[0025] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present disclosure. In the following detailed description, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is apparent that one or more embodiments may also be implemented without these specific details. In addition, in the following description, descriptions of known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present disclosure.

[0026] The terms used herein are only for describing specific embodiments and are not intended to limit the present disclosure. The terms "comprise", "include", etc. used herein indicate the existence of the features, steps, operations and / or components, but do not exclude the existence or addition of one or more other features, steps, operations or components.

[0027] All terms (including technical and scientific terms) used herein have the meanings commonly understood by those skilled in the art unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0028] When using expressions such as "at least one of A, B, and C, etc.", they should generally be interpreted according to the meaning of the expression commonly understood by those skilled in the art (for example, "a system having at least one of A, B, and C" should include but is not limited to a system having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, C, etc.).

[0029] The normal operation of the brake system plays a vital role in the operation of the train, and the air compressor that provides the air source is of utmost importance. If the air compressor fails, the pressure in the main air duct will continue to decrease, resulting in serious underpressure in the vehicle and the application of brakes, which will cause the train to stop on the main line and cause delays, which will have a great impact on the operation. At the same time, when the air compressor is in an unbalanced operating state, its service life will be greatly reduced and it is easy to cause "emulsification phenomenon".

[0030] At present, the air compressor can be balanced controlled by adding hardware equipment, but the cost of adding hardware equipment is high, and the additional equipment is often limited by the actual application scenario, making it difficult to add equipment. Therefore, it is an urgent engineering and technical problem to be solved to balance the air compressor and perform health assessment without adding hardware equipment.

[0031] In view of this, an embodiment of the present disclosure provides a train air compressor control method, which controls the operation of multiple air compressors configured on the train according to a preset balance control strategy, wherein the energy consumption balance is adjusted according to the energy consumption balance index value of the air compressor, and the operating rate balance is adjusted by adjusting the operating rate of the air compressor within a preset time period to ensure that the energy consumption and operating rate of the air compressor are balanced. Combined with the balance control of the two levels of air compressor energy consumption and operating rate, the overall balance control of the air compressor is jointly achieved. This method not only improves the intelligent operation of the train air compressor, but also effectively extends the service life of the air compressor and reduces the occurrence of the "emulsification phenomenon" of the air compressor.

[0032] One aspect of the present disclosure provides a train, including multiple air compressors and a controller, wherein the controller is in electrical communication with the multiple air compressors, wherein the controller uses the above train air compressor control method to control the operation of the multiple air compressors. The communication process between the air compressor and the controller is implemented by a train control system, which is a complex integrated system involving multiple key components, generally consisting of a controller, an input and output unit, a display, a switch and other devices.

[0033] The train also includes an air supply system, such as a main air duct, an exhaust valve, a pressure indicator, etc., wherein the exhaust control of the main air duct pressure can be achieved by controlling the exhaust valve, thereby adjusting the working rate of the air compressor.

[0034] Figure 1 The schematic diagram of the train control system applied to the embodiment of the present disclosure is shown schematically. It should be noted that: Figure 1 What is shown is merely an example of a system architecture to which the embodiments of the present disclosure can be applied, in order to help those skilled in the art understand the technical content of the present disclosure, but it does not mean that the embodiments of the present disclosure cannot be used in other devices, systems, environments or scenarios.

[0035] like Figure 1 As shown, the train control system architecture 100 includes a controller 101, an input-output unit 102, a first digital output unit 102-1 and a second digital output unit 102-2.

[0036] The controller 101 is the core of the train network control system, responsible for the data transmission, control, monitoring and other functions of the whole vehicle, such as traction, braking, auxiliary power supply, monitoring and diagnosis of the EMU. Specifically, the controller 101 is responsible for the start and stop control of the air compressor of the train. The control signal sent by the controller 101 is sent to the input and output unit 102 through network communication. The first digital output unit 102-1 of the input and output unit outputs high and low levels to control the start and stop of the air compressor.

