external fin antenna, these solutions are still not ideal for large or special vehicles, with problems such as poor communication, strong signal interference, and many dead zones, which seriously affect the traffic safety of large or special vehicles. Summary of the Invention

[0004] This invention provides an antenna module control system, method, and storage medium, which increases the number of antenna modules used for communication, constructs a new control system for special scenarios and communication entities, and offloads the processing of antenna signals, thereby improving the quality of antenna signals received by the vehicle-mounted intelligent terminal and meeting the communication needs of large vehicles and special vehicles.

[0006] Each antenna module is connected to the vehicle-mounted intelligent terminal, and there is a connection between every two antenna modules.

[0007] Each antenna module is used to switch the signal transmission state to the signal reception state during initialization and send the received initial antenna reception signal to the vehicle-mounted intelligent terminal.

[0008] The vehicle-mounted intelligent terminal is used to determine the identity information of each antenna module based on the signal source and strength information of the signals received by each initial antenna, and send the identity information to the corresponding antenna module to divide each antenna module into a master antenna module and a slave antenna module.

[0009] Each slave antenna module is used to receive signals received by the slave module antenna in signal receiving mode, and to send the signals received by the slave module antenna to the main antenna module;

[0010] The main antenna module is used to receive the main module antenna signal in the signal receiving state, and to superimpose the main module antenna signal with the signals received by each slave module antenna, and send the generated superimposed antenna signal to the vehicle intelligent terminal.

[0011] Secondly, embodiments of the present invention also provide an antenna module control method, applied in an antenna module control system, comprising:

[0012] During initialization, each antenna module switches its signal transmission state to signal reception state and sends the received initial antenna reception signal to the vehicle-mounted intelligent terminal.

[0013] The vehicle-mounted intelligent terminal determines the identity information of each antenna module based on the signal source and strength information of the signals received by each initial antenna, and sends the identity information to the corresponding antenna module to divide each antenna module into a main antenna module and a slave antenna module.

[0014] Each slave antenna module receives the signal received by the slave antenna in signal receiving mode and sends the signal received by the slave antenna to the main antenna module;

[0015] In signal receiving mode, the main antenna module receives the main module antenna signal and superimposes the main module antenna signal with the signals received by each slave module antenna, and sends the generated superimposed antenna signal to the vehicle intelligent terminal.

[0017] This invention provides an antenna module control system, method, and storage medium. The antenna module control system includes: an in-vehicle intelligent terminal and at least two antenna modules installed on the vehicle; each antenna module is connected to the in-vehicle intelligent terminal, and every two antenna modules are connected to each other; each antenna module is used to switch the signal transmission state to the signal reception state during initialization and send the received initial antenna reception signal to the in-vehicle intelligent terminal; the in-vehicle intelligent terminal is used to determine the identity information of each antenna module based on the signal source and strength information of each initial antenna reception signal, and send each identity information to the corresponding antenna module to divide each antenna module into a main antenna module and a slave antenna module; each slave antenna module is used to receive the slave module antenna reception signal in the signal reception state and send the slave module antenna reception signal to the main antenna module; the main antenna module is used to receive the main module antenna reception signal in the signal reception state, and superimpose the main module antenna reception signal with the slave module antenna reception signals, and send the generated superimposed antenna reception signal to the in-vehicle intelligent terminal. By adopting the above technical solution, multiple identical antenna modules are used in the vehicle to enhance communication strength and stability. By utilizing the signal source and strength information of the received signals collected by each antenna module, different antenna modules are assigned different identities.

[0026] Example 1

[0027] Figure 1 This is a schematic diagram of an antenna module control system according to Embodiment 1 of the present invention. This embodiment is applicable to situations where traditional single-board antennas or fin antennas cannot meet the communication requirements of vehicle-mounted intelligent terminals. The antenna module control system 1 includes: an vehicle-mounted intelligent terminal 11 and at least two antenna modules 12 installed on the vehicle. Figure 1 Taking two antenna modules 12 as an example.

[0028] Each antenna module 12 is connected to the vehicle-mounted intelligent terminal 11, and every two antenna modules 12 are connected to each other.

[0029] Each antenna module 12 is used to switch the signal transmission state to the signal reception state during initialization and send the received initial antenna reception signal to the vehicle-mounted intelligent terminal 11.

