[0023] With the development of intelligent vehicles, the integration level of vehicle-mounted terminals is also increasing. However, the integration level of Tiantong satellite terminals is relatively low, resulting in large size of Tiantong satellite terminals. Furthermore, this leads to low deployment efficiency of Tiantong satellite terminals in vehicles.

[0024] In response to the above problems, the present application provides a Tiantong satellite terminal, including: a call antenna interface for connecting to a call antenna outside the Tiantong satellite terminal; a Tiantong satellite module and a Bluetooth module, the Tiantong satellite module is connected to the Bluetooth module, and the Tiantong satellite module is connected to the call antenna through the call antenna interface; an MCU, connected to the Bluetooth module, for controlling the Bluetooth module to establish a connection with the Tiantong satellite through the Tiantong satellite module and the call antenna; the Bluetooth module is connected to the vehicle-mounted voice module outside the Tiantong satellite terminal to realize a voice call between the vehicle-mounted voice module and the Tiantong satellite. This solution mainly realizes the voice call function of the Tiantong satellite by integrating the Tiantong satellite module, the Bluetooth module and the MCU in a box. Since the Tiantong satellite module, the Bluetooth module and the MCU are integrated in a box, the demand for installation space is reduced, thereby improving the deployment efficiency of the Tiantong satellite terminal in the vehicle. The Tiantong satellite terminal in the embodiment of the present application is introduced in detail below with reference to the accompanying drawings.

[0025] Figure 1 A Tiantong satellite terminal is provided in the embodiment of the present application. The Tiantong satellite terminal in the embodiment of the present application can be applied to a vehicle, which can be an electric vehicle, a fuel vehicle or a hybrid vehicle, etc., and the present application does not make any specific restrictions on this. Figure 1 The Tiantong satellite terminal 100 may include a call antenna interface 110 , a Tiantong satellite module 120 , a Bluetooth module 130 and a micro control unit (MCU) 140 .

[0026] The communication antenna interface 110 is used to connect to a communication antenna outside the Tiantong satellite terminal 100. The communication antenna may include one or more antennas. The communication antenna may be a vehicle-mounted antenna, such as a whip antenna or a stealth antenna.

[0027] Continue to see Figure 1 The Tiantong satellite module 120 is connected to the Bluetooth module 130. The Tiantong satellite module 120 includes a Tiantong satellite baseband chip. The Tiantong satellite module 120 is connected to the communication antenna via the communication antenna interface 110. The MCU 140 is connected to the Bluetooth module 130. For example, the Tiantong satellite module 120 and the Bluetooth module 130 can be connected via a universal asynchronous receiver / transmitter (UART) serial port.

[0028] In some implementations, the MCU 140 is used to control the Bluetooth module 130 to establish a connection with the Tiantong satellite through the Tiantong satellite module 120 and the call antenna; the Bluetooth module 130 is connected to the vehicle-mounted voice module outside the Tiantong satellite terminal 100, thereby forming a voice data channel between the Tiantong satellite and the vehicle-mounted voice module, and then based on this voice data channel, a voice call (such as an emergency call) function can be realized between the vehicle-mounted voice module and the Tiantong satellite.

[0029] In some implementations, the vehicle-mounted voice module may refer to a module configured in the vehicle for voice calls, such as a microphone / speaker module.

[0030] In some implementations, the MCU 140 is connected to the Tiantong satellite module 120. For example, the MCU 140 and the Tiantong satellite module 120 can be connected via a UART serial port. The MCU 140 is configured to send a first control instruction to the Tiantong satellite module 120. The first control instruction is configured to control data transmission between the Tiantong satellite module 120 and the Tiantong satellite.

