Abstract

PURPOSE:To realize, by a simple and clear interlocking control logic, the competitivity judgment which becomes dangerous to the running of, for example, a train, by directly judging the competitivity of a course or operation range covered by a course-setting request, on the basis of the presence or absence of a course reservation set in units of trajectory section. CONSTITUTION:This interlocking apparatus includes various tables 11 to 15 in which are stored data necessary for control of the interlocking operation, a course reservation by-reference examination means 21, a point control means 22, a source unavailability decision means 24, a signal control means 25, a travel-path trajectory pursuit means 27 and a course unavailability decision cancelling means 28, and a point control means 23. It is judged by search whether or not the cource covered by a course-setting request is prescribed as a course in the interlocking diagram file 11. When that course is prescribed, a trajectory section corresponding to this course is extracted and the trajectory section reservation table 12 is searched for to confirm the presence or absence of another previous corresponding reserve. When no reserve exists in regard to any trajectory section, an availability instruction concerning the course is outputted from the course reservation by-reference examination means 21 while an alteration instruction and a course reservation instruction as prescribed in a corresponding point are outputted from the point control means 23.

Description

[Detailed Description of the Invention] C. Industrial Application Field] The present invention is applicable to operation management of trains and vehicles (hereinafter collectively referred to as trains), management of train shunting operations, maintenance vehicles and maintenance work-related fields,
Or, it relates to a railway management system that manages emergency operation, etc. in an emergency, and specifically, it refers to a railway management system that manages emergency operation, etc. The present invention relates to an interlocking device that automatically switches traffic lights to open a desired route and displays the opening of the route on a traffic light.

[Prior art] In places where railroad tracks converge and diverge in a complex manner, such as inside a railway station, there are switches, signals, signs, etc. that are used to open the route and indicate whether or not it is possible to enter the route. There are many devices (hereinafter collectively referred to as route control devices) that display the following information, and these devices are switched according to the arrival, departure, passing, etc. of trains and maintenance vehicles (hereinafter collectively referred to as trains, etc.). ,
Routes requested by trains, etc. are opened.

The switching operations of these route control devices must be carried out promptly and appropriately in response to the arrival, departure, passage, etc. of trains, etc., so that the trains, etc. can operate and pass efficiently. Furthermore, there must be no mistakes in the operation of these route control devices, and if we relied solely on the operator's attentiveness to prevent such misoperation, as trains departed and arrived more frequently,
On the one hand, there is a risk of erroneous operation, and on the other hand, work efficiency is not improved.

Therefore, if a route control device is operated incorrectly, in order to eliminate the erroneous operation, ensure safety, and improve work efficiency, interlocks (chains) are established in advance for the operation relationships of multiple related route control devices. An interlocking device is used to set the lock (lock) and perform control operations accordingly.

In other words, the interlocking device first inputs data such as the starting point and destination of the train in accordance with the route setting request by the operator.
In response to this, the train checks whether the related route has already been set and opened by another train, and after confirming that it has not been set, the switch machine necessary to open the requested route is checked. It is designed to output a command to change the direction in a predetermined direction. Next, it is confirmed that the predetermined route has been opened based on the switching position signal output from the switch machine, and this is displayed on the display panel of the interlock device control panel. After setting a course in this way, it is necessary to disable the operation or work of other trains, etc. that block the course, and to secure the course until the train, etc. passes, by using related switch machines, etc. A lock order is issued to the police. Next, the track circuit detection means confirms that there are no other trains or vehicles on the route, switches the display of the relevant signal to the "proceeding (blue)" side and locks it, and the display panel to be displayed. After the train, etc. has passed through a predetermined point on the set route, the locks of the switch, etc. are released.

In this way, the operator can simply input data such as the departure and arrival points of trains, etc., and the route will be automatically opened without conflict, and the necessary displays will be displayed, which will not only prevent erroneous operations, but also , the frequent arrival and departure of trains can be handled efficiently.

As interlocking devices having such a function, there are conventionally known relay-type interlocking devices in which the interlocking control logic is constituted by a relay circuit, and electronic interlocking devices using a microcomputer. The former type of relay-type interlocking device locks the switch and traffic lights within the controlled range, and between the traffic lights, taking into account all possible combinations. The basic idea is to prevent it. In addition, route setting is performed using a departure lever, a destination push button, or a signal lever, and route conflicts with trains, etc. during the opening operation are eliminated by a route selection circuit or a lever relay circuit assembled with a relay circuit, and related transfers are performed. Indirect competitive judgment methods are used, such as locking the lever or eliminating the enemy via a switch with a route locking mechanism.

