Description

Technical Field

[0001] The present invention relates to the technical field of train air supply, and more specifically, to a train air supply control method, system, device, equipment, medium and rail vehicle. Background Art

[0002] As is well known, a train has various air-using devices. For example, an air braking system, an air suspension system, a sanding system, and a high-voltage power supply system, etc. In order to meet the air-using requirements of various air-using devices, the train uses an air compressor to supply air to each air-using device.

[0003] However, various air-using devices do not work all the time. When the vehicle running state and environment are different, the fluctuation of the total air consumption of the vehicle is very large. In the related art, the air compressor operates at a fixed frequency, so that the flow rate of the output compressed air cannot be adjusted. This results in that when the air consumption of the vehicle is small, although the working rate of the air compressor is reduced, the noise level during the operation of the air compressor is still very high.

[0004] Therefore, how to reduce the noise during the operation of the train air compressor is an urgent problem to be solved by those skilled in the art at present. Summary of the Invention

[0060] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0061] The core of the present invention is to provide a train air supply control method, which can reduce the noise generated when the air compressor of the train operates and improve the comfort of passengers. Another core of the present invention is to provide a train air supply control system, the controller of which is used to implement the above train air supply control method, which can reduce the noise generated when the air compressor of the train operates and improve the comfort of passengers. Another core of the present invention is to provide a train air supply control device, a train air supply control equipment and a computer-readable storage medium, which respectively correspond to the train air supply control method, can reduce the noise generated when the air compressor of the train operates and improve the comfort of passengers. Another core of the present invention is to provide a rail vehicle, including the above train air supply control system, which can reduce the noise generated when the air compressor of the train operates and improve the comfort of passengers.

[0062] Please refer to Figure 1 , an embodiment of the present invention provides a train air supply control method, including the following steps S1 and S2:

[0063] Step S1: During the running of the train, calculate the air consumption speed of the train within a first preset time in real time.

[0064] Step S2: According to the air consumption speed, control the working frequency of the air compressor of the train to match the air consumption speed.

[0065] It should be noted that the first preset time here refers to a period of time before the current operation of the train, that is, a period of time before the current moment of the train, which is a definite period of time that can be preset in advance. Specifically, those skilled in the art can set it according to actual needs. The embodiments of the present invention do not specifically limit the specific duration of the first preset time.

[0066] In addition, the embodiments of the present invention do not limit the specific method for calculating the air consumption speed of the train within the first preset time. For example, it can be to obtain the air consumption volume of the train within the first preset time, and divide the air consumption volume by the first preset time to obtain the air consumption speed of the train. It can also be to use a pressure gauge and a flow meter to monitor the air consumption speed of the train in real time within the first preset time. Of course, there can also be other ways, as long as the air consumption speed of the train within the first preset time can be obtained.

[0067] In addition, it should be noted that the operating frequency refers to any value between the preset maximum frequency and the preset minimum frequency of the air compressor, and there is a preset relationship between it and the air consumption speed. For example, when the air consumption speed is relatively large, the operating frequency is relatively high; when the air consumption speed is relatively small, the operating frequency is relatively low. The embodiments of the present invention do not limit the specific matching relationship between the air consumption speed and the operating frequency, as long as the operating frequency of the air compressor is positively correlated with the air consumption speed.

[0068] That is to say, the train air supply control method provided by the embodiments of the present invention has the function of intelligently adjusting the operating frequency of the air compressor. By calculating the air consumption speed of the train within the first preset time in real time and controlling the output frequency of the air compressor of the train according to the air consumption speed, the operating frequency of the air compressor is matched with the air consumption speed. It can be understood that when the air consumption volume of the air-using equipment is small and the air consumption speed is low, at this time, through the train air supply control method of the present application, the operating frequency of the air compressor can be made low, thereby effectively reducing the noise during the operation of the air compressor, so that the air compressor can maintain a low noise under most working conditions of the normal operation of the train, which is beneficial to improving the user comfort and making the user experience good.

[0069] Further, please refer to Figure 2 , in order to meet the high air consumption demand of the air-using equipment in time and improve the vehicle safety, in some embodiments, after controlling the operating frequency of the air compressor of the train to match the air consumption speed, the train air supply control method further includes steps S3 - S5:

[0070] Step S3: During the operation of the air compressor, continuously calculate the pressure rise speed of the air cylinder of the train;

[0071] Step S4: Determine whether the pressure rise speed is lower than the preset value;

[0072] Step S5: If so, control the air compressor to output the preset maximum frequency.

