Description

Technical Field

[0001] This document relates to the field of pipeline safety, and more particularly to an intrinsic safety system for natural disasters in underground pipelines. Background Art

[0002] In recent years, natural disasters have occurred frequently, causing pipeline accidents such as underground pipeline breakage, deformation, blockage, damage to anti-corrosion layers, and damage to ancillary facilities that lead to pipeline failure, posing huge risks to urban safety. Pipeline disaster prevention factors have evolved from normal safety protection to sudden and extreme unknown threat risk protection.

[0003] At the same time, the frequent occurrence of natural disasters has also upgraded disaster protection from seasonal to sudden, and the disaster recovery safety of underground pipelines and their functional safety and information security overlap, causing problems that have never been exposed in underground pipeline safety management to begin to appear. Urban underground pipeline management methods have generally been upgraded to the level of system platform automated monitoring, so the traditional underground pipeline functional safety has also changed from pure physical function security protection to coupled security protection with network system security. In the industrial system application of urban pipeline units, there are many types of equipment and large quantities. In the disaster prevention problem, the uncontrollable hidden dangers brought by the system itself also introduce new safety problems. The traditional physical functional safety concept and protection methods are no longer suitable for the current underground pipeline safety protection methods for natural disasters. Once a security incident caused by a natural disaster occurs, power outages, water outages, gas outages, and information and communication interruptions will cause major accidents that affect urban social security. How to provide an intrinsic safety method for natural disasters for underground pipelines to cope with the unknown threats brought by uncertainty in natural disaster scenarios, and solve the problems based on pipeline functional safety, natural disaster recovery safety, and system information security that are intertwined and difficult to deal with separately, is an urgent problem that needs to be solved to ensure the safety and reliability of urban underground pipelines.

[0004] Therefore, an intrinsic safety system for natural disasters of underground pipelines is proposed. Summary of the invention

[0042] The linkage defense module is used to perform linkage defense based on the received disaster value.

[0043] In order to specifically illustrate the natural disaster intrinsic safety system for underground pipelines of the present invention, a detailed description is given below;

[0044] The safety monitoring module is used to collect safety monitoring data of underground pipelines and provide the safety monitoring data to the pipeline status identification module, the reconfigurable mimicry simulation module and the pipeline network disaster reverse reconstruction module according to categories;

[0045] In this embodiment, the safety monitoring module includes a functional safety monitoring unit, which is used to collect pipeline operation data in real time and send it to the pipeline status discrimination module, providing data support for the pipeline status discrimination module. The safety monitoring module includes a disaster recovery safety monitoring unit, which is used to collect natural disaster-related data in real time and provide the natural disaster data to the reconfigurable mimicry simulation module and the disaster reverse reconstruction module. The safety monitoring module includes an information security monitoring unit, which is used to monitor and collect the information security data of the underground pipeline system to obtain the underground pipeline information security data and send it to the reconfigurable mimicry simulation module.

[0046] The pipeline status discrimination module is used to discriminate the pipeline status and obtain the pipeline status data, and then provide the pipeline status data to the reconfigurable mimicry simulation set;

[0047] In this embodiment, the pipeline status discrimination module discriminates the received pipeline operation data to obtain the pipeline status data; the pipeline status data includes the pipeline environment status, the pipeline body status, and the pipeline medium status.

[0048] The reconfigurable mimicry simulation module is used to perform mimicry on the received pipeline status data and safety monitoring data to obtain n reconfigurable mimicry simulation models, and send the n reconfigurable mimicry simulation models to the multi-mode adjudication module;

[0049] In this embodiment, the reconfigurable mimicry simulation module is specifically used for:

[0050] Dividing the received pipeline status data and safety monitoring data into m sets with reconfigurable operation scenario elements; among them, the reconfigurable operation scenario elements in each set are different; allocating the m sets with reconfigurable operation scenario elements to n mimicry simulation models, where n < m; then, under the constraint of the safety function, performing mimicry transformation on the elements of the n mimicry simulation models to obtain n reconfigurable mimicry simulation models, and sending the n reconfigurable mimicry simulation models to the multi-mode adjudication module.

