Description

Technical Field

[0001] This invention relates to the field of training equipment technology, and in particular to a portable subway FAS and gas extinguishing system simulation training device. Background Technology

[0002] In the subway operation safety assurance system, the automatic fire alarm system (FAS) and the gas extinguishing system are crucial. The subway environment is complex and densely populated, so in the event of a fire, rapid and accurate alarms and effective fire extinguishing measures are key to ensuring the safety of people's lives and property.

[0003] However, current training on subway FAS and gas extinguishing systems mainly relies on theoretical instruction and field visits, lacking simulations of real-world scenarios. On-site training has many limitations, such as disrupting normal subway operations and being unable to simulate various malfunctions and emergency situations. Furthermore, existing simulation training devices are mostly bulky and fixed in place, making them difficult to move and adjust flexibly according to training needs, and thus unable to meet diverse training scenarios and requirements. Therefore, developing a flexible, mobile training device capable of comprehensively simulating subway FAS and gas extinguishing systems is of significant practical importance. Summary of the Invention

[0004] The purpose of this application is to provide a portable subway FAS and gas extinguishing system simulation training device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: including a base and a control system, wherein a simulation panel is fixedly installed on the top of the base, and the simulation panel integrates a fire alarm simulation device, a fire extinguishing control simulation device, a gas extinguishing device and a ventilation simulation device; A fire alarm simulation device, including but not limited to the simulation of smoke detectors, temperature detectors, and fire detectors, wherein each alarm simulation is an alarm light fixed on the simulation panel; A fire extinguishing control simulation device, comprising a gas extinguishing control device and a section control device, wherein the section control device is used to change the subway section currently being simulated, and the gas extinguishing control device is used to connect to the gas extinguishing device and control the gas extinguishing device to perform gas extinguishing operation.

[0008] A further feature of the present invention is that a bracket for supporting the simulation panel is fixedly installed on the base, and the bottom of the base is provided with casters.

[0009] A further provision of the present invention is that a power supply for supplying power to each electrical simulation device is fixed on the back of the simulation panel.

[0010] A further feature of the present invention is that the simulation panel is also integrated with an auxiliary simulation device, which is used to simulate the indicator lights of the fire pump, access control and broadcast status in the subway.

[0011] The present invention is further configured such that the control system includes a signal acquisition and processing module, a subway section dynamic mapping and zoning control module, a FAS and gas extinguishing system full logic linkage control module, a multi-dimensional fault condition injection and emergency response simulation module, a multi-equipment collaborative ventilation and auxiliary system linkage control module, a hierarchical permission management and operation full process traceability module, a standardized training assessment and intelligent scoring module, and a mobile device safety interlock and power supply management module. The signal input terminal of the signal acquisition and processing module is connected to the fire alarm simulation device on the simulation panel. It is used to acquire electrical signals of various fire detection triggering elements, perform feature fitting and normalization transformation on the acquired signals corresponding to the actual operating characteristics of the detector, and has a built-in signal variation simulation unit for reproducing the non-ideal operating characteristics of the detector. At the same time, it provides an open signal parameter visualization adjustment interface and finally transmits the processed standardized signal to the main control unit. The metro section dynamic mapping and partition control module interfaces with the section control device on the simulation panel. It has a built-in metro full-line section topology database and a visual section topology configuration tool, which is used to complete the dynamic loading of system configuration and linkage logic according to the selected simulation section, and at the same time establish the association and coupling relationship between adjacent sections to realize cross-section linkage control. The signal input terminal of the FAS and gas extinguishing system full logic linkage control module is connected to the signal acquisition and processing module and the metro section dynamic mapping and zoning control module. The output terminal is connected to the gas extinguishing control device and gas extinguishing device on the analog panel. It has a built-in full-process linkage logic that complies with national fire protection standards and metro industry operation standards. It is used to complete the fire confirmation logic judgment and output the graded linkage signal, realizing the full logic closed-loop control from fire alarm, gas extinguishing pre-start, delay control, emergency start and stop to discharge feedback. The multi-dimensional fault condition injection and emergency response simulation module is bidirectionally connected to all other functional modules and has a built-in hierarchical fault condition library. It is used to inject preset fault conditions into the system at any node of the training process to reconstruct the system's operating status, while simultaneously recording the trainee's entire fault handling operation data. The signal input end of the multi-device collaborative ventilation and auxiliary system linkage control module is connected to the FAS and gas extinguishing system full logic linkage control module, and the output end is connected to the ventilation simulation device and auxiliary simulation device of the simulation panel. It is used to realize the collaborative linkage control of the ventilation system with fire pump, access control and broadcast auxiliary system in fire scenario. At the same time, it reserves a linkage signal output interface for connecting with real field equipment. The hierarchical permission management and full-process operation traceability module is bidirectionally connected to all functional modules and has a built-in three-level permission control system to realize differentiated permission control for different operation roles. At the same time, it uses high-precision timestamps to encrypt and store the operation behavior data of the entire training process, so as to realize the traceability and review of the training process. The standardized training assessment and intelligent scoring module is interconnected with the hierarchical permission management and full-process operation traceability module. It has a built-in multi-dimensional standardized assessment question bank to collect all the operation data of trainees during the assessment process, and to complete the quantitative intelligent scoring of training effectiveness and the generation of standardized assessment reports. The mobile device safety interlock and power supply management module is electrically connected to all functional modules. It has a built-in mobile safety interlock unit, intelligent power supply management unit and hardware reliability assurance unit. It is used to realize safety interlock control of the mobile device, dual power supply redundancy management and real-time monitoring and early warning of the device hardware operation status. At the same time, it adopts a modular and customizable architecture to adapt to different budgets and training needs.

