Description

Technical Field

[0001] The present invention relates to the technical field of communication management, and in particular to a rapidly deployable laser ground receiving system. Background Art

[0002] In the development process of modern satellite communications, the management efficiency requirements of ground receiving systems are becoming increasingly stringent. With the rapid development of satellite technology, the amount of data generated by satellite detection has increased 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 ultra-high-speed transmission of massive data.

[0003] Traditional solutions use fixed ground station construction and mobile vehicle-mounted ground station construction. For fixed ground station construction, candidate areas are screened through satellite remote sensing data, such as drought, low cloud, and low electromagnetic interference areas. On-site geological drilling is conducted to assess the bearing capacity of the foundation. Meteorological stations are deployed for continuous monitoring for more than one year to obtain data such as wind speed and precipitation. Vehicle-mounted ground stations are equipped with a built-in ATP (capture, tracking, targeting) system, transceiver module, and data processing unit to achieve the purpose of deploying laser ground reception.

[0004] However, traditional ground receiving systems have many problems in deployment and management: on the one hand, the construction of fixed ground stations, the quality of equipment installation, and the reliability of cable connections rely on manual experience and cannot be quantitatively evaluated and monitored through data-based means, which poses performance risks; on the other hand, although mobile vehicle-mounted ground stations have a certain degree of flexibility, they lack an integrated data management system to achieve high-precision measurement and intelligent monitoring of key processes such as pointing and link establishment, affecting the rapid aiming, capture and tracking performance of satellite-to-ground communications; the existing system lacks data-based link establishment monitoring and adaptive adjustment capabilities, resulting in poor communication stability and reliability; in terms of pointing adjustment, there is a lack of effective data processing and monitoring methods, and it is difficult to achieve ideal accuracy; therefore, it is very important to develop a ground receiving system that can be quickly deployed, has data-based high-precision management and monitoring capabilities, and efficient intelligent operation and maintenance capabilities. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a rapidly deployable laser ground receiving system to solve the problems raised in the above-mentioned background technology.

The equipment assembly data, equipment pointing data and ground receiving link establishment data are transmitted to the ground receiving equipment assembly management module, intelligent pointing management module and adaptive link establishment management module respectively; Ground receiving equipment assembly management module: used to process the equipment assembly data, calculate the equipment installation accuracy management index and the interface communication stability management index respectively, integrate them to obtain the equipment assembly quality management index, and transmit it to the remote monitoring and operation and maintenance module; Intelligent pointing management module: This module processes device pointing data and performs initial pointing accuracy management, real-time error correction management, and spot recognition management. It then integrates the management results to obtain intelligent pointing quality management indicators, which are then transmitted to the remote monitoring and operation and maintenance module. Adaptive link establishment management module: used to process the link establishment data received on the ground, calculate the link establishment efficiency management index, link establishment power compensation management index and link stability management index respectively, and integrate them to obtain the adaptive link establishment quality management index, and transmit it to the remote monitoring and operation and maintenance module; Remote monitoring and operation and maintenance module: This module uses IoT communication technology to remotely monitor equipment assembly quality management indicators, intelligent pointing quality management indicators, and adaptive link establishment quality management indicators. It triggers corresponding operation and maintenance mechanisms based on abnormal monitoring results, and transmits this information to the ground receiving feedback module. Ground receiving feedback module: transmits the operation and maintenance mechanism information obtained by the remote monitoring and operation and maintenance module to the management terminal for human-computer interaction.

