Description

Technical Field

[0001] The present invention relates to the technical field of optical cable transmission, and in particular to an optical cable transmission system based on multi-dimensional data monitoring. Background Art

[0002] Optical fiber transmits data using optical signals. Compared to traditional cables, optical cables offer higher bandwidth, longer transmission distances, and lower signal attenuation. With the rapid development of digital signal processing and digital chips, smart array antennas based on digital multi-beamforming technology are widely used in fields such as next-generation radar, wireless mobile communications, satellite communications, and satellite navigation. These applications require real-time, high-speed transmission of multi-beam data and control signals between antennas and hosts, requiring bandwidths as high as Gb / s. On large carriers (such as ships, spacecraft, and large mobile land vehicles), the distance between antennas and hosts can be several meters or even hundreds of meters. Currently, the mainstream solution for data transmission between antennas and hosts is optical fiber transmission. However, optical modules are bulky and require a demanding engineering environment. Furthermore, if bidirectional communication between hosts and antennas is required, the more expensive multimode optical fiber is required. Therefore, a new multi-beam data transmission solution is needed.

A trusted WLAN wireless module and an encryption module are provided inside the optical cable junction box. The optical cable junction box is used to receive optical cable monitoring information from the optical cable monitoring terminal after passing a first security authentication and a second security authentication in sequence, and forward the received optical cable monitoring information from the optical cable monitoring terminal to the background server; wherein the first security authentication is a hardware security startup authentication of the optical cable junction box based on the internal encryption module, and the second security authentication is a three-way peer-to-peer bidirectional authentication performed between the optical cable junction box, the optical cable monitoring terminal, and the background server; it can be seen that the existing optical cable monitoring and transmission system lacks a method for identifying the type of optical signal input at the receiving end and performing corresponding processing according to different types, resulting in low efficiency and low reliability of optical cable transmission.

[0072] The environmental parameter monitoring unit is used to monitor environmental parameters in real time, and the environmental parameters include real-time environmental temperature and real-time environmental pressure;

[0073] The signal analysis unit is used to analyze the cause of signal attenuation based on environmental parameters and signal characteristics when determining optical signal loss, and to obtain current monitoring results, and calculate the real-time bit error rate based on the current monitoring results.

[0074] Specifically, the optical signal attenuation value monitoring unit includes a first calculation subunit, a second calculation subunit, an optical signal attenuation value subunit and a light intensity attenuation comparison subunit, wherein:

[0075] The first calculation subunit is used to calculate the real-time light intensity attenuation value based on the input light intensity and the output light intensity;

[0076] The second calculation subunit is used to calculate the real-time light intensity attenuation degree based on the standard light intensity attenuation value and the real-time light intensity attenuation value;

[0077] Among them, the real-time light intensity attenuation degree is the difference between the standard light intensity attenuation value and the real-time light intensity attenuation value;

[0078] The optical signal attenuation value subunit is used to determine the real-time light intensity attenuation degree according to the standard light intensity attenuation degree:

[0079] If the real-time light intensity attenuation is less than or equal to the standard light intensity attenuation, it is determined that the optical signal transmission state is normal;

[0080] The light intensity attenuation comparison subunit is used to compare the standard light intensity attenuation value with the real-time light intensity attenuation value when the real-time light intensity attenuation degree is greater than the standard light intensity attenuation degree:

[0081] If the real-time light intensity attenuation value is less than or equal to the standard light intensity attenuation value, it is determined that the optical signal transmission status is normal;

[0082] If the real-time light intensity attenuation value is greater than the standard light intensity attenuation value, it is determined that the optical signal transmission state is abnormal.

[0083] The standard optical attenuation level indicates the range of optical intensity attenuation per unit length during light transmission, measured in dB / km. This value can be determined based on the type and quality of the optical cable, as well as the requirements of the operating environment. Generally, the standard optical attenuation level for single-mode optical cables is typically between 0.2dB / km and 0.5dB / km, while the standard optical attenuation level for multimode optical cables is typically between 2dB / km and 4dB / km.

[0084] Monitor the attenuation of optical signals in real time to analyze the transmission status of optical signals.

[0085] Specifically, the first calculation subunit calculates the real-time light intensity attenuation value based on the input light intensity and the output light intensity, Qs=10×a×lg(Asi / Aso);

[0086] Among them, Qs is the real-time light intensity attenuation value; Asi is the input light intensity; Aso is the output light intensity; and a is the set light intensity attenuation coefficient.

[0087] By setting the light intensity attenuation coefficient, the optical cable transmission can be adapted to different scenarios, meet different monitoring operation requirements, improve monitoring effects, and realize the application of the system in infrastructure and management in various fields, thus improving the applicability and practicality of the system.

[0088] Specifically, the transmission duration monitoring unit includes a comparison subunit and a determination subunit, wherein:

[0089] The comparison subunit is used to compare the standard signal transmission time with the actual signal transmission time;

[0090] The determination subunit determines that the optical signal is lost when the actual signal transmission time is longer than the standard signal transmission time.

[0091] The signal transmission time indicates the time required for an optical signal to be transmitted in an optical fiber. It is related to the transmission distance, the material structure of the optical fiber, and the equipment model. It is generally 2 / 3 of the speed of light, approximately 200,000 kilometers per second, and is measured in nanoseconds. The standard signal transmission time indicates the change in signal transmission time caused by a slight deformation of the pipeline. If the actual signal transmission time is determined to be greater than the standard signal transmission time, it means that the optical signal has not been received for a long time and is lost.

