[0002] Existing subway vehicles are all equipped with air-conditioning systems to provide passengers with a comfortable cabin temperature. The air-conditioning system is controlled by the Train Control and Management System (TCMS) through the train communication bus, interacting with the TCMS for data and control.

[0003] Existing subway vehicle air conditioning systems can regulate the temperature of the entire train using the TCMS system. These systems automatically adjust the target temperature for the entire train based on the temperature curves specified in UIC 553-2003 or BS EN 14750-1-2006, taking into account the ambient temperature outside. However, these systems fail to consider the indoor temperature of each individual carriage within the train. High passenger occupancy rates can negatively impact passenger comfort.

[0054] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0055] The core of this application is to provide a train temperature regulation method, device and medium for adjusting the temperature of each compartment according to the passenger load in each compartment while saving energy consumption.

[0056] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0057] It should be noted that the temperature control method for a train provided by the present invention is suitable for application scenarios with multiple carriages on a train or multiple carriages on a subway vehicle. The target temperature of each passenger compartment affected by the load can be obtained in real time based on the load of each carriage on the train or subway vehicle and the rated temperature of the passenger area under the UIC working mode. The target temperature can be transmitted to the air-conditioning control unit of each carriage for execution through the train communication bus.

[0058] Figure 1 A structural diagram of a control device provided by an embodiment of the present invention, such as Figure 1As shown, the control device of this embodiment can obtain required information from the train communication bus, such as load information for each car and outdoor temperature feedback from each air conditioning controller. It can then send corresponding target temperature values to the air conditioning controllers in each car via the communication bus, commanding each air conditioner to execute the desired temperature. The control device provides a human-machine interface for drivers, passengers, and maintenance personnel, allowing for manual adjustment of key parameters of the method from the outside.

[0059] Figure 2 A flow chart of a train temperature adjustment method provided by an embodiment of the present invention is shown in FIG. Figure 2 As shown, the method includes:

[0060] S11: Obtaining the current load information, empty load information and overload load information of each carriage of the train;

[0061] S12: Determine the carriage load level corresponding to each carriage according to the relationship between the current load information, the empty load information, and the overload load information;

[0062] S13: determining the rated temperature information of the train according to the relationship between the UIC standard mode and the outside air temperature information;

[0063] S14: Determine the target temperature of each compartment according to the relationship between the rated temperature information and the compartment load level corresponding to each compartment to complete the temperature adjustment.

[0064] Specifically, the current load information of each train car is obtained. It is understood that due to different train models, the train load information varies. At the same time, in order to adjust the temperature of each car, it is necessary to actually obtain the current load information of each car. Due to the different passenger capacity of each train car, depending on the activity range and functional area of each car, the actual load information generally varies depending on the passenger capacity (restaurant car, VIP car, etc.). The load information of each car is not obtained by dividing the current total load information of the train by the number of cars. Instead, the current load information of each car is actually collected.

[0065] Vehicle load refers to the external pressure exerted on pipelines by the wheels of vehicles such as cars, trains, and airplanes. It also refers to the force exerted on structures (such as highways, bridges, and tunnels) by vehicles while stationary or in motion. The Highway Bridge and Culvert Design Code specifies standardized loads for bridge design based on analysis, synthesis, and generalization of factors such as the number of axles, the distance between the front and rear axles, and axle pressure on actual vehicles.

[0066] The empty load information is the passenger load rate in the current compartment is 0, and the overload load information is the passenger load rate in the current compartment is 1. The passenger density is usually defined as 9 people / m 2 For overload.

[0067] In step S12, the corresponding carriage load level for each carriage is determined based on the relationship between the current load information, the empty load information, and the overload load information. The corresponding load level is determined based on the load information so that the load level can represent the passenger load factor of the current carriage. The passenger load factor of the current carriage can be determined based on the relationship between the current load information and the overload load information, and the carriage load level can be determined based on the mapping relationship between the passenger load factor and the empty load information. Alternatively, the corresponding carriage load level can be obtained through mathematical calculations of the current load information, the empty load information, and the overload load information. This is not limited to the present invention and can be set according to actual circumstances.

[0068] As an embodiment, determining the carriage load level corresponding to each carriage according to the relationship between the current load information, the empty load information, and the overload load information includes:

[0069] Performing difference processing on each current load information and the no-load load information to obtain first load information;

[0070] Performing difference processing on the overload load information and the no-load load information to obtain second load information;

[0071] The first load information and the second load information are processed to obtain a corresponding carriage load level.

[0072] As you can understand, load level Ln describes the passenger load level of the vehicle, and its value range is (0-1). Higher values indicate that the vehicle compartment is closer to being overloaded. Carriages with more passengers generate more heat overall. For the same passenger area rated temperature setting, the actual passenger compartment temperature in these carriages will be higher than in carriages with fewer passengers.

