From progress Train Control and protection.Meanwhile driver's key signal at train II ends is in unactivated state, the isolation at II ends is touched
Point closure, the signal output of II ends ATP equipment are isolated.
Fig. 2 is the circuit diagram of ATP system isolating device 200 according to an embodiment of the invention.Such as institute in Fig. 2
Show, according to one embodiment of present invention, ATP system isolating device 200 of the invention include vehicle zero-speed contact C1, manually every
Leave and close K1, isolating device J1, safe input module M1, ATP the Safety output module M2 of driver's key switch K2, ATP and key
Spoon relay J2.
As mentioned above, ATP system of the invention isolation can be divided into isolation manually and driver's key isolates two kinds of sides
Formula.Both modes are described in detail separately below.
Manual isolation method
In the embodiment shown in Figure 2, manual isolation method by the vehicle zero-speed signalling contact C1 in Fig. 2, manually every
Leave and close K1 and isolating device J1 realizations.In fig. 2, one end (node 20) of vehicle zero-speed signalling contact C1 can be coupled to ATP
The power input of isolation of system device 200, the power input can be coupled to externally fed (for example, DC 110V).Vehicle zero
The other end (node 22) of fast signalling contact C1 is coupled to Manual isolation switch K1.Vehicle zero-speed signalling contact C1 can be coupled in itself
Sensor output is monitored to train speed or is capable of providing any suitable signal source of the status signal of the real-time speed of train.Car
Zero-speed signalling contact C1 may be configured such that train real-time speed when being zero, node 20 is turned on node 22, and work as train
When real-time speed is not zero, node 20 is set to be disconnected with node 22.
As an example, Manual isolation switch K1 can be provided in the driver's cabin of train one end on control panel can
The switch or knob being manually operated by driver.When switch or knob are pressed or rotate, Manual isolation switch K1 is correspondingly
Closure.Switch button can be reduced when being pressed or rotating again, and Manual isolation switch K1 is then correspondingly disconnected.It is as previously mentioned
, one end of Manual isolation switch K1 is coupled with node 22.The other end of Manual isolation switch K1 is then coupled to isolating device J1
Control contact.
In fig. 2, isolating device J1 is illustrated as being made of multiple isolating devices in parallel, for correspondingly generate multichannel every
The multiple-channel output for being used to isolate ATP equipment from output signal.It will be understood by those skilled in the art that isolating device can also be energy
Enough single integrated devices that required all control functions are provided.In one example, each in multiple isolating devices
Can be disconnecting relay J11- J1n.Certainly, it will be understood by those skilled in the art that disconnecting relay is an example,
Similar function, contactor, solid-state relay etc. can be realized using other devices.Adopting as shown in Figure 2
With multiple disconnecting relay J11- J1nIn the case of, the other end of Manual isolation switch K1 can be coupled to each isolating device
(disconnecting relay) J11- J1nControl contact 30a1- 30an。
Disconnecting relay J11There can be a pair of of output contact 24a1、24b1.One end (node of vehicle zero-speed signalling contact C1
22) it can be coupled to output contact 24a1, and the other end (node 20) is then coupled to output contact 24b1.As an example, when every
Gas-discharge relay J11Control contact 30a1During energization, contact 24a1With contact 24b1Conducting, so that by vehicle zero-speed signalling contact
C1 short circuits.It is noted that here for circuit space and cost is saved, disconnecting relay J1 make use of1A pair of of output contact
24a1、24b1, but can also realize similar function and control using a single relay.
Disconnecting relay J11Can also have a pair of of output contact 26a1、26b1.Contact 26a1ATP system can be also coupled to
The power input of isolating device 200, contact 26b1The safe input module M1 of ATP are then can be coupled to, as isolating device state
Signal.As an example, as disconnecting relay J11Control contact 30a1During energization, contact 26a1With contact 26b1Disconnect.
Disconnecting relay J11Can also have a pair of of output contact 28a1、28b1.This can be used as isolation output to output contact
Signal output is to Electric circuit.As an example, this pair of of output contact 28a1、28b1With another pair mentioned above
Output contact 26a1、26b1Form interaction relation.For example, work as relay J11Control contact 30a1During no power, contact 26a1With
Contact 26b1Conducting, and contact 28a1With contact 28b1Disconnect, and work as relay J11Control contact 30a1During energization, contact
26a1With contact 26b1Disconnect, and contact 28a1With contact 28b1Conducting.The interaction relation of this state mutual exclusion, which helps to improve, is
The safety and reliability of system, such as whether mutual exclusion determines whether line related is normal by examining the state of this two groups of contacts
Work.Contact 28a1With contact 28b1The suitable position that can be for example connected in Electric circuit be used for isolate (such as short circuit or
Bypass).
