[0034] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0035] Example 1

[0036] In this embodiment, Figure 1 As shown, a method for controlling an air compressor of a locomotive group is provided, which includes:

[0037] Step 110: Obtain a first preset reference value and a second preset reference value.

[0038] In this embodiment, the first preset reference value and the second preset reference value are used to provide a reference for controlling the air compressor, and the first preset reference value and the second preset reference value provide a reference for the number of vehicles.

[0039] Step 120: Obtain the number of vehicles in the train.

[0040] Specifically, the number of vehicles in the train refers to the number of vehicles on a single train.

[0041] Step 130: Compare the number of vehicles with the first preset reference value and the second preset reference value to obtain a comparison result.

[0042] In this embodiment, the number of vehicles is compared with the first preset reference value and the second preset reference value respectively to obtain a comparison result.

[0043] Step 140: Based on the comparison result, control the corresponding air compressor to operate.

[0044] In this embodiment, based on the comparison result of the number of vehicles, the air compressors corresponding to the comparison result are controlled to operate, thereby meeting the air demand on the train.

[0045] In the above embodiment, the air compressor is controlled based on the comparison results of the number of vehicles with the first preset reference value and the second preset reference value. This can effectively match the number of vehicles on the train to control the air compressor, so that the wind provided by the air compressor can meet the air demand of the train, and can effectively avoid the problem of low operating rate of the air compressor, and also avoid the problem of too long working time of the air compressor, thereby achieving energy-saving effect.

[0046] In one embodiment, the step of controlling the operation of the corresponding air compressor based on the comparison result includes: when the number of vehicles is less than or equal to the first preset reference value, starting the first preset number of air compressors of the locomotive group; when the number of vehicles is greater than the first preset reference value and less than or equal to the second preset reference value, starting the second preset number of air compressors of the locomotive group; when the number of vehicles is greater than the second preset reference value, starting the third preset number of air compressors of the locomotive group; wherein, the first preset reference value is less than the second preset reference value, the first preset number is less than the second preset number, and the second preset number is less than the third preset number.

[0047] In this embodiment, when the number of vehicles is less than or equal to the first preset reference value, it indicates that the number of vehicles is small, therefore, fewer air compressors are controlled to work, and the first preset number of air compressors are controlled to start; when the number of vehicles is greater than the first preset reference value and less than or equal to the second preset reference value, it indicates that the number of vehicles is large, therefore, more air compressors are controlled to work, and the second preset number of air compressors are controlled to start; when the number of vehicles is greater than the second preset reference value, it indicates that the number of vehicles is very large, therefore, as many air compressors as possible are controlled to work, the third preset number of air compressors are controlled to start, and all the air compressors of the locomotive group are controlled to start. In this way, controlling the start of the corresponding number of air compressors according to the comparison results can ensure that the wind provided by the air compressor can meet the requirements of the number of vehicles on the train and the air demand of the train, effectively avoiding the problem of low working rate of the air compressor and the problem of too long working time of the air compressor, thereby achieving energy-saving effect.

[0048] In one embodiment, the step of obtaining the first preset reference value and the second preset reference value includes: obtaining the wind source capacity parameters of the locomotive group, the vehicle air volume information and the environmental road condition information; and calculating the first preset reference value and the second preset reference value based on the wind source capacity parameters of the locomotive group, the vehicle air volume information and the environmental road condition information.

[0049] In this embodiment, the wind source capacity parameter is used to indicate the capacity of the locomotive group's wind sources other than the wind compressor to provide wind energy, the vehicle air volume information is used to indicate the vehicle's demand for air volume, and the environmental road condition information is used to indicate parameters affecting wind energy, including weather and road conditions. In this embodiment, the first preset reference value and the second preset reference value are calculated based on the locomotive group's wind source capacity parameter, the vehicle air volume information, and the environmental road condition information. This allows the first preset reference value and the second preset reference value to be correlated with the wind source capacity parameter, the vehicle air volume information, and the environmental road condition information. This allows the comparison result of the number of vehicles to be consistent with the wind source capacity parameter, the vehicle air volume information, and the environmental road condition information. This effectively improves the utilization rate of the air compressor and avoids waste of air compressor energy, thereby effectively saving energy.

[0050] In one embodiment, the wind source capability parameter is proportional to the first preset reference value, and the wind source capability parameter is proportional to the second preset reference value. In one embodiment, the vehicle air volume information is inversely proportional to the first preset reference value, and the wind source capability parameter is inversely proportional to the second preset reference value.

[0051] In this embodiment, the wind source capacity parameter is used to indicate the ability of the locomotive group's other wind sources other than the wind compressor to provide wind energy. The larger the wind source capacity parameter is, the smaller the number of air compressors required is. Therefore, the larger the first preset reference value and the second preset reference value are. In this way, since the first preset reference value and the second preset reference value are larger, the number of vehicles tends to be smaller than the first preset reference value and the second preset reference value in comparison, and it is often easy to select a smaller first preset number to start fewer air compressors. Since the wind source capacity parameter indicates that the wind energy provided by other wind sources is larger, starting fewer air compressors can also meet the wind energy demand, thereby effectively saving the energy consumption of the air compressor.

