Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to operation management of trains and vehicles (hereinafter collectively referred to as trains), train replacement work management, maintenance vehicles and maintenance work relations,
Or, it relates to a railway management system that manages emergency driving in an emergency. Specifically, in accordance with a given route setting request, a rolling track provided at a branch portion of a railway line (hereinafter referred to as a track). The present invention relates to an interlocking device that switches a machine to open a desired path and automatically performs an operation of displaying the opening of the path on a traffic light.

[Conventional technology]

In places where railway lines are complexly gathered and branched, such as inside railway stations, open the route and display the possibility of entering the route, such as turning machines, traffic lights and signs. A large number of devices (hereinafter collectively referred to as route control devices) are provided, and these are switched according to arrival, departure, passage, etc. of trains and maintenance vehicles (hereinafter collectively referred to as trains), and routes required by the train. Is being opened. The switching operation of these route control devices must be carried out promptly and appropriately in response to arrival, departure, passage, etc. of the train, and the train must be operated or passed efficiently. Moreover, there should be no mistake in the operation of these route control devices, and if only the attention of the operator was used to prevent the incorrect operation, there is a risk of incorrect operation as trains start and stop frequently. Although it occurs, the work efficiency does not increase. Therefore,
When the operation of the route control equipment is wrong, in order to eliminate the erroneous operation to secure the safety and to improve the work efficiency, interlock (locking lock) in advance to the operation relation of many related route control equipment. The interlocking device is set to set and the control operation is performed according to the setting.

That is, in the interlocking device, first, when the operator inputs data such as the starting and ending points of the train in accordance with the route setting request,
In response to this, it checks (checks) whether the related route has already been set and opened by another train, and after confirming that it has not been set, the rolling machine necessary to open the requested route. Is output in the predetermined direction. Next, it is confirmed that the predetermined route has been opened based on the conversion position signal output from the rolling machine, and this is displayed on the display panel of the interlocking device control panel. After setting the route in this way, the operation and work of other trains that obstruct the route are disabled, and in order to secure the route until the train passes, the chain is linked to the related rolling machines. Outputs a lock command. Then, using the track circuit detection means, confirm that no other train is on the route, switch the display of the relevant traffic signal to the "progress (blue)" side, lock it, and display it on the display panel. To do. Then, after the train has completed passing through a predetermined point on the set route, the lock of the rolling machine or the like is released. In this way, the operator can enter the data such as the starting and ending points of the train, etc., and the route will be automatically opened without conflict and the necessary display will be performed, so that erroneous operation etc. can be prevented. , Frequent train arrivals and departures can be handled efficiently.

As interlocking devices having such a function, conventionally, a relay-type interlocking device having interlocking control logic formed by a relay circuit and an electronic interlocking device using a microcomputer are known. In the former relay-type interlocking device, a lock is applied between the turning device and the traffic signal within the control target range and the traffic signals in consideration of all combinations, thereby covering the erroneous operation on the dangerous side and preventing the malfunction. It is basically to prevent. In addition, the route setting is performed by using the start / end lever push button or the signal lever, and the competition of the train route during the opening operation is eliminated by the route selection circuit or the lever relay circuit assembled by the relay circuit, and the relationship is changed. An indirect competitive judgment system is adopted, such as eliminating through a rolling machine by a machine lock or a route lock mechanism.

[Problems to be Solved by the Invention]

However, the relay type interlocking device has the following problems because the interlocking control logic is fixed and difficult to change because the interlocking control such as the lock is assembled by the hardware relay logic circuit. .

That is, since the interlocking control logic is composed of a relay circuit, the line wiring type can be changed, a signal can be added, or maintenance
There is a problem that it is not possible to flexibly deal with changes in the form of replacement work. For example, when designating a work range for maintenance / replacement work, setting / opening a route for a maintenance vehicle, or replacing work, two routes (opposite directions) that come from opposite directions with respect to the same rolling machine opening direction are used. Since the relay circuit is assembled based on the concept of mutual locking so that the opposite route) is not set at the same time, the route for maintenance / replacement work and the work range designation are fixed. Moreover, in order to realize those changes, the addition and change of the relay logic circuit are required, so that a great deal of labor and cost are required for the on-site wiring work and the function confirmation test.

