Description

Technical Field

[0001] The present invention relates to the field of fire protection systems, and in particular to a fire protection linkage control system and a fire protection equipment fault locating method. Background Art

[0002] Existing fire protection systems suffer from widespread issues such as insufficient fire response linkage accuracy, inefficient fault location, and a high risk of misoperation. Traditional systems employ a crude zoning of fire protection facilities, often managing them on a building-by-building or large-area basis. This makes it difficult to implement precise linkage control based on the specific location and spread of a fire. This often results in excessive linkage scope, wasting resources, or insufficient linkage, delaying firefighting efforts.

[0003] At the same time, firefighting equipment fault diagnosis often relies on single signal feedback, lacking comprehensive analysis of the equipment's functional attributes, location information, and historical status, making it prone to misjudgments or missed detections. For example, if a detector falsely alarms, the system may mistakenly initiate a large-scale linkage, or fail to identify the fault in a timely manner due to the equipment's lack of response, resulting in the equipment not being able to operate normally at a critical moment.

[0004] Furthermore, the system's verification mechanism for device status signals was imperfect, lacking rigorous verification of the signals' compatibility with the actual device deployment and control logic. This could easily lead to erroneous linkage operations due to signal confusion, exacerbating the risk of fire emergency response. For example, if a device signal in a non-fire zone were mistakenly used for linkage control, it could cause firefighting equipment in unrelated areas to activate, hindering evacuation and firefighting operations.

[0005] Furthermore, fire parameter analysis relies on a single dimension, relying solely on fire data from a single area to determine the threat level. This makes it difficult to accurately assess fire spread trends, leading to irrational linkage scope decisions. Furthermore, the fault diagnosis model is fixed, making it impossible to dynamically adjust the detection depth based on the fire load. This makes it difficult to quickly locate potential faults during periods of high fire activity or high equipment load, impacting the system's emergency response capabilities. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a fire linkage control system and a fire equipment fault locating method to solve the problems raised in the background technology.

[0015] Furthermore, the feedback data includes a first fire condition parameter value and a second fire condition parameter value.

[0016] The zone control unit determines the fire threat level by comparing the first fire parameter value with the second fire parameter value.

[0017] The master controller determines the linkage range based on the fire threat level.

[0018] The status list information includes historical response records of the fire equipment status signal, and the control logic unit verifies signal consistency based on the records.

[0019] The control logic unit is further configured to send a fault alarm to the main controller when the first fire parameter value is inconsistent with the core area signal mode in the status list information.

[0020] Furthermore, the first fire parameter value is obtained through a detector set in the core area of ​​the fire source.

[0021] The second fire condition parameter value is obtained through a detector arranged in the direction of fire spread.

[0022] The state information generating unit associates the second fire condition parameter value with the control node of the spreading direction.

[0023] The control logic unit is configured to prohibit the linkage operation when the second fire condition parameter value is not associated with a correct control node.

[0024] Furthermore, when the master controller starts linkage, it controls the adjacent control nodes to perform at least one of the following operations: Adjust the output intensity of fire-fighting resources.

[0025] Switch the fire fighting equipment working mode.

[0026] The control logic unit is configured to: during the linkage operation, if the fire equipment status signal conflicts with the status list information, terminate the operation and trigger the backup protocol.

[0027] Furthermore, it also includes: Anti-spread barrier devices are deployed at the boundaries of control nodes.

[0028] The master controller is configured to activate the device to physically isolate the fire when the fire threat level exceeds a threshold.

[0029] The state information generating unit records an activation state of the anti-spread barrier device.

[0030] The control logic unit is configured to ignore the isolation instruction when the startup status does not match the status list information.

[0031] Furthermore, it also includes a fire resource distribution module; the main controller is configured to enable the distribution module to provide a set amount of fire extinguishing agent to the target area when the fire threat level exceeds a threshold.

[0032] The set amount is determined based on the fire scene temperature or the available response time.

[0033] The status list information includes output records of the distribution module.

[0034] The control logic is configured to determine that a dispensing failure occurs and to terminate the dispensing when the actual output amount deviates from the recorded value by more than a threshold value.

[0035] Furthermore, it also includes an emergency power supply module; the main controller is configured to enable the emergency power supply module to supply power to key fire-fighting equipment when the fire threat level exceeds a threshold.

[0036] Power supply priority is determined based on the location of the fire or the risk of fire equipment failure.

[0037] The status information generating unit generates a power supply status list of the emergency power supply.

[0038] The control logic unit is configured to disable the power supply and switch to the backup source when the power supply status is inconsistent with the list information.

[0039] Furthermore, the control logic unit is further configured to send a warning message including the fault location to the main controller when the signal is ignored or the fire-fighting equipment is disabled.

[0040] The present invention also provides a method for locating a fire-fighting equipment fault, comprising the following steps: The main controller receives fire protection network data, including fire protection equipment status, deployment location, ambient temperature and fire sensing signals.

[0041] The main controller estimates the control node load based on the fire protection network data.

[0042] The load is compared with a threshold value by the overall controller.