[0030] The vehicle-mounted intelligent terminal 11 is used to determine the identity information of each antenna module 12 based on the signal source and strength information of the signals received by each initial antenna, and send each identity information to the corresponding antenna module 12 to divide each antenna module into a main antenna module 121 and a slave antenna module 122.

[0031] Each slave antenna module 122 is used to receive the signal received by the slave antenna in the signal receiving state, and to send the signal received by the slave antenna to the main antenna module 121;

[0032] The main antenna module 121 is used to receive the main module antenna received signal in the signal receiving state, and to superimpose the main module antenna received signal with the received signals of each slave module antenna, and send the generated superimposed antenna received signal to the vehicle-mounted intelligent terminal 11.

[0033] In this embodiment, the in-vehicle intelligent terminal 11 can be specifically understood as a terminal device installed in a vehicle that integrates GPS technology, mileage positioning technology, and vehicle black box technology. It is understood that the in-vehicle intelligent terminal 11 has external communication requirements. Existing in-vehicle intelligent terminals often need to support multiple communication methods including BDS / GPS / Galileo, WLAN, GPRS, 4G / 5G, and V2X. In small vehicles, the in-vehicle intelligent terminal often supports these requirements through a single onboard antenna or fin antenna. However, the functions of these antennas are relatively limited, and their communication performance is insufficient in large vehicles. The antenna module 12 can be specifically understood as a collection of devices installed in the vehicle for transmitting or receiving wireless signals. Optionally, the multiple antenna modules 12 in this embodiment are of the same type, designed to improve the stability of similar signals. For example, the antenna module 12 in this embodiment can be a vehicle-to-everything (V2X) module; this embodiment does not limit this. The signal transmission state can be specifically understood as the state of the antenna module 12 when transmitting signals to an external signal source. Optionally, the signal transmission state may include a signal receiving state and a signal transmitting state. Specifically, the signal receiving state can be understood as the state in which the antenna module 12 receives signals from an external signal source, and the signal transmitting state can be understood as the state in which the antenna module 12 will transmit signals to an external signal source. The initial antenna received signal can be specifically understood as the antenna signal obtained by the antenna module 12 during initialization after processing the signal received from the external signal source, which can be directly received and utilized by the vehicle-mounted intelligent terminal 11. The identity information can be specifically understood as the information used to classify the master and slave identities of each antenna module 11. The master antenna module 121 can be specifically understood as the antenna module 12 that receives signals with higher strength from external signal sources, and is responsible for performing same-source superposition data processing on the signals received by each antenna module 12 during the actual signal reception process, and communicating with the vehicle-mounted intelligent terminal 11. Specifically, antenna module 122 can be understood as the antenna module 12 that receives signals with low strength from external signal sources and does not directly communicate with the vehicle-mounted intelligent terminal 11 during actual signal reception. Instead, it aggregates the received signals to the main antenna module 121 for processing. The signal received by the module antenna can be understood as the antenna signal obtained by the antenna module 122 after processing the signals received from external signal sources, which can be directly received and utilized by the vehicle-mounted intelligent terminal 11. The signal received by the main module antenna can be understood as the antenna signal obtained by the main antenna module 121 after processing the signals received from external signal sources, which can be directly received and utilized by the vehicle-mounted intelligent terminal 11. The superimposed antenna received signal can be understood as the antenna signal generated by superimposing the signals received by each antenna module 12 from the same signal source during the signal reception phase.