[0012] A further feature of this invention is that the multi-dimensional fault condition injection and emergency response simulation module adopts an atomic fault injection design. Each fault condition is an independently encapsulated execution unit with a dedicated independent clearing instruction and a one-click reset mechanism. At the same time, a hardware-level watchdog timer is built-in. The watchdog timer is used to monitor the system's operating status in real time. When a logical deadlock is detected in the system due to fault injection, the system status is automatically reset to restore the system to normal operating status.

[0013] A further feature of this invention is that the standardized training assessment and intelligent scoring module adopts a flexible scoring architecture, which supports the visual configuration of multiple correct handling paths under the same assessment scenario. At the same time, it adopts a scoring strategy of "critical node must be reached + time sequence tolerance", which sets only fire confirmation, emergency response closure, and safety measure implementation as critical scoring nodes that must be reached, and sets an adjustable time sequence tolerance for the execution order of non-critical operations, thereby completing unbiased intelligent scoring of trainees' operations.

[0014] A further provision of this invention is that the mobile safety interlock unit of the mobile device safety interlock and power supply management module acquires the device's operating status through a non-contact Hall displacement sensor and a high-precision tilt sensor. It incorporates a built-in delay filtering unit and a hysteresis comparison algorithm unit. The delay filtering unit filters out instantaneous trigger signals caused by slight device vibrations, and the hysteresis comparison algorithm unit prevents false triggering caused by signal jitter at the tilt threshold edge. The hardware reliability assurance unit uses industrial-grade aviation plugs and drag chain flexible cables, and incorporates real-time monitoring functions for cable continuity and connector contact status. It also reserves a standard industrial real I / O output module interface to accommodate hardware-in-the-loop training requirements.

[0015] In summary, the technical effects and advantages of this invention are as follows: I. Mobility: The base is equipped with casters, which makes it easy to move the simulation training device to different training venues, such as subway training centers and construction sites, to meet diverse training needs and improve the flexibility and convenience of the device.

[0016] II. Comprehensive Simulation Functions: The simulation panel integrates fire alarm simulation devices, fire extinguishing control simulation devices, gas extinguishing devices, ventilation simulation devices, and auxiliary simulation devices. It can comprehensively simulate various functions and scenarios of subway FAS and gas extinguishing systems, including fire alarm, gas extinguishing operation, ventilation control, and the status of fire pumps, access control, and broadcasts. It provides trainees with a realistic and complete training environment, which helps to improve their practical operation and emergency response capabilities.

[0017] 3. Visual Demonstration: The fire alarm simulation device visually simulates the alarm status of various alarms through alarm lights, and the exhaust simulation device clearly displays the working status of the exhaust fan through the corresponding status lights of the air valves, enabling trainees to observe and understand the system's operation more intuitively and reducing the difficulty of training.

[0018] IV. Flexible Section Simulation: The section control device in the fire extinguishing control simulation device can change the current subway section being simulated, and can simulate fire situations in different subway sections, increasing the diversity and relevance of training.

