Description

Technical Field

[0001] The present invention belongs to the technical field of satellite communications, and in particular relates to a satellite communication receiving device. Background Art

[0002] Current satellite communication receivers utilize a dish combined with a signal receiver to receive signals. However, these devices commonly suffer from the following issues: Traditional equipment often relies on fixed installation or can only rotate the dish vertically or horizontally. During installation, the devices are susceptible to uneven ground conditions, leading to the risk of the satellite communication receiver becoming unstable and tipping over. This requires manual maintenance and results in high operational costs. Furthermore, current signal processing modes are limited, and RF channels typically only support specific frequency bands or modulation schemes. For multi-satellite, multi-band converged communication scenarios, multiple external devices must be deployed, resulting in high system redundancy and significant signal switching delays. Furthermore, current weather response is lagging, and existing devices lack the ability to locally process meteorological data, relying on external weather services to adjust reception parameters. This inevitably leads to physical damage to RF components in inclement weather. Furthermore, current protective mechanisms are weak, with most protective covers employing static covering designs, which limits signal transmission and reception flexibility. Furthermore, movable protective structures struggle to coordinate with antenna rotation in real time, leading to mechanical conflicts or obstruction of blind spots.

[0047] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0048] like Figures 1 to 7 As shown, the satellite communication receiving device includes a dish body 1, a signal receiver 2, a protective cover structure 3, a steering mechanism 4 and a base structure 5; the lower part of the steering mechanism 4 is installed inside the base structure 5, the dish body 1 is installed above the steering mechanism 4, the signal receiver 2 is installed on one side of the dish body 1, and the protective cover structure 3 is installed on one side of the steering mechanism 4;

[0049] A controller module is provided inside the base structure 5, and the signal receiver 2, protective cover structure 3, and steering mechanism 4 are all communicatively connected to the controller module; in actual use, the controller module is communicatively connected to the signal receiver, protective cover structure, and steering mechanism via a wired or wireless interface (such as RS-485 or LoRaWAN).

[0050] In a preferred embodiment of the present invention, the controller module includes a multi-modal radio frequency channel module and a meteorological data processing module;

[0051] The multimodal RF channel module is the signal processing core of the controller module, responsible for receiving, amplifying, and demodulating RF signals from the signal receiver to ensure high-quality communication. This can address common signal attenuation, interference, and multipath effects in satellite communications, improving the device's frequency band adaptability and transmission efficiency. The multimodal RF channel module enables adaptive multi-band switching (covering the 1-40 GHz range) and dynamically adjusts reception parameters through real-time analysis of signal strength, signal-to-noise ratio, and bit error rate. The multimodal RF channel module's functions include signal amplification (with a gain of up to 30 dB), filtering (bandpass filter and adaptive equalizer for noise suppression), and modulation and demodulation (supporting digital modulation such as QPSK and OFDM). Furthermore, it has anti-interference capabilities, identifying and isolating sources of electromagnetic interference (such as nearby radar or 5G base stations) to ensure signal integrity.

[0052] In a preferred embodiment of the present invention, the multi-modal radio frequency channel module is composed of a radio frequency front-end unit, a digital signal processor (DSP) unit, a multi-modal switching unit and an interface unit;

[0053] The RF front-end unit includes a low-noise amplifier (LNA), a driver amplifier, a mixer, and an automatic gain control circuit (hereinafter referred to as AGC circuit) for initial signal capture.

[0054] In a preferred embodiment of the present invention, the RF front-end unit employs a two-stage amplification structure. The first stage is a low-noise amplifier (noise figure <0.5dB), and the second stage is a driver amplifier (gain >20dB). The low-noise amplifier directly receives the RF signal (RF_in) from signal receiver 2 (i.e., feed source). The driver amplifier then performs gain amplification. The amplified output is connected to the mixer input via an impedance matching network. In actual use, the two-stage amplification structure can be connected to an input protection circuit (series ESD diodes and DC blocking capacitors) to prevent electrostatic breakdown and DC bias interference. The impedance matching network can use microstrip lines or lumped elements (LC network) to achieve 50Ω matching to reduce return loss.

