Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to C which is transmitted from a track circuit device which is a ground facility via a train centralized control device.
The present invention relates to a train operation management system that tracks and controls trains based on TC information.

[0002]

2. Description of the Related Art Conventionally, in a system that manages train operation based on CTC information transmitted from a train centralized control device, CTCs such as drop / lift information of a track circuit from the train centralized control device are used as train presence information. Information received and its CT
Tracking and control of trains are performed based on C information. By the way, in the conventional train operation management system, once a train disorder, such as a train delay, is disturbed in a train operating at high speed and high density, it is very difficult to recover the disorder of the train schedule. . There are various causes for the disorder of the diamond, but one of them is irrational CTC.
There is provisional tracking of trains by information. When the computer that tracks and controls trains acquires irrational CTC information, it replaces the tracked train with the temporary train number, specifically the train number of the tracked train, and performs the tracking process. continue. However, since the route control based on the schedule cannot be performed with the train number of the provisionally tracked train, it is inevitable that train delay will occur unless the train number of the provisionally tracked train is fixed. Therefore, the ordering person confirms the in-rail position and the train number of the train by using a railway telephone or the like, corrects the temporary tracking number to the train number of the train actually traveling, and confirms it. Alternatively, if the ground equipment has a train number detecting device, the ordering person confirms the train after waiting for the temporarily tracked train to pass through the train number detecting device. The reason why the train centralized control device transmits this irrational CTC information is
Abnormality of the continuous track circuit due to power failure due to failure of the power supply system of the power supply to the track circuit which is the ground equipment (including natural disaster such as lightning strike) or failure of the track circuit device itself (including rail damage) Transient CTCs such as the status, the acquisition timing deviation when the train centralized control device acquires track circuit information from the track circuit device, the transmission timing and the transmission error when transmitting the CTC information to the train tracking / control computer Generated by information. Further, even when the continuous CTC information is normally restored, the in-rail position of the train before and after the CTC information is not in the abnormal state does not always match, and even when the CTC information is normally restored,
It is unavoidable to fall into the tentative tracking state by rationality judgment of CTC information in train tracking.

[0003]

As described above, in the conventional train tracking / control by the train operation management system, irrational CTC information is transmitted from the train centralized control device to the train tracking / control computer. At this time, the tracking of the train falls into a temporary tracking state, and therefore, when the train is fixed, after the failure recovery of the ground equipment, or when the temporary illegal information of the CTC information is generated, including the intervention of the ordering staff There is a problem that the train cannot be confirmed unless the above time is required.

An object of the present invention is to provide a train tracking process in a train operation management system with toughness that does not cause a train to enter a temporary tracking state due to irrational CTC information, and to recover ground equipment from a failure state. At that time, it is to promptly and automatically determine the position of the train and the corresponding train.

[0005]

In order to solve the above-mentioned problems, a function of storing a track circuit (reference track circuit) in which the tail end of a train to be tracked is located, and a track link of a track circuit in which a train to be tracked progresses And the function of storing the on-rail link and the function of determining an abnormal drop or abnormal lift of the track circuit from the reference track circuit and the train length of the train, and the reference track circuit of the train to be traced has been lifted. In this case, when the track circuits are checked in order according to the track links and the track circuits that are in a falling state are detected, the track position of the train and the track trains are specified as tracking trains, and a track circuit that has abnormally dropped or is lifted is detected. , Recognize the track circuit as an illegal track circuit. In addition, if a failure occurs in the ground equipment and all track circuits are in a dropped state, when the ground equipment is recovered, the track circuits are sequentially checked from the reference track circuit before the ground equipment failure according to the on-rail links, and the train When the track circuit in which the tail end is located is detected, the train is specified as the track train before the ground equipment failure.

According to the present invention, the on-rail position and the on-rail train of the train to be traced are determined as the tracking train based on the information on the reference track circuit and the on-rail link information on the track circuit. This is to judge the rationality of the CTC information transmitted through the train centralized control device, and it is possible to prevent the tracking state of the train being tracked from falling into a provisional tracking state. It is possible to control the route according to the schedule for the train, and as a result, it is possible to prevent the occurrence of delay and delay spread of the train. In addition, even when recovering from a breakdown of ground equipment, after the failure of the reference track circuit that had dropped just before the occurrence of the failure, the train runs idle (a train running at high speed stops Even if the reference track circuit concerned goes up due to the fact that the distance is required.), That is, the train passes by, the track circuits are automatically checked from the reference track circuit before the failure occurred in accordance with the on-rail links, and the train falls. Tracking trains that existed before the failure occurred can be quickly and surely detected by identifying the track circuit that is running, and the trains can be identified. Control can continue to be executed.