[0073] That is to say, in this embodiment, not only is the working frequency of the air compressor of the train controlled to match the air consumption speed according to the air consumption speed, but also during the operation of the air compressor, the increase in the air pressure of the train's air cylinder is continuously monitored, and when the increase speed of the air pressure of the train's air cylinder is lower than the preset value, the air compressor is automatically switched to the working mode of outputting the preset maximum frequency, so as to increase the air supply volume to meet the working conditions with a large air consumption of the vehicle. This is beneficial to meeting the demand for a large air volume in the vehicle, ensuring air supply safety, and improving the safety of vehicle operation.

[0074] It can be understood that when the increase speed of the air pressure of the train's air cylinder is greater than the preset value, the above-mentioned step S2 can be continued, that is, the working frequency of the air compressor of the train is controlled to match the air consumption speed according to the air consumption speed.

[0075] In addition, please refer to Figure 2 , it can be understood that a pressure sensor is often used in the train to detect the air pressure of the train's air cylinder. In order to avoid affecting the control of the output frequency of the air compressor when the pressure sensor fails, in some embodiments, the train air supply control method further includes steps S6 and S7:

[0076] Step S6: When the train starts, determine whether the pressure sensor for detecting the air pressure of the train's air cylinder is abnormal;

[0077] Step S7: If so, control the air compressor to output the preset working frequency.

[0078] That is to say, in this embodiment, when the train starts, it is first determined whether the pressure sensor is faulty. If the pressure sensor has a fault or is abnormal, the working frequency of the air compressor of the train is no longer controlled to match the air consumption speed according to the air consumption speed, but the air compressor is directly controlled to output the preset working frequency to ensure the normal operation of the air compressor and avoid the air compressor from being unable to operate normally due to the influence of the abnormal pressure sensor.

[0079] It should be noted that the preset working frequency here is a working frequency set in advance, which is not related to the air consumption speed but is a fixed value. The preset working frequency is a value between the preset maximum frequency and the preset minimum frequency of the air compressor. The specific frequency value of the preset working frequency in this embodiment is not limited, and those skilled in the art can determine it according to experience or conventional techniques.

[0080] In addition, when the pressure sensor is normal rather than abnormal, the output frequency of the air compressor can be normally controlled according to the methods of the above-mentioned steps S1 and S2, so that the working frequency output by the air compressor matches the air consumption speed.

[0081] Further, please refer to Figure 2 , when the train starts, in order to reduce the train departure preparation time, in some embodiments, after determining whether the pressure sensor for detecting the wind cylinder pressure of the train is abnormal, it further includes:

[0082] Step S8: If the pressure sensor is normal, determine whether the current wind pressure detected by the pressure sensor is lower than a preset pressure threshold;

[0083] If so, control the air compressor to output a preset maximum frequency (that is, execute step S5).

[0084] That is to say, when the pressure sensor is normal and available, the pressure value detected by the pressure sensor is judged. When the current wind pressure detected by the pressure sensor is too low, it is defaulted that the train is in the initial air charging state. At this time, control the air compressor to output a preset maximum frequency to make the train reach the available state as soon as possible and reduce the train departure preparation time.

[0085] In addition, it can be understood that when the current wind pressure detected by the pressure sensor is greater than the preset pressure threshold, it indicates that the train is running normally. At this time, the output frequency of the air compressor can be continuously controlled according to the methods of step S1 and step S2 above, so that the working frequency output by the air compressor matches the air consumption speed.

[0086] In addition, in order to reduce the inrush current when the train starts, in some embodiments, the train air supply control method further includes:

[0087] When the air compressor starts, control the drive motor for driving the air compressor to output a preset low torque, and as the speed of the drive motor rises, control the output torque of the drive motor to increase.

[0088] That is to say, in this embodiment, the air compressor has a soft start function. At the moment when the air compressor starts, control the drive motor to output a preset low torque to reduce the starting current; and when the speed of the drive motor rises, increase the output torque of the drive motor to increase the speed of the drive motor, so as to meet the high-speed operation requirements of the drive motor. That is, in this embodiment, the working frequency of the air compressor is gradually increased after the air compressor starts, which is beneficial to making the starting current of the drive motor equivalent to its working current, avoiding the starting current of the drive motor exceeding the working current of the drive motor by too many times, and thus reducing the impact on the vehicle power supply system.

