Description

Technical Field

[0001] This invention relates to the field of building fire safety monitoring and intelligent fire protection technology, specifically to a method and system for monitoring leakage current in building fire protection facilities. Background Technology

[0002] Building fire protection facilities typically include fire pumps, smoke extraction fans, fire elevators, automatic fire alarm systems, emergency lighting equipment, and other fire-fighting linkage control equipment. These devices play a crucial role in fire monitoring, alarm systems, fire suppression, smoke extraction, and personnel evacuation. The continuity of their power supply and the reliability of their operation directly affect the overall emergency response capability of the building's fire protection system. To ensure the stable operation of building fire protection facilities, leakage current monitoring of their power supply circuits is usually necessary to promptly detect abnormalities such as insulation degradation, aging wiring, or electrical faults, thereby reducing the adverse effects of electrical faults on the operation of the fire protection system.

[0003] In existing technologies, leakage current anomaly monitoring of power supply circuits for building fire protection facilities typically relies on whether leakage current, residual current, or other single electrical parameters exceed preset thresholds for judgment, and outputs uniform alarm information or executes corresponding protection measures accordingly. However, this approach usually only judges based on the electrical anomaly itself, failing to comprehensively assess the potential functional impact of leakage current anomalies by considering the task attributes of the fire protection equipment, the fire zone it belongs to, the fire linkage status, and the real-time operating status of the equipment. Especially during fire alarm response, the importance of the tasks undertaken by different fire protection equipment and their continuous power supply requirements vary significantly. If a uniform anomaly judgment and response method is still used, it is easy to cause inaccurate alarm classification, and even affect the continuous power supply and normal operation of critical fire protection equipment, thereby reducing the system safety during fire alarm response.

[0004] Therefore, it is necessary to provide a method and system for monitoring leakage current in building fire protection facilities. After detecting leakage anomalies, the system can classify and assess the impact of the anomalies by combining the task attributes of fire protection equipment, fire zoning relationships, and fire linkage status. Based on this, it can output differentiated alarm prompts or monitoring and control results to improve the accuracy of alarm classification, ensure continuous power supply to critical fire protection equipment, and enhance the safety and reliability of building fire protection systems during fire alarm response. Summary of the Invention

[0005] This invention provides a method and system for monitoring leakage current in building fire protection facilities, which solves the problem that existing technologies mainly rely on a single electrical parameter to judge abnormal leakage current in building fire protection facilities, and it is difficult to combine the task attributes of fire protection equipment, fire zoning relationships and fire linkage status for impact assessment. It achieves the purpose of improving the accuracy of alarm classification, ensuring continuous power supply to key fire protection equipment and improving system safety during fire alarm handling.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] In a first aspect, the present invention provides a method for monitoring leakage current in building fire protection facilities, comprising:

[0008] Based on the power supply topology, equipment wiring, fire zones, and fire linkage configuration of building fire protection facilities, a functional association model between power supply circuits, fire protection equipment, fire zones, fire linkage objects, and equipment task priorities is established or updated in advance.

[0009] Real-time acquisition of electrical anomaly monitoring data, real-time equipment operation feedback data, and fire alarm linkage status data, wherein the electrical anomaly monitoring data includes at least leakage current anomaly signals of the target power supply circuit;

[0010] When the leakage current abnormal signal is detected, the fire equipment object, fire zone, associated fire linkage object and current task status information corresponding to the target power supply circuit are determined based on the functional association model.

[0011] The impact level of the leakage current abnormal signal is determined based on whether the fire-fighting equipment is involved in the current fire linkage task, the equipment task priority, the relationship between the fire zone to which it belongs and the current fire alarm zone, and the real-time operation feedback data of the equipment.

[0012] According to the impact level, corresponding alarm prompts or monitoring and control results are output. For impact situations related to the current fire alarm response task, the monitoring and control results include ensuring the continuous power supply to the corresponding fire-fighting equipment.

[0013] Record the leakage current abnormality signal, its impact level, and the output results.

[0014] Optionally, the functional association model includes:

[0015] The mapping relationships between power supply circuits and fire protection equipment, fire protection equipment and fire zones, fire protection equipment and fire linkage objects, and fire protection equipment and equipment task priorities.

[0016] Optionally, the electrical anomaly monitoring data may include, in addition to leakage current anomaly signals, at least one of insulation anomaly signals and circuit fault status signals.

[0017] Optionally, the current task status information includes: the current operating status of the corresponding fire-fighting equipment, whether it participates in the current fire-fighting linkage task, the current fire-fighting linkage stage, whether it is in an already activated state, and whether it belongs to a task to be activated.

[0018] Optionally, the impact level is determined using a progressive exclusion rule, and includes, from high to low, the critical function risk level, the task execution impact level, the standby capability impact level, and the general electrical anomaly level.

[0019] Among them, fire-fighting equipment with a task priority higher than a preset priority threshold is classified as critical task equipment; when the fire-fighting equipment is critical task equipment, is related to the current fire alarm handling task, and the leakage current abnormal signal may cause the corresponding fire-fighting function to be interrupted, it is determined to be a critical function risk level.

[0020] When the fire-fighting equipment does not meet the criteria for determining the risk level of critical functions, participates in the current fire-fighting linkage task, and the leakage current abnormal signal affects the execution of the current task, it is determined to be at the task execution impact level.

[0021] When the fire-fighting equipment does not meet the criteria for determining the risk level of critical functions and the impact level of task execution, and is not involved in the current fire-fighting linkage task but the leakage abnormal signal affects the subsequent deployment capability, it is determined to be at the standby capability impact level.

[0022] The remaining cases are classified as general electrical anomalies.

[0023] Optionally, the determination of the risk level of the critical function takes precedence over the impact level of task execution, the impact level of standby capability, and the general electrical anomaly level.