DETAILED DESCRIPTION OF THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a train operation management system according to an embodiment of the present invention. The train operation management system stores a train tracking / control computer 2, a diamond file 3 that stores timetable information of a planned timetable creation device, an on-track track circuit information file 4, a route name, a signal signal state, a route opening direction, etc. From the traffic signal information file 5, the track link information file 6 that stores the track direction from the traffic signal information, the on-track link track circuit file 7 that stores the track circuit that is the target of the track circuit inspection of the train, and the command console (operation control terminal) 8 Become. Further, as a ground facility (on-site), when a train running on the rail travels on a rail, CTC information, that is, a traffic signal issued from a track circuit device (not shown) or a train number detection device (not shown) which is a ground facility. information,
The train centralized control device 1 is installed for recognizing track circuit drop / lift information and train number information, and for controlling traffic signals based on traffic signal control information transmitted from the train tracking / control computer 2. The train tracking / control computer 2 updates and stores the on-track track circuit information file 4 and the traffic signal information file 5 based on the CTC information transmitted from the train centralized control device 1, and also determines the opening direction of the route from the traffic signal information. The route link information file 6 for recognition is updated.
Further, a track circuit to be a target of track circuit inspection of the train is created based on the track circuit information on track, signal information, and route link information, and the track link circuit file 7 is updated and stored as the track circuit track information based on the information. To do. Further, the train tracking / control computer 2 carries out a series of these processes to transmit the updated file result to the command console 8 which is a terminal for the commander to grasp and monitor the train operation status. The command console 8 has a function of displaying the transmitted information, and a function of displaying information such as an alarm and outputting a notification. As shown in FIG. 2, the on-rail track circuit information file 4 is composed of an on-rail train table 4-1 and a track circuit tracking table 4-2. The on-rail train table 4-1 is a track circuit tracking table 4 for each on-train train. -2 exists in each track circuit unit. The on-rail train table 4-1 and the track circuit tracking table 4-2 are linked by the address information of the on-rail train table pointer of the track circuit tracking table 4-2. Here, in FIG. 3 (Table 1), the configuration of the on-rail train table,
FIG. 4 (Table 2) shows the configuration of the track circuit tracking table.

Next, FIG. 5 shows a CTC which is a basis for train tracking.
Regarding the information, particularly the track circuit information, the relationship between the mechanism of the track circuit device and the CTC information is shown. FIG. 5A shows a mechanism of the track circuit device, in which the conductive rail 21 is regarded as a part of an electric circuit and the track circuit power supply 2 is provided on the rail 21.
Rail electric current is supplied from 3 and a current is sent to the train detection relay 22 through the rail 21, and the action of the train detection relay 22 is used to operate the relay switch 24 to detect the presence of a train. Here, in the train detection relay 22, when a current is supplied, a magnetic field is generated in the relay, the relay switch 24 is induced by the electromagnetic force, and the switch is turned on (hereinafter, ON state). Positioning this state as the state where the train is not in line, this is called the uplift of the track circuit. That is, this represents the CTC information on the track circuit. Further, when the train 25 enters the track circuit, both rail circuits are short-circuited by the train wheels 26 and the axles 27 of the train which are conductive. When the rail circuit is short-circuited by the axle 27, the rail current is not supplied to the train detection relay 28, the train detection relay magnetic flux disappears, and the relay switch 29 is opened (hereinafter, OFF state). This state is regarded as the state where the train is in line, and this is called a track circuit drop. That is, this represents the CTC information of the track circuit drop. Train tracking / control computer 2
Tracks the train based on the CTC information created in this way. FIG. 5B shows a case where a failure occurs in the track circuit device, and is an example of a failure of the power supply system that supplies electricity to the track circuit. When the electricity supplied to the track circuit device power supply 30 cannot be supplied due to a failure of the power supply system (including lightning strike), no current flows in the rail circuit, so the magnetic flux of the train detection relay 31 disappears, resulting in a relay switch. 32 is turned off. That is, the train centralized control device 1 tracks the train as CTC information that means “track circuit drop = OFF state” indicating the presence of the train.
It is transmitted to the control computer 2. FIG. 5C is a table summarizing the relationship between the track circuit states and the CTC display information in (a) and (b) above. The CTC display information is "dropping" when "no train" and "falling" when "train exists" or "equipment failure (power failure)" as the state of ground equipment.