On the other hand, the latter electronic interlocking device locks the switching machine and the traffic signal in the control target range and the traffic signal between them in consideration of all combinations, thereby covering the erroneous operation on the dangerous side, It is the same as the above-mentioned relay type in that the malfunction is basically prevented. In addition, the route setting is performed by using the start / end levers or signal levers as in the case of the relay system, and the elimination of train route conflicts during opening operations and the determination of oncoming route conflicts are replaced by software logic instead of the relay circuit. This is done by the spur file mechanism configured in. This spur file mechanism is an information file in which the track circuits are associated with each other in terms of the opening direction of the turning machine for each track circuit. Then, when the start point / end point information is input, the start point information is used as a key to search whether the route to the end point specified by the end point information exists in the spur file, and the route in the spur file is searched. Perform connection processing. When the specified route cannot be connected,
Alternatively, if another route has already been set, it is considered that there is no required route, and the route configuration is not possible is reported. When the route connection is established, then, based on the route, the opening direction (switching position) information of the relevant rolling machine is extracted from the connection state of the spur file and the rolling machine conversion control is performed. As a result, after all the related transfer machines have been normally converted, the transfer machine and track circuit unit in-use information are registered in the spur file. At the same time, the lock for each route division unit is performed on the route lock table. However, since this spur file has a control logic composed of a complicated mesh-like file, it is a relay-type for changing the line wiring type, adding a traffic signal, or changing the form of maintenance / replacement work. As in the case, there is a problem that it cannot be handled easily. That is, as described above, the work range for maintenance / replacement work is designated, the route of the maintenance vehicle is set / opened,
Or, the contents of the replacement work are fixed, and in order to realize those changes, it is necessary to add / change the spur file, so there is a problem that a large amount of labor and cost are spent on the data creation work and the function confirmation test. .

In addition to the flexibility for changing the interlocking control conditions,
According to the conventional interlocking device, since the logic of interlocking control must be individually configured according to the line wiring shape in the station yard to be applied, the control logic is largely influenced by the wiring type peculiar to each station, There is a problem that it is difficult to standardize the control logic and then modify it.

In particular, according to the above-mentioned conventional technology, by the locking logic of the fixedly set rolling machine such as the relay circuit or the spur file, the rolling machine according to the route already set is not changed, Since the competition determination of the route of the train is indirectly performed, the logic of the competition determination becomes complicated depending on the wiring shape and the like, and the construction of the interlocking control logic is extremely complicated. In addition, when trying to set a new route or maintenance work range, it is necessary to check the related relay circuits and spur files as a whole to avoid conflicts in the route and change them if necessary. is not.

Therefore, it is an object of the present invention to provide an interlocking control device capable of simplifying and clarifying the logic of competition judgment and easily setting a new course or the like.

[Means for Solving the Problems]

To achieve the above object, the present invention is an interlocking device comprising a computer, which computer comprises a track circuit reservation table (12) and route setting request input means (41, 3).
1), route reservation check means (21), and route locking means (2
4) and have.

Here, in the track circuit reservation table (12), reservations for the course setting and maintenance replacement work range of the train are registered in track circuit section units, and the track circuit section detects the in-rail position of the train. It is a section of the track circuit divided and set along the track. The route setting request input means (41, 31)
The track circuit section included in the route of the train is designated and the route setting request is input. Route reservation check means (21)
Is input to the route setting request input from the route setting request input means (41, 31), and in response to the input, refers to the track circuit reservation table (12) and is included in the route related to the route setting request. For all the track circuit sections to be set, it is judged whether or not the reservation of the setting of the track and maintenance replacement work range of other trains is registered, and the judgment of the track conflict is made. It outputs a route opening command in response to a setting request. The route locking means (24) receives the opening command output from the route reservation checking means (21), and responds to the opening command, for all track circuit sections of the route for the route setting request, the track circuits. It is assumed that the reservation for course setting is registered in the reservation table (12).

