Fig. 1 is a block diagram of a tread sweeping system according to an embodiment of the present invention, showing a tread sweeping control device 10 according to an embodiment of the present invention. As shown in fig. 1, the wheel tread surface cleaning system according to the embodiment of the present invention includes a tread surface cleaning device 50 installed corresponding to a wheel 990 of a railway vehicle 90, wherein a working surface of an abrasive block 530 of the tread surface cleaning device 50 is opposite to a wheel tread surface of the wheel 990, and when the tread surface cleaning device 50 is triggered to perform a tread surface cleaning operation, the abrasive block 530 acts on the wheel tread surface of the wheel 990 and generates friction with the wheel tread surface, so as to perform a trimming operation (abbreviated as a trimming operation) on the wheel tread surface of the wheel 990, maintain a relatively good adhesion state between the wheel 990 and a rail, and prevent the wheel tread from being scratched due to wheel slip.
Tread sweeping device 50 uses air cylinder 510 to controllably deliver power to the wheel tread of wheel 990 that causes abrasive segments 530 to act on the wheel tread, so that the air intake pressure inside air cylinder 510 can determine or influence the friction of abrasive segments 530 against the wheel tread during use of the tread sweeping device, and thus affect its sweeping, tacking, and contouring effects. Therefore, controlling the intake pressure of the cylinder 510 becomes one of the important aspects of friction control of the wheel tread.
It should be noted that the specific structure and/or type of tread surface cleaning device 50 used in the wheel tread surface cleaning system of the embodiment of the present invention is not limited, and even the installation manner of the tread surface cleaning device with respect to the rail vehicle 90 is not limited, and various types of existing tread surface cleaning devices with cylinder driving, and even various new types of tread surface cleaning devices with cylinder driving emerging from this application, can be used. Accordingly, the specific internal structure and/or operation of tread sweeping device 50 will not be discussed in detail herein.
The wheel tread surface cleaning system according to the embodiment of the present invention includes the wheel tread surface cleaning control device 10 provided specifically for the tread surface cleaning device 50, and the wheel tread surface cleaning control device 10 can control the intake pressure of the air cylinder 510 of the tread surface cleaning device 50, thereby controlling the friction between the grinding block 530 of the tread surface cleaning device 50 and the tread surface of the wheel 990. The wheel tread surface cleaning control device 10 may be provided for one tread surface cleaning device 50, and in another embodiment, may be provided for a plurality of tread surface cleaning devices 50 and may control the intake pressure of the plurality of tread surface cleaning devices 50 simultaneously and in parallel.
In one embodiment, the wheel tread cleaning control device 10 may be embodied in the form of a control box, which may be correspondingly mounted on or near the tread cleaning device 50, and may be provided integrally with the tread cleaning device 50; wheel tread sweeping control device 10 is arranged substantially independently of rail vehicle 90 and is dedicated to drive control of one or more tread sweeping devices 50; that is, tread sweep control device 10 operates substantially independently of other control systems or components of rail vehicle 90, e.g., changes in its internal adjustment settings do not substantially affect other control systems or components of rail vehicle 90, and the components used by tread sweep control device 10 are not used for drive control of other control systems or components of rail vehicle 90 other than tread sweep device 50 (e.g., brake air circuit control system 930 and/or brake air circuit control assembly 920).
Continuing with FIG. 1, tread sweeping control device 10 is comprised primarily of two major modules, namely, an air circuit control assembly 100 and an electrical circuit control section 200.
The air path control assembly 100 may be disposed corresponding to the air path 109 of the air cylinder 510 of the tread sweeping device 50, and for example, includes hardware such as switches disposed on the air path 109 and capable of influencing the air flow of the air path, and these switches may be electrically controlled or driven, thereby facilitating automatic control of air intake of the air cylinder; fig. 2 is a schematic diagram illustrating the structure of the air circuit control assembly 100 of the apparatus 10 for controlling tread sweeping according to an embodiment of the present invention.