[0024] Optionally, the alarm prompts or monitoring and control results include at least one of the following: general abnormality records, maintenance prompts, priority maintenance prompts, manual intervention prompts, high-level early warnings, enhanced monitoring with faults, backup equipment call control commands or call prompts, and backup power supply path call control commands or call prompts.

[0025] Optionally, when the impact level is the task execution impact level or the critical function risk level, the fire-fighting equipment corresponding to the target power supply circuit is controlled to enter the fault-enhanced monitoring mode.

[0026] In the enhanced fault monitoring mode, without cutting off the power supply to the target power supply circuit, the frequency of abnormal monitoring of the target power supply circuit is increased, and the early warning response cycle and / or monitoring data upload cycle are shortened.

[0027] Optionally, the relationship between the fire zone to which the fire-fighting equipment belongs and the current fire alarm zone includes a consistent relationship, a linkage relationship, and an unrelated relationship;

[0028] Among them, the consistency relationship means that the fire zone to which the fire equipment belongs is the same as the current fire alarm zone; the linkage relationship means that although the fire zone to which the fire equipment belongs is different from the current fire alarm zone, there is a preset fire linkage configuration relationship with the current fire alarm zone; and the irrelevant relationship means that there is no preset fire linkage configuration relationship between the fire zone to which the fire equipment belongs and the current fire alarm zone.

[0029] Among them, the consistency relationship or linkage relationship is used to characterize that the fire-fighting equipment object is related to the current fire alarm response task, and the irrelevance relationship is used to characterize that the fire-fighting equipment object is not related to the current fire alarm response task, and the relationship is one of the bases for determining the influence level.

[0030] Secondly, the present invention also provides a building fire protection facility leakage current monitoring system, comprising:

[0031] The association modeling module is used to pre-establish or update the functional association model between power supply circuits, fire equipment, fire zones, fire linkage objects and equipment task priorities based on the power supply topology, equipment wiring, fire zones and fire linkage configuration relationships of building fire protection facilities.

[0032] The data acquisition module is used to acquire electrical anomaly monitoring data, real-time equipment operation feedback data, and fire linkage status data in real time. The electrical anomaly monitoring data includes at least the leakage anomaly signal of the target power supply circuit.

[0033] The task status identification module is used to determine the fire equipment object, fire zone, associated fire linkage object and current task status information corresponding to the target power supply circuit based on the functional association model when the leakage abnormal signal is detected.

[0034] The functional impact assessment module is used to determine the impact level of the leakage abnormal signal based on whether the fire equipment object participates in the current fire linkage task, the equipment task priority, the relationship between the fire zone to which it belongs and the current fire alarm zone, and the real-time operation feedback data of the equipment.

[0035] The response output module is used to output corresponding alarm prompts or monitoring and control results according to the impact level. For impact situations related to the current fire alarm response task, the monitoring and control results include ensuring continuous power supply to the corresponding fire-fighting equipment.

[0036] The recording module is used to record the leakage current abnormal signal, the impact level, and the output results.

[0037] Thirdly, the present invention also provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the processor executes the computer program, it implements the building fire protection facility leakage current monitoring method as described in the first aspect.

[0038] Fourthly, the present invention also provides a non-transitory computer-readable storage medium having a computer program stored thereon, wherein when the computer program is executed by a processor, it implements the building fire protection facility leakage current monitoring method as described in the first aspect.

[0039] This invention establishes a functional association model between power supply circuits, fire-fighting equipment, fire zones, fire-fighting linkage objects, and task priorities. Upon detecting a leakage current anomaly, it combines the current fire-fighting linkage task, fire alarm zone relationship, and real-time equipment operating status to determine the impact level and output differentiated alarm prompts or monitoring and control results accordingly. For equipment related to the current fire alarm handling task, priority can be given to ensuring continuous power supply in abnormal situations, thereby improving the matching of leakage current anomaly handling with fire-fighting business scenarios, enhancing the accuracy of alarm classification, the reliability of power supply guarantee, and the system security during fire alarm handling.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0047] In the description of this invention, building fire protection facilities may include fire pumps, smoke exhaust fans, pressurized air supply fans, fire elevators, fire shutters, automatic fire alarm equipment, emergency lighting equipment, fire broadcast equipment, and other fire-related linkage equipment. The current fire alarm zone may be determined by the automatic fire alarm system, fire linkage controller, or fire control host based on the current fire alarm signal. The power supply circuit may be a main circuit, branch circuit, or terminal distribution circuit supplying power to the building fire protection facilities. The leakage current abnormality signal may be collected by a residual current monitoring device, insulation monitoring device, or integrated electrical fire monitoring device.

[0048] See Figure 1 , Figure 1 This is a flowchart illustrating a method for monitoring leakage current in building fire protection facilities according to an embodiment of the present invention. The method for monitoring leakage current in building fire protection facilities according to this embodiment can operate in a hardware environment including a monitoring terminal, a fire control host, a linkage data interface, and an alarm output terminal. The method includes the following steps:

[0049] Step 10: Based on the power supply topology, equipment wiring, fire zones, and fire linkage configuration of the building's fire protection facilities, establish or update the functional association model between power supply circuits, fire protection equipment, fire zones, fire linkage objects, and equipment task priorities in advance.

[0050] This step is the correlation modeling stage of the building fire protection facility leakage current monitoring method, and it is also one of the basic steps to realize the subsequent fire protection function impact assessment. By establishing the correlation between power supply circuit, fire protection equipment, fire zone, fire linkage object and equipment task priority in advance, the fire protection equipment object corresponding to the target power supply circuit can be quickly located after the leakage current abnormal signal is detected, and the fire zone to which the fire protection equipment object belongs, the associated fire linkage object and the equipment task priority can be further determined.