Further, it is preferable that the computer of the interlocking device described above has a turning control means (22) for controlling the conversion of the turning machine. In this case, the route setting request input means (41,3
In 1), the route setting request is input by designating the starting point, the ending point of the train, the track circuit section in the middle, and the related rolling machine and the changing direction, and the rolling control means (22).
Is a route setting request input means (41, 31) for specifying a turning machine and a turning direction, and a route reservation checking means (2
With the opening command output from 1) as an input, in response to the opening command, the rolling machine is turned to the designated turning direction, and the reservation command for the route setting according to the route setting request is output. To do. And route locking means (24)
The input is a reservation command output from the rolling control means (22), and when the reservation command is input, reservation registration for route setting is performed. As a result, it is possible to automatically open a route in which security is secured.

Further, it is preferable that the computer of the above-mentioned interlocking device has a track circuit information input means (42), a track circuit tracking means (27), and a route locking / unlocking means (28). In this case, the track circuit information input means (42) is for inputting track circuit information including the on-rail position information of the train output from the track circuit detection means, and the track circuit tracking means (27) is the track circuit information. Train position information input from the information input means (42) is input, the progress of the train is tracked based on the on-rail position information, and tracking information is output. ) Is input with the tracking information output from the track circuit tracking means (27), and when each track circuit section of the route in which the train is opened is advanced based on the track information, the track circuit for that track circuit section is entered. The reservation registered in the reservation table (12) shall be canceled. This makes it possible to automatically cancel the reservation for the route setting of the track circuit section, and to quickly set the route of another train while maintaining security.

Furthermore, in any of the interlocking devices of the present invention described above,
The computer preferably has a maintenance and replacement work management means (32). In this case, the maintenance replacement work management means (32) receives the setting command of the maintenance replacement work range as an input, refers to the track circuit reservation table (12) for the track circuit section specified by the command, and determines the track circuit. When the setting reservation of the route of another train for the section is not registered, the setting reservation is registered in the track circuit reservation table (12) for the track circuit section, and the maintenance replacement work range cancellation command is issued. Is input, and the setting reservation registered in the track circuit reservation table (12) for the track circuit section specified by the cancellation command is canceled. With this, it is possible to reliably exclude the entry of another train into the maintenance work range by a simple operation of setting and reserving the maintenance replacement work range for each track circuit section.

[Action]

With such a configuration, according to the present invention, the above object is achieved by the following actions.

That is, the present invention introduces the concept of track circuit reservation as a method of interlocking control, and directly determines the competition determination such as the track or work range required for the track setting request based on the presence / absence of track reservation set for each track circuit. The feature is that the track circuit reservation control is performed. The track circuit is provided for the control of rolling machines and traffic lights, or the operation of trains,
The line is divided into a plurality of sections suitable for performing such control, and a voltage is applied between a pair of rails in each section,
By detecting that the rails are short-circuited by the wheels of a train or the like, it is for detecting the entry of the train or the like into that section and the presence of the train, and is set over the entire range of the track. Therefore, if a route such as a train is set in a section of a certain track circuit, the logic of eliminating competition by not setting the routes of other trains in the section of that track circuit is extremely simple and clear. is there.

As described above, according to the present invention, the track circuit reservation control is performed in which the race circuit section included in the track according to the track setting request makes a competition determination based on whether or not a track setting reservation of another train or the like is registered. It is possible to make a judgment of competition, which is dangerous in the operation of trains, by a simple and clear interlocking control logic.

In addition, according to the track circuit reservation control, it is not limited to the route reservation for the operation of ordinary trains, etc., but also the reservation of the replacement work site, the maintenance work site, the emergency operation reservation, the reservation of the operation safety equipment use stop range. It is possible to commonly manage setting requests such as for each track circuit unit. Therefore, even if the work range for maintenance / replacement work is specified, the route of maintenance vehicles is set / opened, the range of replacement work, or the route for emergency operation is arbitrarily set or changed, all other trains Since you can judge the competitive relationship with
Not only will the range of linked control be expanded, but a highly flexible system will be possible. Note that those settings or changes can be realized without adding or changing special control logic, such as adding or changing a relay circuit or a spur file.

In addition, all races that are dangerous in train operation are concentrated in the track circuit reservation control, and the track wiring type at each station is replaced with the track circuit. In addition, the interlocking control logic can be standardized and generalized, and the line wiring type can be changed, the number of traffic signals can be increased, or the maintenance / replacement work can be changed easily.

