Description

Technical Field

[0001] This invention relates to the field of locomotive technology, and in particular to a method, system and controller for controlling wheel flange lubrication. Background Technology

[0002] When locomotives and rolling stock are in operation, friction and wear between the wheels and rails are inevitable, especially the wear between the wheel flanges and rails. With the rapid development of rail transit, there are many curves on the track, especially small-radius curves, which makes the wheel-rail wear problem increasingly prominent, not only shortening the service life of the wheels and rails, but also increasing energy consumption.

[0003] In related technologies, wheel flange lubrication is typically achieved through timed or spaced grease spraying; alternatively, it can be done via a wheel flange lubrication system or by using centrifugal force to identify curves and spray grease; or, grease spraying can be controlled using multi-threshold judgment. Of these methods, timed or spaced grease spraying cannot identify the curvature of the locomotive's running track, resulting in grease spraying amounts that do not match the actual needs of the locomotive, leading to inconsistent grease levels. Methods using wheel flange lubrication systems or centrifugal force for curve identification and grease spraying have limited functional scenarios, poor applicability, require significant work for updating track data, and incur high equipment maintenance costs. Methods using multi-threshold judgment for grease spraying control involve numerous and difficult-to-accurate threshold parameters, leading to inaccurate grease spraying amounts, poor control efficiency, and consequently, poor wheel flange lubrication. Under certain operating conditions, inaccurate grease spraying can cause slippage or idling, affecting driving safety. Summary of the Invention

Based on different operating conditions, it dynamically controls and outputs configuration parameters for grease spraying commands, adapting in real-time to the actual needs of locomotives and rolling stock. This achieves precise control of grease spraying commands, has wide applicability, reduces data computation and equipment maintenance costs, improves control efficiency and wheel flange lubrication effect, and ensures driving safety while effectively implementing wheel flange lubrication. Another objective of this invention is to provide a vehicle wheel flange lubrication control system. A further objective is to provide a controller.

[0056] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0057] It should be noted that the vehicle wheel flange lubrication control method, system and controller disclosed in this application can be used in the field of artificial intelligence technology, or in any field other than artificial intelligence technology. The application field of the vehicle wheel flange lubrication control method, system and controller disclosed in this application is not limited.

[0058] To facilitate understanding of the technical solution provided in this application, the relevant content of the technical solution will be explained below. Wheel flange lubrication not only relies on its own function but also needs to be considered in conjunction with the actual operating conditions of locomotives and rolling stock. The nozzle of the wheel flange lubrication device is mounted on the bogie. During installation, the nozzle is aimed at the junction of the wheel flange and the tread. Theoretically, when lubrication is needed, grease is sprayed onto the junction. However, when locomotives and rolling stock are in dynamic motion, due to the relative displacement between the bogie and the wheel axle, the spray position inevitably deviates slightly. Under certain operating conditions, if the spray position is biased towards the wheel tread, it can cause slippage or wheel spin, affecting driving safety. The research and application of wheel flange lubrication technology in this invention can not only effectively solve the wheel-rail wear problem but also reduce the internal shear stress of the wheel and rail, which is beneficial to reducing contact fatigue damage on the wheel-rail surface and reducing the wheel derailment coefficient, and also helps to improve vehicle operating safety. This invention, starting from the overall operation of locomotives and rolling stock, proposes a vehicle wheel flange lubrication control method that combines vehicle network integration with lateral vibration energy detection of the car body, effectively implementing wheel flange lubrication while preventing adverse effects on driving safety.

[0059] Figure 1 This is a schematic diagram of a vehicle wheel flange lubrication control system provided in an embodiment of the present invention, as shown below. Figure 1 As shown, the system includes a controller 100 and a solenoid valve 200, with the controller 100 and the solenoid valve 200 being communicatively connected.

[0060] In this embodiment of the invention, the controller 100 includes a power module 101 and an interface circuit 102.

[0061] The controller 100 is used to acquire the vehicle's operating data indicators and operating condition indicators; based on the operating data indicators and pre-generated standard data indicators, it generates grease spraying instructions configured with grease spraying configuration parameters; based on the operating condition indicators, it performs logical processing on the grease spraying configuration parameters, and controls the output of grease spraying instructions under different operating conditions according to the logically processed grease spraying configuration parameters.

