FIG. 1 is a hardware block diagram showing an embodiment of a train operation reproducing apparatus according to the present invention. 11 in the figure
Is a central processing unit (hereinafter, referred to as CPU) that executes a predetermined calculation process based on program data,
Bus lines 12 such as address, data and control lines are derived from the CPU 11, and a CTC input / output device 13 and a diagram creating device 14 are connected to the bus lines 12.

This CTC input / output device 13 takes in CTC information such as track circuit information indicating train position, signal indicating information, train traveling direction information, etc. at predetermined intervals and stores them in a memory (not shown) together with time information. It has a function of temporarily storing and outputting route control information and artificial operation information.

On the other hand, the schedule creating device 14 creates schedule data which is a departure / entry timetable of each station in each train while exchanging data with an internal man-machine (not shown), and the schedule data is created. The timetable data is stored in a built-in memory (not shown) or the like.

Further, the bus line 12 stores a program memory 15 for storing a data storage processing program, a reproduction display processing program, etc., a magnetic disk device 16 which is an external storage device for storing various information, and artificial operation information. Various data stored in the man-machine device 17 and the magnetic disk device 16 which is input and displays the stored data of the magnetic disk device 16 and which displays the display information processed by the reproduction display processing program are printed. A printer 18 for outputting is connected.

Therefore, the CPU 11 fetches the CTC information together with the time (date and time) information from the CTC input / output device 13 and stores the CTC information in the magnetic disk device 16, and also the CTC information of the CTC input / output device 13 and the diamond of the diagram creation device 14. From the data, the magnetic disk device 16 is provided with the tracking information of the train in which the time (date and time) is associated with the train with a certain train number, for example, information having a train time deviation from a fixed time.
To store. Further, the CPU 11 outputs route control information from the CTC input / output device 13 based on the CTC information, train tracking information, and the like, and by performing necessary operations from the man-machine device 17 as necessary.
At this time, the route control information associated with the time is stored in the magnetic disk device 16 as described above. Also, CPU1
1 inputs various operation information artificially from the man-machine device 17, for example, information for controlling a traffic light, and outputs it from the CTC input / output device 13. At this time, the operation information associated with the time is magnetized. It is stored in the disk device 16.
Therefore, the magnetic disk device 16 is provided with at least a CTC information area 16A, a train tracking information area 16B, a route control information area 16C and an operation information area 16D as shown in FIG. , Train tracking information, route control information and operation information will be stored.

Further, the CPU 11 fetches various information including train tracking information and route control information from each of the information areas 16A to 16D of the magnetic disk device 16 based on the reproduction display processing program and draws (edits).
The display data representing the obtained train operation status is displayed on the CRT of the man-machine device 17, and the operation status of the train can be reproduced and displayed on the CRT screen. Next, the operation of the train operation reproduction device configured as described above will be described.

First, with reference to FIG. 3, an example in which various types of information relating to the operating status of a train are stored will be described. When the apparatus is started up or the timetable data is changed, timetable data already secured in the external apparatus is input from the timetable creating device 14 and stored (ST1). In this state, the CPU 11 fetches the CTC information coming into the CTC input / output device 13 based on the data storage processing program of the program memory 15 as shown in ST2, but at this time, it judges whether or not the CTC information has changed ( ST3), if there is a change, the information that the train has moved together with the time information is displayed in the CTC information area 16 of the magnetic disk device 16.
It is saved in A as history data (ST4).

Thereafter, the CPU 11 externally activates the CTC.
While the CTC information input to the input / output device 13 is stored in the magnetic disk device 16 together with the time information, the train tracking process is executed from the CTC information and the diamond data (ST
5) Judge whether all of the tracking information of the train which is the result of the tracking processing or the tracking information needs to be saved as shown in step ST6, and only when it is necessary to save the tracking information of the train required. Is stored in the train tracking information area 16B of the magnetic disk 16 together with the time information (ST
7).

Further, it is judged from the result of the tracking process of the train whether or not the route control is necessary (ST8). That is,
From the result of the tracking process of the train, for example, the train is approaching a certain station, or the preceding train is approaching a certain station while the following train is approaching, and further, two trains are used by using the main line and the branch line. When it is necessary to guide the train by crossing or changing the color of the traffic signal in order to secure so-called safe operation of the train, the route control processing is executed based on the tracking information of the train (ST9). The route control information obtained as a result of this execution is output from the CTC input / output device 13. At this time, all of the route control information or step ST1.
As shown in 0 and ST11, the route control information required only when it is necessary to save the history data is stored in the route control information area 16C of the magnetic disk device 16 together with the time information.

