[0058] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0059] The core of this application is to provide a method, device and medium for controlling tidal seats of urban rail vehicles.

[0060] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0061] The purpose of the folding seats is to fold them up when the carriage is crowded, giving priority to the goal of transporting a large number of passengers. When the congestion in the carriage is relieved, the folding seats will be put down to provide more seats for passengers and improve passenger comfort. At the same time, the operation of subway trains adopts the form of clearing passengers at the terminal station of the line, performing the end-to-end operation and then turning back, stopping at other stations for passengers to get on and off. Considering that the seats should be folded and put down when there are no passengers in the carriage, it is necessary to evaluate the passenger flow intensity of the entire line and decide whether to operate the seats at the terminal station.

[0062] The driver observes the number of passengers on the display screen and operates manually, which is labor-intensive and relies on personal sensory judgment, and cannot be operated accurately. Especially when the vehicle adopts unmanned driving mode, there is no driver in the vehicle to operate and control the tidal seat, and the function of the tidal seat cannot be brought into play.

[0063] In order to solve the above problems, the present application provides a method for controlling tidal seats of urban rail vehicles. Figure 1 A flowchart of a method for controlling a tidal seat in a city rail vehicle is provided for an embodiment of the present application. Figure 1 As shown, including:

[0064] S11: Acquire air spring pressure data of the vehicle at each station, wherein the air spring pressure data is total pressure data of all air springs collected by air spring pressure sensors installed in the vehicle suspension system;

[0065] S12: Obtain the passenger flow intensity of the current line according to the air spring pressure data of all stations;

[0066] S13: Determine the execution action of the tidal seat of the current line according to the passenger flow intensity;

[0067] S14: When the vehicle starts at the station, a control signal of the tidal seat is sent according to the execution action to control the unfolding or folding of the tidal seat.

[0068] In step S11, the air spring pressure data of the vehicle at each station is obtained for subsequent passenger flow intensity analysis. The air spring pressure data refers to the total pressure data collected by the air spring pressure sensor installed on the vehicle suspension system. These data reflect the load condition of the vehicle at each station. The total pressure data can be specifically the accumulation or average value of the pressure values ​​of each air spring, which is used to represent the total weight of the vehicle. In this step, the air spring pressure sensor on the vehicle suspension system collects data in real time.

[0069] When the train is running, the car body is impacted by the road surface and will bump up and down. The role of the air spring is to stabilize the car body through the expansion and contraction of the airbag to provide a comfortable riding environment. Passengers getting on and off the train will also cause the air spring to deform. Therefore, an air spring pressure sensor is provided on the air spring, and the air spring pressure sensor is electrically connected to the controller. The air spring pressure sensor can detect the pressure of the air spring. This embodiment does not limit the number of air springs. It depends on the design of the train. To a certain extent, the more air springs there are, the higher the detection accuracy.

[0070] Because it is necessary to accurately reflect the load changes in the car, data collection is performed every time the vehicle arrives at a station and passengers get on and off the bus. This data represents the degree of passenger congestion from the current station to the next station.

[0071] Step S12 obtains the passenger flow intensity of the current line according to all the air spring pressure data, and estimates the passenger flow intensity of the entire line by analyzing the air spring pressure data to determine whether the seat layout needs to be adjusted. The passenger flow intensity refers to the passenger flow or passenger flow density determined according to the air spring pressure data, which is used to indicate the degree of crowding of passengers in the carriage and can be a relative value.

[0072] The air spring pressure data of each station is summarized and analyzed. The pressure data is converted into passenger flow intensity indicators using a preset algorithm or model. Passenger flow intensity indicators may include passenger density, total number of passengers, etc. Timely analysis of passenger flow intensity can provide data support for subsequent decision-making and ensure the timeliness and effectiveness of seat control strategies.

[0073] Step S13 determines the execution action of the tidal seat of the current line according to the passenger flow intensity, and the degree of passenger flow congestion determines whether the seat is unfolded or folded. The execution action refers to the seat operation determined according to the passenger flow intensity, which can be specifically "unfold" or "fold". If the passenger flow intensity is high, the seat may need to be folded to provide more standing space; if the passenger flow intensity is low, the seat may need to be unfolded to provide more seats.

[0074] The seat needs to be adjusted after the vehicle stops and the passengers are emptied, so the control signal is sent at the starting station or the terminal. At the starting station or the terminal of the vehicle, the control signal of the tidal seat is sent according to the execution action to control the unfolding or folding of the tidal seat.

