Description
Technical field
The present invention relates to locomotive braking systems, and more particularly relate to the system that Brake pipe pressure is incrementally decreased
And method.
Background technology
In braking by grades or in other cases, the locomotive operator using pneumatically or electrically gas Pneumatic braking system is frequent
It needs that Brake pipe pressure is made to be slightly reduced minimum brake level or more.Control for brake on locomotive installation brake monitor
Bar is used as the man-machine interface of brake pipe control.Usually there is these levers the restriction for equalizing reservoir (ER) pressure to reduce
Setting position, which is the pilot pressure for brake pipe relay, and therefore provide be used for brake pipe (BP) pressure
Target level.For example, being generally designated as the handle position of " minimum " allows the braking for the minimum that can apply, and it is referred to as
The position of " full application of brake " provides normal full brake.
Reduce although operator is easy to get the brake pipe asked at " setting " position, such as " minimum " or " full system
It is dynamic ", but operator often wants to have to be just slightly larger than and be provided by " minimum " position to operate the system of train under certain conditions
Dynamic pipe (BP) pressure decrease amount.In these cases, operator generally has to carefully careful towards " full application of brake " position control stick
Ground is more than " minimum " position, to avoid excessive braking train.Although control-rod controls braking with contributing to operator's quicklook
Device is horizontal, but they do not allow operator desired by them between preconfigured " setting " position in some cases
Brake pipe (BP) pressure is controlled as accurately as possible like that.Another problem of Conventional braking systems is, due to operation rules or
The condition of Train Control so that the locomotive operator that Brake pipe pressure reduces must prevent frequently by independent release component is used
Only apply water brake.In these cases, operator must apply brake using both hands.These identical problems are deposited
It is in electronically controlled pneumatic (ECP) braking system.
Invention content
The present invention reduces system including incrementally brake pipe, and operator is allowed to generate equalizing reservoir (ER) desired value,
Without handle to be manually moved into inaccurate position.By using on man-machine control for brake interface button, switch or
Touch screen passes through input from another HMI device (button on such as locomotive or operator's display screen) to braking system or logical
Believe message, operator can ask being reduced incrementally for brake pressure, more accurately to select desired brake level.For example,
Then once operator has requested that " minimum " brake application, operator can reduce brake pipe pressure with a small amount of predetermined increments
Power it is expected with providing the more precise control to brake pressure without brake handle to be moved to operator's conjecture and will realize
Brake pressure expectation decrement position.Alternatively it is also possible to enable the braking area between " minimum " and " full application of brake "
BP reduction amounts in domain, to allow to occur this be reduced incrementally.

Curve graph.
Specific implementation mode
Referring now to the drawings, wherein identical reference numeral always shows identical component, in Fig. 1 it can be seen that braking
Controller 10, the brake monitor 10 include the system 12 for incrementally adjusting brake pressure.As shown in Figure 1.Operator is logical
Crossing single button 14 can use system 12, the button 14 that operator is allowed to be incremented by the case of without being braked by moving handle 16
Ground reduces brake pressure.It should be recognized by those skilled in the art that button 14 can be alternatively included on brake monitor 10
Switch, touch screen or combinations thereof, and be reduced incrementally and can complete in the following way：It is a series of to press lower button 14 for several times
Come complete it is a series of it is individually predetermined reduce or hold button 14 is pressed, while by key buffer by it is a series of incrementally
Reduce gradually and periodically recycle, until reaching level appropriate, subsequent operator's release button 14.Display 18 can be with
It is set as showing selected specific brake pressure to operator, or has button 14 as touch screen combination.
System 12 further includes the controller 22 in response to button 14, which implements the braking in locomotive braking system
The desired of pressure is reduced incrementally.For example, controller 20 is programmed to implement activity shown in Fig. 2.Controller 22 is distinguished
Receive the signal 24 and 26 of the position of the state and handle 16 that indicate button 14.When signal 26 indicates that handle 16 is in desired position
When setting in (such as " minimum "), controller 22 reads the state of button 14 by signal 24, and update ER goal pressures 28 simultaneously calculate
Desired ER goal pressures 30, then output order 32 is to realize that desired pressure reduces.It explains, controls in greater detail below
Device 22 processed can also reconfigure brake area range 34 to solve to be reduced incrementally using what button 14 selected by operator.When
When handle 16 moves back to " release " position, brake area is reset 36 and discharges existing brake pressure action 38.Although
Fig. 2 depicts the controller 22 for being arranged to implementation system 12 when handle 16 is in " minimum " position, but can use other
Position appropriate.
