[0026] The following will be combined with the drawings in the embodiments of this article to clearly and completely describe the technical solutions in the embodiments of this article. Obviously, the described embodiments are only part of the embodiments of this article, not all of the embodiments. Based on the embodiments of this article, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this article.

[0027] It should be noted that the terms "first", "second", etc. in the specification and claims of this article and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of this article described here can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, device, product or equipment that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0028] In order to solve the above problems, the embodiment of this article provides a vehicle-mounted satellite communication system. Figure 1 , Figure 1 A schematic structural diagram of a vehicle-mounted satellite communication system provided in an embodiment of this invention is shown, wherein the system comprises: a human-computer interaction device, a baseband integrated device and a satellite antenna;

[0029] The human-computer interaction device is connected to the baseband integrated device, and the human-computer interaction device is used to send a control signal triggered by a preset action to the baseband integrated device, wherein the human-computer interaction device is a terminal or a vehicle-mounted central control screen;

[0030] The baseband integrated device is connected to the satellite antenna and is used to control the satellite antenna according to the received control signal to implement switching, antenna pointing, satellite signal monitoring, satellite beam switching, upgrading or fault detection operations of the satellite antenna;

[0031] The satellite antenna is used to receive and send band communication signals of the communication satellite to achieve communication with the communication satellite.

[0032] Specifically, the vehicle-mounted satellite communication system can be set on the vehicle, wherein the human-computer interaction device can be set on the center console of the vehicle. The baseband integrated device can be set in an area inside the vehicle that is invisible to the user, such as in the chassis where the engine is located. The baseband integrated device can be understood as a device box that integrates multiple devices. The size of the baseband integrated device is small relative to the existing cabinet size.

[0033] The terminal may include physical devices such as smart phones, desktop computers, tablet computers, laptops, digital assistants, smart wearable devices, etc., and may also include software running in the physical device, such as an application (Application, referred to as App), which may be an application specifically providing satellite antenna control. A user may log in to the application through pre-registered account information, and the account information may include an account number (identification) and a password. The operating system running on the physical device in the embodiment of the present application may include but is not limited to Android system, IOS system, Linux, Unix, Windows, etc. The terminal may include a UI (User Interface) layer, and the terminal provides input and display of satellite antenna control to the outside through the UI layer.

[0034] The in-vehicle central control screen can be understood as the central control display screen (smart car screen) in the vehicle. Because the smart car screen is the basic configuration of the current new car models, and the mobile phone is the user's own device, using the smart car screen or mobile phone to control the antenna will not increase the number of devices in the car and will not take up space in the car. In addition, the operation method of the smart car or mobile phone is more user-friendly.

[0035] Specifically, the satellite antenna may be a low-profile flat-panel array antenna.

[0036] The human-computer interaction device can be used to display the working status of the satellite antenna, where the working status can be the switch of the satellite antenna, the antenna pointing, the satellite signal strength, the satellite beams of multiple different communication satellites, the version information of the current satellite antenna, and the fault information, etc. It is also used to send a control signal for triggering based on a preset action to the baseband integrated device.

[0037] In the implementation application, a control unit corresponding to the satellite antenna's switching, antenna pointing, satellite signal monitoring, satellite beam switching, upgrade or fault detection operations can be provided in the human-computer interaction device. The user can generate a corresponding control signal by executing a corresponding preset action trigger in the human-computer interaction device. The human-computer interaction device can send the above-generated control signal to the baseband integration device. The baseband integration device can control the satellite antenna according to the received control signal. The operation of controlling the satellite antenna can be the satellite antenna's switching, antenna pointing, satellite signal monitoring, satellite beam switching, upgrade or fault detection operations.

[0038] Among them, the switch of the satellite antenna is used to characterize whether the satellite antenna is turned on or off. Antenna pointing is used to characterize the elevation angle, azimuth angle and roll polarization angle of the satellite antenna. Satellite signal monitoring is used to characterize the signal strength monitoring between the satellite antenna and the corresponding communication satellite. Satellite beam switching is used to characterize the switching connection with different communication satellites. Upgrade is used to characterize the program upgrade of the current satellite antenna. Fault detection is used to characterize whether there is a fault in the vehicle-mounted satellite communication system.