[0037] The input-output unit 102 is a key device in the train network control system and is responsible for connecting to the controller 101. The first digital output unit 102-1 of the input-output unit 102 is responsible for converting the control signal sent by the controller 101 into high and low levels to control the start and stop of the train air compressor. In addition, the exhaust valve is controlled by the second digital output unit 102-2 of the input-output unit 102 for exhaust control of the total air duct pressure.

[0038] It is worth noting that Figure 1 This is only a simple component example of a train control system related to an embodiment of the present disclosure. The system may also include components such as a display and a switch. The display serves as a human-machine interface to provide real-time train status information and a control interface for train operators. It usually includes a touch screen and a display screen to display the running status, fault information and operation instructions of the train. The switch is used in the train network system to connect various network devices, such as the controller 101, the input and output unit 102 and other subsystems, to achieve high-speed transmission and exchange of data.

[0039] Figure 2 A flow chart of a train air compressor control method according to an embodiment of the present disclosure is schematically shown.

[0040] like Figure 2 As shown, the method 200 includes operations S210 to S240.

[0041] In operation S210, the operation of multiple air compressors configured on the train is controlled according to a preset balancing control strategy.

[0042] In operation S220, based on the operating energy consumption of each of the plurality of air compressors within a preset period, an energy consumption balance index value for controlling the plurality of air compressors is determined.

[0043] In operation S230, when the energy consumption balance index value indicates that the plurality of air compressors are operated in a balanced manner, the operating rates of the plurality of air compressors within a preset period of time are determined.

[0044] In operation S240, when the operating rate of an air compressor does not meet a predetermined operating rate threshold, the operation of the plurality of air compressors is controlled according to the operating rate adjustment sub-strategy in the preset balancing control strategy.

[0045] According to an embodiment of the present disclosure, configuring an air compressor on a train includes configuring two air compressors, for example, one air compressor may be configured at the head of the train and one air compressor may be configured at the tail of the train respectively.

[0046] The balanced use of multiple air compressors has two meanings: (1) Avoid using one air compressor too much while the other one is idle. This will result in different life spans of multiple air compressors on the same train, making it inconvenient to inspect and maintain. (2) Multiple air compressors on the train have not reached a certain operating rate, so they need to be actively scheduled to work to avoid emulsification. Therefore, it is necessary to establish a balanced control strategy to achieve balanced use of multiple air compressors and improve the intelligent operation of trains.

[0047] The preset balancing control strategy is used to control the balanced operation of multiple air compressors, including an energy consumption adjustment sub-strategy and a working rate adjustment sub-strategy, wherein the energy consumption adjustment sub-strategy is used to control the balanced operation energy consumption of multiple air compressors, and the working rate adjustment sub-strategy is used to control the balanced working rates of multiple air compressors.

[0048] The preset time period can be determined based on actual train operating conditions, and there is no restriction here. For example, the preset time period can be one week, one month, or three months.

[0049] The operating energy consumption of the air compressor can be determined by the operating power and operating time of the air compressor, or by the on-site vehicle test method, which characterizes the electrical energy consumed by the air compressor during operation. Among them, the operating time of the air compressor can be optimized and the operating energy consumption of the air compressor can be adjusted.

[0050] Based on the operating energy consumption of the air compressor, the energy consumption balance index value of the air compressor can be determined to measure whether the air compressor is operating in a balanced manner. The energy consumption balance index value can be the difference in the operating energy consumption of multiple air compressors, or it can be the relationship between the operating energy consumption balance rate of multiple air compressors and a specific value. For example, the energy consumption balance index value is , where W cab1 Indicates the operating energy consumption of air compressor cab1, W cab2 Indicates the operating energy consumption of air compressor cab2. The energy consumption balance index value represents the balanced operation of multiple air compressors, including that the energy consumption balance index value meets the energy consumption balance index value threshold.

[0051] The working rate of the air compressor is an important parameter that reflects the operating conditions of the air compressor. It can reflect the working state and working efficiency of the air compressor. By adjusting the working rate reasonably, energy consumption can be reduced and the service life of the air compressor can be increased. The working rate adjustment sub-strategy includes controlling the working rate adjustment device so that the working rate and total air pressure meet the threshold value to ensure the balanced operation of multiple air compressors.