Next, with reference to FIGS. 6 to 8, the relationship between the actual traveling of the train on the rails and the track circuit on the train tracking / control computer 2 will be described. 6 to 8, the hatched portion of the track circuit on the train tracking / control computer 2 indicates the falling state of the track circuit indicating the presence of the train, and the white part indicates the track circuit indicating that the train is not present. Represents the uplifted state. Here, the track circuit in which the last part of the track to be tracked is located is called a "reference track circuit", and the connection of the track circuits in which the train to be tracked progresses is called a "track link".

FIG. 6 shows the relationship between actual train travel and track circuit information on the train tracking / control computer. Figure 6
In (a), when the last part of the train actually exists in the track circuit 40, the train tracking / control computer 2 recognizes the track circuit 40 as a reference track circuit, and the track circuit checking linkage of the train is used. The on-rail links 46 to 50 are recognized as certain on-rail links. As the train runs,
The state shifts to that shown in FIG. Since the head car of the train has entered the track circuit 41, the track circuit 41 is in a falling state. When the train progresses further, the state shown in FIG. In this state, the train no longer exists from the track circuit 40 on which the last part of the train was located, so the track circuit 40 moves up.
That is, the reference track circuit 40 is lifted. When the reference track circuit 40 is lifted, the train tracking / control computer 2 causes the track circuits 41, 42, 43, 44, 45 linked to the on-track lines of the trains on the reference track circuit 40.
Are sequentially checked from the reference track circuit 40 to detect a falling track circuit. In the case of FIG. 6 (c), the track circuit 41 is first checked by the elevation of the reference track circuit 40, and as a result, the track circuit 41 has dropped,
The track circuit 41 is recognized as the reference track circuit on which the last part of the train is located, the information of the reference track circuit is updated, and the updated track circuit information file 4 is stored. Further, the track circuit 44 of FIG. 6 (c) represents a case where the track circuit indicating the presence of the train on the train tracking / control computer 2 is dropped due to a failure of the track circuit device or the like. When the train tracking / control computer 2 receives the drop notification of the track circuit 44, the train tracking / control computer 2 uses the reference track circuit 41, the train length, the travel prediction data, and the like of the train that is linked to the track circuit 44 that has fallen on the track. The rationality of the drop information of the track circuit 44 is judged. in this case,
As a result of the rationality judgment, it recognizes it as illegal fall information of the track circuit, and issues an alarm output, display notification, etc. to the dispatcher. In addition, in FIG. 6C, when the train tracking / control computer 2 receives the lifted state of the track circuit 41 despite the presence of the train, it is similarly recognized as incorrect lifted information of the track circuit. Then, an alarm output and display notification are given to the ordering staff.

7 and 8 show the relationship between the route opening direction and the on-rail link. FIG. 7A shows the traffic signal 5 in a normal state.
1 represents the relationship between the displayed name, the route opening direction, and the on-rail link. Now, the train 68 approaches the A station 50, and the track circuit 5
When you are on line 9, the train tracking / control computer 2
In order to allow the train 68 to enter the A station line 2 on the basis of the timetable file 3, the “RD
1 ”(RD1: route name to track 2) is requested. This route output request is transmitted to the admission signal 51 via the central train control device 1, and the admission signal 51 causes the “RD
1 ", that is, the route to A station line 2 is opened. continue,
The route opening state of the entrance signal 51 is transmitted to the train tracking / control computer 2 as CTC information via the train centralized control device 1. Train tracking / control computer 2
When this CTC information is acquired, the traffic signal name, in this case, "RD1", corresponds to the traffic signal 51 in the traffic signal information file 5.
Is updated, and the route link information file 6 is also searched from the traffic signal name to create the on-rail link track circuit of the train and store it in the on-rail link track circuit file 7. This state is shown in FIG. 7A when the train tracking / control computer 2 recognizes the train. Numerals 53 to 57 are on-rail links indicating on-rail track circuit inspection track circuits of the train 68, and are on the RD1 side of the traffic signal 52 in the opening direction, that is, A station 2
On-line links 53 to 57 are set to the numbered line.

