Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an improvement in a train operation management system suitable for subways and suburban trains.

[Prior art]

Does a train operation management system control the operation of all trains within the target route? Monitor and display and broadcast information on the approach, arrival, and departure of trains at each station, and control various equipment such as switches and signals associated with train operation? It is something to do. Furthermore, systems including automatic train control equipment (ATC) and automatic train operation equipment (ATO) have recently appeared.

Explanation below? For the sake of simplicity, the explanation will focus on passenger information at stations, but it can be applied to any other system with functionalities.

Now, what is the structure of the conventional passenger information system? r[To explain with reference to Figures 1 and 2, first, as shown in Figure 1,
Assume that there is a line consisting of six stations, stations IA to IF'. 2
U is up + d, 2. D is the down line, and 31 to 35 are trains. 48 to 4F are the station equipment at station h, which provides the above-mentioned passenger guidance.

These station devices 4A to 4F are respectively the upper υ line control device 4.
Divided into AU~4F U and 4AD~4FD, upper,
! They are connected by a 7-line transmission line 5U and a lower line transmission line 5D, and are provided with solid devices 6U and 6Dr, respectively.

In this method, either one of the solid devices 6U or 6D
If the line goes down, passenger information and other operation management functions on one of the up and down lines will be disabled. Even if the up-line and down-line solid devices 6U and 6D' are disposed at both terminal stations IA and IF, the above-mentioned drawbacks do not change.

Next, as shown in Fig. 2, 7 units [t4A
It is also known to connect up to 4F through a transmission line 5 and to arrange dual system solid devices 61 and 62 at the same location. Other symbols are the same as in FIG. 1.

However, in this case, the dual system is powerless against external factors such as a power outage in the solid equipment, and as is well known, the dual system of computers cannot monitor each other or monitor each other. Another disadvantage is that the software configuration for switching is complicated. [Object of the Invention] An object of the present invention is to provide a highly reliable train operation management system.

[Summary of the Invention J In the present invention, a parent device is placed at both terminal stations of a target route, and a child device is placed at an intermediate station as appropriate. And between these parent and child devices? Connect with a loop transmission line. The parent device includes a means for storing train schedules of upper and lower drawing lines, a transmission control means capable of importing all information on the loop transmission route, an operation means capable of inputting changes to the train schedule, and inputting this change to each upper and lower line. and a switching means for enabling only one or both of the above. The slave device includes a transmission control means that takes in information related to at least one station on the loop transmission path, a train schedule taken in by this transmission control means, and input information from the relay interlocking device. A station control system (A and 7) is provided to carry out operation management.

By configuring the system in this way, it is possible to reduce the chance that two parent devices become abnormal at the same time, and when one parent device is running, the other parent device can perform operation management for the entire line. The reliability of gold can be increased.

[Embodiments of the invention]

FIG. 3 shows an embodiment of the uninvented grass cutting operation management system limited to passenger guidance.

The line consists of six stations, stations IA to IF, and has an up line 2U and a down line 2D, and trains 31 to 35 are in operation. Each of the seven units d4A to d4F is connected by a loop transmission line 8 via transmission control devices 78 to 7Ft. End station IA and IF on both Y1
station equipment 124A, 4FVCd solid equipment 6U, 6D, and operation panels 9U, 9D'. Rain solid equipment 6U,
Is 6D the train schedule for all up and down lines? I remember each,
The transmission control devices 7A and 7F can take in all the information on the loop transmission path 8. In this sense, the entire line can be controlled from each solid device. Further, the operation panels 9U and 9D are provided with operation means for inputting an operation to change the diagram of the upper and lower drawing lines. However, this control panel
During normal operation, only inputs such as change inputs for the up line at 9U and for the down line at 9D are set to be valid. Furthermore, on the operation panel 90.9D, there are an indicator lamp that indicates whether the solid device of the O-D hand blade is normal or abnormal, an indicator lamp that indicates which range of the upper and lower lines the current division of responsibility by the solid device is, and A button is provided for switching to control all lines. This button becomes effective only when the indicator lamp indicating the other party's abnormality is lit.

Are the above station devices 4A and 4F the parent devices? However, they also play the role of child devices for the 0 stations IA and IF, respectively.