[0051] The functional association model includes: the mapping relationship between power supply circuits and fire-fighting equipment, the mapping relationship between fire-fighting equipment and fire zones, the mapping relationship between fire-fighting equipment and fire linkage objects, and the mapping relationship between fire-fighting equipment and equipment task priorities. Specifically, steps 101-104 are described below.

[0052] By executing step 10, the power supply and distribution relationship and the fire protection business relationship in the building fire protection facilities can be established in advance, providing a unified data foundation for the subsequent identification of leakage abnormal objects and the determination of the impact level. This avoids the need for isolated judgments based on a single electrical parameter and improves the adaptability of leakage monitoring results to fire protection business scenarios.

[0053] Step 20: Real-time acquisition of electrical anomaly monitoring data, real-time equipment operation feedback data, and fire alarm linkage status data. The electrical anomaly monitoring data shall include at least the leakage anomaly signal of the target power supply circuit.

[0054] This step is the data acquisition stage of the building fire protection facility leakage monitoring method. Its main function is to provide real-time data support for subsequent anomaly identification and impact level determination.

[0055] The electrical anomaly monitoring data includes, in addition to leakage current anomaly signals, at least one of insulation anomaly signals and circuit fault status signals; the real-time equipment operation feedback data is used to characterize the current operating status of the fire protection equipment; the fire linkage status data is used to characterize whether there is a fire alarm in the current fire protection system, the zone to which the fire alarm belongs, whether the linkage task has been initiated, the linkage objects that have been initiated, and the current linkage stage. Specifically, steps 201-204 are described below.

[0056] By executing step 20, electrical side abnormal data, equipment side operation data, and linkage side status data can be obtained simultaneously, thus providing a data foundation for subsequent correlation analysis between leakage current abnormalities and the current fire-fighting task scenario, avoiding misjudgment or improper handling caused by judging based solely on the single dimension of leakage current value.

[0057] Step 30: When the leakage current abnormal signal is detected, the fire equipment object, fire zone, associated fire linkage object and current task status information corresponding to the target power supply circuit are determined based on the functional association model.

[0058] This step is the leakage current abnormality object identification stage. Its main function is to convert the electrical abnormality information on the target power supply circuit into object information with fire protection business semantics.

[0059] Specifically, after detecting the leakage current abnormal signal, based on the functional association model established or updated in step 10, the fire equipment object corresponding to the target power supply circuit, the fire zone to which it belongs, and the associated fire linkage object are determined. Combined with the real-time operation feedback data of the equipment and the fire linkage status data obtained in step 20, the current task status information is determined.

[0060] The current task status information includes: the current operating status of the corresponding fire-fighting equipment, whether it participates in the current fire-fighting linkage task, the current fire-fighting linkage stage, whether it is in an already activated state, and whether it belongs to a task to be activated. Specifically, steps 301-304 are described below.

[0061] By executing step 30, the "circuit anomaly" can be further analyzed into "which fire-fighting equipment, which zone, and what task status the anomaly is in," thus providing a clear and complete object basis for subsequent impact level determination, and enabling the leakage current monitoring results to truly reflect its actual impact on the current fire-fighting task.

[0062] Step 40: Determine the impact level of the leakage current abnormal signal based on whether the fire-fighting equipment is involved in the current fire linkage task, the equipment task priority, the relationship between the fire zone to which it belongs and the current fire alarm zone, and the real-time operation feedback data of the equipment.

[0063] This step is the functional impact assessment of the leakage current monitoring method for building fire protection facilities, and it is also one of the core steps of this invention.

[0064] Its main function is to make a progressive judgment on the leakage current abnormal signal by combining whether the target fire-fighting equipment is involved in the current fire linkage task, the equipment task priority, the relationship between the fire zone to which it belongs and the current fire alarm zone, and the real-time operation feedback data of the equipment.

[0065] The impact levels, from highest to lowest, include critical function risk level, task execution impact level, standby capability impact level, and general electrical anomaly level. The determination of the critical function risk level takes precedence over the task execution impact level, standby capability impact level, and general electrical anomaly level. The relationship between the fire compartment to which the fire equipment belongs and the current fire alarm compartment includes consistency, linkage, and irrelevance. Specifically, steps 401-404 are described below.

[0066] By executing step 40, the leakage current anomaly can be further transformed from "electrical risk" to "fire protection function impact risk", realizing the hierarchical identification of the relevance of the leakage current anomaly to the current fire alarm handling task, thereby improving the business adaptability of the impact level determination, and providing a basis for subsequent differentiated output of alarm prompts or monitoring and control results.

[0067] Step 50: Output corresponding alarm prompts or monitoring and control results according to the impact level. For impact situations related to the current fire alarm response task, the monitoring and control results include ensuring continuous power supply to the corresponding fire-fighting equipment.

[0068] This step is the response output stage of the building fire protection facility leakage current monitoring method. Its main function is to output a matching alarm prompt or monitoring control result based on the impact level determined in step 40.

[0069] Furthermore, the alarm prompts or monitoring and control results include at least one of the following: general abnormality records, maintenance prompts, priority maintenance prompts, manual intervention prompts, high-level early warnings, enhanced monitoring with faults, backup equipment call control commands or call prompts, and backup power supply path call control commands or call prompts.

[0070] Optionally, when the impact level is a general electrical anomaly level, a general anomaly record and maintenance prompt can be output; when the impact level is a standby capability impact level, a priority maintenance prompt can be output; when the impact level is a task execution impact level, a high-level early warning and enhanced monitoring with faults can be output; when the impact level is a critical function risk level, at least one of the following can be further output: a manual intervention prompt, a backup equipment call control command or call prompt, or a backup power supply path call control command or call prompt.

