In the figure, the upper part is a track diagram including a crossing No. XX, and the lower part is a relay sequence circuit for controlling the operation of a traffic signal, an alarm device, etc. of the crossing.
The creation of these drawings on CAD is well known, and a description thereof is omitted here.
Each symbol sign such as a railroad crossing alarm in the above-mentioned track diagram is as described in the lowermost part of FIG. 2 and is generally used in the past. Omitted.

<Track diagram / connection diagram color coding / color return>
Prior to the simulation, first, color coding is performed to confirm whether the tracks, connections, and symbol symbols in the created railway signal line diagrams and signal control connection diagrams are drawn on the correct layer. On the CAD screen, display is performed in a predetermined color for each track, connection, and symbol symbol, and the operator visually checks whether there is a difference in recognition on the CAD. After confirmation, the original color is restored by the color restoration process.
<Linearization / connection>
However, if an inappropriate figure is found, for example, even if it is a line, it is not on the line layer, and it is converted to the original designated figure. When the “designate conversion graphic” command is executed, an inappropriate line graphic is accurately converted into a line as shown in FIG. 3, for example, according to a predetermined prompt. In the case of a connection diagram, a figure to be connected is designated and connected as shown in FIG.

<Track / connection check>
Next, a line and connection check is performed. In automatic recognition of track diagrams and connection diagrams, automatic recognition cannot be performed correctly if the connection points of the tracks and connections are not accurately connected and the line segments are a little apart or overlapped. Therefore, those defects are repaired.
(1) Execute an “input allowable error” command and input an allowable error indicating how far the end points are to be connected by a predetermined prompt.
(2) A “zero length line segment removal process” command is executed to delete all line diagrams and connection diagrams in the drawing having the same start point and end point (zero length). Thereby, a point-like noise signal generated for some reason is removed.
(3) Execute “Duplicate removal processing” command to check the line overlap (the place where the same part overlaps) for all the line diagrams and connection diagrams in the drawing, and delete the overlapping part.
(4) Execute the “end point connection processing” command to search for all line diagrams and connection diagrams in the drawing at the end points, and to find other line diagrams that are at a distance equal to or less than the tolerance but do not completely match When the end points of the connection diagram are found, color-coded display is performed for all of them. And according to a predetermined prompt, it designates as a track diagram and a connection diagram to be excluded from the processing target, or performs processing for matching the end points.
(5) Execute the “integration processing” command to search for all the line diagrams and connection diagrams in the drawing at the end points, and find that there are no end points of other line diagrams and connection diagrams, that is, no branch points. In this case, color-coded display is performed for all of them. And according to a predetermined prompt, it designates as a track diagram and a connection diagram to be excluded from the processing target, or performs a process of integrating the two tracks and the connection into one.

<Continuation track designation / cancellation>
Next, the continuation line is designated or canceled. For convenience of drawing, the lines that are actually connected may be divided for convenience. In this case, it is made to recognize that it is connected by designating where and where.
(1) Execute the “Specify connection source line” command to specify the connection source line.
(2) Execute the “designate connection destination line” command to designate the connection destination line.
(3) The “connection process” command is executed to internally hold connection information for the two lines of the connection source and the connection destination specified, and to recognize that they are connected in the simulation.
(4) To cancel the connection, execute the “Specify line to be disconnected” command to automatically display the above connection information on the drawing, specify the release location at a predetermined prompt, and then click “Release processing”. The connection information retained internally is deleted by executing the command.

The quadrangular frame described so as to overlap the up and down lines extending in the left-right direction of the line diagram of FIG. 2 indicates the determination area in the present invention, and in the example of FIG. Nine areas are set.
Next, how to set the determination area will be described with reference to FIGS.
The determination area is automatically set in the computer. In FIG. 5, a track surrounded by the traffic signals 378 and 388 is set as the determination area 6. Similarly, the track surrounded by the traffic signal 388 and the crossing controller UE1 is set as the determination area 5. Hereinafter, each determination area is similarly set. These judgment areas are areas where trains are detected in order to control the operation of railroad crossing alarms, breakers, etc., by means of traffic lights, etc., when trains travel on the track and enter each area. Set every time.
In the case of the example in FIG. 5, it is assumed that neither an alarm device nor a breaker is set for the No. 2 level crossing and the No. 3 level crossing displayed as “002” and “003”.