[0043] When the load does not exceed the threshold, the main controller operates in the basic inspection mode.

[0044] When the load exceeds a threshold, the overall controller is operated in an enhanced diagnostic mode.

[0045] The enhanced diagnostic mode performs in-depth detection of fire equipment failures.

[0046] The status information generating unit collects fire-fighting equipment status signals from all control nodes and generates status list information, wherein the status list information associates the fire-fighting equipment status signals with corresponding control nodes.

[0047] Executed by the control logic unit: When the fire equipment status signal is used with a different correspondence with the status list information, the signal is ignored; when the signal in the status list information is used in an unassociated control node, the fault protocol is triggered; in the enhanced diagnostic mode, if the fire equipment status signal conflicts with the status list information, the fire equipment status feedback cycle is shortened and the signal consistency is verified.

[0048] Furthermore, the fire protection network data includes a first temperature value of the fire source core area and a second temperature value of the fire spread area.

[0049] The state information generating unit associates the first temperature value with the core area control node and the second temperature value with the spread area control node.

[0050] The control logic unit is configured to mark the first temperature value as abnormal spread when the first temperature value is inconsistent with the core area signal pattern in the status list information.

[0051] The beneficial effects of this application are as follows: This application can achieve precise control of fire linkage and improve the efficiency of emergency response. Specifically, it divides the fire protection facilities into several control sections. Each control section corresponds to a specific physical node and records the location, equipment function and linkage relationship, laying the foundation for precise linkage. When a fire occurs, the partition control unit analyzes the fire control surface based on the location data and trigger quantity of the fire sensing signal. The main controller judges the threat level based on the fire parameter value in the feedback data, and then determines the linkage range. For example, if the fire source is located in the core area of ​​a certain control section, the comparison of the first fire parameter value (core area data) and the second fire parameter value (spread area data) can accurately assess the fire. The main controller activates the linkage of adjacent control sections accordingly to avoid excessive or insufficient linkage range. This refined division and dynamic evaluation mechanism ensures that the fire linkage control closely fits the actual fire situation, reduces resource waste, quickly curbs the spread of fire, and significantly improves the efficiency of emergency response.

[0052] Furthermore, the control logic unit's consistency check of signals and status lists prevents erroneous activations caused by signals from unrelated control nodes or signals with incorrect mappings. For example, if a device signal is used in an unrelated control node, the system automatically ignores or disables the associated device, preventing unintended activation of devices in unrelated areas from disrupting firefighting operations. This precise linkage control mechanism allows firefighting resources to be focused on the fire area and potential spread paths, maximizing firefighting efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] Figure 2 Flow chart of the method of the present invention. DETAILED DESCRIPTION

[0055] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0057] In some embodiments, the fire detection network, as the system's sensor, collects fire-sensing signals (such as temperature, smoke, and flames) to provide raw data for subsequent fire assessment. These signals are the starting point for the system's fire perception and directly impact the timeliness and accuracy of fire response.

[0058] In some embodiments, the zoned control unit is responsible for regional management and preliminary analysis, communicating with the fire detection network to manage firefighting equipment within predefined control sections. Its core configuration includes two aspects: first, it analyzes the fire control surface (i.e., the fire's impact area and spread) based on the location data of fire sensing signals (e.g., which control section's device triggered the signal) and the number of triggers (how many devices within the same control section responded). This analysis transforms the abstract signal into a concrete description of the fire area; second, it sends real-time feedback data to the master controller, enabling it to monitor the regional fire situation in real time. Furthermore, the zoned control unit is responsible for sending control commands (e.g., activating sprinklers, closing fire doors) to devices within the control section, determining faults when a device fails to respond, and simultaneously obtaining and reporting the functional attributes (e.g., sprinkler, smoke exhaust) and location information of the faulty device, enabling regional-level device control and preliminary fault diagnosis.

[0059] In some embodiments, the master controller serves as the brain of the system, communicating with all partitioned control units and assuming global management and decision-making functions. Its core configuration includes: dividing control nodes according to the layout diagram (subdividing firefighting facilities by physical location, with each control node corresponding to a specific physical node and recording location information); simultaneously recording the functional attributes, connection relationships (such as the piping connections between sprinklers and water pumps), and control linkage relationships (such as a fire in one area triggering smoke exhaust in an adjacent area) of the equipment within each control node; and, after receiving feedback from the partitioned control units, determining whether to activate linkage with adjacent control nodes (for example, when a fire spreads to the boundary of a control node, linking equipment in adjacent areas). This division and recording mechanism lays the foundation for refined management and precise linkage.

[0060] In some embodiments, the status information generation unit is responsible for archiving system status. It collects device status signals (e.g., normal, faulty, and starting) from all control nodes and generates a status list. This list associates the signals with the corresponding control nodes (clarifying which device in which control node is in which state). This list serves as the system's benchmark for determining signal validity and provides data support for subsequent verification.