[0019] V. The control system, through sequentially linked functional modules, constructs a complete closed-loop control system for the simulation training of subway FAS and gas extinguishing systems. Firstly, the signal acquisition and processing module achieves high-fidelity simulation of the real signal characteristics of different types of fire detectors. The built-in signal variation simulation unit can reproduce the non-ideal signal characteristics caused by environmental temperature, dust, and aging. Simultaneously, an open sensitivity parameter adjustment interface breaks through the limitations of existing technologies' binary state simulation and signal idealization distortion, making the training scenario more closely resemble the real operating environment and preventing a disconnect between training and on-site practice. Secondly, through the subway section dynamic mapping and zoning control module, coupled with a visual drag-and-drop configuration tool, the dynamic topology of the subway sections is realized. The mapping and adjacent interval coupling linkage, while supporting custom configuration, can adapt to the subway station structures and system configurations of different cities and lines, greatly improving the versatility and applicability of the device, while reducing the system maintenance threshold; through the FAS and gas extinguishing system full logic linkage control module, with built-in full-process linkage logic conforming to national standards and subway industry specifications, a complete linkage closed loop from fire confirmation, pre-start, delay control, emergency start and stop to discharge feedback is realized, making training content fully aligned with actual operation, solving the problem of the disconnect between existing training and practice; through the multi-dimensional fault condition injection and emergency response simulation module, adopting an atomic fault injection design, built-in faults covering the entire system are... The system includes a fault database, with each fault accompanied by an independent clearing command and a one-click reset mechanism. A hardware watchdog timer prevents system deadlock, allowing faults to be injected and cleared at any point during the training process. This enables practical, highly stable emergency response training, comprehensively improving trainees' emergency response capabilities and filling the gaps in existing technologies that prevent fault emergency training or where fault injection can easily lead to training interruptions. Through a multi-device collaborative ventilation and auxiliary system linkage control module, the system achieves coordinated control of ventilation, fire pumps, access control, and broadcasting systems in fire scenarios, fully replicating the collaborative working logic of multiple systems under subway fire conditions, making the training scenarios more comprehensive. Hierarchical access control and full-process operation traceability are also included. The module constructs a three-level access control system, realizing full-process, tamper-proof traceability of operational behavior. This not only avoids system configuration errors caused by misoperation but also enables comprehensive review of the training process. Through the standardized training assessment and intelligent scoring module, a flexible multi-path scoring architecture is adopted, supporting the configuration of multiple correct handling paths. The scoring strategy of "critical node must be reached and time sequence tolerance" replaces the traditional strict sequence comparison mode, which can effectively avoid misjudgment of non-standard but compliant handling methods. At the same time, a visual scoring rule configuration tool is provided to realize the quantitative evaluation and intelligent scoring of training effectiveness, solving the problems of existing training assessment relying on subjective judgment, inability to quantify effectiveness, and rigid scoring mechanisms.Through a mobile device safety interlock and power supply management module, a dual anti-shake and anti-accidental-touch safety interlock mechanism with delay filtering and hysteresis comparison is constructed to address the mobile nature of the device. It adopts industrial-grade high-reliability connectors and cable design, and simultaneously realizes intelligent power supply management and dual-power redundant switching. This eliminates safety hazards, sensor false triggering risks, and hardware reliability issues during the movement of the mobile device, while ensuring continuous and stable operation during training. It also reserves real I / O interfaces for compatibility with hardware-in-the-loop simulation and adopts a modular, customizable design to adapt to different budget requirements, significantly reducing the application threshold and cost of the system. Overall, this control system not only realizes full-scenario, full-process, and practical simulation training of subway FAS and gas fire extinguishing systems, greatly improving training quality and trainees' practical and emergency response capabilities, but also possesses strong versatility, safety, maintainability, and high cost-effectiveness.

[0027] Example: A portable subway FAS and gas extinguishing system simulation training device includes a base 1, on the top of which a simulation panel 2 is fixedly installed. The simulation panel 2 integrates a fire alarm simulation device 3, a fire extinguishing control simulation device 4, a gas extinguishing device 5, and a ventilation simulation device 7.

[0028] Fire alarm simulation device: including but not limited to alarm simulation of smoke detectors, temperature detectors, and fire detection alarms. Each alarm simulation is an alarm light fixed on the simulation panel 2. The illumination of the alarm light simulates the alarm status of different types of alarms 3.

[0029] Fire extinguishing control simulation device: includes gas extinguishing control device 13 and section control device 14. Section control device 14 is used to change the subway section where the current simulation is located. Gas extinguishing control device 13 is used to connect to gas extinguishing device 5 and control gas extinguishing device 5 to perform gas extinguishing operation 4.