[0075] In addition, since the passenger flow in different directions of the same line is also different, it is necessary to perform corresponding operations at the starting station according to the passenger flow intensity of the corresponding direction, that is, in the direction of Station A-Station B, the passenger flow intensity data obtained by the air spring pressure data of all stations in the current direction determines the tidal seat operation that needs to be performed at the starting station A. When the terminal change operation is performed at the terminal station B and the vehicle is heading to Station A, it is necessary to determine the tidal seat operation that needs to be performed at the starting station B by obtaining the passenger flow intensity data of the air spring pressure data of all stations heading from Station B to Station A. That is, step S14 at the starting station of the vehicle, according to the execution action, sends a control signal of the tidal seat to control the unfolding or folding of the tidal seat, including: at the starting station of the vehicle, according to the execution action determined by the air spring pressure data of all stations in the direction of the current starting station, sends a control signal of the tidal seat to control the unfolding or folding of the tidal seat.

[0076] The tidal seat control method for urban rail vehicles provided by the embodiment of the present application includes: obtaining the air spring pressure data of the vehicle at each station, wherein the air spring pressure data is the total pressure data of all air springs collected by the air spring pressure sensor installed in the vehicle suspension system; obtaining the passenger flow intensity of the current line according to the air spring pressure data of all stations; determining the execution action of the tidal seat of the current line according to the passenger flow intensity; at the starting station of the vehicle, sending a control signal of the tidal seat according to the execution action to control the expansion or folding of the tidal seat. The present application analyzes the passenger flow intensity of the entire line by collecting the air spring pressure data of each station to determine the tidal seat action to be executed, and performs the corresponding expansion or folding action at the terminal or starting station, which can quickly respond to passenger flow changes and adjust the seat status. Seat adjustment at the starting station or terminal of the vehicle can ensure operation when there are no passengers or fewer passengers, reducing safety risks. Provide more space for standing passengers during peak hours, and provide more seats for sitting passengers during non-peak hours, improve passenger comfort, effectively optimize the utilization of the compartment space, and improve operational efficiency and passenger experience.

[0077] According to the above embodiment, this embodiment provides a specific implementation scheme for obtaining air spring pressure data of the vehicle at each station, including:

[0078] When the vehicle stops at a station, get the door closing signal for boarding and alighting;

[0079] When all doors have completed the door closing action for boarding and disembarking passengers, the total pressure data of all air springs is obtained as the air spring pressure data of the current station.

[0080] In this embodiment, the door closing signal for boarding and alighting refers to the action signal of the door closing when the vehicle stops at a station and all passengers have completed boarding and alighting. When the vehicle stops at a station, the open and close status of the door is monitored. The door closing sensor or switch is triggered, and a door closing signal is generated, indicating that the door has been safely closed. This step ensures that data is collected immediately after the passengers board and alight, avoiding the influence of passenger flow on data accuracy during data collection.

[0081] After all doors have been closed for entry and exit, the system collects data from the air spring pressure sensors installed in the vehicle's suspension system. The collected data includes the total pressure of all air springs, which reflects the current total weight of the vehicle. This step provides a comprehensive view of the vehicle's load by summarizing the pressure readings of all air springs.

[0082] Furthermore, this embodiment provides a specific implementation scheme, which obtains the passenger flow intensity of the current line according to the air spring pressure data of all stations, including:

[0083] Determine whether the total air spring pressure data of each station exceeds the preset standard pressure data;

[0084] If the preset standard pressure data is exceeded, it is determined that the current site is overcrowded;

[0085] If the preset standard pressure data is not exceeded, it is determined that the current site is normal;

[0086] Determine whether the overcrowded station information on the current line meets the peak conditions;

[0087] If the peak condition is met, it is determined that the current line is in the peak period;

[0088] If the peak condition is not met, it is determined that the current line is in the advection period.

[0089] This embodiment can accurately determine whether the number of passengers at each station exceeds the standard load capacity of the vehicle by real-time monitoring and analysis of the air spring pressure data. This helps to quickly identify overcrowding during peak hours, wherein the preset standard pressure data can be obtained by selecting the air spring pressure data under the standard load capacity.

[0090] The air spring pressure data of each station is monitored in real time, and the monitored pressure data is compared with the preset standard pressure data. If the air spring pressure data of a station exceeds the preset standard pressure data, the system will mark the station as overcrowded. If the air spring pressure data of a station does not exceed the preset standard pressure data, the system will mark the station as normal.