[0061] In some embodiments, the control logic unit acts as the security guard of the system, responsible for checking the legitimacy of signals and operations to prevent erroneous linkage. Its core configuration includes three verification rules: one is signal correspondence verification. When the correspondence between the device status signal and the status list (such as the signal of device A corresponds to control node 1) does not match, the signal is ignored; the second is control node association verification. When the signal in the list is used for an unassociated control node (such as the signal of control node 1 is used for control node 2), the signal is ignored or the related device is disabled; the third is signal conflict processing. When the signal conflicts with the status list (such as the device displays normal but has no response), the linkage operation containing the signal is prohibited or the backup protocol is triggered (such as enabling the backup device). These rules avoid dangerous operations caused by erroneous signals from the source and ensure the safety of system operation.

[0062] Overall, the system builds a complete fire-fighting linkage control system from fire detection, area analysis, global linkage to fault handling, safety verification by clearly configuring and interacting with each component, and realizes the precision of fire response, the refinement of equipment management, and the safety of system operation. The core innovation lies in the division mechanism of control sections, the multi-level linkage decision-making process, and the full-link signal verification logic, which solves the problems of extensive linkage, fuzzy fault positioning, and high risk of misoperation in traditional systems.

[0063] In some embodiments, the present application can realize precise control of fire linkage, and improve emergency response efficiency. Specifically, by dividing the fire-fighting facilities into several control sections, each corresponding to a specific physical node and recording the location, equipment function and linkage relationship, a foundation is laid for precise linkage. When a fire occurs, the sub-area control unit analyzes the fire control surface based on the position data and trigger quantity of the fire sensing signal, and the total controller judges the threat level combined with the fire parameter value in the feedback data, and then decides the linkage range. For example, if the fire source is located in the core area of a control section, the comparison of the first fire parameter value (core area data) and the second fire parameter value (spreading area data) can accurately assess the fire, and the total controller can start the linkage of adjacent control sections accordingly, avoiding excessive or insufficient linkage range. This fine division and dynamic evaluation mechanism ensures that the fire linkage control closely matches the actual situation of the fire, reduces resource waste, and quickly contains the spread of the fire, significantly improving the efficiency of emergency response.

[0064] At the same time, the control logic unit checks the consistency of the signal and state list to prevent mislinkage caused by non-associated control section signals or incorrect corresponding relationship signals. For example, when a device signal is used in a control section that is not associated, the system automatically ignores or disables the related device to avoid unrelated area device misstart interfering with fire extinguishing action. This precise linkage control mechanism enables fire-fighting resources to focus on the fire area and potential spread path, maximizing fire extinguishing efficiency.

[0065] In some embodiments, the feedback data includes a first fire parameter value and a second fire parameter value; the sub-area control unit determines the fire threat level by comparing the first fire parameter value with the second fire parameter value.

[0066] The total controller determines the linkage range based on the fire threat level; the state list information includes historical response records of the fire-fighting device state signal, and the control logic unit verifies the signal consistency based on the records; the control logic unit is further configured to send a fault alarm to the total controller when the first fire parameter value is inconsistent with the core area signal pattern in the state list information.

[0067] In some embodiments, the first fire parameter value is measured by a temperature sensor located within the detection area. Generally, the reference value for triggering a temperature detector alarm varies in different areas. For example, in well-ventilated corridors, the temperature trigger value is typically set above 50°C (note that the alarm should not be triggered until the temperature reaches 80°C or higher; if this level is reached, a fire hazard is likely imminent). In poorly ventilated areas, the temperature trigger value is typically set at 60°C. Triggering an alarm does not necessarily mean a fire has occurred; rather, it indicates that the temperature is too high, posing a safety hazard. Therefore, the alarm setting range is generally 60-80°C, with the threat level set to Level 1. Temperatures below this range indicate a safe condition. Temperatures between 80-100°C indicate Level 2, necessitating prompt inspection of the corresponding area. Temperatures above 100°C indicate Level 3, indicating a potential fire. It should be noted that the second fire parameter value can be dynamically set based on the first fire parameter value. For example, each node in each area has a basic detection setting, similar to the one described above. However, if a fire breaks out at a node, a second triggering control setting will be set for adjacent nodes. For example, if the temperature detection at the first node triggers a fire alarm, the second nearby node will trigger the second control setting. If the temperature detected is greater than 80°C, the sprinklers will be activated to extinguish the fire. This way, the fire can be contained in the first node area and prevented from spreading.

[0068] In some embodiments, the feedback data explicitly includes a first fire parameter value and a second fire parameter value, which together constitute the core indicator for fire assessment. The first fire parameter value can be understood as key fire data for the core area of ​​the fire source (such as core area temperature and peak smoke concentration), while the second fire parameter value represents data related to the direction of fire spread (such as temperature gradient along the spread path and smoke diffusion rate). These two parameters characterize the fire from the two dimensions of core and spread, providing a more comprehensive basis for determining the threat level.