[0062] The solenoid valve 200 is used to spray grease onto the wheel flange in response to the grease spraying command, thereby achieving the wheel flange lubrication function.

[0063] like Figure 1 As shown, the system also includes: power supply 300, vehicle network 400, and vehicle hardwire 500.

[0064] The power supply 300 is connected to the controller 100 through the power module 101, and the power supply 300 is used to supply power to the controller 100. Specifically, the power supply 300 undergoes electromagnetic compatibility (EMC) processing after entering the power module 101.

[0065] The vehicle network 400 and the vehicle hardwire 500 are connected to the controller 100 via the interface circuit 102. The vehicle network 400 provides a communication line between the vehicle and the controller 100. The vehicle network 400 can be an Ethernet communication network or a Multifunction Vehicle Bus (MVB) communication network. The controller 100 can obtain vehicle operating data and working condition data in real time through the vehicle communication protocol provided by the vehicle network 400.

[0066] The vehicle hardwire 500 provides the vehicle with start-up and operation signals and backup control signals. The start-up and operation signal indicates that the locomotive and rolling stock are running at a speed greater than a preset speed value, indicating that the vehicle has started running. As an optional option, the preset speed value is 5 kilometers per hour (km / h). The backup control signal provides the controller with the vehicle's operating status when the vehicle network fails. When the vehicle network fails, a high level of the backup control signal indicates that the locomotive and rolling stock are running, and a low level indicates that the locomotive and rolling stock are stationary. When the vehicle network experiences a communication failure, the vehicle hardwire 500 is used for flange lubrication control.

[0067] like Figure 1 As shown, the controller also includes: an acceleration sensor 103, a central processing unit 104, a display parameter setting circuit 105, and an output drive circuit 106.

[0068] Accelerometer 103 is connected to central processing unit 104 and is used to acquire vehicle acceleration. Specifically, accelerometer 103 is used to detect the lateral acceleration of the locomotive perpendicular to the direction of travel. As an optional solution, accelerometer 103 is selected as ADXL203CE.

[0069] The central processing unit 104 receives the vehicle acceleration data processed by the signal conditioning circuit and performs data synthesis and processing based on the vehicle acceleration. As an optional solution, the central processing unit 104 uses the C8051F020.

[0070] The display parameter setting circuit 105 is connected to the central processing unit 104. The display parameter setting circuit 105 is used to control the setting and display of thresholds, operating data indicators and operating condition indicators.

[0071] The output drive circuit 106 is connected to both the central processing unit 104 and the solenoid valve 200. The output drive circuit 106 outputs the grease spraying command from the central processing unit 104 to the solenoid valve 200, thereby driving the solenoid valve 200 to spray grease onto the vehicle wheel rim. Alternatively, the output drive circuit 106 can be an optocoupler-isolated circuit with the drive circuit.

[0072] The technical solution provided in this invention involves acquiring vehicle operating data indicators and operating condition indicators; generating grease spraying commands with configured grease spraying parameters based on the operating data indicators and pre-generated standard data indicators; logically processing the grease spraying configuration parameters according to the operating condition indicators; and controlling the output of grease spraying commands under different operating conditions according to the logically processed grease spraying configuration parameters to drive the solenoid valve to spray lubricating grease onto the vehicle wheel flange. This integrates vehicle network integration with vehicle body lateral vibration energy detection, dynamically controlling and outputting the configuration parameters of the grease spraying commands based on different operating conditions. This real-time adaptation to the actual needs of locomotives and rolling stock achieves precise control of the grease spraying commands, has wide applicability, reduces data computation and equipment maintenance costs, improves control efficiency and wheel flange lubrication effect, and ensures driving safety while effectively implementing wheel flange lubrication.

[0073] It is worth noting that, Figure 1 The scenario shown for vehicle wheel flange lubrication control is also applicable to Figure 2 or Figure 3 The methods for controlling the lubrication of vehicle wheel flanges will not be elaborated here.

[0074] The following uses a controller as an example to illustrate the implementation process of the vehicle wheel flange lubrication control method provided in this embodiment of the invention. It is understood that the execution subject of the vehicle wheel flange lubrication control method provided in this embodiment of the invention includes, but is not limited to, a controller.

