Description

Technical Field

[0001] This invention relates to the field of communication management technology, specifically to a rapidly deployable laser ground receiving system. Background Technology

[0002] In the development of modern satellite communication, the requirements for the management efficiency of ground receiving systems are becoming increasingly stringent. With the rapid development of satellite technology, the amount of data generated by satellite detection is growing exponentially. Traditional microwave communication ground stations can no longer meet the demand in terms of data transmission rate. Satellite-to-ground communication, with its significant advantages such as high bandwidth, low latency, and good security, has become a key technology for solving the problem of ultra-high-speed transmission of massive amounts of data.

[0003] Traditional solutions employ methods such as the construction of fixed ground stations and mobile vehicle-mounted ground stations. Fixed ground station construction involves screening candidate areas using satellite remote sensing data, such as arid, low-cloud, and low-electromagnetic-interference regions, conducting on-site geological drilling to assess foundation bearing capacity, and deploying meteorological stations for continuous monitoring for more than one year to acquire data such as wind speed and precipitation. Vehicle-mounted ground station construction incorporates an ATP (acquisition, tracking, and targeting) system, transceiver modules, and data processing units to achieve the purpose of deploying laser ground receivers.

[0004] However, traditional ground receiving systems suffer from numerous problems in deployment and management: on the one hand, the construction of fixed ground stations relies on manual experience for equipment installation quality and cable connection reliability, making it impossible to quantitatively evaluate and monitor through data-driven methods, thus creating potential performance risks; on the other hand, while mobile vehicle-mounted ground stations offer some flexibility, they lack an integrated data management system to achieve high-precision measurement and intelligent monitoring of critical processes such as pointing and link establishment, affecting the rapid aiming, acquisition, and tracking performance of satellite-to-ground communication; existing systems lack data-based link establishment monitoring and adaptive adjustment capabilities, resulting in poor communication stability and reliability; and in terms of pointing adjustment, the lack of effective data processing and monitoring methods makes it difficult to achieve ideal accuracy. Therefore, it is crucial to develop a ground receiving system that can be rapidly deployed and possesses high-precision data-based management and monitoring capabilities as well as efficient and intelligent operation and maintenance capabilities. Summary of the Invention

[0026] This embodiment requires specific explanation of the hardware equipment required for the ground receiving system, including but not limited to optical components (such as telescopes and fast reflectors), sensors (such as laser rangefinders and GPS modules), environmental sensors, control equipment, gyroscopes, accelerometers, etc., and has passed power-on testing, signal connectivity verification, and other processes to ensure that all devices work together; the preset API interfaces include Ethernet, CAN, RS485, etc.

[0027] This embodiment requires specific explanation of the following: Equipment assembly data includes the actual on-site installation location of the equipment, installation coordinates relative to the design values, data transmission bandwidth between equipment, end-to-end equipment communication delay, and packet loss rate during data transmission; Equipment pointing data includes the initial pointing coordinates of the equipment and the design pointing coordinates, the number of times the pointing coordinate error is within the allowable range, the total number of tests, the actual distance between the fixed end and the mobile end, the pixel coordinates of the center of the light spot image, and the pixel coordinates of the actual center of the light spot; Ground receiving link establishment data includes the theoretical minimum link establishment process triggering to completion time, the actual link establishment time from initiation to successful link establishment, the actual receiver signal strength, the preset minimum signal strength for successful link establishment, the ideal signal strength, the normal working time of the link, and the recovery time after the link is interrupted.

[0028] Please see Figure 2 As shown, this embodiment requires specific explanation as follows: the ground receiving equipment assembly module includes an equipment assembly data acquisition unit, an equipment pointing data acquisition unit, and a ground receiving link establishment data acquisition unit; the equipment assembly data acquisition unit is used to acquire equipment assembly data, the equipment pointing data acquisition unit is used to process and acquire equipment pointing data, and the ground receiving link establishment data acquisition unit is used to acquire ground receiving link establishment data.

[0029] Ground receiving equipment assembly management module: This module processes the equipment assembly data, calculates the equipment installation accuracy management index and the interface communication stability management index, integrates them to obtain the equipment assembly quality management index, and transmits it to the remote monitoring and maintenance module. The module includes the following steps:

[0030] S1.1: First, use a laser rangefinder to measure the deviation between the actual three-dimensional coordinates (x, y, z) of the equipment's installation location on site and the design installation coordinates (x0, y0, z0). Ensure all coordinate units are consistent to obtain the deviation coefficient η(zb). Δxmax Δy max and Δz max Let x, y, and z represent the maximum deviation thresholds in the x, y, and z directions, respectively, where n is the number of devices and i is the i-th device. This yields the device installation accuracy management index Q1, where Q1 = 1 / [1 + η(zb)]. Then, using network analysis equipment (such as a network analyzer or communication latency testing tool), the data transmission bandwidth bw, end-to-end device communication latency dL, and packet loss rate db between devices via a preset API interface are monitored to obtain the interface communication stability management index Q2. bw0, dL0, and db0 represent the design bandwidth, the maximum allowable communication delay, and the maximum allowable packet loss rate, respectively.