In addition, the turning direction of the related rolling machine is specified by including it in the route setting request, and the rolling machine is switched in the designated turning direction of the rolling machine, and the route related to the route setting request is changed. It is possible to provide a roll control means (22, 23) for opening the. According to this, it is possible to easily open the route related to the route setting request based on the simple competition determination logic.

Further, a track circuit tracking means for fetching the on-rail information output from the track circuit and tracking the progress of the train, etc., and registering the on-rail information in the track circuit reservation table (2
7) and based on the tracking information output from the track circuit tracking means (27), the track circuit reservation table is reached when the train or the like reaches a predetermined point of the track related to the track setting request that has been opened. If a route locking / unlocking means (28) for canceling the route reservation of (12) is provided and the route reservation is automatically canceled and initialized, another route setting request can be met.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a functional system block diagram of an interlocking device according to an embodiment of the present invention. The interlocking device of the present embodiment is configured with a computer as a core, and includes various table groups in which data required for interlocking control is stored and various function groups for performing interlocking control. Various table groups are interlocking chart file 11, track circuit reservation table 12, turning machine reservation table 13, lever reservation table 14, course configuration table.
Includes 15 mag. The control function group includes a route reservation checking unit 21, a rolling control unit 22, a route locking unit 24, a signal control unit 25, a track circuit tracking unit 27, a route locking and unlocking unit 28, and hardware configured by a program. And a traffic signal control means 26. Further, the control function group includes a maintenance vehicle route creating means 31, a maintenance / replacement operation management means 32, and a maintenance vehicle tracking means 33 which are composed of a computer and are involved in maintenance / replacement work.

As the input information, according to the operation schedule from the host computer of the operation management system, the route information of the train transmitted in real time, or the route information 41 input from other terminals such as replacement work, and not shown. In addition to the track circuit information 42 output from the track circuit detecting means, the rolling lever information 43 and the replacement trouble information 44 respectively input through the input means.
There are maintenance work range information / usage stop range information 45, maintenance vehicle route information 46, and the like. In addition, from the interlocking device, a group of turning machines 50, a group of traffic lights 52 including a group of signs, and a group of route indicators.
Control output or display output is transmitted to 53 and the security facility 54, respectively.

In describing the details of this embodiment, an example of the track wiring in the station yard shown in the schematic view of FIG. The wiring type shown in the figure represents only a double-track down line, and a normal train progresses from N direction to S direction. This down line is 1 RAT down line and 1 down line by the turning machines 51 and 61.
It is branched to track number 1 RBT. As shown in the figure, the line is divided into a plurality of track circuits 51T, 1RAT, 1RBT, 61T and the like. This track circuit applies a voltage between a pair of rails in that section, and when a train or the like enters that section, it detects that the rails have been shortened by wheels, and This is to detect the on-rail. Further, the track circuit is originally a section for controlling a turning machine and a traffic signal, and is divided into sections suitable for performing such control. For example, where there is a rolling machine, one section is set across the rolling machine. Then, on the approach side of the track circuit 51T, an on-site traffic signal 1RA indicating the opening of the route on the down main line side and an on-site traffic signal 1RB indicating the opening of the route on the down line 1 side are installed. Further, a departure signal 5RE is installed on the exit side of the track circuit 1RAT of the down main line to indicate the opening of the route of the rolling machine 61. On the other hand, on the exit side of the track circuit 1RBT on the down line No. 1, a departure signal 6RE indicating the opening of the course of the rolling machine 61 is installed. Also, the rolling machine 51
Swap signs 51L, 52L, 21R, 22 at both ends of the track circuit including
R and 23L are installed. A range X surrounded by a chain line in the figure is an example of a replacement work range, and a range Y is an example of a maintenance work site (Nakaho-10).

First, the basic idea of the interlocking control in units of track sections, which is a feature of the present invention, will be described in the case where the train A opens a route to reach the down main line through the track circuit 51T. In this case, it is necessary that at least the track circuits 51T and 1RAT are not occupied by another vehicle B, such as during replacement work, or that the route of another vehicle or the like is not set. This condition is the track circuit of the route according to the route setting request of the train A.
It can be judged by checking whether the route setting of other trains is set on 51T and 1RAT or whether they are on the line. In addition, when a route is configured, the rolling machine must be locked, and the traffic signal and the replacement sign must be displayed in a predetermined display and locked so that no other train enters the route. I won't. The locking conditions of these route control devices can be easily set, managed, and controlled based on the route configuration based on the track circuit unit.

