[0036] To enable those skilled in the art to better understand this solution, the technical solutions in the embodiments of this solution will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this solution, not all of them. Based on the embodiments of this solution, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this solution.

[0037] The term "comprising" and any other variations thereof in the specification, claims, and accompanying drawings of this invention mean "including but not limited to," and are intended to cover a non-exclusive inclusion, not limited to the examples listed herein. Furthermore, the terms "first" and "second," etc., are used to distinguish different objects, not to describe a specific order.

[0038] The implementation of this disclosure will be described in detail below with reference to the specific accompanying drawings:

[0039] Figure 1 This is a schematic diagram of a subway fire safety monitoring system provided in an embodiment of this disclosure. (Refer to...) Figure 1 The monitoring system for subway fire safety includes: a pulse generation module 101, a switch module 102, a fire monitoring module 103, a gas monitoring module 104, a signal feedback module 105, and a control module 106.

[0040] The control terminal of the switch module 102 is connected to the pulse generator module 101, the first terminal of the switch module 102 is connected to the power supply, the second terminal of the switch module 102 is connected to the power supply terminal of the fire monitoring module 103, and the third terminal of the switch module 102 is connected to the power supply terminal of the gas monitoring module 104.

[0041] The first end of the fire monitoring module 103 and the first end of the gas monitoring module 104 are both connected to the first end of the signal feedback module 105, and the second end of the fire monitoring module 103 and the second end of the gas monitoring module 104 are both connected to the control module 106.

[0042] The second end of the signal feedback module 105 is connected to the control module 106;

[0043] The pulse generation module 101 is configured to generate pulse control signals;

[0044] Fire monitoring module 103 is configured to monitor subway fire signals;

[0045] The signal feedback module 105 is configured to monitor the operating status of the fire monitoring module 103 and the gas monitoring module 104.

[0046] In this embodiment, the pulse generation module 101 is configured to generate pulse signals, which can serve as driving commands for the switching module 102 to control its switching. The pulse signals can activate or adjust the operating state of the switching module 102 in an orderly manner according to preset logic and time intervals, thereby achieving energy saving, efficiency improvement, and precise control.

[0047] The switch module 102 is configured to precisely supply power to the fire monitoring module 103 and the gas monitoring module 104 according to the instructions transmitted from the pulse generation module 101. Since the switch module 102 is connected to a power supply, the fire monitoring module 103 and the gas monitoring module 104 can share a single power supply. The switch module 102 can orderly switch the power supply to the fire monitoring module 103 and the gas monitoring module 104 according to the pulse signal from the pulse generation module 101. This ensures timely power supply and extends module lifespan and reduces unnecessary energy consumption through reasonable on / off control.

[0048] For example, the low-level pulse signal and the high-level pulse signal of the pulse generation module 101 can be switched once every 30 minutes, and the low-level pulse signal can power the gas monitoring module 104, while the high-level pulse signal can power the fire monitoring module 103.

[0049] The fire monitoring module 103 is configured to monitor various fire signals in the subway environment. It can integrate smoke sensors, temperature sensors and infrared flame detectors to monitor smoke concentration, temperature changes and open flame light radiation, and convert this information into electrical signals, which are then transmitted to the control module 106 for analysis and processing. Based on preset logic, the control module 103 determines whether a fire has occurred.

[0050] The gas monitoring module 104 is configured to monitor the concentration of harmful gases in the subway environment, especially carbon monoxide, carbon dioxide, and combustible gases generated in the early stages of a fire or in scenarios with potential fire hazards. This provides auxiliary information for fire assessment while ensuring passenger respiratory safety. As a relatively enclosed space, the subway is prone to situations where the spread of harmful gases can exceed the spread of the fire itself. By monitoring the composition and concentration of gases in real time, potential fire risks (such as combustible gas leaks caused by electrical equipment failures) can be detected in advance, and the system can provide a basis for emergency measures such as ventilation and smoke extraction after a fire has occurred.