[0052] Figure 3A flow chart of a train air compressor control method according to another embodiment of the present disclosure is schematically shown.

[0053] like Figure 3 As shown, the method 300 includes operations S310 to S380.

[0054] In operation S310, the operation of multiple air compressors configured on the train is controlled according to a preset balancing control strategy.

[0055] In operation S320, based on the operating energy consumption of each of the plurality of air compressors within a preset period, an energy consumption balance index value for controlling the plurality of air compressors is determined.

[0056] In operation S330, it is determined whether the multiple air compressors are operating in a balanced manner according to the energy consumption balance index value. If the determination result is yes, operation S340 is performed; if the determination result is no, operation S350 is performed.

[0057] In operation S340 , the operating rates of the plurality of air compressors within a preset period of time are determined.

[0058] In operation S350, the energy consumption adjustment sub-strategy in the preset balancing control strategy is adjusted, and the operation of the plurality of air compressors is controlled by using the updated balancing control strategy.

[0059] In operation S360, it is determined whether the operating rate of the air compressor meets the operating rate threshold. If the determination result is yes, operation S370 is performed; if the determination result is no, operation S380 is performed.

[0060] In operation S370, the plurality of air compressors are controlled to operate normally.

[0061] In operation S380, the operation of the plurality of air compressors is controlled according to the operating rate adjustment sub-strategy in the preset balancing control strategy.

[0062] The energy consumption balance index value includes the balance control of the air compressor operation energy consumption and the balance rate. Judging whether multiple air compressors are in balanced operation according to the energy consumption balance index value includes comparing the relationship between the energy consumption balance index value and the threshold value, and then judging whether the air compressors are in balanced operation. For example, when the energy consumption balance index value is greater than the threshold value, the air compressors are not in balanced operation. Alternatively, when the energy consumption balance index value satisfies a specific relationship, the air compressors are not in balanced operation.

[0063] Whether the operating rate of the air compressor meets the operating rate threshold includes that the operating rate of the air compressor is less than the operating rate threshold. The operating rate threshold can be determined according to the actual operating conditions of the air compressor, for example, it can be 50%, 30%, etc.

[0064] When it is determined according to the energy consumption balance index value that the multiple air compressors are not operating in a balanced manner, the energy consumption adjustment sub-strategy in the preset balance control strategy is adjusted, and the updated balance control strategy is used to control the operation of the multiple air compressors.

[0065] For example, the train is equipped with two air compressors, cab1 and cab2. The energy consumption balance index value of the two air compressors is determined as W. cab1 -W cab2 =1.2, which is greater than the threshold value of 0.5, indicating that the two air compressors are not running in a balanced manner. At this time, the energy consumption adjustment sub-strategy is adjusted to make the two air compressors run in a balanced manner.

[0066] When determining that multiple air compressors are operating in a balanced manner based on the energy consumption balance index value, the operating rate parameter can be used to further determine whether the air compressors are operating in a balanced manner.

[0067] For example, the train is equipped with two air compressors, cab1 and cab2. The energy consumption balance index value of the two air compressors is determined as W. cab1 -W cab2 =0.3, which is less than the threshold of 0.5, indicating that the two air compressors are running in a balanced manner. It is determined that the operating rates of the two air compressors cab1 and cab2 are 25% and 45% respectively, and the operating rate threshold is 30%. The operating rate threshold of air compressor cab1 is less than the operating rate threshold, indicating that the air compressor does not meet the operating rate condition. It is necessary to adjust the sub-strategy according to the operating rate to adjust the operating rate of air compressor cab1. The operating rate threshold of air compressor cab2 is greater than the operating rate threshold, indicating that the air compressor meets the operating rate condition, and the air compressor maintains this operating rate and continues to operate normally.

