Technical Field

[0001] The present application relates to the field of train air compressor control, and in particular to an air compressor control method, electronic equipment and medium. Background Art

[0002] In traditional rail transit, each train is equipped with 2 or 3 air compressors to meet the train's demand for wind power. The current control principle is: obtain the pressure value of the current vehicle. If the pressure value meets the requirements, all air compressors in the current train are controlled to start or stop at the same time.

[0003] However, with the development of rail transit, high-speed maglev trains have become an important means of transportation in rail transit. In the design of high-speed maglev trains, each car is equipped with an air compressor, and the air compressors of the entire train are distributed on two air paths. Since the pressure difference in different air paths may be different, the existing air compressor control method in rail vehicles cannot meet the control requirements of air compressors in current high-speed maglev trains.

[0045] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0046] The core of this application is to provide an air compressor control method, electronic equipment and medium.

[0047] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0048] FIG1 is a flow chart of an air compressor control method provided in an embodiment of the present application, as shown in FIG1 , including the following process:

[0049] S10: Obtain the start / stop parameters and serial numbers of the corresponding air compressors in each compartment.

[0050] S11: Determine the air path where the air compressor corresponding to the serial number is located according to the serial number classification rule.

[0051] In a specific embodiment, the air compressor control method currently provided is applied to a high-speed maglev train, and there is an air compressor in each carriage of the high-speed maglev train, and multiple air compressors in the train are arranged in two air circuits. This application first obtains the serial number of each air compressor, and determines the air circuit where the air compressor corresponding to the serial number is located according to the serial number classification rule, that is, it can be clear which air compressors are specifically included in different air circuits, so as to realize air circuit level control.

[0052] Among them, as a preferred embodiment, the serial number classification rules can be as shown in Table 1.

[0053] Table 1

[0054]

[0055] Take two air circuits and two carriages as an example: the air compressor corresponding to the front carriage MC1 is set in air circuit 1; the air compressor corresponding to the first carriage M1 is set in air circuit 2; the air compressor corresponding to the second carriage M2 is set in air circuit 1, and the air compressor corresponding to the rear carriage MC2 is set in air circuit 2, as shown in Figure 2.

[0056] It should be noted that the air compressors of adjacent vehicles shown in FIG2 are alternately arranged in two air circuits. Through the two-way valves set at both ends of the vehicle, both air circuits can redundantly provide compressed air to the air-using equipment on the vehicle. When one air circuit fails, the other air circuit can ensure the air supply to the vehicle. At the same time, since the air compressors are alternately arranged in the two air circuits, and it is necessary to keep walking on both sides of the train to inspect and repair the air compressors of the train, most of the structures shown in FIG2 cross air circuit 1 and air circuit 2, so as to ensure that the air compressors are alternately arranged in different air circuits and on the same side of the vehicle as much as possible.

[0057] It should be noted that the structure shown in FIG. 2 is only one possible implementation method, but is not limited to this implementation method and can be set according to user needs.

[0058] S12: Determine the corresponding gas circuit level start / stop command according to the start / stop parameters of the air compressor in the same gas circuit.

[0059] S13: Control the air compressor in the same gas circuit according to the gas circuit level start and stop instructions.

[0060] In a specific embodiment, after the air compressors specifically included in different air circuits are determined, the air circuit-level control of the train is implemented, that is, the corresponding air circuit-level start and stop instructions are determined according to the start and stop parameters of the air compressor in the same air circuit, and then the air compressor in the same air circuit is controlled according to the air circuit-level start and stop instructions.

[0061] The start and stop parameters of each air compressor are determined according to the total air pressure value and the set pressure value of different air circuits and locations, so the start and stop parameters corresponding to different air compressors are different. However, the total air pressure value in the same air circuit will not differ much, so the corresponding air circuit-level start and stop instructions for the entire air circuit can be determined based on the start and stop parameters of any or all air compressors in the current air circuit.

[0062] For example, when the start / stop parameters corresponding to any air compressor in the same gas circuit indicate that the air compressor is in operation, the gas circuit-level start / stop command is the gas circuit-level operation command, which controls all the air compressors in the current gas circuit to start.

