Description

Technical Field

[0002] Under the background of the rapid development of cutting-edge technologies such as low-orbit constellations, Ka high-throughput satellites, and satellite Internet, the field of satellite communications is in great demand and developing rapidly, and the number of satellites in space is growing rapidly. The airborne in-motion antenna is an important part of the UAV satellite communication system and is located at the forefront of the entire communication system. Its function is to receive downlink signals from synchronous satellites during the flight of the UAV, and at the same time transmit uplink signals to the satellite, realizing the signal transceiver function between the satellite communication mobile station and the satellite.

[0003] Ka high-throughput satellites use a spot beam design, and moving antennas need to switch beams to ensure stable communications under high-speed movement. Moving antennas for low-orbit satellites also need automatic satellite tracking. This means that the modem in the drone satellite communication link system needs to exchange data with the antenna controller in real time.

[0004] UAVs have two communication links for telemetry, remote control and payload data transmission. The line-of-sight link has a high communication bandwidth and strong anti-interference ability, but a small effective radius. The satellite link has a large effective range and is not affected by terrain, but is easily interfered with, and before each flight, the cabin cover needs to be opened to configure many parameters to complete the deployment. It is particularly important to be able to configure the satellite link parameters when the satellite link is established and interfered with so that it can be automatically established and restored.

[0005] At present, most vehicle-mounted and ship-mounted antennas manually reload satellite and beam information through antenna controllers, which has poor real-time performance and makes it impossible to monitor the antenna operating status in real time. Summary of the invention

[0060] Next, the present application scheme will be described through specific embodiments in conjunction with the accompanying drawings.

[0061] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of a data exchange unit of a UAV on-the-go communication system provided in an embodiment of the present application. Figure 1 As shown, including:

[0062] The data interaction unit mainly includes a voltage conversion module, a network port module, a serial port module, a SWD module and an MCU module.

[0063] The power supply module converts DC24V into DC3.3V to power the network port module, MCU module and serial port module; the network port module is physically connected to the satellite modem through the RJ-45 interface and performs OpenAMIP command data interaction; the serial port module is physically connected to the satellite antenna controller through the RS-232 bus and performs antenna status information data interaction; the serial port module uses the RS-422 bus to complete the Modem channel information data interaction with the line-of-sight link unit, and establishes the data channel between the line-of-sight link and the satellite communication link; the SWD module completes the burning and debugging of the satellite communication data interaction method, and the MCU module performs data interaction with the network port module and the serial port module to complete the hardware platform implementation and application of the data interaction method.

[0064] The data interaction unit involves data interaction and data synchronization with multiple peripheral resources. In order to improve the real-time and rapid response capabilities of the system, an RTOS system is used to complete the hardware platform implementation of the data interaction method.

[0065] like Figure 2 As shown, the data interaction unit includes the following tasks: creating TCP tasks, data processing tasks, sky controller tasks and line-of-sight link tasks. The specific tasks and data interaction methods are as follows:

[0066] In the TCP task, the TCP connection status is first determined. If yes, the IP address information of the modem is recorded, and the IP address information is used for the subsequent TCP data encapsulation link; otherwise, wait for the modem to go online to establish a TCP connection; at this time, the data interaction unit is in TCP server mode.

[0067] The TCP task receives satellite commands and keep-alive commands according to the TCP command reception flag. The satellite command reception mainly receives the target satellite and beam information sent by the satellite modem. After the satellite command reception is completed, the satellite command reception completion flag is generated, and the satellite command is sent to the message queue; the keep-alive command reception is mainly to obtain the shortest period sent by the modem to the data unit to maintain the communication connection, and send it to the periodic timer of the data processing task; the TCP task receives the Modem channel status from the modem, generates the Modem reception flag, and sends this status information to the message queue.

[0068] The TCP task reads the corresponding instruction from the corresponding TCP message queue and sends it to the modem according to the TCP instruction sending flag; the TCP instructions mainly include antenna GPS instructions, antenna basic status instructions and Modem channel configuration instructions; the antenna GPS instructions provide location information for modem beam switching judgment, the antenna basic status instructions monitor the antenna operation status for ground satellite communication terminal users, and the Modem channel configuration instructions are mainly completed during the initial link establishment and switching of Modem channel resources when the link is interfered.