[0030] Ventilation simulation device: includes an exhaust fan 9 fixed on the simulation panel 2 and several air valves 8 that control the air force of the exhaust fan 9. Each air valve 8 is connected to a status light. The different working states 7 of the exhaust fan 9 are simulated by adjusting the air valves 8 and displaying the status lights.

[0031] Other configurations: The gas extinguishing device 5 is fixed to the ground with bolts; the simulation panel 2 also integrates an aspirating detector 15; the base 1 is fixedly installed with a bracket 10 to support the simulation panel 2; the back of the simulation panel 2 is fixed with a power supply 12 to supply power to each electrical simulation device; the simulation panel 2 also integrates an auxiliary simulation device 6, which is used to simulate the status of the fire pump, access control and broadcast in the subway.

[0032] This simulation training device is used to conduct training on subway fire suppression systems (FAS) and gas extinguishing systems in a training scenario at a subway training center.

[0033] Device movement and installation: Because the base 1 has casters 11 at its bottom, trainees can easily move the device to the training room. Once in the designated location, ensure the device is placed stably and check that the gas extinguishing device 5 is securely fixed to the ground with bolts to ensure the device's stability during training.

[0034] Fire Alarm Simulation: The instructor operates the simulation system to trigger the fire alarm simulation device 3. For example, when a smoke alarm is simulated, the corresponding alarm light illuminates, visually demonstrating the smoke alarm situation to the trainees. Trainees can clearly see the status of the alarm lights when different types of alarms are activated, deepening their understanding of the fire alarm mechanism.

[0035] Fire Extinguishing Control Simulation: The instructor uses the section control device 14 to select a simulated subway section, and then operates the gas extinguishing control device 13 to control the gas extinguishing device 5 to perform a simulated gas extinguishing operation. Students can observe the simulated actions of the gas extinguishing device 5 and understand the activation process and control methods of the gas fire extinguishing system in different sections.

[0036] Ventilation Simulation: The instructor adjusts valve 8 of the ventilation simulation device 7 to change the airflow of the exhaust fan 9. The status light corresponding to valve 8 displays different states according to the adjustment of valve 8, allowing trainees to intuitively see the changes in the working status of the exhaust fan 9 and learn the control and adjustment methods of the ventilation system in a fire situation.

[0037] Auxiliary Simulation: The instructor uses auxiliary simulation device 6 to simulate different states of fire pumps, access control systems, and public address systems within the subway system. For example, when a fire pump starts, the corresponding indicator light illuminates; when an access control system opens or closes, the corresponding indicator light also changes status. Participants can gain a comprehensive understanding of the operational status and interrelationships of various auxiliary devices in the subway fire protection system.

[0038] Throughout the training, the aspirating detector 15 integrated on the simulation panel 2 simulates actual ventilation conditions, creating a more realistic training environment for the trainees. Simultaneously, the power supply 12 on the back of the simulation panel 2 provides a stable power supply to all electrical simulation devices, ensuring the training proceeds smoothly. Through this training method, trainees can systematically learn and master the operation and emergency response skills of subway FAS and gas fire suppression systems in a portable, fully simulated environment.

[0039] As another embodiment, it may also include a control system, which includes a signal acquisition and processing module, a subway section dynamic mapping and zoning control module, a full logic linkage control module for FAS and gas extinguishing system, a multi-dimensional fault condition injection and emergency response simulation module, a multi-equipment collaborative ventilation and auxiliary system linkage control module, a hierarchical permission management and full-process operation traceability module, a standardized training assessment and intelligent scoring module, and a mobile device safety interlock and power supply management module. In this embodiment, the signal acquisition and processing module serves as the core of the control system's underlying input, directly interfacing with the fire alarm simulation device and aspirating detector hardware on the simulation panel. The module incorporates multiple signal acquisition channels to acquire real-time switching and analog signals from various triggering elements on the simulation panel (simulating smoke / temperature / fire detectors and manual / automatic triggering units for aspirating detectors). Based on the actual operating characteristics of different types of detectors, the module performs feature fitting and normalization processing on the acquired signals, including simulating the slow-rise signal characteristics of photoelectric smoke detectors, the threshold triggering characteristics of constant-temperature detectors, the temperature rise rate triggering characteristics of differential-temperature detectors, and the multi-level warning characteristics of aspirating detectors. The module also includes a built-in signal variation simulation unit, which can superimpose random disturbances of the "signal variation coefficient" based on the environmental impact data of real detectors to simulate non-ideal characteristics such as signal drift, sensitivity attenuation, and abnormal noise caused by environmental temperature changes, dust accumulation, and device aging, thus avoiding overly idealized simulated signals. Simultaneously, the module provides a full-parameter visual adjustment interface, allowing trainers to directly adjust the signal sensitivity, alarm threshold, and variation coefficient range of various detectors according to training needs, without modifying the underlying code, to reproduce the detector signal characteristics under different aging levels and operating environments. Ultimately, all differentiated signals are converted into standard CAN bus data frames and transmitted to the main control unit, providing standardized, high-fidelity input signals for upper-level linkage control. This module breaks through the limitation of existing technologies that can only simulate binary "alarm / non-alarm" states, achieving high-fidelity reproduction of the signal characteristics of real detectors under all operating conditions, thus avoiding a disconnect between training and on-site practice.