The intermediate station devices 4B to 4Eij and the transmission control devices 7B to 7E, which are child devices, are connected to the loop transmission path 8, and information on the transmission path 8 related to at least one station? It is Noh that incorporates the elements. However, preferably, the transmission control device 7A,
A uniform transmission control device capable of receiving all 1n information will be used on the 7th floor and the same tJi.

The station control device 1011-10E is the transmission control device 7B to 7
Under the train schedule received via Ei and the track circuit information such as train position received from the relay interlocking device 11, the destination guidance display devices 12B to 12E and the guidance broadcasting device 13 [3-1
3E'refi control. In addition, adjacent station equipment 4A and 4
Train departure and arrival information can also be received from C.

In such fLRi configuration, the central dispatcher monitors the train operation information T deflection displayed on the operation panel 9U, 91),
If there is a disruption in train operation, the system will issue orders such as changing the train schedule or canceling passenger guidance. These are performed on the terminal station IA side for the up line 2U, and on the terminal station IF side for the down line 2D.

For example, assume that there is no power outage near station IA and that the solid equipment 6U and operation panel 9U have stopped functioning.

At this time, the transmission control device 7A uses known through communication to
Alternatively, if you use a known detour and do not block the loop transmission line 8, press button 7 [Function down in 4A? , transmission control device 7F.

It is easy to detect with the solid device 6D.

As a result, the abnormality of the other party is displayed on the operation panel 9D on the station IF side. The dispatcher saw this and pressed the switch button.
If a switching operation is performed on the station equipment 4F side to monitor and control both up and down lines, subsequent operation management of all lines can be performed using the operation panel 9D.

In this way, in order to prevent erroneous operations such as the 1# information content of change input for "ll'l" being input duplicated from each solid device or inputting different contents for each solid device, The receiver of the device is fixed with up/down υml?・Unless the other party's solid device goes down, the receiver is set to an interlock so that changes other than the line held cannot be input.These processes are This will be explained using the flows shown in FIGS. 4 and 5.

FIG. 4 is a processing flow for monitoring the status of the other party's solid device.

Step 41: Based on the control status information of the other party's solid device 6, which is periodically transmitted through the transmission line 8, it is determined whether the solid device 6 is normal.

Step 42: If the control status is normal, information will be displayed on the operation panel 9 indicating that the Ikenaka actual device 6 is operating normally and whether the control receiver is holding wires, etc.
Display with a lamp etc.

Step 43: In order to prevent duplication of control with the Ikenaka solid device 6 and erroneous operations as described above, control interlock conditions are set to fix the control sounds of the upper and lower lines.

Step 44: If the Ikenaka solid device 6 is abnormal (down),
Alarm displays such as a buzzer sound and a lamp (Ikenaka equipment abnormality) display on the operation panel 9 are issued.

Step 45 The control interlock condition set by step 43 is canceled.

Figure 5 shows the operation of the solid device 6! Control input from 119 (
This is a processing flow when a train schedule change input, etc.) is performed.

Step 51: Determine whether the control interlock condition has been released. If it has been released, the process advances unconditionally to step 53 and the input information is processed.

Step 52: The content of the input information is
Nouke judges the content based on the route it has. Specifically, does the state of the upper/lower selector switch match the control interlock conditions set in step 43 of FIG. 4? to decide.

If they match in step 53, then import the input information and process the recombination of the train schedule? conduct.

Step 54 If one condition is not met in step 52, a warning such as a buzzer sound is output as an error, and -
No further processing will be performed.

In this way, according to this embodiment, even if one parent device goes down, the chance that the other parent device goes down is reduced, and the other parent device can monitor all lines completely independently. ,
It is possible to realize a highly reliable operation management method that is less likely to cause functional failure of the entire system.

Also, there is no need to create a complicated connection between the parents, such as a dual system of sexual intercourse, and it is quite simple.

Of course, due to an abnormality in one parent device, the division of the other parent device can be automatically switched to all lines, or the division can be automatically restored to its original state when the function of one of the parent devices is restored.

〔Effect of the invention〕

According to the main statement ``1, is there a reliable train operation management system?
Can be provided.