[0089] In addition, it can be understood that in the related art, for various vulnerable and consumable parts of the air compressor, such as air filters, oil filters, oil-gas separator filter elements, etc., they are replaced regularly according to experience. This results in inaccurate replacement cycles for various vulnerable and consumable parts. That is, when the replacement cycles of various vulnerable and consumable parts are relatively short, at this time, the equivalent total working hours of the air compressor are relatively short, and there is a situation where the vulnerable and consumable parts do not reach the damage standard, leading to over-maintenance; while when the replacement cycles of various vulnerable and consumable parts are relatively long, at this time, the equivalent total working hours of the air compressor are relatively long, and there is a risk that the functions of various vulnerable and consumable parts decline or fail. For example, there is a problem that the filtering effect of the filter element is not good, thus affecting the quality of the compressed air provided by the air compressor.

[0090] To solve the technical problem of inaccurate replacement cycles for various vulnerable and consumable parts of the air compressor, in some embodiments, the train air supply control method further includes:

[0091] Obtain the duration of the air compressor outputting different working frequencies;

[0092] Obtain the weighting coefficients corresponding to the durations of different working frequencies;

[0093] Calculate the cumulative equivalent total working hours of the air compressor according to the durations of different working frequencies and their corresponding weighting coefficients;

[0094] Obtain the service lives of various vulnerable and consumable parts of the air compressor;

[0095] Compare the equivalent total working hours with the service lives of various vulnerable and consumable parts;

[0096] When the equivalent total working hours reach the second preset time before the service lives corresponding to various vulnerable and consumable parts, control the alarm device of the train to issue a warning to replace the corresponding vulnerable and consumable parts, and when the equivalent total working hours reach the service lives corresponding to various vulnerable and consumable parts, control the alarm device to issue an alarm message to replace the corresponding vulnerable and consumable parts.

[0097] It can be understood that the output frequency of the air compressor has a certain impact on the service life of each vulnerable and consumable part of the air compressor. Therefore, when the operating frequency of the air compressor output controlled by the train is matched with the air consumption speed, the actual service life of each vulnerable and consumable part of the air compressor will change. Therefore, in order to more accurately predict the actual service life of each vulnerable and consumable part of the air compressor, in this embodiment, the cumulative sum of the weighted working hours when the air compressor works at each operating frequency is used as the equivalent total working hours of the air compressor, so as to predict the actual service life of each vulnerable and consumable part of the air compressor (for example, air filter, oil filter, oil and gas separator filter element, etc.). When the equivalent total working hours of the air compressor reach the second preset time before the service life corresponding to each vulnerable and consumable part, the alarm device of the train is controlled to issue a warning to replace the corresponding vulnerable and consumable part, so as to prompt the staff that the corresponding vulnerable and consumable part of the air compressor is about to need replacement, and when the equivalent total working hours of the air compressor reach the service life corresponding to each vulnerable and consumable part, the alarm device is controlled again to issue an alarm message to replace the corresponding vulnerable and consumable part, so that the staff can replace the corresponding vulnerable and consumable part in time. It can be seen that this embodiment is conducive to realizing intelligent maintenance. In this way, the actual service life of each vulnerable and consumable part can be more consistent with the service life, so that the vulnerable and consumable part can be replaced in time before it is damaged, avoiding the reduction or failure of the effect of the vulnerable and consumable part and affecting the quality of the compressed air output by the air compressor. At the same time, it is possible to avoid replacing the vulnerable and consumable parts too long in advance, thereby reducing the daily maintenance and inspection work, avoiding over-maintenance, and saving economic costs and time costs.

[0098] It should be noted that the specific duration of the second preset time in this embodiment is not limited. For example, the second preset time can be ten days, that is, a warning to replace the corresponding vulnerable and consumable part is given ten days before reaching the service life of the vulnerable and consumable part. Of course, it can also be other durations. In addition, the second preset time corresponding to each vulnerable and consumable part can be the same or different. It can be understood that when the vulnerable and consumable part is relatively easy to obtain, the second preset time can be relatively short, while when the vulnerable and consumable part is relatively difficult to obtain, or a relatively long time is required for preparation, the second preset time can also be relatively long.