Hereinafter, a method for setting the determination area will be described in detail.
<Specify track diagram>
Execute the “Instruction for Track Diagram” command and specify the track diagram to be simulated by a predetermined prompt. Here, the “graphic recognition process” is performed after selecting the graphic on the track diagram. In the “figure recognition process”, a line, a traffic signal, a traffic signal name, an AFO, a controller, an insulation, and a track circuit name are extracted from the selected graphic and are distributed. Hereinafter, the information of each figure is acquired by the procedures (1) to (4).
Here, AFO refers to an AFO transmitter and an AFO receiver. The AFO transmitter transmits a train detection signal, and the AFO receiver is the same when receiving and receiving a train detection signal. The relay of the name is turned on. When a train enters between the AFO transmitter and the AFO receiver, the train detection signal is cut off, the train detection signal does not reach the AFO receiver, and the relay is turned off. In order to detect that the train has arrived at the railroad crossing, the controller operates when the train is in a range of about 10 m before and after the rail to which the controller is attached. Insulation refers to a portion that is electrically insulated in a continuous line. By setting the insulation, a track circuit for train detection is configured for each predetermined area. The track circuit name is a name of the track circuit configured by insulation.
(1) Signals As shown in FIG. 6, the nearest point 14 and all the lines 12 are obtained for all the lines 12 selected from the reference point 13 of each symbol 11.
-The nearest signal name is selected as the name of the signal.
-The traveling direction is determined from the arrangement angle of the traffic light (for example, 0 ° is right and 180 ° is left). In the example of FIG. 6, the traffic light 11 is determined to have an arrangement angle of 180 ° and a traveling direction to the left.
Through the above processing, the figure ID, name, direction, dividing point 14, and track ID related to the traffic light are obtained.
(2) About AFO As shown in FIG. 7, the closest points 18a, 18b and the line 12 are obtained for all the lines 12 selected from the reference points 17c, 17d of the symbols 17a, 17b.
Obtain a name from the attribute information of each selected AFO.
-Determine the type of transmission / reception, uplink / downlink, and signal direction from the symbol code.
Through the above processing, the graphic ID, name, transmission / reception type, up / down direction, signal direction, dividing points 18a and 18b, and line ID relating to AFO are obtained.
(3) Controllers As shown in FIG. 8, the closest point to all the lines 12 selected from the reference point of each symbol 15 and the line 12 are obtained.
-The name is acquired from the attribute information of each selected control element.
-Judge the type distinction between always-on and always-off from the symbol code.
A point that is a certain distance away from a point on the track is obtained on each side, and set as a dividing point 16.
With the above processing, the graphic ID, name, ON / OFF distinction, dividing point 16 and line ID regarding the controller are obtained.
(4) Insulation As shown in FIG. 9, the closest point 22 to all the lines 12 selected from the reference point of each symbol 21 and the line 12 are obtained (usually, the insulation is on the end point of the line). .
Through the above processing, the figure ID, the break point 22 and the line ID relating to insulation are obtained.
The line is divided at all the dividing points obtained in the above (1) to (4). For example, a cross mark in FIG.

Next, a determination area is set according to the following procedure.
(1) As shown in FIG. 11, the connection of the line including a branch is searched and route information is acquired. For example, in the case of FIGS. 11A and 11B, the operation is as follows.
Route 1: Line A → Line B → Line C (see FIG. 11A)
Route 2: Line D → Line B → Line C (see FIG. 11A)
Route 3: Line E → Line F (see FIG. 11B)
(2) Lines divided by the above dividing points are made into areas, and area numbers are assigned to the areas (see FIG. 12). In addition, about the branch point of a track | line, an area is divided by a branch point (refer FIG. 13). In addition, station departure / arrival lines and tracks divided by track circuit names are in the same area.
The determination area is automatically recognized as described above, and the result is displayed on the CAD screen as shown in FIG. On this screen, contents can be added, changed, and deleted manually. In the case of a change, the cursor is placed on the “change” button arranged on the right side of the screen and clicked to switch to the change screen, and the determination area can be changed. Similarly, in the case of addition, by moving the cursor to the “Add” button arranged on the right side of the screen and clicking, the screen can be switched to the addition screen and the determination area can be added.

<Area distance setting>
The area distance setting process is necessary when the train is run at a certain speed as a simulation condition. When the “area distance setting” command is executed, a predetermined prompt is displayed, an area is designated according to the prompt, and a distance is input.
<Symbol display association>
In the simulation result display, the symbols on the relay are color-coded according to the energized state. The symbols on the track are also color-coded in conjunction with each other. Therefore, the symbol on the relay is associated with the symbol on the track diagram. When the “symbol display association” command is executed, a predetermined prompt is displayed, and a symbol on the relay is designated accordingly, and then a symbol on the line to be associated is designated. Then, the display color is selected.