[0069] In some embodiments, the zone control unit determines the threat level by comparing the first and second fire parameter values. For example, if the first parameter value (core temperature) is extremely high and the second parameter value (spread rate) is high, indicating a severe fire and rapid spread, the threat level is determined to be "severe." If the first parameter value is low and the second parameter value indicates no fire spread, the threat level is determined to be "minor." This multi-parameter comparison is more accurate than a single parameter determination and provides a scientific basis for subsequent linkage scope decisions.

[0070] In some embodiments, this application incorporates a decision-making mechanism for linkage scope. Specifically, the master controller determines the linkage scope based on the fire threat level, enabling on-demand resource allocation. For example, a "minor" level only links equipment within the control section (e.g., activating local sprinklers); a "medium" level links one or two adjacent control sections (e.g., activating smoke exhaust in adjacent areas); and a "severe" level links a wider range (e.g., activating building-wide emergency lighting and closing all fire shutters). This hierarchical linkage mechanism avoids resource waste and ensures effective fire control.

[0071] In some embodiments, the explicit status list information includes historical response records for firefighting equipment status signals (e.g., equipment response time and number of failures over the past three months). The control logic verifies signal consistency based on this record. Specifically, it determines whether the signal is normal by comparing the current signal with historical patterns (e.g., a detector with a historically delayed response may suddenly respond quickly). If the consistency is poor (e.g., a detector with no historical response may suddenly report a fire), it may indicate a device failure or a false alarm, thus improving the accuracy of signal judgment.

[0072] In some embodiments, the control logic has added a core area signal pattern verification function. When the first fire parameter value (core area data) is inconsistent with the core area signal pattern in the status list (such as the core area temperature-time curve pattern in historical fires), a fault alarm is sent to the main controller. For example, if the core area historical pattern indicates that the temperature should continue to rise during a fire, but the current first parameter value fluctuates erratically, the system may determine that there is a detector failure and issue an alarm. This avoids coordinated decisions based on erroneous core data, further improving the reliability of fire assessment.

[0073] In some implementations, by refining fire parameters, grading, coordinated decision-making, and signal verification mechanisms, the system achieves more accurate fire assessments, more rational coordinated control, and more timely fault warnings. Its core value lies in the multi-dimensional application of fire parameters, signal verification logic based on historical data, and specialized verification of core area signal patterns, further enhancing the system's adaptability to complex fire situations and its sensitivity to fault identification.

[0074] In some embodiments, the first fire parameter value is obtained through a detector set in the core area of ​​the fire source; the second fire parameter value is obtained through a detector set in the direction of fire spread; the status information generation unit associates the second fire parameter value with the control node in the direction of spread; the control logic unit is configured to: when the second fire parameter value is not associated with the correct control node, the linkage operation is prohibited.

[0075] In some embodiments, the first fire parameter value is derived from detectors in the core area of ​​the fire source, specifically devices directly monitoring the center of the fire (e.g., temperature detectors and smoke detectors directly above the fire source). These data can directly reflect the core intensity of the fire (e.g., peak temperature and peak smoke concentration). The second fire parameter value is derived from detectors in the direction of fire spread, specifically devices deployed along the potential fire spread path (e.g., downwind of the fire source and in adjacent rooms). These data reflect the speed and extent of the fire spread (e.g., the temperature rise rate along the spread path and the arrival time of smoke). This dual-area data collection model, "core + spread," provides a comprehensive spatial representation of the fire state, avoiding the one-sided nature of data from a single area.

[0076] In some embodiments, the state information generation unit is configured to associate the second fire parameter value with the control node in the direction of spread. This specifies which control node the fire data along the spread path belongs to (e.g., temperature data that spreads to control node 3 is associated with control node 3). This association enables the system to accurately locate the specific area where the fire is spreading, providing spatial coordinates for the subsequent determination of the linked control node, ensuring that the linked operation matches the fire spread path (e.g., activating the fire prevention facilities in control node 3 based on the spread data from control node 3).

[0077] In some embodiments, the control logic unit of the present application includes a linkage prohibition mechanism, which explicitly prohibits linkage operations if the second fire parameter value is not associated with the correct control node. For example, if the temperature data in the spread direction is not correctly associated with control node 3 (e.g., mistakenly associated with control node 4), the system will determine that the data is invalid and prohibit the initiation of linkage with control node 3 based on this data (e.g., closing the fire door of control node 3). This mechanism prevents linkage area deviations caused by data association errors, avoiding control nodes along the fire spread path from losing protection due to lack of linkage, or unrelated control nodes from being mistakenly linked, resulting in waste of resources and confusion.

[0078] In some implementations, by clarifying the spatial location and association rules of fire parameters, fire spread data is precisely linked to control nodes. Combined with a linkage inhibition mechanism, this approach ensures both the spatial accuracy of fire assessments and the regional specificity of linkage control, right from the source of the data. This design addresses the problem of fuzzy correspondence between fire data and regions in traditional systems, leading to misaligned linkage areas. This enables a more precise system response to fire spread and further enhances the effectiveness of fire control.