[0034] Specifically, at least two antenna modules 12 installed on the vehicle are connected to the in-vehicle intelligent terminal 11, and the antenna modules 12 are interconnected to enable signal transmission between different antenna modules 12. When the vehicle is powered on, the in-vehicle intelligent terminal 11 and each antenna module 12 are initialized simultaneously. During the initialization phase, each antenna module 12 switches its signal transmission state to signal reception state, receiving signals broadcast by external signal sources. After receiving the signal, the antenna module 12 processes the received signal through processes such as filtering, amplification, and format conversion, determining the processed signal as the initial antenna received signal, and sends the initial antenna received signal to the in-vehicle intelligent terminal 11. During the initialization phase, the in-vehicle intelligent terminal 11 compares the strength information of initial antenna received signals belonging to the same signal source based on the signal source and strength information of each received initial antenna received signal. Based on the comparison result, it assigns master and slave roles to different antenna modules 12, that is, determines the identity information of different antenna modules 12, and sends each identity information to the corresponding antenna module 12. This allows antenna modules 12 to divide themselves into master antenna module 121 and slave antenna modules 122 after receiving their respective identification information. After completing the master-slave division for each antenna module 12, it can be considered that the master antenna module 121 will serve as the main receiver of the external signal source, and each slave antenna module 122 will serve as the secondary receiver of the external signal source. The master antenna module 121 and the slave antenna modules 122 together serve as the signal transmitters to the external signal source. During normal communication, both the main antenna module 121 and the slave antenna module 122 will receive and process signals from external signal sources in signal receiving mode. The signal received by the main antenna module 121 is processed into the main module antenna receiving signal, and the signal received by the slave antenna module 122 is processed into the slave module antenna receiving signal. The slave antenna module 122 will send the signal received from the slave module antenna to the main antenna module 121 through the communication connection with the main antenna module 121. The main antenna module 121 will perform co-source superposition of the signals received by each slave module antenna and the main module antenna, and send the generated superimposed antenna receiving signal with the maximum packet loss compensation to the vehicle intelligent terminal.

[0035] This invention provides an antenna module control system, method, and storage medium. The antenna module control system includes: an in-vehicle intelligent terminal and at least two antenna modules installed on the vehicle; each antenna module is connected to the in-vehicle intelligent terminal, and every two antenna modules are interconnected; each antenna module is used to switch its signal transmission state to a signal reception state during initialization and send the received initial antenna reception signal to the in-vehicle intelligent terminal; the in-vehicle intelligent terminal is used to determine the identity information of each antenna module based on the signal source and strength information of each initial antenna reception signal, and send each identity information to the corresponding antenna module to divide each antenna module into a main antenna module and a slave antenna module; each slave antenna module is used to receive the slave module antenna reception signal in the signal reception state and send the slave module antenna reception signal to the main antenna module; the main antenna module is used to receive the main module antenna reception signal in the signal reception state, and superimpose the main module antenna reception signal with the slave module antenna reception signals, and send the generated superimposed antenna reception signal to the in-vehicle intelligent terminal. By adopting the above technical solution, multiple identical antenna modules are used in the vehicle to enhance communication strength and stability. By utilizing the signal source and strength information of the received signals collected by each antenna module, different antenna modules are assigned different identities. This allows the received signals collected by each antenna module to be superimposed within the same antenna module, reducing the signal strength reduction and signal integrity issues caused by packet loss in signals received by a single antenna module. Simultaneously, data processing operations for antenna signal processing are offloaded, reducing the data processing burden on the vehicle-mounted intelligent terminal. Overall, this improves the quality of the antenna signals received by the vehicle-mounted intelligent terminal, meeting the communication needs of large vehicles and special vehicles.

[0036] Example 2

[0037] Figure 2 This is a schematic diagram of another antenna module control system provided in Embodiment 2 of the present invention. The technical solution of the present invention is further optimized based on the above-mentioned optional technical solutions, such as... Figure 2 As shown, the antenna module control system 1 includes: an in-vehicle intelligent terminal 11 and at least two antenna modules 12 installed on the vehicle. Each antenna module 12 includes: a radio frequency antenna 123, a radio frequency switch 124, a radio frequency chip 125, and a module main control chip 126. Figure 2 Taking two antenna modules 12 as an example, it can be understood that the main antenna module 121 and the slave antenna module 122 are structurally identical, that is, both the main antenna module 121 and the slave antenna module 122 include an RF antenna 123, an RF switch 124, an RF chip 125 and a module main control chip 126.

[0038] The radio frequency antenna 123 is connected to the radio frequency switch 124, the radio frequency switch 124 is connected to the radio frequency chip 125, the radio frequency chip 125 is connected to the module main control chip 126, the radio frequency chip 125 and the module main control chip 126 are respectively connected to the vehicle intelligent terminal 11, and the radio frequency chips 125 in every two antenna modules 12 are connected to each other.

