Description

TECHNICAL FIELD

[0001] The present application relates to the field of rail transit, and in particular to a subway vehicle environment regulation method and system. BACKGROUND

[0002] With the rapid development of urban rail transit, the subway has become the core carrier of public transportation in megacities. The travel demand of residents is upgrading from "accessibility" to "comfort", and the optimization of vehicle driving experience has become the focus of industry research and development. Although the current subway vehicle is becoming mature in terms of power and safety, there are still significant shortcomings in key comfort dimensions such as noise control, air pressure balance, and light adaptation.

[0003] Noise is the main problem. The noise during operation is affected by the failure of component sealing: the aging of the window rubber strip and the insufficient precision of the door gap, which leads to the penetration of external airflow noise and tunnel echo. The noise in the vehicle can reach 75-80dB when running at high speed, far exceeding the comfort threshold, causing passengers to have tinnitus and irritability. Air pressure fluctuation is prominent. When the train enters and exits the tunnel and meets, a transient air pressure difference is formed inside and outside the vehicle. The existing air conditioner uses fixed air volume control, lacks real-time monitoring and dynamic adjustment capability, and the air pressure difference cannot be balanced in time, which stimulates the eardrum of passengers, especially sensitive groups such as the elderly and children, and even causes ear pain. In addition, the light adaptation is generally insufficient. The existing lighting is mostly manually adjusted or fixed brightness, which cannot be dynamically adapted to the intensity of external natural light and the density of vehicle passengers: strong light direct during sunrise causes glare, and fixed low brightness at night or in underground sections causes dim light, affecting visual convenience and causing visual fatigue.

[0004] In summary, the existing scheme lacks systematization, and noise, air pressure, and light are independent of each other. The design of key components lacks targetedness. Therefore, there is an urgent need to develop a multi-dimensional collaborative optimization scheme to improve comfort and simultaneously solve key problems. SUMMARY

[0010] When the number of passengers in the subway vehicle is greater than a preset number, the overall base brightness of the subway vehicle is controlled to be increased; and when the passengers are in a preset reading state, the brightness of the head region lighting of the passengers is controlled to be increased.

[0011] Optionally, when an abnormal noise peak is detected, the sealing member pressure adjusting assembly is controlled to dynamically pressurize the sealing member of the preset sealing part while reducing the rotation speed of the air conditioner, and when a preset low-frequency wheel-rail noise is detected, the loudspeaker is controlled to emit an anti-phase sound wave, and the damping coefficient of the car body damper is increased.

[0018] Optionally, the sealing state detection assembly further comprises a pressure sensor and a temperature sensor arranged in the inflation tube.

[0019] Optionally, a memory alloy wire is embedded at the edge of the side window of the passenger compartment of the subway vehicle.

[0030] In order to make the personnel in the art better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the personnel in the art without creative labor should belong to the protection scope of the present application.

[0031] It should be noted that the terms "first", "second", and the like in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or a chronological sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0032] Figure 1 is a flow chart of a subway vehicle environment adjusting method provided by an embodiment of the present application, and the present embodiment can be applied to adjust the environment of a subway vehicle to improve the comfort of the subway vehicle. The method can be executed by a subway vehicle environment adjusting system. Referring to Figure 1 , the method comprises the following steps:

[0033] S110, collecting noise data, a change rate of air pressure difference inside and outside a vehicle cabin of the subway vehicle, and passenger state data in real time during driving of the subway vehicle.

[0034] S120, when an abnormal noise peak is detected, controlling a sealing pressure adjusting assembly to dynamically pressurize a sealing member of a preset sealing part.

[0035] Specifically, the preset sealing position can be a vehicle window and a vehicle door. The sealing member pressure adjusting assembly can include a sealing state detection assembly arranged at the preset sealing position of the vehicle body, a sealing member pressure adjusting assembly, and a sealing member.

[0036] It should be noted that the existing technology mainly relies on passive vibration and noise reduction measures. In terms of vehicle drive motor installation, the traditional rubber pad has problems such as easy aging, poor adhesion, insufficient stiffness, etc., resulting in limited vibration reduction effect and short service life. Although a composite vibration reduction mounting pad with a conical rubber layer is used to optimize the axial and radial stiffness by adjusting the cone angle and thickness of the rubber layer, or to add a damping vibrator to improve the energy consumption effect, it is still difficult to dynamically compensate for complex vibrations during vehicle operation. At the same time, track vibration reduction mainly relies on steel spring floating slab and damping fasteners, which can reduce vibration transmission but may exacerbate wheel-rail noise, and there is a limitation that vibration reduction and noise reduction targets are difficult to coordinate. When an abnormal noise peak is detected, the sealing member pressure adjusting assembly is controlled to dynamically pressurize the sealing member of the preset sealing position, which can improve the sealing and sound insulation performance of the preset sealing position and block the noise propagation path from the source. Reduce the amount of external noise such as track noise and wind noise entering the vehicle, and improve the sound environment comfort in the vehicle.