[0068] According to the embodiments of the present disclosure, the operation of multiple air compressors configured on the train is controlled according to a preset balance control strategy, wherein the energy consumption balance is adjusted according to the energy consumption balance index value of the air compressor, and the operating rate balance is adjusted by adjusting the operating rate of the air compressor within a preset time period, so as to ensure the balance of the air compressor energy consumption and operating rate. By combining the two aspects of air compressor energy consumption and operating rate, the balanced control of the air compressor is jointly realized, and the energy consumption and operating rate of the air compressor can be balanced without adding any hardware. This method not only improves the intelligent operation of the train air compressor, but also effectively extends the service life of the air compressor, reduces the occurrence of the "emulsification phenomenon" of the air compressor, and at the same time reduces the cost of equipment replacement and improves the availability of the equipment.

[0069] According to an embodiment of the present disclosure, adjusting the energy consumption adjustment sub-strategy in the preset balancing control strategy includes: adjusting the preset operating time expected to be allocated to each of the plurality of air compressors based on a preset time period.

[0070] The energy consumption adjustment sub-strategy in the preset balancing control strategy can be adjusted based on a preset period to make the preset operating time allocated to each of the multiple air compressors the same, or it can be adjusted according to a specific proportional relationship to make the preset operating time allocated to each of the multiple air compressors the same.

[0071] For example, a train is equipped with two air compressors cab1 and cab2. In a week, cab1 runs on Monday, Wednesday, Friday and Sunday, and the running time is set to 3.5 days. Cab2 runs on Tuesday, Thursday, Saturday and Sunday, and the running time is also set to 3.5 days.

[0072] According to an embodiment of the present disclosure, based on a preset time period, by appropriately adjusting the preset operating time expected to be allocated to each of the multiple air compressors, the total energy consumption of the multiple air compressors satisfies a balanced relationship, and balanced operation of the multiple air compressors is achieved, thereby effectively extending the service life of the air compressor, reducing the cost of equipment replacement, and improving the availability of the equipment.

[0073] According to an embodiment of the present disclosure, based on the respective operating energy consumption of multiple air compressors within a preset time period, an energy consumption balance index value for controlling the multiple air compressors is determined, including: determining an energy consumption balance rate and an energy consumption difference based on the respective operating energy consumption of the multiple air compressors; determining a first energy consumption balance index value based on the energy consumption balance rate and a preset balance rate threshold; determining a second energy consumption balance index value based on the energy consumption difference and a preset energy consumption difference threshold; and obtaining an energy consumption balance index value based on the first energy consumption balance index value and the second energy consumption balance index value.

[0074] The energy consumption balance rate and energy consumption difference can both be calculated through the operating energy consumption of the air compressor, and are used to characterize the difference in operating energy consumption between multiple air compressors. If the difference in operating energy consumption is too large, it means that multiple air compressors are not operating in a balanced manner. Therefore, the first energy consumption balance index value determined based on the energy consumption balance rate or the second energy consumption balance index value determined based on the energy consumption difference can be directly used as the final energy consumption balance index value. Compared with a single index value as a judgment standard, the energy consumption balance index value obtained based on the first energy consumption balance index value and the second energy consumption balance index value has a high accuracy.

[0075] The following will describe in detail how to determine the first energy consumption balance index value and the second energy consumption balance index value. The energy consumption balance rate calculation method is shown in the following formula (1):

[0076] (1)

[0077] Among them, λ represents the energy consumption balance rate, W cab1 and W cab2 Respectively represent the operating energy consumption of the two air compressors on the train.

[0078] The preset balance rate threshold may be 0.5 or 2, which may be used to indicate whether the energy consumption of the air compressor is balanced.

[0079] The first energy consumption balance index value is determined by the energy consumption balance rate and the preset balance rate threshold value. For example, the first energy consumption balance index value can be λ-0.5 or λ-2. When λ-0.5 is less than or equal to 0 or λ-2 is greater than or equal to 0, it can be determined that the first energy consumption balance index value represents that the air compressor is not running in a balanced manner. Otherwise, it can be determined that the first energy consumption balance index value represents that the air compressor is running in a balanced manner.

[0080] The calculation method of energy consumption difference is shown in the following formula (2):

[0081] (2)

[0082] Among them, △ represents the energy consumption difference, W cab1 and W cab2 Indicates the operating energy consumption of each of the two air compressors.

[0083] The preset energy consumption difference threshold may be a value in the range of 0 to 1, which may be determined based on the actual operating conditions of the air compressor, for example, may be 0.5.