[0079] In some embodiments, when the main controller starts the linkage, it controls the adjacent control nodes to perform at least one of the following operations: adjusting the output intensity of fire-fighting resources; switching the working mode of fire-fighting equipment; the control logic unit is configured to: in the linkage operation, if the fire-fighting equipment status signal conflicts with the status list information, terminate the operation and trigger the backup protocol.

[0080] In some embodiments, when the total controller initiates the linkage, the adjacent control section needs to perform at least one operation: one is to adjust the output intensity of fire-fighting resources, that is, to adjust the working power or output of the equipment according to the fire demand (for example, when the fire is large, the water pressure of the spray pump is increased to increase the spray intensity; when the fire is small, the speed of the smoke exhaust fan is reduced to reduce energy consumption); the other is to switch the working mode of the fire-fighting equipment, that is, to change the operation mode of the equipment according to the characteristics of the fire (for example, from "local spray" mode to "overall coverage" mode, or from "one-way exhaust" mode to "partitioned flow guide" mode of the smoke exhaust equipment). The linkage of the two operations realizes dynamic adaptation from the two dimensions of resource output and operation mode, ensuring that the fire-fighting equipment can be flexibly adjusted according to the change of the fire, and improving the efficiency of fire extinguishing.

[0081] In some embodiments, the processing logic when the signals conflict: the control logic part adds signal conflict processing rules in the linkage operation, when the fire-fighting equipment state signal and the state list information conflict (for example, the equipment is displayed as "normal" in the list but actually does not respond, or the signal is displayed as "start" but the list records "fault"), the current operation is immediately stopped and the standby protocol is triggered. For example, when the linkage starts the spray system of a control section, it is found that the system signal is displayed as "start" but the state list records that the pipe is damaged and fails, the system determines that the signals conflict, immediately stops the spray start operation, and triggers the standby protocol (such as starting the standby spray system of the adjacent control section). This mechanism avoids the risks that may be caused by forcibly executing linkage operations in abnormal equipment states (such as water damage caused by forcibly spraying water in a damaged pipe, or loss of control of the fire due to the inaction of a faulty equipment), while ensuring the continuity of the fire extinguishing action through the standby protocol.

[0082] In some embodiments, through the specific form of linkage operation and the abnormal processing flow, the linkage control of the system not only can be dynamically adjusted according to the fire, but also can be quickly switched to a safe scheme when the equipment is abnormal, taking into account the flexibility and reliability of the linkage. It solves the problems of single linkage operation of traditional systems and lack of emergency plans in abnormal conditions, ensuring the resource adaptability and operation safety in the linkage process.

[0083] In some embodiments, it also includes a fire spread prevention barrier device deployed at the boundary of the control section; the total controller is configured to start the device to physically isolate the fire when the fire threat level exceeds a threshold; the state information generation part records the start state of the fire spread prevention barrier device; and the control logic part is configured to ignore the isolation instruction when the start state does not match the state list information.

[0084] In some embodiments, the system comprises a barrier device for preventing the spread of fire, which is deployed at the boundary of a control zone (e.g. a fire curtain between adjacent control zones, a door closer linked to a fire wall, a fire damper of a smoke extraction system, etc.), and functions to block the spread path of fire and smoke by physical isolation. The general controller is configured to activate the device when the fire threat level exceeds a threshold (e.g. when the fire has broken through the core control zone and the second fire parameter value indicates that the spread speed is extremely fast). This physical isolation is an important supplement to the linkage of fire-fighting equipment, and can effectively contain the expansion of the fire, buying time for evacuation and fire-fighting rescue.

[0085] In some embodiments, the state information generation unit needs to record the activation state of the barrier device for preventing the spread of fire (e.g. "activated", "not activated", "activation failure"), which provides a basis for the verification of the control logic unit. The control logic unit is configured to ignore the isolation instruction when the activation state does not match the state list information. For example, the state list records that the device is in a "failure" state (cannot be activated), but the general controller issues an "activation" instruction due to a signal error, and the control logic unit verifies that the states do not match, immediately ignoring the instruction, avoiding the invalid operation (e.g. the curtain is stuck and cannot be lowered) or equipment damage (e.g. the motor is overloaded and burned out) caused by forcibly activating a faulty device.

[0086] In some embodiments, by introducing a physical isolation device and establishing a strict state verification mechanism, a dual fire prevention and control system of "active fire extinguishing + physical isolation" is formed. This solves the problem of traditional systems that rely solely on equipment linkage for fire extinguishing and lack effective physical isolation means, or that the isolation device is prone to failure due to lack of operation verification, and improves the reliability of fire spread control, further ensuring the fire safety of the building.

[0087] In some embodiments, a fire-fighting resource allocation module is further included; the general controller is configured to cause the allocation module to provide a set amount of fire extinguishing agent to the target area when the fire threat level exceeds a threshold; the set amount is determined based on the fire temperature or the available response time; the state list information includes the output record of the allocation module; and the control logic unit is configured to determine that the allocation has failed and to stop the allocation when the actual output amount deviates from the recorded value by more than a threshold.