[0039] The radio frequency antenna 123 is used to receive the antenna received signal sent by the signal source and to send the antenna transmitted signal to the signal source.

[0040] The radio frequency chip 125 is used to send an antenna reception control command to the radio frequency switch 124 during initialization, and to receive the antenna reception signal transmitted by the radio frequency antenna through the radio frequency switch 124, and to send the processed initial antenna reception signal to the vehicle intelligent terminal 11.

[0041] The radio frequency switch 124 is used to switch the signal transmission state of the radio frequency antenna 123 to the signal reception state in response to the antenna reception control command.

[0042] The module's main control chip 126 is used to receive identity information sent by the vehicle-mounted intelligent terminal 11 and to classify the antenna module 12 by identity.

[0043] In this embodiment, the RF switch 124 can be specifically understood as a device in the antenna module 12 used to control the RF antenna 123 and switch the signal transmission state of the RF antenna 123. Optionally, the RF switch 124 can be a switching switch, which can be a mechanical switching switch, such as a single-pole double-throw switch, where the two switching terminals of the single-pole double-throw switch are used to switch the corresponding RF antenna 123 to a signal receiving state and a signal transmitting state, respectively. The RF switch 124 can also be an electronic switching switch, such as a switch with two switching paths composed of switching transistors. This embodiment of the invention does not limit this. The RF chip 125 can be specifically understood as a control chip in the antenna module 12 used to enhance and convert the signal received by the RF antenna 123, and to generate a control chip used to control the RF switch 124 to adjust the signal transmission state of the RF antenna 123. The module main control chip 126 can be specifically understood as a control chip in the antenna module 12 used to identify the identity information of the antenna module 12 and to perform homogeneous signal superposition on the acquired signals when the antenna module 12 is the main antenna module 121. The antenna receiving control command can be specifically understood as a control command used to control the RF switch 124 to switch the signal transmission state of the RF antenna 123 to the signal receiving state.

[0044] Specifically, during initialization, the RF chip 125 generates an antenna reception control command to control the RF switch 124 to adjust the signal transmission state of the RF antenna 123. Upon receiving the antenna reception control command, the RF switch 124 switches the signal transmission state of its corresponding RF antenna 123 to the signal reception state. This allows the RF antenna 123 to receive the antenna reception signal broadcast by the signal source and transmits it via the RF switch 124 to the RF chip 125. The RF chip 125 then processes the antenna reception signal, performing processes such as filtering, amplification, and format conversion, before sending the resulting initial antenna reception signal to the vehicle-mounted intelligent terminal 11. After the initial antenna reception signal is sent, the module master control chip 126 of the antenna module 12 receives the identity information sent by the vehicle-mounted intelligent terminal 11. The module master control chip 126 then uses this identity information to classify the antenna module 12, determining whether it belongs to the main antenna module 121 or the secondary antenna module 122.

[0045] Optionally, when the antenna module 12 is a slave antenna module 122, the RF chip 125 of the slave antenna module 122 is also used to: receive the slave module antenna received signal transmitted by the RF antenna 123 via the RF switch 124 in the signal receiving state, and send the slave module antenna received signal to the RF chip 125 of the main antenna module 121.

[0046] Optionally, when the antenna module 12 is the main antenna module 121, the radio frequency chip 125 of the main antenna module 121 is also used to: receive the main module antenna receiving signal transmitted by the radio frequency antenna 123 via the radio frequency switch 124 in the signal receiving state, and send the main module antenna receiving signal and the received signals from each of the slave module antennas to the module main control chip 126.

[0047] Optionally, the module master control chip 126 of the main antenna module 121 is also used to: superimpose the received signal of the main module antenna and the received signals of each slave module antenna, and send the generated superimposed antenna received signal to the vehicle-mounted intelligent terminal 11.

[0048] Optional, Figure 3 This is a schematic diagram of another antenna module control system provided in Embodiment 2 of the present invention, which is a further refinement based on the above-mentioned optional embodiments, such as... Figure 3 As shown, the vehicle-mounted intelligent terminal 11 includes a main control module 111 and a signal detection module 112.

[0049] The main control module 111 is connected to the signal detection module 112, as well as the radio frequency chip 125 and the module main control chip 126 of each antenna module 12.

