Description

  The present invention relates to a relay circuit connection network data generation device, a relay circuit connection network data generation method, and a program thereof, in which an interlocking device that controls a switch and a traffic light generates relay circuit connection network data used for the control. .

 The interlocking device controls the operation of the switch and traffic light on the railway, locks the switch so that it does not switch while the train is moving, and interferes with the route on which the train is moving. This is a security device that provides a certain chain relationship between the operation of the switch and the traffic light so that no other route is formed. That is, the interlocking device has basic functions of general control and lock. General control is to control the switch of the switch when handling the lever of the traffic light. In addition, the lock means that the progress cannot be shown on the traffic signal unless the switch is changed in a predetermined direction. In an actual station premises, there are many traffic lights and switchboards, and their interrelationships are intricately intertwined.

  Here, since the operation of such an interlocking device varies greatly from station to station, an “interlocking chart” is created to clarify the control logic unique to the station. The interlocking chart consists of a "wiring schematic" that plots the line alignment and signal equipment installation status, and an "interlocking chart" that describes the control conditions of the interlocking device in a table. These wiring schematic diagrams and interlocking tables are described in lines and symbols in a compact manner so that the movement of the train and the state of signal equipment can be easily seen and understood by humans. In order to operate as an interlocking device, technology for realizing control is required. As an implementation form, a method of creating a program that shares the interlocking operation by a computer and inputting an interlocking table as data, and sequence control There is a way.

Sequence control is to construct logic based on a series circuit or parallel circuit based on the simple principle of driving an electromagnet called a relay by a switch called a contact point, but recently, a Boolean value AND, OR using a computer. , Are often realized by NOT-based logic sequences. This control method has a merit that the internal operation can be clearly grasped because the logic is simple, but it is necessary to create a logic circuit or a logical expression for each station, which requires a lot of labor.

Hereinafter, a relay circuit connection network data generation device according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing an example of a schematic wiring diagram.
FIG. 2 is a diagram showing an interlocking table.
The interlocking chart is composed of a “wiring schematic diagram” as shown in FIG. 1 that plots the line alignment and the installation state of the signal equipment, and a “interlocking chart” as shown in FIG. 2 that describes the control conditions of the interlocking device.
The relay circuit connection network data generating device in the present embodiment inputs interlocking diagram data composed of these wiring schematic diagrams and interlocking tables, and generates relay circuit connection network data based on the interlocking diagram data.

First, an outline of processing of the relay circuit connection network data generation device will be described.
<Structure of connection diagram>
In order to automatically generate the relay circuit connection network data by the computer of the relay circuit connection network data generation device, it is important to structure the concept. The object of structuring requires the structuring of the elements constituting the relay circuit connection network data and the structuring of the standard connection diagram from which the relay circuit connection network data is based.
The elements that make up the relay circuit connection network data (relay circuit constituent elements) are levers, landing buttons, track circuits, relays, etc., and these attributes, functions, and correlations are reproduced in an object-oriented manner in order to reproduce them on a computer. Use the technique. This technique is centered on the concept of “things (objects)”, and defines a circuit node class (FIG. 3) and a relay circuit class (FIG. 4) as “classes”.

<Circuit class structure>
FIG. 3 is a class diagram of the circuit node class.
(Circuit node class)
In the present embodiment, as shown in FIG. 3, in order to express the object of the relay circuit, a class diagram centered on an abstract class “circuit node” is defined. The class diagram format conforms to UML (Unified Modeling Language). The network of relay circuits can be represented by the connection relationship of circuit nodes, so that nodes can be provided at connection branch points and the direction of connection (left and right, up and down) can be set so that the circuit can be output and represented on the drawing. I did it. The arrows (←, →) in FIG. 3 indicate the direction of association, “0..1” represents the number of associations, the number on the left is the minimum number, and the number on the right is the maximum number. Note that the number part marked with * indicates infinity. The elements that constitute the circuit, such as a lever contact, a landing button contact, a power supply, a diode, a node, a relay body, and a relay contact, are all inherited from the circuit node. Δ indicates inheritance. The following explains the inherited class by purpose.