[0088] In some embodiments, the system comprises a fire-fighting resource allocation module, and the general controller is configured to cause the module to provide a set amount of fire extinguishing agent (e.g. dry powder, water, gas, etc.) to the target area when the fire threat level exceeds a threshold. The determination of the set amount is based on the fire temperature (e.g. more fire extinguishing agent is needed for high-temperature areas) or the available response time (e.g. sufficient fire extinguishing agent is needed to control the fire before the fire-fighting personnel arrive), ensuring that the resource allocation matches the fire demand accurately and avoiding under-provisioning or waste.

[0089] In some embodiments, the status list information includes output records from the dispensing module (e.g., the amount of extinguishing agent used and the time of discharge during a particular firefighting event), providing a reference for verification by the control logic. The control logic is configured to determine a dispensing failure and terminate dispensing if the actual output volume deviates from the recorded value by more than a threshold (e.g., a set output of 100L but only 30L is actually output, or a set output of dry powder but only water is actually output). For example, if the deviation threshold is set at 20%, if the actual output volume falls below 80% of the set value, the system will determine a pipeline blockage or pump failure, immediately suspend dispensing, and issue an alarm to prevent the fire from spreading out of control due to insufficient resource supply. If the output medium is incorrect, the operation will be terminated to prevent the incorrect extinguishing agent from exacerbating the fire (e.g., using a water-based extinguishing agent on an electrical fire).

[0090] In some embodiments, an emergency power supply module is also included; the main controller is configured to enable the emergency power supply module to supply power to key fire-fighting equipment when the fire threat level exceeds a threshold; the power supply priority is determined based on the fire location or the risk of fire-fighting equipment failure; the status information generation unit generates a power supply status list of the emergency power supply; the control logic unit is configured to: when the power supply status is inconsistent with the list information, disable the power supply and switch to the backup source.

[0091] In some embodiments, the system includes an emergency power module. The master controller is configured to enable this module to supply power to critical firefighting equipment when the fire threat level exceeds a threshold (e.g., the main power supply has been interrupted by the fire, or the fire threatens the main power lines). Power supply priority is determined based on the location of the fire (e.g., core control equipment near the fire source is prioritized) or the risk of firefighting equipment failure (e.g., emergency lighting equipment failure will result in darkness in evacuation corridors, which is an extremely high risk). This ensures that the most critical equipment can continue to operate even when power resources are limited.

[0092] In some embodiments, the status information generation unit generates a power supply status list for the emergency power supply (e.g., "supplying power to control node 1," "output voltage normal," and "overload protection"). The control logic unit is configured to disable the power supply and switch to the backup source if the power supply status is inconsistent with the list (e.g., the list indicates that a device should be powered first, but is not, or the power supply output voltage far exceeds the standard value). For example, if the emergency power supply output voltage is abnormal due to a short circuit, the control logic unit will verify that it does not match the "voltage normal" status list and immediately disable the power supply and activate the backup generator to prevent the abnormal voltage from damaging the device (e.g., burning out detectors or control modules) or causing equipment shutdown.

[0093] In some embodiments, the emergency power supply prioritizes power and switches during emergency conditions, ensuring power continuity for critical equipment in the event of a fire. This addresses the issues of traditional systems where emergency power supply has no priority and power anomalies cannot be handled promptly, leading to power outages and failures of critical equipment. This ensures the continued operation of the fire protection system.

[0094] In some embodiments, the control logic is further configured to send a warning message containing the fault location to the master controller when a signal is ignored or firefighting equipment is disabled. The control logic is configured to send a warning message containing the fault location to the master controller when a signal is ignored or firefighting equipment is disabled. For example, when a detector signal from a control section is ignored due to a mapping error, or when a smoke exhaust device is disabled because its signal is used in an unassociated control section, the control logic immediately reports the specific fault location to the master controller (e.g., "Detector A signal in control section 5 is abnormal," "Smoke exhaust fan B in control section 3 is disabled"). The core value of this configuration lies in establishing an immediate fault feedback mechanism, allowing management personnel to quickly identify the specific location and device of the abnormality in the system, shortening troubleshooting and repair time. Traditional systems may simply ignore abnormal signals without providing feedback, resulting in long-term hidden faults. However, this claim ensures transparency of fault information, facilitating routine system maintenance and rapid emergency response, further improving system reliability and maintainability.

[0095] The present invention also provides a method for locating fire equipment faults, comprising the following steps: a main controller receives fire network data, including fire equipment status, deployment location, ambient temperature and fire sensing signal; the main controller estimates the control node load based on the fire network data; the main controller compares the load with a threshold; when the load does not exceed the threshold, the main controller operates in a basic inspection mode; when the load exceeds the threshold, the main controller operates in an enhanced diagnosis mode; wherein the enhanced diagnosis mode performs in-depth detection of fire equipment faults; a status information generation unit collects fire equipment status signals from all control nodes and generates status list information, wherein the status list information associates the fire equipment status signal with the corresponding control node; the control logic unit executes: when the fire equipment status signal is used with a different correspondence from the status list information, the signal is ignored; when the signal in the status list information is used in an unassociated control node, the fault protocol is triggered; in the enhanced diagnosis mode, if the fire equipment status signal conflicts with the status list information, the fire equipment status feedback cycle is shortened and the signal consistency is verified.

