Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic route control device used in a train operation management system, and to display means for displaying a train operation status on a track diagram of the automatic route control device.

[0002]

2. Description of the Related Art The display means in an automatic route control device of the prior art includes a fall of a track circuit (a device for grasping a train location in a predetermined section of a track) (during a train presence) or a lifting (train). Equipment such as the absence (located), the orientation (normal direction) or inversion (different direction) of the switch (turnout device installed at the location where the track branches), and the present status of the traffic light (lighting of the traffic light) By displaying the state information of the train, the display of the train number assigned to the train, the trouble state of the train, the train state information such as the delay time of the train, and the system state information such as the automatic control state on the track diagram, the automatic course control state is displayed. This is what the operator can grasp.

[0003]

However, in the above-mentioned prior art, the operator can clearly recognize the train operation status and the equipment status, but the operator changes the contents of the diagram due to factors such as train disturbance. In the meantime, there is a contradiction in the relation between the arrival time of the train and the departure time of other trains, and as a result, it is difficult for the operator to grasp the prediction of the order in which the automatic route control device performs the automatic route control. State. In particular, in the suburban line sections, not only ordinary ordinary trains, but also various types of trains such as round-trip trains and limited express trains coexist and travel on complex track diagrams, so the train priority provided by the automatic route control device is Due to the “priority determination” based on the determination time, the automatic route control device performs the automatic route control in an order not intended by the operator, and as a result, there is a possibility that a convergence delay of the train delay or an increase in the delay may be caused. In other words, an advance notice display of an operation system such as a diagram is performed, but not yet performed for a control system (controlled equipment) such as a track diagram.

Accordingly, an object of the present invention is to provide an automatic route control device capable of checking in advance the control order of the automatic route control for the controlled equipment.

[0005]

A feature of the automatic route control device according to the present invention that achieves the above-mentioned object is that the automatic route control device used in the train operation management system uses a train based on a train schedule, a train location, and the like. Order prioritizing display means for displaying advance notice of control priority information relating to the controlled equipment that locks the course of the vehicle. The control priority information includes track circuit information, signal information, and train information. The ranking of the automatic course control is visually displayed on the status display track screen by the ranking notice display means according to the present invention.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram showing an automatic route control device according to an embodiment of the present invention. FIG.
In the embodiment, the automatic route control device of the present embodiment includes a central control device 30 and a display device 40. However,
As shown in FIG. 1, the central control device 30 and the display device 40 may be separated and independent from each other, and the central control device 30 may be the automatic route control device 30 independently. The automatic route control device inputs facility information 1 such as a fall / lift of a track circuit, a turning direction of a switch, and a present state of a traffic signal from a field facility. The equipment information 1 is collected into display information 2, and the equipment status display processing 5 performs image processing based on the display information 2, and the image processing information 22 is displayed on the status display line screen as the equipment status by the display device 40. .

Further, the train tracking processing 6 tracks the movement of the train from the track circuit information 3 in the display information 2, thereby associating the train with the train number 24 from the diamond 20, and the train number and the train The operation information 7 such as operation information on a timetable concerned (information such as when and where to arrive, and then when and where to depart) is stored in the on-rail train table 8. Then, from the position information 12 determined by the train tracking processing 6 and the on-rail train table 8, the on-rail status display processing 13 displays image processing information 22 on the on-rail status based on the train number on the status display track screen. .

Next, using the timetable information 19 and the on-rail train table information 25, the priority determination processing 18 writes the priority information 17 for the train controlling the traffic light in the priority determination table 21.
The control output processing 10 determines a traffic signal to be controlled by extracting the train position and operation information 9 from the on-rail train table 8,
Further, the priority determination table information 16 of the priority determination table 21
From the above, it is determined whether the train to be controlled is ranked first or not. If the train is ranked first, for example, a setting signal 11 is sent to a traffic signal as an on-site facility to set the traffic signal. Make the request you want.

[0009] Then, the notice display processing 14 refers to the priority information 15 for each signal or train from the priority determination table 21, further extracts the scheduled control time 26 of the train from the on-rail train table 8, and A fixed time before the time, the image processing information 22 regarding the traffic signal or the train whose priority is determined and scheduled to be controlled, that is, the control priority information regarding the controlled equipment is displayed in advance.

[0010] Further, the ranking notice display will be described in detail. FIG. 2 is a schematic configuration diagram showing a ranking notice display means according to one embodiment of the present invention. In FIG. 2, the rank notice display means of the present embodiment includes a notice display process 14 and a priority determination table.
21. Generally, an automatic route control device
In order to determine the order in which trains are controlled, various priority decisions are made. The automatic route control device according to the present embodiment also makes four priority determinations and creates a priority determination table from the results. Furthermore, depending on the delay situation of the train, the priority judgment table is rewritten,
Priority judgment change processing for automatically changing the priority order is also performed.