(1) Classes directly related to the classes in the interlocking chart The levers and landing buttons that appear in the interlocking chart are directly used as contacts in the relay circuit. The lever includes a “lever contact” class, and the landing button includes a “button contact” class, which are related to each other. ◇ indicates inward. Note that the lever contact has information on contact positions such as N, R, CN, and CR.
(2) Class related to relay The “relay body” class has data of name, type, timepiece, presence / absence of slow motion unit, and normal operation position. The “relay contact” class has data on the common side direction and contact position. The relay contacts are contained in the relay body and are related to each other.
(3) Classes that represent circuit branch points A “node” class is provided as a branch point in the connection diagram. In order to make it easy to represent the connection status of the relay network on a computer, the nodes that are directly connected are aggregated. Thus, an “aggregate node” class is defined, and the node class is included and related to each other. Further, circuit nodes connected to the branch points are related to four directions (upper left, lower left, upper right, lower right).
(4) Class expressing circuit end point and direction A “power source” class is provided as a class connected to a power source, and a “diode” class is provided as a class representing a diode.

FIG. 4 is a class diagram of the relay circuit class.
(Relay circuit class)
As a class for processing automatic generation of a relay circuit, an abstract class called “relay circuit” class is defined as shown in FIG. 4 to create a circuit representation, circuit generalization, and processing flow. This class includes relays, aggregate nodes, power supplies, and diodes used in the circuit, and inherits them to individual relay circuits.
In an individual circuit class, logical data of an interlocking chart can be acquired by relating to an object of the interlocking chart.

  For example, the proximity lock relay circuit among the relay circuits is basically related to the signal one-to-one. However, the relationship from the signal lever to the relay circuit is 0 or 1 if there is no inward turning device or counter route, and conversely, the relationship from the circuit to the signal lever is the same in the same direction. Since there are cases where signal levers of points are shared, a plurality of associations are possible. The number of shares is normally up to 3 signal levers. As a relay operated by a circuit, an essential locking relay (ASR) and a locking auxiliary relay (MSlR) which are essential, and a track auxiliary relay (TSSlR) installed as necessary are included.

<Generalization of standard connection diagram>
Although the relay circuit connection network is conceptually standardized, the implementation form varies greatly depending on the station. For this reason, the standard connection diagram stipulated in the relay interlocking device is not a standardized circuit form, but is a collection of cases. In order to realize automatic generation by a computer, it is necessary to define logically strictly, so the standard connection diagram is generalized.
The relay circuit connection network is divided into several meaningful large groups of circuit blocks for each circuit type, and an overall network circuit is constructed by connecting the circuit blocks. Inside the circuit block, a network of circuit blocks is further constructed as necessary, and the process is repeated until the circuit block is simplified. In the most subdivided circuit block, serial and parallel circuits by circuit nodes are defined in association with the logical data of the interlocking chart. The relay circuit necessary for the interlocking device can be divided into about 10, but an approach lock relay circuit will be described as an example.

FIG. 5 is a diagram showing an example of a generalized approach locking relay circuit.
The circuit block of the proximity lock relay circuit which is a part of the standard connection diagram can be generalized as shown in FIG. An approach locking relay circuit is a circuit which drives each relay of TSS1R, ASR, and MS1R. Thus, when defining the network circuit by the circuit block of the approach locking relay circuit, for example, taking the route opening circuit block A in the approach locking relay circuit as an example, further, the basic route opening circuit block A1, It is defined by the overrunning switch opening circuit block A2 and the advance path opening circuit block A3. It should be noted that the final stage circuit block in the approaching lock relay circuit is defined to construct a specific contact in association with the interlocking diagram object.

Still further, the basic route opening circuit block A1 includes a parallel circuit of a route lever relay contact associated with the route and a switch indicating relay associated with the switch opening condition for opening the route, The circuit configuration is connected in series by the number of routes in the lever.
In addition to this “close-locking relay circuit”, the “track lever relay circuit”, “track locking relay circuit”, “signal control relay circuit”, “turn-off control relay circuit”, etc. that constitute the relay circuit, etc. Based on the data of the generalized standard connection diagram, the relay circuit connection network data generation device generates the relay circuit connection network data. In addition, as a large group of circuit blocks constituting the relay circuit, other circuits such as “route selection relay circuit”, “overall control relay circuit”, “route check relay circuit”, “driving direction control relay circuit”, etc. A block exists.

  In other words, the relay circuit connection network data generation device constructs an instance (entity) of the circuit class and its relationship from the linked diagram data according to the generalized standard connection diagram, thereby enabling the network logic circuit of the relay circuit connection network data. Is automatically generated. In addition, since there are some conditions that cannot correctly generate relay circuit connection network data only by using the interlocking chart, the automatic generation accuracy of the relay circuit connection network data is improved by inputting these in advance as supplementary conditions.

<Setting supplementary conditions>
The condition set as the supplementary condition cannot be determined only from the interlocking chart, but can be determined as a standard. Therefore, after the provisional automatic generation by the system is performed, the user performs manual correction. In other words, the relay circuit connection network data generation device saves the temporary automatic generation result of the relay circuit connection network data as data in the object of the linked diagram, and generates the actual object when the relay circuit connection network data is automatically generated, which will be described later To do. Circuits for setting supplementary conditions include an approach lock relay circuit and a path lock relay circuit. The provisional automatic generation of the approaching lock relay circuit will be described.