[0063] The present application provides an air compressor control method, including: obtaining the start / stop parameters and serial numbers of the corresponding air compressors in each compartment; determining the air circuit in which the air compressor corresponding to the serial number is located according to the serial number classification rules; determining the corresponding air circuit-level start / stop instructions according to the start / stop parameters of the air compressor in the same air circuit; and controlling the air compressors in the same air circuit according to the air circuit-level start / stop instructions. It can be seen that the present application classifies the air circuits of the air compressors according to their serial numbers, and then controls the start / stop of all the air compressors in the same group of air circuits according to the start / stop parameters of the air compressors in the current air circuit, thereby realizing separate control of different air circuits. It avoids the problem of damage to the air compressor caused by overall control due to different air pressures in different air circuits.

[0064] On the basis of the above embodiments, as a preferred embodiment, the corresponding gas circuit level start and stop instructions are determined according to the start and stop parameters of the air compressor in the same gas circuit, which include one operation instruction and three shutdown instructions.

[0065] Among them, the operation instruction is: if the start / stop parameters corresponding to any air compressor in the same gas circuit indicate that the air compressor is in operation (that is, the total air pressure value in any air compressor is less than the set pressure value), then the gas circuit-level start / stop instruction is the gas circuit-level operation instruction, that is, controlling the operation of all air compressors in the current gas circuit.

[0066] Among them, the first type of shutdown command is: if the vehicle speed is in the first vehicle speed range, and the start-stop parameters corresponding to any air compressor detected in the same air circuit indicate that the air compressor is in a shutdown state (that is, the total air pressure value in any air compressor reaches the set pressure value), then the air circuit-level start-stop command is the air circuit-level shutdown command, that is, all the air compressors in the current air circuit are controlled to shut down.

[0067] The second type of shutdown command is: if the vehicle speed is in the second vehicle speed range, and the start and stop parameters corresponding to each air compressor detected in the same air circuit all indicate that the air compressor is in a shutdown state (that is, the total air pressure values ​​in all air compressors in the current air circuit have reached the set pressure value), then the air circuit-level start and stop command is an air circuit-level shutdown command, that is, all air compressors in the current air circuit are controlled to shut down.

[0068] The third type of shutdown command is: if the vehicle speed is in the second speed range, the start-stop parameters corresponding to the first air compressor detected in the same air circuit indicate that the air compressor is in a shutdown state (that is, only the total air pressure value in the first air compressor reaches the set pressure value), and the current shutdown time is greater than the preset time (for example, 60 seconds), then the air circuit-level start-stop command is an air circuit-level shutdown command, that is, all air compressors in the current air circuit are controlled to shut down.

[0069] Among them, the first speed range belongs to the low speed range, and the second speed range belongs to the high speed range. Its operation command and the first stop command are determined according to the start and stop parameters of any air compressor in the same air circuit; and the dynamic air consumption of the train when running at high speed is greater than the dynamic air consumption when running at low speed, so the second stop command is determined according to the start and stop parameters corresponding to all air compressors in the same air circuit; and because the air compressor corresponding to individual carriages is in a fault (such as a shutdown pressure switch fault), in order to avoid the air compressor on the air circuit from working for too long and causing an over-temperature alarm, the third stop command is determined according to the start and stop parameters of the first air compressor.

[0070] It should be noted that the embodiment provided in the present application is only one possible implementation method, but is not limited to only this implementation method and can be set according to the needs of the user.

[0071] The present application provides a specific determination method for determining the corresponding gas circuit-level start-stop command according to the start-stop parameters of the air compressor in the same gas circuit. The method clarifies the relationship between the running command and the start-stop parameters of the air compressor, and the relationship between the stop command and the start-stop parameters and speed of the air compressor. In this method, the gas circuit-level start-stop commands corresponding to different gas circuits in the current scenario can be quickly determined to achieve gas circuit-level control of the train.

[0072] On the basis of the above-mentioned embodiments, since the air circuit level control needs to ensure the network connection between the vehicle and the carriage, there may be unstable situations. Therefore, the present application adds redundant control to the above-mentioned air circuit level control, that is, vehicle-level control, and its specific steps are: obtaining the operating parameters of the corresponding air compressor in each carriage, which is specifically used to determine the status of each air compressor itself; then obtaining the network connection status of each carriage, which is specifically used to determine the priority of air circuit level control and vehicle-level control, which is specifically divided into three situations.