Here, the contents of each table will be described. The interlocking diagram file 11 stores predetermined interlocking control data such as types of routes to be configured, route control devices such as turning machines related to the route configuration, and locking conditions of these route control devices. To do. FIG. 3 shows an example of the interlocking chart. As shown in the figure, the interlocking control data is created based on the route to be set. The route is set with a route name and a route number with reference to a route control device such as a traffic signal or a replacement sign, and the starting point and the ending point data (the ending track circuit) of the route are entered in the route name column. . For example, in the case of a route in which train A starts from N direction and ends at track circuit 1RAT of the down main line,
Since the traffic signal relating to the route configuration is the on-site traffic signal 1RA, the description of the route name and the route number column is as shown in FIG. Corresponding to this route name column, a lock column, a signal control or check lock column, a route division lock column, an approach lock or a reserve lock column are provided.

In the lock column, enter the number of the rolling machine or the like that requires a lock when constructing the route along with the conversion position. In the case of the route number 1RA in the example of FIG. 2, it is specified that the turning machine 51 is changed to the orientation direction and locked. As for the conversion position, the side with diagonal lines in Fig. 2 is "localization",
The opposite side is "inversion", and in Fig. 3, the rolling machine number for locking in "inversion" is shown with an underline.
Also, in consideration of the case where the train etc. goes beyond the finish point,
When a turning machine within a certain range is lock-converted in a predetermined direction, the turning machine is set as an overrunning turning machine, and its number and the turning position are specified. In the example shown, the track circuit 61T is set as an overrunning protection zone in consideration of overrunning beyond the 1RAT of the landing point, and the rolling machine 61 is converted into an overrunning rolling machine and converted into a locking lock on the localization side. Stipulates that Furthermore, in the other lock column, a lock such as a directional lever, an open lever, and a check lever is specified.

The signal control or check lock column is a column that defines the control condition of the traffic light etc. of the route and the check lock condition, and is the inner side of the traffic light of the route (the traveling direction side than the traffic light etc.) The track circuit and the track circuit of the landing point are defined. In the case of signal control, for example, in the example of FIG. 3, when the train enters the first track circuit 51T, the traffic signal 1RA is “stopped (red)”, and the next track circuit 1RAT.
Hold that state until the train advances. Although not related to the above example, the check lock means locking a specific rolling machine when a train or the like is in a certain track circuit. If you are on the track circuit (51T) specified in the column of "Signal control or locking lock" in the row of the rolling machine in the chart, the rolling machine (51).
When the lock is locked at the specified position, the inner track circuit (51T) is advanced, and the landing track circuit (1RAT) is completed,
It is a condition for releasing the lock of the turning machine (51). In the signal control field, enter the track circuit on the way and the track circuit at the point of arrival. Although not specified in this embodiment, a general control column may be provided.

The route division locking column is provided with an intra-course locking column and an overrun protection section locking column. The route-classified lock means that the locks of the track circuit are sequentially and partly released as a train or the like enters or exits a track circuit indicated by a traffic signal or the like. For example, in the example of this embodiment, when the train A passes through the traffic light 1RA and leaves the track circuit 51T,
This means that the lock of 51T is released, that is, the reservation in the track circuit reservation table 12 is deleted. Therefore, when the train A moves out of the track circuit 51T, it also becomes a regulation to release the lock of the rolling machine. The same applies to the overrun protection zone lock.

The approach lock or hold lock column is a column that defines the conditions for executing the relocation when the relocation of the route (request for cancellation of the route) is requested. For example, if a train or the like has reached a track circuit that is close to the rolling machine on the required route, hold the locking machine of the rolling machine on that route and set the holding time of the locking machine. And wait for the train to stop completely before unlocking the lock and returning.

