[0002] Currently, the air pressure inside subway trains during operation is set by adjusting the airflow of the air conditioning system and the exhaust system within the depot. Furthermore, the door opening / closing force is a fixed value, without considering the impact of air pressure resistance. However, the impact of the train on the tunnel causes pressure changes within the tunnel, resulting in completely different pressures inside and outside the train. The operation of the tunnel's ventilation system, the train's pressure wave protection devices, and the operation of the doors and platform screen doors cause constant pressure fluctuations within the tunnel, the train, and the platform. This can easily lead to a mismatch between the pressure difference inside and outside the train and the door opening / closing force when the train arrives at a station, affecting the door opening / closing action and often causing the doors to fail to close due to anti-pinch functionality. Additionally, changes in the train's own condition and the external environment during operation inside and outside the tunnel cause constant pressure changes inside and outside the train, affecting the sealing performance of various components, especially the doors.

[0003] Therefore, to solve the above problems, it is necessary to conduct a systematic and comprehensive analysis and consideration of the vehicle's location and status, the pressure parameters inside and outside the vehicle and inside the platform screen doors, the air conditioning fresh air and exhaust operation procedures, and the operation procedures of the vehicle doors and platform screen doors.

Attached Figure Description

[0038] To more clearly illustrate the technical solution of the present invention, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings described below are only one embodiment of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0039] Figure 1 This is a flowchart of the rail vehicle door and air conditioning control method in an embodiment of the present invention;

[0040] Figure 2 This is a structural block diagram of the vehicle door and air conditioning control device in an embodiment of the present invention. Detailed Implementation

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] The technical solutions of this application will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0043] like Figure 1As shown in the figure, the rail vehicle door and air conditioning control method provided by the embodiment of the present invention includes the following steps:

[0044] Step 1: When the vehicle arrives at the station, obtain the absolute pressure inside the vehicle. and absolute pressure outside the vehicle like Then increase the opening of the fresh air valve and close the waste air valve until... And maintain.

[0045] The rail vehicle consists of multiple cars, each equipped with at least one independent air conditioning system. At least one absolute pressure differential sensor is installed inside each car and on the corresponding exterior surface. The absolute pressure differential sensor inside the car is used to collect the absolute pressure P inside the car when the vehicle is in different states. A The absolute differential pressure sensor outside the vehicle is used to collect the absolute pressure P outside the vehicle when the vehicle is in different states. B Each car's air conditioning system controller operates the fresh air valve and exhaust valve based on the corresponding absolute pressure inside and outside the car. Alternatively, each car can have an additional control module that generates control commands based on the corresponding absolute pressure inside and outside the car. The air conditioning system controller then uses these commands to control the fresh air valve and exhaust valve. Increasing the opening of the fresh air valve increases the fresh air volume, while decreasing it decreases it. Similarly, increasing the opening of the exhaust valve increases the exhaust volume, while decreasing it decreases it.

[0046] When multiple absolute differential pressure sensors are installed inside and / or outside each car, the average value of the absolute pressure inside the car collected by the multiple absolute differential pressure sensors inside the car is taken as the absolute pressure inside the car, and the average value of the absolute pressure outside the car collected by the multiple absolute differential pressure sensors outside the car is taken as the absolute pressure outside the car.

[0047] In this embodiment, absolute differential pressure sensors are installed inside and outside the vehicle doors, and inside the platform screen doors. Vehicle status includes when the vehicle arrives at the station, after the vehicle arrives at the station and before the doors open, after the doors open, after the doors open and before the doors close, after the doors close, and when the vehicle is running.

[0048] Most rail vehicles have sliding doors. Because the door pushes horizontally first and then moves vertically when opening, this creates negative pressure inside the vehicle, making it difficult to open. Therefore, to avoid this problem, the absolute pressure inside the vehicle is increased before the door is opened. ≥ Absolute pressure outside the vehicle The horizontal direction refers to the direction perpendicular to the door and facing outwards from the passenger compartment, while the vertical direction refers to the direction parallel to the door.

[0049] Based on the absolute pressure inside the vehicle and absolute pressure outside the vehicle Adjusting the pressure difference between the inside and outside of the vehicle to achieve the desired absolute pressure inside the vehicle. ≥ Absolute pressure outside the vehicle This solved the problem of difficulty in opening the car doors caused by negative pressure.

