DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a train signal system in a railway security system having an automatic train control device, and more particularly, to a method in which a succeeding train follows a preceding train and continuously enters a switch. The present invention relates to a train signal system that is enabled.

[0002]

2. Description of the Related Art In a conventional interlocking device, a route is formed, and in order to advance the signal display, a train is not present in the route and a switch in the route forms a route. It needs to be turned in the direction needed to do so. Therefore, when a train is on the track, the signal cannot be made to proceed, so that only one train can enter the one track with the conventional interlocking device.

As a prior art for permitting a plurality of trains to enter one route, there is Japanese Patent Publication No. 7-41840, for example. In this publication, the interlocking device ignores the on-rail state of the train in the course because the safety of train running is ensured by wireless high-precision train position detection and also by wireless train interval control. To set the course. As a result, even when the preceding train is already on the route, the interlocking device can give permission for the following train to enter the route, and can control the train running by reducing the train interval. .

[0004]

However, in the above-mentioned prior art, no consideration is given to the continuous entry of a plurality of trains into the switch, and the train running is controlled by reducing the train interval. Also have limitations. In other words, in order to allow multiple trains to enter a single point simultaneously, it is important to control the direction and lock of the point, and after the first train leaves the point, If the lock is unlocked, the safety of the running of the following train is not guaranteed, and if the lock is locked after the train leaves, the competing route cannot be set. However, there is no solution in the prior art.

[0005] It is an object of the present invention to provide a train signal system that allows a plurality of trains to continuously enter a switch.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a route control device for requesting route setting and route cancellation in accordance with a train operation condition, In response to a request for setting and canceling a route, in a train signal system including an interlocking device that checks the on-rail status of the train and the state of the switch, and sets and cancels the route, a plurality of trains When entering the switch, if the turning requests of the switch in the same direction continue, the locks of the switch remain locked until the plurality of trains have passed through the switch. Switch means for changing the position and route control for permitting the plurality of trains to enter the switch after confirming that the switch remains locked. Means.

[0007] According to the above configuration, when a plurality of trains enter the switch, if the request for turning the switch in the same direction continues, the switch remains locked. because there is,
A plurality of trains can enter the switch continuously.

[0008] In configuring the above-mentioned train signal system, the following elements can be added. (1) A reception route request storage medium for receiving a plurality of route setting and cancellation requests including requests for the same route and competing routes from the route control device, and storing the received requests. (2) A switch state storage medium for storing a plurality of switch requests for the switch for each switch. (3) The switch changing means refers to a plurality of switch requests of the switch stored in the switch state storage medium, and determines the oldest change request and the direction of the switch. If they do not match, they have the function of turning and locking the switch, turning the switch in a different direction, and not unlocking the switch until there is no request to switch the switch. (4) When the route control means confirms the lock of the switch, the switch request in the different direction between the switch request of the switch for setting the route and the oldest switch request is issued. However, when the switch is locked, the switch has a function of determining that the switch is locked. (5) The route control means, when the train passes through the switch, transmits the switch request of the switch, which is requested when setting the route for the train, to the switch status storage medium. It has a function to delete from.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an overall configuration diagram of a train signal system according to the present invention. As shown in FIG. 1, a train 103 is located before and after the switch 105. Here, the plurality of trains 103 and the courses 112 are distinguished by adding a and b and subscripts. On the ground side, a ground control device 101, a ground-side wireless transmission device 02, an interlocking device 1
09, a course control device 110 is provided. Hereinafter, the description will be given in order according to the flow of the processing at the time of the route request.

The train 103 calculates the current position of the train 103 by a method such as accumulating the speed and calculating the travel distance, and creates position information 107 which is information indicating the current position of the train. 107 is wirelessly transmitted to the ground-side wireless transmission device 02. The format of the position information 107 is out of the scope of the present invention, and will not be described.

[0011] The terrestrial-side wireless transmission device 102 transmits the position information 10
7 and the current position of the train 103 is recognized.
Calculate the stop limit 104 for 03. Stop limit 10
Reference numeral 4 denotes a limit point at which the train can safely travel without danger of the train colliding with another train or derailing. For the calculation of the stop limit 104, the position of the other train recognized by the ground control device 101, and the
Information such as the opening information of the route 112 and the direction of the switch 105 are used. The search is performed from the position of the train 103 until an unopened track end in front of the train or an obstacle that hinders the running of the train such as a preceding train is found. If there is a branch, it is determined which of the branch destinations to search from the direction of the switch 105. The position of the trouble found as a result of the search is set as the stop limit 104.

