BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1 FIG. FIG. 1 is a diagram showing a configuration of a train operation management system according to Embodiment 1 of the present invention. In the figure, 1 is a central computer that manages train operation, such as tracking of trains based on interlocking information such as train location information and signal information, and route control of trains based on operation schedule information, and 2 is a change of train schedules and manual operation of routes. An operation console for inputting control and the like and outputting an alarm when an abnormality occurs, etc., 3 is an operation display panel for displaying train operation status (railing status, delay status, etc.) by interlocking information;
Reference numeral 4 denotes a central transmission device which is connected to the central computer 1 and transmits interlocking information and control information. The central computer 1, the command console 2, the operation display panel 3 and the central transmission device 4 constitute a central control device.

Reference numeral 5 denotes a transmission path as a transmission means constituted by a LAN or the like for performing transmission between the central transmission device 4 and a station transmission device 6 of each station described later. Reference numeral 7 denotes an interlocking device arranged at each station, which outputs control information to the traffic signal 9 and the track circuit 10 to control them, and also outputs signal information from the traffic signal 9 and information on the train 8 located on the train 8 from the track circuit 10. Enter the link information. Reference numeral 6 denotes a station transmission device that is connected to each interlocking device 7 and transmits interlocking information and control information. The station transmission device 6 and the interlocking device 7 constitute a station control device.

Numeral 11 denotes a trouble recorder connected to each of the station control devices 6 and 7, which will be described later in detail, and inputs interlocking information and control information from the station transmitting device 6 and the interlocking device 7 to which the trouble recorder is connected. Is always stored with the time.

Next, the operation, particularly, the operation of detecting an abnormality in the central computer 1 and the operation of storing information in the trouble recorder 11 will be mainly described. FIG. 2 is a flowchart for explaining an operation related to abnormality detection in the central computer 1. This operation is executed, for example, in a cyclic start that repeats a start every second. First, change information is collected in step S1. Here, the change information is information including information when there is a change in the control information and the interlocking information and a time at the time of the change. For example, FIG. 3 shows an example in the form of a table. That is, here, assuming that the input information represents the present information of the traffic signal, the train location information, and the output information represents the control information for the traffic signal, the same figure shows that the track circuit 1RT of the input information lifts at time t1. To the falling signal (ON), at time t2 the output information signal 5R changes from the stop indication to the progress indication signal (G), and at time t3 the input information track circuit 5RXT changes from the lifting to the falling signal (ON). , At time t4, the traffic signal 5R of the input information has changed from the progress indication signal to the stop indication signal (R).

These pieces of change information are stored for a certain period of time, and abnormality monitoring is performed (step S2). Here, the general abnormality monitoring items include, for example, “cannot set a route” and “indicate illegal stop”. The former corresponds to the case where the indication is not confirmed even after a predetermined time elapses on the route where the route setting output is performed from the central computer, and the latter does not move the train to which the route is allocated. This corresponds to the case where the signal indication becomes the stop indication as it is.

FIG. 4 explains an example of the presence / absence of the above-mentioned "unauthorized stop indication". Focusing now on the inside signal 1RB and the track circuit 1RXT installed at the entrance of a certain station S (FIG. (1)) When normal (no abnormality), the timing at which the G signal of the traffic light 1RB changes to the R signal and the OFF (non-railing, lifting) signal of the track circuit 1RXT changes to the ON (railing, falling) signal The timing is almost the same (FIG. 2B). On the other hand, as shown in FIG. 3C, even if a predetermined time Tm elapses from the timing when the G signal of the traffic light 1RB changes to the R signal, the signal of the track circuit 1RXT
If the FF signal does not change to the ON signal, it is determined that the abnormality is "illegal stop indication". The cause of these abnormalities may be a short circuit failure of the track circuit or a failure to display the traffic light due to a failure of the switch.

Returning to FIG. 2, if there is no abnormality (step S
(NO in 3) End as it is and if there is an abnormality (step S
If YES at 3), an alarm is output to the command console 2 to sound an alarm buzzer and notify the commander (step S4). Then, the trace data for a predetermined time is separately stored in the storage memory (step S5). The stored data, together with the stored data by the trouble recorder 11 described later, helps the data for investigating the cause of the abnormality. Finally, a start command is output to the trouble recorder 11, which will be described later (step S6), and the process ends.