[0051] In this embodiment, the reconfigurable mimicry simulation set is a set with m reconfigurable operation scenario elements of equivalent functions, and there are safety risk elements with different (differential mode) properties from other elements in any simulation scenario element j (j = 1, 2,..., m). For any input element, the simulation set is allocated to the n mimicry simulation models currently in operation (n < m) through the input agent.

[0052] Furthermore, the mimicry transformation is to perform mimicry transformation on the functional safety, information safety, and disaster recovery safety of urban underground pipelines according to the idea of endogenous security.

[0053] Specifically, the mimetic transformation can be defined as: σ:Ω(t i )→Ω(t i+1 ) The domain of this transformation is the set Ω consisting of all states of urban underground pipelines. Different transformation methods for different elements correspond to different transformations, so σ={σ1,σ2,…,σn}, where σ1 represents the pseudo-transformation of the first element, and the others are deduced in the same way. If Ω(t) is represented by a 0,1 sequence, then σ can be regarded as a scrambling sequence, and different scrambling sequences correspond to different transformations.

[0054] In this embodiment, the definition domain for performing mimetic transformation on the elements of the n mimetic simulation models is the elements in the set of all elements with reconfigurable running scenarios.

[0055] In this embodiment, the safety function specifically includes:

[0056] Underground pipeline safety function function: pf(Ω(t,σ))≤a, where Ω represents the set of reconfigurable operation scenario elements, pf represents the underground pipeline safety function operation on all sets; a is the underground pipeline function safety level coefficient; t represents the number, σ represents the mimetic transformation; Ω(t,σ) represents the set of the tth reconfigurable operation scenario elements;

[0057] Disaster preparedness, safety and defense resource allocation security function: sr(Ω(t,σ))≤b, where sr represents the disaster preparedness, safety and defense resource allocation security calculation for all sets, and b is the disaster preparedness, safety and defense resource allocation security level;

[0058] Information security function of underground pipeline system: mt(Ω(t,σ))≤c, where mt represents the security function operation on all sets, and c is the network security level coefficient.

[0059] The multi-mode decision module is used to simulate and calculate the disaster value based on n reconfigurable mimetic simulation models; if the disaster value is greater than the threshold, the disaster value is sent to the linkage defense module; if the disaster value is less than the threshold, the disaster value is sent to the disaster reverse reconstruction module as the supporting data of the disaster reverse reconstruction module;

[0060] The pipeline network disaster reverse reconstruction module is used to receive the disaster value and perform data correction on the reconfigurable mimic simulation module and the multi-mode decision module based on the disaster value and the natural disaster situation;

[0061] In this embodiment, the pipeline disaster reverse reconstruction module is specifically used for: when a natural disaster occurs, the pipeline disaster reverse reconstruction module starts the underground pipeline disaster reverse reconstruction model to calculate the disaster value. When the calculation result of the underground pipeline disaster reverse reconstruction model is inconsistent with the calculation result of the judgment module, the pipeline disaster reverse reconstruction module corrects the natural disaster-related data and thresholds of the multi-mode judgment module and the reconfigurable mimetic simulation module.

[0062] The linkage defense module is used to perform linkage defense based on the received disaster value.

[0063] In this embodiment, the linkage defense module performs linkage defense based on the received disaster value, specifically including: safety protection of the underground pipeline system, adjustment of the functional load of the underground pipeline, structural reinforcement, and establishment of an emergency response plan.

[0064] "Mimetic defense" through mimetic simulation and multi-mode iterative judgment can effectively separate the internal and external structures of the model, thereby maintaining the independence of the system's endogenous security. The two sides of the "mimetic defense" system are logically independent. The core idea of ​​endogenous security based on mimetic defense is to make heterogeneous redundant executors have dynamic and randomized properties through dynamic switching of functional equivalents, thereby resisting disaster threats. At the same time, the "mimetic defense" system is constantly corrected through disaster reverse reconstruction and tracing, realizing the negative feedback correction function of the architecture.