[0099] In addition, it should be noted that the specific method for obtaining the weighting coefficients corresponding to the durations of different operating frequencies in this embodiment is not limited. It can be understood that the weighting coefficients of the durations of each operating frequency are related to the operating frequency. In some embodiments, the weighting coefficient of the duration of the operating frequency is equal to the ratio of the operating frequency to the preset standard frequency of the air compressor. For example, define A i as an operating frequency, A0 as the preset standard frequency of the air compressor, and a i as the operating frequency A iThe weighting coefficient corresponding to the duration, then a i = A i / A0, where i = 1, 2, … N, and N is a positive integer greater than or equal to 1.

[0100] In addition, this embodiment does not limit the method of calculating the equivalent total working duration accumulated by the air compressor according to the duration corresponding to different working frequencies and their corresponding weighting coefficients. In some embodiments, the equivalent total working duration of the air compressor is defined as T, and the working duration of the air compressor corresponding to the working frequency A i is T i of the corresponding air compressor, then the equivalent total working duration of the air compressor is: That is, the equivalent total working duration of the air compressor is equal to the sum of the products of the working durations of each working frequency and their corresponding weighting coefficients.

[0101] It should be noted that this embodiment of the present invention does not limit the specific implementation manner of the alarm device. For example, the alarm device can be a sound prompt device, a light display device, or a screen display device, etc. That is, the alarm device can send out voice information, screen display information, light information, etc., or a combination of multiple prompt information to send out a warning for replacing the corresponding vulnerable parts and an alarm message for replacing the corresponding vulnerable parts.

[0102] In addition, after replacing the vulnerable parts of the air compressor, in order to facilitate re-timing the equivalent total working duration of the air compressor for the newly replaced vulnerable parts, in some embodiments, the train air supply control method further includes:

[0103] When receiving the vulnerable parts replacement information, re-start timing the equivalent total working duration of the air compressor.

[0104] That is to say, when the vulnerable parts are replaced, a new round of intelligent diagnosis and life prediction for the replaced vulnerable parts is re-started.

[0105] In addition to the above train air supply control method, the present invention also provides a train air supply control system. The train air supply control system includes an air compressor and a controller. The air compressor is used to supply air to the train; the controller is connected to the air compressor, and the controller is used to implement the train air supply control method disclosed in any one of the above embodiments.

[0106] That is to say, the key point of this embodiment is that the controller of the train air supply control system is used to implement the train air supply control method disclosed in any one of the above embodiments. Therefore, the train air supply control system at least has the beneficial effects of the above train air supply control method.

[0107] It should be noted that the controller can be an independent controller newly added specifically for implementing the above-mentioned train air supply control method, and this controller can be installed on the air compressor; the controller can also be the existing network control host of the train or the controller of the braking system, etc., as long as the existing network control host of the train or the controller of the braking system can implement the above-mentioned train air supply control method.

[0108] In addition, please refer to Figure 3 , it can be understood that in some embodiments, the train air supply control system further includes a drive motor 13, an air cylinder 14, a pressure sensor 15, etc. Among them, the drive motor 13 is respectively connected to the controller 11 and the air compressor 12. The drive motor 13 is controlled by the controller 11 to drive the air compressor 12 to work to generate compressed air. The higher the rotation speed of the drive motor 13, the faster the air supply rate of the air compressor 12, and at the same time, the greater the noise; the air cylinder 14 is connected to the air compressor 12, and the pressure sensor 15 is connected to the controller 11. The pressure sensor 15 is used to detect the air pressure in the air cylinder 14 in real time and transmit the pressure signal to the controller 11.

[0109] In addition, in some embodiments, the train air supply control system further includes a reset key. The reset key is connected to the controller and is used to send a signal indicating that the replacement of vulnerable and consumable parts is completed to the controller after being triggered, so that the controller can restart timing the equivalent total working duration of the air compressor according to the received trigger signal of the reset key.

[0110] It should be noted that the reset key can be a reset button. For example, it can be a mechanical button set on the controller, or a button module set on the display screen, as long as pressing the reset key can send information indicating that the replacement of vulnerable and consumable parts is completed to the controller; of course, the reset key can also be other structural parts that can be operated and triggered, as long as operating the reset key can send a signal indicating that the replacement of vulnerable and consumable parts is completed to the controller.

[0111] Corresponding to the above-mentioned embodiments of the train air supply control method, an embodiment of the present invention also provides a train air supply control device, and the train air supply control device described below can be mutually corresponding and referred to with the train air supply control method described above.