[Problems that sales are trying to solve] However, since relay-type interlocking devices assemble interlocking controls such as locks using hardware relay logic circuits, the interlocking control logic is fixed and difficult to change. Therefore, the following problems arise.

In other words, since the interlocking control logic is composed of relay circuits, there is no need to change the line wiring type, add signals, or perform maintenance.
There is a problem in that it is not possible to respond flexibly to changes in the format of replacement work. For example, when specifying the work area for maintenance/shunting work, setting/opening routes for maintenance vehicles, or shunting work, two routes coming from opposite directions (pure Because the relay circuit is assembled based on the concept of mutual locking so that opposing routes (opposing routes), etc. are not set at the same time, the route and work range designation for maintenance and replacement work are fixed. Moreover, in order to implement these changes, relay logic circuits must be added or changed, which requires a great deal of effort and expense for on-site wiring work and function confirmation tests.

On the other hand, the latter electronic interlocking device realizes the relay logic circuit of the above-mentioned relay system using a spur file mechanism configured with software logic, and the interlocking control method is basically the same.

In other words, the basic idea is to consider all possible combinations of locks between switch machines, traffic lights, and between traffic lights within the control target range, thereby covering dangerous erroneous operations and preventing malfunctions. This is an information file that associates track circuits with each other in conjunction with the opening direction of the switch. Then, when starting point/destination information is input, a search is made to see if there is a route in the spur file that leads to the destination specified by the destination information using the starting point information as a key, and the route in the spur file is searched. Perform connection processing.

When the specified route cannot be connected, or when another route has been set, it is assumed that the requested route does not exist, and a report indicating that the route cannot be configured is made. When the route can be connected, next, the opening direction (turnover position) of the relevant switch machine is determined based on the route.
Information is extracted from the connection status of the spur file to control switching of the switch machine. As a result, after all related point machines have been successfully converted, the unit usage information of point machines, track circuits, etc. is registered in the spur file. In addition, the route locking table is also locked for each route division. However, since the control logic of this spur file is made up of a complicated mesh file, relay-type As in the case above, there are problems that cannot be easily addressed. In other words, as mentioned above, the contents of the work scope specification, route setting and opening of maintenance vehicles, and shunting work for maintenance and replacement work are fixed, and in order to realize these changes, it is necessary to Since additions and changes are required, there is a problem in that a great deal of effort and money is spent on data creation work and function confirmation tests.

In addition to the flexibility to change the interlocking control conditions mentioned above,
According to conventional interlocking devices, the interlocking control logic must be configured individually according to the track wiring shape in the station premises to which it is applied, so the control logic is greatly influenced by the unique wiring shape of each station. There is a problem in that standardization of control logic and subsequent modification are difficult.

In addition, in conventional route setting, the departure point and destination were treated separately, so the operator's intentions were unknown until the destination information was input after the departure point information was received, and there were multiple If two operators compete with each other to operate the route, there is a risk that a combination of start and end points that differs from the requested route may occur. Conventionally, the route selection circuit described above functions to eliminate such incorrect route settings, but its processing logic is complex and requires a unique configuration for each station, making it difficult to create a spur file. Moreover, there is the problem that functional testing requires a lot of effort.

In addition, because locks must be taken into consideration for all combinations of switches, traffic lights, and between traffic lights within the controlled range, the contents of the interlock diagram that defines the interlock control conditions become complicated. Not only is it complicated to create, but it is also difficult to decipher, so there is a problem that it cannot be loaded directly into a computer as a data file.

An object of the present invention is to solve the above-mentioned conventional problems.In other words, it is possible to simplify and clarify the competition judgment logic, standardize and simplify the configuration of interlock control logic, and easily create interlock charts that can be directly applied to a computer. The purpose is to provide an interlocking device that can be loaded.