[0050] In this embodiment, when hour, and The difference ranges from 30Pa to 50Pa to meet the positive pressure requirements inside the vehicle as specified in the standard.

[0051] Step 2: After the vehicle arrives at the station and before the doors open, obtain the absolute pressure outside the vehicle. and the absolute pressure inside the shielding door like Open the platform screen door first, then open the train door; if Open the car door first, then open the platform screen door.

[0052] At least one absolute pressure differential sensor is installed inside the platform screen doors corresponding to the interior and exterior of the vehicle. The absolute pressure differential sensor inside the platform screen door is used to collect the absolute pressure P inside the platform screen door when the vehicle is in different states. C When there are multiple absolute differential pressure sensors inside the shielding door, the average value of the absolute pressure inside the shielding door collected by the multiple absolute differential pressure sensors is taken as the corresponding absolute pressure inside the shielding door.

[0053] Based on the absolute pressure outside the vehicle and the absolute pressure inside the shielding door Control the opening sequence of the train doors and platform screen doors, so that... It was able to be maintained. When At that time, there was no requirement for the opening sequence of the train doors and platform screen doors.

[0054] Step 3: Based on the absolute pressure inside the vehicle and absolute pressure outside the vehicle Calculate the door opening force and control the door opening based on the door opening force.

[0055] Let F be the force required to open the car door under normal circumstances. CO This refers to the opening force set for the vehicle within the parking space, without considering the effect of air resistance (i.e., it is not subject to the vertical component of air resistance). When the door opens / closes, air resistance is taken into account; that is, the door experiences the vertical component of air resistance. Let the coefficient of friction for the door when considering air resistance be μ. C The formula for calculating the door opening force is:

[0056]

[0057] Among them, F C 'O To account for the door opening force when air resistance is taken into account, F CO To determine the door opening force without considering air resistance, S C Let μ be the area of ​​the car door. C To account for air resistance, the coefficient of friction of the car door is calculated. A new control module is added to each car. The control module calculates the door opening force according to equation (1), generates a control command based on the door opening force, and the door system controls the door to open according to the control command.

[0058] Based on the absolute pressure inside the vehicle and absolute pressure outside the vehicle Adjusting the door opening force to match the pressure difference between the inside and outside of the vehicle further solves the problem of difficult door opening.

[0059] Based on the absolute pressure outside the vehicle and the absolute pressure inside the shielding door Calculate the opening force of the platform screen door, and control the opening of the platform screen door based on the opening force. The formula for calculating the opening force of the platform screen door is:

[0060]

[0061] Among them, F S ' O To account for air resistance when opening the shielding door, F SO To determine the opening force of the shielding door without considering air resistance, S S For the area of ​​the shielding door, μ S The coefficient of friction of the shielding door when air resistance is taken into account.

[0062] The opening sequence of the platform screen door and the vehicle door can be determined according to step 2.

[0063] Step 4: After opening the car door, obtain the absolute pressure inside the car. and absolute pressure outside the vehicle like Then close the fresh air valve and increase the opening of the waste air valve until... And maintain.

[0064] Because the car door moves vertically first and then pulls in the opposite horizontal direction (inwards towards the passenger compartment) when closing, this creates positive pressure inside the vehicle, making it difficult to close the door. Therefore, to avoid this problem, the absolute pressure inside the vehicle is adjusted before the door closes. ≤ Absolute pressure outside the vehicle

[0065] In this embodiment, when hour, and The range of the difference is 30 Pa to 50 Pa.

[0066] Step 5: Obtain the absolute pressure outside the vehicle after the door is opened and before it is closed. and the absolute pressure inside the shielding door like Then close the platform screen doors first, then close the train doors; if Then close the car doors first, and then close the platform screen doors.

[0067] Based on the absolute pressure outside the vehicle and the absolute pressure inside the shielding door Control the closing sequence of the train doors and platform screen doors, so that... It was able to be maintained. When At that time, there was no requirement for the closing sequence of the train doors and platform screen doors.

[0068] Step 6: Based on the absolute pressure inside the vehicle and absolute pressure outside the vehicle Calculate the door closing force and control the door to close based on the calculated closing force.