[0112] Please refer to Figure 4 , the train air supply control device includes:

[0113] An air consumption speed calculation module 21, which is used to calculate the air consumption speed of the train in the first preset time in real time during the running of the train;

[0114] A first control module 22, which is used to control the air compressor of the train to output a working frequency matching the air consumption speed according to the air consumption speed.

[0115] It can be understood that the air consumption speed calculation module 21 is connected to the first control module 22 for information transmission. That is to say, during the train operation, the air consumption speed calculation module 21 calculates the air consumption speed of the train within the first preset time in real time and sends the air consumption speed to the first control module 22. The first control module 22 controls the working frequency of the train's air compressor output to match the air consumption speed according to the air consumption speed, so that the working frequency of the air compressor matches the air consumption speed. As can be seen from the above, the working frequency of the air compressor matches the air consumption speed. Compared with the fixed-frequency operation of the air compressor in the related art, the working frequency of the air compressor can be made low, thereby effectively reducing the noise generated when the air compressor works. In most working conditions during the normal operation of the train, the air compressor can maintain a low noise, which is beneficial to improving the user comfort and making the user experience good.

[0116] Further, in some embodiments, the train air supply control device further includes:

[0117] A wind pressure rising speed calculation module for continuously calculating the wind pressure rising speed of the train's air cylinder during the operation of the air compressor;

[0118] A first judgment module for judging whether the wind pressure rising speed is lower than a preset value;

[0119] A second control module for controlling the air compressor to switch to output a preset maximum frequency when the wind pressure rising speed is lower than the preset value.

[0120] It can be understood that the wind pressure rising speed calculation module is connected to the first judgment module, and the first judgment module is connected to the first control module for information transmission. That is to say, during the operation of the air compressor, the wind pressure rising speed calculation module continuously calculates the wind pressure rising speed of the train's air cylinder and sends the wind pressure rising speed to the first judgment module. The first judgment module judges whether the wind pressure rising speed is lower than the preset value and sends the judgment result to the second control module. The second control module controls the air compressor to switch to output a preset maximum frequency when the wind pressure rising speed is lower than the preset value. This can increase the air supply volume to meet the working conditions with a large air consumption of the vehicle, which is beneficial to meeting the large air volume working condition requirements of the vehicle, ensuring the air supply safety, and improving the safety of vehicle operation.

[0121] Further, in some embodiments, the train air supply control device further includes:

[0122] A second judgment module for judging whether the pressure sensor for detecting the wind pressure of the train's air cylinder is abnormal when the train starts;

[0123] A third control module for controlling the air compressor to output a preset working frequency when the pressure sensor is abnormal.

[0124] It can be understood that the second judgment module is connected to the third control module for information transmission. That is, when the train starts, the second judgment module is used to judge whether the pressure sensor for detecting the wind pressure of the train's air cylinder is abnormal, and send the pressure sensor abnormal signal to the third control module. Then, the third control module is used to control the air compressor to output a preset working frequency when the pressure sensor is abnormal. That is, in this embodiment, when the train starts, it first judges whether the pressure sensor is faulty. If the pressure sensor has a fault abnormality, the first control module is no longer executed, but the air compressor is directly controlled to output a preset working frequency to ensure the normal operation of the air compressor and prevent the air compressor from being unable to work properly due to the influence of the abnormal pressure sensor.

[0125] Further, in some embodiments, the train air supply control device further includes:

[0126] A third judgment module, configured to judge whether the current wind pressure detected by the pressure sensor is lower than a preset pressure threshold when the pressure sensor is normal;

[0127] A fourth control module, configured to control the air compressor to output a preset maximum frequency when the current wind pressure detected by the pressure sensor is lower than the preset pressure threshold.

[0128] It can be understood that the third judgment module is connected to the second judgment module, and the fourth control module is connected to the third judgment module for information transmission. That is, when the second judgment module judges that the pressure sensor is normal (not abnormal), it sends the pressure sensor normal information to the third judgment module. The third judgment module further judges whether the current wind pressure detected by the pressure sensor is lower than the preset pressure threshold. When the third judgment module judges that the current wind pressure detected by the pressure sensor is lower than the preset pressure threshold, the third judgment module sends the information that the current wind pressure detected by the pressure sensor is lower than the preset pressure threshold to the fourth control module, and the fourth control module controls the air compressor to output a preset maximum frequency. That is, when the pressure sensor is normal and available, the pressure value detected by the pressure sensor is judged. When the current wind pressure detected by the pressure sensor is too low, it is defaulted that the train is in the initial air charging state. At this time, the air compressor is controlled to output a preset maximum frequency to quickly bring the train to an available state and reduce the train departure preparation time.

