Description
Technical field
The present invention relates to a kind of automatic monitored control systems of urban track traffic, face more particularly, to a kind of automatic monitored control system
When speed limit intelligent route selection method.
Background technique
During urban track traffic operation, automatic monitored control system need to issue setting or cancel temporary speed limitation order to ground
Face automatic train protection system.Ordering the mode issued is usually that line facility is manually selected on yards design by operator, will
These line facilities are disposably issued to railway trains automatic protective system.Its defect is as follows:
1. user's operation low efficiency.When multiple line facilities need to issue temporary speed limitation order, it may be necessary to which user holds
Row is multiple.Availability is very poor in the case where entire station large area speed limit.
2. temporary speed limitation function needs secondary-confirmation, user is easy to cause by way of manually selecting line facility list
Confirmation selection twice is different, and causes to operate unsuccessful
3. work as Existence restraint condition requirement, for example the positioning branch and antiposition branch of some track switch cannot be issued simultaneously.
It needs to exclude by the operation of user.
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of automatic monitored control systems
Temporary speed limitation intelligent route selection method.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of automatic monitored control system temporary speed limitation intelligent route selection method, in automatic monitored control system temporary speed limitation operation interface
Starting point line facility and terminal line facility are selected, by an intelligent optimal path lookup algorithm, calculates intermediate institute automatically
The line facility of process；Railway trains automatic protective system is issued to after being confirmed by user again.
The intelligent optimal path lookup algorithm specifically:
Step S0, a route is formed according to the connection relationship of signal line equipment according to wayside signaling devices plan view
Topological structure；
Step S1, the starting point line facility of user setting is transformed into the wire topologies, as initial plant, will used
The terminal line facility of family setting is transformed into the wire topologies, as termination device, enters step S2；
Step S2, start node is added to traversal of lists tail portion, enters step S3；
Step S3, judge to traversal of lists whether be it is empty, if it is empty, then it is assumed that there is no initial plant to termination device it
Between path, return search failure, it is desirable that user reselects equipment；If not empty, then the line facility at the top of list is taken out,
Enter step S4；
Step S4, judge whether the line facility is termination device, if so, entering step S7；If it is not, then by the line
Traversal of lists is added in pipeline equipment, enters step S5；
Step S5, the connection relationship according to the line facility on the topology finds out all routes for having connection therewith
List of devices enters step S6；
Step S6 traverses the line facility list, if some line facility not in traversal of lists, put it into
Traversal of lists tail portion, return step S3；
Step S7, it is recorded by the lookup of the termination device, calculates the intermediate equipment path currently passed through, enter step
S8；
Step S8, all paths found, if the list of devices on certain paths be unsatisfactory for it is predefined about
Beam condition then excludes the paths, enters step S9；
Step S9, optimal path is found out, algorithm terminates.
For section without a switch, left connection equipment and right connection equipment are calculated.
For switch section, the preceding connection equipment of trouble, the equipment that is located by connecting are calculated with antiposition and connects equipment.
The step S9 specifically: if finding optimal path there is only one, feed back to user's confirmation, algorithm knot
Beam；Mulitpath if it exists selects shortest path then according to the kilometer post weight of line facility, feeds back to user's confirmation, algorithm
Terminate.
Compared with prior art, the invention has the following advantages that
1, the present invention passes through an intelligent optimal path lookup algorithm, only needs user to select initial plant and end in operation
User's operation efficiency is greatly improved in only equipment.
2, the present invention can be found out by an intelligent optimal path lookup algorithm and be confirmed for the first time in secondary-confirmation
Identical path can reduce the maloperation of user.
3, the present invention is judged by the way that restrictive judgement and kilometer post weight are added in the selection of mulitpath, automatic to calculate
The initial plant and the optimal path among termination device of user setting out, improves the intelligence of operation, reduces user's operation
Complexity.
Detailed description of the invention
Fig. 1 is the intelligent optimal path lookup algorithm flow chart of the present invention；
Fig. 2 is the line topological figure of embodiment.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiment is a part of the embodiments of the present invention, rather than whole embodiments.Based on this hair
Embodiment in bright, those of ordinary skill in the art's every other reality obtained without making creative work
Example is applied, all should belong to the scope of protection of the invention.
Such as Fig. 1 and Fig. 2, the specific process flow of intelligent optimal path lookup algorithm is illustrated:
Step S1, the starting point line facility for assuming user setting is T1.It is assumed that the termination device of user setting is T2.Into
Step S2
Step S2, start node T1 is added to traversal of lists tail portion (T1), enters step S3
Step S3, judge whether to traversal of lists (T1) be empty.Due to being not sky, then the line facility at the top of list is taken out
T1 becomes empty to traversal of lists at this time.Enter step S4
Step S4, T1 is not termination device, which is added traversal of lists (T1).Enter step S5
Step S5, the connection relationship according to T1 on the topology finds out all line facility lists for having connection therewith,
Only P1.Enter step S6
Step S6 traverses the line facility list (P1) and then puts it into since P1 is not in traversal of lists wait traverse
List tail (P1), enters step S7
Step S7, judge whether to traversal of lists (P1) be empty.Due to being not sky, then the line facility at the top of list is taken out
P1 becomes empty to traversal of lists at this time.Enter step S8
Step S8, P1 is not termination device, which is added traversal of lists (T1, P1).Enter step S9
Step S9, the connection relationship according to P1 on the topology finds out all line facility lists for having connection therewith,
For T1, T2, P3.Enter step S10
Step S10 traverses the line facility list (T1, T2, P3), since T2 and P3 is not in traversal of lists, then will
It is put into traversal of lists tail portion (T2, P3).Enter step S11
Step S11, the iterative process of circulation step S3 to step S6 is until taking out termination device T4 to traversal of lists.This
When traversal of lists be (T1, P1, T2, P3, T3, P4, P2).Enter step S12
Step S12, it is recorded by the lookup of T4, calculates the intermediate equipment path currently passed through.Then there are two paths
T1-P1-T2-T3-P2-T4 and T1-P1-P3-P4-P2-T4.Enter step S13
Step S13 checks that this two paths excludes Yi Tiaolu according to predefined constraint condition and kilometer post weight
Diameter.Remaining optimal path is fed back into user's confirmation, algorithm terminates.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can readily occur in various equivalent modifications or replace
It changes, these modifications or substitutions should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with right
It is required that protection scope subject to.