(Relay name setting)
Temporary automatic generation is based on registering the relay name by adding “ASR” or “MS1R” to the lever name for each signal lever registered in the interlocking chart. Note that signal levers having the same number of routes and having the same landing point in the same direction have the same relay name up to three levers. The TSS1R relay is installed when it is necessary to maintain inward entry. In many cases, the unlocking element is installed in a traffic light of 60 seconds or longer, but this is not the case. For this reason, in this relay circuit connection network data generation device, in temporary automatic generation, it is generated for all traffic lights. As for the name, “SS1R” is added to the name of the first track circuit holding the inward approach.

(Inward approach retention setting)
Inward approach holding is to detect that the train has entered the inside of the traffic light and hold it to the end point of the route, thereby preventing untimely unlocking due to lever repositioning. For this reason, it is fundamental to set all track circuits from the inside of the traffic light to the landing point for each route. However, the closed and locked track circuit is omitted.

(Setting the number of unlocked track circuits)
The number of unlocked track circuits is normally two tracks, but is only one track circuit when there is only one track circuit in the traffic signal in the forward path or when entering the closed section.

(Setting of approach path lock)
The approach path lock is such that the approach lock has the function of the path lock and the path lock is omitted. If the first path segment lock that is continuous with the approach lock is not shared with the other path segment locks, it is provisionally automatically generated as the approach track lock.

(Correction of supplementary conditions)
When the provisional automatic generation as a result of the setting of the relay name, the setting of the inward approach holding, the setting of the number of unlocked track circuits, and the setting of the approach path locking is completed, the relay circuit connection network data generating device A temporary automatic generation result is shown, and a linked operation supplement condition setting screen for setting supplement conditions is output to the monitor. If necessary, supplementary conditions are registered on the screen from the user.

<Automatic generation of relay circuit objects>
Next, the relay circuit connection network data generation device generates an object of each relay circuit constituting the relay circuit connection network from the relation with the interlocking diagram object, and automatically generates a necessary relay. For example, in the case of a route lever relay circuit constituting a relay circuit connection network, the route lever relay circuit has a one-to-one relationship with the route. Then, the relay circuit connection network data generation device generates a circuit object of the route leverage relay circuit for each route, and automatically generates a route leverage relay as internal information. The proximity lock relay is associated with the signal, but the relay name is set by the supplementary condition setting, and the circuit object is shared for the signal lever having the common relay name. In this way, the circuit object and the relay circuit included in the circuit object are automatically generated for all the relay circuits constituting the relay circuit connection network.

FIG. 6 is a functional block diagram of the relay circuit connection network data generation device.
FIG. 7 is a diagram showing a processing flow of the relay circuit connection network data generation device.
In FIG. 6, reference numeral 1 denotes a relay circuit connection network data generation device. Then, the relay circuit connection network data generation device 1 includes a control unit 11 that controls each processing unit of the relay circuit connection network data generation device 1 and an interlocking chart data input unit 12 that performs processing under the control of the control unit 11. , The relay circuit determination unit 13, the supplemental condition input unit 14, and the relay circuit connection network data generation unit 15. The relay circuit connection network data generation device 1 also includes a database 16 that stores data used for each process, and a connection diagram display unit 17 that performs layout processing of the generated relay circuit connection network data and outputs the data to a monitor or the like. ing. Each processing unit of the linkage diagram data input unit 12, the relay circuit determination unit 13, the supplementary condition input unit 14, the relay circuit connection network data generation unit 15, and the connection diagram display unit 17 controls the program of the relay circuit connection network data generation application. When the unit executes, the computer of the relay circuit connection network data generation device 1 is configured. The database 16 is configured on a memory or a hard disk drive of the relay circuit connection network data generation device 1.

Here, the interlocking chart data input unit 12 is a interlocking chart data composed of a schematic wiring diagram representing the line alignment of the railway track and the installation state of the railway signal equipment, and an interlocking table describing the control conditions of the railway signal interlocking device. Is a processing unit.
In addition, the relay circuit determination unit 13 is a processing unit that determines which relay circuit is required among a plurality of relay circuits of different relay types constituting the entire relay signal of the railway signal based on the linked chart data. It is.
In addition, the relay circuit connection network data generation unit 15 determines a relay component of the determined relay circuit block by using the relay circuit connection network data generation program and the linkage chart data for the determined relay circuit block. And a processing unit that generates a connection diagram in the relay circuit block using the determined relay component.
The supplementary condition input unit 14 is a processing unit that inputs supplementary conditions for determining whether or not a relay component is necessary.
In addition, the connection diagram display unit 17 is a processing unit that identifies and displays a circuit layout of each relay constituent element constituting the generated relay circuit connection network data.