[0073] The first load information is obtained by subtracting the no-load load information from the current load information, and the second load information is obtained by subtracting the no-load load information from the overload load information. The ratio of the first load information divided by the second load information is used to obtain the corresponding carriage load level.

[0074] Specifically, the current load information is L curr , the empty load information is L0, the overload load information is L3, and the specific formula of the carriage load level ln is as follows:

[0075]

[0076] Where n is the vehicle number, and the value range of a single subway vehicle or train vehicle is generally 8≥n≥1.

[0077] As an embodiment, the overload load information is greater than the no-load load information, that is, L3>L0. Generally, the current load information is less than or equal to the overload load information and greater than or equal to the no-load load information.

[0078] If the current load information is not within the range from the no-load load information to the overload load information, that is, the current load information is greater than the overload load information, then the current load information needs to be set to a closer value (overload load information or no-load load information). It should be noted that if the current load information is not within the above-mentioned range, it will be greater than the overload load information and will not be less than the no-load load information.

[0079] As an embodiment, before performing difference processing on each current load information and the no-load load information to obtain the first load information, the method further includes:

[0080] When the current load information is greater than both the overload load information and the no-load load information, the overload load information is set as the current load information, and the process proceeds to the step of performing difference processing on each current load information and the no-load load information to obtain the first load information.

[0081] It can be understood that when the current load information is greater than the overload load information, the overload load information is set as the current load information, and the subsequent load evaluation method is entered to obtain the load level of the car.

[0082] When the compartment load level of each compartment is determined, its rated temperature information is determined based on the relationship between the UIC standard mode and the outside air temperature information. Figure 3 A schematic diagram of a rated temperature information curve provided by an embodiment of the present invention is shown as follows: Figure 3 As shown, since the standard stipulates that the rated temperature of the passenger area shall not be lower than 22°C, the outside air temperature is greater than the threshold, generally 19°C. When the outside air temperature information ranges from 19°C, 27°C, 35°C, and 40°C, the corresponding rated temperature information is 22°C, 24°C, 26°C, and 27.25°C. The rated temperature information can be determined based on the existing outside air temperature value and the mapping relationship under the UIC standard mode, or based on the outside air temperature value and a preset coefficient, etc., which is not limited here. It should be noted that this embodiment only focuses on temperature adjustment under the UIC cooling mode.

[0083] After obtaining the rated temperature information, the target temperature of each compartment is determined based on the relationship between the rated temperature information and the compartment load level. It is understood that after obtaining the rated temperature information, the rated temperature information is optimized and a linear fit is performed to determine the target temperature. The temperature information in each compartment is adjusted according to the obtained target temperature.

[0084] An embodiment of the present application provides a train temperature control method, comprising: obtaining current load information, empty load information, and overload load information for each train car; determining the corresponding car load level for each car based on the relationship between the current load information, empty load information, and overload load information; determining the train's rated temperature information based on the relationship between the UIC standard mode and the outside air temperature information; and determining the target temperature for each car based on the relationship between the rated temperature information and the car load level corresponding to each car to complete temperature control. This method determines the current passenger load factor of each car based on the car load level of each car, and determines the target temperature of each car based on the train's rated temperature information according to the different car load levels, thereby automatically adjusting the temperature in different cars. This avoids the existing practice of adjusting the target temperature of the entire train based solely on the outside ambient temperature, which results in the temperature in each car being the same. Furthermore, the temperature of each car is adjusted based on the passenger load factor in each car, while also saving energy.

[0085] Rated temperature information is used to guide the air conditioning system in adjusting the supply air temperature. Its value fluctuates with the outside air temperature and has no direct relationship to the number of passengers in the vehicle. Because the human body releases heat and radiates heat externally, combined with the average human radiant temperature given in the standard, at the same Tic value, after the interior temperature is stabilized, when there are a large number of passengers, the ambient temperature perceived by each passenger will be approximately 2°C higher than the Tic value, resulting in a warmer sensation. Similarly, when the number of passengers is sparse, the perceived temperature will be approximately 2°C lower than the Tic value, resulting in a cooler sensation. Poor temperature perception can easily lead to passenger complaints.

[0086] As an embodiment, determining the rated temperature information of the train based on the relationship between the UIC standard mode and the outside air temperature information includes:

[0087] Obtaining the limit rated temperature information and the current outside air temperature information in the UIC standard mode, wherein the current outside air temperature information is greater than the temperature threshold;

[0088] The setpoint temperature information is determined based on the relationship between the limit setpoint temperature information and the current vehicle exterior air temperature information.

