Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of communication transceiver, and in particular to a high-performance satellite communication signal transceiver. Background Art
[0002] With the acceleration of urbanization and the increase in traffic volume, traffic management has become more complex and difficult. Real-time and accurate traffic monitoring can help improve traffic efficiency, reduce congestion and accident rates. Traditional traffic monitoring technologies, such as ground cameras and sensors, have insufficient coverage in some areas, and the real-time and accuracy of data collection are limited. Therefore, new technologies are needed to provide wider coverage and higher reliability. Satellites can cover a wide geographical area and provide more stable communication guarantees. Data transmission via satellite can achieve real-time monitoring and feedback, and event prediction. Therefore, its application in the field of traffic monitoring shows great potential and advantages.
[0003] However, the existing satellite communication signal transceiver equipment, during the long-link multi-node communication process, has interference from various types and intensities of interference sources. As a result, during the communication process of this link and during the traffic monitoring process, the data error of any transmission node can easily lead to deviations in the final prediction results, making it impossible to effectively predict possible events in the future, resulting in the system's slow response in emergencies. There is a lack of reasonable error data compensation behavior, which is not conducive to improving the accuracy of event prediction, and there is a lack of verification mechanism for predicted events and correction mechanism for identified data. Summary of the invention
[0004] 1. Technical issues to be resolved
[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a high-performance satellite communication signal transceiver device, which can effectively solve the problems of the prior art.
[0006] (II) Technical solution
[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] The management module is used to control each functional module and register sub-nodes with upload and receiving permissions;
[0010] A data receiving module is used to receive signal data sent from multiple sub-nodes via satellite, and pre-process the received signal data to obtain parsed data;

The thresholds are updated through real-time data, and the received signal strength values are monitored to locate the interference source. If it exceeds or is lower than the preset threshold, it is marked as a potential interference source. According to the results of the identification algorithm, different interference sources are classified, and the interference intensity is calculated by comparing the difference between the signal strength and the preset threshold, and a certain interference source is quantified into one or more indicators.
[0019] Furthermore, in the process of locating the interference source, the interference source signal is converted to the frequency domain by fast Fourier transform, the spectrum characteristics of the interference source signal are analyzed, and the abnormal signal in a specific frequency range is identified. The discrete Fourier transform calculation formula of the interference source signal is:

[0022] Furthermore, during the analysis of the frequency spectrum characteristics of the interference source signal, the intensity calculation formula for each frequency component is obtained as follows:
[0023]
[0024] In the formula, |X(K)| represents the intensity of the frequency K component, Re(X(K)) represents the real part of X(K), and Im(X(K)) represents the imaginary part of X(K). When the intensity of the frequency K component exceeds the preset threshold, it is marked as an interference signal.
[0025] Furthermore, the calculation formula of the phase O(K) of the frequency K component is:
[0026]
[0027] Furthermore, the attributes of the interference set of the interference identification module include: the identified interference type and its intensity, occurrence time and affected nodes.
[0028] Furthermore, the data compensation module extracts features from the non-lost data during the data reconstruction process to obtain features of the loss value. Based on the features of the non-lost data part and the features of the loss value, a reconstruction model is established and trained through interpolation. For each damaged data point, the reconstruction model obtains the predicted reconstruction value, and fills the predicted reconstruction value back into the original data to form a complete data set.
[0029] Furthermore, the construction and operation process of the comprehensive prediction model in the event prediction module is as follows:

[0033] (III) Beneficial effects
[0034] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects:
[0035] 1. Through proactive measures to identify interference to satellite communications, the interference source can be detected and located in real time, and the type and strength of the interference source can be analyzed, thereby improving the reliability of satellite communication signal reception and the integrity of the data. By analyzing the signal quality and interference type, it helps to reduce errors in communications. After obtaining actual data, the threshold and algorithm recognition planned for the type and strength of the interference source can be adaptively adjusted to ensure that the recognition capability can adapt to changes in various interference environments. In the process of long-link communication, it avoids excessive errors in the overall data due to local node failures or interference.

[0060] Example 2
[0061] At other levels, this embodiment also provides a measure for locating interference sources, which can actively calculate the location and strength of the interference source. In the process of locating the interference source, the interference source signal is converted to the frequency domain through fast Fourier transform, the spectrum characteristics of the interference source signal are analyzed, and abnormal signals in a specific frequency range are identified. The discrete Fourier transform calculation formula of the interference source signal is:
[0062]
[0063] Wherein, X(K) represents the Kth frequency component, K=0, 1, 2, ..., N-1; y(n) represents the discrete sample value of the input signal, n represents the time index, N represents the total number of samples of the input signal, j represents the imaginary unit, and e represents the base of the natural logarithm. In the analysis of the intensity of the frequency K component, by setting a preset threshold, the sensitivity of interference source identification can be flexibly adjusted according to the needs of the actual application environment, thereby improving the applicability and reliability of the system.

[0067] The calculation formula for the phase O(K) of the frequency K component is:
[0068]
[0069] Compared with the existing technology, frequency domain analysis can accurately identify and extract specific frequency ranges and their characteristics in the signal. Compared with time domain signals, frequency domain information is easier to reveal the characteristics and changes of signals, especially in the task of locating interference sources. It can clearly distinguish interference signals from normal signals. By analyzing the real and imaginary parts of the frequency components, the strength of each frequency component can be comprehensively evaluated, thereby ensuring high-sensitivity identification of interference signals and making the location of interference sources more accurate. Not only the intensity is analyzed, but also the phase of the frequency is calculated, which provides an important basis for the identification and subsequent processing of phase interference and enhances the ability to analyze complex signals.
[0070] By combining the strength, phase and spectrum characteristics, a more complex interference source location model can be constructed to improve the monitoring and location capabilities of multi-source interference and meet the needs of complex modern communication environments.
[0071] Working principle: edit and issue control instructions through management module 1, register sub-nodes that meet access requirements, obtain communication data of sub-nodes through data receiving module 2, identify interference information of communication data through interference identification module 3, analyze specific interference source types and location information through interference analysis module 4, compensate damaged sub-node data through data compensation module 5, predict traffic events through event prediction module 6 with compensated data, issue predicted data to designated sub-nodes through data forwarding module 7, verify error between predicted data and real data through verification module 8, if error data exists, adjust identification settings of interference identification module 3 through parameter adjustment module 9 based on error data, update module 91 reports updated data in real time, and performs data feedback periodically;
[0072] The present invention improves the satellite communication signal receiving and processing capabilities, reduces the impact of interference, identifies and locates interference sources in real time, quickly takes countermeasures, accurately predicts future interference, takes preventive measures in advance, optimizes interference identification and processing strategies, and improves the reliability and stability of signal transmission.