[0084] The second energy consumption balance index value can be determined by the energy consumption difference value and the preset energy consumption difference value threshold value. For example, the second energy consumption balance index value is △-0.5. When △-0.5 is greater than or equal to 0, it can be determined that the second energy consumption balance index value represents that the air compressor is not running in a balanced manner. Otherwise, it can be determined that the first energy consumption balance index value represents that the air compressor is running in a balanced manner.

[0085] When the energy consumption difference is greater than the preset energy consumption difference threshold, there are two meanings: (1) The control strategy for starting and stopping the air compressor is not good, and it needs to be optimized to control the two air compressors in a balanced manner. (2) If the start-stop control strategy is good, there may be an internal fault, and the air compressor needs to be repaired.

[0086] Based on the first energy consumption balance index value and the second energy consumption balance index value, an energy consumption balance index value is obtained, including the energy consumption balance index value obtained by weighted summing the first energy consumption balance index value and the second energy consumption balance index value according to a weight coefficient or by making a difference or a ratio between the two, and according to the relationship between the energy consumption balance index value and the energy consumption balance index threshold, it is judged whether the energy consumption of multiple air compressors is balanced during operation.

[0087] Based on the first energy consumption balance index value and the second energy consumption balance index value, an energy consumption balance index value is obtained, and when any value of the first energy consumption balance index value and the second energy consumption balance index value does not meet the energy consumption balance index threshold, it represents that the energy consumption of the air compressor is unbalanced during operation.

[0088] According to an embodiment of the present disclosure, based on the respective operating energy consumptions of multiple air compressors, an energy consumption balance rate and an energy consumption difference are determined, and by determining the energy consumption balance rate and the energy consumption difference, a first energy consumption balance index value and a second energy consumption balance index value are determined. Based on the first energy consumption balance index value and the second energy consumption balance index value, an energy consumption balance index value is determined. In this process, the indicators at the two levels of energy consumption balance rate and energy consumption difference are combined to determine the energy consumption balance index value, thereby improving the comprehensiveness and effectiveness of the energy consumption balance index value.

[0089] Figure 4 The diagram schematically shows the changing relationship between the operating time and operating energy consumption of the air compressor according to an embodiment of the present disclosure.

[0090] During the on-vehicle test phase, the installed air compressor is subjected to a start-stop test. The test is divided into the starting phase, the working phase and the ending phase. By testing the time-energy consumption curve of the three phases, the duration of the starting phase, the working phase and the ending phase is obtained ( , , ) and energy consumption values ​​at different stages ( , , ).

[0091] like Figure 4 As shown, curve 1 indicates that in the three stages of air compressor operation, its operating energy consumption can be approximated to a constant value, and the operating energy consumption of the air compressor can be determined by the average energy consumption and working time of the air compressor. Curve 2 indicates that the operating energy consumption of the air compressor changes with time in the starting and ending stages, and in the working stage, it can be approximated to a constant value, and the operating energy consumption of the air compressor can be determined by the operating energy consumption of each stage and the duration of each stage.

[0092] The following is a detailed description of the method for calculating the operating energy consumption of the air compressor based on the above two cases.

[0093] According to an embodiment of the present disclosure, the above method also includes: determining the average power of the air compressor based on the machine type of the air compressor and the rated power of the air compressor; and determining the operating energy consumption of the air compressor based on the average power and working time.

[0094] Air compressor machine types include piston air compressor, screw air compressor, centrifugal air compressor, rotor air compressor, scroll air compressor, etc. Different types of air compressors have different rated powers, that is, the factory power of the air compressor.

[0095] Based on the rated power of the air compressor, the calculation method for determining the average power of the air compressor is shown in the following formula (3):

[0096] (3)

[0097] in, Indicates the average power of the air compressor. It represents the rated power of the air compressor, and m represents the conversion coefficient between the rated power and average power of the air compressor.

[0098] The definition of working hours is shown in the following formula (4):

[0099] (4)

[0100] Among them, τ represents the working time, T1 represents the moment when the controller issues a start command to a certain air compressor, and the timing starts after the start, and T2 represents the moment when the controller issues a stop command to a certain air compressor.