[0039] It is understandable that the baseband integrated device and the satellite antenna and the satellite antenna can be connected via wired or wireless means, such as Bluetooth, WIFI, CAN bus, etc.

[0040] The vehicle-mounted satellite communication system provided by the embodiment of this specification can be used by the user to trigger different control signals through the human-computer interaction device and send the control signals to the baseband integrated device. The baseband integrated device can control the satellite antenna according to the received control signal to realize the satellite antenna switch, antenna pointing, satellite signal monitoring, satellite beam switching, upgrade or fault detection and other operations. There is no need to set up a corresponding operation cabinet in the vehicle, which improves the vehicle space. The above operations are performed through the human-computer interaction device, which reduces the difficulty of different users to operate the vehicle-mounted satellite communication system, meets the use requirements of different users for the vehicle-mounted satellite communication system, and improves the popularity and utilization rate of the vehicle-mounted satellite communication system. After the satellite antenna is connected to the communication satellite, the user can also operate the human-computer interaction device according to the signal strength (the result of satellite signal monitoring) to realize the switching of different communication satellites (satellite beam switching), thereby improving communication efficiency.

[0041] Based on the above embodiments, in one embodiment of this specification, the baseband integrated device includes: a control component;

[0042] The human-computer interaction device is connected to the baseband integrated device via the control component, and the control component is used to control the satellite antenna according to the received control signal.

[0043] Specifically, the control component can be understood as a small main control circuit board. The control component can be provided with a serial port matching the satellite antenna, and communicate with the satellite antenna through the serial port. The control component can generate a corresponding control interaction signal according to the received control signal. The control interaction signal can be used to control the switch of the satellite antenna, antenna pointing, satellite signal monitoring, satellite beam switching, upgrade or fault detection, etc., and can realize the output of the control signal to control the satellite antenna.

[0044] In addition, the control component can also provide power to the satellite antenna to satisfy the user's need to control the switch of the satellite antenna through the control component.

[0045] The embodiments of this specification use the above control components to replace the existing antenna controller, thereby further reducing the size of the existing vehicle-mounted satellite broadband communication system and saving space in the vehicle.

[0046] Based on the above embodiments, in one embodiment of this specification, the baseband integrated device further includes: a satellite modem and a wireless access point connected to each other;

[0047] The satellite modem is connected to the satellite antenna and is used to modulate the intermediate frequency signal output by the satellite antenna into a communication signal that can be recognized by the wireless access point, and is also used to modulate the communication signal received by the wireless access point into an intermediate frequency signal that can be sent by the satellite antenna.

[0048] Specifically, the satellite modem is used to convert the communication signal received by the wireless access point into an intermediate frequency signal, and then convert the intermediate frequency signal into a microwave signal through the satellite antenna and transmit it to the communication satellite. The satellite modem is also used to convert the microwave signal sent by the communication satellite into a communication signal that can be recognized by the wireless access point. Among them, the wireless access point (wireless AP) is an access point of a wireless network, commonly known as a "hotspot". There are mainly routing switching access integrated devices and pure access point devices. The integrated device performs access and routing work, and the pure access device is only responsible for the access of the wireless client. The pure access device is usually used as a wireless network extension. Among them, the wireless AP is an access point that uses a terminal to enter the wired network to realize network communication between the terminal inside the vehicle and the satellite.

[0049] The baseband integrated device further comprises a router, two ends of which are respectively connected to the wireless access point and the satellite modem, and the router can be connected to a plurality of the wireless access points.

[0050] It is understandable that a router is also provided between the satellite modem and the wireless access point. The satellite modem can be connected to the wireless access point via the router through Ethernet.

[0051] Based on the above embodiments, in one embodiment of the present specification, the control component is also connected to the satellite modem, and the control component is also used to read the network access information and bandwidth information of the satellite modem, and display the network access information and bandwidth information in the human-computer interaction device.