[0040] In this embodiment, the metro section dynamic mapping and zoning control module interfaces with the section control device on the simulation panel, providing a scenario-based configuration foundation for the control system. The module has a built-in metro full-line section topology database, storing station structures, smoke control zone divisions, FAS point configurations, and gas extinguishing system protection area parameters for different metro lines. The module is equipped with a visual section topology configuration tool, using a drag-and-drop graphical interface. Non-developers do not need coding knowledge to add, modify, delete, and update metro line section topology, smoke control zone divisions, FAS point configurations, and gas extinguishing system protection area parameters. It also supports one-click import, export, backup, and restore of configuration data, significantly reducing the system maintenance threshold. After trainees select a simulated section through the section control device, the main control unit completes the dynamic mapping of the current simulated section, automatically loading the corresponding system configuration and linkage logic for that section. Simultaneously, it establishes the correlation and coupling relationship between adjacent sections, incorporating the equipment status of adjacent sections into the linkage judgment conditions, enabling the linkage status switching of adjacent sections triggered by a fire at this station. The module also provides a custom configuration interface, allowing users to customize section topology, point configurations, and linkage rules according to the actual situation of the target line, adapting to the metro system configurations of different cities and lines without modifying the hardware. This module addresses the problems of isolated section simulation, lack of cross-section linkage, poor versatility, and high maintenance threshold in existing technologies, enabling flexible simulation and low-threshold maintenance of the entire subway line.

[0041] In this embodiment, the FAS and the gas extinguishing system full logic linkage control module is the core linkage hub of the control system. It directly interfaces with the gas extinguishing control device and gas extinguishing device hardware on the simulation panel, and has built-in full-process linkage logic that fully complies with the "Code for Design of Automatic Fire Alarm System" (GB50116), "Code for Design of Gas Extinguishing System" (GB50370) and the subway industry operation specifications. The module's workflow is as follows: After receiving the normalized detection signal, it first executes a fire confirmation logic judgment, supporting "AND / OR" logic combinations (a fire is confirmed only when two independent detectors in the same smoke control zone alarm). Upon fire confirmation, it immediately outputs a tiered linkage signal. The first signal triggers the alarm lights and audible / visual alarms of the fire alarm simulation device; the second signal locks the fire zone through the zone control module, initiates the pre-start process of the gas extinguishing control device, and triggers a 0-30s adjustable delay countdown; the third signal sends a collaborative control command to the auxiliary linkage module. During the delay phase, the module receives an emergency stop signal in real time. If a valid stop signal is received, the gas extinguishing start process is immediately terminated. If no stop signal is received by the end of the delay, a discharge command is output to trigger the simulated discharge of the gas extinguishing device. Simultaneously, the discharge feedback signal of the gas extinguishing device is collected in real time, completing the entire logical closed loop from fire detection to fire extinguishing execution. The module also supports manual / automatic mode switching, replicating the local / remote control permission switching logic of the gas extinguishing control panel. This module solves the problems of existing technologies that can only achieve single-point state simulation, lack standardized linkage closed loops, and have a disconnect between training and practical operation.