[0096] In some embodiments, the master controller receives fire protection network data, including fire protection equipment status (e.g., operational, offline), deployment location (control node to which it belongs), ambient temperature (temperature surrounding the equipment, which affects its operation), and fire sensor signals (fire data reported by detectors). Based on this data, the master controller estimates the control node load. Load can be understood as the operating pressure of the equipment within the control node (e.g., the number of devices, signal transmission frequency, and whether high ambient temperature increases the equipment load). Load reflects the likelihood of equipment failure (high load increases the likelihood of equipment failure).

[0097] In some embodiments, the master controller compares the load with a threshold to implement dynamic mode switching. When the load does not exceed the threshold (equipment operation is stable and signal transmission is normal), the master controller operates in basic inspection mode, which detects equipment status at a regular frequency (such as once an hour) and is suitable for daily low-load scenarios. When the load exceeds the threshold (such as frequent signal transmission in equipment-intensive areas, or a sudden rise in ambient temperature), the master controller switches to enhanced diagnostic mode, which performs in-depth detection of fire equipment faults (such as shortening the detection cycle to once a minute and increasing the detection dimensions of equipment response time and communication quality), focusing on troubleshooting potential faults. This dynamic mode switching balances detection accuracy and system resource consumption, avoiding excessive detection and waste of resources under low load or insufficient detection and missed faults under high load.

[0098] In some embodiments, the status information generation unit collects device status signals from all control nodes and generates status list information for associated control nodes, which is consistent with the definition in claim 1. The control logic unit performs three key operations: first, signal correspondence verification. When the device status signal does not match the correspondence in the status list, the signal is ignored; second, cross-control node signal processing. When a signal in the status list is used in an unassociated control node, a fault protocol is triggered (such as reporting a "signal out-of-bounds" fault); and third, conflict processing in enhanced mode. In enhanced diagnostic mode, if the device status signal conflicts with the status list (such as the list displays normally but the device does not respond), the device status feedback cycle is shortened (for example, from once every 5 seconds to once every 1 second) and signal consistency is verified (signal is collected multiple times to confirm whether the conflict persists). This high-frequency verification improves the accuracy of fault diagnosis.

[0099] In some embodiments, a dynamic diagnostic mode switching mechanism and enhanced mode deep verification logic address the issues of traditional fault location methods, such as fixed detection modes, high missed detection rates in high-load scenarios, and inaccurate signal conflict judgment. By combining control node load, state list association, and high-frequency verification, this approach achieves precise fault location and efficient troubleshooting, ensuring that firefighting equipment failures are promptly detected and addressed.

[0100] In some embodiments, the fire network data includes a first temperature value of the fire source core area and a second temperature value of the spread area; the status information generation unit associates the first temperature value with the core area control node and the second temperature value with the spread area control node; the control logic unit is configured to: when the first temperature value is inconsistent with the core area signal pattern in the status list information, it is marked as abnormal spread.

[0101] In some embodiments, the fire network data includes a first temperature value of the fire source core area (core area temperature, reflecting the intensity of the fire) and a second temperature value of the spread area (spread path temperature, reflecting the diffusion trend), which echoes the parameter definitions in claims 2 and 3, and enhances the integrity of the fire data from the temperature dimension.

[0102] In some embodiments, the status information generator associates the first temperature value with the core zone control node (to clearly identify the core zone temperature), and the second temperature value with the spread zone control node (to clearly identify the spread zone temperature). This association enables the system to accurately locate the spatial location of temperature changes, providing a coordinate reference for determining the fire spread path.

[0103] In some embodiments, the control logic is configured to flag an abnormal spread when the first temperature value is inconsistent with the core area signal pattern in the status list information. The core area signal pattern can be understood as the temporal pattern of core area temperature changes in historical fires (e.g., in normal fires, the temperature should continuously rise, and the rate of rise is positively correlated with the fire intensity). For example, if the current first temperature value fluctuates, inconsistent with the "continuously rising" pattern recorded in the status list, the control logic may determine that there is a detector failure (e.g., data distortion due to detector aging) or an abnormal fire (e.g., a sudden flare-up from a smoldering state), flag it as abnormal spread, and prompt further investigation.

[0104] This application establishes an efficient fault location mechanism, shortening the troubleshooting cycle. The system's fault location mechanism enables rapid identification and precise location of equipment faults from multiple dimensions. After the partition control unit sends a control command to the device, if there is no response within a set period, it determines a fault and simultaneously obtains the functional attributes and location information of the faulty device and reports it. This allows management personnel to quickly determine the specific location and functional type of the faulty device (such as sprinkler systems, smoke exhaust equipment, etc.), providing precise guidance for maintenance.

