Wired is a telephone line or a dedicated cable; wireless is the use of radio, microwave and satellite technology. Information cannot be changed during the transmission process, and the information itself cannot be transmitted or received. There must be a carrier, such as data, language, signal, etc., and the transmission and reception have a common interpretation of the carrier;

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1:

[0036] See also Figure 1 As shown, the present invention is a transmission pipeline safety supervision method based on multi-source data analysis, comprising the following steps:

[0037] Step 1: Collect the matching information and flow direction evaluation values ​​of each information source of the target transmission pipeline, and substitute them into step 2 for information source security supervision assessment and analysis;

[0038] Step 2: Based on the information source security supervision assessment analysis under information feedback, the obtained information risk index is subjected to discriminant analysis. If a feedback instruction is obtained, it is substituted into step 3. If an alarm instruction is obtained, feedback is output;

[0039] Step 3: Pipeline supervision management analysis based on feedback instructions. If a safety instruction is obtained, step 4 and step 5 are substituted. If a supervision warning instruction is obtained, feedback is output;

[0040] Step 4: Based on the information progressive method, the pipeline transmission risk defect assessment analysis is performed from the appearance and performance of the target transmission pipeline, and the obtained pipeline defect coefficient is compared and analyzed. If a qualified instruction is obtained, it is substituted into step 6. If an unqualified instruction is obtained, feedback is output;

[0041] Step 5: Conduct pipeline transmission stability supervision assessment and analysis from the transmission characteristic angle of the target transmission pipeline, and compare and analyze the obtained line flow risk value. If a normal instruction is obtained, substitute it into step 6. If an abnormal instruction is obtained, output feedback;

[0042] Step 6: Based on the evaluation and analysis of the actual transmission performance characteristics of the target transmission pipeline under normal instructions and qualified instructions, the actual circulation risk coefficient obtained is discriminated and processed, and the obtained dynamic stability instruction or dynamic alarm instruction is output and fed back;

[0043] In the embodiment of the present invention, the information source security supervision evaluation analysis is initially performed from the perspective of the security of each information source of the target transmission pipeline to determine whether each information source of the target transmission pipeline is safe, so as to timely adjust the target transmission pipeline supervision plan to improve the transmission security of the target transmission pipeline and improve the supervision performance of each information source. The specific information source security supervision evaluation analysis process is as follows:

[0044] Set the monitoring period, obtain the matching information of each information source of the target transmission pipeline within the monitoring period, including IP address, name, etc., and compare and analyze the matching information with the authorized information database, obtain the number of matching information that does not belong to the authorized information database, and set the number of matching information that does not belong to the authorized information database as the information risk index, and perform discriminant analysis on the information risk index:

[0045] If the information risk index is equal to zero, a feedback instruction is generated;

[0046] If the information risk index is not equal to zero, an alarm instruction is generated. When the alarm instruction is generated, the preset warning operation corresponding to the alarm instruction is immediately performed, so as to timely interrupt the risky information source to improve the transmission security of the target transmission pipeline;

[0047] In the embodiment of the present invention, the authorization information base represents an authentication database constructed by an authenticated registered user of the target transmission pipeline;

[0048] When a feedback instruction is generated, based on the pipeline supervision management analysis under the feedback instruction, the pipeline supervision management analysis process is as follows:

[0049] The flow direction evaluation value of the target transmission pipeline information source is obtained. The flow direction evaluation value indicates the total number of times the information flow supervision of the information source is lost, and the flow direction evaluation value is judged:

[0050] If the flow direction evaluation value is less than or equal to the preset flow direction evaluation value threshold, a safety instruction is generated;

[0051] If the flow direction evaluation value is greater than the preset flow direction evaluation value threshold, a supervision warning instruction is generated. When a safety instruction or a supervision warning instruction is generated, the preset warning operation corresponding to the safety instruction or the supervision warning instruction is immediately performed, so as to timely adjust the supervision plan of the target transmission pipeline to improve the transmission safety of the target transmission pipeline and improve the supervision performance of each information source;