[0037] S130, when the change rate of the air pressure difference between the inside and outside of the car cabin of the subway vehicle is greater than the preset change rate, the air conditioning and door system of the subway vehicle are linked to adjust the air pressure in the subway vehicle.

[0038] Specifically, by setting the air pressure sensor of the subway vehicle air conditioning system, the air pressure change in the car cabin of the subway vehicle can be monitored in real time, so as to detect the change rate of the air pressure difference between the inside and outside of the car cabin of the subway vehicle, and provide accurate data support for air pressure adjustment. By optimizing the air conditioning control algorithm, the air pressure in the vehicle is dynamically adjusted based on the air pressure monitoring data, and the air pressure difference between the inside and outside of the vehicle is reduced, which can avoid passenger ear discomfort.

[0039] It should be noted that when the subway vehicle runs at high speed in the tunnel or meets, the air pressure fluctuation is easy to cause the passenger's ear discomfort. The prior art passively suppresses the pressure change through air-tightness design (such as continuous weld, sealing rubber strip), or relies on the air conditioning system for indirect adjustment. The emergency air release system can quickly respond when the tunnel air pressure suddenly changes, but it mainly focuses on safety protection, and lacks active regulation of passenger comfort. The dynamic air pressure balance technology is not mature, for example, the light sensing control device based on PLC cannot realize real-time monitoring and accurate adjustment of the air pressure inside and outside the vehicle. It can be understood that in the vehicle acceleration, deceleration and altitude change scenes, the air pressure sensor of the embodiment of the application monitors the air pressure difference and change rate inside and outside the cabin in real time, and the data is synchronized to the central control unit. When the change rate is greater than the preset change rate, the system cooperates with the air conditioning and door system for coordinated adjustment, which can avoid the impact of sudden air pressure change on comfort. For example, when driving at high speed (> 100km / h), according to the data of the outside air pressure sensor, the door inflation sealing pressure is automatically increased (from 0.3MPa to 0.5MPa), and the air conditioning fan speed is reduced (from 1500r / min to 1200r / min) at the same time, balancing the air flow noise and sealing performance.

[0040] S140, when it is detected that the number of passengers in the subway vehicle is greater than the preset number, the subway vehicle is controlled to increase the overall vehicle basic brightness; when it is monitored that the passenger is in a preset reading state, the head region illumination brightness of the passenger is controlled to be increased.

[0041] For example, the passenger state (such as reading, resting, standing) can be recognized by the linkage seat sensor and the camera, the passenger's head is lowered to read (for more than 1 minute), and the head region illumination brightness is automatically increased (locally increased to 700lux, color temperature 5000K, reducing visual fatigue); the passenger closes his eyes to rest (for more than 30 seconds), and the surrounding region brightness is reduced (reduced to 300lux, color temperature 3000K, reducing interference). The lighting system adjusts the brightness for special groups (such as the elderly and children), and the passenger portrait data of the ticketing system is linked to automatically increase the overall vehicle basic brightness (≥500lux) and increase the color rendering index (Ra≥90) of the column lighting in the peak period, so as to facilitate the identification of the environment and the expression of others.

[0042] It should be noted that, for the problem of car tilting in ramp driving, the prior art can detect the tilting angle through a horizontal induction module, and adjust the air spring additional air chamber to keep the car horizontal, but the system is independently operated and is not linked with other comfort parameters. In terms of the seat system, although an air spring device is used to adjust the height and balance in real time, and a sensor is integrated to collect track vibration data for maintenance, the function is single, and the intelligent dimensions such as light adjustment and passenger flow density adaptation have not been fully integrated. The camera of the subway vehicle and the seat sensor installed on the seat of the subway vehicle in the embodiment of the application can be linked to obtain the number and state of passengers in real time, and adjust the brightness according to the state and number of passengers.

[0043] The embodiment of the application improves the comfort of the subway from three aspects of noise, air pressure and illumination: dynamically pressurizing the seal member of the preset sealing part can optimize the sealing performance of the subway vehicle to reduce noise. Through linkage control of the air conditioner and the door, the air pressure difference change rate inside and outside the vehicle is reduced, and the brightness inside the vehicle is adjusted according to the number and state of passengers in the subway. Multi-dimensional cooperation can effectively improve the environment inside the vehicle and improve passenger comfort.

[0044] Optionally, on the basis of the above embodiment, when an abnormal noise peak is detected, the seal member pressure adjusting assembly is controlled to dynamically pressurize the seal member of the preset sealing part, and at the same time, the air conditioner speed is reduced, and when a preset low-frequency wheel-rail noise is detected, the loudspeaker is controlled to emit a reverse sound wave, and the vehicle body damper is linked to increase the damping coefficient.