Next, five tables constituting the priority judgment table according to one embodiment of the present invention will be described in detail. Station Entry Order Table The station entry order table 21a shown in FIG. 2 defines the order in which the trains to be controlled use the exits from the present station to other stations. The station entry order table 21a is created by the priority determination process 18 by referring to the departure time registered in the diagram 20 and the exit used by the train from the diagram information 19.

Station Entry Order Table The station entry order table 21b shown in FIG. 2 defines the order of trains entering from other stations with respect to the station to be controlled. The station entry order table 21b is created for each entrance by the priority determination processing 18 by referring to the arrival time registered in the schedule 20 and the entrance of the train from the schedule information 19.

Line Arrival Order Table A line arrival order table that defines the order in which trains use (arriving) the lines for all the lines (platforms at which the train stops) existing at the station to be controlled. 21c
It is. The track arrival order table 21c is created by the priority determination processing 18 by rearranging the trains that arrive at a certain track among the trains entering from a plurality of entrances in the order of arrival time. That is, it is created by referring to the station entry order file.

Pointer use order table For all points present at the station to be controlled, the order in which the train uses the traffic light including the point is specified by the point. It is a container use order table 21d. First, the priority determination process 18 is performed for the arriving train.
The traffic signals to be used are determined in order from the upper trains registered in the station entry sequence table 21b, and the switch use sequence table 21d is created based on the arrival time of the switches used by the traffic signals. . Next, for the departure train, the traffic signal to be used is determined in order from the higher-level train registered in the station entry order table 21a, and based on the departure time for the switch used by the traffic signal. Is registered in the switch use order table 21d.

Order Change Schedule Tables The four order tables described above are:
In the case where the higher-ranked trains in each order table are late, the trains in the order of registration or lower have the first priority.
Therefore, it is impossible to control the traffic light. In such a case, the delay status and the on-rail status of the train are acquired from the on-rail train table 8, and if a higher-ranking train is delayed, a predetermined time before the required time predetermined for priority determination is obtained. It is possible to temporarily store the four pieces of information scheduled to be changed in each of the four order tables in the order change scheduled table 21e, and to change each order table at the timing when the required time has passed and the scheduled change time has passed, by automatic route. This is executed by a priority judgment change processing means (not shown) provided in the control device. For this purpose, the order change schedule table 21e is prepared.

By the way, in the automatic route control device, in the control output process 10, based on the train number assigned by the train tracking process 6, the train location, and the above-mentioned priority judgment,
Control the traffic light that can go to the arrival line of the train specified in. The priority determination at this time is based on the determination as to whether or not the following three conditions are satisfied with respect to the train to be controlled (train to be controlled).

(I) The use order of the switches used by the traffic signals to be controlled is that the own train is the first. (ii) If the train is an arriving train, the own train is the first in the line arrival sequence of the line about to arrive. (iii) If the train is a departure train, the own train is ranked first in the station entry order of the exit that is about to enter. Then, the control priority information is displayed in advance using the priority determination table.

That is, the feature of the automatic route control device according to the present invention is that, based on the result of the priority judgment held in the automatic route control device, the train having no cause of hindrance to other trains is assigned the highest priority train. Then, priorities are sequentially assigned so that trains higher than oneself are not obstructed, and then the following three displays are performed based on the priorities. (1) For each train, the automatic route control device displays a signal to be controlled, a track circuit to be locked by the signal, and a switch in a color-coded manner in the controlled order. Further, when the priority order is changed in the priority determination, "change will be" is displayed in advance from a certain time before the change until the change. Furthermore, when multiple trains occupy one traffic light for different reasons in the priority judgment,
Show deadlock. (2) For a traffic signal that is not disturbed by other trains according to the priority determination, a warning display indicating that the traffic signal can be controlled is displayed because the traffic signal is controllable. (3) The train numbers tracked by the automatic route control device are displayed in different colors for each priority order to be controlled.

Further, when the above state is displayed,
Due to the delay of the train, etc., due to the factors such as the delay of the train, if the order of the obstacles is changed due to the priority judgment made in the automatic route control device, When the priority determined above is reversed, the display shown in (1) to (3) above is displayed as a blink display, and the display of the priority of the target train to be changed is also displayed as a blink display. This indicates that there is a possibility that the priority of the train may be changed after the fixed time has elapsed.

Hereinafter, the individual features will be described in detail. (1): Track circuit notice display Track circuit notice display for displaying track circuit information is realized by track circuit notice display processing 14a shown in FIG. And
As a track circuit notice display executed by the rank notice display means,
There are three types as follows. First, the on-rail train table 8 is extracted with reference to the on-rail train table 8 to control the traffic signals of all trains that are or are going to be at the station to be processed. Next, with reference to the priority determination table 21, the information for the track circuit is obtained.
By referring to the control priority order of the scheduled control signals as 15a, it is determined whether or not control of each control scheduled signal of the train is possible. According to this method, the following three (a) to (c)
Is performed.

