Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a signal management method, apparatus, electronic device, and computer-readable storage medium. Background Technology

[0002] In the field of nuclear power plant engineering management, when a power plant undergoes extensive renovations or upgrades, there are often numerous adjustments and changes to interface signals. These interface signals are typically interconnected signals between multiple systems, with a wide range of changes and complex interactions between systems.

[0003] Traditional technical solutions typically involve manually identifying and recording modified interface signals. This method has several shortcomings: First, manual identification is prone to omissions or errors in signal recording, leading to signal mismatches or linkage errors between systems. Second, it is difficult to comprehensively check the compatibility of signal interfaces between multiple modification schemes, especially when the modification scope is wide and the systems involved are complex, easily resulting in inconsistencies in interface signals. Third, in the re-qualification and testing procedures, there is a lack of a systematic method to ensure that all newly added and related modified interface signals are fully verified, easily leading to omissions or insufficient testing. In addition, traditional risk identification and verification mainly rely on experience-based judgment, lacking algorithmic support, resulting in low efficiency and insufficient reliability. These problems seriously affect the safety and reliability of nuclear power plant retrofitting. Summary of the Invention

[0004] This application provides a signal management method, apparatus, electronic device, and computer-readable storage medium, which can automatically identify signal changes and manage signals, improving the comprehensiveness and accuracy of signal verification, thereby enhancing the quality and efficiency of nuclear power plant retrofit projects.

[0005] Firstly, this application provides a signal management method applied to a signal management device. The method includes: acquiring at least one image to be identified, the image carrying change information and attribute information of interface signals; extracting the change information and attribute information of interface signals from the at least one image to be identified based on a preset recognition model, obtaining multiple change signals and multiple attribute information, wherein the multiple change signals correspond one-to-one with the multiple attribute information; performing consistency verification on the multiple change signals using the multiple attribute information based on a historical signal database, obtaining multiple verification results, wherein the multiple verification results correspond one-to-one with the multiple change signals; a first verification result is used to characterize whether a first change signal is consistent with a first historical signal; the first change signal is any one of the multiple change signals; the first verification result is the one among the multiple verification results corresponding to the first change signal; and the first historical signal is the signal in the historical signal database corresponding to the first change signal. If the first verification result indicates that the first change signal is inconsistent with the first historical signal, a first prompt message is displayed, the first prompt message indicating that the first change signal is inconsistent with the first historical signal.

[0006] In some implementations, after performing consistency verification on multiple change signals using multiple attribute information, the method further includes: performing path verification on the second change signal and the third change signal based on a preset pattern recognition model using multiple attribute information to obtain a first path verification result. The second change signal is any one of the multiple change signals as an input signal, and the third change signal is the output signal corresponding to the second change signal among the multiple change signals. The first verification result is used to characterize whether the path between the second change signal and the third change signal is complete.

[0007] In some implementations, after the step of verifying the path of the second change signal and the third change signal based on a preset pattern recognition model and using multiple attribute information to obtain a first path verification result, the method further includes: if the first path verification result indicates that the path between the second change signal and the third change signal is incomplete, then outputting a second prompt message, the second prompt message being used to indicate that the path between the second change signal and the third change signal is incomplete.

[0008] In some implementations, after performing consistency verification on multiple change signals using multiple attribute information, the method further includes: determining a first risk assessment probability corresponding to the first change signal based on multiple verification results using a preset risk assessment model. If the first risk assessment probability is less than the preset risk probability, a third prompt message is output, which indicates that risk intervention measures need to be taken for the first change signal.

[0009] In some implementations, after performing consistency verification on multiple changed signals using multiple attribute information, the method further includes: determining a signal coverage rate based on the number of covered interface signals and the corresponding number of multiple changed signals using a preset coverage verification algorithm. The signal coverage rate is positively correlated with the number of covered interface signals and negatively correlated with the corresponding number of multiple changed signals. If the signal coverage rate is less than a preset signal coverage rate threshold, a fourth prompt message is output to prompt the user to perform a secondary signal verification.

[0010] In some implementations, the signal is a new signal, an adjustment signal, or a deletion signal.

[0011] In some implementations, the preset recognition model is a language processing model and / or an image recognition model.

[0012] Secondly, this application provides a signal management device, which includes: an acquisition module and a processing module;

[0013] The acquisition module is used to acquire at least one image to be identified, which carries change information and attribute information of the interface signals.

