Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a train schedule compatible device in a train operation management system.

In a train operation control system for railways, signals are automatically controlled by a computer installed in a central control room, and based on this, each train driver operates each train to control operation. . For this reason, the train operation number (commonly known as "row number")
It has a train operation order storage device that encodes and stores a train schedule consisting of reference station departure times, etc., and also associates this train schedule with each train (having a train number in advance) that leaves the depot. Based on the actual train position information sent from a large number of axle detectors installed in parallel on the tracks, the information includes the ○A train number, ○B train position, ○C train's running direction, etc. It is equipped with a train position information register that encodes and registers train position information. Based on this train position information, the traffic control computer commands the signal control described above, and places the train at the corresponding position on the route on the central traffic display board.
Display the column number on the dynamic screen.

As a result, train operation management progresses, and as long as train operation is within normal range, the dispatcher is usually not required to take any particular action.

If, for some reason, a significant unrecoverable train delay occurs or the train operation management system becomes temporarily inoperable, the dispatcher will be able to change or thin out the timetable, turn back trains midway, or replace broken vehicles. The system manually issues traffic light control commands by selecting an appropriate action from among 30 to 40 types of actions, such as vehicle replacement, temporary parking, and exit, or a combination of multiple actions.

In train operation management, when accidents or other factors often cause the train schedule to not correspond with the trains operating on the tracks, conventionally the dispatcher would assign one train to each train on each track based on the operation chart. I am taking a method. This method has the disadvantage that when there are a large number of trains, it takes a lot of time to complete the work to match the timetables for all trains.
The reason for this is that it has no choice but to rely on human labor.

An object of the present invention is to relate to a train schedule management device that can quickly shift trains that are controlled by a method other than timetable management to timetable management by a train operation management system.

The present invention is provided on the operation panel of the central control room,
an operating means for instructing a train schedule corresponding process; and means for sequentially comparing and collating each train position information in the train position information register with each timetable information in the operation order storage means in response to the operation of the operating means; In response to one of the results of the sequential comparison and verification exceeding a scheduled tolerance, means for shifting the train schedule by one train to a subsequent timetable and sequentially comparing and verifying the position information of each train; A means for displaying each train position information and each train schedule in a form that corresponds to each other in response to completion of comparing the position information with each train schedule within an allowable error range; an operating means for approving the train schedule corresponding action, and in response to the operation of the approval operating means, each train timetable is made to correspond to each of the train position information and stored as new train position information in the train position information register. The invention is characterized in that it is provided with means.

With this configuration, for example, when the train operation management system becomes inoperable, each train position information in the train position information register will not be associated with the train schedule in the operation order storage means.
However, the location of trains in operation is updated moment by moment as the train progresses. Then, the train position information is compared with the position information of a certain train obtained by converting it from the train diagram, and if it is outside the allowable error range, it is compared with the position information of the next train on the train diagram. If the comparison results are within the allowable error range, it means that each train position information in the train position information register for a certain train corresponds to the train schedule. Therefore, after confirming that the measures can be taken for all trains, and once the measures have been taken, the information on the train schedule stored in the operation order storage means is stored in the train position information register, and from now on, the train operation will be continued. It is now possible to shift management from manual to train operation management systems, and the train operation management system can restore normal operation management. The operations of the dispatcher during this time are limited to instructing the start of the train schedule response process and approving the displayed response measures, which greatly reduces work and labor.

FIG. 1 is a block diagram showing an embodiment of the present invention.

The train schedule compatible devices include an operation panel 1, a train position information register 2, a train operation order storage device 3, a comparison and verification circuit 4, a process display device 5, a register 6, a train information setting device 7, a counter 8, and a travel time register 9. It consists of The operation panel 1 is used for inputting response commands and approvals from the operation management system. The train position information register 2 stores the position information of trains in operation sent from multiple axle detectors placed side by side on the tracks, coded together with train numbers, train running directions, etc. has been done. In addition, the operation number of the train departing from the reference station based on the train schedule,
A train operation order storage device 3 that stores departure times encoded in the order of operation is connected in parallel via a comparison and verification circuit 4 for comparing and verifying information. The comparison and verification results (corresponding combination results) in the comparison and verification circuit 4 are displayed on the process display device 5. The corresponding combination results are stored in the register 6, and after approval is input from the central management side based on this stored information, the information in the train operation order storage device 3 is set in the train position information register 2 via the train information setting device 7. Note that the counter 8 counts the number of trains on the track at the time when a response command is issued from the operation panel 1.

When a corresponding command operation is performed from operation panel 1,
From the train position information register 2, among all the trains on the track at the time the response command was issued,
The position information of the leading train farthest from the reference point is transferred to the comparison and verification circuit 4, and among the timetables of trains in the operation order storage device 3 that can be on the track at the time when the above-mentioned corresponding command is issued, A comparison is made between the train furthest from the reference point and the travel time required from the reference point to the local point, and if it is within the tolerance (can be set arbitrarily), the train schedule is stored in the operation order storage device. The address within 3 and
The storage address of the leading train in the train position information register 2 is stored in the correspondence storage register 6 as a reference combination. Next, the number of trains in the train position information register 2 is stored in the counter 8, and the number of trains in the train position information register 2 is stored in the train position information register 2 based on the address of the reference combination stored in the corresponding storage register 6.
Comparison and verification in the operation order storage device 3 are performed for all trains currently on the track, starting from the train farther from the reference point to the train closer to the reference point.
This is repeated for the number of trains stored in the counter 8, and if it is within the tolerance, it is stored in the corresponding storage register 6. If a combination other than the allowable error occurs in the comparison and verification performed after the standard combination, the train information storage register 2 stored in the correspondence storage register 6 and the operation order storage device 3
Among the standard combination information storage addresses in , the storage address in the operation order storage device 3 is corrected to the next information address,
That is, each timetable information in the operation order storage device 3 that is compared with the position information of each train on the track is compared based on a new reference combination as the timetable for one train after the previously compared and verified timetable. Correspondence can be achieved by performing verification. When the correspondence is completed as described above and all the compared and verified train combinations are within the allowable error, the results of the correspondence are displayed on the process display device 5 as described later. When approval is input from the operation panel 1, the train information setting device 7 reads the combination storage address information from the corresponding combination storage register 6,
The information in the operation order storage device 3 is stored in the train position information register 2.

