The technical solution of the present application is explained with specific examples.
Example 1
Fig. 1 is a schematic structural diagram of a vehicle-mounted communication device according to the present application.
The in-vehicle communication apparatus includes a satellite phone module 200, a satellite phone antenna 300, and a central processor 400.
The satellite phone module 200 is disposed inside the vehicle-mounted communication device main body 100 and connected to the central processing unit 400 to receive various control signals from the central processing unit 400.
The satellite phone antenna 300 is disposed outside the vehicle-mounted communication device main body 100, and is connected to the satellite phone module 200 through a radio frequency line.
The in-vehicle communication apparatus main body 100 may have a square box shape, a hemispherical shape, or the like, which is not limited in the present application. The satellite phone module 200 of the present application is disposed inside this in-vehicle communication device main body 100, and is packaged, and the in-vehicle communication device is generally disposed inside a vehicle, such as in front of a passenger seat or a main driver seat, where it is convenient to operate. The in-vehicle communication device main body 100 is externally provided with an interface to which a radio frequency line is connected so that the satellite phone module 200 can be connected with the satellite phone antenna 300 provided externally to receive a satellite signal.
It should be noted that the satellite phone module 200 communicates with the satellite over the sky through the satellite phone antenna 300, so as to implement communication, unlike the existing 5G or 4G communication method, which does not depend on a base station, the communication area that can be covered by one satellite is far larger than the coverage area of the 5G or 4G base station, so that the user can perform satellite communication in any satellite signal covered area, and the satellite itself will not cause signal interruption due to a disaster, even if extreme disastrous weather such as earthquake and tsunami occurs, and when the general communication radio wave base station is destroyed or lost, the satellite radio wave can still reach, so the satellite phone module 200 and the satellite phone antenna 300 are installed.
While satellite-to-ground elevation angles are typically between 20 and 56, satellite phone antenna 300 has an upwardly directed beam that can be distinguished from ground reflections, thus almost completely avoiding deep multipath fading common in terrestrial systems. The satellite signal has a large elevation angle, so when the satellite signal passes through a crown and passes through obstacles such as branches and leaves, such as vegetation, the caused attenuation is reduced to only a few dB, and the satellite signal is different from the extremely low penetrability of common 5G or 4G signals to trees and buildings, the attenuation of satellite electric waves when the satellite electric waves penetrate through leaves is very small, so that the communication quality can be ensured, and a user can perform communication operation even in remote areas such as mountainous areas, and the like, so that the user can be prevented from failing to call for help to the outside after driving in a mountain and being in distress, and the user can perform satellite communication in extreme conditions and remote areas.
As an alternative embodiment, satellite signals in the 27GHz to 40GHz frequency band may be selected as the communication frequency band, and the satellite signals in the high frequency band have high throughput, so that the antenna apparatus may be smaller, and for a vehicle that originally carries many antennas, the space may be saved, and the smaller antenna may also protect the safety of an external antenna. It is also possible to use lower band satellite signals as the communication channel and use a retractable satellite phone antenna 300 that is extended when needed and retracted when not in use.
Further, the satellite phone module 200 may further include a frequency band adjusting device to adjust a frequency band of current communication, so as to ensure that a proper frequency band is selected for satellite communication under different conditions, so that a user may cope with more application scenarios.
As shown in fig. 2, the vehicle-mounted communication device further includes a plurality of functional modules 500.
The plurality of functional modules 500 are also connected to the central processor 400, and these functional modules 500 may be a 4G communication module or a 5G communication module, and a vehicle-road cooperative communication module and other functional modules 500 for communication. Each functional module 500 is independently disposed, and does not interfere with each other, and specifically, the functional modules may be connected through a CAN bus, so as to implement resource allocation of different functional modules 500 to the central processing unit 400.
Similarly, since the in-vehicle communication apparatus is equipped with the plurality of function modules 500, when a user specifically selects a certain function to use, the cpu 400 performs selection and processing, and for example, when telephone communication is performed using the satellite phone module 200, module switching operation is performed so that, when satellite communication is performed, requests and signals from the other function modules 500 are not received and processed, and a voice digital signal to be input to the satellite phone module 200 is not input to the other function modules. When the task of the current module is executed, the switching operation is finished, and the switching operation can be realized by software or by a circuit structure and software.
In an optional embodiment, the vehicle-mounted communication device may further include a storage module for storing voice signals to provide functions of recording or number recording, and the storage module may be a non-volatile storage medium, such as a hard disk, an SD card, and the like, to store data generated by the vehicle-mounted communication device during operation.