[0101] And based on the average power and working time, the operating energy consumption of the air compressor is determined. The calculation method is shown in the following formula (5):

[0102] (5)

[0103] in, represents the average power of the air compressor, τ represents the working time, and W represents the operating energy consumption of the air compressor.

[0104] According to the embodiments of the present disclosure, the average power of the air compressor is determined by the machine type of the air compressor and the rated power of the air compressor, and then the operating energy consumption of the air compressor is determined according to the working time. Without adding additional hardware equipment to monitor the instrument, a simple and effective way to determine the operating energy consumption of the air compressor is provided, which simplifies the method of determining the operating energy consumption of the air compressor, thereby improving the simplicity of the air compressor balance control operation.

[0105] According to an embodiment of the present disclosure, the above method also includes: determining the operating power of the air compressor based on the machine type and mapping relationship of the air compressor, wherein the mapping relationship characterizes the correlation between the machine type and the experimental power; determining the normal operating energy consumption of the air compressor based on the operating power and the normal operating time, wherein the normal operating time is determined based on the operating time, the start-up time and the stop-operation time; and determining the operating energy consumption of the air compressor based on the start-up energy consumption, the stop energy consumption and the normal operating energy consumption, wherein the start-up energy consumption and the stop energy consumption are respectively measured by experimental methods.

[0106] Through the mapping relationship, the experimental power corresponding to a specific air compressor model can be determined. For example, the model of an air compressor is a piston air compressor P-X1. According to the mapping relationship, the experimental power of the air compressor is determined to be P ep-x1 .

[0107] Based on the machine type and mapping relationship of the air compressor, the experimental power of the air compressor is determined, and then the operating power of the air compressor is determined, as shown in the following calculation formula (6):

[0108] (6)

[0109] in, Indicates the operating power of the air compressor. It represents the experimental power of the air compressor, and n represents the conversion coefficient between the operating power and the experimental power of the air compressor.

[0110] Since the energy consumption of the air compressor during the start-up and shutdown phases is nonlinear, the values ​​measured during the test phase can be used for optimization and to calculate the operating energy consumption of the air compressor. The specific calculation method and process are as follows:

[0111] Normal operation time is determined based on the working time, startup time and shutdown time. The calculation method is shown in the following formula (7):

[0112] (7)

[0113] in, Indicates the normal operation time. Indicates working hours, Indicates the start-up time, that is, the duration of the initial stage of the air compressor start-stop test. Indicates the duration of stop operation, that is, the duration of the end phase of the air compressor start-stop test.

[0114] Based on the operating power and normal operating time, the normal operating energy consumption of the air compressor is determined. The calculation method is shown in the following formula (8):

[0115] (8)

[0116] in, Indicates the normal working energy consumption of the air compressor. Indicates the operating power of the air compressor. Indicates the normal operation time.

[0117] Based on the start-up energy consumption, stop energy consumption and normal working energy consumption, the operating energy consumption of the air compressor is determined. The calculation method is shown in the following formula (9):

[0118] (9)

[0119] in, Indicates the operating energy consumption of the air compressor. Indicates the starting energy consumption of the air compressor. Indicates the normal working energy consumption of the air compressor. Indicates the stop energy consumption of the air compressor.

[0120] In addition to the values ​​measured in the above optimization test phase, the energy consumption of the air compressor can also be roughly calculated.

[0121] Since the start-stop characteristics of air compressors of the same type are basically the same, the time values ​​and energy consumption values ​​of the starting and ending stages of each air compressor remain basically unchanged, so the energy consumption of the working stage can be used to calculate the energy consumption of the working stage. and duration of the work phase The average power of the air compressor during the entire process is roughly calculated as shown in the following formula (10):

[0122] (10)

[0123] in, Indicates the energy consumption during the working phase, Indicates the duration of the working phase. Indicates the average power of the air compressor. The energy consumption of the working stage in this calculation formula is and duration of the work phase Measured for the test.