[0071] Furthermore, when the impact level is the task execution impact level or the critical function risk level, the fire-fighting equipment corresponding to the target power supply circuit is controlled to enter the enhanced monitoring mode with faults. In the enhanced monitoring mode with faults, without cutting off the power supply to the target power supply circuit, the frequency of abnormal monitoring of the target power supply circuit is increased, and the early warning response cycle and / or monitoring data upload cycle is shortened. Specifically, steps 501-503 are described as follows.

[0072] By executing step 50, differentiated alarm prompts or monitoring and control results can be output according to different impact levels. Especially in situations related to the current fire alarm response task, by ensuring continuous power supply to the corresponding fire-fighting equipment and implementing enhanced monitoring with faults, the interruption of critical fire-fighting functions caused by simply cutting off the power supply can be avoided, thereby taking into account both electrical risk warnings and the continuity of fire-fighting tasks.

[0073] Step 60: Record the leakage current abnormal signal, its impact level, and the output result.

[0074] This step is the data recording and traceability stage. Its main purpose is to completely record the identification of leakage anomalies, the determination of the impact level, and the output response results, so as to facilitate subsequent fault tracing, operation and maintenance analysis, equipment health assessment, and monitoring strategy optimization. Specifically, steps 601-603 are described below.

[0075] By executing step 60, a complete anomaly monitoring file can be generated, providing data support for subsequent historical queries, trend analysis, operation and maintenance decisions, and fire risk management.

[0076] The leakage current monitoring method for building fire protection facilities provided in this invention establishes a functional association model in advance. After detecting an abnormal leakage current signal, it identifies the corresponding fire protection equipment, the fire zone to which it belongs, the associated fire linkage objects, and the current task status information. It then combines the equipment task priority, zone relationship, and real-time operation feedback data to progressively determine the impact level of the leakage current anomaly. Based on different impact levels, it outputs differentiated alarm prompts or monitoring and control results. This solves the problem in the prior art that the leakage current anomaly is uniformly processed based on a single electrical parameter, making it difficult to reflect its actual impact on the current fire protection task. It has the advantages of improving the adaptability of alarm classification services, enhancing the continuity of fire protection functions, and reducing unreasonable handling.

[0077] In one embodiment, steps 101-104 are described as follows:

[0078] Step 101: Obtain the power supply topology data, equipment wiring data, fire zone data, and fire linkage configuration data of the building's fire protection facilities.

[0079] This step is the data preparation stage for building the functional association model. Its main purpose is to obtain the basic data sources needed to establish the mapping relationship between power supply circuits, fire protection equipment, fire zones, and fire linkage objects. By uniformly collecting and organizing the power supply structure, equipment wiring relationships, zone division information, and fire linkage configuration relationships in the building's fire protection facilities, the original data foundation can be provided for the subsequent construction of the functional association model.

[0080] Optionally, the power supply topology data is used to characterize the power supply connection relationship between the power distribution source, power supply circuit, branch line and end load; the equipment wiring data is used to characterize the actual wiring correspondence between each fire-fighting equipment object and the target power supply circuit; the fire zone data is used to characterize the fire zone to which the fire-fighting equipment object belongs or serves; and the fire linkage configuration data is used to characterize the preset linkage relationship between each fire-fighting equipment object and the fire linkage object.

[0081] Furthermore, the data may come from at least one of the following: building electromechanical as-built drawings, fire protection system location list, power distribution system list, fire linkage programming table, equipment asset ledger, and on-site verification results.

[0082] By executing step 101, structured data support can be provided for the subsequent establishment of a complete and accurate functional association model, thereby ensuring that the subsequent leakage current anomaly identification results can correspond to specific fire protection equipment objects and their business scenarios.

[0083] Step 102: Based on the power supply topology data, equipment wiring data, fire zone data, and fire linkage configuration data, establish the mapping relationship between power supply circuits and fire equipment, fire equipment and fire zones, and fire equipment and fire linkage objects.

[0084] This step is the functional association generation stage. Its main function is to associate and integrate the various basic data obtained in step 101 to form a multi-dimensional mapping relationship that can be used for subsequent rapid retrieval and judgment. Through this step, it is possible to realize the hierarchical association from the target power supply circuit to the fire equipment object, from the fire equipment object to the fire zone, and from the fire equipment object to the fire linkage object.

[0085] Optionally, when establishing the mapping relationship between power supply circuits and fire-fighting equipment, at least one fire-fighting equipment object corresponding to each target power supply circuit can be determined based on the equipment wiring data; when establishing the mapping relationship between fire-fighting equipment and fire zones, the fire zone to which the fire-fighting equipment object belongs or serves can be determined based on the fire zone data; when establishing the mapping relationship between fire-fighting equipment and fire-fighting linkage objects, the linkage objects and linkage task relationships of the fire-fighting equipment object in the preset fire alarm scenario can be determined based on the fire-fighting linkage configuration data.

[0086] Furthermore, when a target power supply circuit corresponds to multiple fire-fighting equipment objects, independent entries can be established for each of the multiple fire-fighting equipment objects in the functional association model, so that task status identification and impact level determination can be performed separately for each object in the future.

[0087] By executing step 102, a basic link can be formed from electrical circuit information to fire protection business information, so that subsequent leakage current monitoring will no longer be limited to the circuit level, but can be further mapped to the fire protection function level.

[0088] Step 103: Based on the functional importance of the fire-fighting equipment in the fire alarm response task, set the equipment task priority for the corresponding fire-fighting equipment.

[0089] This step is the task priority setting stage. Its main function is to pre-classify the importance of different fire-fighting equipment objects in the fire alarm handling process, thereby providing a priority basis for the progressive determination of the subsequent impact level.