[0014] The processing module is used to extract change information and attribute information of interface signals from at least one image to be identified based on a preset recognition model, so as to obtain multiple change signals and multiple attribute information, with each change signal corresponding to one of the multiple attribute information.

[0015] The processing module is also used to perform consistency verification on multiple changed signals based on a historical signal database, using multiple attribute information to obtain multiple verification results. Each verification result corresponds one-to-one with a changed signal. The first verification result indicates whether the first changed signal is consistent with the first historical signal. The first changed signal is any one of the multiple changed signals, and the first verification result is the one corresponding to the first changed signal among the multiple verification results. The first historical signal is the signal in the historical signal database that corresponds to the first changed signal. If the first verification result indicates that the first changed signal is inconsistent with the first historical signal, a first prompt message is displayed, indicating that the first changed signal is inconsistent with the first historical signal.

[0016] Thirdly, this application provides a chip for performing the methods described in any of the first aspects above.

[0017] Fourthly, this application provides an electronic device including a processor and a memory, the processor being configured to execute a computer program stored in the memory to implement the method as described in any of the first aspects above. Alternatively,

[0018] Electronic devices include chips, as described in the third aspect.

[0019] Fifthly, this application provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the method as described in any of the first aspects above.

[0020] In a sixth aspect, this application provides a computer program product storing a computer program that, when executed by a processor, implements the method as described in any of the first aspects above.

[0021] In the technical solution provided in this application, the signal management device can acquire at least one image to be identified, which carries change information and attribute information of the interface signal. Based on a preset recognition model, the change information and attribute information of the interface signal are extracted from each of the at least one image to be identified, resulting in multiple changed signals and multiple attribute information, with each changed signal corresponding to one of the multiple attribute information. Based on a historical signal database, the consistency of the multiple changed signals is verified using the multiple attribute information, resulting in multiple verification results, each corresponding to one of the multiple changed signals. The first verification result indicates whether the first changed signal is consistent with the first historical signal. The first changed signal is any one of the multiple changed signals, the first verification result is the one corresponding to the first changed signal among the multiple verification results, and the first historical signal is the signal corresponding to the first changed signal in the historical signal database. If the first verification result indicates that the first changed signal is inconsistent with the first historical signal, a first prompt message is displayed, indicating that the first changed signal is inconsistent with the first historical signal. The technical solution provided in this application can automatically identify signal changes and manage signals, improving the comprehensiveness and accuracy of signal verification, thereby improving the quality and efficiency of nuclear power plant retrofit projects.

[0032] In the field of nuclear power plant engineering management, overhaul or major technical upgrade projects often involve the adjustment and change management of interface signals across multiple systems and disciplines. These interface signals serve as crucial links for information exchange between systems, and the effectiveness of their change management directly impacts the smooth implementation of the power plant upgrade project and its subsequent safe operation. Therefore, establishing a systematic interface signal change identification mechanism is a key control element in the quality management system of nuclear power plant upgrade projects.

[0033] In traditional technical solutions, the identification of interface signals mainly relies on traditional manual verification methods. However, nuclear power plant control and management systems have the following characteristics:

[0034] Feature 1: The number of signal interfaces is large and they are widely distributed.

[0035] Feature 2: Complex cross-system signal interaction relationships.

[0036] Feature 3: The signal changes involved in the renovation project have a chain effect.

[0037] Therefore, traditional manual verification methods have significant technical limitations. Specifically:

[0038] Limitation 1: Incomplete signal change tracing can easily lead to the omission of critical input or output signals, resulting in signal mismatch or incorrect linkage between systems.

[0039] For example, in traditional technical solutions, recording the signal types supported by multiple devices requires manual review of multiple design documents, drawings, and maintenance records, followed by manual compilation and input into the signal management device. Due to the dispersed nature of design documents and issues such as inconsistent versions or delayed updates, document compilation is quite difficult. Cross-system signals in the documents are easily overlooked, such as the linkage signals between the nuclear island control system and distributed systems. Manual identification makes it difficult to locate the physical connection between signal transmitters (such as pressure transmitters) and receivers (such as safety protection systems).

[0040] Limitation 2: Insufficient impact assessment of related systems. The lack of a systematic approach in the re-evaluation and testing procedures makes it difficult to ensure that all newly added and related modified interface signals are fully verified, which can easily lead to omissions or insufficient testing.