[0051] The signal feedback module 105 is configured to monitor the operating status of the fire monitoring module 103 and the gas monitoring module 104, and is used to monitor whether the two modules are working properly to ensure the reliability of this disclosure. The signal feedback module 105 can use components such as voltage divider resistors to monitor whether the fire monitoring module 103 and the gas monitoring module 104 are in a normal working state. Simultaneously, it sends the monitoring signal to the control module 106.

[0052] The control module 106 is configured to receive and process various information from the fire monitoring module 103, the gas monitoring module 104, and the signal feedback module 105. It can not only determine whether a fire has occurred based on the signals from the fire monitoring module 103 or the gas monitoring module 104, but also determine whether the fire monitoring module 103 or the gas monitoring module 104 is functioning properly based on the signal feedback module 105. Therefore, this disclosure, through the cooperation of the pulse generation module 101 and the switch module 102, achieves precise power supply control for the fire monitoring module 103 and the gas monitoring module 104. This not only ensures timely power supply but also extends the module lifespan through reasonable on / off control, effectively reducing unnecessary energy consumption and achieving energy saving and efficiency improvement. Secondly, the fire monitoring module 103 can monitor fire signals in the subway environment, improving the accuracy and reliability of fire monitoring. Simultaneously, the real-time monitoring of harmful gas concentrations by the gas monitoring module 104 provides auxiliary information for fire judgment, helping to detect potential fire risks in advance and ensuring passenger safety. Finally, the signal feedback module 105 monitors the operating status of the fire monitoring module 103 and the gas monitoring module 104, ensuring the reliability of the entire monitoring system. Therefore, this disclosure can solve the problem of insufficient timeliness in emergency response.

[0053] In one embodiment of this disclosure, reference is made to Figure 2 The switching module 102 includes a resistor R1, a transistor Q1, and a relay K1;

[0054] The base of transistor Q1 is connected to pulse generation module 101 through resistor R1, the collector of transistor Q1 is connected to the first input terminal of relay K1, and the emitter of transistor Q1 is grounded.

[0055] The second input terminal of relay K1 is connected to power supply VCC, the common terminal of relay K1 is connected to power supply VCC, the normally open terminal of relay K1 is connected to the power supply terminal of fire monitoring module 103, and the normally closed terminal of relay K1 is connected to the power supply terminal of gas monitoring module 104.

[0056] In this embodiment, resistor R1 can be used for current limiting. When the pulse generation module 101 generates a pulse signal, if this signal is directly connected to the base of transistor Q1, the transistor may be damaged due to excessive current. Resistor R1 can limit the amount of current flowing into the base of the transistor, keeping it within the safe operating range that the transistor can withstand, and ensuring that subsequent circuit components are not damaged by instantaneous excessive current.

[0057] When the pulse signal from the pulse generation module 101 reaches the base of transistor Q1 through resistor R1, if the pulse signal is a high-level pulse, transistor Q1 will conduct, which is equivalent to forming a low-resistance path that is approximately short-circuited between the collector and emitter. At this time, the first input terminal of relay K1 connected to the collector can be connected to ground, thus providing a trigger condition for the operation of relay K1.

[0058] When transistor Q1 is turned on, its collector and emitter are approximately short-circuited, effectively grounding the first input terminal of relay K1. This creates a voltage difference between the second and first input terminals, which drives the electromagnet inside relay K1, causing the normally closed contact to open and the normally open contact to close. At this point, the power supply VCC switches from powering the gas monitoring module 104 to powering the fire monitoring module 103.

[0059] When the pulse signal is a low-level pulse, transistor Q1 is cut off. At this time, relay K1 is still connected to the normally closed terminal, and power supply VCC still supplies power to gas monitoring module 104.

[0060] As can be seen from the above, this embodiment effectively controls the power supply to the fire monitoring module 103 and the gas monitoring module 104 through the combination of resistor R1, transistor Q1, and relay K1. The signal emitted by the pulse generation module 101 is transmitted to the base of transistor Q1 via resistor R1, controlling the conduction and cutoff of transistor Q1, and thus controlling the switching state of relay K1. This embodiment not only simplifies the circuit structure and reduces costs, but also improves the flexibility and reliability of the system. By switching the normally open and normally closed terminals of relay K1, this embodiment allows for easy selection of fire monitoring or gas monitoring functions, providing convenience for the diversified applications of the safety monitoring system.