[0090] Optionally, the task priority of the equipment can be set according to the role of the fire-fighting equipment in scenarios such as fire-fighting water supply, smoke prevention and exhaust, pressurized air supply, fire alarm linkage control, personnel evacuation guidance, emergency broadcasting, and fire elevator operation.

[0091] For fire-fighting equipment that plays a critical role in the current fire alarm response, its equipment task priority can be set to high priority; for fire-fighting equipment that plays an auxiliary role or a subsequent support role, its equipment task priority can be set to medium priority or low priority.

[0092] Furthermore, the device task priority can also be calibrated in conjunction with the impact of device failure on the continuity of the current fire alarm response, the safety of personnel evacuation, and the expansion of secondary risks.

[0093] By performing step 103, it is possible to distinguish between critical and non-critical equipment in the subsequent impact assessment of leakage current anomalies, thereby improving the pertinence and business rationality of the impact level determination.

[0094] Step 104: Write the mapping relationship and device task priority into the functional association model, and update the functional association model when the power supply topology, device wiring, fire zone or fire linkage configuration relationship changes.

[0095] This step is the generation and maintenance of the functional association model. Its main function is to write the various mapping relationships formed in step 102 and the equipment task priorities set in step 103 into a unified functional association model, and to update the functional association model synchronously when the configuration of building fire protection facilities changes, so as to ensure that the model content is consistent with the actual site.

[0096] Optionally, when fire-fighting equipment is added, removed, or replaced in the building, or when the power supply circuit is adjusted, fire zones are re-divided, or fire linkage configuration is changed, the data acquisition and mapping establishment process corresponding to steps 101 to 103 can be called again to update the functional association model.

[0097] Furthermore, the functional association model can be periodically verified, and the verification content includes at least one of the following: consistency of device object identification, consistency of loop number, consistency of partition affiliation, and consistency of linkage relationship.

[0098] By executing step 104, the data used for subsequent leakage current anomaly identification and impact level determination can be kept valid, thereby improving the applicability and reliability of the method of the present invention in actual engineering environments.

[0099] In one embodiment, steps 201-204 are described as follows:

[0100] Step 201: Collect electrical anomaly monitoring data of the target power supply circuit in real time.

[0101] This step is the electrical side abnormal data collection stage. Its main function is to continuously monitor the power supply circuits related to the building's fire protection facilities in order to promptly detect abnormal electrical conditions in the target power supply circuits.

[0102] Optionally, the electrical anomaly monitoring data includes at least leakage current anomaly signals, and may also include at least one of insulation anomaly signals and circuit fault status signals.

[0103] The leakage current abnormality signal can be used to characterize the presence of residual current abnormality or leakage risk in the target power supply circuit; the insulation abnormality signal can be used to characterize the degradation of circuit insulation performance; and the circuit fault status signal can be used to characterize the circuit open circuit, short circuit, grounding abnormality, or monitoring device failure.

[0104] Furthermore, the leakage current abnormal signal may include at least one of the following: leakage current value, leakage current change trend, abnormal duration, and threshold over-limit state.

[0105] By executing step 201, abnormal changes in the target power supply circuit can be detected in a timely manner, providing triggering conditions for subsequent object identification and impact assessment.

[0106] Step 202: Collect real-time operation feedback data of the fire protection equipment.

[0107] This step is the equipment-side status acquisition stage. Its main function is to obtain the actual operating status of the fire protection equipment at the current moment, so as to determine whether the leakage abnormality has affected the equipment's ability to perform the current task or its subsequent deployment.

[0108] Optionally, the real-time operation feedback data of the equipment includes at least one of the following: operating status, standby status, fault status, engaged status, disengaged status, or locked status. For fire-fighting equipment that is already in operation, the real-time operation feedback data can also be used to characterize whether its current action has been completed, whether the feedback is normal, and whether the function is continuously maintained.

[0109] Furthermore, for different types of fire protection equipment such as fans, water pumps, elevators, and roller shutters, the real-time operation feedback data of the equipment may also include at least one of start / stop feedback, operation feedback, fault feedback, arrival feedback, location feedback, and linkage response feedback.

[0110] By executing step 202, direct equipment status information can be provided for subsequent determinations of whether the current task is affected or whether subsequent input capacity is affected, thereby avoiding mechanical judgment based solely on circuit abnormalities.

[0111] Step 203: Collect fire alarm linkage status data in real time.

[0112] This step is the linkage side status acquisition stage. Its main function is to obtain the fire alarm linkage scenario information of the current building fire protection system, so as to determine whether the fire equipment object is related to the current fire alarm handling task.

[0113] Optionally, the fire alarm linkage status data includes at least one of the following: whether a fire alarm exists, the zone to which the fire alarm belongs, whether the linkage task has been initiated, the linkage objects that have been initiated, and the current linkage stage.

[0114] The current linkage stage may include at least one of the following: initial alarm stage, linkage start-up stage, equipment execution stage, continuous handling stage, or subsequent pending deployment stage.

[0115] Furthermore, the fire alarm linkage status data may also include at least one of the following: the current fire alarm level, whether there is a multi-zone fire alarm, whether there is cross-zone linkage, and the current linkage strategy version.

[0116] By executing step 203, a linkage scenario foundation can be provided for subsequent identification of the current fire alarm zone, determination of whether fire-fighting equipment objects participate in the current fire linkage task, and determination of the current task status information.

[0117] Step 204: Transmit the electrical anomaly monitoring data, real-time equipment operation feedback data, and fire alarm linkage status data to the subsequent identification and evaluation process.

[0118] This step is a multi-source data aggregation stage. Its main function is to uniformly transmit the data from different sources obtained in steps 201 to 203 to the subsequent object identification and impact level assessment process, so as to realize the joint analysis of data across the electrical side, equipment side and linkage side.