[0069] The data processing task reads satellite commands from the message queue according to the satellite command reception completion flag. Satellite command processing includes command segmentation, single command processing, and serial port data packaging. Command segmentation includes satellite single commands such as the target satellite and its beam beacon frequency and symbol rate, satellite reception polarization mode, satellite transmission polarization mode, satellite longitude, downconverter local oscillator frequency, and roll-off coefficient; single command processing is calculated according to the preset single command processing formula; serial port data packaging includes function code determination, checksum calculation, and frame header and frame tail encapsulation.

[0070] The data processing task creates a periodic timer of the corresponding period according to the keep-alive instruction in the TCP task, and sends the antenna GPS instruction sending flag to the TCP data encapsulation after the timing is completed; the TCP data encapsulation encapsulates the antenna GPS instruction, antenna basic status instruction and Modem channel configuration instruction and sends them to the message queue. The TCP data encapsulation link includes TCP application layer encapsulation, IP encapsulation and Ethernet encapsulation.

[0071] The task of the space controller is implemented by serial port DMA. According to the satellite message sending flag and antenna configuration information flag, the corresponding data is read from the message queue to the DMA sending data buffer, and sent to the antenna controller through the RS-232 bus to complete the antenna alignment, tracking and restart; the task of the space controller periodically reads the antenna basic status frame sent by the space controller from the DMA receiving buffer, on the one hand, sends the basic status frame directly to the message queue, and on the other hand, decomposes and packages the antenna basic status frame, and sends the instruction set to the TCP data encapsulation link in the data processing task by extending the OpenAMIP protocol. The extension method uses the preset antenna basic information instructions such as the antenna information instruction type and example table.

[0072] The line-of-sight link task is implemented using serial port DMA. According to the antenna basic status flag and the Modem channel status flag, the corresponding data is read from the message queue to the DMA send data buffer, and sent to the line-of-sight link unit through the RS-422 bus to complete the line-of-sight link ground terminal's monitoring of the antenna status and channel status; the line-of-sight link task reads the antenna configuration information and Modem channel configuration information uploaded by the line-of-sight link from the DMA receive buffer, and sends this information to the message queue.

[0073] See also Figure 3 , Figure 3 The following is a flow chart of a data interaction method provided in an embodiment of the present application. Figure 3 As shown, the following steps are included:

[0075] Step S302: when a TCP connection is established with the modem based on the TCP connection request, a target satellite instruction sent by the modem is received;

[0076] Step S303: receiving a communication keep-alive instruction sent by the modem, and creating a periodic timer based on the communication keep-alive instruction.

[0077] The period of the periodic timer can be set according to specific circumstances and is not limited here.

[0078] Before receiving the communication keep-alive instruction sent by the modem and creating a periodic timer based on the communication keep-alive instruction, it also includes: initiating a TCP connection request to the modem, then establishing a TCP connection with the modem based on the TCP connection request, receiving the target satellite instruction sent by the modem, then processing the target satellite instruction, generating satellite information, and sending the satellite information to the antenna controller.

[0079] Among them, the target satellite instructions include the beacon frequency and symbol rate of the target satellite, satellite receiving polarization mode, satellite transmitting polarization mode, satellite longitude, downconverter local oscillator frequency, roll-off factor, etc.

[0080] The target satellite command processing mainly includes command segmentation, single command processing and serial port data packaging, etc. The satellite single command processing formula satisfies:

[0081]

[0082] Among them, H L The L-band satellite beacon frequency required for the mobile antenna controller to change satellites and track, H Ka is the target satellite and its beam beacon frequency, B Ris the local oscillator frequency of the downconverter; Bw is the satellite beacon bandwidth required for satellite switching and tracking by the mobile antenna controller, G R is the symbol rate, α is the roll-off factor; P is the satellite polarization mode required for satellite switching and tracking by the mobile antenna controller, P R is the satellite receiving polarization mode, P T The polarization mode of satellite transmission.