[Means to solve the problem]

In order to achieve the above object, the interlocking device of the present invention divides the trajectory of the interlocking control target range into a plurality of sections, and includes a track section reservation table in which course setting reservations are registered for each track section, and an interlocking control object. multiple routes by traffic light type and starting point/
Interlocking that is defined by destination information and that defines interlocking control conditions for route control equipment such as switch machines, which are necessary for configuring the route corresponding to each route, based on the classification of the track section. The chart file and the route setting request, the type of signal, etc., the starting point of the train, etc.
A route setting request input means for specifying and inputting destination information; and a route setting request input means for inputting destination information; and a route setting request input means for searching whether or not the route that deviates from the route setting request inputted from this means is defined in the route of the linked chart file; If so, extract the track section related to the route in question, search the track section reservation table for the extracted track section to check whether there are other reservations, and if there are no reservations for all the track sections. , route reservation checking means for outputting a command to open the route; and, based on the route opening command output from this means, searching the interlocking diagram file and specifying the relevant switch and switching position for route locking. and after outputting a prescribed conversion command to each corresponding switch machine, a switch control means outputs a route reservation command, and based on the route reservation command output from this means, The present invention is characterized by comprising a route locking means for registering reservations for all related track sections of the requested route in the track section reservation table.

[Function] With this configuration, according to the present invention, the above object is achieved by the following function.

In other words, the present invention introduces the concept of track section reservation as an interlocking control method, and makes conflict judgments regarding courses, work ranges, etc. related to course setting requests directly based on the presence or absence of course reservations set for each track section. Since the track section reservation control is implemented, conflict judgments that can be dangerous in the operation of trains, etc. can be realized using simple and clear interlocking control logic.

In addition, in conjunction with the above-mentioned track section reservation control method, the interlocking diagram file defines multiple routes subject to interlocking control by signal type and departure and destination information, and configures the route in correspondence with each of the routes. Interlock control conditions for route control equipment such as switch machines, which are necessary for this purpose, can be defined based on the classification of the track sections. As a result, all the conditions necessary for interlock control can be defined in correspondence with the course, making creation easier. Moreover, the logic of other interlocking control means such as the course reservation checking means can be the same, by simply creating interlocking diagrams according to the track wiring type and interlocking conditions of each station. The circuit, the route control equipment such as a switch, and their control conditions can be read out from the interlocking chart and the control can be executed according to those conditions, so the interlocking devices can be standardized and simplified. Ru. This will also simplify interlocking tests to confirm functionality.

In addition, according to track section reservation control, reservations are not limited to route reservations for normal train operations, but also reservations for shunting work sites, reservations for maintenance work sites, reservations for emergency operations, and reservations for the range of suspension of operation security equipment. Setting requests such as the following can be commonly managed for each track section. Therefore, even if you arbitrarily set or change the work range specification for maintenance/shunting work, the route setting/opening of maintenance vehicles, the shunting work range, or the emergency driving route,
Since it is possible to judge the competitive relationship with all other trains, etc., not only the scope of interlocking control targets is expanded, but also a highly flexible system becomes possible. Please note that these settings or changes are
This can be achieved without adding or changing special control logic, such as adding or changing relay circuits or spur files.

Moreover, all of the dangerous conflicts in the operation of trains, etc. are consolidated into track section reservation control, and the track wiring type at each station is replaced with a track section, so it is affected by differences in track wiring types and interlocking conditions. It is possible to standardize and generalize the interlocking control logic without any problems, and it is also possible to easily respond to changes in the line wiring type, addition of traffic lights, or changes in the form of maintenance/replacement work. - [Example] Hereinafter, an example of the present invention will be described 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 this embodiment is configured with a computer as its core, and includes various table groups in which data necessary for interlocking control is stored, and various functional groups for executing interlocking control. The various table groups include an interlocking diagram file 11, a track circuit reservation table 12, a switch machine reservation table 13, a lever reservation table 14, a route configuration table 15, and the like. The control function group includes a route reservation checking means 21, a point control means 22, a route locking means 24, a signal control means 25, a track circuit tracking means 27, a route locking and unlocking means 28, and hardware. It includes a point control means 23 and a traffic light control means 26, which are constituted by the following. In addition, the control function group includes:
It includes a maintenance vehicle route creation means 31, a maintenance/replacement work management means 32, and a maintenance vehicle tracking means 33, which are configured by a computer and are used for maintenance/replacement work.