[0119] Optionally, the electrical anomaly monitoring data, real-time equipment operation feedback data, and fire alarm linkage status data can be matched and aligned using a unified time identifier, a unified equipment identifier, or a unified circuit identifier to ensure data consistency in subsequent analysis processes.

[0120] Furthermore, the collected data can be processed by denoising, missing value compensation, state standardization, and outlier removal before transmission.

[0121] By executing step 204, the synchronous association of multi-source data can be achieved, providing a complete data support link for subsequent assessment of the impact of leakage current anomalies.

[0122] In one embodiment, steps 301-304 are described as follows:

[0123] Step 301: Determine the corresponding fire-fighting equipment object from the functional association model based on the target power supply circuit.

[0124] This step is the initial location of abnormal objects. Its main function is to first determine the fire-fighting equipment that is actually powered by the circuit after detecting a leakage abnormality signal in the target power supply circuit.

[0125] Optionally, when the target power supply circuit corresponds to only one fire-fighting equipment object, the fire-fighting equipment object is directly determined as the subsequent evaluation object; when the target power supply circuit corresponds to multiple fire-fighting equipment objects, all multiple fire-fighting equipment objects can be used as subsequent evaluation objects, and subsequent zoning identification, task status identification and impact level determination can be performed respectively.

[0126] Furthermore, when the target power supply circuit corresponds to multiple fire-fighting equipment objects and some of these fire-fighting equipment objects are not currently in service, the currently valid objects can be selected first to enter the subsequent process.

[0127] By executing step 301, the mapping and identification from the target power supply circuit to the fire protection equipment object can be realized, so that the leakage current abnormality is transformed from "circuit-level abnormality" to "equipment-level abnormal object".

[0128] Step 302: Based on the fire equipment object, determine the fire zone and associated fire linkage object from the functional association model.

[0129] This step is the business attribute identification stage. Its main function is to further identify the fire zone to which the fire equipment belongs or serves, as well as its associated objects and linkage relationships in the fire linkage system, based on the already identified fire equipment objects.

[0130] Optionally, the fire zone may be the zone where the fire-fighting equipment is installed, or it may be the target zone served or controlled by the fire-fighting equipment; the associated fire linkage object may include alarm objects, control objects, execution objects, or feedback objects that have a preset linkage relationship with the fire-fighting equipment.

[0131] Furthermore, when a fire protection equipment object has cross-zone service capabilities, the functional association model can record the main service zone and associated service zones corresponding to the fire protection equipment object.

[0132] By executing step 302, we can further provide a basis for determining whether the fire-fighting equipment is related to the current fire alarm response task, including the zoning and linkage relationships.

[0133] Step 303: Combine the real-time operation feedback data of the equipment and the fire linkage status data to determine the current task status information of the fire equipment object.

[0134] This step is the task status identification stage. Its main function is to identify the task participation and execution status of fire-fighting equipment objects in the current fire alarm scenario by combining the current feedback status of the equipment and the status of the fire-fighting linkage scenario.

[0135] Optionally, the current task status information includes: the current operating status of the corresponding fire-fighting equipment, whether it participates in the current fire-fighting linkage task, the current fire-fighting linkage stage, whether it is in an activated state, and whether it belongs to a task object to be activated. If the fire-fighting equipment object has been linked and is in an operating state, it can be determined that it participates in the current fire-fighting linkage task and is in an activated state; if the fire-fighting equipment object is not currently activated but needs to be activated in a subsequent stage according to the linkage configuration, it can be determined that it belongs to a task object to be activated.

[0136] Furthermore, when the fire alarm status data shows that the current fire alarm zone is still in the initial alarm stage, and the linkage conditions corresponding to the fire equipment object have not yet been met, the fire equipment object can be marked as not participating in the current fire alarm linkage task but having the potential for subsequent deployment.

[0137] By executing step 303, it is possible to accurately identify whether the fire-fighting equipment is currently performing a task, whether it has been put into operation, or whether it is to be put into operation later, thereby providing key status basis for the determination of the impact level.

[0138] Step 304: Output the fire equipment object, its fire zone, associated fire linkage object, and current task status information to the impact level determination process.

[0139] This step is the identification result output stage. Its main function is to unify the identification results formed in steps 301 to 303 as input information for subsequent impact level determination.

[0140] Optionally, when the target power supply circuit corresponds to multiple fire-fighting equipment objects, the corresponding fire zone, associated fire linkage objects and current task status information can be output for each of the multiple fire-fighting equipment objects, so as to conduct subsequent evaluations by object or comprehensive evaluations.

[0141] Furthermore, loop source identifiers can be added to the identification results of multiple fire-fighting equipment objects to facilitate subsequent switching between analysis at the same loop dimension and single equipment object dimension.

[0142] By executing step 304, subsequent impact level determination can be based on the completed object identification, partition identification, and task status identification, thereby improving the accuracy of functional impact assessment and business consistency.

[0143] In one embodiment, steps 401-404 are described as follows:

[0144] Step 401: Determine whether the fire-fighting equipment is a critical mission device and whether it is related to the current fire alarm response mission.

[0145] This step is a preliminary identification process for determining the impact level. Its main function is to first identify the importance of the fire-fighting equipment in the current scenario and its relevance to the current fire alarm response task, thus providing a prerequisite for subsequent progressive determination.

[0146] Optionally, fire-fighting equipment with a task priority higher than a preset priority threshold is designated as critical task equipment. Further, if the fire zone to which the fire-fighting equipment belongs and the current fire alarm zone are consistent or linked, then the fire-fighting equipment is determined to be related to the current fire alarm response task; if they are unrelated, then the fire-fighting equipment is determined to be unrelated to the current fire alarm response task.