(A): Track circuit normal notice display FIG. 3 is a diagram showing a display example of the track circuit normal notice display of the present embodiment. In FIG. 3, the display created by the equipment state display processing indicating the state of the on-site equipment includes a falling state of the track circuit (lower 2T) indicated by 111, a lifting state of the track circuit (2LT) indicated by 109, and 108 Track circuit indicated by
Turning direction of the switch (11b) included in (11bT),
There is a present state of the traffic light (3LX) indicated by 106 and the like.
(1RBT) indicated by 105 is the name of the track circuit, (3LX) is the name of the traffic signal, indicated by 107, 103
Is the home (line).

(1A) in the frame indicated by 101 is
This is the train number assigned to the train line (falling state) indicated by 111. Here, the train 1A is a traffic light (1
RB) to control to 1 RBT.
At this time, the automatic course control device controls the traffic light 1RB to secure the course from the lower 1T to the 1RBT. However, since the 1A is an arriving train to control the 1RB, it is included in the traffic light 1RB. Switch (11a),
(11b) and (21a) the order of using the switches and 1R
All the BT line arrival orders must be first.

FIG. 3 shows a display example when the above-mentioned priorities are all 1A, that is, when the control of the track circuit is normally performed. Before the predetermined time (constant time) of the scheduled control time, there is no display outside the track circuit indicated by 110 (display in the order of using the switches) and outside the track circuit corresponding to the line indicated by 104. The display (display in the order of the number of arrivals) is performed, indicating that the route can be set. Note that the track circuit normal notice display of this embodiment is
This is performed by “outside display” (or outer frame display) using a band display that protrudes outside along the corresponding track circuit.

In a track circuit having a switch, as shown in FIG. 3, there is a method in which a plurality of outer displays are displayed in succession according to the turning direction of the switch, as shown in FIG. , The actual switch (the switch 11 indicated by 151 in the figure)
No. irrespective of the turning direction (No. 151 in the figure, the localization direction, that is, the straight traveling direction), the direction turned by the traffic light 1RB (102) to be controlled
Another method of continuously displaying the outside of the track circuit 153 along the arrow 154 in the drawing is also conceivable.

On the other hand, at this time, the train 2A is about to depart from the entrance and exit of the 2LT by the traffic light 2LX, but the switches 21a and 11b included in the 2LX have priority over the train 1A. Is occupied and hindered, that is, since the control priority is low, it is assumed that the track circuit normal announcement display by the outside display is not performed.

That is, a track circuit notice display indicating that control is possible for each of the priority order and without hindering other trains is performed on the track circuit row to be locked of the traffic signal to be controlled, and which train By displaying whether the traffic light can be controlled, it is possible for the operator to recognize the train control order and the place where control is to be waited and the partner's train with higher priority than the own train before the timing of performing the control output. It is characterized by doing. Note that “normal” is normal processing as an automatic course control device, and is intended by the operator (plan).
It is a matter of whether or not it matches, and the purpose of the present invention is to confirm and confirm this.

(B): Track circuit change notice display In FIG. 3, the original train 1A arrives at 1RBT first, and then the train 2A departs for 2LT. If the result is that the train 2A is also slightly delayed, the above-mentioned priority judgment change processing means changes the use order of the points 21 and 11 and the train 2A departs first. I do. At this time, in the priority judgment change processing, the actual
A predetermined time before the change of the use order of the point 1 is changed, the scheduled change time and the contents of the change order of the switch are written in the order change schedule table 21e.

Therefore, the track change notice table 21e is referred to by the track circuit change notice display which is one of the track circuit notice display processing 14a (notice display processing 14), and the switches 21a and 11b are referred to. It is detected that the order of use is changed and the 1RB that the train 1A is trying to control cannot be controlled. As a result, AT, 11aT, 11bT,
For 21aT, the track circuit normal announcement display (outside display) shown in FIG. 3 is blinked, and after a predetermined time has elapsed, 1RB is not automatically controlled, that is, information that the control priority is changed. Notify. For example, flashing and giving an advance notice that this track circuit normal notice display is "changed after a certain time" by the priority determination change process is referred to as a track circuit change notice display.

That is, when the priority determination processing for determining the priority of a train automatically changes the priority of a train due to the establishment of a predetermined time relationship, a certain time before the priority is changed By displaying the track circuit normal advance notice display described in (a) above in a blinking manner, it is possible to control the train by displaying the advance notice that the priority judgment processing is about to automatically change the priority before the change. It is characterized in that the operator can know in advance that the order is changed.