System 12 can be programmed to implement a variety of to be reduced incrementally scene.For example, in the first embodiment of the present invention,
It can be pressed for each desired increment with scheduled gain levels (such as single step-length between 0.5psi and 3psi)
Button 14 is primary.In another embodiment, button 14 can be pressed as described above, or can also be kept and be pressed, and be made
Feedback when proper ER targets are changed based on increment on display 18 shows ER targets.It can release button at any time
14, cause to be reduced incrementally the aspiration level for stopping and showing on display 18.Optionally, system 12 can be set to limit
The brake pipe reduction amount allowed by by lower button 14 is made, such as uses the possible maximum reduction amount of button 14 by having,
Such as only allow the additional reduction of 1psi, or reduction is limited to full application of brake brake pipe level.
In order to improve visibility, button 14 may include lighting device, be such as internally located in 14 rear portion of button or
Externally and be directed toward button 14 LED, with when system 12 may be used in (such as when handle 16 is moved to " minimum " position
When) illuminate button 14.Maximum it is incremented by when such as by the further mobile disabling system 12 of handle 16, or when reach scheduled
When formula reduction amount, lighting device can be closed.
When BP reduces by more than " minimum " application via system 12, and handle is still in " minimum " position, brake area model
It encloses or horizontal remaining BP reductions amount is reduced from present level to " full application of brake ".Therefore, the further movement of handle 16 will not
Pressure can be reduced, so as to cause " dead zone ", in " dead zone ", be generally understood as reducing the movement of the handle of Brake pipe pressure
It will not do so.This effect can see that wherein increment BP reductions further subtract Brake pipe pressure from minimum value in figure 3
Small 5psi, and therefore handle 16 will not cause from minimum position to a part for the movement of " full application of brake " position it is any additional
Pressure reduces, until the movement of the position of handle 16 is reduced beyond previously passed button 14 more than typical handle is relevant wherein
The point for the amount of being reduced incrementally realized.For example, if handle is placed in " minimum " position by operator, typically result in from just
Often reduce the BP of 7psi.If being reduced incrementally and being set to a psi, operator can then use button 14, such as
The BP of 12psi in total is reduced by pressing button 14 5 times from setting point pressure.If operator is then minimum (MIN) and complete
Brake moving handle half between (FS), and FS is to reduce away from normal 26psi, then handle movement above will in most of distance
Will not lead to any apparent variation of pressure because the movement from " minimum " to centre position just correspond to passed through by
Handle 16 is moved to " minimum " and then is reduced on the 12psi realized by lower button 14 5 times reduces for additional 5psi
One psi reduces (13psi in total).
In order to avoid this influence, optionally it is programmed in the software that system 12 can such as be run in controller 22,
To adjust the relevant reduction amount of movement with handle 16, to solve to be reduced incrementally by what button 14 was realized, appoint to eliminate
What " dead zone ".As shown in figure 4, braking range can be adjusted to change and the relevant pressure decrease amount of the movement of handle 16 so that
The entire moving range of handle 16 realizes that pressure reduces relative to the starting pressure and full application of brake pressure of reduction.For example, such as Fig. 4 institutes
To show, the mobile of handle 16 will reduce (although reducing with slower reduction speed) Brake pipe pressure in its entire moving range,
To make up the fact that the pressure when handle 16 is mobile from " minimum " first is less than the minimum pressure level not reduced.In other words
It says, movement of the handle 16 from minimum to full application of brake will be come with the rate of the reduction speed slightly less than in the case of no adjusting
Reduce pressure, to make up the fact that starting pressure is reduced by the operator of system 12, to allow the movement of handle 16 with
It realizes and reduces in its entire moving range.
In the embodiment of the system 12 readjusted automatically reduced with handle operating pressure, the present invention can be optional
Ground allows the automatic independent release of water brake, similar to the biography in the independent release for allowing the original application for brake
In system system like that.In this embodiment, in limiting time section (according to the adjustable timing of customer requirement), have individually slow
Solve original application operator can be directed to every time by lower button 14 make independent release activated limit the period (wanted also according to client
Ask adjustable timing).If operator's moving handle 16 can cancel independent release immediately.Therefore, controller 22 can be by
It is set as in response to from 14 received signal 24 of button, being operated with activating independent release within a predetermined period of time.System 12 can be with
In addition it is programmed to the basis execution (such as in using the formerly hand brakes application of the one or more of handle 16) in history
First independent release the automatic independent release of brake application is provided.Any automatic independent release also can be by programing system 12
Cancel, to cancel any automatic independent release in the case of operator's moving handle 16.