The circuit control portion 200 may be implemented in the form of, for example, a circuit board, and is coupled to some components (e.g., the intake solenoid valve 104 and the exhaust solenoid valve 105) of the air circuit control assembly 100 that can be controlled electrically, and the circuit control portion 200 may control one or more components (e.g., the intake solenoid valve 104 and the exhaust solenoid valve 105) of the air circuit control assembly 100 to control the intake pressure of the cylinder 510, for example, to dynamically control the intake pressure of the cylinder 510 at a predetermined pressure value.
As shown in FIG. 2, in one embodiment, the air supply of the air circuit 109 of the air circuit control assembly 100 is accessed from the main air duct 910 of the rail vehicle 90, it being understood that the main air duct 910 may also provide an air supply for other systems or components of the rail vehicle 90, such as for example, a brake system, etc. The air pressure of the air supply of manifold 910 is generally higher than the inlet air pressure required by tread sweeping device 50. A front-end ball valve 101 may be disposed upstream of the gas path 109, and the front-end ball valve 101 may be used to switch the activation and deactivation of the gas path 109; the gas circuit 109 is activated when the front end ball valve 101 is opened, and the gas circuit 109 is deactivated when the front end ball valve 101 is closed, and the valve body of the front end ball valve 101 and the air of the downstream gas circuit are emptied.
As shown in fig. 2, the air path control assembly 100 further includes a safety valve 102 disposed on the air path 109, and the safety valve 102 may be disposed downstream of the front end ball valve 101, and may be configured to ensure safety of an air source (e.g., the main air duct 910) connected to the air path 109, so as to protect air pressure of the main air duct 910 of the rail vehicle 90, that is, to implement total air under-pressure protection. Specifically, when the pressure of the main air duct 910 is higher than the safety threshold set in the corresponding safety valve 102, the safety valve 102 is fully opened, and the air source of the main air duct 910 flows downstream of the safety valve 102; if the pressure of the total air duct 910 is lower than the safety threshold, the safety valve 102 is closed to ensure stable pressure of the rail vehicle 90, so that the total air abnormality of the rail vehicle caused by the system failure of the tread cleaning device 50 can be avoided, and the running safety can be ensured.
Continuing with FIG. 2, air circuit control assembly 100 further includes a pressure relief valve 103 disposed in air circuit 109. pressure relief valve 103 may be disposed downstream of ball valve relief valve 102. in view of the potential for excessive pressure in the incoming total wind, pressure relief valve 103 may be used to substantially reduce the wind pressure of the incoming wind source to a substantially desired inlet pressure range (e.g., a certain inlet pressure range) for tread sweeping device 50. The pressure reducing valve 103 may be implemented by a controllable valve body.
It should be noted that the tread cleaning device 50 may be accompanied by the change of the requirement for the air inlet pressure during the use, for example, the tread cleaning and the tread contact pressure may show the curve fluctuation change, which requires the introduction of the solenoid valve of the following embodiment to adjust the air inlet pressure in real time to control the pressure when the grinding block contacts with the tread
As shown in fig. 2, the air path control assembly 100 further includes an intake solenoid valve 104 and an exhaust solenoid valve 105, the intake solenoid valve 104 and the exhaust solenoid valve 105 are controlled by the circuit control portion 200, that is, the control output signal output by the circuit control portion 200 can control the intake solenoid valve 104 and the exhaust solenoid valve 105 to switch states. It will be appreciated that the intake solenoid valve 104 and the exhaust solenoid valve 105 may be implemented by other types of controllable valve bodies. By arranging the positions of the intake solenoid valve 104 and the exhaust solenoid valve 105 in the gas path 109, the intake pressure of the cylinder 510 can be made to rise when the intake solenoid valve 104 is open and the exhaust solenoid valve 105 is closed, and the intake pressure of the cylinder 510 can be made to fall when the intake solenoid valve 104 is closed and the exhaust solenoid valve 105 is open. The front end ball valve 101, the relief valve 102, and the pressure reducing valve 103 described above are arranged upstream of the intake solenoid valve 104 and the exhaust solenoid valve 105 on the gas path.