[0042] The multi-dimensional fault condition injection and emergency response simulation module is linked with all basic modules of the signal acquisition and processing module, the metro section dynamic mapping and zoning control module, and the FAS and gas extinguishing system full logic linkage control module. It has a built-in hierarchical fault condition library, divided into four categories: detector faults, gas extinguishing system faults, linkage system faults, and power supply faults. This covers various high-frequency real-world fault scenarios in metro operation, including detector false alarms / offline status, gas extinguishing valve jamming, missing discharge feedback, ventilation system failure, and linkage power supply failure. The module adopts an atomic fault injection design, with each fault condition being an independently encapsulated execution unit, equipped with a dedicated independent clearing command and a one-click reset mechanism. Fault injection and clearing operations do not interfere with each other, avoiding logical conflicts caused by multiple faults overlapping. Simultaneously, the module has a built-in hardware-level watchdog timer to monitor the system's operating status in real time. When a logical deadlock or abnormal state is detected due to fault injection, the system can automatically perform a state reset within a set time, clearing all injected faults and restoring the system to normal standby state without requiring a system restart, ensuring the continuity of the training process. The module is implemented as follows: Trainers can inject preset fault conditions into the control system at any point in the training process via a host computer or control panel. Upon receiving the fault injection command, the main control unit immediately modifies the corresponding module's operating parameters and logical judgment conditions, reconstructing the system's operating state. For example, when injecting a "missing feedback for gas extinguishing and discharge" fault, even if the main control unit outputs a discharge command, the feedback signal from the gas extinguishing device is blocked, triggering a fault alarm and guiding trainees to execute emergency response procedures. During training, trainers can clear individual or all injected faults at any time using independent clear commands, restoring the system to normal operation. The module also records the trainees' entire operational steps for each fault condition in real time using timestamps, synchronizing this data to the traceability module in step 6 and the assessment module in step 7, providing data support for training review and assessment. This module fills the gap in existing technologies that cannot conduct fault emergency response training and where fault injection easily leads to system deadlock and interruption training, achieving practical and highly stable emergency scenario training.

[0043] The multi-device collaborative ventilation and auxiliary system linkage control module interfaces with the ventilation simulation device and auxiliary simulation device on the simulation panel, and receives the core linkage command of the FAS and gas extinguishing system full logic linkage control module to realize the collaborative linkage control of multiple systems in fire scenarios. The module's operating logic is as follows: After fire confirmation, the main control unit automatically calculates and outputs exhaust control parameters based on the fire zone and smoke control zone locked by the subway section dynamic mapping and zoning control module. This controls the start / stop of exhaust fans and the opening adjustment of air valves in the corresponding areas. Simultaneously, the operating status of exhaust fans and air valves is displayed in real time through the status lights corresponding to the air valves, replicating the smoke exhaust / pressurization logic under fire conditions. At the same time, linkage commands are sent to the auxiliary simulation device, synchronously triggering the switching of status indicator lights corresponding to fire pump start-up, access control release, and emergency broadcast activation. This fully replicates the collaborative linkage logic of the fire protection, access control, broadcasting, and FAS systems under a subway fire scenario. The module also links with the fault injection module in step 4, simulating auxiliary system faults such as smoke exhaust valve jamming, fire pump start-up failure, and access control linkage failure, triggering corresponding fault alarms and guiding trainees to execute the handling procedures. The module reserves a linkage signal output interface, which can interface with the real I / O expansion module in step 8 to achieve linkage control of real equipment on site. This module solves the problem that existing auxiliary systems can only achieve single-point status display and lack collaborative linkage logic, realizing a complete simulation of the entire system linkage scenario.

[0044] The hierarchical access control and full-process operation traceability module is the core of the control system's access control and data management. It features a built-in three-tier access control system: instructor administrator access, trainer access, and student access. Different access levels correspond to different operational scopes: instructor administrators can modify system linkage logic, maintain the fault condition database, manage all user information, and configure all system parameters; trainers can select training scenarios, inject and clear fault conditions, view all student operation records, and adjust assessment scoring rules; student access is limited to simulated operations and assessments, and cannot modify any system configurations, thus preventing system configuration errors caused by accidental operations. Simultaneously, the module includes a built-in full-process operation traceability unit. Using high-precision timestamps, it records all operational behaviors during training in real time, including detector triggering operations, interval switching operations, gas extinguishing system control operations, fault handling steps, and system status changes. All records are encrypted, tamper-proof, and automatically saved to local storage, supporting export and viewing at any time, enabling full-process review of the training process.