FIG. 7 (b) shows a state in which electricity is no longer sent to the track circuit due to some failure in the power supply system for supplying electricity to the track circuit immediately after the on-line link is established in FIG. 7 (a). Represents When electricity is not supplied to the track circuit, as shown in FIG. 5, the rail current disappears, the magnetic flux of the train detection relay 31 disappears, and the relay switch 32 is opened. As a result, the train tracking / control computer 2 , CTC information is obtained as track circuit drop information equivalent to the presence of a train. Therefore, the train tracking / control computer 2 shown in FIG.
All of the track circuits 58 to 67 recognized above are in a falling state. The failure of the power supply system cuts off the supply of electricity to the running train, so the train loses its self-propelled ability,
Make an emergency stop. However, trains running at high speed require a certain amount of stopping distance to stop, so when the failure of the power supply system occurred, the failure of the track circuit where the train was located and the power supply system recovered. Sometimes the track circuits on which trains are located do not necessarily match. The higher the train is running, and the closer it is to running inside the station yard, the track circuits after failure recovery will hardly match. FIG. 7B shows a failure of the power supply system immediately after the on-rail link is established, and the train 68 required a stop distance. Therefore, the train entered the A station line 2 where the route was opened and stopped. It shows the state of being done.

FIG. 8 shows the operation of the train tracking / control computer 2 when the power supply system failure is recovered. When the power supply system is restored, the track circuit device is supplied with electricity again. In the track circuit to which electricity is supplied, the track circuit in which the train is not present generates magnetic flux in the train detection relay and the relay switch is turned on. In the track circuit, the relay switch of the train detection relay remains in the OFF state, the track circuit is short-circuited, and the track circuit drops, and this information is transferred to the train tracking / control computer as CTC information via the central train control device 1. 2 is transmitted. When the train tracking / control computer 2 detects from the received CTC information that the reference track circuit 59 before the failure of the power feeding system has risen, it checks the track circuit based on the on-rail links 53 to 57. First, the upgraded standard track circuit 59
The track circuit 60 which is the track circuit of the on-rail link destination is checked. Since the track circuit 60 is in a state in which no train exists, that is, the track circuit is in a raised state, the track circuit 61, which is the next on-rail link destination track circuit, is checked. Like the track circuit 60, the track circuit 61 is also in a state in which the track circuit is lifted, so that the track circuit 65, which is an on-track link track circuit, further ahead.
To check. Since the track circuit 65 is in the falling state due to the presence of the train 68, the track tracking
The control computer 2 determines that the tail end of the train 68 is in the track circuit 65, updates the information using the track circuit 65 as a reference track circuit, and stores it in the track circuit information file 4. In this way, when the reference track circuit is lifted, the on-track link track circuit is checked in order from the reference track circuit, and when the track circuit in the falling state is detected, the track circuit is determined as a new reference track circuit, The on-rail track circuit information file 4 is updated and stored. As a result, it is possible to promptly and automatically determine the in-rail position of the train after the failure recovery and the train concerned.

Next, referring to FIG. 9 to FIG.
The processing flow when the control computer 2 acquires the drop information of the track circuit as the CTC information and when it acquires the uplift information of the track circuit will be described. 9 and 11
Shows a processing flow when the track circuit changes from a lifted state to a dropped state. In FIG. 9, step 1
Then, the dropped track circuit is searched for presence / absence of an on-rail link, and it is determined whether or not the track circuit has fallen illegally.
Here, it is judged that the drop of the track circuit without the on-rail link is the change information of the track circuit which is not related to the running of the train, and the out-of-rail process in step 5 outputs an alarm as an illegal drop of the track circuit, display, etc. To execute. If the track circuit has an on-rail link, it is considered that the track circuit is due to the train entering the track circuit. Therefore, in Step 2, the change in the track circuit is within the effective range of the track circuit from the reference track circuit. It is determined whether there is any. FIG. 11 shows a detailed processing flow of the effective track circuit determination processing in step 2 of FIG. In step 2-1, for the trains that are linked to the track circuits that have fallen, the No. of Table 2 (FIG. 4) is set. 1
The on-rail train table 4-1 is searched using the on-rail train table pointer, and No. 1 in Table 1 (FIG. 3) is searched. The train number of No. 1 in Table 1 is extracted based on the train number extracted in step 2-2. 2 From the reference track circuit, take out the track circuit number where the last part of the train number is located. In step 2-3, the on-rail link track circuit is extracted from the on-rail link track circuit file 7 based on the extracted reference track circuit. Then, in step 2-4, among the extracted on-rail link track circuits, the on-rail link track circuit file 7 is used to find the track circuits on which the train can be on-track, based on the train length, running prediction, and the like.
Take out from. Next, in step 2-5, it is determined whether or not the track circuit that has fallen corresponds to a track circuit in which the train can stay in the train. If they do not match, it is determined that the track circuit has fallen except for the entry of the train, and the process returns to step 2 in FIG.
In step 3 of FIG. 9, the result of step 2 is determined, and if the dropped track circuit is in the effective range of the on-rail circuit, the track circuit on-rail process is performed in step 4, and the on-rail circuit information file 4 is updated and stored. If the dropped track circuit is outside the effective range of the track, the warning signal is output and displayed as an incorrect track circuit change in the track circuit on-line process in step 5.