[0073] The first type of situation: if the operating parameters do not meet the normal operating standards, such as the temperature parameters in the operating parameters are too high, it means that the current air compressor is in a faulty state, and the air circuit level control is only related to the start-stop parameters. Therefore, at this time, regardless of whether the network connection status represents an abnormal or normal connection between the vehicle and the carriage, the specific control is vehicle-level control, that is, the corresponding vehicle-level start-stop instructions are determined according to the start-stop parameters of each air compressor. If it is detected that the start-stop parameters corresponding to the air compressor represent that the air compressor is in a shutdown state or a running state, the vehicle-level start-stop instruction is a vehicle-level shutdown instruction. In other words, when the air compressor fails, the priority of the vehicle-level control (vehicle-level start-stop instruction) is higher than the priority of the air circuit level control (air circuit level start-stop instruction), and in this control, no matter what state the start-stop parameters represent, the air compressor is in a shutdown state.

[0074] The second case: If the operating parameters meet the normal operating standards, the manual states that the current air compressor can operate normally or shut down. When the network connection status indicates that the connection between the vehicle and the carriage is abnormal, it means that the air circuit level control command cannot be sent to the air compressor normally. Therefore, only vehicle-level control can be used at this time, that is, the corresponding vehicle-level start-stop command is determined according to the start-stop parameters of each air compressor. If it is detected that the start-stop parameters corresponding to the air compressor indicate that the air compressor is in an operating state, the vehicle-level start-stop command is a vehicle-level operating command; if it is detected that the start-stop parameters corresponding to the air compressor indicate that the air compressor is in a shutdown state, the vehicle-level start-stop command is a vehicle-level shutdown command. In other words, when the air compressor has no faults and the network connection status indicates that the connection between the vehicle and the carriage is abnormal, the priority of the vehicle-level control (vehicle-level start-stop command) is higher than the priority of the air circuit level control (air circuit level start-stop command).

[0075] In the third case, if the operating parameters meet the normal operating standards, the manual indicates that the current air compressor can operate or shut down normally. When the network connection status indicates that the vehicle and the compartment are connected normally, it means that the air circuit level control command can be sent to the air compressor normally. At this time, the step of determining the corresponding air circuit level start and stop command according to the start and stop parameters of the air compressor in the same air circuit is triggered. In other words, when the air compressor has no faults and the network connection status indicates that the vehicle and the compartment are connected normally, the priority of its air circuit level control (air circuit level start and stop command) is higher than the priority of the vehicle level control (vehicle level start and stop command).

[0076] It should be noted that the embodiment provided in the present application is only one possible implementation method, but is not limited to only this implementation method and can be set according to the needs of the user.

[0077] The present application provides a two-level redundant air compressor control method, which takes into account the status of the air compressor itself and the current status of the train network, and is more comprehensive to ensure that the air compressor can be effectively controlled under any circumstances.

[0078] On the basis of the secondary redundant control, a third-level redundant control can be designed, namely, gas circuit level control, vehicle level control and inverter level control. The third-level inverter level control is similar to the second-level vehicle level control, and also includes three situations:

[0079] The first case: if the operating parameters do not meet the normal operating standards, it means that the current air compressor is in a faulty state. At this time, regardless of whether the network connection status indicates that the connection between the carriage and the air compressor inverter is abnormal or normal, the specific control is the inverter-level start-stop command, that is, the corresponding inverter-level start-stop command is determined according to the start-stop parameters of each air compressor. If it is detected that the start-stop parameters corresponding to the air compressor indicate that the air compressor is in a shutdown state or a running state, the inverter-level start-stop command is an inverter shutdown command. In other words, when the air compressor fails, the priority of its three-level redundant control is from high to low: inverter-level control (inverter-level start-stop command), vehicle-level control (vehicle-level start-stop command), and gas circuit-level control (gas circuit-level start-stop command). In this control, regardless of the state represented by the start-stop parameters, the air compressor is in a shutdown state.

[0080] The second case: If the operating parameters meet the normal operating standards, the manual states that the current air compressor can operate normally or shut down. If the network connection status indicates that the connection between the carriage and the air compressor inverter is abnormal, it means that the current gas circuit level control command or vehicle level control command cannot be sent to the air compressor normally. Therefore, only inverter level control can be used at this time, that is, the corresponding inverter level start and stop command is determined according to the start and stop parameters of each air compressor. If it is detected that the start and stop parameters corresponding to the air compressor indicate that the air compressor is in operation, the inverter level start and stop command is an inverter level operation command (supplying power to the air compressor); if it is detected that the start and stop parameters corresponding to the air compressor indicate that the air compressor is in shutdown, the inverter level start and stop command is an inverter level shutdown command. That is to say, when the air compressor has no faults and the network connection status indicates that the connection between the car and the inverter is abnormal, the priority of its three-level redundant control is from high to low: inverter-level control (inverter-level start and stop commands), vehicle-level control (vehicle-level start and stop commands), and gas circuit-level control (gas circuit-level start and stop commands).