To facilitate manual control (e.g., in the event of a malfunction), a first ball valve 107 and a second ball valve 108 may be further provided in the gas circuit control assembly 100 as shown in fig. 2, specifically, the first ball valve 107 is provided in parallel with the inlet solenoid valve 104 on an internal parallel branch of the gas circuit 109, and the second ball valve 108 is provided in series with the outlet solenoid valve 105 on an outlet branch of the gas circuit 109. First ball valve 107 and second ball valve 108 may be used to manually control the inlet pressure of tread sweeping device 50 in a neutral state; the inflation operation of the tread surface cleaning device 50 is performed when the first ball valve 107 is opened and the second ball valve 108 is closed, and the exhaust gas relief operation of the tread surface cleaning device 50 is performed when the first ball valve 107 is closed and the second ball valve 108 is opened.
As further shown in FIG. 2, pressure sensor 106 may also be located in air circuit control assembly 100, and pressure sensor 106 may be located in air circuit 109 near the inlet of air cylinder 510 so that pressure sensor 106 can be used to detect the magnitude of the inlet air pressure of tread sweeping device 50 in real time. The pressure sensor 106 may be coupled (e.g., wired) to the circuit control portion 200 such that air pressure information detected by the pressure sensor 106 may be fed back to the circuit control portion 200.
In one embodiment, the air path control assembly 100 may be independently disposed relative to other air path control assemblies on the rail vehicle 90 (e.g., the brake air path control assembly 920 disposed in correspondence with the brake system), and the other air path control assemblies and the air path control assembly 100 may share the air source on the rail vehicle 90, but they do not substantially interfere or affect the air path control of the air paths in which each other is disposed. Therefore, when maintenance or debugging operations and the like need to be performed on some parts of the air path control assembly 100, the air path control assembly is easily isolated from other air paths on the rail vehicle 90, and the operations such as maintenance or debugging operations and the like are simplified without excessively considering the requirements of other air paths on the rail vehicle 90 and the influence on the control of other air paths on the rail vehicle 90.
Fig. 3 is a schematic diagram showing the basic operation principle of the air passage control assembly of the apparatus for controlling cleaning of a tread surface of a wheel according to an embodiment of the present invention.

Fig. 4 is a schematic diagram showing a configuration of a circuit control unit of the tread surface cleaning control device according to the embodiment of the present invention. As shown in fig. 4, wheel tread sweeping control apparatus 10 may further include speed detection means 301 for detecting and acquiring speed-related information of wheel 990 or rail vehicle 90; the speed detection means 301 may be embodied as an accelerometer 301, which may be disposed corresponding to the wheels 990 of the tread sweeping device 50 so that the speed related information of the railway vehicle 90 may be sensed and fed back to the circuit control portion 200. In one embodiment, speed detection component 301 is dedicated to tread surface cleaning device 50, such that circuit control unit 200 dedicated to tread surface cleaning device 50 need not obtain speed-related information from other control systems, such as rail vehicle 90, reducing the association of circuit control unit 200 with other control systems of rail vehicle 90, and facilitating independent control of the vehicle tread surface cleaning system itself relative to rail vehicle 90.
As shown in fig. 4, in an embodiment, the main body of the circuit control part 200 may be implemented by a programmable processing device, for example, in the form of a control board 240. The control board 240 may be provided with a PID (proportional-integral-derivative) controller 241 and a solenoid valve driving circuit 242. The circuit control portion 200 may further include a power management module 210, and the power management module 210 may provide corresponding dc power for each module (e.g., the control board 240) in the circuit control portion 200, for example, the power management module 210 may access a dc power of, for example, 110V from, for example, a body dc power 940 of the rail vehicle 90, and the power management module 210 may perform voltage conversion on the dc power of 110V and output 24V dc power suitable for supplying power to the circuit control portion 200.
