Specific embodiment
Below in conjunction with Figure of description and specific preferred embodiment, the invention will be further described, but not therefore and
It limits the scope of the invention.
As shown in Figure 1, in the neutral-section passing system of ground, train position sensor is set on ground, respectively J1, J2, J3 and
J4, when train passes through phase-separating section from left to right, i.e., positive direction of traffic, is into split-phase control using sensor J1, J3 and J4, J1
Processed, J3 is commutation control point, and J4 is individual-phase control point, first switch QF1, second switch QF2；When train from the right side to
When a left side passes through phase-separating section, i.e. train running in reverse direction direction is into individual-phase control point using sensor J1, J2 and J4, J4, and J2 is commutation control
Processed, J1 is individual-phase control point, first switch QF2, second switch QF1.Train pass through from left to right phase-separating section with from
Right-to-left is identical by the control principle of phase-separating section.
The passing neutral section control system of the prior art is only able to achieve train according to determining direction, once by phase-separating section, such as
In Fig. 1, train from left to right, or from the right side to the right side by phase-separating section, without supporting train to turn back back and forth operation in phase-separating section, and
In actual moving process, due to failure that may be present in train line, it is sometimes desirable to which train is turned back in phase-separating section.Such as Fig. 1 institute
Show, into explanation by taking train is run from left to right as an example, when because of line fault, train needs halt, and turn back and return back out hair
When station, train is possible to stop at any position in Fig. 1, then turns back and run to the left.It, can be with when just needing individual-phase control
It based on the state of train at an arbitrary position, is flexibly controlled, realizes that train can turn back at an arbitrary position, by dividing
Phase region.

Second switch is opened, the control action of first switch is disconnected.The commutation control point includes positive commutation control point and commutation of turning back
Control point；
In the present embodiment, when train position information be it is positive by preset forward direction commutation control point when, jump and be positive
It to commutation state machine, executes and disconnects first switch, then the control action of second switch is connected；When train position information is reversed logical
Cross it is preset turn back commutation control point when, jump as catadioptric commutation state machine, execute and disconnect second switch, first switch is connected
Control action.
In the present embodiment, when train runs and turns back from right to left, control logic is as shown in figure 3, its control principle
The principle for running and turning back from left to right with train is identical.
In the present embodiment, by the control logic of state machine program, train may be implemented in split-phase region any position
When being turned back, according to the location information and traffic direction of train, corresponding state machine is jumped to, is realized corresponding excessively phased
System strategy, flexible performance are good.Also, state machine is only just jumped when meeting set condition, is unsatisfactory for jumping item
Part then waits under the state machine, so that control stability is good, it is ensured that and train safely passes through phase-separating section with determining direction,
Alternatively, train phase-separating section it is one or many turn back pass through phase-separating section.
It is a kind of to cross individual-phase control device, including processor and memory, individual-phase control journey was stored in the memory
Sequence, the individual-phase control program of crossing are performed achievable as above described in any item method for controlling passing neutral section, the processor
Individual-phase control program is crossed for executing in the memory.
A kind of passing neutral section control system, including position detecting device and individual-phase control device excessively as described above, institute's rheme