[0041] For example, equipment modifications (such as replacing circuit boards) may cause changes in electrical parameters (e.g., output impedance changing from 50Ω to 75Ω). If the input impedance at the receiving end is mismatched (e.g., originally designed for 50Ω), it can lead to signal attenuation or distortion. Relying on manual parameter checks can easily overlook hidden problems (e.g., impedance mismatch in high-frequency signals). When multiple systems are linked (e.g., temperature systems and security systems), it is difficult to fully verify all interfaces.

[0042] Limitation 3: The accuracy of change records is difficult to guarantee, and the compatibility of signal interfaces between multiple modification schemes is difficult to fully check. This is especially true when the scope of modification is wide and the system involved is complex, which can easily lead to inconsistencies in interface signals.

[0043] During signal transmission, the impedances at both ends of a 50Ω coaxial cable must be consistent. That is, the output impedance sent by the transmitting end and the input impedance received by the receiving end must be consistent. If the signals are inconsistent, it will lead to signal reflection (waveform distortion) or power loss.

[0044] These defects can easily lead to signal mismatch between the modified systems, resulting in serious consequences such as abnormal system linkages, posing potential risks to the safe and stable operation of nuclear power plants. This situation highlights the inadequacy of traditional management methods in dealing with changes in complex systems engineering, necessitating the introduction of more advanced digital management tools for improvement.

[0045] In view of this, this application provides a signal management method that can automatically identify signal changes and manage signals, thereby improving the comprehensiveness and accuracy of signal verification and thus enhancing the quality and efficiency of nuclear power plant retrofit projects.

[0046] This application provides a schematic diagram of a signal management process for a signal management method, as shown in the embodiments below. Figure 1 As shown, the signal management process of the signal management device may include the following steps:

[0047] Step S101: Obtain at least one image to be identified, which carries change information of the interface signal and attribute information of the interface signal.

[0048] In this embodiment of the application, the image to be identified may be a modification scheme text or a design document, and this application does not limit it.

[0049] The change information for the interface signals can be multiple modified signals among multiple interface signals corresponding to at least one image to be recognized, indicating that the signals have changed. For example, the multiple modified signals can include one or more of the following: added signals, adjusted signals, and deleted signals.

[0050] The attribute information for each interface signal can include at least the signal type, signal parameters, the signal transmitting device, the signal receiving device, the signal purpose, and the associated system.

[0051] The signal type can be analog signal, digital signal, communication protocol, or logic interlock signal. Analog signal can be a 4-20mA temperature signal, digital signal can be a switching signal, communication protocol can be Modbus protocol (a serial communication protocol), and logic interlock signal can be a stop trigger signal.

[0052] Signal parameters can include: impedance requirements, voltage range, current range, and timing requirements. Impedance requirements can be a specific impedance value, such as 50Ω. The voltage range can be 0-10V, and the timing requirements can be a response time ≤100ms.

[0053] The signal transmitting device can be a temperature sensor or a pressure transmitter.

[0054] The signal receiving device can be a nuclear island control system (DCS) or a security system interlocking module.

[0055] The purpose of a signal is to characterize its function. For example, a temperature signal might be used for a "reactor coolant over-temperature alarm".

[0056] Correlation systems can be used to characterize the scope of a signal's influence. For example, signal A may affect both a security system and a control room display system.

[0057] For example, a signal with signal ID T-001, signal type is analog signal, signal transmitting device is reactor thermometer, signal receiving device is nuclear island control system (DCS), current range is 4-20mA, impedance requirement can be ≤100Ω, and associated system is nuclear island control system (DCS) and security system interlocking module.

[0058] Step S102: Based on the preset recognition model, extract the change information and attribute information of the interface signal from at least one image to be recognized, and obtain multiple change signals and multiple attribute information, with each change signal corresponding to one of the multiple attribute information.

[0059] In this embodiment of the application, the preset recognition model can be a language processing model and / or an image recognition model.

[0060] Language processing models can be based on NLP (Natural Language Processing).

[0061] Specifically, the signal management device can parse multiple modified signals and attribute information of the interface signals in the modification plan text using a language processing model. It then utilizes a signal topology map (graph database) to automatically retrieve interface signals directly or indirectly connected to the modified equipment (such as the signal path output by the temperature sensor). Based on signal dependencies, it identifies affected upstream and downstream signals (such as security interlock logic triggered by the temperature signal).