The ground control device 101 calculates the calculated stop limit 1
04, and generates control information 106 that is information for controlling the running of the train, and transmits the generated control information 106 to the train 103 via the ground-side wireless transmission device 102. Since the format of the control information 106 is outside the scope of the present invention, the description is omitted.

As described above, since the stop limit 104 is calculated with reference to information such as the path opening status and the direction of the switch, the stop limit 104 is determined by the control method of the path of the interlocking device 109 and the switch. The value changes. The interlocking device 109 receives the route request information 111 from the route control device 110, and starts controlling the requested route. The route request information 111 includes a route to be requested and a route request serial number. The format of the route request information 111 will be described later. The link device 109 receives a plurality of pieces of route request information 1 for the same route or routes competing with each other from the route control device 110.
11 can be accepted. Interlocking device 1
09 sequentially processes the received plurality of route request information 111, and when there is no route competing with the route during the route request of the same route, the route is displayed even after the train enters the route. Leave as is. If there is a route competing with the relevant route during the route request for the same route, after entering the train inside the relevant route, the relevant route is set to the stop indication, and the route is switched by the same processing as the conventional route-based lock. After unlocking the device and performing the switching process of the switch necessary for setting the competing route, the requested competing route is set as the progress indication. Also, the interlocking device 109
Is the ground control unit 1 for controlling the course and the switch.
From 01, the train position information 108 is received. The train position information 108 includes all train positions and train IDs that the ground control device 101 grasps. The format of the train position information 108 will be described later. The interlocking device 109 transmits the result of the route control to the ground control device 101 as route state information 113. Since the format of the route state information 113 is out of the scope of the present invention, the description is omitted.

A specific example will be described. In FIG. 1, when the train 103a and the train 103b enter the same path 112a, the switch 105 is locked in the same direction. The interlock device 109 is provided by the route control device 110.
Two pieces of route request information 111 of the same route 112a are received,
As shown in FIG. 1, even after the train 103b has entered the inside of the course 112a, the course 112a is kept as it is. When the train 103a enters the route 112b and the train 103b enters a route different from the route 112a, the switch 10
5 will lock in different directions. After the train 103b enters the inside of the route 112a, the route 112a is set to the stop indication, the switch 105 is changed, and then the route 112b is set to the progress indication. The details of the course setting / rearranging / locking process and the switchover process will be described later.

By constructing the whole system as described above, the trains 103 are successively connected to the switches 105 in the same direction.
When the vehicle enters, the train 103 can enter the switch 105 without moving and closing the end of the switch 105 without the stop limit, and the train interval can be reduced.

FIG. 2 is a block diagram showing the internal configuration of the interlocking device 109. Inside the interlocking device 109, a ground control device communication unit 201, a train position conversion unit 202, a route control unit 203, a switch unit 204, a switch / track state storage unit 205, a route control unit communication unit 206, a received route request storage unit 207, a route state information creating unit 208, and a local facility device communication unit 209 are provided. Hereinafter, the description will be given in order according to the processing flow of each cycle of the interlocking device 109.

In FIG. 2, a ground control device communication unit 201
Receives the train position information 108 including the train position and the ID from the ground control device 101, and passes the train position information 108 to the train position conversion unit 202. The train position conversion unit 202 converts the representation of the train position of the ground control device 101 into the representation of the train position of the linkage device 109 when the representation of the train position of the ground control device 101 and the representation of the train position of the linkage device 109 are different. Then, the converted train position is passed to the route control unit 203 and the switch device switching unit 204. When the expression of the train position of the ground control device 101 and the expression of the train position of the interlocking device 109 are the same, the train position conversion unit 202 is not necessary, and the train position conversion unit 2
A configuration without 02 is also conceivable.