[0050] The main control module 111 is used to receive the initial antenna receiving signals sent by each RF chip 125 during initialization, filter the initial antenna receiving signals according to the signal source of each initial antenna receiving signal to obtain the same source initial antenna receiving signal, and send the same source initial signal strength information corresponding to each same source initial antenna receiving signal to the signal detection module 112.

[0051] The signal detection module 112 is used to compare the initial signal strength information of each source with a first preset strength threshold, and send the generated first comparison result to the main control module 111;

[0052] The main control module 111 is also used to generate the identity information of each antenna module 12 according to the first comparison result, and send the identity information to the corresponding antenna module 12 respectively.

[0053] In this embodiment, the main control module 111 can be specifically understood as a processor in the vehicle-mounted intelligent terminal 11 that processes the received signals, generates antenna transmission signals for external transmission, and generates control signals for each antenna module 12 connected to it. For example, the main control module 111 can be a V2X main control chip, and this embodiment of the invention does not limit this. The signal detection module 112 can be specifically understood as a processor in the vehicle-mounted intelligent terminal 11 that compares the received signal strength information and sends the generated comparison results to the main control module 111 for the main control module 111 to determine and select. For example, the signal detection module 112 can be a detection chip, and this embodiment of the invention does not limit this. The initial antenna received signal from the same source can be specifically understood as the initial antenna received signal from the same signal source among the initial antenna received signals. The first preset strength threshold can be specifically understood as a signal strength threshold preset according to actual conditions, used to determine whether the antenna signal received strength meets the communication requirements when the communication link is established.

[0054] Specifically, during initialization, the main control module 111 receives the initial antenna receiving signals sent by the RF chips 125 corresponding to each antenna module 12. Since each initial antenna receiving signal contains the signal source from which it originates, the main control module 111 can filter the signal sources of each initial antenna receiving signal to determine those initial antenna receiving signals belonging to the same signal source. Furthermore, since each initial antenna receiving signal also contains the signal strength information of that signal, after determining the initial antenna receiving signals from the same source, its corresponding signal strength information can be identified as the initial signal strength information from the same source. The initial signal strength information from the same source is then sent to the signal detection module 112 for comparison. The comparison result is identified as the first comparison result and sent to the main control module 111. This allows the main control module 111 to determine the identity information of each antenna module 12 based on the first comparison result and send the identity information to the corresponding antenna module 12 to enter the signal receiving state for normal operation.

[0055] Optional, main control module 111, specifically used for:

[0056] When the first comparison result shows that there is a homogeneous initial signal strength information greater than the first preset strength threshold, the identity information of the antenna module 12 corresponding to the maximum homogeneous initial signal strength information is determined as the main module identity information, and the identity information of the other antenna modules 12 is determined as the slave module identity information.

[0057] When the first comparison result indicates that there is no homogeneous initial signal strength information greater than the first preset strength threshold, each RF chip 125 acquires a preset number of homogeneous initial antenna received signal sets, sends the average homogeneous initial signal strength corresponding to each homogeneous initial antenna received signal set to the signal detection module 112, and determines the identity information of each antenna module 12 based on the second comparison result generated by the signal detection module 112, and sends each identity information 12 to the corresponding antenna module.

[0058] Specifically, when the main control module 111 receives the first comparison result, it parses the first comparison result. If the first comparison result shows that there is at least one initial signal strength information of the same source that is greater than the first preset strength threshold, then it can be considered that there is at least one antenna module 12 that meets the communication strength requirements with the signal source. At this time, the main control module 111 determines the largest initial signal strength information of the same source from the initial signal strength information of the same source that is greater than the first preset strength threshold, and determines the identity information of the antenna module 12 corresponding to the largest initial signal strength information of the same source as the main module identity information, and determines the identity information of the antenna module 12 corresponding to the other initial signal strength information of the same source as the slave module identity information, and sends its own corresponding identity information to each antenna module 12.