Next, the processing flow of the relay circuit connection network data generation device will be described in order.
First, the control unit 11 of the relay circuit connection network data generation device 1 instructs the start of processing. Then, the interlocking chart data input unit 12 reads the interlocking chart data recorded in the database (step S101). And the control part 11 produces | generates the object of the said interlocking chart data (step S102). Further, the relay circuit determination unit 13 needs any relay circuit among a plurality of relay circuits that may constitute the relay circuit connection network from the identification information of the relay circuit components recorded in the interlocking chart data. Is determined (step S103). Here, as the generation target of the relay circuit connection network data, “approach lock relay circuit”, “track lever relay circuit”, “track lock relay circuit”, “signal control relay circuit”, “turn control relay circuit” ”Is determined. Then, the relay circuit connection network data generation unit 15 starts generation processing of the relay circuit connection network data. In the following, details will be described by taking as an example the generation of relay circuit connection network data for an “approach locked relay circuit” among the relay circuits determined to be necessary.

  When the relay circuit is determined, next, the relay circuit connection network data generation unit 15 performs provisional automatic generation of the interlocking operation supplement condition (step S104). In the provisional automatic generation of the interlocking operation supplementary conditions, the relay circuit connection network data generation unit 15 analyzes the interlocking chart data, decomposes it into relay components such as a lever and a contact, and generates a list thereof. Moreover, the relay circuit connection network data generation part 15 hold | maintains the relevant information which shows which other relay component is connected to each relay component obtained by decomposition | disassembly of interlocking chart data. Then, the supplementary condition input unit 14 displays the provisional automatic generation result (relay constituent element list, related information between relay constituent elements, etc.), and monitors a linked operation supplementary condition setting screen for setting supplementary conditions. (Step S105). The user selects a supplemental condition for the relay circuit determined to generate the relay circuit connection network data on the displayed linked operation supplemental condition setting screen, and registers it in the relay circuit connection network data generation device 1.

  The supplementary condition is information for designating a relay circuit that the user determines to be further necessary for generating the relay circuit connection network data corresponding to the interlocking chart data. The selection of the supplementary condition is, for example, selected from a list of supplementary conditions (identification information such as names of relay circuits determined to be further necessary) on the linked operation supplementary condition setting screen displayed on the monitor, This is done by pressing the registration button. Then, the supplementary condition input unit 14 inputs supplemental conditions selected by the user (step S106). Then, the supplementary condition input unit 14 temporarily stores the temporary automatic generation result including the supplementary condition information in the database 16.

  Next, the relay circuit connection network data generation unit 15 selects one relay circuit from among a plurality of relay circuits to be created (step S107). Then, the relay circuit connection network data generation unit 15 generates each relay circuit connection network data of the selected relay circuit block (step S108). At that time, the relay circuit connection network data generation unit 15 reads the relay circuit connection network data generation program for one selected relay circuit from the database 16. Then, the relay circuit connection network data generation unit 15 selects the selected relay circuit connection network data generation program for the selected one relay circuit and the selected temporary automatic generation result generated based on the object data of the interlocking chart data. Using the information about one relay circuit, the relay component of each relay circuit block included in the selected relay circuit is specified. Then, the relay circuit connection network data generation unit 15 holds the information of the identified relay components and the relationship information between the nodes of the relay components, and the relay circuit connection network for the selected one relay circuit Generate data.

  More specifically, when the relay circuit connection network data generation unit 15 generates the relay circuit connection network data of the “approach lock circuit”, the relay circuit connection network data generation unit 15 is used for the access lock relay circuit. The relay circuit connection network data generation program is executed. Then, a generalized circuit class of “approach lock relay circuit” is read from the provisional automatic generation result recorded in the database 16. The generalized circuit class of the “approach lock relay circuit” includes each relay circuit block (display lock circuit block, path opening circuit block, etc.) constituting the “approach lock relay circuit” as shown in FIG. The information of the relay component which comprises A, the connection relationship of these relay components, and the connection relationship with another relay circuit block, etc. are included. As shown in FIG. 5, the generalized circuit class of “approach lock relay circuit” is represented by a combination of circuit block classes for a plurality of small circuit blocks such as a display lock circuit block and a path opening circuit block. The Then, relay circuit connection network data is generated for these small circuit block classes.