[0031] The embodiments of the present application do not impose specific restrictions on the type of the first control instruction. For example, the first control instruction may be an initialization instruction, in which case the first control instruction can be used to set the data transmission parameters of the Tiantong satellite module 120, such as baud rate (transmission rate), data bit length, number of stop bits, check mode, etc.; for another example, the first control instruction may be a start data transmission instruction, in which case the first control instruction can be used to control the start of the data transmission process of the Tiantong satellite module 120; for another example, the first control instruction may be an end data transmission instruction, in which case the first control instruction can be used to control the stop of the transmission process, release resources, or enter a low power consumption mode after the data transmission is completed.

[0032] In some implementations, the MCU 140 is further configured to receive a communication log (also referred to as an operation log) of the Tiantong satellite module 120 to monitor the operation status of the Tiantong satellite module 120 .

[0033] In some implementations, the MCU 140 is further configured to send a second control instruction to the Bluetooth module 130 , where the second control instruction is configured to control voice data transmission between the Bluetooth module 130 and the Tiantong satellite.

[0034] The embodiments of the present application do not impose any specific restrictions on the type of the second control instruction. For example, the second control instruction may be an initialization instruction, in which case the second control instruction may be used to set the voice data transmission parameters of the Bluetooth module 130, such as the baud rate (transmission rate), voice data bit length, number of stop bits, check mode, etc.; for another example, the second control instruction may be an instruction to start voice data transmission, in which case the second control instruction may be used to control the voice data transmission process of starting the Bluetooth module 130; for another example, the second control instruction may be an instruction to end voice data transmission, in which case the second control instruction may be used to control the stop of the transmission process, release resources, or enter a low power consumption mode after completing the voice data transmission.

[0035] In some implementations, the MCU 140 is further configured to receive a communication log (also referred to as an operation log) of the Bluetooth module 130 to monitor the operation status of the Bluetooth module 130 .

[0036] In some implementations, the Tiantong satellite terminal 100 may be directly attached to a vehicle-mounted domain controller or a telematics control and management (TCAM) controller.

[0037] As can be seen from the above description, this solution mainly realizes the voice call function of Tiantong satellite by integrating Tiantong satellite module 120, Bluetooth module 130 and MCU 140 into a single box. Since Tiantong satellite module 120, Bluetooth module 130 and MCU 140 are integrated into a single box, it helps to reduce the volume of Tiantong satellite terminal 100 (i.e., reduces the installation space required), and further, it can improve the deployment efficiency of Tiantong satellite terminal 100 in the vehicle.

[0038] The following describes the embodiments of the present application in more detail with reference to specific examples. Figure 2 The present invention is intended only to help those skilled in the art understand the embodiments of the present invention, and is not intended to limit the embodiments of the present invention to the specific numerical values ​​or specific scenarios illustrated. Those skilled in the art can obviously make various equivalent modifications or changes based on the examples given, and such modifications or changes also fall within the scope of the embodiments of the present invention.

[0039] Figure 2 yes Figure 1 A more detailed structural diagram of the Tiantong satellite terminal 100 is shown in FIG.

[0040] In some implementations, see Figure 2The Tiantong satellite terminal 100 further includes a positioning antenna interface 150 and a positioning module 160. The positioning antenna interface 150 is used to connect to a positioning antenna outside the Tiantong satellite terminal 100; the positioning module 160 is connected to the positioning antenna interface 150 and is used to receive positioning signals from positioning satellites through the positioning antenna to achieve vehicle positioning.

[0041] In some implementations, the positioning antenna may include one or more antennas. The positioning antenna may be a vehicle-mounted antenna, such as a whip antenna or a stealth antenna.

[0042] In some implementations, the MCU 140 is connected to the positioning module 160, such as via a UART serial port. The MCU 140 is configured to send a third control instruction to the positioning module 160, which is configured to control data transmission between the positioning module 160 and the Tiantong satellite.