[0129] Further, in some embodiments, the train air supply control device further includes:

[0130] A fifth control module, configured to control the drive motor for driving the air compressor to output a preset low torque when the air compressor starts, and control the output torque of the drive motor to increase as the speed of the drive motor rises.

[0131] That is to say, when the air compressor starts, the fifth control module is used to control the drive motor to first output a preset low torque. As the speed of the drive motor increases, the output torque of the drive motor is controlled to increase, so that the air compressor has a soft start function. At the moment when the air compressor starts, the drive motor is controlled to output a preset low torque to reduce the starting current. When the speed of the drive motor increases, the output torque of the drive motor is increased to increase the speed of the drive motor, so as to meet the high-speed operation requirement of the drive motor, which can reduce the impact on the vehicle power supply system.

[0132] Further, in some embodiments, the train air supply control device further includes:

[0133] A first acquisition module, configured to acquire the duration of the air compressor outputting different operating frequencies;

[0134] A second acquisition module, configured to acquire the weighting coefficients corresponding to the durations of different operating frequencies;

[0135] An equivalent total working duration calculation module, configured to calculate the accumulated equivalent total working duration of the air compressor according to the durations of different operating frequencies and their corresponding weighting coefficients;

[0136] A third acquisition module, configured to acquire the service lives of the various vulnerable and consumable parts of the air compressor;

[0137] A comparison module, configured to compare the equivalent total working duration with the service lives of the various vulnerable and consumable parts;

[0138] A sixth control module, configured to control the alarm device of the train to issue a warning to replace the corresponding vulnerable and consumable parts when the equivalent total working duration reaches a second preset time before the service lives of the various vulnerable and consumable parts, and to control the alarm device to issue an alarm message to replace the corresponding vulnerable and consumable parts when the equivalent total working duration reaches the service lives of the various vulnerable and consumable parts.

[0139] It can be understood that the first acquisition module and the second acquisition module are respectively connected to the equivalent total working duration calculation module, the equivalent total working duration calculation module and the third acquisition module are respectively connected to the comparison module, and the comparison module is connected to the sixth control module for information transmission.

[0140] That is to say, during the operation of the air compressor, the first acquisition module is used to acquire the duration of different operating frequencies output by the air compressor, and the first acquisition module is made to send the duration corresponding to each operating frequency to the equivalent total operating duration calculation module. The second acquisition module is used to acquire the weighting coefficients corresponding to the durations of different operating frequencies, and the second acquisition module is made to send the weighting coefficients corresponding to the durations of each operating frequency to the equivalent total operating duration calculation module. Then, the equivalent total operating duration calculation module is used to calculate the accumulated equivalent total operating duration of the air compressor according to the durations of different operating frequencies and their corresponding weighting coefficients, and the equivalent total operating duration calculation module is made to send the equivalent total operating duration to the comparison module. The third acquisition module is used to acquire the service lives of various vulnerable and consumable parts of the air compressor, and the third acquisition module is made to send the service lives of various vulnerable and consumable parts to the comparison module. The comparison module is used to compare the equivalent total operating duration with the service lives of various vulnerable and consumable parts and send the comparison result to the sixth control module. When the equivalent total operating duration reaches the second preset time before the service life corresponding to each vulnerable and consumable part, the sixth control module is used to control the alarm device of the train to issue a warning to replace the corresponding vulnerable and consumable part. When the equivalent total operating duration reaches the service life corresponding to each vulnerable and consumable part, the sixth control module is used to control the alarm device to issue an alarm message to replace the corresponding vulnerable and consumable part.

[0141] It can be seen that this embodiment is conducive to realizing intelligent maintenance. In this way, the actual life of each vulnerable and consumable part can be made more consistent with its service life, so that the corresponding vulnerable and consumable part can be replaced in time before it is worn out, avoiding the reduction or failure of the effect of the vulnerable and consumable part and affecting the quality of the compressed air output by the air compressor. At the same time, it is possible to avoid replacing the vulnerable and consumable parts too long in advance, thereby reducing the daily maintenance and inspection work, avoiding over-maintenance, and saving economic costs and time costs.