In manual isolation method as described above is realized, the highest priority of Manual isolation switch.As shown in Figure 2,
If Manual isolation switch K1 disconnect, not over driver's key produce isolation signals in the case of, no matter vehicle zero-speed
Whether contact C1 turns on, disconnecting relay J11Control contact 30a1Place will not all be powered, so that disconnecting relay J11's
Output contact (contact 24a1With contact 24b1, contact 28a1With contact 28b1) all in off-state, contact 26a1With contact
26b1In closure state.Contact 24a1With contact 24b1Disconnection causes vehicle zero-speed contact C1 not to be bypassed, contact 26a1With touching
Point 26b1Closure causes isolating device status signal for DC 110V (instruction ATP equipment is not isolated), contact 28a1With contact
28b1Disconnect same instruction ATP equipment not to be isolated, and its circuit coupled will not be caused to be short-circuited or bypass.
If Manual isolation switch K1 is closed, whether train is that " zero-speed " becomes precondition.More specifically, work as train
Real-time speed is zero, then vehicle zero-speed contact C1 will be switched on, so that the input power (DC of ATP system isolating device 200
Disconnecting relay J1 110V) will be input to via vehicle zero-speed contact C1 and Manual isolation switch K11Control contact 30a1,
That is disconnecting relay J11Control contact 30a1It will be powered, so that disconnecting relay J11Output contact (contact 24a1With touching
Point 24b1, contact 28a1With contact 28b1) all it is changed into conducting state, contact 26a1With contact 26b1It is off.Contact
24a1With contact 24b1Vehicle zero-speed contact C1 is caused to be bypassed.Contact 26a1With contact 24b1Disconnection causes isolating device
Status signal is 0 (instruction ATP equipment is isolated).Contact 28a1With contact 28b1The same instruction ATP equipment of conducting is isolated, and
And its circuit coupled is caused to be short-circuited or bypass.
Since vehicle zero-speed contact C1 is bypassed, even if this make it that hereafter train is not zero speed, input power still can be along section
Point 20, contact 24b1, contact 24a1, node 22, the path of Manual isolation switch K1 lead to contact 30a1, so that keep isolation after
Electric appliance J11Contact 28a1With contact 28b1Conducting state, so as to keep ATP equipment to be isolated.This state will protect always
Hold, until Manual isolation switch K1 is again off.After Manual isolation switch K1 is again off, above-mentioned node 20, contact
24b1, contact 24a1, node 22, the path disruption of Manual isolation switch K1 so that contact 30a1It is changed into no power, so that
Disconnecting relay J11Output contact (contact 24a1With contact 24b1, contact 28a1With contact 28b1) off-state is also returned to,
Contact 26a1With contact 26b1Return to closure state.
Fig. 3 is the method stream of the manual isolation method of ATP system isolating device 200 according to an embodiment of the invention
Cheng Tu.
Method starts from step 302, determines whether Manual isolation switch closes.If it is determined that Manual isolation switch patent
Close, then method advances to step 310, and ATP equipment will not be isolated, and method terminates.
If determining that Manual isolation switch closes at step 302, method advances to step 304, determines that ATP equipment is
It is no to be isolated.If it is determined that ATP equipment has been isolated, then method advances to step 308, and ATP equipment continues to be isolated, method
Terminate.If determining that ATP equipment is not isolated at step 304, method advances to step 306, determine train currently whether
For zero-speed.The speed if train is not zero, method advance to step 310, and ATP equipment will not be isolated, and method terminates.If
Step 306 place determines that train is zero-speed, then method advances to step 308, and ATP equipment is isolated, and method terminates.
Driver's key isolation method
Fig. 2 is returned to, as an exemplary embodiment, driver's key isolation method can be pacified by driver's key, ATP equipment
Full input module M1, ATP equipment safety output module M2 and isolating device J1 are realized.
One end (node 32) of driver's key switch K2 can be coupled to the power input (DC of ATP system isolating device 200
110V).The other end of driver's key switch K2 is coupled to the control contact 34 of key relay J2.Driver's key switch K2 can lead to
Train operator is crossed by train key insertion keyhole and rotation to be controlled.For example, when driver rotates key to activation shelves
When, driver's key switch K2 is switched on, when driver by key rotate to close shelves or and then extract key when, driver's key switch
K2 is disconnected.
As an example, key relay J2 can have a pair of output contact 36a, 36b and another pair output contact
38a、38b.Key relay J2 may be configured such that output contact 36a, 36b and output contact 38a, 38b export 2 tunnel mutual exclusions
Signal (being all the way height, another way is then to be low).Compared with signal all the way is only set, by exporting 2 tunnel mutexes, improve
The safety and reliability of key activation signal collection.If for example, only set 1 road signal, when signal is low level without
It is key un-activation also circuit malfunctions that method, which judges,.In contrast, due to there is provided 2 tunnel mutexes, when circuit is normal,
This 2 tunnel will show 10 or 01, if being shown as 00, can determine whether that wherein there occurs failure all the way.In the figure 2 example, key
Relay J2 be configured to when driver's key switch K2 be switched on when, contact 36a and contact 36b are switched on, and contact 38a and touch
Point 38b is disconnected.Conversely, when driver's key switch K2 is disconnected, contact 36a and contact 36b are disconnected, and contact 38a and
Contact 38b is switched on.The output signal of contact 36b and contact 38b is exported to ATP as key activation signal inputs safely mould
Block M1.