The route control unit 203 includes a train position conversion unit 20
The route control is performed based on the train position received from Step 2 and the information stored in the received route request storage unit 207 and the switch / track state storage unit 205. The course control includes setting, locking, and restoring the course. At the time of setting the course, only the lock of the switch is confirmed, and the state of the train on the inside of the course is not a condition for setting the course. Therefore, the course can be set if the switch required for the course configuration is locked in the correct direction. In the course setting process, if there is a switch to be changed, the switch request is passed to the switch changing unit 204. The change request shall include the direction to change and the route request serial number of the relevant route. The route locking process is performed when the train enters the inside of the route, and the ID of the train that entered the inside of the route is associated with the route request serial number of the route request. A train ID used in the train position information 108 received from the ground control device 101 is used. As with the conventional interlocking device, the train is locked while the train is in the locked section, and unlocked when the train leaves the locked section. The route relocation process is performed when the train leaves all the locked sections, unlocks all the switches that are locked with the relevant route request serial number of the relevant route, and also unlocks the status of the route. And When unlocking the switch, an unlock request is passed to the switch conversion unit 204. It is assumed that the unlock request includes the route request serial number of the relevant route. Details of each process will be described later. The route control unit 203 reflects the result of the route control on the switch / track state storage unit 205.

The switch changing unit 204 includes a route control unit 203.
Switch request and switch / track state storage unit 2
Based on 05 and the train position received from the train position conversion unit 202, the switch control of the switch is performed. The switch unit 204 can receive a plurality of switch requests from the route control unit 203. If there are consecutive requests in the same direction,
When the train passes through the switch, the switch remains locked. Unlock the switch when it is necessary to switch to a different direction. After the switch is complete, lock the switch again. Details of the switchover process will be described later.

The switch / track state storage unit 205 manages, as the state of the switch, the direction of the switch, the presence or absence of the lock, and a plurality of conversion requests. As the route state, it manages whether the route is the progress indication or the stop indication, and the state of the route lock corresponding to each route request serial number. The data structure of the switch / track state storage unit 205 will be described later.

The route control device communication unit 206 receives the route request information 111 from the route control device 110 and stores it in the received route request storage unit 207. The received route request storage unit 207 stores the route ID and the route request serial number of the received route request.

The route condition information creating unit 208 creates route condition information 113 with reference to the switch / track condition storage unit 205 and transfers the route condition information 113 to the ground control unit communication unit 201. The ground control device communication unit 201 having received the route state information 113 transmits the route state information 113 to the ground control device 101.

The on-site equipment communication section 209 receives a change request from the switch changing section 204 and issues an instruction for changing to the switch. Further, the on-site equipment device communication unit 209 takes in the orientation of the on-site switch as the status of the on-site equipment and reflects the orientation on the on-point switch / track state storage unit 205.

By configuring the interlocking device 109 as described above, the ground control device 10 can respond to a plurality of route requests.
In this case, it is possible to control the switch and the course while referring to the train position grasped by the trainee 1. If the same course is continuously requested, the course is kept as it is and the competing course is maintained. If is required, the course can be a stop announcement.

FIG. 3 shows a processing flow at the time of switching of the switch of the switch 204. Pointer conversion unit 20
Reference numeral 4 controls the switching of the switch by executing the processing flow of FIG. 3 every cycle.

Step 301: It is checked whether or not a change request of the switch has been received from the course control unit 203. If a conversion request has been received, the process proceeds to step 302. If the conversion request has not been received, the process proceeds to step 303.

Step 302: The change request of the switch confirmed to have been received in step 301 is added to the end of the change request list. The conversion request includes the orientation of the switch,
It is assumed that the corresponding route request serial number is included. The structure of the conversion request list will be described later. Then, the process proceeds to step 303.

Step 303: It is checked whether or not a request to unlock the switch has been received from the route control unit 203. If an unlock request has been received, the process proceeds to step 304. If the unlock request has not been received, the process proceeds to step 305.

Step 304: Since the unlock request of the switch confirmed to have been received in step 303 contains the corresponding route request serial number, the conversion request including the relevant route request serial number from the conversion request list. Search for and delete.
Then, the process proceeds to step 305.

Step 305: The state of the local switch is checked by referring to the switch / track state storage unit 205, and it is checked whether it matches the direction of the head of the switch request in the switch request list. If so, the process proceeds to step 306. If not, the process proceeds to step 307.