[0075] Figure 2 A flowchart of a vehicle wheel flange lubrication control method provided in an embodiment of the present invention is shown below. Figure 2 As shown, the method includes:

[0076] Step 101: Obtain the vehicle's operating data indicators and operating condition indicators.

[0077] Step 102: Based on the running data indicators and the pre-generated standard data indicators, generate a grease spraying command with configured grease spraying parameters.

[0078] In this embodiment of the invention, the operational data indicators include vehicle acceleration, and the standard data indicators include the vibration midpoint value.

[0079] Step 103: Based on the operating condition indicators, perform logical processing on the grease spraying configuration parameters, and control the output of grease spraying commands under different operating conditions according to the logically processed grease spraying configuration parameters, so as to drive the solenoid valve to spray lubricating grease onto the vehicle wheel flange.

[0080] The technical solution provided in this invention involves acquiring vehicle operating data indicators and operating condition indicators; generating grease spraying commands with configured grease spraying parameters based on the operating data indicators and pre-generated standard data indicators; logically processing the grease spraying configuration parameters according to the operating condition indicators; and controlling the output of grease spraying commands under different operating conditions according to the logically processed grease spraying configuration parameters to drive the solenoid valve to spray lubricating grease onto the vehicle wheel flange. This integrates vehicle network integration with vehicle body lateral vibration energy detection, dynamically controlling and outputting the configuration parameters of the grease spraying commands based on different operating conditions. This real-time adaptation to the actual needs of locomotives and rolling stock achieves precise control of the grease spraying commands, has wide applicability, reduces data computation and equipment maintenance costs, improves control efficiency and wheel flange lubrication effect, and ensures driving safety while effectively implementing wheel flange lubrication.

[0081] Figure 3 A flowchart of another vehicle wheel flange lubrication control method provided in an embodiment of the present invention is shown below. Figure 3 As shown, the method includes:

[0082] Step 201: Obtain the vehicle's operating data indicators and operating condition indicators.

[0083] In this embodiment of the invention, each step is executed by the controller.

[0084] In this embodiment of the invention, the operating data indicators include, but are not limited to, vehicle acceleration and operating speed; the operating condition indicators include, but are not limited to, whether the vehicle is in an emergency braking state, whether it is in a sand-spreading state, whether it is in a rapid braking state, whether there is a high-level braking command, and whether there is a high-level traction command.

[0085] Specifically, upon receiving a start-up signal transmitted via hardwired transmission from the vehicle, indicating that the vehicle has begun operation, the system acquires the vehicle's operational data and condition indicators according to a preset time period. In practice, the system collects the vehicle's acceleration a = {a1, a2, a3, ..., a...} per unit time at a preset acquisition frequency. N}

[0086] For example: the sampling frequency is 1kHz, and the sampling unit time is 0.256s, that is: the vehicle acceleration collected by the accelerometer per unit time is a={a1,a2,a3,...,a...} 256}

[0087] It is worth noting that the preset time period can be set according to actual needs to achieve real-time acquisition of vehicle operation data indicators and operating condition indicators.

[0088] Furthermore, when a start-up signal is received from the vehicle via hardwired transmission, it indicates that the vehicle has started running and begun accumulating driving time and distance, which will then serve as one of the criteria for determining the output of the grease spraying command.

[0089] Step 202: Generate vehicle vibration energy value based on vehicle acceleration and vibration midpoint value.

[0090] In this embodiment of the invention, the magnitude of the acceleration value reflects the magnitude of the interaction force between the wheelset and the rail, and its standard deviation per unit time reflects the magnitude of the vibration energy of the interaction between the wheelset and the rail. By detecting and calculating this energy value, the contact wear state between the wheel flange and the rail can be determined.

[0091] Specifically, through The vehicle acceleration and vibration midpoint values ​​are calculated to generate the vehicle vibration energy value. Here, E represents the vehicle vibration energy value, and a... i Let N be the acceleration of the i-th vehicle collected per unit time, and N be the number of vehicle accelerations collected per unit time. This is the value at the midpoint of the vibration.