The safe input module M1 of ATP also gather the state of isolating device except gathering key activation signal.It is as previously mentioned
, the safe input module M1 of ATP can have one or more contacts 461-46n, for correspondingly receiving from isolating device J1's
Isolating device status signal is (for example, respectively from disconnecting relay J11-J1nContact 26b1-26bnIsolating device state letter
Number).In addition, the safe input module M1 of ATP may also include contact 44, for receiving the status signal from Manual isolation switch
(not shown).The safe input module M1 of ATP also have output contact 52, which is coupled to ATP Safety output modules M2's
Input contact 48.
ATP Safety output modules M2 also has a pair of of output contact 50a, 50b.Contact 50a is coupled to key relay J2
Output contact 38b, contact 50b is coupled to the control contact of isolating device J1.In the figure 2 example, contact 50b is coupled to often
One disconnecting relay J11- J1nControl contact 30a1- 30an.In one example, ATP Safety outputs module M2 can quilt
It is embodied as a relay, it is configured as input contact 48 when receiving high level, and output contact 50a, 50b conducting, make
Disconnecting relay J1 must be communicated to from the signal of contact 38b1- J1nControl contact 30a1- 30an, so that ATP is set
Standby output is isolated (as above described in conjunction with Figure 2).When input contact 48 receives low level, output contact 50a,
50b is disconnected so that the signal from contact 38b is disconnected with isolating device J1, and the output of ATP equipment is not isolated (ties as more than
Close Fig. 2 descriptions).In order to further improve the security and reliability, ATP Safety output modules M2 inside can be implemented as having
Redundant circuit, to ensure still work normally in line fault all the way.
The safe input module M1 of ATP can be generated based on the key activation signal and isolating device status signal that receive
ATP isolation control signals, and export the input contact 48 to ATP Safety output modules M2 via contact 52.People in the art
Member is it is appreciated that although in fig. 2, the safe input module M1 of ATP and ATP Safety output modules M2 are illustrated as two sseparated moulds
Block, but can also be by the two block combiners into an integration module.
Fig. 4 shows the driver's key according to an embodiment of the invention that can be performed by the safe input module M1 of ATP
The flow chart of isolation control method.
In step 402, the safe input module M1 collection driver's key signals of ATP and isolating device status signal.Then,
In step 404, just whether the safe input module M1 of ATP determine isolating device J1 based on the isolating device status signal collected
Often.If it is determined that isolating device J1 is abnormal, then method advances to step 420, the abnormal state prompting of generation isolating device.At this
In one embodiment of invention, as isolating device J1, more specifically, as disconnecting relay J11- J1nIn any one generation
Failure, the isolating device status signal of the contact from the power transfer relay will be just zero (or low level) so that ATP is defeated safely
The abnormality can be collected and provide prompt messages by entering module M1.The prompt messages can be presented to driver, together
When the isolating device abnormal state can be submitted to the control system of train, for recording and taking appropriate measures.For example, row
Vehicle control the auto by pass abnormal isolating device and can enable corresponding spare isolating device.Then, method advances to
Step 412, ATP equipment is not isolated, and method terminates.In this case, the safe input module M1 of ATP can not be to ATP safety
Output module output isolation signals (or output low level signal) so that ATP Safety output modules M2 is disconnected, the isolation of driver's key
Signal can not export, and ensure that the normal and effective output of isolation.
If determining that the state of isolating device is normal at step 404, method advances to step 406, determines that key is
It is no to be activated.If it is determined that key is in " inactive " state, then method advances to step 408, defeated to Safety output module M2
Go out isolation signals (high level) so that Safety output module M2 exports driver's key isolation signals.At this time, method advances to step
410, as shown in Fig. 2, disconnecting relay J11- J1nMust be electric, ATP equipment is isolated, and method terminates.
If determining that driver's key is in " activation " state at step 406, method advances to step 414, determines hand
Dynamic disconnecting switch state.As it would be appreciated, when key is in " activation " state, shows that this one end of train will be used as and advance
End, therefore the ATP equipment at the end should not be isolated.Therefore, if in step 414, the Manual isolation switch shape at the end is judged
State is disconnects, then the state is consistent with the intention that key status is embodied, then method advances to step 412, ATP equipment not by every
From method terminates.If in step 414, the Manual isolation switch state for judging the end is closure, then method advances to step
416, the state warning of generation Manual isolation switch confirms.The warning confirms to be displayed at the display screen of drivers' cab console
On, such as " whether local terminal ATP equipment Manual isolation switch currently should reset Manual isolation switch for closure, PLSCONFM ".In step
Rapid 418, driver can confirm the state of Manual isolation switch.It is not intended to grasp if driver recognizes that Manual isolation switch closure belongs to
Make, then driver, which can reset the Manual isolation switch, makes its disconnection, then method advances to step 412, and ATP equipment is not isolated, side
Method terminates.If for some cause specifics, driver does want to drive in the case where disconnecting local terminal ATP equipment (for example, department
Machine knows ATP device fails), then driver can confirm that the switch should be closure, and method advances to step 410, ATP equipment quilts
Isolation.