[0055] In a preferred embodiment of the present invention, the mixer input receives the RF signal amplified by the LNA, the local oscillator port (LO) is connected to the phase-locked loop (PLL) synthesizer, and the output is connected to the AGC circuit through a bandpass filter.

[0056] In a preferred embodiment of the present invention, the AGC circuit is the dynamic adjustment core of the RF front end, and needs to stably output an intermediate frequency signal with an accuracy of ±0.5dB within an 80dB dynamic range;

[0057] In a preferred embodiment of the present invention, the AGC circuit includes a variable attenuator, a fixed-gain amplifier, a peak detector, a comparator, and an integrator connected in sequence, wherein the variable attenuator adopts a T-type π network circuit (composed of a PIN diode) and can adjust the attenuation by changing the diode bias voltage; the fixed-gain amplifier can compensate for the insertion loss of the variable attenuator and provide a basic gain (30dB); the peak detector adopts a logarithmic amplifier + a rectifier diode (such as AD8310) and outputs a DC voltage (V_det) proportional to the signal envelope; the comparator can compare V_det with a programmable reference voltage V_ref (from a DSP), and the error signal is sent to the integrator; the integrator can use a transconductance amplifier (OTA) to form a first-order low-pass filter with an adjustable time constant (10ns–100ms) to adapt to fast and slow signal fading.

[0058] In a preferred embodiment of the present invention, the digital signal processor unit (hereinafter referred to as the DSP unit) primarily comprises a master FPGA, a coprocessor, a cache, and external interfaces. The DSP unit can integrate an FPGA chip to run adaptive algorithms (such as LMS filtering) for real-time signal processing. The master FPGA can integrate an 8-channel 14-bit ADC / DAC supporting Direct RF sampling. The coprocessor accelerates floating-point operations, the cache stores real-time sampled data, and the external interfaces allow for expansion of ADC boards.

[0059] In a preferred embodiment of the present invention, the multi-modal switching unit mainly includes a radio frequency switch matrix and a tunable filter group, wherein the radio frequency switch matrix (which can adopt an 8×8 MEMS switch array) is used to switch to the optimal frequency band, wherein the tunable filter group includes a YIG tuned filter (3–18 GHz) and a BAW filter (18–40 GHz), and the tunable filter group switches the narrowband / wideband mode through a DC bias and supports software-configured frequency band mode (such as narrowband for voice communication and broadband for high-definition video).

[0060] In a preferred embodiment of the present invention, the interface unit provides a standard interface (such as USB 3.0 or Ethernet) to interact with the signal receiver and transmit the processed baseband signal to the user terminal.

[0061] When the signal receiver captures a satellite signal, the multi-modal RF channel module first amplifies the signal through the RF front end, and the DSP unit analyzes the spectrum characteristics. If interference (such as Doppler shift) is detected, the multi-modal switching unit automatically switches to the optimal frequency band and adjusts the steering mechanism through controller feedback to optimize the dish's orientation. The entire process takes less than 100ms, with a latency of less than 5ms, meeting real-time communication requirements.

[0062] In a preferred embodiment of the present invention, a meteorological data processing module utilizes real-time meteorological data to optimize system performance, prevent weather-related failures (such as rain fade or strong winds), and enhance device reliability in outdoor environments. This module not only processes local meteorological data but also integrates satellite remote sensing information to enable predictive maintenance. The module collects, analyzes, and responds to meteorological parameters, including temperature, humidity, wind speed, and precipitation. By modeling the impact of weather on RF signals, it dynamically adjusts signal reception parameters and physical protection. For example, during heavy rain, the module can trigger the closure of protective shields or adjust the steering mechanism angle to prevent signal interruption.

[0063] The meteorological data processing module consists of a three-layer architecture consisting of a data acquisition layer, a processing layer, and an execution layer;

[0064] The data acquisition layer: integrates multiple sensors (temperature and humidity sensor, three-dimensional ultrasonic anemometer, optical rain gauge and air pressure sensor, etc.) installed on the protective cover structure 3 and connected to the controller through the I2C bus; at the same time, it is connected to external data sources (such as meteorological satellite API or Internet weather service).