On the other hand, the track circuit reservation table 12 shows the reservation status of which track circuit is being used by the currently set or configured course or work range. For example, the fourth
As shown in the figure, this table 12 has a column corresponding to all the track circuits, and information such as the route or work number set or configured in the corresponding track circuit column is registered. Therefore, when a route setting or work range setting request is made, it is possible to easily make a conflict determination by checking whether or not a route or work number other than the route is registered in the corresponding field. . Although not shown, each track circuit is provided with a column for storing information as to whether or not a train or the like is present and identification information such as a train number. In the example of FIG. 2, track circuit 51T, 1RAT, 61 for route 1RA of train A
T is reserved. Therefore, even if the vehicle B in the replacement work tries to take the route S from the down track No. 1, the route 1RA of the train A is already reserved in the track circuit 61T, and therefore the route cannot be taken. Also, although not shown,
The track circuit reservation table 12 is provided with an on-rail information column registered and managed by the track circuit tracking means 27, and it is possible to confirm whether or not a train or the like is on the track circuit by the contents of this column. Has become. Although not shown, the track circuit reservation table 12 is provided with a track conflict check matrix, which is used for both the two tracks (1RA and 5RE), such as when there is a passing train. Allows duplicate reservations for one track circuit. As such an example, in addition to the passing train, there is a case where the maintenance work site and the use suspension information are duplicated to permit reservation registration in the same track circuit. The structure of the route conflict check matrix is such that types of route names, maintenance work names, track closures, etc. are arranged in a matrix, and the intersection column of them defines whether duplicate registration is allowed or not.

In addition, the turning machine reservation table 13 and the lever reservation table 14
Like the track circuit reservation table 12, is a table for registering this reservation as a turning machine according to the setting of a course or work. Here, the types of levers include a signal lever, a replacement indicator lever, a direction lever, an opening lever, and a check lever. Also,
The route configuration table 15 stores the conversion position data of the turning machine indicating the state of the route currently opened.

Next, the configuration of each storage means will be described together with the overall operation of this embodiment along the functional block diagram shown in FIG. 1 and the processing flowcharts of each means shown in FIGS. 5 to 10. When the route setting request is input by the route information 41, this processing is started. The route is set by designating the signal type, the starting point and the ending point corresponding to the contents of the route name column of the interlocking chart. This route setting request is input from a high-order computer terminal, a wireless terminal, a telephone connection terminal, or the like. The route information 46 of the maintenance vehicle is input to the maintenance vehicle route creation means 31 separately from the above route information 41. Also,
A route release request (route return position) for the set route or the opened route is input to the route lock releasing means 28 as necessary.

The route reservation checking means 21 inputs the route information (step 10
1), search the route information of the interlocking diagram file 11,
It is checked whether or not the route according to the input route setting request is defined in the route name column (step 10).
2). If not specified, a report to that effect is made and the processing ends (step 107). When specified,
By checking the lever reservation table 14, it is determined that the route for the setting request is not locked due to the lever etc., that is, the other direction has not reserved the lock in the opposite direction, or the use is stopped or the current stop is shown. It is confirmed (step 103).
If the use is stopped, a report to that effect is given and the process is terminated (step 107). If the use is not stopped, the track circuits that make up the track required by the request are extracted by searching the track information in the interlocking diagram file 11 (step 10).
Four). Next, check whether the extracted track circuit is not reserved for course by another train, etc.
The content of is searched and the route reservation is checked (step 105).
If there is another reservation, the fact is reported and the processing is terminated (step 107). If another train or the like has not been reserved, a route opening command is output to the rolling control means 22 (step 106).

As shown in FIG. 6, the turning control means 22 checks the on-rail information column of the track circuit reservation table 12 as to whether or not another train or the like is present on the track circuit of the route according to the route opening command. Yes (step 111). If the line is present, the fact is reported and the process ends (step 117). If the line is not present, the lock information including the relational switch defined in the lock column is retrieved and extracted from the interlocking chart file 11 (step 112). Next, it is determined by checking the rolling machine reservation table 13 whether or not the extracted rolling machine is under locking or the like due to other conditions, that is, whether it is not in use or is being handled alone (step 113). ). If the use is suspended, the fact is reported and the process is terminated (step 117). If the usage is not stopped, the conversion instruction of the related switching machine is output to the switching machine control means 23 (step 114). As a result, the rolling machine control means 23 outputs the rolling machine control output according to the command to the corresponding rolling machine of the rolling machine group 50. In addition, a rolling machine display signal indicating a conversion position output from the position detection provided on the rolling machine is fetched, and it is confirmed that the rolling machine control signal is operated. The turning machine display signal is input and registered in the route configuration table 15 as will be described later, so that the state of the route opening can be confirmed. In addition, the contents of the route configuration table 15 are displayed and output to a graphic device such as a CRT if necessary. On the other hand, the turning control means 22 searches the route configuration table 15 for confirmation and checks whether or not the requested route is configured (opened) (step 115). If the route is not configured, the fact is reported and the process ends (step 117). If the requested route is configured, a reservation command for the route is output to the route locking means 24 (step
116).