[0092] In this embodiment of the invention, the vibration midpoint value This refers to the acceleration values ​​collected by the controller when the vehicle is stationary on a straight track. As an optional option, the vibration midpoint value... The value is 2048.

[0093] Step 203: Generate a grease spraying command with grease spraying configuration parameters based on the vehicle vibration energy value.

[0094] In this embodiment of the invention, when the locomotive and rolling stock are running on a straight section, the wheel flanges and rails are basically not in contact, and the lateral vibration energy of the car body is low. A grease spraying command with a large time interval Δt2 or a large distance interval Δs2 is executed, that is, the interval between two consecutive sprays is Δt2 or Δs2. When the locomotive and rolling stock are running on a curved section, especially on a small curve, the wheel flanges and rails are in contact and friction, and the lateral vibration energy of the car body is large. When the detected energy value is greater than the threshold, a grease spraying command is executed immediately. After that, the interval between two consecutive sprays is executed with a grease spraying command with a small time interval Δt1 or a small distance interval Δs1.

[0095] In this embodiment of the invention, step 203 specifically includes:

[0096] Step 2031: Determine whether the vehicle vibration energy value is greater than or equal to the preset energy threshold. If yes, proceed to step 2032; otherwise, proceed to step 2035.

[0097] In this embodiment of the invention, the energy threshold is preset according to actual needs, and this embodiment of the invention does not limit it. As an optional solution, the energy threshold value is 35.

[0098] In this embodiment of the invention, if the vehicle vibration energy value is greater than or equal to the preset energy threshold, it indicates that the locomotive is running on a curved section, and the wheel flange is in contact with the rail. It is necessary to spray grease at a small distance interval or time interval, and continue to execute step 2032; if the vehicle vibration energy value is less than the energy threshold, it indicates that the locomotive is running on a straight section, and the wheel flange is basically not in contact with the rail. In order to ensure driving safety, it is necessary to spray grease at a large distance interval or time interval, and continue to execute step 2035.

[0099] Step 2033: Determine the configuration parameters for the first grease spray.

[0100] In this embodiment of the invention, if it is necessary to perform grease spraying at a smaller distance interval or time interval, a first grease spraying configuration parameter is set according to actual needs. The first grease spraying configuration parameter includes a first time interval Δt1 or a first distance interval Δs1.

[0101] As an alternative, the first time interval Δt1 is 6 seconds (s), and the first distance interval Δs1 is 100 meters (m).

[0102] Step 2034: Generate a liposuction command configured with the first liposuction configuration parameters based on the first liposuction configuration parameters. This step ends here.

[0103] In this embodiment of the invention, a liposuction command is configured according to the first liposuction configuration parameters, and a liposuction command configured with the first liposuction configuration parameters is generated. Specifically, if the liposuction command is configured according to a first time interval, then the liposuction command is output according to the first time interval; if the liposuction command is configured according to a first distance interval, then the liposuction command is output according to the first distance interval.

[0104] Step 2035: Determine the configuration parameters for the second grease spray.

[0105] In this embodiment of the invention, if it is necessary to perform grease spraying at a larger distance interval or time interval, a second grease spraying configuration parameter is set according to actual needs. The second grease spraying configuration parameter includes a second time interval Δt2 or a second distance interval Δs2.

[0106] As an alternative, the second time interval Δt2 is 120 seconds (s), and the second distance interval Δs2 is 2000 kilometers (km).

[0107] It is worth noting that the configuration parameters for the first grease spray are smaller than those for the second grease spray.

[0108] Step 2036: Obtain the running interval value.

[0109] In this embodiment of the invention, the operating interval value includes a driving time interval or a driving distance interval. It is worth noting that the operating interval value is obtained in real time through the vehicle network.

[0110] Specifically, if the second grease spray configuration parameter is the second time interval Δt2, the running interval value is the driving time interval, and the driving time interval is the difference between the time of the last grease spray command and the current time. If there is no time of the last grease spray command, then the driving time interval is the difference between the vehicle running time and the current time.

[0111] Specifically, if the second grease spray configuration parameter is the second distance interval Δs2, the running interval value is the driving distance interval, which is the distance between the position where the grease spray command was last executed and the current position, that is, the driving distance from the time when the grease spray command was last executed to the current time. If there is no position where the grease spray command was last executed, then the driving distance interval is the driving distance from the start of the vehicle to the current time.