[0062] Rules for determining whether a signal is affected: Direct correlation: The signal transmitting or receiving equipment has been modified; Indirect correlation: The system on which the signal logic depends has changed (such as the adjustment of the interlocking threshold of a security system).

[0063] For example, if the controller of a pump is replaced in the retrofit plan, the system will automatically mark all input signals (such as flow meter signals) received by the controller and control signals (such as pump start / stop commands) output by the controller as "affected signals".

[0064] The signal management device can extract all interface signals and their related attributes from design documents, engineering drawings, and modification plans using language processing models and image recognition models.

[0065] For example, a modification scheme involving signal adjustment is described as "adding a new signal and changing the original signal to draw power from the new power supply LNN". The system can identify the new signal, the adjusted signal and their corresponding power path relationship, avoiding omissions and misjudgments caused by manual identification.

[0066] For example, the newly added signal in A is S. A ={s a1 ,s a2 The signal for the B modification and adjustment is S. B ={s b1 ,s b2 ,s b3}

[0067] Modification A is used to characterize: adding a new temperature signal (such as T-New) to monitor the newly installed cooling equipment.

[0068] Modification B is used to characterize: adjusting the output range of the original pressure signal (such as P-Old) (e.g., changing it from 0-10V to 4-20mA).

[0069] s a1 It can represent a temperature signal (such as T-New) used to monitor newly installed cooling equipment, or it can be other newly added monitoring parameters.

[0070] s b1 It may correspond to the original pressure signal (such as P-Old), but the parameters (such as the output range from 0–10V to 4–20mA) have been adjusted.

[0071] From each modification scheme, the system will extract the relevant signal set S. A S B For example, for each signal, the system identifies its operational type within the modification scheme:

[0072] New addition: Exists in the renovation plan but not in the historical database (e.g., T-New added in renovation A).

[0073] Adjustment: There are inconsistencies in parameters between the modified scheme and the signals with the same name in the historical database (for example, modification B modifies the output range of P-Old).

[0074] Delete: Exists in the historical database but is not mentioned in the renovation plan (e.g., discarded sensor signal S-Del).

[0075] Based on this, the signal management device can obtain the signal name and record the attributes, parameters and operation type of each signal.

[0076] Step S103: Based on the historical signal database, perform consistency verification on multiple change signals using multiple attribute information to obtain multiple verification results. Each verification result corresponds to one of the multiple change signals. The first verification result is used to characterize whether the first change signal is consistent with the first historical signal. The first change signal is any one of the multiple change signals. The first verification result is the one of the multiple verification results that corresponds to the first change signal. The first historical signal is the signal in the historical signal database that corresponds to the first change signal.

[0077] In this embodiment, the signal management device can perform consistency verification on multiple changed signals to ensure the synchronization of interface signal adjustments between multiple system upgrades. This improves the correctness and completeness of changed signal checks. Specifically, it can verify whether the signal parameters, signal uses, and timing requirements of multiple changed signals are compatible with the signal management systems before and after the changes.

[0078] For example, the original signal parameters could be an impedance of 50Ω and a voltage range of 0-5V. The subsequent signal management system parameters could be an output impedance of 75Ω. The signal management device can use a rule engine to verify the compatibility of impedance and voltage / current ranges (e.g., whether the transmitting end's output impedance is less than or equal to the receiving end's input impedance). If the transmitting end's impedance is 75Ω and the receiving end's input impedance is 50Ω, an "impedance mismatch" alarm will be triggered. The tool supports checking whether the signal logic is consistent with the system design (e.g., whether an over-temperature signal can still correctly trigger the security interlock). It also supports simulating signal transmission using a digital twin model to verify the logic's correctness. Finally, it ensures cross-system signal timing matching (e.g., a valve closing signal needs to be fed back to the control system within 2 seconds).

[0079] For example, if the modifications to A and B involve a common signal s x The signal management system in the signal management device can verify whether the signal status is modified synchronously in the two modifications and whether there are any logical contradictions. If an inconsistency is found, the signal management device will display a prompt message to remind the engineer to adjust the design scheme. The verification formula can be: C(s) x )=(s x ∈S orig )←→(s x ∈S mod );

[0080] Among them, s x S represents a common signal. origS represents the set of signals in the historical database. mod This represents the set of signals in the modification plan (which may include newly added or adjusted signals). ←→ indicates a two-way condition or a "if and only if" data relationship.