[0045] The standardized training assessment and intelligent scoring module is the core of the control system's training effectiveness evaluation. It interconnects with the traceability module of the hierarchical access control and full-process operation traceability module, and includes multiple standardized assessment question banks categorized into three main types: basic operation assessment, linkage process assessment, and emergency response assessment, covering all dimensions of assessment needs from basic operations to emergency response. The module adopts a flexible scoring architecture, supporting the visual configuration of multiple correct handling paths. Trainers can preset multiple compliant handling procedures for the same fault scenario in the configuration tool according to subway operation regulations. It employs a core scoring strategy of "mandatory key node achievement + time sequence tolerance," replacing the traditional strict sequence comparison mode: only core operations such as fire confirmation, emergency response closure, and safety measure implementation are set as mandatory key nodes, serving as the core scoring basis. Adjustable time sequence tolerances are set for the execution order of non-critical operations. Trainees only need to complete all key nodes and avoid performing any illegal or dangerous operations to obtain the corresponding score, avoiding misjudgments of non-standard but compliant and effective handling methods. The module's workflow is as follows: Before the assessment begins, the trainer selects the assessment type, difficulty, and duration. The system automatically loads the corresponding assessment scenario, multi-path scoring criteria, and quantitative scoring weights. During the assessment, the system collects data in real time on the trainee's operational steps, operational sequence, handling results, and response time, comparing this data with preset standard rules. After the assessment, the system automatically completes intelligent scoring based on preset scoring weights. Scoring dimensions include four categories: completeness of the operational process, completion of key nodes, effectiveness of fault handling, and emergency response time. Simultaneously, a standardized assessment report is automatically generated, marking the trainee's erroneous operations, violations, and areas for improvement. The module is equipped with a visual scoring rule configuration tool, allowing non-developers to customize assessment scenarios, key nodes, scoring weights, and tolerance ranges according to the training specifications of their respective subway operating company, adapting to differentiated assessment needs. This module addresses the problems of existing technology training effectiveness being unquantifiable, assessments relying on subjective judgment, and rigid scoring mechanisms prone to misjudgments, achieving standardized, digitalized, and flexible evaluation of training effectiveness.

[0046] The mobile device safety interlock and power management module is a dedicated safety guarantee and hardware adaptation core designed for the mobile characteristics of the device. It directly interfaces with the mobile wheels, support bracket, and power hardware on the back of the analog panel of the device base. It is divided into four core units: mobile safety interlock unit, intelligent power management unit, hardware reliability guarantee unit, and modular function expansion unit. At the same time, it supports modular customization of the entire system functions to adapt to application needs with different budgets.

[0047] The mobile safety interlock unit uses non-contact Hall displacement sensors mounted on the moving wheels and high-precision tilt sensors on the support bracket to collect real-time data on the device's position and placement status. It also incorporates a dual anti-shake and anti-accidental-touch mechanism: firstly, it adds a delay filter, delaying the execution of the operation loop interlock logic by 0.5 seconds after the displacement sensor triggers, filtering out instantaneous trigger signals caused by slight device vibrations; secondly, it employs a hysteresis comparison algorithm, setting the tilt trigger threshold to: triggering the safety interlock when the device tilt angle > 3.5°, and releasing the interlock only when the device returns to a tilt angle < 2.5°, avoiding frequent interlocking and unlocking caused by signal jitter at the threshold edge. When the device is detected to be in continuous movement, or the device's tilt angle > 3.5°, or the gas extinguishing device is not fully bolted, the safety interlock mechanism is immediately triggered, locking all analog operation loops and high-voltage power supply loops, retaining only standby power to prevent safety hazards and equipment damage caused by accidental triggering during movement. Only when the device is detected to be fixed in place, horizontally positioned, and the gas extinguishing device bolts are secured, is the system's full operation privilege unlocked.

[0048] The intelligent power supply management unit monitors the main power supply's power level, output voltage, and current status in real time. When it detects undervoltage, overcurrent, or short-circuit faults, it immediately cuts off the power supply to the corresponding faulty circuit and triggers an audible and visual alarm. It also has a built-in dual power supply redundancy switching function, which allows for seamless switching to the backup power supply when the main power supply fails, ensuring uninterrupted training. At the same time, it synchronizes the power fault information to the traceability module in step 6, enabling full-process recording of the equipment's operating status.

[0049] The hardware reliability assurance unit, designed for frequent device movement, uses industrial-grade aviation connectors for all external connectors. Internal signal and power cables are made of flexible cable used with drag chains. All internal cables are secured at multiple points with cable ties and clips to prevent cable damage and connector loosening caused by bending or pulling. It also features a built-in real-time monitoring function for cable continuity and connector contact status. When poor cable contact or signal interruption risk is detected, an early warning is triggered to prevent signal abnormalities during training.

[0050] The modular functional expansion unit, on the one hand, reserves standard industrial real I / O output module interfaces, compatible with digital and analog signal input and output, and can output control signals conforming to the real FAS system protocol to directly drive real field equipment such as smoke exhaust valves, exhaust fans, and fire pumps, achieving compatibility between pure analog simulation and semi-physical simulation modes to adapt to different levels of training needs; on the other hand, it adopts a modular and customizable architecture, dividing the system functions into a basic version (core linkage control, basic alarm simulation), an advanced version (adding fault injection, operation traceability), and a full-function version (full module functions). Users can tailor the corresponding functional modules according to their training budget and needs, and use general-purpose PLC main control units to replace customized hardware, significantly reducing system hardware costs and covering the full-scenario application needs from large subway operating companies to small training institutions.