Input information includes train route information transmitted in real time according to the train schedule from the host computer of the operation management system, or route information 41 input from other terminals such as for shunting work, and route information 41 (not shown). In addition to the track circuit information 42 output from the track circuit detection means, the following information is input through the respective input means: rolling and lever information 43, replacement failure information 44, and maintenance work range information/suspension range information 45.
and maintenance vehicle route information 46. In addition, from the interlocking device, a switch equipment 51 and a group of traffic lights, etc. 52 including a group of signs, etc.
The control output or display output is transmitted to the route indicator group 53 and the safety equipment 54, respectively.

Hereinafter, in explaining the details of this embodiment, the explanation will be made with appropriate reference to an example of track wiring in a station premises, which is schematically shown in FIG. 2. The illustrated wiring type represents only a double-track down line, and trains normally travel from the N direction to the S direction. This down line is connected to the down main line I RAT by switch machines 51 and 61.
and down] The line is branched into IR and BT. As shown in the diagram, the track includes a plurality of track circuits 51T, IRAT, and IRB.
It is classified into T, 61T, etc. This track circuit applies voltage between a pair of rails in that section, and when a train, etc. enters that section, it detects that the gap between the rails is shortened by the wheels, and the train, etc. It detects the presence of railway lines. Additionally, the track circuit is originally a section for controlling switches and traffic lights, and is divided into sections suitable for such control.

For example, in a place where there is a point machine, one section is set across the point machine. And track circuit 51T
On the approach side of
RA and on-site signal IR indicating the opening of the route on the 1st outbound track
B is installed. In addition, the down main line track circuit IRA
A departure signal 5RE is installed on the exit side of T to indicate the opening of the route for the switch 61. On the other hand, track circuit I of downbound track No. 1
A departure signal 6RE is installed on the exit side of the RBT to indicate the opening of the route for the switch 61. In addition, there are shunting signs 51L at both ends of the track circuit including switch machines 51 and 61.

52L, 21R, 22R, and 23L are installed.

In addition, the range X surrounded by the dotted chain line in the figure is an example of the replacement work range, and similarly the range Y is the maintenance work site (Nakaho-10
) is an example.

First, the basic concept of interlocking control in units of track sections, which is a feature of the present invention, will be explained for the case where a route is opened for train A to arrive at the downhill main line through track circuit 51T. In this case, at least the track circuit 51T and LRAT
The condition is that there is no other vehicle B on the line that is undergoing shunting work, or that no route has been set for other vehicles. This condition can be determined by checking whether the route of another train is set on the track circuit 51T and IRAT of the route requested by train A, or whether the train is on the track. In addition, when a route has been constructed, switch machines must be locked, traffic lights and switching signs must be displayed in the designated manner, and the route must be kept locked to prevent other trains from entering the route. No. The locking conditions for these route control devices can also be easily set, managed, and controlled based on the route configuration based on each track circuit.

Here, the contents of each table will be explained. The interlocking diagram file 11 stores predetermined interlocking control data such as the types of routes to be constructed, route control devices such as switch machines related to the route configuration, and locking conditions for these route control devices. It is something to do. Figure 3 shows an example of an interlocking chart. As shown in the figure, the interlock control data is created based on the set course. The route name and route number are set based on route control devices such as traffic lights and switching signs, and the route's starting point and destination data (destination track circuit) are entered in the route name column. . For example, if train A starts from the N direction and ends at the track circuit IRAT on the down main line, the signal for the route configuration is the in-house signal IRA, so the entries in the route name and route number columns are , the contents are shown in Figure 3. Corresponding to this course name field, the lock field,
A signal control or check lock field, a route division lock field, and an approach lock or hold lock field are provided.

In the lock column, enter the number of the switch machine, etc. that needs to be locked when configuring the route in question, along with its switching position. In the example in Figure 2, if the route number is IRA, switch machine 51
It stipulates that the camera should be locked by changing the direction of orientation.

In addition, the switching position is the diagonally shaded side in Figure 2.
, the opposite side is the "reverse position", and in Fig. 3, the switch machine number that is locked in the "reverse position" is underlined.

Also, in consideration of the case where the train etc. progresses beyond the destination,
When switching and locking a switch within a certain range in a predetermined direction, the switch is set as an overrunning switch and its number and switching position are specified.

In the illustrated example, the track circuit 61T is set as an overrun protection section in consideration of the case where the train overruns beyond the destination point I RAT.
It is specified that the switch 61 is converted to the normal position side and locked as an overrunning switch. Furthermore, in the other lock columns, second-class locks are specified for direction levers, opening levers, and verification.