[0105] The status list generated by the status information generation unit associates device signals with control nodes. The control logic unit verifies the correspondence between the signals and the list to identify the source of abnormal signals. For example, if the device status signal is inconsistent with the control node association of the status list, the system can quickly determine that the signal anomaly may be due to a device failure and trigger the corresponding fault protocol. In enhanced diagnostic mode, the main controller initiates deep testing based on loads exceeding the threshold, shortening the device status feedback cycle and verifying signal consistency, further improving the accuracy and timeliness of fault identification.

[0106] Compared with the traditional fault judgment method that relies on a single signal, this mechanism combines the device response status, location information, functional attributes and historical records, greatly reducing the misjudgment rate, shortening the fault location time, ensuring that the faulty equipment can be quickly repaired or replaced, and protecting the integrity of the system in the event of a fire.

[0107] This application enhances the reliability of system operation and reduces the risk of misoperation. Specifically, the multiple verification mechanism of the control logic unit provides reliable protection for system operation. When there is a conflict between the device status signal and the status list information (such as signal correspondence error, signal usage area error, etc.), the system prevents the execution of erroneous instructions by ignoring the signal, disabling the device, or prohibiting linkage operations. For example, if a detector sends an erroneous fire signal due to a fault, and the signal is inconsistent with the core area signal pattern in the status list, the control logic unit will send a fault alarm to the main controller and prohibit linkage based on the signal to avoid misoperation.

[0108] The status list contains historical device response records. The control logic uses this information to verify signal consistency, identify persistent signal anomalies, and provide early warning of potential failures. For example, if a device repeatedly experiences delayed responses and the deviation between the historical record and the current signal exceeds a threshold, the system can identify a hidden fault and initiate maintenance, preventing failure at a critical moment.

[0109] Furthermore, the backup protocol triggering mechanism provides emergency protection in the event of signal conflicts. If a core linkage operation cannot be executed due to a signal conflict, the system automatically activates the backup protocol to ensure the implementation of basic firefighting functions (such as activating backup sprinkler systems and switching smoke exhaust paths). This reduces safety risks caused by system anomalies and significantly improves system reliability in complex operating conditions.

[0110] This application optimizes firefighting resource allocation and improves resource utilization efficiency. The master controller uses a mechanism to determine the scope of linkage based on the fire threat level, enabling dynamic optimization of firefighting resource allocation. The zoning control unit determines the threat level by comparing the first fire parameter value (core zone data) with the second fire parameter value (spread zone data). The master controller adjusts the linkage intensity accordingly. Low-level threats only activate the equipment in the control section and a small adjacent area, while high-level threats expand the linkage scope and mobilize more resources (such as increasing sprinkler intensity and activating multiple sets of smoke exhaust equipment). This on-demand allocation model avoids unnecessary resource consumption and ensures resource supply in key areas.

[0111] The firefighting resource allocation module determines the required amount of fire extinguishing agent based on the fire temperature or available response time, precisely matching resource delivery to the fire intensity. For example, high-temperature fires automatically increase extinguishing agent delivery, while smaller fires in the early stages have their delivery reduced, ensuring effective extinguishing while minimizing waste. The emergency power supply module prioritizes power delivery based on the fire's location and the risk of equipment failure, ensuring that critical equipment (such as sprinkler pumps and emergency lighting in the core area) receives power first, enhancing targeted resource utilization.

[0112] The division of control sections enables more refined resource management. The functional attributes and connection relationships of devices within each section are clearly recorded, allowing the master controller to quickly allocate and adapt resources based on device functions. For example, in an electrical fire area, gas fire extinguishing equipment is prioritized over water-based sprinklers, improving resource efficiency.

[0113] This application strengthens emergency response security. The deployment and coordinated control of anti-spread barrier devices provide a key guarantee for fire isolation. When the fire threat level exceeds the threshold, the master controller activates the barrier devices (such as fire curtains and smoke exhaust and fire dampers) at the control node boundary to physically isolate the fire spread path. The status information generation unit records the device startup status, and the control logic unit verifies the consistency of the status with the list. If the startup is abnormal, the erroneous instruction is ignored and a fault is prompted, preventing the fire from getting out of control due to barrier failure. This physical isolation mechanism buys valuable time for personnel evacuation and firefighting operations, reducing the risk of fire spread.

[0114] The system's rigorous verification of the core zone signal pattern ensures accurate fire assessment. If the primary fire parameter value is inconsistent with the core zone signal pattern, the system issues a fault alarm, indicating a possible false alarm or detector failure. This prevents unnecessary evacuation and resource waste caused by misjudgments of fire. For example, if a detector reports a fire despite no noticeable high temperature in the core zone, the system will immediately sound an alarm and suspend coordination, awaiting manual confirmation before taking action, ensuring the safety of decision-making.

[0115] The control logic prohibits dangerous linkage operations when signals conflict, preventing equipment misoperation from endangering personnel. For example, if an abnormal signal from a smoke exhaust device could cause reverse exhaust (directing smoke into the evacuation corridor), the system immediately prohibits the operation and activates a backup exhaust path, ensuring a smoke-free evacuation corridor. This strict control over risky operations significantly enhances the safety of personnel and property during emergency response.