[0081] This formula is used to verify whether the logical relationship of the signals is consistent before and after the modification. If the verification result is C(s) x If ) = false, it means that the logical relationship of the signals before and after the modification is inconsistent, and the signals do not match in the historical state and the modified state. A modification plan is required. The signal management device will then display a prompt message to indicate that there is an inconsistency in the signals involved in the modifications of A and B.

[0082] Step S104: If the first verification result indicates that the first change signal is inconsistent with the first historical signal, then the first prompt information is displayed. The first prompt information is used to indicate that the first change signal is inconsistent with the first historical signal.

[0083] In the technical solution provided in this application embodiment, the signal management device can acquire at least one image to be identified, which carries change information and attribute information of the interface signal. Based on a preset recognition model, the change information and attribute information of the interface signal are extracted from the at least one image to be identified, resulting in multiple changed signals and multiple attribute information, with each changed signal corresponding to one of the multiple attribute information. Based on a historical signal database, the consistency of the multiple changed signals is verified using the multiple attribute information, resulting in multiple verification results, each corresponding to one of the multiple changed signals. The first verification result indicates whether the first changed signal is consistent with the first historical signal. The first changed signal is any one of the multiple changed signals, the first verification result is the one corresponding to the first changed signal among the multiple verification results, and the first historical signal is the signal corresponding to the first changed signal in the historical signal database. If the first verification result indicates that the first changed signal is inconsistent with the first historical signal, a first prompt message is displayed, indicating that the first changed signal is inconsistent with the first historical signal. The technical solution provided in this application embodiment can automatically identify signal changes and manage signals, improving the comprehensiveness and accuracy of signal verification, thereby improving the quality and efficiency of nuclear power plant retrofit projects.

[0084] In some embodiments, the signal management device can also perform path verification on the second changed signal and the third changed signal based on a preset pattern recognition model and multiple attribute information to obtain a first path verification result. The second changed signal is any one of the multiple changed signals as an input signal, and the third changed signal is the output signal corresponding to the second changed signal among the multiple changed signals. The first verification result is used to characterize whether the path between the second changed signal and the third changed signal is complete. If the first path verification result indicates that the path between the second changed signal and the third changed signal is incomplete, a second prompt message is output, which is used to characterize the incomplete path between the second changed signal and the third changed signal.

[0085] Specifically, the signal management device can use pattern recognition technology to check the matching of input and output signals in the modification plan. This helps determine whether the path between input and output signals is complete. The signal management device can determine the matching relationship between input and output signals in the modification plan, that is, whether the signal transmission path is complete. For each input signal, there must be a corresponding output signal, and this output signal must be obtained after passing through a signal conversion function. If each input signal has a corresponding output signal, and the entire transmission path (from sensor signal acquisition, conversion, and transmission to the controller or actuator) is complete, the signal management device considers it a match. If an input signal cannot find a corresponding output signal, or if the signal conversion function is missing or the parameters are mismatched, it indicates that there may be a risk of signal path breakage. The signal management device can display prompts to remind engineers to revise the modification plan.

[0086] For example, a signal transmission path might be: sensor (s_input) → signal conversion function f() → controller → actuator (s_output). The signal management device can verify whether the input signal acquired from the sensor can find a corresponding output signal after passing through the conversion function f(). If a match is not found at any stage, the signal management device displays a warning message indicating a risk of signal path breakage.

[0087] For example, if a certain signal path in the modification scheme is s input →s output The system must ensure that:

[0088] Where, f(s) i ) is the signal transformation function. If a matching signal cannot be found, the signal management device will display a prompt message indicating the risk of signal path breakage.

[0089] The signal management device can identify potential issues such as inconsistent signal states or broken paths when multiple modifications are performed in parallel, and promptly prompt engineers to adjust the modification plan, thereby avoiding logical conflicts and system risks caused by asynchronous signal states.