[0112] Step 2037: Determine whether the running interval value is greater than or equal to the second grease spraying configuration parameter. If yes, proceed to step 2038; otherwise, proceed to step 2036.

[0113] In this embodiment of the invention, if the second grease spraying configuration parameter is the second time interval Δt2, and the running interval value is the driving time interval; if the driving time interval is greater than or equal to the second time interval, it indicates that the conditions for outputting the grease spraying command are met, and step 2038 is continued; if the driving time interval is less than the second time interval, it indicates that the conditions for outputting the grease spraying command are not met, and step 2036 is continued.

[0114] In this embodiment of the invention, if the second grease spraying configuration parameter is the second distance interval Δs2, and the running interval value is the driving distance interval; if the driving distance interval is greater than or equal to the second distance interval, it indicates that the conditions for outputting the grease spraying command are met, and step 2038 is continued; if the driving distance interval is less than the second distance interval, it indicates that the conditions for outputting the grease spraying command are not met, and step 2036 is continued.

[0115] Step 2038: Generate a liposuction command configured with the second liposuction configuration parameters according to the second liposuction configuration parameters.

[0116] In this embodiment of the invention, a liposuction command is configured according to the second liposuction configuration parameters, and a liposuction command configured with the second liposuction configuration parameters is generated. Specifically, if the liposuction command is configured according to the second time interval, then the liposuction command is output according to the second time interval; if the liposuction command is configured according to the distance interval, then the liposuction command is output according to the second distance interval.

[0117] Step 204: Determine whether the system is in an emergency braking state, a sand-spreading state, or a rapid braking state. If yes, proceed to step 205; otherwise, proceed to step 206.

[0118] In this embodiment of the invention, if the vehicle is in one of the following states: emergency braking, sand spreading, or rapid braking, it indicates that the vehicle is in a state where the wheels and rails are prone to slippage. If a grease spraying command is issued at this time, even a small amount of grease splashing onto the tread may aggravate the slippage. To ensure driving safety, grease spraying is not performed, and step 205 is continued. If the vehicle is not in an emergency braking, sand spreading, or rapid braking state, it indicates that the vehicle is in a normal operating condition. Further judgment is made, and step 206 is continued.

[0119] Step 205: Stop output and reset grease spraying command, then continue executing step 201.

[0120] In this embodiment of the invention, the output of the grease spraying command is stopped, the grease spraying command is reset, and step 201 is executed again.

[0121] Step 206: Based on the operating speed, determine whether the vehicle is in the low-speed operating zone. If yes, proceed to step 207; otherwise, proceed to step 209.

[0122] In this embodiment of the invention, if the operating speed is within a preset low-speed range, it indicates that the vehicle is in the low-speed operating range, and step 207 is executed; if the operating speed is not within the preset low-speed range, it indicates that the vehicle is not in the low-speed operating range and is in normal operating condition, and step 209 is executed.

[0123] In this embodiment of the invention, the low-speed range can be set according to actual needs, and this embodiment of the invention does not limit it. As an optional solution, the low-speed range is an operating speed v less than or equal to 30 km / h (v ≤ 30 km / h).

[0124] Step 207: Determine whether either a high-level braking command or a high-level traction command exists. If yes, proceed to step 208; otherwise, proceed to step 209.

[0125] In this embodiment of the invention, if the vehicle is in a low-speed operating zone and a high-level braking command is present, the single-time grease injection time needs to be reduced to achieve a single-time grease reduction command, and step 208 continues; if the vehicle is in a low-speed operating zone but there is no high-level braking command, it indicates that the vehicle is in normal operating condition, and step 209 continues. For example, when the vehicle is in a low-speed zone (v≤30km / h) and the braking level of the high-level braking command is greater than 70%, a single-time grease reduction command is achieved.

[0126] In this embodiment of the invention, if the vehicle is in a low-speed operating zone and a high-level traction command is present, the single-time grease spraying time needs to be reduced to achieve a single-time reduced-volume grease spraying command, and step 208 continues; if the vehicle is in a low-speed operating zone but there is no high-level traction command, it indicates that the vehicle is in normal operating condition, and step 209 continues. For example, when the vehicle is in a low-speed zone with v≤30km / h and the traction level of the high-level traction command is greater than 70%, a single-time reduced-volume grease spraying command is achieved.

