Description

Technical Field

[0001] This application relates to the field of antenna control technology, and more specifically, to a method, apparatus, equipment, and medium for controlling a spaceborne active phased array antenna. Background Technology

[0002] Active phased array antennas are widely used in the field of communications as a common tool for long-distance signal transmission. Active phased array antennas achieve beam scanning by digitally or analogly controlling a beam control chip through a beam control circuit. The beam control circuit uses an FPGA or microprocessor as the control chip, along with peripheral circuitry, to communicate with the beam control chip, thereby controlling the phased array antenna to achieve beam scanning at different angles.

[0003] Existing beam control circuits typically only perform simple control functions and do not monitor the overall status of the phased array system. For example, as high-power microwave devices, phased array systems generate significant heat during operation. Furthermore, the beam control chip and peripheral circuits of the phased array antenna exhibit different current characteristics in standby and operational states. During satellite operation, it may be necessary to collect the overall operating current to observe whether the phased array antenna is functioning correctly.

[0018] It should be noted that the term "comprising" will be used in the embodiments of this application to indicate the presence of the features declared thereafter, but does not exclude the addition of other features.

[0019] Existing active phased array control circuits typically only perform simple control functions and do not monitor the status of the entire phased array system. This wastes some waiting time when handling multiple tasks and affects the beam switching time of the phased array antenna.

[0020] Based on this, the present application provides a method, apparatus, device and medium for controlling a spaceborne active phased array antenna, which will be described below through embodiments.

[0021] Example 1 To facilitate understanding of this embodiment, a method for controlling a spaceborne active phased array antenna disclosed in this application will first be described in detail. For example... Figure 1 The diagram shown is a flowchart of a control method for a spaceborne active phased array antenna. Figure 2The diagram shows another flowchart of a control method for a spaceborne active phased array antenna. This application provides a control method for a spaceborne active phased array antenna, applied to an active phased array antenna system. The active phased array antenna system includes a controller, a beam control module, an antenna array, and a status acquisition module. The method includes: S101. The first module of the controller receives the pointing angle command sent by the satellite computer, and the second module of the controller calculates the phase shift data according to the pointing angle in the pointing angle command, and sends the phase shift data to the beam control module. S102. The beam control module controls the antenna array to shift phase to the pointing angle according to the phase shift data, and starts the status acquisition module after the phase shift is completed. S103. The status acquisition module monitors the working status of the equipment corresponding to the active phased array antenna system from multiple dimensions, obtains monitoring data, and transmits the monitoring data to the controller. S104. The controller processes the monitoring data based on the second module to obtain the data processing result, and inputs the data processing result to the satellite computer through the first module to control the active phased array antenna system. In step S101, the active phased array antenna system establishes a communication link with the spaceborne computer beforehand. This communication link includes a UART asynchronous serial bus and a CAN bus, such as... Figure 3As shown, the controller of the active phased array antenna system is the Polarfire SOC, an FPGA integrating a 5-core RISC-V hard core. The hardware uses Microchip's new PolarFire series. The MPFS025T from the SOC family includes a first module and a second module. The first module is an FPGA module, and the second module is a RISC-V module. The two are connected via AXI. Through the communication link, the first module in the controller of the active phased array antenna system receives pointing angle commands sent by the satellite computer. The first module sends the pointing angle commands to the second module. The second module of the controller parses the pointing angle commands, reads the pointing angle, and calculates phase shift data based on the pointing angle. The phase shift data is a parameter for adjusting the phase of electromagnetic waves. That is, each small element in the antenna array emits electromagnetic waves with its own phase. The phase shift data tells each element how to adjust its rhythm so that the electromagnetic waves of all elements can be combined to accurately point in the target direction, realizing directional transmission or reception of signals. After obtaining the phase shift data, the second module sends the phase shift data to the first module, and the first module sends the phase shift data to the beam control module. The beam control module and the controller interact with each other via the SPI bus, that is, the phase shift data is sent to the beam control module via the SPI bus.

[0022] In a specific implementation of step S101, one embodiment is as follows: before the first module of the controller receives the pointing angle command sent by the satellite computer, it includes: S1011, the space service computer sends a power-on command to the active phased array antenna system in its initial state based on a pre-built communication link; S1012. In response to the power-on command, the active phased array antenna system switches from the initial state to the working state.