[0007] The technical effects and advantages of the present invention are as follows: 1. The present invention uses ground receiving equipment assembly modules to enable rapid device connection interfaces, significantly shortening assembly time. Furthermore, based on equipment assembly quality management indicators, it ensures device installation accuracy and inter-device communication stability, enabling rapid system deployment and management, meeting rapid response requirements in emergency situations. 2. The present invention uses an intelligent pointing management module, combined with ranging data, GPS positioning information and light spot recognition technology, to correct pointing errors and manage light spot recognition in real time. It can maintain high pointing accuracy management even in complex environments, achieving high-precision pointing and stable tracking management of satellites, laying the foundation for efficient link establishment management and improving the efficiency of intelligent pointing management. 3. The present invention uses an adaptive link establishment management module to evaluate link establishment efficiency based on actual link establishment time and theoretical link establishment time, thereby helping to shorten link establishment time. By monitoring real-time signal strength to compensate for link establishment power and dynamically adjust communication signal strength, the present invention significantly improves the link establishment success rate. At the same time, it can maintain the stability of the communication link in complex environments and reduce the duration of communication interruptions. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The ground receiving equipment assembly management module is used to process the equipment assembly data, calculate the equipment installation accuracy management index and the interface communication stability management index respectively, integrate them to obtain the equipment assembly quality management index, and transmit it to the remote monitoring and operation and maintenance module, including the following steps: S1.1: First, use a laser rangefinder to measure the deviation between the three-dimensional coordinates (x, y, z) of the actual installation position of the equipment on site and the design installation coordinates (x0, y0, z0). All coordinate units are consistent, and the deviation coefficient η(zb) is obtained. , Δx max , Δy maxand Δz max represents the maximum deviation thresholds in the x, y, and z directions, n is the number of devices, and i is the i-th device. The device installation accuracy management index Q1 is obtained, Q1=1 / [1+η(zb)]. Then, using network analysis equipment (such as a network analyzer, communication delay test tools, etc.), the data transmission bandwidth bw, end-to-end device communication delay dL, and packet loss rate db during data transmission between devices through the preset API interface are monitored to obtain the interface communication stability management index Q2. , bw0, dL0 and db0 are the designed bandwidth, the maximum allowed communication delay and the maximum allowed packet loss rate respectively; S1.2: Integrate the equipment installation precision management index and the interface communication stability management index to obtain the equipment assembly quality management index Q, where Q = a1 × Q1 + a2 × Q2, where a1 and a2 represent corresponding weights, which can be obtained by fitting the entropy weight method based on historical data, for example, a1 = 0.7 and a2 = 0.3. Intelligent pointing management module: This module processes device pointing data and performs initial pointing accuracy management, real-time error correction management, and spot recognition management. It then integrates the management results to obtain intelligent pointing quality management indicators and transmits them to the remote monitoring and operation and maintenance module. The module includes the following steps: S2.1: Initial pointing accuracy management: The azimuth angle Az and pitch angle El of the equipment in the ground receiving equipment module (such as gyroscope angle, accelerometer position) are obtained through the attitude sensor, and compared with the design azimuth angle Az des and pitch angle El des By comparison, we can get the pointing error Δθ, , in radians or degrees; at the same time, the deviation |Δd| between the measured distance and the actual distance between the fixed end and the mobile end is obtained by the laser rangefinder. If Δθ ≤ the corresponding threshold Δθ th (e.g. 0.1 rad) and |Δd|≤Δd max , Δd max If the error is the maximum allowed, the calibration is successful. Otherwise, an alarm is triggered and recalibration is performed. The number of successful tests N and the total number of tests TN are recorded to obtain the initial pointing accuracy management index P1. ; S2.2: Real-time error correction management: Adjust the pointing mechanism based on the pointing error alarm signal and output the correction 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≤ corresponding threshold Δθ re th The number of times N va , get the real-time error correction management index P2, P2=N va / TN; S2.3: Light spot recognition management: Use the CCD camera to collect n2 sets of light spot images under n1 different conditions (such as different lighting, different satellite signal strength, etc.), and extract the pixel coordinates (u I ,v I ), and compared with the real spot center pixel coordinates (u0, v0), to obtain the spot center pixel error E of each image I , , the pixel error E of the center of the n1×n2 image spot I The average pixel error μ(E I ), we get the spot recognition accuracy P3, P3=exp[-(μ(E I ) / (E I ) max )],(E I ) max is the maximum allowed pixel error; S2.4: Fusion the monitoring results from steps S2.1-S2.3 to obtain the intelligent pointing quality management indicator P, where P = b1 × P1 + b2 × P2 + b3 × P3, where b1, b2, and b3 represent corresponding weights, which can be obtained by fitting historical data using the entropy weight method, for example, b1 = 0.5, b2 = 0.3, and b3 = 0.2. What needs to be specifically explained in this embodiment is that after the system is started, the system's intelligent pointing adjustment algorithm module starts working, using a laser rangefinder to obtain distance data between the fixed end and the mobile end, combining it with GPS positioning information, and calculating the baseline angle to complete the initial pointing calibration; the intelligent pointing management module dynamically calibrates the aiming direction of the laser beam by processing data such as the distance deviation between the fixed end and the mobile end and the turntable angle, ensuring that the optical axis of the ground receiving equipment (such as the telescope and the laser transmitting module) can be accurately aligned with the satellite; whether it is baseline calibration in the initial system formation stage or real-time correction when pointing offsets are caused by factors such as atmospheric turbulence and equipment vibration during communication, the core is to achieve stable and precise pointing of the satellite target, providing a reliable direction reference for the capture, tracking and data transmission of satellite-to-ground laser communications; the light spot recognition management is laser light spot recognition management.