[0059] Specifically, if the first comparison result indicates that there is no initial signal strength information of the same source greater than the first preset strength threshold among the initial signal strength information of each source, it can be considered that the antenna received signal strength of each antenna module 12 does not meet the conditions for establishing a communication link with the signal source in the initial acquisition. At this time, the main control module 111 can reacquire the set of initial antenna received signals of the same source for a preset number of frames from the radio frequency chip 125 of each antenna module 12. That is, each antenna module 12 repeatedly acquires the initial antenna received signals of the same source for a preset number of frames for the signal source corresponding to the initial signal strength information of the same source, and sends the set of initial antenna received signals of the same source to the main control module 111. The main control module 111 determines the average value of the initial signal strength of the same source for each set of initial antenna received signals of the same source, and sends the average value of the initial signal strength of the same source to the signal detection module 112. The signal detection module 112 compares the average initial signal strength of each source and sends the generated second comparison result to the main control module 111, so that the main control module 111 can determine the identity information of each antenna module 12 according to the second comparison result and send the identity information to each antenna module 12 accordingly.

[0060] Optionally, the main control module 111 is specifically used to: determine the identity information of the main module based on the identity information of the antenna module 12 corresponding to the average initial signal strength of the largest homogeneous source in the second comparison result, and determine the identity information of other antenna modules 12 as the identity information of slave modules.

[0061] Specifically, since the second comparison result includes the comparison results of the magnitude of the average initial signal strength of each source, the main control module 111 can determine the maximum average initial signal strength of each source based on the second comparison result, and can determine the identity information of the antenna module 12 corresponding to the maximum average initial signal strength as the main module identity information, and determine the identity information of the other antenna modules 12 as the slave module identity information.

[0062] Optionally, the main control module 111 is further configured to: send the superimposed antenna signal strength information of the received superimposed antenna signal to the signal detection module 112, and receive the third comparison result fed back by the signal detection module 112; wherein, the third comparison result is the result generated by the signal detection module by comparing the superimposed antenna signal strength information with the second preset strength threshold; when the third comparison result is less than, initialize each antenna module.

[0063] In this embodiment, the second preset strength threshold can be understood as a signal strength threshold that is preset according to the actual situation, used to determine whether the antenna signal receiving strength meets the communication requirements after the antenna module 12 establishes a communication link with the external signal source.

[0064] Specifically, after the identity information of each antenna module 12 has been determined, the main control module 111 receives the superimposed antenna received signal sent by the module main control chip 126 of the main antenna module 121. The main control module 111 sends the superimposed antenna signal strength information of the superimposed antenna received signal to the signal detection module 112, so that the signal detection module 112 can compare the superimposed antenna signal strength information according to the preset second strength threshold, and the main control module 111 can monitor the current communication stability according to the received third comparison result. When the third comparison result is less than, that is, when the superimposed antenna signal strength information is less than the second preset strength threshold, it can be considered that the established communication link is difficult to meet the communication requirements. At this time, the main control module 111 will control each antenna module 12 to re-initialize in order to re-identify each antenna module 12.

[0065] The antenna module control system provided in this embodiment of the invention clarifies that the antenna module includes a radio frequency antenna, a radio frequency switch, a radio frequency chip, and a module main control chip. Through the module main control chip with data processing function, different antenna modules are assigned different identities, and the antenna received signals collected by different antenna modules are superimposed in the module main control chip of the main antenna module before being sent to the vehicle-mounted intelligent terminal for processing. This offloads the data processing operations for antenna signal processing, reduces the data processing pressure on the vehicle-mounted intelligent terminal, and improves the overall quality of the antenna signal received by the vehicle-mounted intelligent terminal, meeting the communication needs of large vehicles and special vehicles.

[0068] S301. During initialization, each antenna module switches its signal transmission state to signal reception state and sends the received initial antenna reception signal to the vehicle-mounted intelligent terminal.

[0069] Optionally, the antenna module includes: an RF antenna, an RF switch, an RF chip, and a module main control chip; each antenna module switches its signal transmission state to signal reception state during initialization and sends the received initial antenna reception signal to the vehicle-mounted intelligent terminal, including:

[0070] S3011, the RF chip sends an antenna reception control command to the RF switch during initialization.

[0071] S3012, the RF switch responds to the antenna receiving control command and switches the RF antenna from signal transmission state to signal receiving state.

[0072] S3013 The radio frequency chip receives the antenna reception signal transmitted by the radio frequency antenna through the radio frequency switch, and sends the processed initial antenna reception signal to the vehicle intelligent terminal.