[0147] Furthermore, the linkage relationship can indicate that after the current fire alarm zone is triggered, the fire-fighting equipment object should participate in the handling tasks of adjacent zones, same-floor zones, upper and lower-floor zones, or other linkage-related areas according to the linkage configuration.

[0148] By executing step 401, it is possible to first distinguish between critical and non-critical equipment, and between relevant and irrelevant equipment, thereby avoiding a lack of scenario basis for subsequent impact level determination.

[0149] Step 402: When the fire-fighting equipment is a critical mission device, related to the current fire alarm response mission, and the leakage current abnormal signal may cause the corresponding fire-fighting function to be interrupted, it is determined to be a critical function risk level.

[0150] This step is the highest priority impact assessment stage. Its main function is to prioritize the identification of leakage abnormalities that pose a direct threat to the critical fire protection functions in the current fire alarm response process.

[0151] Optionally, the leakage current abnormal signal may cause the corresponding fire protection function to be interrupted, and the judgment can be made based on at least one of the abnormal duration, abnormal intensity, real-time operation feedback status of the equipment, and historical fault modes of the target power supply circuit.

[0152] For example, if a leakage current anomaly persists in the target power supply circuit and the corresponding equipment has been put into operation to perform critical tasks, it can be determined that the leakage current anomaly may cause the interruption of critical fire protection functions.

[0153] Furthermore, when the fire-fighting equipment exhibits at least one of the following conditions: unstable operation, repeated start-stop, inability to maintain linkage action, abnormal power supply fluctuations, or risk of operation of the protection device, it can also be determined that the leakage current abnormal signal may cause the corresponding fire-fighting function to be interrupted.

[0154] By performing step 402, high-risk scenarios that most require continuous power supply and enhanced monitoring measures can be identified first, thereby ensuring the continuity of critical fire protection functions.

[0155] Step 403: When the fire-fighting equipment does not meet the criteria for determining the risk level of critical functions, participates in the current fire-fighting linkage task, and the leakage current abnormal signal affects the execution of the current task, it is determined to be the task execution impact level.

[0156] This step is the current task impact assessment stage. Its main function is to identify leakage current abnormalities that have already had a real impact on the execution of the current linked task, but have not yet reached the critical function risk level.

[0157] Optionally, "affecting the execution of the current task" can be characterized as at least one of the following: the equipment is in operation but the operating status is abnormal, the linkage action is not completed, the action feedback is abnormal, the operation continuity is reduced, or the execution result is inconsistent with the preset linkage requirements.

[0158] Furthermore, when fire-fighting equipment has participated in the current fire-fighting linkage task but has not yet posed a risk of complete interruption of critical functions, but has experienced delayed action, delayed feedback, linkage failure retry, or performance degradation, it can also be determined as the task execution impact level.

[0159] By executing step 403, leakage current abnormalities that have directly interfered with the current linkage task can be identified, so as to output high-level early warning and enhanced monitoring results with faults in a timely manner.

[0160] Step 404: When the fire-fighting equipment does not meet the criteria for determining the risk level of critical functions and the impact level of task execution, and does not participate in the current fire-fighting linkage task but the leakage current abnormal signal affects the subsequent deployment capability, it is determined to be at the standby capability impact level; otherwise, it is determined to be at the general electrical abnormality level.

[0161] This step is for determining the subsequent operational capability and general anomaly. Its main purpose is to determine whether the leakage anomaly will affect the subsequent operation of the fire protection equipment after ruling out higher-level impacts. If it does not affect the subsequent operational capability, it is classified as a general electrical anomaly.

[0162] Optionally, the "impact on subsequent deployment capability" can be characterized as the fact that although the equipment is not currently in operation, there is an abnormality in the corresponding power supply circuit, which may cause the equipment to fail to start normally, fail to maintain normal operation, or have unstable function after being put into operation during the subsequent linkage phase.

[0163] Furthermore, when a leakage current abnormality signal only indicates the existence of a general electrical hazard, but has not yet directly affected the current task execution and subsequent investment capacity, it can be determined as a general electrical abnormality level.

[0164] By executing step 404, it is possible to further distinguish between abnormal situations that affect standby capability and general electrical abnormal situations, making the impact level determination results more detailed and more in line with actual fire protection business needs.

[0165] In one embodiment, steps 501-503 are described as follows:

[0166] Step 501: Maintain continuous power supply to the corresponding fire-fighting equipment without cutting off the power supply to the target power supply circuit.

[0167] This step is the continuous power supply guarantee link. Its main function is to prioritize ensuring the continuity of the corresponding fire-fighting equipment functions when the impact level is the task execution impact level or the critical function risk level, under the conditions related to the current fire alarm response task.

[0168] It should be noted that maintaining the continuous power supply to the corresponding fire-fighting equipment means prioritizing the maintenance of fire-fighting function continuity in the current fire alarm response scenario, and controlling risks by combining enhanced monitoring, alarm prompts and manual intervention, rather than excluding the possibility of taking further action in the event of a serious malfunction or manual confirmation.

[0169] Furthermore, in embodiments with backup equipment or backup power supply paths, backup equipment call control commands or backup power supply path call control commands can be pre-generated while maintaining the continuous power supply operation of the current fire-fighting equipment, for manual confirmation or execution when conditions are met.

[0170] By performing step 501, it is possible to avoid simply cutting off power to fire-fighting equipment related to the current fire alarm response task, thereby reducing the risk of interruption of critical fire-fighting functions.

[0171] Step 502: Increase the frequency of anomaly monitoring for the target power supply circuit.

[0172] This step is a high-frequency monitoring component in enhanced fault monitoring. Its main function is to strengthen the real-time tracking of abnormal changes in risk circuits while maintaining continuous power supply.