[0052] When generating safety instructions: Based on the information progressive method, the pipeline transmission risk defect assessment and analysis is carried out from the appearance and performance of the target transmission pipeline to determine whether the transmission risk of the target transmission pipeline itself is too high, so as to conduct reasonable and targeted management of the target transmission pipeline according to the information feedback to reduce the transmission risk of the target transmission pipeline. The specific pipeline transmission risk defect assessment and analysis process is as follows:

[0053] Divide the target transmission pipeline into g sub-length segments, where g is a natural number greater than zero, and obtain the status information of each sub-length segment within the monitoring period, the status information including the appearance status coefficient and the performance status coefficient;

[0054] In the embodiment of the present invention, the appearance state coefficient represents the difference between the appearance feature image of the target transmission pipeline in the sub-length segment and the standard appearance feature image. It should be noted that the larger the value corresponding to the appearance state coefficient is, the greater the abnormal risk of the transmission pipeline is;

[0055] In the embodiment of the present invention, the performance status coefficient indicates the frequency corresponding to the actual transmission loss of the target transmission pipeline in the sub-length section exceeding the preset transmission loss. It should be noted that the performance status coefficient is an influencing parameter reflecting the transmission status of the transmission pipeline;

[0056] Obtain the number of appearance state coefficients and performance state coefficients that are greater than or equal to a preset appearance state coefficient threshold and a preset performance state coefficient threshold, and set them as the carrier obstruction index, and set the ratio between the sub-length segment corresponding to the carrier obstruction index = 1 or the carrier obstruction index = 2 and the total number of sub-length segments as the pipeline defect coefficient;

[0057] And compare and analyze the pipeline defect coefficient with the preset pipeline defect coefficient threshold:

[0058] If the ratio between the pipeline defect coefficient and the preset pipeline defect coefficient threshold is less than 1, a qualified instruction is generated;

[0059] If the ratio between the pipeline defect coefficient and the preset pipeline defect coefficient threshold is greater than or equal to 1, an unqualified instruction is generated. When a qualified instruction or an unqualified instruction is generated, the preset early warning operation corresponding to the qualified instruction or the unqualified instruction is immediately performed, so as to reasonably and targetedly manage the target transmission pipeline according to the information feedback, so as to reduce the transmission risk of the target transmission pipeline.

[0060] Embodiment 2:

[0061] When generating a safety instruction: perform pipeline transmission stability supervision and evaluation analysis from the transmission characteristics of the target transmission pipeline to further analyze whether the transmission of the target transmission pipeline is safe, so as to manage the target transmission pipeline in a timely manner to improve the transmission safety and smoothness of the target transmission pipeline. The specific pipeline transmission stability supervision and evaluation analysis process is as follows:

[0062] The monitoring period is divided into i sub-time periods, where i is a natural number greater than zero. The number of transmission risk information corresponding to the target transmission pipeline in each sub-time period is obtained. The transmission risk information includes loss, jamming, etc. The number of transmission risk information corresponding to the target transmission pipeline in each sub-time period is set as the transmission obstruction index, and the transmission obstruction index is judged:

[0063] If the transmission obstruction index = 0, a stable signal is generated;

[0064] If the transmission barrier index = 1 or the transmission barrier index = 2, a risk signal is generated;

[0065] The number of risk signals generated during the monitoring period and the number of stable signals are obtained, and the ratio between the number of risk signals generated and the number of stable signals is set as the line flow risk value, and the line flow risk value is compared with the preset line flow risk value threshold for analysis:

[0066] If the ratio between the line circulation risk value and the preset line circulation risk value threshold is less than 1, a normal instruction is generated;

[0067] If the ratio between the line circulation risk value and the preset line circulation risk value threshold is greater than or equal to 1, an abnormal instruction is generated. When a normal instruction or an abnormal instruction is generated, a preset warning operation corresponding to the normal instruction or the abnormal instruction is immediately performed, so as to timely manage the target transmission pipeline to improve the transmission safety and stability of the target transmission pipeline;