[0018] What needs to be specifically explained in this embodiment is that the fixed end refers to a fixed structural unit installed at a ground reference position, which is usually rigidly connected to the foundation or a stable platform, has a relatively fixed position, and integrates the transmitting end of the laser rangefinder, the reference antenna of the GPS positioning module, and the angle measurement reference component (such as a fixed reflector). Its main function is to provide a spatial position reference and measurement reference point, and provide a stable coordinate origin for the entire pointing adjustment mechanism; the mobile end refers to a movable structural unit equipped with core optical receiving components (such as a telescope, a precision tracking system), which can achieve flexible adjustment of the azimuth and pitch angles through a turntable or a slide rail, integrates the receiving end of the laser rangefinder, the mobile antenna of the GPS positioning module, and the angle sensor, and can provide real-time feedback on the relative position relationship between itself and the fixed end. Through collaborative measurement with the fixed end, it provides dynamic data for baseline angle calculation and pointing accuracy correction.

[0019] Adaptive link establishment management module: It is used to process the link establishment data received on the ground, calculate the link establishment efficiency management index, link establishment power compensation management index, and link stability management index, and integrate them to obtain the adaptive link establishment quality management index, which is then transmitted to the remote monitoring and operation and maintenance module. It includes the following steps: S3.1: Link establishment efficiency management: Link establishment efficiency management uses the system's built-in high-precision timer (such as the embedded system's hardware timer, the operating system's high-precision timing API) to record the theoretical minimum link establishment process trigger to completion time t0 and the actual link establishment time from link start to successful link establishment t. Then, through the system's RF front-end module's signal power detection circuit (such as the logarithmic detector, ADC to collect RF signal power values ​​and convert them into dBm units), the actual receiving end 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 chain building efficiency management index W1, ; S3.2: Link establishment power compensation management, including: S3.2.1: Signal strength monitoring: Real-time acquisition of the signal strength S of the receiving end and comparison with the minimum signal strength S for successful link establishment min contrast; S3.2.2: Compensation trigger judgment: When the actual signal strength is detected to be lower than the preset threshold S th When , the power compensation process is started; S3.2.3: Step-by-step power adjustment: gradually increase the laser emission power according to the preset step size (such as 2dB).

For example, c1 = 0.4, c2 = 0.3, and c3 = 0.2. What needs to be specifically explained in this embodiment is that adaptive link establishment refers to the formulation and implementation of an efficient satellite-to-ground communication link establishment and maintenance strategy. Based on satellite orbit data, including information such as the satellite's position, speed, operating cycle, orbital inclination, etc., an orbit 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 in the future, and the azimuth and pitch angles of entering and leaving the window. For example, based on the satellite orbit parameters and the latitude and longitude information of the local receiving station, it is accurately predicted that the satellite will enter the link-establishable area from the southeast of the local receiving station at a pitch angle of 30° at a certain moment. domain, lasting 10 minutes; use the receiving device to monitor the satellite signal strength in real time, record the current signal strength value and the signal strength change trend, and combine historical data to analyze the satellite's signal strength distribution 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 historical monitoring data of a certain satellite, it is concluded 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, which improves the link establishment success rate and maintains link stability.