[0065] like Figure 2 As shown, the present application also designs an intrinsic safety architecture for natural disasters of underground pipelines based on the above-mentioned intrinsic safety system model for natural disasters of underground pipelines.

[0066] Furthermore, the inherent safety architecture of natural disasters for underground pipelines includes five parts: situation awareness layer, risk assessment layer, multi-mode decision layer, linkage defense layer and reverse reconstruction regulation layer.

[0067] Furthermore, the situation awareness layer will collect the functional safety status data, disaster recovery safety status data, and information security status data of underground pipelines in real time, and the situation awareness layer will provide the safety status data and fault data to the risk assessment layer.

[0068] Furthermore, the risk assessment layer utilizes various reconfigurable mimetic simulation models of underground pipelines, including environmental risk mimetic models, pipeline body risk mimetic models, pipeline medium risk mimetic models, and pipeline overall health assessment models, to construct a comprehensive pipeline natural disaster risk assessment system from five aspects: risk law analysis and simulation, standard data construction, multi-dimensional coupling analysis, comprehensive evaluation and service, and standard specification construction. The risk assessment layer then provides the assessment results to the multi-mode decision layer.

[0069] Furthermore, the multi-mode decision-making layer will iteratively calculate the evaluation results, including accident analysis of underground pipelines, regulation of operation and maintenance matters, retrieval of disaster recovery plans, and emergency deployment arrangements to provide decision support for joint defense.

[0070] Furthermore, the linkage defense layer implements multiple defense measures such as safety protection, underground pipeline functional load adjustment, structural reinforcement and emergency response for the underground pipeline system.

[0071] Furthermore, the reverse reconstruction regulation layer provides data correction support for the situation awareness layer, risk assessment layer and multi-mode decision layer, and the protection adjustment data of the multi-mode decision layer and the disaster data of the situation awareness layer are also synchronously provided to the reconstruction regulation layer to provide data support for conditional correction of disaster reconstruction and tracing.

[0072] Furthermore, the underground pipeline natural disaster intrinsic safety architecture is a dynamic heterogeneous redundant architecture with a generalized robust control mechanism, that is, it simulates sudden disasters through continuous changes using reconfigurable mimetic simulation.

[0073] The core of the present invention is to introduce the theory of intrinsic safety, and its key idea focuses on "change". Specifically, a dynamic heterogeneous redundant architecture with a generalized robust control mechanism is constructed, which is realized through mimicry technology. This architecture relies on reconfigurable mimicry simulation to simulate sudden disaster scenarios. With the help of functionally equivalent dynamic switching operations, the heterogeneous redundant architecture is endowed with significant attributes of dynamicity and adaptability. In the actual operation process, the functional safety, information security and disaster recovery safety of the pipeline are fully considered, and a reconfigurable mimicry simulation model is used for all-round monitoring and analysis. Once a potential disaster risk is detected or a disaster has been attacked, the system can quickly start the disaster reverse reconstruction mechanism and accurately correct the defense strategy based on the real-time collected data. Through this innovative design, an adaptive, dynamic and diversified defense strategy is realized under both normal and emergency conditions, which can efficiently identify and effectively respond to various safety risks brought by disasters to pipelines, etc., greatly improving the overall safety and stability of the system.

[0074] The present invention proposes an intrinsic safety method for urban underground pipelines, which introduces sudden mimetic defense on the basis of traditional safety management, and performs mimetic defense on random risks such as pipeline functional safety, natural disaster recovery safety, and system information security. It constructs an integrated urban lifeline intrinsic safety system and architecture of "information security-functional safety-disaster recovery safety", so that the underground pipeline system can provide early warning of abnormal disaster hazards in underground pipelines, effectively reducing the unknown threats brought by uncertainty in natural disaster scenarios, and improving the safety and reliability of urban underground pipelines.

[0075] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