[0081] The third case: If the operating parameters meet the normal operating standards, the current air compressor in the manual can operate normally or shut down, and its network connection status indicates that the connection between the car and the air compressor inverter is normal, which means that the vehicle-level control command can be sent to the air compressor normally. Therefore, vehicle-level control can be used at this time, that is, triggering the step of determining the corresponding vehicle-level start-stop command according to the start-stop parameters of each air compressor. At this time, the priority of the three-level redundant control is from high to low: vehicle-level control (vehicle-level start-stop command), inverter-level control (inverter-level start-stop command). If in this case, the network connection status also indicates that the connection between the vehicle and the car is normal, then the priority of the three-level redundant control is from high to low: gas circuit-level control (gas circuit-level start-stop command), vehicle-level control (vehicle-level start-stop command), inverter-level control (inverter-level start-stop command).

[0082] It should be noted that, in vehicle-level control or inverter-level control, if the pressure parameter in the operating parameters of the air compressor changes from meeting the normal pressure standard to not meeting the normal pressure standard during the control process, the current state of the air compressor is maintained. In other words, the pressure parameter is within the normal pressure standard at the beginning, and the air compressor is running or stopped at this time. During the operation of the air compressor, the pressure parameter inside the air compressor changes. At this time, the pressure parameter is not within the normal pressure standard, that is, the air compressor is not in a fault state at this time, so the current operation is still maintained.

[0083] In summary, the architecture of the air compressor of the high-speed maglev train to which the three-level redundant air compressor control method provided in the present application is applied is shown in FIG3 , and the interactive information of different levels of control in the train is shown in FIG4 .

[0084] It can be seen that the air compressor itself has no start-stop control function. It uses internal start-stop parameters (determined by the start pressure switch and the stop pressure switch) and operating parameters (determined by the temperature switch and the operating pressure switch) and relies on the air compressor inverter on the vehicle (to achieve inverter-level control), the vehicle-level network (to achieve vehicle-level control), and the train-level network (to achieve air circuit-level control) to perform logical processing on the data, and ultimately controls the start and stop of the air compressor by controlling the output power supply of the air compressor inverter.

[0085] Its control priority level (its air compressor has no fault):

[0086] When the network connection is normal, the train-level control > vehicle-level control > inverter-level control; that is, when there is no abnormality in the train-level network, the train-level control instructions are executed;

[0087] When the communication status between the vehicle and a certain car is abnormal, the vehicle-level control cannot receive the "gas-level start-stop command" of the gas-level control. The gas-level control of the vehicle fails and is transferred to vehicle-level control. That is, when the train-level communication is abnormal and the vehicle-level is normal, the vehicle-level network control is executed;

[0088] When the communication status between the inverter of the vehicle's air compressor and the car is abnormal, the inverter cannot receive the "vehicle-level start and stop command" sent by the vehicle-level control, and it is switched to the inverter control level.

[0089] In addition, during the test or debugging process of the maglev train, there is a single-car operation condition. In this condition, the train-level control fails, and the air compressor is started and stopped through vehicle-level control and inverter-level control.

[0090] In addition to the automatic start and stop control of the air compressor, a manual start and stop control function can also be set for debugging tests, such as forcing the air compressor to work to verify the safety valve function. For example, the air compressor of a certain car can be forced to run through the train-level network. During manual control, it does not consider whether the car has reached the air compressor starting pressure, whether it has reached the air compressor shutdown pressure, and whether there is an air circuit-level start and stop command from the air circuit-level control. The air circuit-level start and stop command can be automatic control or manual control of the train-level network, and the two are independent of each other and do not affect each other.

[0091] At the same time, when a vehicle's air compressor fails and is not suitable for continued operation, in order to avoid further impact, manual settings can be allowed to prohibit its continued operation, and the air compressor of a vehicle can be disabled / restored through the gas circuit level control. When the vehicle-level control of a vehicle receives the air compressor disable command issued by the gas circuit level control, it will no longer issue a "vehicle-level operation command" and send the disable command to the air compressor inverter, and the air compressor inverter will be prohibited from powering on.

[0092] It can be seen that the air compressor control method provided by this application specifically implements three-level redundant control, which avoids the instability caused by the first-level control. In different scenarios, the three-level redundant control corresponds to different priorities, which expands the application scenarios of the method and ensures the reliable start and stop of the air compressor and the air supply demand of the maglev vehicle.