[0045] It can be understood that, when the preset low-frequency wheel-rail noise is detected, the passenger comfort can be further improved in combination with the active noise reduction scheme.

[0046] Figure 2 is a flow chart of another subway vehicle environment adjustment method provided by the embodiment of the application. Optionally, on the basis of the above embodiment, on the basis of the above embodiment, reference is made to Figure 2 Before step S110, it further includes:

[0047] S210, a sealing system digital model is constructed, and based on the material aging curve, the number of opening and closing times and the environmental temperature input by the accelerated aging test, the remaining life of the seal member is predicted through the LSTM neural network.

[0048] It can be understood that, by constructing the sealing system digital model, based on the material aging curve, the number of opening and closing times and the environmental temperature input by the accelerated aging test, the remaining life of the seal member is predicted through the LSTM neural network, so that the seal member can be replaced "on demand" instead of "periodically".

[0049] The subway vehicle environment adjusting system provided by the embodiment of the present application comprises a sealing state detection assembly, a sealing member pressure adjusting assembly and a sealing member arranged at a preset sealing position of a vehicle body, an air pressure sensor of a subway vehicle air conditioning system, a camera in the subway vehicle, a noise detection assembly and a noise processing assembly arranged inside and outside a cabin of the subway vehicle.

[0050] The embodiment of the present application can systematically improve the comprehensive comfort of the subway vehicle and improve the travel experience of passengers by optimizing the vehicle body, the sound insulation component, the air pressure adjustment and the illumination system.

[0051] Optionally, on the basis of the above embodiment, the preset sealing position comprises a side window of a passenger compartment of the subway vehicle; the sealing state detection assembly comprises a vehicle speed sensor for detecting the running speed of the subway vehicle and a gap sensor for detecting the gap between the glass and the window frame of the subway vehicle; and the sealing member comprises a fixed frame and an inflatable tube; the fixed frame is of a door-shaped structure, and the inflatable tube comprises an inner rubber layer, a fiber reinforced layer and an outer rubber layer.

[0052] It can be understood that the side window of the passenger compartment of the embodiment of the present application adopts the sealing state detection assembly to improve the sealing property of the side window and reduce the noise of the vehicle. The inflatable tube is dynamically inflated to adapt to the gap change, so as to solve the sealing of the complex curved surface. The structure of the inflatable sealing system comprises a fixed frame and a three-layer structure inflatable tube. The fixed frame is of a door-shaped structure (three-side limiting), and the inflatable tube is composed of an inner rubber layer (butyl rubber, air preservation), a fiber reinforced layer (stretch resistance) and an outer rubber layer (chloroprene rubber, weather resistance). The inflatable sealing system is provided with a pressure closed-loop control. Through the detection data of the wind speed sensor and the gap sensor, the pressure of the inflatable tube can be dynamically adjusted. For example, when the subway vehicle runs at a speed of 120 km / h, the pressure is increased to 0.6 MPa, and when the subway vehicle stops, the pressure is decreased to 0.3 MPa, which can adapt to different working conditions. The inflatable tube can be inflated by using the air supply of the air cylinder of the subway vehicle, and is actively attached to the irregular surface of the window frame and the glass. The compression amount can be dynamically adjusted, and the profile difference of the three-dimensional curved surface can be compensated. Without relying on mechanical pre-tightening, the inflatable amount can be dynamically adjusted by the pressure sensor under the vibration working conditions such as starting and stopping of the vehicle and meeting, and the stability of the sealing property can be improved by more than 40%.

[0053] Optionally, on the basis of the above embodiment, the sealing state detection assembly further comprises a pressure sensor and a temperature sensor arranged in the inflatable tube.

[0054] Specifically, a micro pressure sensor and a temperature sensor can be implanted in the sealing rubber layer to monitor the pressure change of the sealing surface in real time. For example, when the pressure decreases by 10%, a pre-warning (indicating sealing failure) is triggered. Through intelligent monitoring and control, the sealing performance can be dynamically adjusted from "passive maintenance" to "active pre-warning".

[0055] Optionally, on the basis of the above embodiment, the side window edge of the passenger compartment of the subway vehicle is embedded with a memory alloy wire.

[0056] It can be understood that the side window edge of the passenger compartment of the subway vehicle is embedded with a shape memory alloy wire, which can compensate for the gap (up to ±2 mm) when the temperature change causes the sealing gap to expand, thereby maintaining stable sealing performance.