<Run simulation>
FIG. 15 is a train position automatic calculation screen of a CAD computer for instructing the train position on the track diagram as an input condition of the simulation. As shown on the screen, the train length, the passing area, the approach time, and the speed Is supposed to be entered. By inputting these conditions, the train position on the track diagram is indicated, and the train position is displayed on the track diagram as indicated by 20 in FIG.

  FIG. 16 is a simulation condition setting screen of the CAD computer for setting the time required for ON / OFF operation of the relay of the relay sequence circuit, and is automatically set to a preset time according to the type of the relay. However, depending on the relay, there is a range in the required operation time. It comes to choose.

FIG. 17 is a flowchart of the simulation operation, and the simulation is executed based on the conditions set as described above.
Prior to executing the simulation, the command execution interval is set. That is, the time interval for updating the position of the train running on the track is arbitrarily set.
After completing such setting, the initial state is displayed in step S1. At this time, the train mark indicated by 20 in FIG. 19 is at the start position, and all the relays of the relay sequence circuit are displayed in the initial state. Next, in step S2, the train starts traveling at a preset speed on the route set in advance, and in step S3, the relay starts to operate as the train travels. In step S4, the traveling position of the train and the operating state of the relay are displayed as shown in FIG. In the processing from step S2 to step S4, ON / OFF of each relay at each time is determined as shown in FIG. 18 according to the simulation execution cycle and the train speed.
In step S5, it is determined whether or not the train has entered the determination area of the level crossing control section. If the train has entered the determination area of the level crossing control section, an affirmative determination is made in step S5. Alarms and traffic lights are activated. If the train has not entered the determination area of the level crossing control section, a negative determination is made in step S5, and in step S7, the level crossing alarm and the traffic signal in the above-described track diagram are not activated. In the next step S8, it is determined whether or not it is within the simulation section. If it is still within the simulation section, an affirmative determination is made in step S8, the process returns to step S2, and the subsequent processing is repeated. When the process is finished, a negative determination is made in step S8, and the simulation is finished.

  The result of the simulation is displayed as shown in FIG. 19, and the state of FIG. 19 is in the position of the determination area A as shown by 20 for the train, and the railroad crossing alarm 19 is activated. For the relay sequence circuit for that purpose, a circuit in a range indicated by “D” is in an activated state, and is displayed in a color different from other circuits. For example, the display color of the determination area A that detects the train on the track diagram changes from green to pink, and the display color of the relay sequence circuit in the range indicated by “D” in the operating state changes from white to red.

  FIG. 20 shows an example of displaying the simulation result in a time chart. In this case, if the relay on / off information is output in a CSV format file and an XLS file for chart output is used, it can be displayed in a chart format based on the output CSV file. The display is made at each simulation execution time interval, with each relay on / off state as a simulation result and each row as one relay behavior.

  In the embodiment described above, the train position on the track diagram is designated, and the simulation is performed by operating the relay sequence circuit diagram according to the position on the determination area of the train. Complicated manual input work for condition input can be eliminated. In addition, the simulation result indicates that the relay sequence circuit that is operating and the relay sequence circuit that is not operating are distinguishable, and the control target devices such as the operating crossing alarm and the control target devices that are not operating are displayed. Since it is displayed so as to be identifiable, it is possible to easily determine whether the circuit is normal or abnormal according to the train position.

  In the above embodiment, the contents described in the paragraph numbers [0017] and [0018] correspond to the area setting means of the present invention, and the contents described in the paragraph number [0020] correspond to the train position specifying means of the present invention. However, the contents described in the paragraph numbers [0022], [0023] and [0024] and the process described in the flowchart of FIG. 17 correspond to the display means of the present invention.

As described above, the embodiment of the present invention has been described. As the display means of the present invention, as described above, the display means is displayed using the railway signal line diagram, and the display means is displayed using the signal control connection diagram. These can be used in combination with those displayed using a time chart, or used alone. Moreover, although the said embodiment demonstrated the simulation of the connection diagram corresponding to the track | line including a level crossing, the connection diagram which does not include a level crossing, for example, a signal, a relay interlocking | linkage apparatus (point switching apparatus of the some track | line in a station premises) It can also be applied to a simulation of a connection diagram corresponding to the above.
In addition, the present invention can be implemented in various forms within the scope of the inventive idea.