[0090] In some embodiments, the signal management device can also perform a coverage check. The signal management device can determine the signal coverage rate based on the number of covered interface signals and the number of corresponding multiple modified signals, using a preset coverage verification algorithm. The signal coverage rate is positively correlated with the number of covered interface signals and negatively correlated with the number of corresponding multiple modified signals. If the signal coverage rate is less than a preset signal coverage rate threshold, a fourth prompt message is output to prompt the user to perform a secondary signal verification.

[0091] Specifically, the signal management device can analyze the re-evaluation and testing procedures using intelligent algorithms to ensure that all newly added and related interface signals involved in the modification are within the verification range. This ensures that the re-evaluation and testing procedures cover all newly added and affected interface signals, including: signal transmission under normal operating conditions; boundary conditions (such as signal over-limit or disconnection faults); and cross-system linkage scenarios (such as temperature signal triggering security interlocks).

[0092] For example, the formula for signal verification coverage can be:

[0093] Where V represents coverage, |S verified | Indicates the number of interface signals covered in the test procedure, that is, the number of signals actually tested during the verification process. |S total | represents the total number of all signals requiring verification identified in step one, including newly added signals, adjusted signals, and associated signals. When the calculated coverage rate V is less than 100%, it indicates that some signals have not been tested and verified. The signal management device will then automatically generate a prompt, reminding engineers to supplement the verification plan to ensure that all signals involved in the modification are fully covered, preventing omissions that could lead to potential risks.

[0094] It can prevent high-risk signals (such as safety interlock signals) from being unverified due to missing test cases, ensuring the functional integrity and security of the modified system.

[0095] In some embodiments, the signal management device may also incorporate machine learning and logic verification algorithms to optimize the efficiency and accuracy of interface signal recognition and verification.

[0096] In some embodiments, the signal management device may also determine a first risk assessment probability corresponding to the first change signal based on multiple verification results and a preset risk assessment model. If the first risk assessment probability is less than the preset risk probability, a third prompt message is output, which indicates that risk intervention measures need to be taken for the first change signal.

[0097] Signal management devices can establish a dynamic risk assessment model based on Bayesian networks and analyze the risks that signal modifications may introduce in real time. The dynamic risk assessment model can analyze the evolution of risks during signal modification in real time. A Bayesian network is a probabilistic graphical model used to express the conditional dependencies between variables and update the risk probabilities of each variable based on known data.

[0098] signal s i The risk calculation formula is as follows: P(s) i ) = P hist (s i )×P mod (s i );

[0099] If P(si) > the threshold, the renovation plan needs to be adjusted or additional risk control measures need to be taken. The relevant renovation construction process should be stopped.

[0100] For example, in the interface signal verification process of modification A and modification B, the signal operations of modification A and modification B are different. Modification A mainly adds new signals, while modification B mainly adjusts existing signals.

[0101] s x This refers to a common signal involved in both modification A and modification B. It is a related signal that needs to be modified or kept consistent in both modification schemes.

[0102] Correlated signals ensure logical consistency across different modification schemes when modifying the same signal, preventing system anomalies caused by signal mismatches. For example, in the example, if a signal is defined as "drawing power from the old power supply LNM" in modification A, but as "drawing power from the new power supply LNN" in modification B, inconsistencies will arise, requiring adjustments.

[0103] Therefore, it represents a signal that both schemes are concerned with or modifying. The essence of the associated signal is to associate the operations involving the same interface signal in different modifications, so as to ensure that the entire system maintains consistent interface logic after the modification.

[0104] Assume A modifies and adds a new signal S A ={s a1 ,s a2 The signal for the B modification and adjustment is S. B ={sb1 ,s b2 ,s b3}, and the correlation signal between the two is s x After the signal management device automatically extracts the signals, it identifies that both A and B require modification. Generally, adding or adjusting signals only modifies the common parts between the two, without affecting their independent parts.

[0105] Specifically, modification A adds a new signal, meaning it introduces a new signal into the existing system without altering the settings of existing signals (unless explicitly stated otherwise). Modification B adjusts a signal, meaning it modifies existing signals but does not affect the new signal. If both modification A and modification B involve the same signal s... x Then the signal management device needs to determine s x The definitions in the two modifications must be consistent; otherwise, a logical conflict will arise.