[0051] This module addresses the issues of existing mobile training devices, such as the lack of a dedicated safety control mechanism, the susceptibility of safety interlocks to accidental triggering, insufficient cable reliability due to frequent movement, lack of hardware-in-the-loop (HIL) compatibility, and uncontrollable costs. It ensures the safe and stable operation of the device across all scenarios while significantly improving the system's adaptability and cost-effectiveness.

[0052] In summary, the control system in this embodiment constructs a complete closed-loop control system for subway FAS and gas extinguishing system simulation training through sequentially linked functional modules. Firstly, the signal acquisition and processing module achieves high-fidelity simulation of the real signal characteristics of different types of fire detectors. The built-in signal variation simulation unit can reproduce the non-ideal signal characteristics caused by environmental temperature, dust, and aging. Simultaneously, the open sensitivity parameter adjustment interface breaks through the limitations of existing binary state simulation and signal idealization distortion, making the training scenario more closely resemble the real operating environment and preventing a disconnect between training and on-site practice. Secondly, through the subway section dynamic mapping and zoning control module, coupled with a visual drag-and-drop configuration tool, the system realizes the subway... The dynamic topology mapping of the intervals and the coupling and linkage with adjacent intervals, while supporting custom configuration, can adapt to the subway station structures and system configurations of different cities and lines, greatly improving the versatility and applicability of the device, while reducing the system maintenance threshold; through the FAS and gas extinguishing system full logic linkage control module, with built-in full-process linkage logic conforming to national standards and subway industry specifications, a complete linkage closed loop from fire confirmation, pre-start, delay control, emergency start and stop to discharge feedback is realized, making the training content fully aligned with actual operation, solving the problem of the disconnect between existing training and practice; through the multi-dimensional fault condition injection and emergency response simulation module, adopting an atomic fault injection design, with built-in coverage of full The system's fault database includes independent clearing commands and a one-click reset mechanism for each fault. A hardware watchdog timer prevents system deadlock. Faults can be injected and cleared at any point during the training process, enabling practical and highly stable emergency response training. This comprehensively improves trainees' emergency response capabilities and fills the gap in existing technologies that cannot conduct fault emergency training or where fault injection can easily lead to training interruptions. Through a multi-device collaborative ventilation and auxiliary system linkage control module, the system achieves coordinated control of ventilation, fire pumps, access control, and broadcasting systems in fire scenarios. It fully replicates the collaborative working logic of multiple systems under subway fire conditions, making the training scenarios more comprehensive. Hierarchical access control and full-process operation are also implemented. The traceability module constructs a three-level access control system, realizing full-process, tamper-proof traceability of operational behavior. This avoids system configuration errors caused by misoperation and enables comprehensive review of the training process. Through the standardized training assessment and intelligent scoring module, a flexible multi-path scoring architecture is adopted, supporting the configuration of multiple correct handling paths. The scoring strategy of "key node must be reached and time sequence tolerance" replaces the traditional strict sequence comparison mode, which can effectively avoid misjudgment of non-standard but compliant handling methods. At the same time, a visual scoring rule configuration tool is provided to realize the quantitative evaluation and intelligent scoring of training effectiveness, solving the problems of existing training assessment relying on subjective judgment, inability to quantify effectiveness, and rigid scoring mechanisms.Through a mobile device safety interlock and power supply management module, a dual anti-shake and anti-accidental-touch safety interlock mechanism with delay filtering and hysteresis comparison is constructed to address the mobile nature of the device. It adopts industrial-grade high-reliability connectors and cable design, and simultaneously realizes intelligent power supply management and dual-power redundant switching. This eliminates safety hazards, sensor false triggering risks, and hardware reliability issues during the movement of the mobile device, while ensuring continuous and stable operation during training. It also reserves real I / O interfaces for compatibility with hardware-in-the-loop simulation and adopts a modular, customizable design to adapt to different budget requirements, significantly reducing the application threshold and cost of the system. Overall, this control system not only realizes full-scenario, full-process, and practical simulation training of subway FAS and gas fire extinguishing systems, greatly improving training quality and trainees' practical and emergency response capabilities, but also possesses strong versatility, safety, maintainability, and high cost-effectiveness.