As shown in fig. 4, the circuit control unit 200 may further include a pressure input module 220, the pressure input module 220 receives air pressure information from the pressure sensor 106, the air pressure information reflects the current intake pressure of the cylinder 510, and the pressure input module 220 may perform, for example, signal conversion processing on the air pressure information and further output the air pressure information to the control board 240, for example, to the PID controller 241. The circuit control portion 200 may further include a speed calculation module 230, and the speed calculation module 230 may receive the speed related information from the speed detection unit 301 and calculate corresponding acceleration and speed magnitude information, and output the acceleration and speed magnitude information to the control board 240, for example, to the PID controller 241.
In one embodiment, the velocity calculation module 230 may specifically apply the detected acceleration of the rail vehicle 90 according to the following relation (1)aIntegral calculation is carried out to obtain the current speedV：
Wherein the content of the first and second substances,V(t) Indicates the speed of the rail vehicle 90, a: (t) Indicating the detected acceleration of the rail vehicle 90,trepresenting time.
Control board 240 can determine the driving state of rail vehicle 90 (e.g., whether it is a stopped state, the speed range, the magnitude of acceleration, etc.) based on the acceleration and the magnitude of speed information input from speed calculation module 230, and can determine the operation logic of tread surface cleaning device 50.
The circuit control portion 200 (e.g., the control board 240) may be configured to generate control output signals for controlling one or more components (e.g., the intake solenoid valve 104, the exhaust solenoid valve 105) of the air circuit control assembly 100 based on the feedback input air pressure information and the speed related information (e.g., acceleration and speed magnitude information) to adjust the current intake air pressure to be substantially maintained at a predetermined pressure value corresponding to the respective speed condition of the wheel or rail vehicle 90.
It should be noted that the corresponding speed condition of the wheel 990 or the rail vehicle 90 may be determined by the speed-related information detected by the speed detecting part 301; the predetermined pressure value under a certain speed condition can be reasonably determined in advance, for example, a reasonable intake pressure value under different speed conditions (based on feedback cleaning effect as a judgment standard) is obtained through a limited number of tests and is taken as a corresponding predetermined pressure value under the speed condition. The correspondence between different speed conditions of the wheel or rail vehicle and different predetermined pressure values may be pre-configured in the PID controller 241 and may be recalled during the calculation process. The personalized corresponding relation can be obtained for different track lines, even different types of track vehicles, even different geographies or climatic conditions and the like, so that the personalized and relatively more reasonable corresponding relation is set or configured according to the requirements on tread friction under different conditions, and the control of the air inlet pressure is facilitated more reasonably. The concrete expression form of the above correspondence relationship is not restrictive (for example, it may be a table or the like).
The PID controller 241 may write a corresponding PID algorithm in advance to implement closed-loop control according to the fed-back air pressure information, and the PID controller 241 determines a predetermined pressure value corresponding to the velocity-related information according to the correspondence relationship based on the received velocity-related information and compares the air pressure information with the determined predetermined pressure value to generate a control output signal. Generating a control output signal for controlling the air intake solenoid valve 104 to be opened and the air exhaust solenoid valve 105 to be closed when the detected air pressure information of the air cylinder 510 is lower than a predetermined pressure value corresponding to the current speed condition (e.g., the speed of the rail vehicle 90) of the wheel 990, and generating a control output signal for controlling the air exhaust solenoid valve 105 to be opened and the air intake solenoid valve 104 to be closed when the detected air pressure information of the air cylinder 510 is higher than the predetermined pressure value corresponding to the current speed condition (e.g., the speed of the rail vehicle 90) of the wheel 990; therefore, the air inlet pressure of the air cylinder 510 can be stabilized at corresponding preset pressure values under different vehicle speeds, tread friction can be controlled according to different working conditions of the railway vehicle, and the tread sweeping effect can be optimized. Moreover, for example, by adjusting the corresponding PID parameters of the PID controller 241, the preset pressure values corresponding to different speed conditions can be conveniently adjusted and set, the requirements of achieving the optimized tread friction effect under different track lines, different environmental conditions and the like can be met, and the wheel tread cleaning system is convenient to maintain after being installed to adjust and optimize the tread cleaning, adhesion and shape modification effects.