[0023] In steps S1011-S1012, the space station computer controls the active phased array antenna system to power on according to its own needs or predefined logic. When the active phased array antenna system is not powered on, it is always in a standby state, which is the initial state of the active phased array antenna system. Therefore, the space station computer sends a power-on command to the active phased array antenna system in the initial state based on a pre-built communication link, namely UART asynchronous serial bus or CAN bus. The active phased array antenna system responds to the power-on command, parses the power-on command, and executes the power-on command, thereby switching the initial state to the working state to start antenna array control.

[0024] In step S102, the beam control module uses the beam control chip ARW97420 and its peripheral amplifier circuit. It is connected to the controller via SPI and to the antenna array via an RF connector. The antenna array is composed of many small antenna elements arranged together. These elements work together to precisely control the transmission direction and coverage of electromagnetic waves, making the signal more concentrated and directional. After receiving the phase shift data sent by the controller, the antenna array is phase shifted to the pointing angle via the RF connector according to the phase shift data. After the phase shift is completed, a phase shift completion signal is fed back to the controller. The controller then starts the status acquisition module based on the phase shift completion signal. At this time, the device corresponding to the active phased array antenna system is in working state.

[0025] In step S103, based on the phase shift completion signal, the controller determines that the active phased array antenna system is in operation. The status acquisition module uses an ADS8344 analog-to-digital converter chip to convert analog voltage into digital signals. It includes a temperature acquisition module, a status detection module, and a time management module. The temperature acquisition module uses a DS2480B serial-to-single-bus chip, connected to a temperature sensor 18B20 via a single bus, to acquire the temperature at various points in the active phased array antenna system. The status detection module acquires the operating status of multiple modules in the active phased array antenna system. The time management module monitors the operating duration of the active phased array antenna system and is implemented by the FPGA module through internal logic circuits. Therefore, the status acquisition module can monitor the operating status of the corresponding equipment in the active phased array antenna system from multiple dimensions, obtaining monitoring data. This monitoring data is a collection of data acquired by the temperature acquisition module, status detection module, and time management module, and is transmitted to the controller. The first module of the controller then transmits the monitoring data to the second module for analysis and processing.

[0026] In a specific implementation of step S103, one embodiment is as follows: the status acquisition module monitors the operating status of the equipment corresponding to the active phased array antenna system from multiple dimensions, including: S1031. Based on the actual operating characteristics of the active phased array antenna system, set up multiple state monitoring dimensions for the active phased array antenna system. S1032. Based on the multiple status monitoring dimensions, set corresponding status monitoring methods to monitor the working status of the equipment corresponding to the active phased array antenna system from multiple dimensions.

[0027] In steps S1031-S1032, based on the actual operating characteristics of the active phased array antenna system, such as the fact that the phased array system, as a high-power microwave device, generates a large amount of heat during operation; the beam control chip and peripheral circuits of the phased array antenna have different currents in standby and operating states; during satellite operation, it may be necessary to collect the operating current of the entire system to observe whether the phased array antenna is working properly; and long-term continuous operation will cause the chips, circuits, and other components to continuously heat up and suffer losses, etc. Therefore, multiple status monitoring dimensions for the active phased array antenna system are set. Thus, the status monitoring dimensions include temperature, operation, and time dimensions, and corresponding status monitoring methods are set for each status monitoring dimension to monitor the operating status of the equipment corresponding to the active phased array antenna system from multiple dimensions.

[0028] In step S104, the first module of the controller receives the monitoring data and also sends the monitoring data to the second module. Based on the multi-dimensional processing of the monitoring data by the second module, a data processing result is obtained. If the data processing result indicates an anomaly, the device of the active phased array antenna system is automatically shut down based on the data processing result, and fault information is generated. The data processing result includes fault information, such as abnormal locations and abnormal data. The data processing result is fed back to the first module, and the first module inputs the data processing result to the satellite computer. The satellite computer can then perform corresponding processing based on the fault information included in the data processing result to control the active phased array antenna system. In the specific implementation of step S104, one embodiment is as follows: the state monitoring dimension includes at least the temperature dimension; The controller processes the monitoring data based on the second module to obtain data processing results, including: A1. Determine whether the temperature data of the active phased array antenna system obtained in the temperature dimension meets the temperature threshold of the detection point corresponding to the temperature data. A2. If so, then the abnormal data of the temperature dimension is determined, and the fault information corresponding to the abnormal data is generated.