[0089] It is understood that the limit rated temperature information in the UIC standard mode is the lower limit rated temperature information. Figure 3 The 22℃ shown in the figure is the lower limit rated temperature information for the passenger area rated temperature determined in the standard. The current outside temperature information is greater than the temperature threshold, which is Figure 3 The value displayed in the figure is 19°C. The rated temperature information is then determined based on the relationship between the limit temperature information and the current outside air temperature information. The specific formula is as follows:

[0090] Tic=22+0.25×(t out -19)=0.25tout +17.25

[0091] Among them, t out is the outside air temperature, 22°C is the lower limit rated temperature information, and 19°C is the temperature threshold.

[0092] The embodiment of the present invention provides a process for determining the rated temperature information of a train based on the relationship between the UIC standard mode and the outside air temperature information. The obtained rated temperature information serves as a reference to facilitate the subsequent determination of target temperature information.

[0093] Based on the above embodiment, the target temperature of each compartment is determined according to the relationship between the rated temperature information and the compartment load level corresponding to each compartment, including:

[0094] Get temperature adjustment factor and temperature threshold;

[0095] The load factor is obtained by multiplying the temperature adjustment factor by the carriage load level;

[0096] Rated coefficient information is obtained by multiplying the rated temperature information by the linear coefficient;

[0097] The target temperature is obtained by adding the load factor, rating factor information and temperature threshold.

[0098] Specifically, after obtaining the rated temperature information, the rated temperature information is optimized and a linear fit is performed to determine the target temperature. The load factor is obtained by multiplying the temperature adjustment factor by the vehicle load level. It is understandable that due to the cooling mode used in this application, the load factor obtained needs to be negated. The rated coefficient information is obtained by multiplying the rated temperature information by the linear coefficient. The target temperature is obtained by adding the negated load factor, the rated coefficient information, and the temperature threshold. The specific formula is as follows:

[0099] t n =-k×L n +0.55×Tic+19

[0100] Where k is the temperature adjustment factor corresponding to the load level, the temperature threshold is 19°C, and the linear coefficient is 0.55;

[0101] The value range of k is not limited in this embodiment and can be set according to actual conditions, and is generally 1-3.

[0102] The present invention provides a process for determining the target temperature for each carriage based on the relationship between rated temperature information and the corresponding carriage load level. The carriage temperature is then adjusted based on the target temperature, avoiding the existing practice of adjusting the entire train's target temperature based solely on the ambient temperature outside the train, which results in identical temperatures in each carriage. Furthermore, the temperature in each carriage is adjusted based on the passenger load factor within the carriage, saving energy.

[0103] Based on the above embodiment, taking into account the differences in subway vehicle operating environments, such as extremely cold and hot regions and environmental humidity, the method further includes:

[0104] When the outside air temperature of the train is less than or equal to the temperature threshold, the temperature adjustment factor is adjusted;

[0105] When the adjusted temperature adjustment factor is within the preset range, returning to the step of obtaining the temperature adjustment factor and the temperature threshold;

[0106] When the adjusted temperature adjustment factor is not within the preset range, a prompt message is output, and the temperature adjustment factor before adjustment is used as the final temperature adjustment factor, and the process returns to the step of obtaining the temperature adjustment factor and the temperature threshold.

[0107] It can be understood that when the outside air temperature information of the train is less than or equal to the temperature threshold, the temperature adjustment factor k is adjusted. When the adjusted temperature adjustment factor is within the preset range, the corresponding target temperature can be obtained based on the adjusted k. If it is not within the preset range, a prompt message is output and the default value (that is, the temperature adjustment factor before adjustment) is selected to obtain the corresponding target temperature.

[0108] In other words, a manual intervention interface is provided to the user, allowing them to adjust the control method based on specific usage conditions. The adjustable parameter is k, and its value represents the effect of the load level on temperature regulation. A larger k value indicates a greater impact of different load levels on the target passenger compartment temperature. If the user-entered k is outside the permitted range, the human-computer interface will display a warning message and continue to execute according to the default value.

Figure 10-12 As shown, the first broken line from top to bottom is the target temperature straight line, the second broken line is the rated temperature broken line, the passenger compartment external temperature is used as the dependent variable, and the typical load level L n Value (0, 0.5, 1), as the external temperature t out (t out ≥19℃) changes, the load level is low, that is, L n When the value is small, the present invention n The value of t out At higher load levels, t n In most of the out The temperature is lower than Tic, which also achieves the purpose of energy saving when no-load and improving comfort when heavy-load.

[0131] This embodiment fully considers the impact of vehicle occupancy on passenger perceived temperature. When the passenger load is low and the average radiant temperature is low, the passenger compartment temperature is adjusted to a higher, comfortable temperature, ensuring passengers feel comfortable and reducing train energy consumption. When the passenger load is high and the average radiant temperature is high, the target passenger compartment temperature is appropriately lowered to ensure passengers feel comfortable and mitigate the effects of radiant temperature in crowded conditions.

[0132] The present invention reduces the need for drivers and passengers to manually intervene in the temperature of the entire vehicle, and is particularly effective in the use of unmanned fully automatic driving vehicles.