Step 306: The state of the switch is set to the locked state, and the processing is terminated.

Step 307: Based on the train position received from the train position converter 202, it is checked whether or not the train is within the range of the check lock of the switch. If there is, the process ends. If not, the process proceeds to step 308.

Step 308: In the switch / track state storage unit 205, the switch is set to a state in which the switch is being changed to the requested direction, and the local equipment communication unit 209 switches the local equipment. A conversion request is issued to the device, and the process ends.

FIG. 4 shows a processing flow of the course control unit 203 when setting a course. Step 401: Steps 402 to 4 in the route request information 111 stored in the received route request storage unit 207 for a route whose route status is not a progress indication.
08 is performed. If the process is performed for all routes whose route status is not the progress indication, the process ends. Otherwise, go to step 402.

Step 402: The processing of steps 403 to 407 is performed for all the switches in the course. If the process has been performed for all the switches, the process proceeds to step 408. Otherwise, the process proceeds to step 403.

Step 403: It is checked whether or not the switch request having the route request serial number of the route request is in the switch request list of the switch. If so, it is determined that a conversion request has already been issued, and the process proceeds to step 405. If not, it is determined that the conversion request has not been issued, and the process proceeds to step 404.

Step 404: switch unit 204
Then, a request for turning the switch is issued so that the switch is turned in a direction necessary for forming the course.

Step 405: Referring to the change request list of the switch, whether there is a change request having a different direction between the change request at the head of the change request list and the change request having the route request serial number of the route request. Find out. If not, it is determined that the switch remains locked in the same direction.
Proceed to 06. If there is, the switch judges that the lock will be locked in the reverse direction before the route of the route request is set, and proceeds to step 407.

Step 406: The orientation of the switch of the local facility is checked by referring to the switch / track state storage unit 205. The point of the local equipment's switch coincides with the direction requested for conversion,
If the switch is in the locked state, the switch remains locked in the same direction. Therefore, it is determined that the switch is locked, and the process proceeds to step 402. .

Step 407: Since the switch is locked in the reverse direction before the route of the route request is set, it is determined that the lock has not been made from the viewpoint of the route request. Proceed to step 402.

Step 408: If all the switches are locked, that is, if step 402 is terminated without proceeding to step 407, proceed to step 409.

Step 409: Since all the switches in the route are locked in the requested direction, the route is displayed as progress and the route request serial number is added to the route request list of the route. Then, the process proceeds to step 401.

FIG. 5 shows an example of the route request list used in step 409. It is assumed that the route request list is provided for each route, and that the route request serial number is in the list while the route is locked after the progress notification is made. When the pathway lock is unlocked, it is deleted from the list. The route request list includes a route request serial number, a route state corresponding to the route request, and a corresponding train I.
D. At the time when the announcement was advanced, the train I
D is blank. The process of associating the route request serial number with the train ID is performed when the train enters the route in the route relocation process. The details of the course relocation processing will be described later.

In FIG. 5, the route request serial number of the route request information 111 for the train of train ID 1 is 1, the route request serial number of the route request information 111 for the train of train ID 2 is 2,
The route request serial number of the route request information 111 for the train with the train ID 3 is 3. Then, when the trains with the train IDs 1 and 2 enter the inside of the course, the course request list has the form shown in FIG.

A configuration is also conceivable in which the route control device 110 associates the route request serial number with the train ID when a route request is made. However, when the route request serial number and the train ID are associated with each other by the interlocking device at the time of route relocation, the system can be configured only by changing the interlocking device, using the conventional route control device 110 almost as it is.

FIG. 6 shows a processing flow of the route control section 203 at the time of route relocation. Step 601: Steps 602 to 6 are performed on the route indicated as progress by referring to the state of each route.
06 is performed. If the process is performed for all the routes indicated by the progress, the route reversion process ends. Otherwise,
Proceed to step 602.

Step 602: The processes of steps 603 to 606 are performed for all the track circuits in the course. If the process is performed for all the track circuits in the course, the process proceeds to step 601. Otherwise, the process proceeds to step 603.

Step 603: It is checked whether or not a train is on the track circuit. If the train is on the line, the process proceeds to step 604;
Proceed to 2.