As shown in fig. 3, a schematic structural diagram of a satellite phone module 200 provided in the embodiment of the present application includes: a voice signal processor 210, a modulator 220, a demodulator 260, a transmitter 230, a receiver 250, and a duplexer 240.
Wherein, the voice signal processor 201 is connected with the central processing unit 400. Used for processing the voice signal transmitted from the outside.
Further, a microphone 211 and a speaker 212 may be connected to the voice signal processor 210. The microphone 211 and the speaker 212 may be provided inside the vehicle-mounted communication device main body 100, and the vehicle-mounted communication device main body 100 may be provided with a through hole for receiving and releasing sound, or may be provided outside and may be provided in a microphone form similar to a telephone.
The voice signal processor 210 is connected to the modulator 220 and the demodulator 260, respectively, the modulator 220 is connected to the transmitter 230, and the receiver 250 is connected to the demodulator 260.
The duplexer 240 is respectively connected to the transmitter 230 and the receiver 250, and is connected to the satellite phone antenna through a radio frequency line, and the duplexer 204 is used for isolating the transmitted and received signals, and ensuring that both the transmitter and the receiver can work normally at the same time.
When the satellite-borne satellite-based satellite communication system is used, sound emitted by a user reaches the voice signal processor 210 through the microphone 211, voice analog signals are converted into voice digital signals through the voice signal processor 210, the voice digital signals are subjected to relevant processing such as encryption and the like and then output to the modulator 220, the voice digital signals are subjected to radio-frequency modulation to form radio-frequency signals through the modulator, the modulated voice radio-frequency signals are subjected to radio-frequency amplification and filtering through the transmitter 230 and then enter the duplexer 240, transmitting and receiving signals are isolated through the duplexer 240, and the transmitting radio-frequency signals are transmitted to a satellite in the sky through the satellite-borne satellite-based telephone antenna 300.
The vehicle satellite phone antenna 300 receives a satellite radio frequency signal, the satellite radio frequency signal enters the receiver 250 for filtering and amplification after passing through the duplexer 240, then enters the demodulator 260 for demodulation, and the demodulated signal enters the voice digital signal processor 210 for decoding, digital-to-analog conversion and voice analog signal amplification, and then drives the loudspeaker 212 to produce sound. Therefore, a complete communication process is completed to support the functions of the user of sending the voice information to the outside and receiving and releasing the voice information transmitted from the outside.
In an alternative embodiment, the vehicle-mounted communication device may further include an encryption module, and the encryption module may be connected to the satellite phone module 200 to encrypt and decrypt the communication data.
The encryption module may be integrated as an integrated module, integrated within the satellite phone module 200, or connected to the satellite phone module 200 as a separate hardware. When the integration is in the satellite telephone module 200, the components and parts with small volume can be adopted to save the installation space, and when the components and parts are used as independent hardware, corresponding interfaces can be reserved on the satellite telephone module 200 to facilitate the connection of the encryption module, and the connection mode can be through arranging and inserting connectors or connecting lines.
In an alternative embodiment, the encryption module may also be integrated in the central processing unit 400 to support encryption of all communication services of the vehicle-mounted communication device, such as 5G or 4G communication, and other vehicle-road cooperative communication, so as to reduce the need to separately set the encryption module in the other functional module 500, and further save the overall cost.
Fig. 4 is a schematic diagram of a satellite phone antenna connection method according to an embodiment of the present application.
In order to make the satellite phone antenna 300 receive good antenna signals, the satellite phone antenna 300 may be disposed on the top of the vehicle body as shown in fig. 4, and in order to make the wiring simple, the vehicle-mounted communication device main body 100 may also be disposed on the ceiling inside the vehicle at a position corresponding to the satellite phone antenna 300 disposed outside, so that a roof is separated between the antenna and the communication device, the connection is convenient, and a long rf line does not need to be connected, and in this case, a more stable rf column may be used for the connection to reduce the space occupied by the rf line.
The satellite phone antenna 300 may be disposed at the front or rear of the vehicle in addition to the roof, and the in-vehicle communication device main body 100 may be moved according to the position where the satellite phone antenna 300 is disposed, and when the satellite phone antenna 300 is disposed at the front or rear of the vehicle, since the satellite phone antenna 300 is spaced apart from the satellite phone antenna 300, the satellite phone antenna may pass through the vehicle through a radio frequency line to be connected thereto, and when the satellite phone antenna 300 is disposed at the front, the in-vehicle communication device main body 100 may be disposed at the driver seat side or the passenger seat side. When the satellite phone antenna 300 is disposed at the rear, the in-vehicle communication device main body 100 may be disposed behind the rear driver seat.