[0031] S1.2: The equipment installation accuracy management index and the interface communication stability management index are integrated to obtain the equipment assembly quality management index Q, Q=a1×Q1+a2×Q2, where a1 and a2 represent the corresponding weights, which can be obtained by fitting based on historical data using the entropy weight method, for example a1=0.7 and a2=0.3;

[0032] Intelligent pointing management module: This module processes device pointing data, performing initial pointing accuracy management, real-time error correction management, and spot recognition management. It then integrates the results of each management step to obtain intelligent pointing quality management indicators, which are then transmitted to the remote monitoring and maintenance module. The process includes the following steps:

[0033] S2.1: Initial pointing accuracy management: Obtain the azimuth angle Az and pitch angle E1 of the equipment (e.g., gyroscope angle, accelerometer position) in the ground receiving equipment module through attitude sensors, and compare them with the design azimuth angle Az. des and pitch angle El des By comparison, the pointing error Δθ is obtained. The unit is radians or degrees; simultaneously, the deviation |Δd| between the measured distance at the fixed end and the actual distance at the moving end is obtained using a laser rangefinder. If Δθ ≤ the corresponding threshold Δθ th (e.g., 0.1 rad) and |Δd|≤Δd max Δd max If the error is within the maximum allowable range, the calibration passes; otherwise, an alarm is triggered and recalibration is performed. The number of successful calibrations (N) and the total number of tests (TN) are recorded to obtain the initial pointing accuracy management index (P1). ;

[0034] S2.2: Real-time Error Correction Management: Adjusts the pointing mechanism based on the pointing error alarm signal, and outputs the correction amount azimuth angle Az. re and pitch angle El re Calculate the corrected residual Δθ re , ΔAz=|Az-Az des |,ΔEl=|El-El des | and record the corrected residual Δθ re ≤ the corresponding threshold Δθ re th The number of times N va The real-time error correction management index P2 is obtained, where P2 = N. va / TN;

[0035] S2.3: Spot Recognition and Management: Using a CCD camera under n1 different conditions (such as different lighting conditions, different satellite signal strengths, etc.), n2 sets of spot images are acquired for each condition, and the pixel coordinates (u) of the center of the spot image are extracted. I ,v I The image is then compared with the actual center pixel coordinates (u0, v0) of the light spot to obtain the center pixel error E of the light spot for each image. I , The center pixel error E of the light spot in n1×n2 images I The average pixel error μ(E) is obtained by averaging. I ), to obtain the spot recognition accuracy P3, P3=exp[-(μ(E I ) / (E I ) max )],(E I ) max Maximum permissible pixel error;

[0036] S2.4: The monitoring results obtained in steps S2.1-S2.3 are fused to obtain the intelligent pointing quality management index P, P=b1×P1+b2×P2+b3×P3, where b1, b2 and b3 represent the corresponding weights, which can be obtained by fitting based on historical data using the entropy weight method, for example b1=0.5, b2=0.3 and b3=0.2;

[0037] In this embodiment, it is important to note that after the system starts up, the intelligent pointing adjustment algorithm module begins to work. It uses a laser rangefinder to acquire distance data between the fixed and mobile ends, and combines this with GPS positioning information to calculate the baseline angle, thus completing the initial pointing calibration. The intelligent pointing management module processes data such as the distance deviation between the fixed and mobile ends and the turntable angle to dynamically calibrate the aiming direction of the laser beam, ensuring that the optical axis of the ground receiving equipment (such as a telescope or laser emitting module) can be accurately aligned with the satellite. Whether it is the baseline calibration during the initial system setup phase or the real-time correction when pointing deviations occur due to atmospheric turbulence, equipment vibration, or other factors during communication, the core is to achieve stable and accurate pointing of the satellite target, providing a reliable directional reference for the acquisition, tracking, and data transmission of satellite-to-ground laser communication. The light spot recognition management is laser light spot recognition management.

[0038] In this embodiment, the fixed end needs to be specifically explained: it refers to a fixed structural unit installed at a ground reference position, which is usually rigidly connected to the foundation or stable platform and has a relatively fixed position. It integrates the transmitter of the laser rangefinder, the reference antenna of the GPS positioning module, and angle measurement reference components (such as a fixed reflector). Its main function is to provide a spatial position reference and measurement reference point, providing a stable coordinate origin for the entire pointing adjustment mechanism. The moving end refers to a movable structural unit equipped with core optical receiving components (such as a telescope or a precision tracking system). It can flexibly adjust the azimuth and elevation angles through a turntable or slide rail. It integrates the receiver of the laser rangefinder, the moving antenna of the GPS positioning module, and an angle sensor. It can provide real-time feedback on its relative position relationship with the fixed end. Through collaborative measurement with the fixed end, it provides dynamic data for baseline angle calculation and pointing accuracy correction.

