[0024] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0025] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0026] The BeiDou satellite navigation system is an independently developed and independently operated global satellite navigation system that provides military and civilian users with services such as rapid positioning, real-time navigation, and precise timing. Short message satellite communication combines text messages and navigation, and is a unique service that distinguishes the BeiDou satellite navigation system from other major navigation and positioning systems in the world.

[0027] The data link and bandwidth of Beidou communication are relatively limited. At present, the mainstream data transmission mode of Beidou communication is single-machine single-card (such as supporting data transmission of about 100 bytes). However, during the Beidou short message communication process, a large amount of Beidou short message data may be transmitted in a short time. The bandwidth of the short message communication module in the traditional solution is limited, which will lead to long transmission time and poor transmission reliability of Beidou short message data.

[0028] In response to the above problems, the present application provides a terminal system supporting satellite communication, including: multiple communication modules, all supporting data transmission based on Beidou short messages; a control node, which is connected to multiple communication modules and is used to control multiple communication modules to transmit data with the Beidou satellite system. In Beidou short message communication, short-term large data transmission may occur. In response to this situation, this solution stacks multiple communication modules to achieve large bandwidth, low latency, and high reliability of Beidou short message data transmission.

[0029] Combined with the following Figure 1 The terminal system supporting satellite communication in the embodiment of the present application is described in detail. Figure 1 As shown, the terminal system 100 supporting satellite communication may include multiple communication modules 110 and a control node 120 .

[0030] The multiple communication modules 110 all support data transmission based on Beidou short messages. The multiple communication modules 110 may include one or more communication modules based on unidirectional communication cards and / or one or more communication modules based on bidirectional communication cards.

[0031] It should be noted that, since multiple communication modules 110 can be used for data transmission with a BeiDou satellite system (such as the BeiDou-3 satellite system), each communication module can also be referred to as a BeiDou-3 communication unit.

[0032] The control node 120 is connected to the multiple communication modules 110 and is used to control the multiple communication modules 110 to perform data transmission with the Beidou satellite system.

[0033] In some implementations, the control node 120 may be a general purpose processor or a dedicated processor. For example, the control node 120 may be a central processing unit (CPU). Alternatively, the control node 120 may also be other general purpose processors, digital signal processors (DSP), application specific integrated circuits (ASIC), field programmable gate arrays (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The control node 120 may be a microprocessor or the control node 120 may also be any conventional processor, etc.

[0034] In some implementations, the control node 120 is used to control the multiple communication modules 110 to transmit data with the Beidou satellite system according to at least one of the following: the type of communication card used by the multiple communication modules 110; the communication frequency of the multiple communication modules 110; the size of the Beidou short message allowed to be transmitted by the multiple communication modules 110; the available status of the multiple communication modules 110; the amount of data to be transmitted. In other words, the control node 120 can adaptively select the corresponding target communication module from the multiple communication modules 110 to broadcast and receive data with the Beidou satellite system according to the available status of the communication module, the type of communication card, the communication capacity (the size of the Beidou short message allowed to be transmitted), etc.

[0035] For example, the control node 120 can be used to control multiple communication modules 110 to perform data transmission with the Beidou satellite system according to the type of communication card used by the multiple communication modules 110. Among them, the type of communication card used by the multiple communication modules 110 may include a unidirectional communication card (which can be referred to as a unidirectional card) and a bidirectional communication card (which can be referred to as a bidirectional card). A communication module based on a unidirectional communication card (which can be referred to as a unidirectional communication module) can support sending Beidou short message data to the Beidou satellite system, but does not support receiving Beidou short message data sent by the Beidou satellite system. A communication module based on a bidirectional communication card (which can be referred to as a bidirectional communication module) can support sending Beidou short message data to the Beidou satellite system, and can also support receiving Beidou short message data sent by the Beidou satellite system.

[0036] As an example, if the user only needs to send Beidou short message data to the Beidou satellite system, the control node 120 can select a communication module based on a unidirectional communication card (i.e., a target communication module) to transmit data with the Beidou satellite system; as another example, if the user needs to transmit and receive data with the Beidou satellite system, the control node 120 can select a communication module based on a bidirectional communication card (i.e., a target communication module) to transmit data with the Beidou satellite system.

[0037] For another example, the control node 120 can be used to control multiple communication modules 110 to transmit data with the Beidou satellite system according to the communication frequency of the multiple communication modules 110. The communication frequency of each communication module may refer to the time interval between the transmission of two Beidou short messages. For example, if the communication module communicates based on a one-way communication card, the communication frequency of the communication module may be in the second level; if the communication frequency is 1 second, that is, the communication module based on the one-way communication card can send a Beidou short message in 1 second. For another example, if the communication module communicates based on a two-way communication card, the communication frequency of the communication module may be in the minute level; if the communication frequency is 1 minute, that is, the communication module based on the two-way communication card can send a Beidou short message in 1 second.