Signal control or traffic lock is a field that specifies the control conditions for traffic lights, etc. on the route, and the traffic lock conditions, and is located inside the traffic lights, etc. on the route (on the side in the direction of travel from the traffic lights, etc.). A track circuit and a destination track circuit are defined. In the case of signal control, for example in the example of FIG. 3, the first track circuit 51. When the train enters the track T, set the signal 1RA to "Stop (red) J" and maintain that state until the train advances to the next track circuit IRAT. Also, switch the display of the signal IRA etc. to "Proceed (green)". The information in this column is also used as a track circuit that should be checked to ensure that there are no trains or the like on the line. Also,
Although not relevant to the example above, a switch lock refers to locking a specific switch when a train, etc. is on a certain track circuit. When the line is on the track circuit (5IT) specified in the column of "Signal control or locking" in the row of the switch machine, the switch machine (
51) in a specified position, and lock this inner track circuit (51) in a specified position.
T) and completes entering the destination track circuit (], RAT), this becomes a condition for unlocking the switch machine (51). In addition, the route circuit and the destination track circuit are written in the signal control tank.

Although not specified in this embodiment, a general control tank may be provided.

The route section lock column includes a route section lock column and an overrun protection section lock column. Sectional locking refers to sequentially releasing the locking of a track circuit as a train, etc. enters a certain track circuit based on an indication from a signal, etc., and then advances from the track circuit. For example, in the example of this embodiment, when train A passes through signal IRA and advances to track circuit 51T, it is stipulated that the lock of 51T is released, that is, the reservation in track circuit reservation table 12 is deleted. It turns out. Therefore, once train A advances through the track circuit 51T, the switch is unlocked. The same applies to overrunning protection zone locking.

The approach lock or hold lock column is a column that defines the conditions for executing the reinstatement when the reinstatement of the course (course cancellation request) is requested. For example, if a train, etc. has reached a track circuit close to a switch on its requested route, the switch on that route is kept locked and the lock hold time is set. Then, wait for the train to come to a complete stop before unlocking it and returning to the station.

On the other hand, the track circuit reservation table 12 shows the reservation status of which track circuit is used by the currently set or configured course or work range. For example, as shown in FIG. 4, this table 12 has columns corresponding to all track circuits, and information such as the number of the route or work set or configured is stored in the column of the corresponding track circuit. be registered.

Therefore, when a request is made to set a course or scope of work, it is easy to judge competition by checking whether or not other courses or work numbers are registered in the corresponding column. . Further, although not shown, a column is provided for storing information on whether a train or the like is present on each track circuit and identification information such as a train number. In the example in Figure 2, regarding the route IRA of train A, track circuit 51T, IR
AT and 61T are reserved. Therefore, even if vehicle B, which is undergoing shunting work, attempts to take the route in the S direction from downbound platform 1, it cannot take that shunting route because the route IRA of train A is already reserved on the track circuit 61T. Although not shown, the track circuit reservation table 12 is provided with a track location information field that is registered and managed by the track circuit tracking means 27, and the contents of this field indicate whether a train or the like is located on that track circuit. You can check whether there are any. Although not shown, the track circuit reservation table 1
2, a route conflict check matrix is provided, which allows duplicate reservations for one track circuit by both routes (IRA and 5RE), such as when there is a passing train. I'll do what I do. Examples of this include cases in which, in addition to passing trains, reservations are allowed to be registered on the same track circuit because the maintenance work site and out-of-use information overlap. The configuration of the route conflict check matrix is such that types such as route names, maintenance work names, and track closures are arranged in a matrix, and the intersection column specifies whether or not duplicate registration is allowed.

In addition, point machine reservation table 13 and point machine reservation table 1
Similarly to the track circuit reservation table 12, 4 is a table in which reservations for switch machines and levers associated with course or work settings are registered. Here, types of levers include signal levers, shunting sign levers, direction levers, opening levers, inspection levers, and the like. Further, the route configuration table 15 stores switching position data of switch machines indicating the status of the currently opened route.