[0029] In steps A1-A2, in the temperature dimension, a temperature sensor 18B20 in the temperature acquisition module is set to detect the temperature of various parts inside the active phased array antenna system. Other types of sensors can also be used to achieve temperature acquisition. As a high-power single unit, the active phased array antenna system generates a lot of heat during operation, requiring real-time temperature monitoring to ensure that the active phased array antenna system operates at a suitable temperature. This application sets corresponding temperature thresholds for multiple detection points of the active phased array antenna system. It then determines whether the temperature data of the active phased array antenna system obtained in the temperature dimension meets the temperature threshold of the corresponding detection point. If not, monitoring continues; if yes, abnormal data in the temperature dimension is identified, and fault information corresponding to the abnormal data is generated. The active phased array antenna system then automatically shuts down.

[0030] In the specific implementation of step S104, another embodiment exists in which the status monitoring dimension includes at least the operational dimension. The controller processes the monitoring data based on the second module to obtain data processing results, including: B1. Pre-set the data ranges corresponding to various standard electrical quantities of multiple sensors in the aforementioned operating dimension; B2. Determine whether the electrical quantity data corresponding to multiple standard electrical quantities meet the corresponding data range in order to identify abnormal data.

[0031] In steps B1-B2, within the operational dimension, various standard electrical quantities of multiple sensors are pre-set with corresponding data ranges. These standard electrical quantities reflect the operating status of the active phased array antenna system, specifically including key states such as circuit voltage and current, including the system's power supply voltage, FPGA operating voltage, beam chip operating voltage, and operating current. The electrical quantity data corresponding to these standard electrical quantities are primarily detected by various voltage and current sensors in the status detection module. Real-time data of various electrical quantities in the active phased array antenna system is detected based on these sensors, and it is determined whether the electrical quantity data corresponding to the standard electrical quantities meets the corresponding data range. This data range indicates an abnormal operating status, thus identifying abnormal data. If any electrical quantity data is abnormal, the active phased array antenna system is considered abnormal, and fault information is generated based on this abnormal data and sent to the satellite computer. The active phased array antenna system then automatically shuts down.

[0032] In the specific implementation of step S104, there is another embodiment in which the state monitoring dimension includes at least the time dimension; The controller processes the monitoring data based on the second module to obtain data processing results, including: C1. Obtain the operating time data of the active phased array antenna system by monitoring the operating time of the time dimension; C2. If the working duration data reaches the preset standard working duration, control the active phased array antenna system to automatically switch the working state.

[0033] In steps C1-C2, in the time dimension, under normal temperature and operating conditions, the time management module performs real-time counting based on the FPGA's internal time management module to obtain the operating time data of the active phased array antenna system. If the operating time data reaches the preset standard operating time, the active phased array antenna system is controlled to automatically switch its operating state. If no standby command is received before the specified operating time is reached, the active phased array antenna system automatically controls the active phased array antenna system to switch its operating state to standby state when the standard operating time is reached, and returns the standby signal corresponding to the standby state to the satellite computer.

[0034] In the specific implementation of step S104, another embodiment exists: the controller processes the monitoring data based on the second module to obtain the data processing result, and further includes: D1. The active phased array antenna system receives a standby command sent by the satellite computer during the standard operating period. D2. Based on the standby command, the active phased array antenna system switches from the working state to the standby state.

[0035] In steps D1-D2, the active phased array antenna system receives a standby command from the satellite computer during the standard operating time. That is, within the standard operating time, the active phased array antenna system receives a standby command from the satellite computer in normal working state. Based on the standby command, the active phased array antenna system switches from working state to standby state and stops controlling the antenna array. If no standby command is received before the specified working time is reached, the device will automatically enter standby state when the specified time is reached and return the standby signal corresponding to the working state to the satellite computer for corresponding processing.