[0061] In one embodiment of this disclosure, reference is made to Figure 2 The signal feedback module 105 includes resistors R2 and R3, optocoupler U1 and resistor R4;

[0062] The first terminal of the fire monitoring module 103 and the first terminal of the gas monitoring module 104 are both connected to the first terminal of the resistor R2, and the second terminal of the resistor R2 is grounded.

[0063] The first end of resistor R2 is connected to the first input end of optocoupler U1 through resistor R3. The second input end of optocoupler U1 is grounded. The first output end of optocoupler U1 is connected to power supply VCC. The second output end of optocoupler U1 is grounded through resistor R4. The second output end of optocoupler U1 is connected to control module 106.

[0064] In this embodiment, resistor R2 acts as a voltage divider resistor, which can cooperate with optocoupler U1 to monitor the operating status of fire monitoring module 103 and gas monitoring module 104, and accurately transmit relevant information to control module 106.

[0065] Since the fire monitoring module 103 and the gas monitoring module 104 output signals of different levels to characterize their own status during operation, the voltage values ​​of these signals may be high and unstable. After resistor R2 is grounded, it forms a voltage divider network with subsequent circuit components, which can effectively reduce the voltage amplitude of the input signal and keep it within a suitable voltage range that the subsequent optocoupler U1 can accept, thus avoiding damage to components such as optocoupler U1 due to excessive voltage.

[0066] Resistor R3 is used for voltage division and works in conjunction with resistor R2 to precisely adjust the voltage of the input optocoupler U1. After the signal output by the fire monitoring module 103 or the gas monitoring module 104 is initially divided by resistor R2, resistor R3 adjusts the voltage distribution again according to its own resistance value to ensure that the voltage at the first input terminal of the input optocoupler U1 accurately matches the operating characteristics of the optocoupler U1, enabling the optocoupler U1 to stably and accurately determine the information of the input signal.

[0067] On one hand, the optocoupler U1 electrically isolates the input side (the side connecting the fire monitoring module 103 and the gas monitoring module 104) from the output side (the side connecting the control module 106). The isolation layer of the optocoupler U1 effectively blocks electromagnetic interference, ensuring that the control module 106 connected to the output side is unaffected and remains undisturbed, thus guaranteeing the stability of the entire system. On the other hand, the optocoupler U1 converts the input signal obtained after voltage division from resistors R2 and R3 into an optical signal and then restores it to an electrical signal for output to the control module 106. Specifically, when the signal output by the fire monitoring module 103 or the gas monitoring module 104 is recognized by the optocoupler U1 as being in normal working condition after voltage division, the optocoupler U1 will generate a stable high-level signal at the output and transmit it to the control module 106, indicating that everything is normal; conversely, if a fault condition is identified, the output side will output a low-level signal, allowing the control module 106 to be aware of the problem with the monitoring module in a timely manner so that it can take rapid measures, such as issuing an alarm or activating backup equipment. In this embodiment, the voltage across resistor R4 is used to determine whether the fire monitoring module 103 or the gas monitoring module 104 is working properly.

[0068] As can be seen from the above, this embodiment achieves effective feedback of the status of the fire monitoring module 103 and the gas monitoring module 104. Through the voltage division of resistors R2 and R3, the signal strength of the monitoring modules is converted into a level suitable for processing by the optocoupler U1, enhancing signal compatibility and stability. The combination of optocoupler U1 and resistor R4 can determine whether the fire monitoring module 103 or the gas monitoring module 104 is working properly and transmit the monitoring results to the control module 106, improving the reliability and safety of this embodiment.

[0069] In one embodiment of this disclosure, reference is made to Figure 2 A monitoring system for subway fire safety also includes capacitor C1 and voltage regulator VD1;

[0070] Capacitor C1 and resistor R4 are connected in parallel;

[0071] Zener diode VD1 is connected in parallel with resistor R4.