FIG. 10 and FIG. 12 show a processing flow when the track circuit that has been dropped is changed to the lifted state. Figure 1
When the track circuit that has fallen is lifted at 0, in step 100, the track circuit tracking table 4-2 corresponding to the lifted track circuit No. 4 to No. 2 in Table 2. 5 or No. 6
The link track circuit information is taken out and the presence or absence of the on-track link of the upgraded track circuit is searched. As a result of the search, if the on-rail link is not recognized, it is determined that the track circuit is not lifted due to the passage of the train, and in step 150, an illegal track circuit lifting process is executed. If the on-line link is recognized, in step 110, No. 2 in Table 2 is selected. No. 1 in Table 1 is searched using the in-rail train table pointer 4-1. 1 Take out the train number. In step 120, No. 1 in Table 1 is selected. 2 From the reference track circuit, the track circuit number in which the last part of the train number is located is taken out, and in step 130, the track circuit number that was lifted and No. 1 in Table 1 are taken out. 2 Compare the track circuit number of the reference track circuit. As a result of the comparison, if the enhanced track circuit number and the reference track circuit number match, in step 140, the reference track circuit update process is performed. If they do not match, it is determined that the track circuit other than the reference track circuit has been expanded, and in step 150, the processing for increasing the incorrect track circuit is executed. If the track circuit has fallen illegally, the illegal state of the track circuit is released in step 160.

FIG. 12 shows a detailed processing flow of the reference trajectory circuit update processing of step 140 of FIG. In FIG. 12, in Step 140-1, the track circuit tracking table 4-2 of Table 2 is obtained in order to retrieve the on-track link track circuit number.
No. 5 or No. Search for 6-link track circuit information. In step 140-2, the on-rail state of the on-rail link destination track circuit is searched based on the link track circuit information of step 140-1. The track circuit tracking table 4-2 corresponding to the linked track circuit is taken out, and No. 2 in Table 2 in the taken out table is taken out. 3 Refer to the information on the status of existing lines. In step 140-3, No. If the 3-rail status is the "falling" status, the reference track circuit is updated in step 140-5. No. 3 If the line status is not "falling",
In step 140-4, the track circuit to be checked next is set, and the process returns to step 140-2. This process is repeated until a drop in the track circuit is detected in step 140-3. In step 140-5, No. 1 in Table 1 of the on-rail train table 4-1 is selected. 2 Update the reference track circuit information to the linked track circuit number. That is, the track circuit in which the fall is detected is determined as the track circuit in which the last part of the train is located, that is, the reference track circuit, and the reference track circuit information is updated and stored. As a result, the on-track track circuit and train number of the train can be determined. Step 140
At -6, the range of track circuits that can be present from the track circuit that has become the new reference track circuit is calculated, and step 140-7
Track circuit tracking table 4 of the track circuit
No. 2 in Table 2 in Table-2. 5 or No. The link track circuit information of 6 is updated, and the on-line link of the lifted track circuit is disconnected. This ensures that the track circuit is always checked in the traveling direction from the track circuit where the last part of the train is located by disconnecting the on-track link of the original reference track circuit. This enables on-track links for subsequent trains, and keeps the track circuit inspection range fine.