[0124] According to the embodiment of the present disclosure, the duration of the start phase, the working phase and the end phase is measured by the start-stop test of the air compressor ( , , ) and energy consumption values ​​at different stages ( , , ), and the operating energy consumption of the air compressor is calculated by the above parameters. Without adding additional hardware equipment to monitor the instrument, an accurate and effective way to determine the operating energy consumption of the air compressor is provided, which reduces the equipment cost of determining the operating energy consumption of the air compressor, making the air compressor balance control operation simpler and less costly.

[0125] According to an embodiment of the present disclosure, when the energy consumption balance index value represents the balanced operation of multiple air compressors, the operating rates of the multiple air compressors within a preset time period are determined, including: determining the operating rate of the air compressor based on the allocated operating time of the air compressor and the working time of the air compressor.

[0126] The operating time allocation of the air compressor can be determined according to the actual application scenario, for example, it can be 1 hour, 2 hours, etc.

[0127] The working time of the air compressor is the working time of the air compressor during the period of time after the air compressor starts to run according to the running allocation time. The time difference is calculated in minutes.

[0128] Based on the operation allocation time of the air compressor and the working time of the air compressor, the calculation method for determining the working rate of the air compressor is shown in the following formula (11):

[0129] (11)

[0130] in, Indicates the working rate of the air compressor. Indicates the working time of the air compressor. Indicates the allocated running time of the air compressor.

[0131] For example, the time when the air compressor is started for the first time after the train is powered on is T1, the running time of the air compressor is 1 hour, and the time 1 hour after T1 is T2. The working time of the main air compressor between T2 and T1 is T3, then the working rate of the air compressor at this time is =T3*100%. After Y minutes, the current time is T4. At this time, the air compressor operating rate from time T4 to time T1 is =(working time of air compressor from T4 to T1) / (T4-T1)*100%. Y minutes can be set on the display interface, and its value range can be 10-60 minutes.

[0132] According to an embodiment of the present disclosure, by determining the operation allocation time of the air compressor and the working time of the air compressor, the working rate of the air compressor is calculated for subsequent adjustment of the working rate, reducing the occurrence of "emulsification phenomenon" and improving the intelligent application of the air compressor.

[0133] According to an embodiment of the present disclosure, the operation of multiple air compressors is controlled in accordance with the operating rate adjustment sub-strategy in the preset balancing control strategy, including: determining the total air pressure in the main air duct, wherein the main air duct is connected to the air compressor, and the air compressor is used to supply air to the main air duct; based on the operating rate, the total air pressure and the operating adjustment sub-strategy, the opening and closing of the exhaust valve is controlled, wherein the exhaust valve is used to control the air in the main air duct to be transmitted or cut off to the exhaust branch.

[0134] According to the work rate adjustment sub-strategy, the exhaust valve is controlled to achieve exhaust control of the total air duct pressure, thereby adjusting the work rate. The work rate adjustment sub-strategy includes activating and deactivating the solenoid valve in the work rate adjustment device, and also includes adjusting the activation time of the solenoid valve in the work rate adjustment device so that the work rate and the total air pressure meet the threshold. The specific adjustment method is shown as follows:

[0135] After the working rate of the air compressor is calculated according to the above formula (11), if the working rate is lower than 30% and the total air pressure is ≥ K1, the central control unit continuously activates the solenoid valve in the working rate adjustment device through the digital output unit. When the total air pressure is lower than K1, the central control unit closes the solenoid valve of the working rate adjustment device through the digital output unit; if the working rate is higher than 30%, the solenoid valve of the working rate adjustment device is closed.

[0136] Among them, the total air pressure K1 can be set on the display interface, and the setting value range can be 730-900. In addition, the air compressor working rate adjustment button can also be set on the display interface, and this button can be used to turn off this function.

[0137] The exhaust control function of the solenoid valve of the air compressor operating rate adjustment device is turned off during specific time periods every day. For example, between 7:00 and 9:00 in the morning, between 17:00 and 19:00 in the afternoon, and during train sleep, the solenoid valve control function is turned off, the solenoid valve is closed, and the air compressor operating rate is not calculated.