[0039] Adaptive Link Establishment Management Module: This module processes ground-received link establishment data, calculates the link establishment efficiency management index, link establishment power compensation management index, and link stability management index, and fuses them to obtain the adaptive link establishment quality management index. This index is then transmitted to the remote monitoring and maintenance module, including the following steps:

[0040] S3.1: Link Establishment Efficiency Management: Link establishment efficiency management uses a built-in high-precision timer (such as a hardware timer in an embedded system or a high-precision timing API in the operating system) to record the time t0 from the triggering of the theoretical minimum link establishment process and the actual time t from the start of link establishment to successful link establishment. Then, through the signal power detection circuit of the system's RF front-end module (such as a logarithmic detector or ADC to acquire the RF signal power value and convert it to dBm), the actual receiver signal strength S and the preset minimum signal strength S for successful link establishment are obtained. min and ideal signal strength S max Obtain the blockchain building efficiency management index W1. ;

[0041] S3.2: Link establishment power compensation management, including:

[0042] S3.2.1: Signal Strength Monitoring: Real-time acquisition of the signal strength S at the receiving end, and comparison with the minimum signal strength S at which a link was successfully established. min contrast;

[0043] S3.2.2: Compensation Trigger Judgment: When the actual signal strength is detected to be lower than the preset threshold S th At that time, the power compensation process is initiated;

[0044] S3.2.3: Stepped Power Adjustment: Gradually increase the laser emission power in preset steps (e.g., 2dB), monitoring the signal strength after each adjustment with an interval of Δt (e.g., 50ms). When the current signal strength S is monitored...m Greater than or equal to the preset threshold S th At time or when the maximum transmission power S is reached max When this happens, power adjustment is stopped;

[0045] S3.2.4: Calculate the link establishment power compensation management index W2. ;

[0046] S3.3: Link Stability Management: Record the normal operating time t of the link within the link monitoring period T. z Obtain the link availability coefficient η(t), η(t) = t z If the link availability coefficient η(t) is less than the corresponding threshold, then record the recovery time t after the link interruption. re Then, count the number N interruptions where the recovery time is less than the corresponding threshold. z Obtain the interrupt recovery efficiency coefficient η(t) re ), η(t) re )=N z / TN z TN z The total number of interruptions is used to obtain the link stability management index W3, where W3 = η(t) + η(t) re );

[0047] S3.4: The chain establishment efficiency management index, chain establishment power compensation management index and link stability management index are fused to obtain the adaptive chain establishment quality management index W, W=c1×W1+c2×W2+c3×W3, where c1, c2 and c3 represent the corresponding weights, which can be obtained by fitting based on historical data using the entropy weight method, for example c1=0.4, c2=0.3 and c3=0.2;

[0048] This embodiment specifically explains that adaptive link establishment refers to formulating and executing an efficient strategy for establishing and maintaining satellite-to-ground communication links. Based on satellite orbit data, including satellite position, velocity, orbital period, and orbital inclination, an orbital prediction algorithm (such as a convolutional neural network) is used to calculate in advance the time window in which the satellite will pass over the local receiving station, as well as the azimuth and elevation angles at which it enters and leaves that window. For example, based on the satellite orbit parameters and the latitude and longitude information of the local receiving station, it can accurately predict that the satellite will enter the link-establishable area from the southeast of the local receiving station at a certain time with an elevation angle of 30°. The domain lasts for 10 minutes; the receiving equipment monitors the satellite signal strength in real time, records the current signal strength value and the trend of signal strength change, and combines historical data to analyze the signal strength distribution of the satellite at different locations and times, determine the normal fluctuation range of signal strength and the minimum signal strength threshold required for link establishment. For example, through statistical analysis of the historical monitoring data of a certain satellite, it is found that its normal signal strength range in the link establishment area is -50dBm to -30dBm, and the minimum signal strength for successful link establishment is -60dBm, thereby improving the success rate of link establishment and maintaining link stability.

Based on abnormal monitoring results, it triggers corresponding maintenance mechanisms and transmits the maintenance mechanism information to the ground receiving and feedback module. This includes the following steps:

This includes checking whether the equipment installation accuracy management index Q1 and the interface communication stability management index Q2 meet the corresponding expectations, and transmitting any abnormal results that do not meet the expectations to the ground receiving feedback module. Otherwise, the monitoring is normal.

This includes checking whether the initial pointing accuracy management index P1, the real-time error correction management index P2 and the spot recognition accuracy P3 meet the corresponding expectations, and transmitting the abnormal results that do not meet the expectations to the ground receiving feedback module. Otherwise, it means that the monitoring is normal.

[0052] S4.3: Compare the adaptive chain building quality management index W with the corresponding threshold W th Compare the results; if W < W thIf the adaptive link establishment quality monitoring is abnormal, the device's adaptive link establishment operation and maintenance mechanism will be triggered.