[0068] When normal instructions and qualified instructions are generated: based on the evaluation and analysis of the actual transmission performance characteristics of the target transmission pipeline under normal instructions and qualified instructions, the security risk is judged from the perspective of the actual transmission performance of the target transmission pipeline, so as to timely rationalize the transmission performance of the target transmission pipeline and improve the transmission efficiency and reliability of the target transmission pipeline. The specific actual transmission performance characteristics evaluation and analysis process is as follows:

[0069] The monitoring period is divided into o sub-time nodes, where o is a natural number greater than zero, and the transmission performance information of the target transmission pipeline in each sub-time period is obtained. The transmission performance information represents the actual transmission rate and throughput. A rectangular coordinate system is established with the sub-time node as the X-axis and the actual transmission rate and throughput as the Y-axis respectively. The actual transmission rate curve and the throughput curve are obtained by plotting points, and the difference between the maximum and minimum values ​​in the actual transmission rate curve and the difference between the maximum and minimum values ​​in the throughput curve are obtained, and they are set as the rate floating span and the throughput floating span respectively. It should be noted that the rate floating span and the throughput floating span are two parameters that reflect the transmission safety of the target transmission pipeline;

[0070] At the same time, the environmental interference information of the environment in which the target transmission pipeline is located in each sub-length within the monitoring period is obtained, and the environmental interference information includes temperature, electromagnetic interference value, etc. The corresponding value of the environmental interference information deviates from the threshold corresponding to the preset range, and is set as the flow obstruction value, and the ratio between the number of sub-length segments corresponding to the flow obstruction value greater than the preset flow obstruction value threshold and the total number of sub-lengths is set as the information flow level. It should be noted that the larger the value of the information flow level, the greater the impact of the environment on the information transmission of the target transmission pipeline;

[0071] The number of rate floating spans, throughput floating spans and information circulation levels that are greater than or equal to the preset rate floating span threshold, the preset throughput floating span threshold and the preset information circulation level threshold is set as the actual circulation risk coefficient, and the actual circulation risk coefficient is judged:

[0072] If the actual circulation risk coefficient = 0, a dynamic stabilization instruction is generated;

[0073] If the actual circulation risk coefficient is ≠0, a dynamic alarm instruction is generated. When a dynamic stabilization instruction or a dynamic alarm instruction is generated, a preset warning operation corresponding to the dynamic stabilization instruction or the dynamic alarm instruction is immediately performed, so as to timely and rationally manage the transmission performance of the target transmission pipeline, so as to improve the transmission efficiency and reliability of the target transmission pipeline;

[0074] In summary, the present invention preliminarily conducts information source security supervision assessment and analysis from the perspective of the security of each information source of the target transmission pipeline to determine whether each information source of the target transmission pipeline is safe, so as to timely adjust the target transmission pipeline supervision plan to improve the transmission security of the target transmission pipeline, and at the same time improve the supervision performance of each information source, and based on the information progressive method, the pipeline transmission risk defect assessment and analysis is performed from the two points of the appearance and own performance of the target transmission pipeline to determine whether the transmission risk of the target transmission pipeline itself is too high, so as to perform reasonable and targeted management of the target transmission pipeline according to the information feedback situation. In order to reduce the transmission risk of the target transmission pipeline, at the same time, the pipeline transmission stability supervision evaluation analysis is carried out from the perspective of the transmission characteristics of the target transmission pipeline, so as to further analyze whether the transmission of the target transmission pipeline is safe, so as to timely manage the target transmission pipeline, so as to improve the transmission safety and smoothness of the target transmission pipeline, and based on the target transmission pipeline's own transmission and the actual transmission performance characteristics under normal transmission characteristics, the evaluation and analysis is carried out, so as to judge the safety risk from the perspective of the actual transmission performance of the target transmission pipeline, so as to timely and rationally manage the transmission performance of the target transmission pipeline, so as to improve the transmission efficiency and reliability of the target transmission pipeline.

[0075] The threshold is set to facilitate comparison. The threshold depends on the amount of sample data and the number of bases set by technicians in this field for each set of sample data, as long as it does not affect the proportional relationship between the parameter and the quantized value.

[0076] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