[0092] Specifically, the signal analysis unit includes a temperature analysis subunit, a pressure analysis subunit and a signal feature analysis subunit, wherein:

[0093] The temperature analysis subunit is used to compare the allowed temperature difference with the actual temperature difference;

[0094] If the actual temperature difference is less than or equal to the allowable temperature difference, the current monitoring result is determined to be an erroneous monitoring result;

[0095] The pressure analysis subunit is used to compare the pressure threshold with the actual pressure when the actual temperature difference is greater than the allowable temperature difference;

[0096] The signal feature analysis subunit is used to obtain the actual signal shape similarity when the actual pressure is less than the pressure threshold, compare the standard signal shape similarity with the actual signal shape similarity, and determine the attenuation cause based on the comparison result;

[0097] Among them, when the actual signal shape similarity is less than the standard signal shape similarity, it is determined that the optical signal energy is leaking; when the actual signal shape similarity is greater than or equal to the standard signal shape similarity, the current monitoring result is determined to be false monitoring; when the actual pressure is greater than or equal to the pressure threshold, it is determined that a bend occurs.

[0098] The pressure threshold indicates the set threshold for abnormal pressure changes, which is related to the requirements of specific scenarios and the characteristics of the optical cable; the allowable temperature difference indicates the set value that defines a sudden temperature change. If the actual temperature difference, that is, the difference between the temperature value monitored in the current cycle and the temperature value monitored in the previous cycle, exceeds the allowable temperature difference, it indicates that a sudden temperature change has occurred.

[0099] When optical signals are lost or transmission performance is poor, quickly identify the problem and take appropriate measures to reduce potential signal loss.

[0100] Specifically, the signal analysis unit further includes a bit error rate monitoring unit,

[0101] The bit error rate monitoring unit is used to record the total number of bits sent and the number of error bits received within a preset monitoring period, and calculate the actual bit error rate based on the total number of bits and the number of error bits;

[0102] The number of false monitoring results in the current monitoring period is obtained to obtain the number of error bits, and the percentage of the error bits to the total number of bits is calculated to obtain the actual bit error rate; the total number of bits is the total number of bits sent in the preset monitoring period;

[0103] In this embodiment, the number of error bits is the number of received error bits, that is, the monitoring result is the number of false monitorings.

[0104] By comparing the actual bit error rate with the standard bit error rate, the system can dynamically adjust the data bit width and clock frequency, optimize the signal transmission quality, and ensure the integrity and accuracy of the data.

[0105] Specifically, the signal processing module includes a synchronization unit, a framing unit and a speed change unit, wherein:

[0106] The synchronization unit is used to synchronize the electrical signal of the second signal type with a local clock to obtain an initial data frame;

[0107] The framing unit is used to reassemble, check and count the initial data frames to obtain the target data frames;

[0108] The speed changing unit is used to adjust the data bit width and clock parameters based on the actual bit error rate, and the clock parameter is the clock frequency.

[0109] Specifically, the framing unit includes a reassembly subunit, a check subunit and a frame counting subunit, wherein:

[0110] The recombining subunit is used to integrate the initial data frames into complete data frames to obtain intermediate data frames;

[0111] The check subunit is used to perform integrity check on the intermediate data frame to obtain the target data frame;

[0112] The frame counting subunit is used to mark each target data frame with an identifier.

[0113] The synchronization unit ensures that all beam data are aligned in time, and the reassembly subunit integrates the synchronized data into a complete data frame. The verification subunit verifies the integrity of the data frame to ensure that there are no errors in the data transmission process. The frame counting subunit assigns a unique identifier to each data frame for subsequent processing and tracking. Once the data frame is formed and verified, the system will convert these electrical signals into optical signals.

[0114] Specifically, the speed change unit includes a bit error rate comparison subunit, a bit width adjustment subunit and a clock parameter adjustment subunit, wherein:

[0115] The bit error rate comparison subunit is used to compare the standard bit error rate with the actual bit error rate;

[0116] The bit width adjustment subunit is used to reduce the data bit width to a first data bit width when the actual bit error rate is greater than the standard bit error rate, and to increase the data bit width to a second data bit width when the actual bit error rate is less than or equal to the standard bit error rate;

[0117] The clock parameter adjustment subunit is configured to reduce the clock frequency to a first clock frequency when the actual bit error rate is greater than the standard bit error rate, and increase the clock frequency to a second clock frequency when the actual bit error rate is less than or equal to the standard bit error rate;

[0118] Among them, the first data bit width is the product of the current data bit width and the first adjustment step; the second data bit width is the product of the current data bit width and the second adjustment step; the first clock frequency is the product of the current clock frequency and the first adjustment step; the second clock frequency is the product of the current clock frequency and the second adjustment step; the first adjustment step is the difference between 1 and the first adjustment degree; the second adjustment step is the sum of 1 and the second adjustment degree; the first adjustment degree is the ratio of the part of the actual bit error rate that exceeds the standard bit error rate to the actual bit error rate; the second adjustment degree is the ratio of the part of the standard bit error rate that exceeds the actual bit error rate to the standard bit error rate.

[0119] In this embodiment, the standard bit error rate is used to evaluate the signal quality and to determine whether the system performance meets expectations. The set value is related to the fiber characteristics and transmission distance. The standard bit error rate is set to 10 -9 , which means that under ideal conditions, at most one bit error is allowed in every billion bits. If the actual bit error rate is 10 -6 , it means that the system's performance is below standard and may require troubleshooting and optimization.

[0120] When it is determined that the actual bit error rate is greater than the standard bit error rate, it means that the monitored transmission effect is poor, and the data bit width needs to be reduced to reduce the size of each data frame, thereby improving the reliability of transmission, and the clock frequency needs to be reduced to ensure stable data transmission. When it is determined that the actual bit error rate is less than or equal to the standard bit error rate, it means that the transmitted signal quality is good, and consideration should be given to increasing the data bit width to improve data transmission efficiency, and increasing the clock frequency to meet higher data transmission requirements.