[0091] Determine whether the overcrowded station information on the current line meets the peak conditions, and comprehensively evaluate the passenger flow conditions of the entire line to determine whether the seat layout of the entire line needs to be adjusted.

[0092] By counting the number and distribution of overcrowded stations within a certain period of time, and according to the preset peak conditions (such as the proportion of overcrowded stations, or the number of consecutive overcrowded stations, etc.), determine whether the current line meets the peak period. If the overcrowded station information on the current line meets the peak conditions, the system will mark the current line as the peak period, and the tidal seats need to be expanded at the starting station of the current line. If the overcrowded station information on the current line does not meet the peak conditions, the system will mark the current line as the flat period, and the tidal seats need to be folded at the starting station of the current line.

[0093] Specifically, the execution actions of determining the tidal seats of the current line according to the passenger flow intensity include:

[0094] If it is determined that the current route is in peak period, then the execution action of the tidal seat of the current route is determined to be folding of the tidal seat;

[0095] If it is determined that the current route is in the advection period, then the execution action of the tidal seat of the current route is determined to be the tidal seat deployment.

[0096] By adjusting the seat status, it can flexibly adapt to the changes in passenger flow in different time periods, achieve optimal utilization of the car space, and improve passenger comfort and safety.

[0097] According to the above embodiment, this embodiment provides a specific implementation scheme, which determines whether the overcrowded station information on the current line meets the peak condition, including:

[0098] Obtain the length of the interval between the overcrowded station and the next station as the length of the overcrowded interval corresponding to the current overcrowded station;

[0099] The total overcrowded interval length is obtained by summing the lengths of all overcrowded intervals;

[0100] Determine whether the ratio of the total overcrowded section length to the total line length exceeds a preset ratio;

[0101] If it exceeds the preset ratio, it is determined that the peak condition is met;

[0102] If the preset ratio is not exceeded, it is determined that the peak condition is not met.

[0103] This embodiment determines whether the line is in peak period by quantitatively analyzing the interval length of overcrowded stations, thereby providing a decision-making basis for the automatic control of tidal seats of urban rail vehicles.

[0104] Obtain the length of the overcrowded interval corresponding to the overcrowded station in order to calculate the total overcrowded interval length. For each station determined to be overcrowded, the system will obtain the line length between the station and the next station. This length reflects the length of the interval from the current overcrowded station to the next station, which is called the overcrowded interval length. The interval length and total line length can be obtained through the vehicle's Geographic Information System (GIS) or vehicle tracking system.

[0105] Calculate the total overcrowded interval length and summarize the interval lengths of all overcrowded stations to evaluate the overall impact of overcrowding on the entire line. The system adds up the interval lengths of all overcrowded stations to obtain the total overcrowded interval length. The numerical accumulation ensures that the impact of all overcrowded stations is taken into account.

[0106] Determine the ratio of the total overcrowded section length to the total line length, evaluate the relative importance of the overcrowding phenomenon on the entire line, and decide whether it is necessary to adopt a peak operation strategy.

[0107] The ratio of the total overcrowded section length to the entire line length determines whether the current line is in the peak period. If the ratio of the total overcrowded section length to the total line length exceeds the preset ratio (for example, 30%, 50%), the system determines that the current line meets the peak condition, indicating that the line is in the peak period. If the ratio does not exceed the preset ratio, the system determines that the current line does not meet the peak condition, indicating that the line is in the flat period. The preset ratio can be adjusted based on historical data, operating experience and passenger flow forecasts.

[0108] By quantitatively analyzing the interval length of overcrowded stations, the passenger flow conditions of the line can be judged more accurately, thereby achieving more effective passenger flow management and flexibly adjusting the seat control strategy to meet the different needs during peak and flat periods.

[0109] According to the above embodiment, this embodiment provides a specific implementation scheme, which includes: before sending a control signal of the tidal seat according to the execution action to control the unfolding or folding of the tidal seat, the following steps are further included:

[0110] Determine whether the current operation mode is fully automatic;

[0111] If yes, correspondingly, a control signal of the tidal seat is sent according to the execution action to control the unfolding or folding of the tidal seat, including:

[0112] According to the execution action, a control signal is sent to the tidal seat through the network to control the unfolding or folding of the tidal seat;

[0113] If not, correspondingly, a control signal of the tidal seat is sent according to the execution action to control the unfolding or folding of the tidal seat, including:

[0114] A prompt message is issued according to the execution action, and the prompt message is an audio-visual signal prompting the tidal seat to be unfolded or folded.