[0072] In this embodiment, capacitor C1 is used for filtering. In the subway operating environment, various types of electromagnetic interference exist, such as electromagnetic pulses generated during frequent train starts and stops, and voltage fluctuations caused by the opening and closing of numerous electrical devices within the station. These interferences can cause voltage spikes and glitches in the circuit. If not addressed, the signals transmitted to control module 106 will be inaccurate, thus affecting the entire monitoring system's judgment of the status of fire monitoring module 103 and gas monitoring module 104. When capacitor C1 is connected in parallel with resistor R4, it can absorb instantaneous voltage changes.

[0073] Zener diode VD1 is used to stabilize the voltage. When the voltage rises to the breakdown voltage of the Zener diode (e.g., set to 5.1V), the Zener diode enters a breakdown state, but the voltage across it will remain stable near the breakdown voltage value and will not continue to rise significantly with the increase of the input voltage, thus ensuring that the voltage transmitted to the control module 106 remains stable within a safe range. Even under harsh operating conditions, the signal voltage received by the control module 106 is stable and reliable, and will not cause erroneous judgments or hardware damage due to voltage runaway.

[0074] As can be seen from the above, adding capacitor C1 and Zener diode VD1 to the subway fire safety monitoring system further enhances the system's stability and safety. Capacitor C1 filters out noise interference in the circuit, ensuring the purity of signal transmission. Zener diode VD1 stabilizes the output voltage during voltage fluctuations, preventing damage to circuit components due to abnormal voltage. This embodiment effectively enhances the system's anti-interference capability and circuit protection, ensuring stable operation of the monitoring system in complex environments.

[0075] In one embodiment of this disclosure, reference is made to Figure 2 A monitoring system for subway fire safety, which also includes a smoke exhaust valve 107 and a smoke exhaust fan 108;

[0076] The smoke exhaust valve 107 is connected to the control module 106 and the smoke exhaust fan 108 respectively.

[0077] In this embodiment, the smoke exhaust valve 107 is configured to control its opening and closing according to the instructions of the control module 106. During normal subway operation, the smoke exhaust valve 107 is in the closed state to maintain normal airflow and ambient temperature and humidity in the station and tunnel, preventing a large influx of external dust and impurities, and ensuring passenger comfort. However, in the event of a fire in the subway, the control module 106 quickly makes a judgment based on information collected by the fire monitoring module 103, gas monitoring module 104, etc., and issues an opening command to the smoke exhaust valve 107. At this time, the smoke exhaust valve 107 immediately opens, providing a channel for the subsequent smoke exhaust fan 108 to discharge the dense smoke and hot air generated by the fire.

[0078] The smoke exhaust fan 108 works in close coordination with the smoke exhaust valve 107. In the event of a fire, once the smoke exhaust valve 107 is opened, it can generate a powerful suction force at high speed to quickly expel a large amount of dense smoke, toxic gases, and high-temperature air generated at the fire scene from the subway system, creating a relatively safe passage for personnel to evacuate and escape.

[0079] As can be seen from the above, this embodiment significantly enhances fire response capabilities. The smoke exhaust valve 107 opens rapidly in response to the command of the control module 106, and the smoke exhaust fan 108 efficiently removes smoke, effectively improving visibility at the fire scene, creating favorable conditions for personnel evacuation and fire rescue, greatly reducing fire hazards, improving the overall fire safety level, and ensuring the safety of subway passengers and staff.

[0080] In one embodiment of this disclosure, reference is made to Figure 2 A monitoring system for subway fire safety, further comprising a first alarm module 109 and a second alarm module 110;

[0081] Both the first alarm module 109 and the second alarm module 110 are connected to the control module 106;

[0082] The first alarm module 109 is installed in the subway area;

[0083] The second alarm module 110 is installed in the monitoring room.

[0084] In this embodiment, the first alarm module 109 and the second alarm module 110 work together with the control module 106 to ensure that personnel in the relevant areas can be notified in a timely manner when a fire occurs.