[0038] As an example, if the user needs a higher communication frequency (such as the communication frequency requires seconds), the control node 120 can select a unidirectional communication module (i.e., the target communication module) from multiple communication modules 110 to transmit data with the Beidou satellite system; as another example, if the user needs a lower communication frequency (such as the communication frequency requires minutes), the control node 120 can select a bidirectional communication module (i.e., the target communication module) from multiple communication modules 110 to transmit data with the Beidou satellite system.

[0039] For another example, the control node 120 can be used to control multiple communication modules 110 to transmit data with the Beidou satellite system according to the size of the Beidou short message allowed to be transmitted by the multiple communication modules 110. Among them, the size of the Beidou short message allowed to be transmitted by the communication module can refer to the information capacity of the Beidou short message allowed to be transmitted by the communication module in a single time. For example, the size of the Beidou short message allowed to be transmitted by the communication module based on the unidirectional communication card can be 100 bytes. For another example, the size of the Beidou short message allowed to be transmitted by the communication module based on the bidirectional communication card can be 200, 400 or 900 bytes, etc.

[0040] As an example, if the size of the Beidou short message is less than the first threshold, the control node 120 can select a unidirectional communication module (i.e., a target communication module) from a plurality of communication modules 110 to transmit data with the Beidou satellite system; as another example, if the size of the Beidou short message is greater than or equal to the first threshold, the control node 120 can select a bidirectional communication module (i.e., a target communication module) from a plurality of communication modules 110 to transmit data with the Beidou satellite system. Among them, the first threshold can be set according to demand, and this application does not make specific restrictions on this.

[0041] For another example, the control node 120 can be used to control multiple communication modules 110 to transmit data with the Beidou satellite system according to the available status of multiple communication modules 110. Among them, the available status of the communication module can refer to whether the communication with the Beidou satellite system is currently supported. For example, when the communication module is damaged, it does not support communication with the Beidou satellite system, and the communication module is in an unavailable state; for another example, when the communication module is within the interval duration of the communication frequency of the communication module, it does not support communication with the Beidou satellite system, and the communication module is in an unavailable state; as an example, if the communication frequency of the communication module is 1 minute, the communication module needs to wait for one minute to transmit the next Beidou short message after transmitting a Beidou short message, and within the one-minute duration between the transmission of two short messages, the communication module is in an unavailable state. It should be understood that under other normal circumstances, the communication module is in an available state.

[0042] As an example, the control node 120 may control a communication module in an available state (ie, a target communication module) among the plurality of communication modules 110 to perform data transmission with the BeiDou satellite system.

[0043] For another example, the control node 120 may be used to control the multiple communication modules 110 to perform data transmission with the Beidou satellite system according to the amount of data to be transmitted. The amount of data to be transmitted is related to the data transmission requirements of the user, and the amount of data to be transmitted may be, for example, 300 bytes, 1000 bytes, etc., and this application does not impose any specific restrictions on this.

[0044] As an example, if the amount of data to be transmitted is greater than the second threshold, the control node 120 can select a one-way communication module and a two-way communication module combination (i.e., a target communication module) from a plurality of communication modules 110 to transmit data with the Beidou satellite system; if the amount of data to be transmitted is less than or equal to the second threshold, the control node 120 can select a one-way communication module or a two-way communication module combination from a plurality of communication modules 110 to transmit data with the Beidou satellite system. Among them, the second threshold can be set according to demand, and this application does not make specific restrictions on this.

[0045] It should be noted that the various influencing factors for controlling the data transmission between multiple communication modules 110 and the Beidou satellite system can be combined. For example, the control node 120 can be used to select a target communication module from multiple communication modules 110 for data transmission with the Beidou satellite system according to the data amount of the data to be transmitted and the communication frequency of the multiple communication modules 110; for another example, the control node 120 is used to select a target communication module from multiple communication modules 110 according to the data amount of the data to be transmitted, the communication frequency of the multiple communication modules 110 and the available status of the multiple communication modules 110. The present application does not impose any specific restrictions on this.

[0046] It should be noted that the communication module based on the unidirectional communication card has a higher transmission frequency (the communication frequency of the communication module based on the unidirectional communication card can be in the seconds), and a smaller transmission bandwidth (such as the size of the Beidou short message allowed to be transmitted by the communication module based on the unidirectional communication card can be 100 bytes); the communication module based on the bidirectional communication card has a lower transmission frequency (the communication frequency of the communication module based on the bidirectional communication card can be in the minutes), and a larger transmission bandwidth (such as the size of the Beidou short message allowed to be transmitted by the communication module based on the bidirectional communication card can be 200, 400 or 900 bytes, etc.).