Next, the operation of the trouble recorder 11 will be described. FIG. 5 is a flowchart for explaining the operation of the trouble recorder 11. The trouble recorder 11 is also executed periodically at regular time intervals, and first collects control information and interlocking information from the station transmission device 6 and the interlocking device 7 (step S7). Specifically, for example, FIG.
As shown in FIG. 3, these detailed information is stored in the unit memory # 1 of the memory 111 together with the time information.
When the storage capacity of No. 1 becomes full, the storage content is moved to the unit memory # 2, and new information is continuously stored in the unit memory # 1. By providing a total of N unit memories # 1 to #N and executing the storage operation in the above-described manner, as a result, information for a predetermined time T (T is, for example, about 15 seconds) can be stored. .

Returning to FIG. 5, it is determined in step S8 whether a start command has been issued. If there is no start command (N in step S8)
O) The process ends. If there is a start command (step S8
That is, as described with reference to FIG. 2, when the central computer 1 detects an abnormality, a trouble recorder start command is output (step S6 in FIG. 2), and the start command is transmitted to the central transmission device. When input to the trouble recorder 11 of the station related to the occurrence of the abnormality on the route of the 4-transmission path 5-station transmission device 6, the trace data is stored (step S).
9).

The operation of storing the trace data in the trouble recorder 11 will now be described with reference to FIGS. In FIG. 7, assuming that a start command is now output at time t0, at that timing, the memory 111 in FIG. 6 stores the past T hours from time t0 and starts at time b1 (t0−b1 = T). Information is stored.
Trace data is collected at time t when the start command is output.
It is executed not at 0 but at a timing when a predetermined time T1 (T1 is, for example, about 5 seconds) has elapsed from the time t0. That is, as shown in FIG. 7, an interrupt command is issued at the timing of time a1 (a1−t0 = T1) after a lapse of time T1 from time t0, and the contents stored in the unit memories # 1 to #N are changed. This is read and stored in the memory 112 (FIG. 6). The storage of the information in the memory 111 is continued regardless of the start command.

As a result, the memory 112 stores the time b1 before the start command output time t0 to the time a1 (a
1-b2 = T). In the case of the above specific numerical example, 1 before time t0
Information from 0 seconds to 5 seconds after time t0 is stored. In this way, the information after the start command is output is also stored, because in pursuit of the cause of the abnormality,
This is because empirical rules have shown that it is also important to grasp the phenomenon after the occurrence of the abnormality.

The contents stored in the memory 112 are transmitted to the central computer 1 through the route of the station transmission device 6-transmission line 5-central transmission device 4 and are operated by the commander, for example, the command console 2
In addition, the data is displayed using an output device such as a printer, and is used as material for investigating the cause of the occurrence of the abnormality and planning for the subsequent measures.

By comprehensively judging the change data collected by the central computer 1 before and after the occurrence of the abnormality in the change information and the storage data from the trouble recorder 11, the cause is determined by the interlock device at the site. It is also possible to determine whether it exists on the side or in data processing in the train operation management system.

If a data reading device is installed in a place where maintenance personnel are located, and this data reading device is connected to a trouble recorder 11 installed in each station via a telephone line or the like, necessary data can be appropriately packed. Will be available at
Maintenance personnel can quickly process without moving to the site, and maintenance work can be made more efficient.

Embodiment 2 In the first embodiment, the central computer 1 detects the occurrence of an abnormality from the change information and outputs a start command. However, the trouble recorder 11 that constantly stores the control information and the interlocking information outputs the start instruction. May be detected to output a start command. Although the target information is limited to the range related to the interlocking device of the station, it is possible to detect the occurrence of the abnormality of the detailed phenomenon correspondingly. Of course, the trouble recorder 11 may be configured to execute the storage of the trace data in response to an activation command output from either the central computer 1 or the trouble recorder 11 by using the abnormality detecting means based on the change information.