[0106] After the signal management device automatically extracts the modification plan, if it detects that a signal is defined as "drawing power from the old power supply LNM" in modification A, but defined as "drawing power from the new power supply LNN" in modification B, the consistency verification result indicates a mismatch in signal states, which may lead to abnormal signal paths. Specifically, modification A indicates that signal s x The old LNM power supply is still used as the power source. Modification B indicates signal s... x The system has switched to a new power source, LNN. This will cause s x The different power supply paths may cause signal abnormalities.

[0107] For example, if s x Defined as drawing power from the old power supply LNM, but the LNM has been discarded or replaced, then s x It may not work properly. If some devices still rely on s x Some devices draw power from the old power source, while others rely on the new power source, which may lead to incompatibility between the devices.

[0108] Therefore, the system will display a prompt message, indicating that... x The signal paths are inconsistent, and the modification plans for A and B need to be coordinated to ensure that s x The definition is consistent.

[0109] For example, the renovation plan involves adding a new signal S. new ={s n1 ,s n2}, associated signal S rel ={s r1 ,s r2 ,s r3 The signal management device detected the corresponding coverage rate. If the probability of the first risk assessment is less than the preset risk probability, the signal management device will display a prompt message indicating that risk intervention measures need to be taken for the first change signal.

[0110] It should be understood that, provided there are no logical conflicts, the above-described embodiments can be combined and implemented to adapt to actual application needs. These combined embodiments or implementation schemes are still within the scope of protection of this application.

[0111] Corresponding to the signal management method in the above embodiments, this application provides a signal management device, which can be implemented as part or all of a computer device by software, hardware or a combination of both, and is used to execute the steps in the signal management method in the above embodiments.

[0112] Figure 2 A schematic diagram of the structure of a signal management device 20 provided in an embodiment of this application is shown. For ease of explanation, only the parts related to the embodiment of this application are shown.

[0113] Reference Figure 2 The device 20 includes an acquisition module 210 and a processing module 220.

[0114] The acquisition module 210 is used to acquire at least one image to be identified, the image to be identified carrying change information of the interface signal and attribute information of the interface signal.

[0115] The processing module 220 is used to extract change information and attribute information of interface signals from at least one image to be identified based on a preset recognition model, so as to obtain multiple change signals and multiple attribute information, with each change signal corresponding to one of the multiple attribute information.

[0116] The processing module 220 is further configured to perform consistency verification on multiple changed signals based on a historical signal database, using multiple attribute information entries to obtain multiple verification results. Each verification result corresponds one-to-one with a changed signal. A first verification result indicates whether a first changed signal is consistent with a first historical signal. The first changed signal is any one of the multiple changed signals, and the first verification result is the one corresponding to the first changed signal among the multiple verification results. The first historical signal is the signal in the historical signal database that corresponds to the first changed signal. If the first verification result indicates that the first changed signal is inconsistent with the first historical signal, a first prompt message is displayed, indicating that the first changed signal is inconsistent with the first historical signal.

[0117] In some embodiments, the processing module 220 is further configured to: perform path verification on the second change signal and the third change signal based on a preset pattern recognition model and through multiple attribute information to obtain a first path verification result, wherein the second change signal is any one of the multiple change signals as an input signal, and the third change signal is the output signal corresponding to the second change signal among the multiple change signals, and the first verification result is used to characterize whether the path between the second change signal and the third change signal is complete.

[0118] In some embodiments, the processing module 220 is further configured to: if the first path verification result indicates that the path between the second change signal and the third change signal is incomplete, output a second prompt message, the second prompt message being used to indicate that the path between the second change signal and the third change signal is incomplete.

[0119] In some embodiments, the processing module 220 is further configured to: determine a first risk assessment probability corresponding to the first change signal based on multiple verification results using a preset risk assessment model. If the first risk assessment probability is less than the preset risk probability, then output a third prompt message, which indicates that risk intervention measures need to be taken for the first change signal.

[0120] In some embodiments, the processing module 220 is further configured to: determine the signal coverage rate based on the number of covered interface signals and the number of multiple changed signals using a preset coverage verification algorithm, wherein the signal coverage rate is positively correlated with the number of covered interface signals and negatively correlated with the number of multiple changed signals. If the signal coverage rate is less than a preset signal coverage rate threshold, a fourth prompt message is output, which prompts the user to perform a secondary signal verification.

[0121] In some embodiments, the change signal is an addition signal, an adjustment signal, or a deletion signal.

[0122] In some embodiments, the preset recognition model is a language processing model and / or an image recognition model.