[0057] Optionally, on the basis of the above embodiment, the preset sealing part further comprises a door of the subway vehicle; the sealing state detection assembly comprises a door locking force sensor arranged on the door of the subway vehicle; and the sealing member comprises an inflatable rubber tube, and the sealing member pressure adjusting assembly comprises an inflatable rubber tube pressure controller.

[0058] It can be understood that the inflatable rubber tube is arranged at the periphery of the door, the door locking force sensor is linked with the inflatable rubber tube pressure controller, when uneven locking (for example, single-point force difference >100N) is detected, the inflatable pressure of the corresponding area is dynamically adjusted (for example, local pressure increase of 0.1~0.2MPa), the sealing deviation is compensated, and the uniformity of the full-circle sealing pressure can be improved to more than 90%. The door system adopts adaptive inflatable control: combined with a vehicle speed sensor (speed 0~160km) and an external wind pressure model (established by CFD simulation), the inflatable pressure is dynamically adjusted (for example, when the speed is 160km, the pressure is automatically increased to 0.7MPa, and when stopping, the pressure is decreased to 0.2MPa), which can ensure sealing while reducing rubber tube fatigue. The door system distributed sensing network is set: micro pressure sensors and fiber grating sensors are embedded in the sealing surface to monitor the sealing pressure (normal range 0.2~0.8MPa) and the lip wear in real time, and the data is transmitted wirelessly to the door control system with a delay of ≤100ms.

[0059] Optionally, on the basis of the above embodiment, the noise detection assembly comprises a micro microphone array and a vibration sensor arranged at the seat, the column, the wheel rail, the air conditioner and the door of the subway vehicle, and the noise processing assembly comprises a loudspeaker arranged below the seat of the subway vehicle.

[0060] It can be understood that active noise reduction can be achieved by using intelligent sensing and loudspeaker linkage control technology. Micro microphone arrays and vibration sensors are arranged in the vehicle (seat, column), outside the vehicle (wheel rail, air conditioner, door), which can identify the type (such as wheel rail screaming, airflow howling) and intensity (accuracy ±1dB) of the noise source in real time. When detecting 80~160Hz low-frequency wheel rail noise, the in-vehicle ANC system (loudspeaker arranged below the seat) emits an opposite sound wave, while the vehicle body damper (magnetorheological material) increases the damping coefficient (from 0.02 to 0.05) in linkage, thereby double-suppressing low-frequency vibration.

[0061] Optionally, on the basis of the above embodiment, the OLED lighting film layer is embedded in the window interlayer of the subway vehicle.

[0062] It can be understood that the OLED lighting film layer is embedded in the window interlayer, which can be used as a side window during normal driving and automatically lighted in a tunnel as auxiliary lighting (brightness uniformity ≥ 90%), and can also display simple information (such as station name, through the change of light transmittance).

[0063] In summary, the scheme of the embodiment of the present application has the following beneficial effects: significantly improving the riding comfort: through the optimization of the sealing performance of the vehicle components and the linkage sealing mode of each component, the noise in the vehicle can be reduced by 5-8dB, effectively suppressing the noise; the air pressure adjustment linkage system controls the pressure change rate inside and outside the vehicle within 0.3kPa / s, greatly reducing the discomfort of eardrum; the light sensing dynamic dimming can adapt to the ambient light and passenger flow density in real time, avoiding visual fatigue caused by glare or dimness, and improving the driving and riding experience in all directions. Realize the breakthrough of multi-system collaborative technology: break through the limitation of "single dimension optimization" of the existing technology, build a cross-field collaborative mechanism of "window sealing system-vehicle door sealing and control-air conditioning control-speaker noise reduction-illumination adjustment", solve the problem of mutual fragmentation of noise, air pressure and light adjustment in traditional schemes, and achieve the systematic optimization of comfort improvement. Strong engineering practicability and adaptability: modular design idea is adopted, and the core components (such as pressure sensor, sealing rubber strip, light sensing module) can be adapted to different types of subway vehicles, which can be used for new vehicle factory configuration and also applied to existing line vehicles through local modification, reducing the industry promotion threshold. Energy saving and operation economy: the air conditioning system dynamically adjusts the fresh air volume and operating power through intelligent algorithm, combined with the adaptive energy saving mode of the lighting system, which can reduce the energy consumption of vehicle environment control by 15%-20%; the service life of the optimized sealing components (such as weather-resistant silicone rubber strip) is extended to more than 10 years, reducing the frequency and cost of operation and maintenance, and realizing long-term economic benefits. Improve the operation safety redundancy: high air tightness of the vehicle body and the air pressure active adjustment system can quickly buffer the pressure fluctuation in the tunnel intersection, entry and exit station and other air pressure mutation scenes, reduce the safety risk in extreme working conditions; the non-glare lighting environment can improve the passenger's visual clarity and attention, indirectly reducing the risk of accidental collision in the vehicle.