[0083] Step S304: Periodically receive antenna basic status information sent by the antenna controller through a periodic timer.

[0084] Among them, the basic status information of the antenna includes the real-time longitude of the antenna, the real-time latitude of the antenna, the beacon voltage of the antenna, the star lock status of the antenna, the attitude angle information of the antenna, the zero bias information of the gyro, the carrier attitude information and the operation time of the antenna.

[0085] Step S305: Extending the OpenAMIP protocol to the antenna basic status information regularly through a periodic timer to obtain an antenna basic status instruction.

[0086] Among them, the antenna basic status instructions such as antenna information instruction types and examples obtained by extending the OpenAMIP protocol are shown in Table 1 below:

[0087] Table 1 Antenna basic status command types and examples

[0088]

[0089]

[0090] Step S306: Send the antenna basic status information to the line-of-sight link unit, and encapsulate the antenna basic status instruction into data and send it to the modem to monitor the operating status of the airborne satellite communication antenna.

[0091] like Figure 4 As shown, after sending antenna basic status information to the line-of-sight link unit, and encapsulating the antenna basic status instruction into data and sending it to the modem to monitor the operating status of the airborne satellite communication antenna, it also includes: receiving the Modem channel status sent by the modem through a periodic timer; encapsulating the Modem channel status into data, and sending the encapsulated Modem channel status to the line-of-sight link unit, so that the line-of-sight link unit makes a link interference judgment based on the encapsulated Modem channel status.

[0092] Preferably, the Modem channel information (also called Modem channel status) includes channel transmission frequency, channel reception frequency, channel transmission data rate, channel reception data rate, channel transmission power, channel transmission switch, channel reception signal-to-noise ratio and channel reception lock status, etc.

[0093] Among them, after encapsulating the Modem channel state into data and sending the encapsulated Modem channel state to the line-of-sight link unit so that the line-of-sight link unit makes a link interference judgment based on the encapsulated Modem channel state, the method further includes: if the modem fails, receiving the Modem channel configuration information sent by the line-of-sight link unit; encapsulating the Modem channel configuration information into data to obtain a Modem channel configuration instruction, and sending the Modem channel configuration instruction to the modem so that the modem switches the satellite communication channel information based on the Modem channel configuration instruction.

[0094] Preferably, the modem channel configuration information mainly includes channel transmission frequency, channel reception frequency, channel transmission data rate, channel reception data rate, channel transmission power and channel transmission switch, etc.

[0095] Data encapsulation includes serial port data encapsulation and TCP data encapsulation. Serial port data encapsulation includes function code determination, checksum calculation and frame header and frame tail encapsulation. TCP data encapsulation methods include TCP application layer encapsulation, IP encapsulation and Ethernet encapsulation.

[0096] Among them, after the Modem channel status is data encapsulated and the encapsulated Modem channel status is sent to the line-of-sight link unit so that the line-of-sight link unit makes a link interference judgment based on the encapsulated Modem channel status, it also includes: if the satellite communication antenna fails, receiving the antenna configuration information sent by the line-of-sight link unit; sending the antenna configuration information to the antenna controller so that the antenna controller executes the gyro zero bias calibration and restarts the satellite communication antenna instruction based on the antenna configuration information.

[0097] Preferably, the antenna configuration information includes restarting the antenna, gyro zero bias calibration, PID parameter configuration, beacon attenuation, etc.

[0098] This application establishes a satellite link and a line-of-sight link channel, increasing the data interaction between the dual links of the drone. Modifying the modem channel parameters and satellite antenna configuration through the line-of-sight link avoids frequent opening of the drone cabin cover for manual parameter input. When the satellite link is interfered, channel switching and antenna configuration can be performed to ensure that the drone continues to operate; and the line-of-sight link can also monitor the channel status and antenna status of the modem in real time.

[0099] In one embodiment, the method further comprises:

[0100] Send antenna GPS commands to the modem;
