Description

Technical Field

[0001] The present invention relates to the field of rail transit, and particularly to a control method and system for a fireproof partition door of a rail vehicle, and a rail vehicle. Background Art

[0002] According to the requirements of the EU EN 45545 fire protection standard, for subway vehicles on urban rail transit lines meeting the OC3 operation fire protection level, fireproof partition structures such as fireproof partition doors must be provided at positions not exceeding 30 m to prevent the spread of fire during a fire, causing unnecessary personal injuries and property damages. When a fire hazard occurs in a passenger-carrying carriage, the fireproof partition door provided at the end of the carriage should be closed to isolate the fire hazard in the fire carriage, prevent the fire from spreading to adjacent carriages, and open the side door of the safe carriage when the vehicle runs to the station in the shortest time, so as to achieve the purpose of protecting passengers.

[0003] Currently, the control method for the fireproof partition door of rail transit is as follows: when the train identifies a fire hazard in a passenger-carrying carriage, the fireproof partition doors provided at both ends of the carriage are automatically closed, and the passengers in this carriage need to manually open the fireproof partition door to go to the adjacent safe carriage. Since the above method requires manually opening the fireproof partition door for escape, it seriously affects the evacuation speed of the crowd. Summary of the Invention

[0004] The present invention provides a control method and system for a fireproof partition door of a rail vehicle, and a rail vehicle, so as to solve the technical problem that the existing control method for the fireproof partition door of rail transit requires manually opening the fireproof partition door for escape, which seriously affects the evacuation speed of the crowd.

[0005] To achieve the above object, the present invention adopts the following technical solutions.

[0006] On the one hand, a control method for a fireproof partition door of a rail vehicle is provided, including the following steps:

[0007] S1. When a fire is detected on the train, judge the current position of the train;

[0008] If the train is parked at a platform or in a depot, close all fireproof partition doors;

[0009] If the train is in motion, proceed to the next step;

[0010] S2. Identify the position where the fire occurs;

[0011] If the position where the fire occurs is at one end of the carriage, close the partition door at this end of the carriage, and when the passenger density p in the carriage is equal to zero, or 0 < p ≤ p1 and a fire is detected at the other end of the carriage, close the partition door at the other end of the carriage;

[0012] If the fire occurs in the middle of the carriage, the partition doors at both ends of the carriage are closed when the passenger density p in the carriage is equal to zero, and the partition door at the corresponding end of the carriage is closed when 0 < p ≤ p1 and a fire is detected at the end of the carriage;

[0013] Among them, p1 is the passenger density threshold.

[0014] The present invention determines the closing position and the number of closed partition doors by comprehensively considering the train position, the fire occurrence position, and the passenger density in the carriage, which can not only effectively control the fire but also improve the crowd evacuation speed.

[0015] In some embodiments, a fire is detected when the temperature or smoke concentration in the carriage exceeds a set threshold.

[0016] In some embodiments, when a partition door at one end of the carriage is closed, a voice prompt is given to the passengers to go to the adjacent carriage from the other end; when the partition doors at both ends of the vehicle are closed and the passenger density in the carriage is greater than zero, a voice prompt is given to the passengers to manually open the partition door and go to the adjacent carriage.

[0023] If the train is parked at a platform or in a depot, all fireproof partition doors are closed;

[0024] If the train is in motion, the fire occurrence position is further identified according to the position of the fire monitoring unit that sends the fire signal; if the fire occurs at one end of the carriage, the partition door at that end of the carriage is closed, and the partition door at the other end of the carriage is closed when the passenger density p in the carriage is equal to zero, or 0 < p ≤ p1 and a fire is detected at the other end of the carriage; if the fire occurs in the middle of the carriage, the partition doors at both ends of the carriage are closed when the passenger density p in the carriage is equal to zero, and the partition door at the corresponding end of the carriage is closed when 0 < p ≤ p1 and a fire is detected at the end of the carriage;

[0025] Among them, p1 is the passenger density threshold.

[0026] In some embodiments, the fire monitoring unit sends a fire signal when the temperature or smoke concentration inside the vehicle exceeds a set threshold.

Attached Figure Description

[0033] Figure 1 This is a flowchart illustrating a method for controlling fireproof partition doors on rail vehicles according to an embodiment of the present invention. Detailed Implementation

[0034] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0035] Example 1

[0036] See Figure 1 A method for controlling fireproof partition doors on rail vehicles includes the following steps:

[0037] S1. When a fire is detected on the train, determine the train's current location;

[0038] If the train is stopped at the platform or in the depot, all fireproof partition doors shall be closed.

[0039] If the train is in motion, proceed to the next step;

[0040] S2. Identify the location of the fire;

[0041] If the fire occurs at one end of the carriage, close the partition door at that end of the carriage, and when the passenger density p in the carriage is equal to zero, or 0 < p ≤ 1 and a fire is detected at the other end of the carriage, close the partition door at the other end of the carriage;

[0042] If the fire occurs in the middle of the carriage, close the partition doors at both ends of the carriage when the passenger density p in the carriage is equal to zero, and close the corresponding partition door at the end of the carriage when 0 < p ≤ 1 and a fire is detected at the end of the carriage.