(C): Track Circuit Abnormality Notice Display FIG. 5 is a diagram showing a display example of the track circuit abnormality notice display of the present embodiment. In FIG. 5, the train 1A (202) is a traffic light 1
The RB (205) is controlled and is about to arrive at the track circuit 1RBT. The train 3A (201) is trying to reach the track circuit 1RAT by controlling the traffic light 1RA, but the actual time relationship is inconsistent in the section of traffic control, and in fact, 1A (fall state 304) enters first. Even though
In the case of 3A (falling state 203) that has entered later, the order of using the switches of the switch 11a (206) has priority.

Here, since the train 1A is located in front of the train, the train 3A cannot be at the control timing.
A is in a so-called deadlock state in which it cannot control 1 RB. Here, the order of use of the points 11a becomes a problem, and both the trains 1A and 3A are waiting for control.
(Preliminary notice display processing 14) sets the outside display of the point 11a as a warning display (207). This is the track circuit abnormality notice display.

That is, in a case where a plurality of trains occupy different positions in the order of controlling the course of each other at different places, and as a result, both trains are in a deadlock state where control output cannot be performed, When it is not possible to determine whether or not the priority is high, control output conditions are displayed by displaying a deadlock color on the track circuit row that locks the traffic lights at places where each train can control and output. Is in a deadlock inside and the control output cannot be performed even when the control output timing is reached, so that the control output is impossible where the train is delayed due to train control waiting (how far can be controlled) Can be recognized by the operator before the timing of performing the control output.

(2): Signal Notice Display The signal notice display for displaying the signal information is realized by the signal notice display processing 14b shown in FIG. Then, the signal notice display executed by the rank notice display means can be controlled without hindering other trains by using the signal information 15b from the priority judgment table 21 created in the priority judgment. As shown in FIG. 3 at 102, a distinction display is performed on the outside of the traffic light symbol and on the background of the traffic light name. The distinction display may be “outside display” using a band display that extends outside. A partial display as illustrated in 155 of FIG. 4 may be used.

In the case where another train is obstructing, as shown at 205 in FIG. 5, the signal notice display ("outside display" as a distinction display) is not performed. As a result, the operator can easily grasp the control order of the train or the trouble state. That is, for traffic lights that are not hindered by other trains,
It is characterized in that an operator can grasp in advance the control order and the trouble state of the train by displaying the traffic signal that the train is scheduled to output for control in advance.

(3): Train number priority display Train number priority display for displaying train information is realized by the train number priority display processing 14c shown in FIG. 2 processing the train information 15c from the priority determination table 21. Is done. And, the train number priority display executed by the rank notice display means,
Trains that do not interfere with other trains in priority determination are identified as the highest-priority trains by the highest-level color (for example, red as level 1), and train number priority display is performed.

As a specific display, as shown in FIG. 3 at 112, an outside display is performed on the background of the train number frame, and then other trains which are affected only by the own train at level 1 are displayed at level 2 (for example, (Yellow as level 2), sequentially assigning levels, sorting by color corresponding to that level, and displaying train number priority.

However, when a plurality of trains compete with each other, the train number priority display is not performed as illustrated in 201 and 202 in FIG. In this embodiment, the order of the control priority order is represented by color. However, the order of the control priority order may be affixed to the order number, or may be arranged in order from the top. This makes it easy for the operator to visually grasp the control sequence of the train and the trouble situation. In other words, the train numbers are displayed in different colors in order of priority, and the relation between the priorities of the trains is displayed in a state (train number priority display), so that the operator can grasp the train control order and the trouble situation in advance. It is characterized by the following.

As described above, in this embodiment, the automatic route control device has a time relationship for making various priority judgments, a train position, and a station entry sequence and a line arrival sequence created from the schedule.・ Advance notice display based on track departure order and switch point use order is superimposed and displayed on the status display track screen, so that the automatic route control order is displayed in advance and the order in which the automatic route control device automatically controls An operator can recognize the information in advance.

In other words, in order to notify the operator of the priority determination as the control priority of the controlled equipment to be controlled from now on, there is a diagram that specifies the arrival and departure time of each train station and the number of the train to be departed. And reserves the route through which the train passes based on the timetable and the train location (locked)
In the automatic route control device or the train operation management system that automatically controls the traffic signal to be controlled, the priority order information of the automatic control performed on the controlled equipment is displayed in advance.
In this way, if control is performed in an order not intended by the operator, it can be corrected by manual intervention, and the occurrence of train delay or the like can be prevented.

On the other hand, when a notice is displayed on the display device 40 (or when the notice is displayed), each of the above-mentioned displays is switched to various display modes.
Track circuit normal warning display, Track circuit abnormality warning display, Track circuit change warning display, Traffic signal warning display, Train number priority display, No warning display
Switching display is performed as in (status display only).
Thereby, the operability (handleability) of the operator is improved.