[0065] The temperature and humidity sensor, SHT85, is installed on protective cover structure 3 and has a measurement range of -40°C to 125°C, 0% to 100% RH, and an accuracy of ±0.2°C / ±1.5% RH. A three-dimensional ultrasonic anemometer uses the time difference method to measure wind speed (0-60 m / s) and direction (0-360°) with a resolution of 0.1 m / s. An optical rain gauge uses infrared beam scattering to detect precipitation type (rain / snow / hail) and intensity (0-200 mm / h), supporting particle size classification (0.3-5 mm). A BMP388 pressure sensor is used to predict short-term weather changes. Each sensor type is configured with a master / slave dual node, transmitting data in parallel via the I²C bus and SPI bus. If the master node fails, it automatically switches to the backup node, achieving a data loss rate of less than 0.1%.

[0066] External data sources include satellite weather data, which uses L-band receivers to analyze cloud maps and lightning location data from meteorological satellites in real time, with an update frequency of 5 minutes. External data sources also include internet weather services that integrate RESTful APIs (such as OpenWeatherMap and NOAA), providing 72-hour forecasts in JSON format and using CRC checksums to ensure data integrity.

[0067] Processing layer: Based on an embedded microprocessor (such as ARM Cortex-M7), it runs a meteorological algorithm library to achieve data fusion and feature extraction.

[0068] Among them, the main control chip of the processing layer is the ARM Cortex-M7+NPU coprocessor, which supports floating-point operation acceleration and parallel task scheduling; the storage unit of the processing layer is 1GB LPDDR4+8MB Flash.

[0069] When running the meteorological algorithm library to implement data fusion and feature extraction, real-time risk prediction can be achieved. Real-time risk prediction includes precipitation prediction and strong wind prediction. Precipitation prediction is based on the LSTM neural network analyzing local sensor time series data to predict the probability and intensity of precipitation in the next 10 minutes (error rate <15%). Strong wind prediction is based on calculating the wind speed variance and turbulence intensity index to determine the risk of sudden gusts (threshold: wind speed change rate >3m / s).

[0070] Execution layer: Generates control instructions, such as adjusting the opening and closing of the protective cover or adjusting the motor of the steering mechanism through PWM signals.

[0071] Among them, when generating and issuing control instructions, it is possible to control the protective cover structure, compensate for special agencies, and control the protective cover structure, including:

[0072] Opening and closing degree adjustment: It can generate a PWM duty cycle signal (0~100%) according to the precipitation intensity, drive the stepper motor (0.9° step angle) to control the expansion angle of the protective cover body, and the minimum adjustment step is 0.1°.

[0073] Emergency closure: When hail (particle size > 5mm) is detected, a full closure command is triggered (response time < 2 seconds).

[0074] Steering mechanism compensation includes:

[0075] Anti-wind deflection: The wind load compensation angle (Δθ=K_p×wind speed²) is calculated through the PID algorithm, and the steering mechanism is driven to fine-tune the pot body posture (adjustment accuracy ±0.05°).

[0076] Avoidance rules: In thunderstorms, keep the pot in a horizontal position (safety posture) to avoid damage from lightning strikes.

[0077] The system also provides position feedback for the protective cover, using a magnetic encoder (17-bit resolution) to monitor the opening and closing status of the cover in real time. Errors greater than 1° trigger recalibration. Motor current is also monitored, shutting off power and switching to the backup motor channel in the event of overcurrent (>2A) or stall. A supercapacitor (10F) is also included as an emergency power source to ensure the execution of critical commands (such as closing the protective cover during heavy rain).

[0078] In a preferred embodiment of the present invention, the meteorological data processing module continuously monitors environmental data (sampling rate 10Hz). The processing layer analyzes real-time input (e.g., wind speed >10m / s) and combines it with historical data to predict risk (e.g., probability of precipitation in the next 10 minutes). If a risk threshold is exceeded, the controller is notified to initiate a response: for example, instructions are sent to the protective cover structure to strengthen the seal or the steering mechanism to avoid the wind direction. Simultaneously, meteorological data is shared with the RF channel module to optimize frequency band selection.

[0079] The weather data processing module integrates local sensors with global weather databases (such as NOAA data), improving accuracy by 30%, reducing weather-related outages by 50%, extending device life (automatic shield protection), and supporting environmental monitoring.