When a series of processing is completed under a certain CTC information, the process is returned to step ST2 and a series of processing is performed based on the next CTC information (ST2 to ST11).
Is repeatedly executed.

Therefore, by executing such a series of processes, not only the CTC information as in the prior art, but also the train tracking information and the route control information are recorded on the magnetic file device 1.
6 can be surely recorded, so that when the train operation trouble occurs, the operation status can be displayed or printed out, and a more appropriate trouble investigation can be carried out. Further, since the CTC information, the train tracking information, the route control information, the operation information and the like are individually stored in the magnetic disk device 16 together with the time information, for example, only the train tracking information or only the route control information is printed out. You can check the operation status and systematically organize the operation status of the train. Next, an example of reproducing and displaying the operation status of the train will be described with reference to FIG.

In the processing of FIG. 4, after the operation is started, the reproduction display start time is set, and then the necessary information is taken out in time series from the magnetic disk device 16 based on the drawing program and the drawing processing is executed. , C of man-machine device 17
Displaying on RT.

Specifically, after the operation is started, when data necessary for processing, such as reproduction display start date and time (including minutes and seconds) and reproduction end, are input from the man-machine device 17 (ST21), the man-machine concerned. It is determined whether the input from the device 17 is the end input (ST22). However, at this point, since the display data is to be converted into display data based on the reproduction display processing program, it is determined that there is no end input, and the process proceeds to the next step ST23. Here, it is determined whether or not the reproduction display start date and time is input from the man-machine device 17, and when it is determined that the reproduction display start date and time is input, the data of the reproduction display start date and time is set in an appropriate memory (ST24),
Return to the man-machine input processing ST21.

Then, steps ST21 to ST23 are executed again.
Processing is executed, and the process proceeds to step ST25 to determine whether or not the data of the reproduction display start date and time is set in the memory. If it is determined that the reproduction display start date and time data is set, the magnetic disk device 1
After taking out the history data relating to the reproduction display start date and time from each of the information areas 16A to 16D of No. 6 (ST2
6), edit processing of display data is executed (ST27, S
T28).

In this editing process, a line, a traffic signal, etc. are typically constructed in accordance with the reproduction display processing program and displayed on the CRT of the man-machine device 17, and the magnetic disk device 16 is accompanied by time information relating to the reproduction display start date and time. The CTC display information, the tracking information, the route control information, the operation information, and the like are sequentially taken out, a train is drawn on the track at the position of the train at that date and time, and the color of the signal at that date and time is displayed in color on the signal.

After that, as shown in step ST29,
When the reproduction display start time is updated again, the process returns to the man-machine input process, and by repeating the same process, a train is drawn with dynamic changes, and the color of the traffic signal changes moment by moment, and the operating status is visualized. It can be reproduced accurately and accurately.

In this way, the series of processing shown in FIG. 4 is repeatedly executed in accordance with the reproduction display processing program. At that time, the man-machine input processing ST21 and then the step ST22 are executed.
When it is determined whether there is an end input in step S4, if the end input is input from the man-machine device 17, it is determined that the program processing is ended, and the reproduction display start date and time set in step ST24 is cleared (ST30).

Therefore, by executing the series of processes shown in FIGS. 3 and 4, the train operation history at the time of occurrence of a failure is displayed as C
It can be visually displayed on the RT display in a graphical and time-series manner. Moreover, since the tracking information and the route control information can be reproduced in a graphic and time-series manner and displayed visually, it is possible to improve the efficiency in failure investigation analysis.

In the above embodiment, each time the operator inputs the reproduction display start date and time, the information relating to the reproduction date and time is taken out from the magnetic disk device 16 to perform the drawing process. By inputting the reproduction display start date and time, the series of processes in FIG. 4 may be repeatedly executed within a range of the input date and time at a predetermined time, for example, a minute unit. Further, in FIG. 4, the determination in step ST22 and the clearing process in step ST30 may be processing procedures performed after step ST23 or step ST28. In addition, the present invention can be modified in various ways without departing from the scope of the invention.