Next, the configuration of each functional means will be explained along with the overall operation of this embodiment along with the functional block diagram shown in FIG. 1 and the processing flowcharts of each means shown in FIGS. 5 to 10. When a route setting request is input based on the route information 41, this process is started. The route is set by specifying the signal type, starting point, and ending point that correspond to the contents of the route name column of the interlocking chart. This route setting request is input from a higher-level computer terminal, wireless terminal, telephone connection terminal, or the like. The maintenance vehicle route information 46 is input to the maintenance vehicle route creation means 31 separately from the route information 41 described above. Further, if necessary, a route release request (route reinstatement) for the set route or the opened route is sent to the route lock release means 2.
8 is input.

The course reservation checking means 21 inputs the course information (step 101), searches the interlocking diagram file 11 for course information, and checks whether the course corresponding to the input course setting request is specified in the course name column. is checked (step 102). If it is not stipulated, a report to that effect is made and the process ends (step 107). When specified, the lever reservation table I4 is checked to see if the route for which the setting request is being made is not locked by a lever, that is, if there is no other route reserved for locking in the opposite direction, or if the route is not being used. It is checked whether the display is stopped or the display is not stopped (step 103). If the use is suspended, etc., a report to that effect is made and the process is terminated (step 107). If the track circuit is not out of use, the track circuit constituting the requested route is extracted by searching for route information in the interlocking diagram file 11 (step 104). Next, the contents of the track circuit reservation table 12 are searched to check whether the route reservation for this extracted track circuit has been reserved by another train, etc. (
Step 105). If there are other reservations, that fact is reported and the process ends (step 107). If no other train has been reserved, a route opening command is output to the rolling control means 22 (step 106).

As shown in FIG. 6, the point control means 22 checks the track presence information column of the track circuit reservation table 12 to see if any other trains are present on the track circuit of the route specified by the route opening command. (Step 11J). If the line is on the line, that fact is reported and the process ends (step 117). If the line is not on the line, lock information including the related switch machine specified in the lock column is searched and extracted from the interlock chart file 11 (step 112). Next, check whether the extracted switch machine is not locked due to other conditions, that is, whether it is not in use, is not being used alone, or is not locked due to reservations for other routes. The decision is made by checking the switch machine reservation table 13 (step 113). If the device is out of use, etc., this fact is reported and the process ends (step 117). If the switch machines are not in use, a conversion command for the related switch machines is output to the switch machine control means 23 (step 114). As a result, the point machine control means 2
3 outputs a switch control output to the corresponding switch of the switch equipment 51 in accordance with the command. In addition, the switch machine display signal representing the switching position outputted from the position inspection equipment provided on the switch machine is taken in, and it is confirmed that the switch machine operates according to the switch machine control signal. Note that the switch display signal is input and registered in the route configuration table 15, as will be described later, so that the state of route opening can be confirmed.

Further, the contents of the route configuration table 15 are displayed on a graphic device such as a CRT, if necessary. on the other hand,
The point control means 22 uses the route configuration table 1 for confirmation.
5 to check whether the requested route has been constructed (opened) (step 115). If the route has not been configured, that fact is reported and the process ends (step 117).

If the requested route has been configured, a reservation command for that 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 process shown in FIG. 7. First, related track circuits are extracted from the route locking conditions and overrunning protection zone information related to the command read from the interlocking chart table 11 (step 121).
). Regarding the extracted track circuit, the route number and signal type are registered in the track circuit reservation table 12, and the route is reserved (step 122). According to the example in FIG. 2, as shown in FIG. 4, the track circuits 5 IT, 1. The course IRA is registered in RAT, 61T. As a result, oncoming paths 51L and 5
The route configurations of 2L and 23L are substantially prohibited, and replacement work and maintenance work on the route of route IRA is also substantially prohibited.

In this way, according to this embodiment, conflicts are determined based on track circuit reservations, and conflicting routes are substantially eliminated.
It is no longer necessary to specify opposing routes that should be mutually locked or pure opposing routes (same route) in the lock column of the interlocking chart, as in the past, and the creation of the interlocking chart becomes easier. Further, the linked inspection is also simplified.

After making such a track circuit reservation, the course number and cancellation conditions are registered in the lever reservation table 15 for a specific lever (opening lever, inspection lever, direction lever) based on the information in the interlocking chart file 11. , and makes a reservation for lever lock setting (step 123). Also, based on the locking information and overrunning protection zone information in the interlocking diagram file 11, the route number and release conditions are registered in the switch machine reservation table 15, and the switch machine lock setting is reserved ( Step 124).

Then, a signal control command is output to the signal control means 25 (
Step 125).