[0173] Optionally, at least one of the following can be increased: leakage current anomaly sampling frequency, insulation status refresh frequency, fault status monitoring frequency, or related equipment feedback status polling frequency of the target power supply circuit, in order to enhance the monitoring capability of abnormal trend changes.

[0174] Furthermore, for target power supply circuits corresponding to the risk level of critical functions, the monitoring frequency can be increased to a preset multiple higher than that of normal operation, so as to detect abnormal deterioration trends more promptly.

[0175] By performing step 502, it is possible to timely grasp the change of the risk status of the target power supply circuit without cutting off the power supply, providing more timely data support for subsequent manual intervention or standby path invocation.

[0176] Step 503, shorten the warning response cycle and / or the monitoring data upload cycle.

[0177] This step is to strengthen the fast response link in monitoring, and its main role is to improve the transmission efficiency of abnormal information and the warning response speed in high-risk scenarios.

[0178] Optionally, the response cycle from abnormal monitoring to warning output can be shortened, or the upload cycle of monitoring data to the fire control host, the fire control room platform or the remote operation and maintenance platform can be shortened, so that relevant personnel can more quickly learn about the risk changes.

[0179] Furthermore, when the impact level is the critical function risk level, high-priority warnings can be pushed to both the warning output terminal and the fire control host at the same time to improve the disposal efficiency.

[0180] By performing step 503, it is possible to further improve the warning timeliness in high-risk leakage abnormal scenarios, providing support for the generation and execution of manual intervention prompts, standby equipment call control instructions or standby power supply path call control instructions.

[0181] In one embodiment, the descriptions of steps 601 - 603 are as follows:

[0182] Step 601, record the basic electrical information corresponding to the leakage abnormal signal.

[0183] This step is the basic abnormal information recording link, and its main role is to retain the original electrical information on the electrical side of this leakage abnormality for subsequent fault tracing and historical analysis.

[0184] Optionally, the basic electrical information includes at least one of the target power supply circuit identifier, abnormal type, abnormal occurrence time, abnormal intensity, and abnormal duration; when there are insulation abnormal signals or loop fault status signals at the same time, they can also be recorded together. Furthermore, the basic electrical information can also include at least one of the monitoring device identifier, sampling timestamp, abnormal threshold information, and abnormal change trend information.

[0185] By performing step 601, it is possible to provide basic data for subsequent review of the abnormal occurrence process, analysis of abnormal trends, and identification of the loop health status.

[0186] Step 602, record the fire protection service information corresponding to the leakage abnormality.

[0187] This step is the business semantic information recording stage. Its main function is to retain the fire protection business object information and scene information corresponding to this leakage anomaly, thereby forming a recording result that includes not only electrical anomalies but also fire protection business meanings.

[0188] Optionally, the fire protection business information includes at least one of the following: fire equipment object identifier, fire zone to which it belongs, current fire alarm zone, current task status information, and impact level.

[0189] Furthermore, the fire protection business information may also include at least one of the following: associated fire protection linkage objects, equipment task priority, and current linkage stage.

[0190] By executing step 602, the electrical anomaly record can be linked with the fire protection business scenario record, providing a basis for subsequent operation and maintenance personnel to analyze which fire protection equipment was affected by the anomaly, in which scenario it was located, and what risk level it corresponds to.

[0191] Step 603: Record alarm prompts and monitoring and control results.

[0192] This step is the response result recording stage. Its main purpose is to record the alarm prompts and monitoring and control measures triggered by this leakage anomaly, so as to evaluate the implementation of the strategy and the effectiveness of the handling in the future.

[0193] Optionally, the monitoring and control results include at least one of the following: whether to activate the enhanced monitoring mode with faults, whether to output the continuous power supply guarantee result, whether to output the backup equipment call control command or call prompt, whether to output the backup power supply path call control command or call prompt, and the abnormality clearance time.

[0194] Furthermore, the recorded content may also include at least one of the following: alarm receiving object, alarm confirmation time, manual intervention time, and handling completion status.

[0195] By executing step 603, a complete record chain can be formed from the occurrence of an anomaly, object identification, impact determination to response output, providing support for subsequent historical queries, strategy optimization and operation and maintenance management.

The relationship between the fire zone to which the fire-fighting equipment belongs and the current fire alarm zone includes consistency, linkage, and irrelevance. Among them, the consistency relationship means that the fire zone to which the fire equipment belongs is the same as the current fire alarm zone; the linkage relationship means that although the fire zone to which the fire equipment belongs is different from the current fire alarm zone, there is a preset fire linkage configuration relationship with the current fire alarm zone; and the irrelevant relationship means that there is no preset fire linkage configuration relationship between the fire zone to which the fire equipment belongs and the current fire alarm zone. Among them, the consistency relationship or linkage relationship is used to characterize that the fire-fighting equipment object is related to the current fire alarm response task, and the irrelevance relationship is used to characterize that the fire-fighting equipment object is not related to the current fire alarm response task, and the relationship is one of the bases for determining the influence level; The response output module is used to output corresponding alarm prompts or monitoring and control results according to the impact level. For impact situations related to the current fire alarm response task, the monitoring and control results include ensuring continuous power supply to the corresponding fire-fighting equipment. The alarm prompts or monitoring and control results include at least one of the following: manual intervention prompts, backup equipment call control commands or prompts, and backup power supply path call control commands or prompts. When the impact level is the task execution impact level or the critical function risk level, the fire-fighting equipment corresponding to the target power supply circuit is controlled to enter the fault-enhanced monitoring mode. In the enhanced fault monitoring mode, without cutting off the power supply to the target power supply circuit, the frequency of abnormal monitoring of the target power supply circuit is increased, and the early warning response cycle and / or monitoring data upload cycle are shortened. The recording module is used to record the leakage current abnormal signal, the impact level, and the output results.