[0138] According to the embodiments of the present disclosure, based on the operating rate, total air pressure and operating rate adjustment sub-strategy, the relationship between the operating rate and total air pressure and the threshold is compared, and then the opening and closing of the exhaust valve is controlled to further realize the adjustment of the operating rate, ensure the operating rate of the air compressor during operation is balanced, reduce the occurrence of "emulsification phenomenon", and improve the intelligent application of the air compressor.

[0139] According to an embodiment of the present disclosure, when the energy consumption balance index represents that multiple air compressors are not operating in a balanced manner, the train health index value is updated based on the first energy consumption balance index value and the second energy consumption balance index value to obtain an updated train health index value; and based on the updated train health index value, the train maintenance assessment result is determined.

[0140] According to the different operating conditions of the train air compressor, the fault levels are divided into four levels: warning, minor fault (level three), moderate fault (level two), and serious fault (level one).

[0141] The health of the air compressor can be evaluated based on the health index value. The health index value includes basic health and real-time health, which can be determined by the number of minor faults, the number of warnings, the number of medium faults, the number of serious faults, the number of historical faults and the corresponding values ​​of the fault level.

[0142] When the balance rate does not meet the preset balance rate threshold, that is, λ≤0.5 or λ≥2, it indicates that a minor fault of "severe imbalance in air compressor energy consumption" has occurred. At this time, the maintenance personnel should be prompted to inspect the air compressor of the vehicle on the same day. The number of occurrences of such minor faults is represented by b, which represents the minor fault variable. When a minor fault occurs once, the value of b is accumulated by 1.

[0143] When the energy consumption difference is greater than the preset energy consumption difference threshold, it indicates that an "unbalanced air compressor energy consumption" warning occurs. The number of occurrences of such warnings is represented by a, which represents the warning variable. When the warning occurs once, the value of a is accumulated by 1.

[0144] If one of the multiple air compressors fails to work normally after receiving the start command, it means that a medium fault has occurred. The number of occurrences of such medium faults is represented by c, which represents the medium fault variable. When a medium fault occurs once, c is accumulated by 1.

[0145] If multiple air compressors fail to work normally after receiving the start command, it means that a serious fault has occurred. The number of occurrences of such serious faults is represented by d, which represents the serious fault variable. When a serious fault occurs once, the value of d is accumulated by 1.

[0146] The calculation method of basic health is shown in the following formula (12) and formula (13):

[0147] HB=100-x (12)

[0148] (13)

[0149] Among them, x is the number of historical failures of the system, and HB represents the basic health.

[0150] The calculation method of real-time health is shown in the following formula (14):

[0151] HR = HB-y1*a-y2*b-y3*c-y4*d (14)

[0152] Among them, HR represents real-time health, a represents the number of warnings, b represents the number of minor faults, c represents the number of medium faults, and d represents the number of serious faults. y1 is the score deducted when a warning occurs, y2 is the score deducted when a minor fault occurs, y3 is the score deducted when a medium fault occurs, and y4 is the score deducted when a serious fault occurs, where y1=1, y2=2, y3=5, and y4=10.

[0153] Based on the real-time health value, the health of the air compressor is evaluated. The evaluation indicators are shown in the following table:

[0154] Table 1 is the health assessment form:

[0155]

[0156] Based on the above health assessment method, the train air compressor is assessed for health. For example, the air compressor currently has: 4 historical faults; 2 warnings, 3 minor faults, 2 medium faults, and 1 serious fault. Due to the existence of fault records in the historical resume, the basic health is deducted. The basic health of the air compressor HB=100-x=100-4 / 2=98, indicating that the air compressor currently running on the train has no faults and is in good condition. The real-time health of the air compressor HR=100-4 / 2-(2*1+3*2+2*5+1*10)=70, indicating that the air compressor currently running on the train has a serious fault and should be returned to the warehouse for maintenance.

[0157] According to an embodiment of the present disclosure, when the air compressor is not operating evenly, the health index value of the train air compressor is updated based on the multi-level energy consumption balance index value, and the health of the train is evaluated by the health index value, so as to timely discover train faults and determine the train maintenance evaluation results to ensure the safe operation of the train.