In response to this route reservation command, the route locking means 24 performs the processing shown in FIG. First, a related track circuit is extracted from the locking condition of the route according to the command read out from the interlocking chart table 11 and the information of the overrunning protection section (step 12).
1). With respect to the extracted track circuit, the track number and traffic signal type are registered in the track circuit reservation table 12 to reserve the track (step 122). According to the example of FIG. 2, the route 1RA is registered in the track circuits 51T, 1RAT, 61T as shown in FIG.
As a result, the path configuration of the opposite paths 51L, 52L, and 23L is substantially prohibited, and the replacement work and the maintenance work on the path of the path 1RA are substantially prohibited. in this way,
According to this embodiment, a race circuit reservation is used to determine competition,
Since competing routes are virtually eliminated, it is no longer necessary to specify the opposite route or the pure opposite route (same route) that should be mutually locked in the locking column of the interlocking diagram as in the past, and the interlocking diagram can be created. It will be easier. Also, the interlocking inspection is simplified.

After making such a track circuit reservation, based on the information in the interlocking diagram file 11, register the track number and cancellation condition in the lever reservation table 15 for a specific lever (open lever, check lever, direction lever). , Reserve the lever lock setting (step 123). Further, based on the lock information and the overtravel protection section information of the interlocking diagram file 11, the route number and the cancellation condition are registered in the rolling machine reservation table 15, and the rolling machine locking setting is reserved ( Step 124). Then, a signal control command is output to the signal control means 25 (step 125).

Upon receiving this signal control command, the signal control means 25 executes the processing shown in FIG. First, the relevant track circuit is extracted from the signal control or check lock column of the interlocking diagram file 11 (step 131). The track circuit reservation table 12 is searched to determine whether or not another train or the like is present in the extracted track circuit (step 132). Next, a command for outputting a traffic light or the like for opening the route to the actual display of "progress" is output (step 133). In the next step 134, a "stop" indication command is output to the traffic light control means 26 in accordance with the "stop" indication request input from the track circuit tracking means 27 described later by the progress / stop indication request (step 134). . The traffic light control means 26 switches the display of the corresponding traffic light or the like in response to an input traffic light, a sign or a progress / stop presenting request of the route indicator.

In this way, the basic processing for opening the route of one train or the like for normal train operation and replacement work is completed.

Here, the track circuit tracking executed in parallel with the series of processes will be described. The track circuit tracking means 27 takes in the inputted track circuit information 42 and rewrites the on-rail information of the track circuit reservation table 12 based on this. That is,
The track circuit information 42 is composed of drop information indicating that a train or the like has entered a certain track circuit and Koujo information indicating that the train or the like has entered from this track circuit. Etc. are tracked. In other words, when the drop information of a certain track circuit is input, the track circuit reservation table
When a train on the track is registered in the column of 12 corresponding track circuits, and the enhancement information of the track circuit is input, the registration is deleted. Therefore, by looking at the on-rail information column of the track circuit reservation table 12, the progress of the train can be tracked. This tracking information is output to the route locking / unlocking means 28. Note that when the train advances to an arrival / departure line without a track circuit, the registration of the on-rail train is deleted. In addition, a column for the station intermediate track circuit between the own station and the adjacent station will be provided, and when the train advances into the opening indicator light section of the adjacent station, the train in line will be in that column according to the advance information output from the interlocking device of the adjacent station To register.

As shown in FIG. 9, the route locking / unlocking means 28 is first activated by inputting the tracking information of the train or the like (step 141), and the route classification locking and the track circuit information in the name column of the interlocking diagram file 11 are set. Regarding the prescribed track circuit, the route reservation of the track circuit where the train or the like has advanced is deleted from the track circuit reservation table 12 in accordance with the on-rail position of the input tracking information of the train or the like (step 142). Then, in accordance with the cancellation of the track circuit reservation, the direction lever locks registered in the lever reservation table 14 are unlocked (step 143), and within the course registered in the rolling machine reservation table 13. And unlock the lock of the overrunning machine (steps 143, 144). As a result, it is possible to replace the premises replacement train B and to construct a course such as the opposite course 23L.