[0052] The vehicle air volume information is used to indicate the vehicle's demand for air volume. The larger the vehicle air volume information, the greater the demand for wind energy for the air compressor. Therefore, the smaller the first preset reference value and the second preset reference value. In this way, since the first preset reference value and the second preset reference value are small, the number of vehicles tends to be greater than the first preset reference value or the second preset reference value in comparison, and it is often easy to select the larger second preset number or the third preset number to start more air compressors or start all air compressors, thereby meeting the larger air volume demand.

[0053] In one embodiment, in the step of calculating the first preset reference value and the second preset reference value based on the wind source capacity parameter of the locomotive assembly, the vehicle air volume information, and the environmental road condition information, the following formula is used to determine the first preset reference value and the second preset reference value:

[0054] v=B+m1*c / 2P-kZ

[0055] v=B+m2*c / 4P-kZ

[0056] Among them, the rated displacement of each air compressor is P, the vehicle air consumption information includes the locomotive group's own air consumption B and the air consumption of each vehicle section c, the air compressor working rate is v, the wind source capacity parameter is z, k is the wind energy coefficient, and the environmental road condition information includes the ambient temperature T, ambient humidity R, and ambient air pressure P. Among them, the locomotive group's own air consumption is B, which is positively correlated with T and R, and negatively correlated with P. The air consumption of each vehicle section is positively correlated with T and R, and negatively correlated with P.

[0057] In one embodiment, the locomotive set is a six-car locomotive set, the number of air compressors in the six-car locomotive set is four, and the third preset number is four.

[0058] In this embodiment, Figure 4 and Figure 5As shown, taking a six-car locomotive set as an example for further explanation, the first preset number is 2, the second preset number is 3, the third preset number is 4, and the total number of air compressors in the six-car locomotive set is 4.

[0059] (1) If n≤m1, only the two air compressors configured for the six-car locomotive group are controlled to start, and during operation, the two air compressors are started in turn. This can meet the air blowing time requirements of the train group and ensure the working rate of the compressors on the six-car locomotive group;

[0060] (2) If m2≥n>m1, only the three air compressors configured for the six-car train set are started, and the three air compressors are started in turn during operation. This can meet the air-blowing time requirements of the train set and ensure the working rate of the compressors on the six-car train set.

[0061] (3) If n>m2, all the air compressors configured for the six-car train set are controlled to start, and at the same time, the four air compressors are guaranteed to work simultaneously during the entire operation of this train set, which can meet the ventilation time requirements of the train set and ensure the working rate of the compressors on the six-car train set.

[0062] It should be understood that although Figure 1 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. In addition, Figure 1 At least part of the steps may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least part of the sub-steps or stages of other steps.

[0063] Example 2

[0064] In this embodiment, Figure 4 As shown, the locomotive set is a six-carriage locomotive set, including car A, car C1, car D1, car D2, car C2, and car B. Car A, car D1, car D2, and car B are respectively equipped with air compressors M1, M2, M3, and M4, that is, the maximum number of air compressors in the six-carriage locomotive set is 4. In this embodiment, the first preset number is 2, the second preset number is 3, and the third preset number is 4, and the total number of air compressors in the six-carriage locomotive set is 4.

[0065] The locomotive control system (CCU) uses the number of cars n as input based on the train formation, which is entered by the user. It calculates and sets two car number values, m1 and m2, based on the air source capacity of the six-car locomotive set, combined with information on the air volume used by the cars and the operating environment and road conditions.

[0066] The CCU automatically adjusts the starting strategy of the six-car locomotive air compressor corresponding to the specific formation by comparing the input value n with m1 and m2, such as Figure 5 As shown, specifically:

[0067] (1) If n≤m1, only the two air compressors configured for the six-car locomotive group are controlled to start, and during operation, the two air compressors are started in turn. This can meet the air blowing time requirements of the train group and ensure the working rate of the compressors on the six-car locomotive group;

[0068] (2) If m2≥n>m1, only the three air compressors configured for the six-car train set are started, and the three air compressors are started in turn during operation. This can meet the air-blowing time requirements of the train set and ensure the working rate of the compressors on the six-car train set.

[0069] (3) If n>m2, all the air compressors configured for the six-car train set are controlled to start, and at the same time, the four air compressors are guaranteed to work simultaneously during the entire operation of this train set, which can meet the ventilation time requirements of the train set and ensure the working rate of the compressors on the six-car train set.

[0070] According to the different number n of vehicles in different train formations and the changes in the train operating environment, the values ​​of m1 and m2 can be appropriately adjusted. Through the judgment of the n value by CCU, the appropriate logical control of the air compressor of the six-train locomotive group is selected to achieve the good effect of meeting the ventilation time requirements of the train formation and ensuring the working rate of the compressor on the six-train locomotive group.