FIG. 8 is a diagram showing an example of relay circuit connection network data generated based on the interlocking chart data.
FIG. 9 is a diagram showing a generation example of relay circuit connection network data of the display lock circuit block.
First, the relay circuit connection network data generation unit 15 generates relay circuit connection network data for the “display lock circuit block” from the generalized circuit block class of the “approach lock relay circuit” shown in FIG. . As shown in FIG. 9, the relay circuit connection network data generation unit 15 generates a temporary automatic generation result generated from the object data of the interlocking chart data based on the processing of the relay circuit connection network data generation program for the proximity lock relay circuit. Refer to the circuit block class of “closed lock relay circuit” included in the data. And the relay circuit connection network data production | generation part 15 produces | generates the data of the relay circuit connection network data which connected the drop contact of the signal control relay of a signal apparatus in series about the path | route which an approach locking relay controls. Thereby, the relay circuit connection network data for the “display lock circuit block” as shown in FIG. 9A is generated. More specifically, as shown in FIG. 8, the path controlled by 1RASR is 1RA and 1RB, and the signal control relays controlling the respective traffic lights are 1RAHR and 1RBHR, so this drop contact is connected in series. The relay circuit connection network data for the “display lock circuit block” including the information indicating this and the information of the identifier of each signal control relay is generated.

FIG. 10 is a diagram showing an example of generation of relay circuit connection network data of the basic route opening circuit block.
When the relay circuit connection network data generation unit 15 finishes generating the relay circuit connection network data for the “display lock circuit block”, the relay circuit connection network data generation unit 15 next connects to the node of the “display lock circuit block”. The relay circuit connection network data for the block is generated. As shown in FIG. 5, the “route opening circuit block” is a circuit block composed of a “basic route opening circuit block”, an “overrunning switch opening circuit block”, and a “first pulling path opening circuit block”. It is. Therefore, the relay circuit connection network data generation unit 15 generates the relay circuit connection network data of the “basic route opening circuit block” that is one of the circuit blocks constituting the “route opening circuit block”. In the generation of the “basic route opening circuit block”, the relay circuit connection network data generation unit 15 is generated from the object data of the interlocking chart data based on the processing of the relay circuit connection network data generation program for the approaching lock relay circuit. Refer to the circuit block class of “basic route opening circuit block” included in the data of the temporary automatic generation result. Then, as shown in FIG. 10, the relay circuit connection network data generation unit 15 detects the route controlled by the approaching lock relay from the circuit block class of “basic route opening circuit block”, and drops the contact point of the route lever relay. Are connected in series, and the drop contact point of the switch display relay that is opposite to the opening direction of the switch for opening the basic track for each track lever relay Generate data.

As a result, relay circuit connection network data for the “basic route opening circuit block” as shown in FIG. 10B is generated. More specifically, as shown in FIG. 8, the route is 1RA and 1RB, and the route lever relay is 1RAR and 1RBR, respectively. Therefore, the relay circuit connection network data for the “basic route opening circuit block” is Information indicating that the drop contacts are connected in series is included. Also, since the opening switch of 1RAR is 21 inversion, the relay circuit connection network data for the “basic route opening circuit block” is parallel to the falling contact of the switch display relay 21KNPR opposite to the opening direction. Contains information indicating that a connection is to be made. Also, since the 1RBR opening switch is 21-positioned, the relay circuit connection network data for the "basic route opening circuit block" is connected in parallel with the drop contact of the switch display relay 21KRPR opposite to the opening direction. Contains information indicating what to do. .
Note that the relay circuit connection network data generation unit 15 performs the same process for the “overrunning switch opening circuit block” and the “first pulling path opening circuit block” constituting the “route opening circuit block” by the same processing. Generate network data.

FIG. 11 is a diagram illustrating an example of generation of relay circuit connection network data of the proximity lock circuit block of the TSSlR relay.
When the generation of the relay circuit connection network data for the “route opening circuit block” is completed, the relay circuit connection network data generation unit 15 next performs the “approach chain” of the TSSlR relay connected to the node of the “route opening circuit block”. The relay circuit connection network data for the “lock circuit block” is generated. At this time, the relay circuit connection network data generation unit 15 is included in the data of the provisional automatic generation result generated from the object data of the linked chart data based on the processing of the relay circuit connection network data generation program for the approaching lock relay circuit. Refer to the circuit block class of “approach locked circuit block”. When the relay circuit connection network data generation unit 15 determines from the object data of the interlocking chart data that the track auxiliary relay (TSSlR) is present in the “approach lock relay circuit”, the approach as shown in FIG.