[0085] The control module 106 is used to collect and analyze various fire monitoring information. Once a fire is detected, it will send instructions to the first alarm module 109 and the second alarm module 110 to trigger the alarm action, ensuring the timeliness and accuracy of information transmission, so that the alarm signal can be issued at the first time.

[0086] The subway area includes places with high population density or fire hazards, such as station halls, platforms, tunnels, and carriages. The first alarm module 109 is used to directly alert passengers and staff. It usually takes the form of an audible and visual alarm. That is, once the alarm command is received from the control module 106, it immediately emits a strong flash and a high-decibel alarm sound.

[0087] The monitoring room is the command center for subway operations, where staff constantly monitor the operational status of various subway systems. The second alarm module 110 is installed in the monitoring room to allow staff to be informed of a fire immediately, enabling swift emergency measures such as notifying the fire department, coordinating rescue operations with personnel at various stations, and remotely controlling some fire-fighting equipment. The second alarm module 110 can use a quiet yet conspicuous warning method, such as emitting a continuous buzzing sound and displaying a prominent fire alarm message on the monitoring screen.

[0088] As can be seen from the above, this embodiment provides dual protection for fire early warning information. The first alarm module 109 is directly deployed in the subway area, enabling it to respond quickly to fire situations, issue timely alarms, and remind passengers and staff to evacuate urgently. The second alarm module 110 is located in the monitoring room, providing managers with real-time fire information to facilitate the rapid activation of emergency plans and the organization of rescue forces.

[0089] In one embodiment of this disclosure, reference is made to Figure 2 A monitoring system for subway fire safety, which also includes a fire extinguishing module 111;

[0090] Fire extinguishing module 111 is connected to control module 106.

[0091] In this embodiment, the fire extinguishing module 111 and the control module 106 work together to extinguish the fire and contain its spread when a fire occurs. The fire extinguishing module 111 can activate the fire extinguishing function according to the instructions of the control module 106. The fire extinguishing module 111 can be a water mist fire extinguisher or a gas fire extinguisher, etc. Taking a water mist fire extinguishing system as an example, after receiving the activation instruction from the control module 106, its internal water pump quickly starts, pressurizes the water in the storage tank, and delivers it to the nozzles through the pipeline network. The nozzles atomize the water into tiny particles and spray them towards the fire area.

[0092] As can be seen from the above, the fire extinguishing module 111 is connected to the control module 106, realizing immediate and automatic fire suppression. Once the system detects a fire signal, the control module 106 activates the fire extinguishing module 111, rapidly releasing the extinguishing agent to effectively contain the spread of the fire, buying valuable time for personnel evacuation and subsequent rescue, and significantly improving the subway's emergency response capability and overall safety protection level.

[0093] In one embodiment of this disclosure, reference is made to Figure 2 A monitoring system for subway fire safety, which also includes a communication module 112;

[0094] The control module 106 communicates with the terminal through the communication module 112.

[0095] In this embodiment, the communication module 112 is used to accurately and timely transmit various types of data received by the control module 106 from the subway fire safety monitoring system, such as fire monitoring data and equipment operation status data, to the terminal. At the same time, it also transmits the instructions and information sent by the terminal to the control module 106 to ensure smooth communication between the two parties.

[0096] The terminal can be a device used by subway operation management personnel or fire rescue personnel, such as a computer, mobile phone, or tablet computer. It is used to receive the operating status and fire alarm information of the subway fire safety monitoring system sent by the control module 106, so as to understand the fire safety situation in the subway in a timely manner. Management personnel can remotely view the monitoring data and equipment operation status in each station and tunnel through the terminal, promptly identify potential safety hazards, and respond quickly in the event of a fire, directing on-site rescue and evacuation work.

[0097] As can be seen from the above, this embodiment ensures real-time and efficient communication between the control module 106 and the terminal, enabling the rapid transmission of information such as fire warnings, on-site conditions, and rescue instructions to relevant personnel. This improves emergency response speed and decision-making efficiency, provides solid communication support for subway fire safety, and effectively reduces the potential risks brought by fire.

[0098] The above embodiments are only used to illustrate the technical solutions of this disclosure, and are not intended to limit it. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this disclosure.