[0073] S302. The vehicle-mounted intelligent terminal determines the identity information of each antenna module based on the signal source and strength information of the signals received by each initial antenna, and sends the identity information to the corresponding antenna module to divide each antenna module into a main antenna module and a slave antenna module.

[0074] Optionally, the vehicle-mounted intelligent terminal includes: a main control module and a signal detection module; the vehicle-mounted intelligent terminal determines the identity information of each antenna module based on the signal source and strength information of the signals received by each initial antenna, and sends the identity information to the corresponding antenna module to classify each antenna module into a main antenna module and a slave antenna module, specifically including the following steps:

[0075] S3021. During initialization, the main control module receives the initial antenna reception signals sent by each RF chip, filters the signal sources of each initial antenna reception signal to obtain the same source initial antenna reception signals, and sends the same source initial signal strength information corresponding to each same source initial antenna reception signal to the signal detection module.

[0076] S3022, The signal detection module compares the initial signal strength information of each source with the first preset strength threshold, and sends the generated first comparison result to the main control module.

[0077] S3023. The main control module generates the identity information of each antenna module based on the first comparison result, and sends the identity information to the corresponding antenna module respectively.

[0078] Optionally, the main control module generates the identity information of each antenna module based on the first comparison result, and sends the identity information to the corresponding antenna module, including:

[0079] When the first comparison result shows that there is a homogeneous initial signal strength information greater than the first preset strength threshold, the identity information of the antenna module corresponding to the maximum homogeneous initial signal strength information is determined as the main module identity information, and the identity information of other antenna modules is determined as the slave module identity information.

[0080] When the first comparison result indicates that there is no homogeneous initial signal strength information greater than the first preset strength threshold, each radio frequency chip obtains a set of homogeneous initial antenna received signals for a preset number of frames, sends the average homogeneous initial signal strength corresponding to each set of homogeneous initial antenna received signals to the signal detection module, and determines the identity information of each antenna module based on the second comparison result generated by the signal detection module, and sends each identity information to the corresponding antenna module.

[0081] Optionally, the identity information of each antenna module is determined based on the second comparison result generated by the signal detection module, and the identity information is sent to the corresponding antenna module, including:

[0082] The identity information of the main module is determined based on the identity information of the antenna module corresponding to the average initial signal strength of the largest homogeneous source in the second comparison result, and the identity information of the other antenna modules is determined as the identity information of the slave modules.

[0083] S3024. The main control chip of each module receives the identity information sent by the vehicle-mounted intelligent terminal and classifies the antenna modules by identity.

[0084] S303. Each slave antenna module receives the signal received by the slave antenna in the signal receiving state and sends the signal received by the slave antenna to the main antenna module.

[0087] Optionally, the RF chip of the main antenna module receives the main module antenna received signal transmitted by the RF antenna via the RF switch in the signal receiving state, and sends the main module antenna received signal and the received signals from each slave module antenna to the module main control chip; the module main control chip of the main antenna module performs homogeneous superposition of the main module antenna received signal and the received signals from each slave module antenna, and sends the generated superimposed antenna received signal to the vehicle intelligent terminal.

[0089] The main control module sends the superimposed antenna signal strength information of the received superimposed antenna signal to the signal detection module, and receives the third comparison result fed back by the signal detection module; wherein, the third comparison result is the result generated by the signal detection module by comparing the superimposed antenna signal strength information with the second preset strength threshold;

[0090] When the third comparison result is less than, each antenna module is initialized.

[0091] The technical solution in this embodiment enhances communication strength and stability by employing multiple similar antenna modules on the vehicle. By utilizing the signal source and strength information of the received signals collected by each antenna module, different antenna modules are assigned different identities. This allows the received signals collected by each antenna module to be superimposed within the same antenna module, reducing the signal strength reduction and signal integrity issues caused by packet loss in signals received by a single antenna module. Simultaneously, it offloads data processing operations for antenna signal processing, reducing the data processing burden on the in-vehicle intelligent terminal. Overall, this improves the quality of the antenna signals received by the in-vehicle intelligent terminal, meeting the communication needs of large vehicles and special vehicles.