In response to this signal control command, the signal control means 25
Execute the process shown in the figure. First, linked chart file 11
The related track circuit is extracted from the signal control or check lock column (step 131). The track circuit reservation table 12 is searched to determine whether or not other trains are on the extracted track circuit (step 132). Next, a command is output to display the traffic lights and the like related to the opening of the route to indicate "progress" (step 133). Next step 134
Then, in accordance with the "stop" display request input from the track circuit tracking means 27, which will be described later, as a progress/stop display request, "
A "stop" display command is output to the traffic light control means 26 (step 134). The traffic light control means 26 switches the display of the corresponding traffic light, etc. in response to the input request for displaying progress/stop of the traffic light, sign, or route indicator.

In this way, the basic processing involved in opening a route for one train, such as normal train operation and shunting work, is completed.

Here, track circuit tracking that is executed in parallel with the series of processes described above will be explained. The track circuit tracking means 27 takes in the input track circuit information 42 and rewrites the line location information in the track circuit reservation table 12 based on this. That is, the track circuit information 42 is based on fall information indicating that a train, etc. has entered a certain track circuit, lifting information indicating that a train, etc. has advanced from that track circuit, and the track circuit number. Based on this, trains, etc. are tracked. In other words, when falling information for a certain track circuit is input, a train on the line is registered in the column of the corresponding track circuit in the track circuit reservation table 12, and when lifting information for that track circuit is input, Delete registration. therefore,
By looking at the track location 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 lock/unlock means 28. Furthermore, when proceeding to an arrival or departure line without a track circuit, the registration of the train on the line is deleted. In addition, a column for the station intermediate track circuit between station 0 and the adjacent station is provided, and when a train advances through the opening indicator light section of the adjacent station, the advance information output from the interlocking device of the adjacent station is displayed in that column. Register.

As shown in FIG. 9, the route lock/unlock means 28 firstly
Step 141)
, the course reservations for the track circuits into which the train has advanced are sequentially deleted from the track circuit reservation table 12 according to the track circuit of the input track circuit number and the track position in the tracking information (step 142).

Then, in accordance with the cancellation of the track circuit reservation, the lock of the direction lever registered in the lever reservation table 14 is released (step 143), and the lock of the direction lever registered in the point machine reservation table 13 is released. The @ lock of the overrunning point machine is unlocked (steps 143 and 144). This results in
This makes it possible to perform shunting work for the internal shunting train B, and also to configure the route such as the oncoming route 23L.

In this way, in response to route setting requests for normal trains and shunting work, the requested route is opened by track circuit control reservations, and track circuit reservations and switching are made in accordance with the progress of trains, etc. Unlock the route clearing equipment of aircraft etc.
To efficiently configure the route of the next train, etc. while maintaining security.

On the other hand, since the wheels of maintenance vehicles are insulated, track presence detection using track circuits does not work, and therefore the route configuration of maintenance vehicles has an interlocking system that is different from that of the above-mentioned normal trains. That is, apart from each of the above-mentioned means, a maintenance vehicle route creation means 31, a maintenance vehicle tracking means 33, and a maintenance/replacement work management means 32 are provided.

The maintenance vehicle route creation means 31, as shown in FIG.
It is activated when maintenance vehicle route information 46 is input. This information includes a maintenance vehicle route setting request and a cancellation request. A maintenance vehicle route setting request is made by specifying the signal type and starting and ending points for the maintenance vehicle's route (step 1).
51). When a route setting request is input, the maintenance vehicle route creation means 31 checks whether the route concerned is registered in the interlocking chart file 11 (step 152).

If 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 the processes shown in FIGS. 5 to 8 are executed as in the case of the train described above, and the route according to the setting request is configured.

After that, the maintenance vehicle route creation means 31 searches the route configuration table 15 to confirm the switching position of the related switch machine,
Check whether the requested route has been opened (Step 1)
54). If the route has been opened, a route opening display is output to the computer terminal device, etc. of the interlocking device (step 155).
), the process ends. Incidentally, if the judgment in step 152 is negative, a report to that effect is made in step 156 and the process ends.

The maintenance vehicle cannot detect the presence of the track based on the track circuit information 42 as described above. Therefore, maintenance vehicle tracking means 33
performs processing to generate the location of the maintenance vehicle at the start of use of the maintenance vehicle. In other words, in response to the route setting report of the maintenance vehicle,
The location of the maintenance vehicle is assigned to the track circuit at that starting point. On the other hand, in response to the maintenance vehicle's route setting cancellation report, the maintenance vehicle's location is assigned to the destination track circuit. Then, in response to the report that the work of the maintenance vehicle has been completed, the tracking information of the maintenance vehicle is deleted and the process is terminated.