Continuing with FIG. 4, a solenoid driver circuit 242 is coupled to an output of the PID controller 241, and the solenoid driver circuit 242 may receive the control output signal from the PID controller 241 and generate a control output signal suitable for driving the intake solenoid valve 104 and the exhaust solenoid valve 105 based on the control output signal. The output terminal of the solenoid valve driving circuit 242 is connected to the intake solenoid valve 104 and the exhaust solenoid valve 105, and the intake solenoid valve 104 and the exhaust solenoid valve 105 are controlled by control output signals outputted therefrom.
It should be noted that the predetermined pressure value may be a specific pressure value, and in some embodiments, the predetermined pressure value may also represent a pressure interval (e.g., a relatively small pressure interval), or the predetermined pressure value may also be dynamically changed, for example, according to a predetermined pressure curve, and the predetermined pressure value represents a point on the predetermined pressure curve.
Continuing with FIG. 4, circuit control 200 is disposed generally independently of rail vehicle 90 as a whole and is dedicated to one or more tread sweeping devices 50; for example, the circuit control portion 200 may operate independently from other control systems of the rail vehicle 90 (e.g., the brake gas circuit control system 930), and the circuit control portion 200 has little or substantially negligible effect on the other control systems of the rail vehicle 90 when operating or being adjusted; meanwhile, the circuit control unit 200 is not used to control other systems or components of the railway vehicle 90 other than the tread surface cleaning device 50. Thus, during the installation, debugging or maintenance, overhaul or adjustment of the tread surface cleaning device 50, the adjustment of the circuit control unit 200 can be performed by considering only the tread surface cleaning requirement, that is, it is not necessary to consider the whole tread surface cleaning requirement in the whole system of the whole railway vehicle 90 (because of the system complexity of the railway vehicle 90, the traditional air intake control of the tread surface cleaning device 50 is adjusted, the adjustment is limited and the consideration factors are many), it is not necessary to consider other system requirements such as the braking system, etc., it is beneficial to simplify the friction control of the tread surface cleaning device 50, greatly reduce the workload of the supplier of the wheel tread surface cleaning control system, for example, when the problem that the condition of the wheel is not obviously improved after the abnormal abrasion, cleaning, adhesion and modification of the grinding block is faced, a certain supplier body of the wheel tread sweeping control system is apt to quickly come up with corresponding adjustment solutions and also to easily carry out corresponding maintenance and optimization operations.
It should be noted that physically mounting on the rail vehicle 90, simply accessing the total wind and/or dc power from the rail vehicle 90, may not be understood as the "substantially independent arrangement from the rail vehicle" of the above embodiment.
Fig. 5 is a schematic view showing the operating principle of the wheel tread cleaning control device according to the embodiment of the present invention, and fig. 6 is a schematic flow chart showing the wheel tread cleaning control method according to the embodiment of the present invention. The following describes an operation principle 100 of a wheel tread surface cleaning control method and a wheel tread surface cleaning control device according to an embodiment of the present invention with reference to fig. 5 and 6.
First, in step S610, speed-related information of the rail vehicle (for example, speed and speed magnitude information calculated by the speed calculation module 230) is received, and a predetermined pressure value under a corresponding speed condition can be determined based on the speed-related information.