[0115] The purpose of this embodiment is to automatically control the unfolding or folding of tidal seats in urban rail vehicles to meet different passenger flow requirements. It is determined whether the vehicle is in a fully automatic operation mode and sends corresponding control signals or prompt information according to the mode.

[0116] Determine the vehicle's operating mode to determine whether the seat is automatically controlled or requires human intervention. Fully automatic operating mode usually refers to the mode in which the vehicle can complete all operations autonomously without driver intervention.

[0117] In the fully automatic operation mode, the system will automatically control the expansion or folding of the tidal seats without manual intervention. The system sends a control signal to all tidal seats through the network according to the previously determined execution action (seat expansion or folding). The control signal is transmitted through the vehicle's internal network, triggering the electric or pneumatic actuator of the seat to achieve automatic expansion or folding of the seat. This step ensures that in the fully automatic operation mode, the seat status can be adjusted quickly and accurately to adapt to changes in passenger flow. The driver's cab occupancy signal output terminal controls the network output module. If the driver's cab occupancy signal is output, the network output module stops working. If the driver's cab occupancy signal is not output, the network output module works. According to the execution action, the control signal sent by the network output module to the tidal seat controls the expansion or folding of the tidal seat.

[0118] In non-automatic operation mode, sound and light prompts are provided to inform the staff or driver to perform seat control operations. The system generates sound and light prompts based on the execution action, such as voice broadcast or flashing warning lights. The prompt information clearly indicates the operation to be performed (seat unfolding or folding) so that the staff or driver can respond in time. It ensures that in the case of manual intervention, the operator can be guided to make the correct seat adjustment through intuitive prompt information.

[0119] In the fully automatic operation mode, the seat is automatically controlled to unfold or fold, reducing the need for manual operation and improving operational efficiency. Automated control reduces the possibility of human operation errors and improves the safety of passengers and vehicles. In the non-automatic operation mode, the sound and light prompt information ensures that the operator can perform seat control operations in a timely and accurate manner, improving the flexibility and reliability of the system. Automated control reduces the need for manual intervention, reduces labor costs, and improves the operating efficiency of the vehicle.

[0120] According to the above embodiment, this embodiment provides a specific implementation scheme, which determines whether the current operation mode is fully automatic, including:

[0121] Determine whether a zero speed signal is received;

[0122] If so, determine whether the driver's cab occupancy signal is valid;

[0123] If it is valid, it is judged that the current operation mode is not fully automatic;

[0124] If invalid, it is determined that the current operation mode is fully automatic.

[0125] This embodiment determines whether a zero-speed signal is received to detect whether the vehicle is in a stationary state. By monitoring the vehicle's zero-speed sensor or other corresponding speed monitoring equipment, it is determined whether the vehicle is in a stopped state (zero-speed state). The zero-speed signal is usually issued when the vehicle is completely stopped, indicating that the vehicle is not moving.

[0126] If the system receives a zero speed signal, it indicates that the vehicle has stopped. Next, it needs to determine whether the driver's cab is occupied. Determine whether the driver's cab occupancy signal is valid. When the vehicle is stationary, further determine whether the driver is in the driver's cab. The driver's cab occupancy sensor or related safety monitoring system can determine whether the driver is in place. A valid driver's cab occupancy signal usually means that the driver is in the driver's cab, preparing or performing manual operation.

[0127] If the cab occupancy signal shows that the driver is in place, the system will determine that the current vehicle operation mode is non-automatic operation mode. In non-automatic operation mode, the vehicle may require the driver to operate or supervise, so the control of the tidal seat may require manual intervention or prompt the driver to operate. If the cab occupancy signal shows that the driver is not in place, the system will determine that the current vehicle operation mode is fully automatic operation mode. In fully automatic operation mode, the vehicle can complete all operations autonomously, including automatic control of the tidal seat.

If the driver's cab occupancy signal is output, the network output module stops working, and if the driver's cab occupancy signal is not output, the network output module works; Figure 3 As shown, if it is in the zero speed signal state, the K01 switch is closed. If the driver's cab occupancy signal is valid, it is a non-automatic operation mode, and the driver controls the expansion or folding by manually controlling the two switches of S01; if the driver's cab occupancy signal is invalid, it is a fully automatic operation mode, the K02 switch is closed, and the specific expansion or folding is controlled by the network generation module.

It should be noted that the present application describes the embodiments of the device part from two perspectives, one is based on the functional module perspective, and the other is based on the hardware perspective.