[0047] In some implementations, the multiple communication modules 110 may be used to send indication information to the control node 120 according to the communication frequencies of the multiple communication modules 110; wherein the indication information is used to indicate the available status of the multiple communication modules 110. It should be understood that in the embodiment of the present application, the control node 120 may also be used to determine the available status of the multiple communication modules 110 according to the communication frequencies of the multiple communication modules 110. However, by having each communication module determine its own available status and report it, the control logic of the control node 120 can be simplified.

[0048] In some implementations, see Figure 2The plurality of communication modules 110 include at least one of a first type of communication module 111 and a second type of communication module 112. The first type of communication module 111 may be a communication module based on a one-way communication card, and the first type of communication module 111 may communicate based on the one-way communication card; the second type of communication module 112 may be a communication module based on a two-way communication card, and the second type of communication module 112 may communicate based on the two-way communication card.

[0049] In some implementations, the plurality of communication modules 110 may all be first-class communication modules; in other implementations, the plurality of communication modules 110 may all be second-class communication modules; of course, the plurality of communication modules 110 may also include at least one first-class communication module and one second-class communication module. This application does not make specific restrictions.

[0050] In some implementations, the first type of communication module 111 may include one or more communication modules based on a unidirectional communication card; the second type of communication module 112 may include one or more communication modules based on a bidirectional communication card.

[0051] In some implementations, considering that the communication of the second type of communication module 112 is more complex and has a higher communication cost, during data transmission, the control node 120 may preferentially use the first type of communication module 111 for data transmission, which helps to reduce the complexity of communication and reduce the communication cost.

[0052] In some implementations, after the terminal system 100 supporting satellite communication is powered on, multiple communication modules 110 may send registration information to the control node 120, and the registration information includes the inherent communication characteristics (such as communication type, communication cycle) of the multiple communication modules 110, so that the control node 120 can quickly understand the multiple communication modules. As an example, the control node 120 is also used to: before controlling the multiple communication modules 110 to transmit data with the Beidou satellite system, receive the registration information of the multiple communication modules 110, and the registration information is used to indicate at least one of the following information: the type of pass card used by the multiple communication modules 110; the communication frequency of the multiple communication modules 110; the size of the Beidou short message allowed to be transmitted by the multiple communication modules 110.

[0053] In some implementations, the control node 120 is a vehicle-mounted controller, and the vehicle-mounted controller is connected to the plurality of communication modules 110 via a CAN bus communication.

[0054] It should be understood that when the control node 120 is connected to multiple communication modules 110 via the CAN bus, theoretically the control node 120 is connected to a maximum of 255 communication modules.

[0055] It should be noted that when the communication module meets the communication reporting requirements, the communication request can be reported to the control node 120. For example, after the length of time after the communication module sends a Beidou short message data is greater than the communication frequency of the communication module, it can be considered that the communication module meets the communication reporting requirements (that is, the communication module is in an available state), and at this time, a communication request can be reported to the control node 120, requesting to use the communication module to transmit data with the Beidou satellite system.

[0056] According to the above description, it can be seen that the terminal system in the embodiment of the present application may include: multiple communication modules 110, all supporting data transmission based on Beidou short messages; control node 120, connected to multiple communication modules 110, for controlling multiple communication modules 110 to transmit data with Beidou satellite system. In Beidou short message communication, short-term large data volume transmission may occur. In view of this situation, this solution stacks multiple communication modules 110, thereby achieving large bandwidth, low latency and high reliability of Beidou short message data transmission.

[0057] The present application also provides a vehicle, see Figure 3 The vehicle 300 includes any type of satellite communication supporting terminal system 100 described above. The vehicle 300 may be any type of intelligent driving vehicle, and this application does not impose any specific limitation on this.

Figure 4 The method embodiment of the present application is described in detail. It should be understood that the description of the method embodiment corresponds to the description of the terminal system embodiment, so the parts not described in detail can refer to the previous terminal system embodiment.

The method is applied to a terminal system supporting satellite communication, the terminal system includes multiple communication modules and a control node, the control node is connected to the multiple communication modules, the multiple communication modules all support data transmission based on Beidou short messages, the communication modules include a first type of communication module and a second type of communication module, the first type of communication module communicates based on a unidirectional communication card, and the second type of communication module communicates based on a bidirectional communication card; the data transmission method 400 may include step S410.

[0060] In step S410, according to the target information, the control node is used to select a target communication module from the multiple communication modules to transmit data with the Beidou satellite system; the target information includes at least one of the following: the communication frequency requirement of the data to be transmitted is in seconds; the communication frequency requirement of the data to be transmitted is in minutes; the size of the Beidou short message is less than a first threshold; the size of the Beidou short message is greater than or equal to the first threshold; the data volume of the data to be transmitted is greater than a second threshold.

[0062] Optionally, the method further includes: using the multiple communication modules to send indication information to the control node according to the communication frequencies of each of the multiple communication modules; wherein the indication information is used to indicate the available status of the multiple communication modules.

[0063] Optionally, the method further includes: during the data transmission process, using the control node to preferentially use the first type of communication module for data transmission.