In this way, in response to the route setting request for normal trains and replacement work, the route of the request is opened by the track circuit control reservation, and at the same time, the track circuit reservation and rollover are performed as the train progresses. Release the lock on the path opening device such as a machine,
While maintaining security, it is possible to efficiently configure the route of the next train, etc.

On the other hand, since the wheels of the maintenance vehicle are insulated, the on-rail detection by the track circuit does not operate. Therefore, the track configuration of the maintenance vehicle has a different interlocking system from the above-mentioned ordinary train. That is, in addition to the above-mentioned respective means, maintenance vehicle route creating means 31, maintenance vehicle tracking means 33, maintenance
A replacement work management means 32 is provided.

The maintenance vehicle route creating means 31 is activated when the maintenance vehicle route information 46 is input, as shown in FIG. This information includes a maintenance vehicle route setting request and a cancellation request.
The maintenance vehicle route setting request is made by designating the traffic signal type, the starting point, and the ending point of the route of the maintenance vehicle (step 151).
When the route setting request is input, the maintenance vehicle route creating means 31 checks whether or not the route is registered in the interlocking diagram file 11 (step 152). If you are registered,
The route setting request is output to the route reservation checking means 21 (step 153). As a result, the route reservation checking means 21 is activated, and as in the case of the train described above, the processes shown in FIGS. 5 to 8 are executed and the route relating to the setting request is constructed. After that, the maintenance vehicle route creating means 31 uses the route configuration table 15
Is searched to confirm the conversion position of the related switching machine, and it is confirmed whether the requested route has been opened (step 154).
If it has been opened, an indication of the opening of the route is output to the computer terminal device or the like of the interlocking device (step 155), and the process ends. When the determination in step 152 is negative, the fact is reported in step 156 and the process is terminated.

The maintenance vehicle, as described above, by the start circuit information 42,
In-rail cannot be detected. Therefore, the maintenance vehicle tracking means 33
At the start of use of the maintenance vehicle, processing for generating the position of the maintenance vehicle is performed. In other words, in response to the route setting report of the maintenance vehicle, the track of the maintenance vehicle is assigned to the starting track circuit. On the other hand, the in-rail position of the maintenance vehicle is assigned to the landing track circuit in response to the route setting cancellation report of the maintenance vehicle. Then, according to the work completion report of the maintenance vehicle, the tracking information of the maintenance vehicle is erased, and the process ends.

The maintenance / replacement work management means 32 receives the replacement trouble information 44 and the maintenance work range information / use stop information 45, and closes the track.
When the maintenance vehicle use or maintenance work range setting is input, track circuits belonging to these work ranges are registered in the track circuit reservation table 12. Then, when the setting or cancellation of the work range is input, reservation registration or deletion of the registration is performed on the track circuit reservation table 12 for the track circuits within the range. On the other hand, when the replacement hindrance range, which is the replacement work range on the premises, is set or canceled, the reservation registration of the track circuit reservation table 12 or the deletion thereof is performed as described above. Although not shown, when the suspension of various equipment such as the security equipment 54 is set, the fact is registered in the turning machine reservation table 13 or the lever reservation table 14. Then, when the suspension of use is released, those registrations are deleted.

Other than that, although not clearly shown in the block diagram of FIG. The route return is the same as the route cancellation request, and like the route setting request,
It is performed by designating the information of the starting and ending track circuits. However, if the route is unlocked after returning to the normal position, follow the procedure below for security. First, when the route reversion is set, the presence or absence of a train or the like is checked with respect to the outer track circuit defined in the approaching or holding lock field of the interlocking chart file 11. When the train, etc. has already passed, only the course return is performed. On the other hand, when there is a line, the interlocking chart file 11
Or the passage unlocking process is performed after the elapse of the time defined in the holding lock column. When there is no line, the route reservation is canceled immediately.

〔The invention's effect〕

As described above, according to the present invention, there is an effect that the logic of competition determination can be simplified and clarified, and a new course and the like can be easily set.