In this step, a corresponding predetermined pressure value can be determined based on the speed-related information obtained by the current feedback according to the corresponding relationship between different speed conditions and different predetermined pressure values of the wheel or rail vehicle pre-configured in the PID controller 241, for example, and the predetermined pressure value reflects the reasonable intake pressure of the cylinder 510 that needs to be controlled to reach currently in the tread sweeping, adhesion increasing and shape modifying processes, so as to optimize or adjust the tread sweeping, adhesion increasing and shape modifying effects. It should be understood that, according to specific needs, the predetermined pressure value may correspond to a pressure interval, which may be a pressure value corresponding to a certain speed interval, and different corresponding relationships may be set or configured for the wheel tread sweeping systems installed on different rail vehicles 90; alternatively, the predetermined pressure value may be dynamically varied, for example, according to a predetermined pressure curve corresponding to a point on the predetermined pressure curve, and different predetermined pressure curves may be set or configured for different tread sweeping systems installed on the rail vehicle 90.
Further, step S620, performing pressure comparison between the determined predetermined pressure value and the currently detected intake pressure; for example, it is determined whether the currently detected intake air pressure is higher than a predetermined pressure value (i.e., step S631), and it is determined whether the currently detected intake air pressure is lower than the predetermined pressure value (i.e., step S632). It will be understood that in the case where the predetermined pressure value is represented as a section, an intake pressure higher than the predetermined pressure value indicates that the intake pressure is higher than the upper limit of the section, and an intake pressure lower than the predetermined pressure value indicates that the intake pressure is lower than the lower limit of the section; in the case where the predetermined pressure value corresponds to one point on the predetermined pressure curve, the result of the above determination operation may also dynamically change as the predetermined pressure value changes.
If both of these determinations are "no", indicating that the current intake pressure of cylinder 510 is relatively consistent with the current speed condition, tread surface cleaning device 50 may continue to operate normally based on the previous intake control (i.e., step S650).
In the case where the determination of "yes" is made in step S631, the output control signal is generated to control the exhaust solenoid valve 105 to open and the intake solenoid valve 104 to close (i.e., step S641), so that the intake pressure of the cylinder 510 will be controlled to decrease.
If the determination of step S632 is yes, the output control signal is generated to control the exhaust solenoid valve 105 to close and the intake solenoid valve 104 to open and close (i.e., step S642), so that the intake pressure of the cylinder 510 is controlled to increase.
The above steps S631, S632, S641, S642 can be realized by PID control and solenoid valve drive control.
In step S660, the intake pressure of the tread sweeping device 50 is monitored, and the pressure information reflecting the intake pressure of the cylinder 510 is detected in real time by the pressure sensor 106, and then the monitored intake pressure is fed back to the PID controller 241, that is, the process returns to step S620, so that the intake pressure is adjusted to fall on the predetermined pressure value. Therefore, the above-described steps S620 to S660 realize the pressure closed-loop control as shown in fig. 5.
The wheel tread surface sweeping control process of the above embodiment can operate independently substantially independently of the control processes of other control systems (e.g., the brake air circuit control system 930) on the rail vehicle 90, and therefore, even if adjustment setting is required for, for example, correspondence between different speed conditions and different predetermined pressure values of the wheels or the rail vehicle, the other control systems on the rail vehicle 90 will not be substantially affected, and therefore, requirements of the other control systems on the rail vehicle 90 do not need to be considered, and it is relatively easy to optimize and adjust control parameters in the wheel tread surface sweeping control process, and the method is particularly suitable for rail vehicles with high safety requirements, complex systems, and high possibility that each system is originated from different suppliers or manufacturers.
It should be noted that, in other embodiments, the wheel tread sweeping control method further includes an adjustment updating step of the corresponding relationship between different speed conditions and different predetermined pressure values of the wheel or the rail vehicle, for example, by adjusting the PID parameters of the PID controller 241, the corresponding relationship can be adjusted very conveniently, so that in step S610, it can be determined that the predetermined pressure value suitable for the current rail line condition, for example, is obtained. It will be appreciated that by adjusting the PID parameters, other variables of the PID control process can also be conveniently adjusted.
It should be noted that the device or the method for controlling wheel tread cleaning according to the above embodiments can keep the intake pressure at a reasonable value during tread cleaning, and the tread cleaning effect is good, and can also be individually adjusted and set to achieve good tread cleaning, adhesion increasing and shape modifying effects under different track lines or working condition requirements.