Step 604: The route request list of the route is searched, and it is checked whether or not the ID of the train on the track is included in the route request list. If it is not included, it can be determined that the train has entered the inside of the course and it is necessary to return to the course, so the process proceeds to step 605. If it is included, it can be determined that the route request serial number corresponding to the train has already been restored, and the process proceeds to step 603 without doing anything.

Step 605: The course is relocated, the stop is indicated, and the process proceeds to Step 606.

Step 606: Search the route request list of the route for the route request serial number whose route status is indicated as progress, and set the route status to the route locked state. further,
The train ID corresponding to the route request serial number is stored in the step 604.
And the train ID determined not to be included in the route request list, and the route relocation process ends.

FIG. 7 shows a processing flow of the course control unit 203 when the course is locked. Step 701: With reference to the route request list, a route request serial number whose route state is locked is searched, and the train ID corresponding to the route request serial number is stored in the intra-route train list. Then, the process proceeds to step 702.

Step 702: Similar to the conventional interlocking device, a route lock process is performed for each route division lock. The processing from step 703 to step 708 is performed for each track lock.
The route division is processed in order from the near side with respect to the traveling direction of the train. If the process is performed for all the route divisions, the process proceeds to step 709. Otherwise, step 7
Go to 03.

Step 703: The process of step 704 is performed for all the track circuits in the route section. If the process is performed for all the track circuits, the process proceeds to step 705. Otherwise, go to step 704.

Step 704: The train ID existing on the track circuit is searched, and the train existing on the track circuit is deleted from the on-track train list. Then, the process proceeds to step 703.

Step 705: If the list of trains in the route becomes empty, it can be determined that all the trains on the list of trains in the route are on or near the track circuit.
Since the route and the switch cannot be unlocked any more, the route locking process ends. If the track inner track circuit list is not empty, the process proceeds to step 706.

Step 706: The fact that the intra-track train list is not empty means that the trains remaining in the intra-track track circuit list are present on track circuits deeper than the relevant track circuit. Therefore, the route division lock can be released for the remaining trains in the intra-route train list. Therefore, the processes of step 707 and step 708 are performed for each track circuit in the route section. If the processing is performed for the track circuits in all the route sections, the above-described step 7
Go to 02. Otherwise, the process proceeds to step 707.

Step 707: The process of step 708 is performed for each train remaining in the on-track train list in order to unlock the switch in the track circuit. If the process is performed for all the trains remaining in the on-track train list, the process proceeds to step 706. Otherwise, go to step 708.

Step 708: The path request serial number corresponding to the train ID is searched from the switch request list of the switch in the track circuit, and is deleted, so that the solution of the switch corresponding to the train ID is determined. Do the lock. And step 70
Proceed to 7.

Step 709: If the list of trains on the route becomes empty after searching for the trains on all the route divisions, it can be determined that all the trains on the list of trains on the route are present in the route. Since the route cannot be unlocked, the route lock process ends. If the in-route train list is not empty, the process proceeds to step 710.

Step 710: If the list of trains in the route is not empty, there is a train passing through the section of the route division lock, so that the route lock can be unlocked for that train. Step 7 for each train in the train list
The processing from step 11 to step 713 is performed. When the process is performed for all the trains in the train-in-route train list, the route locking process ends. Otherwise, the process proceeds to step 711.

Step 711: Since the processing of the route request serial number corresponding to the train has been completed, the route request serial number corresponding to the train is deleted from the route request list, and the process proceeds to step 712.

Step 712: In order to unlock all the switches in the unlocked route, the process of step 713 is performed for all the switches in the route. If the process is performed for all the switches in the course, the process proceeds to step 710. Otherwise, the process proceeds to step 713.

Step 713: The route request serial number corresponding to the train ID is retrieved from the switch request list of the switch and deleted to unlock the switch corresponding to the train ID. Then, the process proceeds to step 712.

FIG. 8 shows a format of a switch request list of the switch used by the route control unit 203 of the switch unit 204. In the change request list, the route request serial number and the change direction are stored in the order of request. When the route control unit 203 unlocks the switch, the route request serial number is deleted from the conversion request list.

