Specific embodiment
Below in conjunction with attached drawing, detailed description of the preferred embodiments.It should be understood that this place is retouched
The specific embodiment stated is merely to illustrate and explain the present invention, and is not intended to restrict the invention.
Fig. 1 is the flow chart of according to embodiments of the present invention one motorcycle pantograph control method.As shown in Figure 1, this method
The following steps are included:
In the step s 100, when alternating current vehicle is main vehicle, when direct current Che Weicong vehicle, the pulse for controlling alternating current vehicle lifting bow is believed
Number be converted to the level signal of control direct current vehicle lifting bow.
In step s 200, and work as direct current Che Weizhu vehicle, when alternating current vehicle is from vehicle, the electricity of direct current vehicle lifting bow will be controlled
Ordinary mail number is converted to the pulse signal of control alternating current vehicle lifting bow.
Fig. 2 and Fig. 3 is the flow chart of the preferred embodiment of the step S100 and step S200 of embodiment one respectively.
As shown in Fig. 2, the step S100 of embodiment one can preferably include following steps:
In step S111-S112, the pulse signal rising edge of detection exchange car owner's vehicle sending.It can specifically include:
In step S111, the rising edge for the drop bow pulse signal that detection exchange car owner's vehicle issues, if the pulse signal
Rising edge it is effective, then further control direct current vehicle from vehicle drop bend, if the pulse signal rising edge is invalid, then it represents that currently not
It needs to control direct current vehicle and is dropped from vehicle and bent, and then carry out step S112.
In step S112, whether the rising bow pulse signal that detection exchange car owner's vehicle issues is effective, if rising bow pulse signal
Also the invalid control direct current vehicle that also do not need currently then is from vehicle rising bow for rising edge, if the rising bow pulse signal rising edge is effective, into
One step controls direct current vehicle from vehicle rising bow.
It should be noted that drop bow pulse signal rising edge and rising bow pulse signal that detection exchange car owner's vehicle issues rise
The sequencing on edge is not fixation, first carries out the sequence that step S111 carries out step S112 again herein, it is only for say
Bright, sequencing can arbitrarily be set in a control program.
In step S121-S122, when the pulse signal rising edge that exchange car owner's vehicle issues is effective, resets or set
Position rest-set flip-flop.
In step S121, when the drop bow pulse signal rising edge detected in step S111 is effective, set RS touching
Device is sent out, then control trigger exports low level in step S131, in step S151, sets direct current vehicle from the drop of vehicle and bends signal
For low level, bend to control its pantograph drop.
In step S122, when the rising bow pulse signal rising edge detected in step S112 is effective, set RS touching
Device is sent out, then control trigger exports high level in step S132, and then sets direct current vehicle from vehicle in step S152-S153
Rising bow signal high level, to control its pantograph rising bow.
The pantograph of locomotive generally comprises anterior arch and cantle at present, and anterior arch is usually closer from control room and control circuit,
And then farther out, therefore cantle is lower than anterior arch to the radiation effect of control circuit and control room to relative distance to cantle.In control by electricity
It, can be in order to reduce pantograph to the radiation effect of driver and operator in control circuit and control room when bending rising bow
Priority acccess control rises cantle, and when cantle is abnormal or cannot normally rise, control rises anterior arch.It therefore, in example 1, can be with
Preferably include step S140, when needing to control pantograph rising bow, detection cantle it is whether normal, if cantle normally if in step
S152 sets a liter cantle signal high level, to control a liter cantle, anterior arch signal is postponed in step S153 if cantle is abnormal
High level, to control a liter anterior arch.
As shown in figure 3, the step S200 of embodiment one can preferably include following steps:
In step S211-S212, the level signal of detection direct current car owner vehicle sending.It can specifically include:
In step S211, liter anterior arch or rise whether the level signal of cantle is high electricity that detection direct current car owner vehicle issues
It is flat, if so, whether detection alternating current vehicle has risen from the pantograph of vehicle in step S221, if from the pantograph of vehicle
It rises, does not then need further to operate, further control pantograph rises if pantograph is not raised configuration.
In step S212, whether the drop bow signal that detection direct current vehicle issues is low level, if so, in step S222
Whether detection alternating current vehicle has been fallen from the pantograph of vehicle, if the state that alternating current vehicle is not fallen from the processing of the pantograph of vehicle, is controlled
Make its drop bow.It should be noted that the sequencing of step S211 and step S212 are not fixation, it is only exemplary herein
Explanation.
In step S231-S232, when detecting that pantograph does not rise in step S221, or detected in step S222
When not falling to pantograph, enable signal impulse generator controls the signal pulse generator output pulse signal.
In step S241, when the drop for detecting that the main vehicle of direct current issues bends level signal, judge alternating current vehicle from Che Shou electricity
Whether bow has been fallen, and in the case where not falling from vehicle pantograph, output one rushes letter with the drop arculus that pulse temporal width is T
Number.
In step S242, when detecting the rising bow level signal that the main vehicle of direct current issues, judge alternating current vehicle from Che Shou electricity
Whether bow has risen, and in unrisen situation, exports the rising bow pulse signal that one-pulse time width is T.
Fig. 4 is the structure chart of according to embodiments of the present invention two motorcycle pantograph control system.As shown in figure 4, the system
Include: level switch module 100, for being main vehicle when alternating current vehicle, when direct current Che Weicong vehicle, the arteries and veins of alternating current vehicle lifting bow will be controlled
