Specific embodiment
With reference to the preferred embodiments of the present invention, present invention is described.Enumerate in explained below many concrete
Details.However, it will be appreciated by those skilled in the art that the present invention can not also adopt some or all in these details
And realize.In the case of having, known technology does not describe to avoid unnecessary obscuring.
In order to alert the situation for squeezing trouble, need to obtain the positional information of track switch, and when train is reversely sailed into
Early warning information during trouble.
Generally there are two kinds of positioning and antiposition in the position of track switch.In the context of the present invention, during described " positioning " refers to Fig. 1
It is straight to track open when position, and the position of " antiposition " when referring to that lateral rails are opened in Fig. 1.
New failure is introduced in order to prevent the indoor fixed, contact state of antiposition relay of collection, it is desirable to be able to from turn-out track
Pick out holding wire to obtain fixed, antiposition state in the circuit terminal of machine.Wherein, the quick-action switch of existing goat is provided with two
Individual terminal is respectively used to represent goat in positioning when representing fixed, antiposition position, wherein framing signal port output high level
Position, and represent that goat is in antiposition position during antiposition signal port output high level.
For example, in existing mounted goat, generally there are 4 row's terminals, the wherein the 1st, 4 row's terminals participate in motor
Forward and backward is controlled, and the 2nd, 3 row's terminals are only used as the expression of switch location.Therefore, for these mounted goats, can
Signal is picked out with the spare terminal arranged from the 2nd, 3 row's terminals to represent fixed, antiposition state, such as spare terminal of the 2nd row
High level represent position location, the spare terminal of the 3rd row represents antiposition position.For new goat, can be according to concrete
Using situation increase port exporting positioning, antiposition signal.
In addition it is also necessary to obtain signal when train reversely sails track switch into.For this purpose, as shown in Fig. 2 in the outside of track switch,
I.e. along Fig. 2, the downstream of the direction of arrow arranges wheel detector.The installation site of wheel detector can be according to concrete application
It is determined that, it is therefore preferable to apart from 15 meters of track switch or more, to obtain enough pre-warning times.
Wheel detector can be with existing any one suitable equipment.When wheel is after wheel detector, wheel is passed
Sensor will provide a Seize ACK message.Preferably, wheel detector can be with the interface that can directly drive external relay,
Signal conversion is carried out without other interface arithmetic units and occupancy or idle signal is directly given.
Preferably, in order to ensure fault-safety principle, the reliability of sensor is improved, it is straight on the outside of the heart rail of switch zones
Two sensors are respectively installed in stock and side strand road.Such as Fig. 2, respectively in straight each rail upwards for illustrating and on the side
On each rail, each setting arrange on wheel detector, that is, every rail a wheel detector.As such, it is possible to reduce receiving
To the probability of other factors interference, for example, personnel or other objects streak a wheel detector and cause wrong report.Further, exist
Directly keep at a certain distance away in rail direction to two wheel detectors on rail, such as 0.5 meter, can further reduce wrong report
Probability.In order in an embodiment of the present invention, two sensors being located on the rail of straight stock are respectively the first wheel-sensors
Device 10 and the second wheel detector 20, are located at two sensors on the rail of side stock and are respectively the 3rd wheel detector 30 and the
Four wheel detectors 40.
In order to process above-mentioned signal, take two computing devices using two, such as it is existing based on the two safety meters for taking advantage of two to take two
Calculation machine.In an embodiment of the present invention, when the signal transmission of the first and second wheel detectors 10,20 is to fail-safe computer, its
Judge whether the signal of first and second wheel detector is seizure condition signal.If first and second wheel-sensors
The signal of device is unanimously seizure condition signal, meanwhile, the switch location signal obtained from goat 100 is antiposition position signalling,
Then fail-safe computer sends warning signal to other external alarm equipment 300.In one example, can be sent out by CAN
Deliver to indoor track switch comprehensive monitor system.In other example, warning can be sent by live alarm equipment, for example, be warned
Lamp.
Similarly, for the signal of the third and fourth wheel detector, fail-safe computer 200 judges whether signal is and accounts for
Use status signal.If the signal of third and fourth wheel detector is seizure condition signal, while switch location signal
For framing signal, then fail-safe computer sends warning signal to other external alarm equipment.
As it was previously stated, an aspect of of the present present invention is related to a kind of crowded trouble monitoring device, as shown in Figure 3.Crowded Cha Jiancezhuanzhibao
A computing unit is included, in the present embodiment, the computing unit is one two fail-safe computer 200 for taking advantage of two to take two.It is such as front
Described, such fail-safe computer 200 is existing any suitable device, and which has logical sum computing function and can pass through
Commercial sources are obtained.
With reference to Fig. 3, the first input port 210 of the fail-safe computer 200 connects the framing signal port of goat 100
110, the second input port 220 connects the antiposition signal port 120 of goat 100.Meanwhile, the 3rd of the fail-safe computer 200 the
Input port 230 connects the first wheel detector 10, and the 4th input port 240 connects the second wheel detector 20；This is counted safely
5th input port 250 of calculation machine connects the 3rd wheel detector 30, and the 6th input port 260 connects the 4th wheel detector
40。
On the other hand, present invention additionally comprises squeezing the method that trouble is monitored, wherein：Obtain positioning and the antiposition position signalling of track switch
And judge the position of track switch；Obtain the Seize ACK message of at least one wheel detector, it is preferable that be respectively provided at same stock rail from two
Wheel detector on road on two rails obtains signal；When the signal of wheel detector is seizure condition, according to track switch
Position sends warning signal.
It should be noted that obtain switch location signal and judge and obtain wheel sensor signal, the step that both judge
There is no the order of fixation between rapid, can carry out simultaneously, it is also possible to successively carry out.
Above in conjunction with specific embodiment to the present invention have been described in detail.However, those skilled in the art can manage
, also there is some modifications and equivalent way within the scope of the invention in solution.Therefore, claim of the invention should be construed to bag
Include all such modifications and equivalent way.