The maintenance/replacement work management means 32 includes replacement failure information 44,
When the maintenance work range information/suspension information 45 is input and there is a setting input for track closure, maintenance vehicle use, or maintenance work range, track circuits belonging to those work ranges are registered in the track circuit reservation table 12. do. When the setting or cancellation of the work range is input, the track circuit within the range is registered in the track circuit reservation table 12 or the registration is deleted. On the other hand, when the shunting hindrance range, which is the shunting work range within the premises, is set or canceled, the reservation is registered or deleted in the track circuit reservation table 12 in the same manner as described above. In addition, although not shown, when the suspension of use of various equipment such as the security equipment 54 is set, that fact is registered in the switch reservation table 13 or the switch reservation table 14. Then, when the suspension of use is lifted, those registrations are deleted.

In addition, although not clearly shown in the block diagram of FIG. 1, course return will be explained. A course reversal is the same as a course cancellation request, and like a course setting request, it depends on the signal type,
This is done by specifying the information on the starting and ending track circuits. However, if the route is to be unlocked by restoring the route, please follow the steps below for safety reasons. First, when course reversal is set, the outer track circuit specified in the approach or hold lock column of the interlocking diagram file 11 is checked to see if there are trains or the like on the line. Then, when a train or the like has already passed, only the course is restored. On the other hand, when there is a line, the linked chart file 11
The route will be unlocked after the time specified in the approach or hold lock field has elapsed.

In addition, if there is no line, the route reservation is canceled immediately.

[Effects of the Invention] As explained above, the present invention has the following effects.

That is, the present invention introduces the concept of track section reservation as an interlocking control method, and directly performs conflict judgments on courses and work ranges related to course setting requests based on the presence or absence of course reservations set for each track section. Since track section reservation control has been adopted, conflict judgments that can be dangerous in the operation of trains, etc. are avoided.
This can be realized using simple and clear interlocking control logic.

In addition, in conjunction with the above-mentioned track section reservation control method, the interlocking diagram file defines multiple routes subject to interlocking control by signal type and departure and destination information, and configures the route in correspondence with each of the routes. Interlock control conditions for route control equipment such as switch machines, which are necessary for this purpose, can be defined based on the classification of the track sections. As a result, all the conditions necessary for interlock control can be defined in correspondence with the course, making creation easier. Furthermore, by simply creating an interlocking diagram according to the track wiring type and interlocking conditions of each station, the logic of other interlocking control means such as the course reservation checking means can be the same. The circuit, the route control equipment such as a switch, and their control conditions can be read out from the interlocking chart and the control can be executed according to those conditions, so the interlocking devices can be standardized and simplified. Ru. This will also simplify interlocking tests to confirm functionality.

In addition, according to track section reservation control, it is possible not only to reserve routes for normal train operations, but also to request settings such as reservations for shunting work sites, reservations for maintenance work sites, and reservations for areas where operation safety equipment is suspended. , can be commonly managed on a track section basis. Therefore, even if you arbitrarily set or change the scope of work for maintenance and shunting work, the setting and opening of routes for maintenance vehicles, or the range of shunting work, there will be competition with all other trains, etc. This not only expands the scope of operations subject to interlock control, but also enables a highly flexible system.

Note that these settings or changes can be realized without adding or changing special control logic, such as adding or changing a relay circuit or spur file.

Moreover, all of the dangerous conflicts in the operation of trains, etc. are consolidated into track section reservation control, and the track wiring type at each station is replaced with a track section, so it is affected by differences in track wiring types and interlocking conditions. It is possible to standardize and generalize the interlocking control logic without any problems, and it is also possible to easily respond to changes in the line wiring type, addition of traffic lights, or changes in the form of maintenance/replacement work.

Furthermore, since conflicts are judged on a track section basis, conflict judgment logic and locking logic for switches, traffic lights, etc. are simplified, making it easier to create interlocking diagrams that are the basis of interlocking control. Furthermore, it becomes unnecessary to check whether routes that should be mutually locked are excluded, and the interlocking inspection can be simplified.