[0052] Specifically, bandwidth information usually refers to the frequency bandwidth occupied by the signal, which can be the amount of data that can be transmitted in a fixed time, that is, the ability to transmit data in the transmission pipeline. When connecting to different communication satellites, the satellite modem will use different bandwidth information and network access information. The network access information is used to determine whether the corresponding communication satellite is allowed to connect to the network.

[0053] In actual applications, the control component may send the network access information and the bandwidth information to the human-computer interaction device, and display the network access information and the bandwidth information in the human-computer interaction device.

[0054] Based on the above embodiments, in one embodiment of this specification, the satellite antenna includes: a positioning device and an attitude solving component;

[0055] The positioning device is used to obtain the positioning information of the vehicle;

[0056] The attitude solving device is used to determine the pitch angle, azimuth angle and roll polarization angle of the satellite antenna at the next position by combining the position information in the positioning information acquired by the positioning device with the stored orbital data;

[0057] The control component is also connected to the attitude solving component, and is used to adjust the antenna pointing of the satellite antenna according to the pitch angle, azimuth angle and roll polarization angle of the satellite antenna at the next position.

[0058] Specifically, the on-board satellite communication system may store orbital data of multiple communication satellites. The same orbital data may correspond to different communication satellites. The orbital data represents the current position of the corresponding communication satellite. The position in the orbital data is stored based on time.

[0059] In a specific implementation process, after obtaining the vehicle's positioning information, the attitude solution component can compare the position information in the positioning information with the current position in the stored orbital data to find the satellite position information in the orbital data whose distance deviation from the position information in the positioning information is less than a preset distance threshold, wherein the satellite position information in the orbital data whose distance deviation from the position information in the positioning information is less than the preset distance threshold indicates that the communication satellite can be identified by the vehicle-mounted satellite communication system, that is, the vehicle-mounted satellite communication system can be connected to the communication satellite, and after the vehicle-mounted satellite communication system is connected to the communication satellite, the attitude solution component can determine the pitch angle, azimuth angle and roll polarization angle of the satellite antenna at the next position according to the satellite position information and the position information. Then, the control component can be used to adjust the antenna pointing of the satellite antenna according to the pitch angle, azimuth angle and roll polarization angle of the satellite antenna at the next position, so as to achieve a reliable connection between the vehicle-mounted satellite communication system and the communication satellite, thereby improving the communication efficiency of the vehicle-mounted satellite communication system.

[0060] Based on the above embodiments, in one embodiment of the present specification, the human-computer interaction device is provided with a control unit corresponding to the switching, antenna pointing, satellite signal monitoring, satellite beam switching, upgrading or fault detection operations of the satellite antenna, and the control unit is used to trigger a corresponding control signal when the user performs a preset action.

[0061] Specifically, the control unit may be a page or area in the human-computer interaction device. The preset action may be: a shaking operation, a clicking operation, a sliding operation, a dragging operation or a tapping of the screen.

[0062] For example, when the user wants to turn off the satellite antenna, he can click on the page or area corresponding to the switch of the satellite antenna. At this time, a control signal representing turning off the satellite antenna will be generated and sent to the control component. The control component will turn off the satellite antenna by disconnecting the power supply of the satellite antenna.

[0063] On the other hand, an embodiment of the present specification provides a vehicle, the vehicle is provided with the above-mentioned vehicle-mounted satellite communication system, the vehicle-mounted satellite communication system includes: a human-computer interaction device, a baseband integrated device and a satellite antenna;

[0064] The human-computer interaction device is connected to the baseband integrated device, and the human-computer interaction device is used to send a control signal triggered by a preset action to the baseband integrated device, wherein the human-computer interaction device is a terminal or a vehicle-mounted central control screen;

[0065] The baseband integrated device is connected to the satellite antenna and is used to control the satellite antenna according to the received control signal to implement switching, antenna pointing, satellite signal monitoring, satellite beam switching, upgrading or fault detection operations of the satellite antenna;

[0066] The satellite antenna is used to receive and send band communication signals of the communication satellite to achieve communication with the communication satellite.