[0043] The embodiment of the present application does not impose any specific restrictions on the type of the third control instruction. For example, the third control instruction may be an initialization instruction, in which case the third control instruction may be used to set the data transmission parameters of the positioning module 160, such as the baud rate (transmission rate), data bit length, number of stop bits, check mode, etc.; for another example, the third control instruction may be a start data transmission instruction, in which case the third control instruction may be used to control the data transmission process of starting the positioning module 160; for another example, the third control instruction may be an end data transmission instruction, in which case the third control instruction may be used to control the stop of the transmission process, release resources, or enter a low power consumption mode after the data transmission is completed.

[0044] In some implementations, see Figure 2 The Tiantong satellite terminal 100 further includes a controller area network (CAN) transceiver 170. The CAN transceiver 170 is connected to the MCU 140; the MCU 140 is configured to communicate CAN network data with devices external to the Tiantong satellite terminal 100 via the CAN transceiver 170.

[0045] In some implementations, in order to improve the data transmission rate and bandwidth of the CAN network, data can be transmitted between the CAN transceiver 170 and devices outside the Tiantong satellite terminal 100 via controller area network flexible data-rate (CAN FD).

[0046] In some implementations, the CAN transceiver 170 may be used to implement physical layer communications of a CAN network.

[0047] In some implementations, see Figure 2 The Tiantong satellite terminal 100 further includes a main connector 192. The CAN transceiver 170 can communicate CAN network data with devices external to the Tiantong satellite terminal 100 via the main connector 192. For example, the CAN transceiver 170 is connected to devices external to the Tiantong satellite terminal 100 via the main connector 192 and the high / low level signal lines (e.g., CAN1_H and CAN1_L) of the CAN bus.

[0048] In some implementations, the device outside the Tiantong satellite terminal 100 can be, for example, various electronic control units (ECUs) inside a vehicle, such as an engine control unit and a transmission control unit, and this application does not make specific restrictions.

[0049] In some implementations, see Figure 2 The Tiantong satellite terminal 100 further includes a power conversion module 180. The power conversion module 180 is connected to a power supply external to the Tiantong satellite terminal 100. For example, the power conversion module 180 can be connected to a battery power source (e.g., BATT) external to the Tiantong satellite terminal 100 via a main connector 192. The power conversion module 180 can be used to convert the power supply into a regulated power supply (e.g., a 5V and / or 3.3V power supply) to supply power to the Tiantong satellite terminal 100.

[0050] In some implementations, the power conversion module 180 includes a low dropout regulator (LDO), which is used to convert the power supply into a 3.3V DC power supply and supply power to the Tiantong satellite module 120 , the Bluetooth module 130 , and the MCU 140 .

[0051] In some implementations, the power conversion module 180 also includes a direct current to direct current converter (DC-DC), which is used to convert the power supply into a 5V direct current power supply and supply power to modules in the Tiantong satellite terminal 100 that require a 5V power supply (such as the CAN transceiver 170).

[0052] In some implementations, the Tiantong satellite terminal 100 further includes a backup battery 190. The backup battery 190 is connected to the power conversion module 180 and is configured to provide backup power to the Tiantong satellite terminal 100. This means that, due to the presence of the backup battery 190, the Tiantong satellite terminal 100 will continue to operate normally even if the external power supply suddenly fails, thereby improving the stability of the Tiantong satellite terminal 100.

[0053] In some implementations, see Figure 2The Tiantong satellite terminal 100 further includes a non-volatile memory (NORFLASH) 191, which is connected to the MCU 140. For example, the non-volatile memory 191 and the MCU 140 can be connected via a serial peripheral interface (SPI). The non-volatile memory 191 is used to store communication data of the MCU 140.

[0054] In some implementations, see Figure 2 The MCU 140 can receive IO signals and pulse width modulation (PWM) signals from outside the Tiantong satellite terminal 100 through the main connector 192 to control the MCU 140 from outside the Tiantong satellite terminal 100, such as wake-up control or interrupt control, etc. This application does not impose any specific restrictions on this.

[0055] The present application also provides a vehicle, such as Figure 3 As shown, the vehicle 300 includes any type of Tiantong satellite terminal 100 mentioned above.