FIG. 2 is an explanatory diagram showing a specific example of correspondence comparison and verification. In FIG. 2, the current train b and the timetable train J are the reference combination at the current time T ₀ (the current train is in the lead and the corresponding time difference T ₂ ). Here, if we consider the case where the next train a and the next scheduled train A are compared, the corresponding time difference T ₁ between the train a and the next scheduled train A (scheduled train is in advance) is outside the arbitrarily specified tolerance. In this case, by changing the standard combination of timetable train J to the next timetable train A (current train precedes, corresponding time difference T ₃ ), in other words, by setting current train b as timetable train A, the next current train a becomes timetable train B. (Present train,
It is possible to correspond to the corresponding time difference T ₄ ).

The processing of the present invention is preferably executed by program processing by a central operation management computer. That is, in FIG. 1, for the sake of clarity, they are shown as functional blocks, but in practical terms, the comparison and verification circuit 4, train information setting device 7, etc.
It can be executed by computer program processing.

Therefore, in the following, the flow will be explained assuming that the train schedule corresponding processing is executed as the program processing of the central operation management computer.

FIG. 3 is a flowchart showing the processing procedure from inputting a command to allocating a timetable for that time period to trains actually on the line and outputting the results on a process display.

The process is started by the commander pressing down on the corresponding button switch on the operation panel. In FIG. 3, in steps 10 and 11, trains on the line and trains that can be on the train on the timetable are set as shown in FIG. This means the current train according to the position information of each train in the position information register 2, and the trains shown in white indicate the trains operating on the timetable).As shown in FIG. Set number 100 and timetable operation number 200. In step 12, the number of trains counted in block 10 is set in a counter for correspondence comparison. step
In step 13, the required time T _A from the reference point to the local point is calculated based on the train information indicated by the on-line train address in the train position information register 2 according to the flowchart in FIG. In step 14, based on the information shown in the train schedule address in the register 6, the train position on the timetable is calculated by the time T _B required from the reference point to the current point. In step 15, the required time from the reference point calculated in steps 13 and 14 is compared and it is determined whether it is within the allowable error (arbitrarily specified as early onset α and late β). A comparison of the required times in step 15 is performed by the comparison and verification circuit 4 shown in FIG.
If it is within the tolerance, train position information register 2
This means that the train information is associated with the train schedule.

In step 16, information on compatible combinations is sequentially stored in the register 6. In step 17, it is determined from the train counter whether all trains have been handled. In step 18, the counter for processing for the next train and the information to be processed are updated to the following.
In step 19, when the corresponding combination is outside the allowable error, the combinations up to the current point stored in the register 6 are deleted, and the leading reference combination is shifted by one train to change the combination. In step 20, the corresponding combination information in the register 6 is displayed on the process display 5 of FIG.

Here, the process of step 13 in FIG. 6 mentioned above will be explained in detail. Step 131 stores the running time from the reference station stored in the operation order storage device to the current position of the train in the train position information register 2, and the running time between each station including the stopping time. Calculate from the running time register 9. In step 132, based on the location classification information in the train location information register 2, it is determined whether the train is on the platform or is running. In step 133, when the train is running between stations, the calculated required time is corrected by subtracting the corrected time (interstation running time/2).

FIG. 7 is a flowchart showing in detail the process of step 19 in FIG. In step 191, the corresponding combinations stored in register 6 up to the current point are deleted. In step 192, the address of the train schedule information among the reference combinations stored in the register 6 is updated to the address of the next train information.
FIG. 8 shows the address update state between each device in this case.

FIG. 9 is a flowchart showing the processing procedure from approval input to diamond planting processing.
The process is started by the commander pressing down on the corresponding pushbutton switch on the operation panel 1. In step 20, the number of combination information in the register 6 is set in a counter. In step 21, combination information is read from register 6. In step 22, step 21
The information (diagram) in the train position register 2 is set in the train position register 2 based on the information address in the train position register 2 and the information address in the train position register 2 in the information taken in. In step 23, it is determined whether all combinations have been completed. In step 24, counters and addresses for processing the next combination are updated. FIG. 10 shows an example of a diagram finally displayed on the process display device in this manner.

In this way, in one embodiment of the present invention, when the train schedule and the running train no longer correspond, all that is required is a button operation to command the train schedule handling process, and the assignment to the train schedule ( All available train vs. timetables are found and displayed on the display. Next, if you decide whether the displayed train schedule is acceptable or not and press the approval button, the train schedule response process will be automatically executed, and from then on, operation management such as signal control will be carried out accordingly. . Therefore, the response processing time is significantly shortened, and the burden on the dispatcher is reduced accordingly.

As is clear from the above, according to the present invention, trains placed outside of timetable control management can be quickly transferred to timetable control management.