[0127] Step 208: Perform a single reduction on the liposuction configuration parameters according to the preset reduction standard to obtain the reduced liposuction configuration parameters, and control the output of liposuction commands according to the reduced liposuction configuration parameters. The process ends.

[0128] In this embodiment of the invention, the reduction standard can be set according to actual needs, and this embodiment of the invention does not limit it. As an optional solution, the reduction standard is a reduction of 1 second in the duration of grease spraying.

[0129] For example, if the reduction standard is to reduce the duration of fat spraying by 1 second, and the original duration of fat spraying is 2 seconds, then by performing a word reduction on the fat spraying configuration parameters according to the reduction standard, the fat spraying configuration parameters of the reduced fat spraying command executed this time will be configured with either the first fat spraying configuration parameter or the second fat spraying configuration parameter, and the duration of a single fat spraying session will be 1 second.

[0130] Furthermore, the reduced grease spraying command is output to drive the solenoid valve to spray grease according to the reduced grease spraying configuration parameters, thereby realizing reduced grease spraying for single wheel rim lubrication.

[0131] Step 209: Control and output the grease spraying command according to the grease spraying configuration parameters.

[0132] In this embodiment of the invention, if the vehicle is in normal driving condition, a grease spraying command is output according to the original grease spraying duration and the configured grease spraying parameters, driving the solenoid valve to spray grease according to the original grease spraying duration and the configured grease spraying parameters, thereby realizing rim lubrication grease spraying.

[0133] The controller parameter setting logic of this invention is simple. Users only need to set two parameters: a smaller first grease spraying configuration parameter and a larger second grease spraying configuration parameter. During initial setup, the first grease spraying configuration parameter can be as small as possible, and the second grease spraying configuration parameter can be as large as possible. This invention considers the overall operation of locomotives and rolling stock. Even if the parameters are not set appropriately, it can ensure that wheel flange lubrication will not aggravate or induce wheel slippage or freewheeling failures under special operating conditions, exhibiting high fault tolerance and further improving safety. The model representing wheel flange wear in this invention matches actual operating conditions, has a simple algorithm, and requires lower controller hardware configuration, which helps save costs. It can achieve less grease spraying when wheel flange wear is low and more grease spraying when wear is high, effectively reducing wheel flange wear while significantly reducing grease usage and further saving costs.

The user information in the embodiments of this application was obtained through legal and compliant means, and the acquisition, storage, use, and processing of user information have been authorized and agreed upon by the client.

[0135] The technical solution of the vehicle wheel flange lubrication control method provided in this invention involves acquiring vehicle operating data indicators and operating condition indicators; generating grease spraying commands with configured grease spraying parameters based on the operating data indicators and pre-generated standard data indicators; logically processing the grease spraying configuration parameters according to the operating condition indicators; and controlling and outputting grease spraying commands under different operating conditions according to the logically processed grease spraying configuration parameters to drive the solenoid valve to spray lubricating grease onto the vehicle wheel flange. This method integrates vehicle network integration with vehicle body lateral vibration energy detection, dynamically controls and outputs the configuration parameters of the grease spraying commands based on different operating conditions, and adapts to the actual needs of locomotives and rolling stock in real time. This achieves precise control of the grease spraying commands, has wide applicability, reduces data computation and equipment maintenance costs, improves control efficiency and wheel flange lubrication effect, and ensures driving safety while effectively implementing wheel flange lubrication.

If none of the indicators of whether the vehicle is in an emergency braking state, whether it is in a sand-spreading state, or whether it is in a rapid braking state are no, the vehicle is judged to be in a low-speed operating zone based on the operating speed. If yes, the vehicle is judged to be in a high-level braking command or a high-level traction command exists. If yes, the grease spraying configuration parameters are reduced once according to a preset reduction standard to obtain the reduced grease spraying configuration parameters, and the grease spraying command is controlled to be output according to the reduced grease spraying configuration parameters. If no, the grease spraying command is controlled to be output according to the grease spraying configuration parameters.