FIG. 9 shows an example of the format of the route request information 111. As shown in FIG. 9, the route request information 111 includes a route request information serial number, a route request type, and a requested route ID. The route request information serial number is a number assigned by the route control device 110 so as not to be duplicated in the route request information 111 requesting route setting. At the time of a route setting request, a new number that does not overlap with other route setting requests is assigned. When canceling the route setting request, the route request serial number of the route request information 110 to be canceled is set as the route request serial number. Two types of route request types, “setting” and “cancellation”, can be set. In the requested route ID, the ID of a route for which a setting request or a cancellation request is made is set.

FIG. 10 shows an example of the format of the train location information 108. As shown in FIG. 10, the train position information 108 includes a train ID, a train position, and a direction, and includes information on all trains recognized by the ground control device 101. In FIG. 10, the train position is expressed in kilometers, but an expression based on the track circuit or the like may be used.

FIG. 11 shows a switch / track state storage unit 20.
5 shows the structure of FIG. As shown in FIG. 11, the switch state first includes a switch name, a switch orientation, a locked state, and a change request list. The orientation of the switch is updated by the local equipment communication unit 209 every period by taking in the status of the local equipment. The locked state includes a locked state and an unlocked state, and is updated by the switch unit 204. The switch point change list is a list of path request serial numbers corresponding to the change request direction, and is updated when the path control unit 203 issues a switch request of the switch when setting a path. Next, the route status includes a route ID, a present status, a locked status, and a route request list. The present takes the state of "progress" and "stop". The locked state takes the states of “locked” and “unlocked”. The route request list is a list of route request serial numbers in a state from when the progress notification is made to when the route is unlocked.

If the route for which the setting request has been made is canceled, if the route has not been set, the reception route request storage unit 207
Can be realized by deleting the route request serial numbers from the change request list of all the switches. When the route is already set, the route request serial number is deleted from the reception route request storage unit 207, the change request list of all the switches, and the route request list of the route, and the conventional interlocking device is deleted. This can be realized by performing the same processing as the return of the course. The process of pulling back the path of the conventional interlocking device is out of the scope of the present invention, and therefore will be omitted.

As described above, in the present embodiment, the interlocking device 109 receives the setting request for the same route or the competing route from the route control device 110, and
Route control is performed based on the train ID and position received from 01. As a result, when a train successively enters a switch in the same direction, the train can enter the switch with the moving blockage realized without making the switch end the stop limit. It is possible to reduce train intervals.
Specifically, in response to a plurality of route requests, a change request is sequentially issued to the switch. Each switch saves the switch request in a list, and the switch converter 204 determines whether or not the switch is necessary and whether the lock is possible with reference to the list. Perform control. The route control unit 203 stores the route requests in a list, and performs the process of setting, restoring, and locking the route while referring to the train position and the state of the switch grasped by the ground control device 101 in the order of the list. When the same route is continuously requested, the same request is continuously made for the switching request of the switch. Therefore, the switch conversion unit 204 keeps the switch in the locked state and the route control unit. Reference numeral 203 indicates that the switch is locked, so that the same route is kept as it is. When a competing course is requested, a change request in a different direction is continuously issued to the switch. Therefore, the course control unit 203 sets the switch when there is a change request in a different direction. The device is determined not to be locked, and a competing route cannot be configured, and the stop is indicated.

Further, in the present embodiment, the ground control device 101 uses the ground-side radio transmission device 102 to receive the position information transmitted wirelessly from the train 103 in order to grasp the position of the train. However, the position information may be received using a leaky coaxial cable.

Further, the interlocking device 109 is provided with the ground control device 10.
The train position information 108 received from No. 1 is used to search for a train ID located in the track circuit. Therefore, by using a track circuit that can receive messages from a plurality of trains, the train ID existing in the track circuit may be received from the track circuit, and the train position information 108 may not be received from the ground control device 101. .

That is, there is a certain degree of freedom in constructing the technology of the present invention. The configuration may be selected so as to be optimal for each line section.

[0074]

As described above, according to the present invention,
When multiple trains enter the switch, if the request for turning the switch in the same direction is continuous, switch the trains continuously while keeping the switch locked. You can enter the vessel.

Further, even when the preceding train is on a switch on the inside of the course, it is possible to make the following train enter the switch, thereby reducing the train interval. Thus, the efficiency and convenience of train operation are improved.