[0069] In this embodiment, the formula for calculating the door closing force is:

[0070]

[0071] Among them, F C ' C To account for the door closing force when air resistance is taken into account, F CC The closing force of the car door is taken into account without considering air resistance.

[0072] Based on the absolute pressure inside the vehicle and absolute pressure outside the vehicle Adjusting the door closing force to match the pressure difference between the inside and outside of the vehicle further solves the problem of difficult door closing.

[0073] Based on the absolute pressure outside the vehicle and the absolute pressure inside the shielding door Calculate the closing force of the platform screen door, and control the closing of the platform screen door based on the closing force. The formula for calculating the closing force of the platform screen door is:

[0074]

[0075] Among them, F S ' C To account for air resistance when opening the shielding door, F SC To determine the opening force of the shielding door without considering air resistance, S S For the area of ​​the shielding door, μ S The coefficient of friction of the shielding door when air resistance is taken into account.

[0076] The closing sequence of the platform screen doors and the vehicle doors can be determined according to step 5. To avoid excessive air resistance caused by the simultaneous opening / closing of the vehicle doors and platform screen doors, the vehicle doors and platform screen doors should not be opened or closed at the same time.

[0077] Step 7: During vehicle operation, obtain the absolute pressure inside the vehicle. and absolute pressure outside the vehicle like Then increase the opening of the fresh air valve and decrease the opening of the waste air valve until... like Then reduce the opening of the fresh air valve and increase the opening of the waste air valve until...

[0078] When the pressure difference between the inside and outside of the vehicle changes, this pressure difference exerts significant pressure on the doors, causing the door gaps to widen and reducing the door's sealing effect. During vehicle operation, the absolute pressure inside the vehicle... and absolute pressure outside the vehicle Adjusting the pressure difference between the inside and outside of the vehicle can reduce the impact of this pressure difference on the doors and improve their sealing performance. Therefore, based on the absolute pressure inside the vehicle... and absolute pressure outside the vehicle Adjusting the pressure difference between the inside and outside of the vehicle solves the problem of poor sealing performance of various sealing components (especially door seals) caused by pressure changes between the inside and outside of the vehicle.

[0079] The formula for calculating the door opening force / closing force during vehicle operation is as follows:

[0080] F C '=F C +ΔP×S C ×μ C (5)

[0081] Among them, F C 'F represents the adjusted door opening / closing force during vehicle operation.' C The opening / closing force of the vehicle door is the force adjusted before vehicle operation. In existing technology, the opening / closing force of the door is set by adjusting the airflow of the air conditioning system and the exhaust gas flow within the depot; it is a fixed value. Therefore, the opening / closing force of the door remains constant during vehicle entry / exit and during vehicle operation. C When applying force to open the car door, F C =F CO When F C When the door closing force is F C =F CC When F CO =F CC At that time, F C =F CO =F CC .

[0082] During vehicle operation, maintaining a constant pressure ΔP between the inside and outside of the vehicle prevents door opening / closing malfunctions caused by mismatch between the door opening / closing force and the pressure difference between the inside and outside of the vehicle, and also prevents the sealing effect of various sealing components from being affected by pressure changes between the inside and outside of the vehicle. This invention adjusts the door opening / closing force according to the absolute pressure inside and outside the vehicle during vehicle entry / exit and operation, matching the door opening / closing force with the pressure difference between the inside and outside of the vehicle throughout the entire operation of the vehicle, thus solving the problem of door opening / closing malfunctions caused by random changes in the pressure difference between the inside and outside of the vehicle.

[0083] In this embodiment, the value of ΔP ranges from 30Pa to 50Pa to meet the positive pressure requirements inside the vehicle specified in the standard.

[0084] Axial flow fans are typically installed in subway tunnels to exhaust exhaust gases and circulate fresh air. These fans are usually installed in ventilation shafts or openings within the tunnel to discharge exhaust gases to the surface and introduce fresh air. Additionally, some subway tunnels use wall-mounted axial flow fans, installed on the tunnel walls to improve airflow efficiency. The specific location and number of axial flow fans vary depending on the subway tunnel design and actual needs. To prevent changes in external pressure on trains, the axial flow fans in the tunnel must be shut off during station arrival and door opening / closing.