[0043] Among them, a fire is detected when the temperature or smoke concentration in the carriage exceeds the set threshold. As Figure 1 shown, the number of people is n, the area of the carriage is s (m 2 ), and the passenger density p = n / s (persons / m 2 ), the temperature is i (°C), and the smoke concentration is j (dB / m). The temperature threshold can be set to 80 °C, and the smoke concentration threshold can be set to 0.5 dB / m.

[0044] Preferably, when the partition door at one end of the carriage is closed, a voice prompt is given to the passengers to go to the adjacent carriage from the other end; when the partition doors at both ends of the vehicle are closed and the passenger density in the carriage is greater than zero, a voice prompt is given to the passengers to manually open the partition door and go to the adjacent carriage.

[0045] Embodiment 2

[0046] A fireproof partition door control system for a rail vehicle, comprising:

[0047] An on-vehicle positioning system for obtaining the train position;

[0048] A passenger density detection unit for obtaining the passenger density in the carriage;

[0049] A fire monitoring unit, distributed in the middle and at both ends of each carriage, configured to send a fire signal when a fire is detected;

[0050] Partition doors, distributed at both ends of each carriage;

[0051] A loudspeaker; and

[0052] A control unit, configured to judge the current position of the train when receiving the fire signal;

[0053] If the train is parked at a platform or in a depot, close all fireproof partition doors;

[0054] If the train is in motion, the location of the fire occurrence is further identified based on the position of the fire monitoring unit that sends the fire signal; if the fire occurrence location is at one end of the carriage, the partition door at that end of the carriage is closed, and when the passenger density p in the carriage is equal to zero, or 0 < p ≤ 1 and a fire is detected at the other end of the carriage, the partition door at the other end of the carriage is closed; if the fire occurrence location is in the middle of the carriage, the partition doors at both ends of the carriage are closed when the passenger density p in the carriage is equal to zero, and the partition door at the corresponding end of the carriage is closed when 0 < p ≤ 1 and a fire is detected at the end of the carriage.

[0055] Preferably, the control unit is further configured to control the speaker to prompt passengers to go to the adjacent carriage from the other end when the partition door at one end of the carriage is closed; when the partition doors at both ends of the vehicle are closed and the passenger density in the carriage is greater than zero, control the speaker to prompt passengers to manually open the partition door to go to the adjacent carriage.

[0056] Among them, the fire monitoring unit sends a fire signal when the temperature or smoke concentration in the carriage exceeds the set threshold.

[0057] It should be noted that the above hardware devices are all devices already configured on existing trains. At present, several cameras, speakers and fire monitoring units are reasonably equipped at the ends and in the middle of each carriage of rail transit vehicles. The cameras can identify the number of people in the carriage through AI technology, and the passenger density in the carriage can be obtained by combining the carriage area (fixed parameter). The speakers can be triggered automatically or manually, and the fire monitoring unit can set appropriate thresholds. When the temperature or smoke concentration reaches a certain threshold, the fire monitoring unit sends a fire signal to the control unit and gives an alarm. For example, the temperature threshold can be set to 80 °C, and the smoke concentration threshold can be set to 0.5 dB / m. The existing train control unit can also automatically close the partition door when the fire monitoring unit detects a fire hazard in the carriage. The present invention only improves the closing logic of the partition door, and the implementation of other functions is all prior art.

[0058] For example, when the fire monitoring unit identifies a fire, it is automatically triggered, and at this time, the on-vehicle positioning system identifies the train position:

[0059] Assume that the train position is not at the platform. At this time, the closing strategy of the fireproof partition door needs to consider the passenger density and relevant data of the carriage environment.

[0060] After the train triggers a fire alarm, assume that the fire alarm trigger position is in the middle of the carriage. At this time, the speaker in the carriage broadcasts to remind passengers to go to the adjacent carriage.

[0061] The camera in this carriage identifies 100 passengers through AI, the carriage area is 75㎡, and the passenger density is 1.3. At this time, the fireproof partition doors at both ends of this carriage are not closed.

[0062] Thirty seconds later, the camera identified 10 passengers, with a passenger density of 0.13. The fire detection device at one end of the carriage detected a smoke concentration of 0.9 dB / m³, and the fireproof partition door at that end closed. At this time, the loudspeaker in the carriage broadcasted an announcement reminding passengers to go to the adjacent carriage from the other end.

[0063] Twenty seconds later, the camera identified one passenger, with a passenger density of 0.013, and the fire detection device at the other end detected a temperature of 90℃. At this time, the fireproof partition door at the other end automatically closed, and the loudspeaker in the carriage broadcasted a reminder to the remaining passengers to manually open the partition door and go to the adjacent carriage.
